Find the midpoint of the line segment whose endpoints are (3,7) and (9,3)

Answer:

Step-by-step explanation:

R = report length

R = 40 + (3/8)R + (1/3)R

3/8 = 3*3/8*3 = 9/24

1/3 = 8*1 / 3*8 = 8/34

R = 40 + (9/24)R + (8/24)R

R = 40 + (17/24)R                         Subtract 17/24 from the left

R-17/24 R = 40

7/24 R = 40                                  Multiply both sides by 24

7R = 40 * 24

7R = 960                                       Divide by 7

R  = 960/7

R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138

Answer:

C

Step-by-step explanation:

The diagram shows the system in equilibrium. Left part consists of 3 circles, 2 triangles and 6 squares. Right part consists of 2 circles, 5 triangles and 3 squares.

If this system is in equilibrium, then the mass of the left part is the same as the mass of the right part.

The mass of the left part:

[tex]3\cdot 3+2\cdot \triangle +6\cdot 2=2\triangle+9+12=2\triangle+21\ grams[/tex]

The mass of the right part:

[tex]2\cdot 3+5\cdot \triangle+3\cdot 2=5\triangle +6+6=5\triangle +12\ grams[/tex]

Hence,

[tex]5\triangle +12=2\triangle +21\\ \\5\triangle -2\triangle =21-12\\ \\3\triangle =9\\ \\\triangle =3\ grams[/tex]

The mass of the triangle is 3 grams.

Given information:

A circle has a mass of 3 grams and a square has a mass of 2 grams.

From the given diagram of a mass balance, it can be concluded that:

Now, the left and right sides are balanced. So, the mass of left side will be equal to the mass of right side.

Let x be the mass of a triangle shape.

So, the value of x can be calculated as,

Final answer:

Mridul will take 14.4 minutes to jog around a rectangular park for a total of 6 rounds, considering the total jogging distance of 2.16 kilometers at a pace of 9 kilometers per hour.

Explanation:

To calculate the time Mridul will take to jog around a rectangular park for 6 rounds, we need to compute the total distance he will cover and then use his speed to find the time. The perimeter of the rectangle is the sum of all its sides. Since the park is 100m by 80m, the perimeter will be (2 × 100m) + (2 × 80m), which equals 360 meters. For 6 rounds, the total distance will be 6 × 360 meters = 2160 meters or 2.16 kilometers.

Next, we use the formula for time:

Time = Distance / Speed

Given Mridul's jogging rate is 9 kilometers per hour, we can convert this speed into meters per second to match the distance units by multiplying by 1000 and dividing by 3600 (the number of seconds in an hour), which gives us 2.5 meters per second. Finally, to find the time taken:

Time = 2160 meters / (2.5 meters/second)

This calculation results in 864 seconds, which when converted to minutes is 14.4 minutes. Therefore, Mridul will take 14.4 minutes to jog 6 rounds around the park.

Answer: 13

Step-by-step explanation: In this problem we're asked to rewrite as addition and then evaluate.

It's important to understand that minus a negative means the same thing as plus a positive so we can change 5 - (-8) to 5 + (+8).

Now we can simply add to get a sum of 13.

Therefore, 5 - (-8) or 5 + (+8) = 13

Answer: 13

Step-by-step explanation: We originally have the equation 5-(-8).

Flip everything around.

5 + (+8)

5 + (+8) = 13.

When it gives the keywords "rewrite as addition" you should know that you need the rewrite the equation an opposite way of what it was written.

In this case it was 5-(-8).

Flip the signs, 5+(+8).

Add 5 to 8 and get 13.

The solution is 112 objects

The total number of objects the 7 people from Pia's Pottery shop and Jason's Craft shop is A = 112 objects

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of objects be = A

Let the number of mugs in Pia's shop be = m₁

Let the number of bowls in Pia's shop be = b₁

Now , the value of m₁ = 29 mugs

The value of b₁ = 18 bowls

And ,

Let the number of mugs in Jason's shop be = m₂

Let the number of bowls in Jason's shop be = b₂

m₁ = m₂ and b₂ = 2 x b₁

Answer:

Yes, because (−1, −5) is below the line.

Step-by-step explanation:

The given inequality is [tex]y \leq  -\frac{3}{4} x - 1[/tex] .......... (1)

Now, rearranging this equality relation we get,

4y = - 3x - 4

⇒ 3x + 4y = - 4

⇒ [tex]\frac{x}{- \frac{4}{3} } + \frac{y}{- 1} = 1[/tex] .......... (2)

This equation is in intercept form and the line represented by this equation passes through the x-intercept [tex](- \frac{4}{3}, 0)[/tex] and y-intercept (0,-1).

Answer: x = -5

Step-by-step explanation: To solve this equation, we start by distributing the -4 through the parentheses on the left side.

So we have -4 times x which is -20x and -4 times -5 which is positive 20. So our equation now reads -20x + 20 = 120.

Solving from here, we subtract 20 from both sides of the equation and we have -20x = 100 and dividing both sides by -20, we find that x = -5.

The answer is 7.

The composite function (f o g)(x) is found by substituting g(x) into the f(x) expression. Upon simplification, (f o g)(x) when f (x) = x²+6x+5 and g(x) = 1/(x+1) is: 1/(x² + 2x + 1) + 6/(x+1) + 5.

To find the composite function (f o g)(x) when f (x) = x²+6x+5 and g(x) = 1/(x+1), we substitute g(x) into f(x). That is, wherever you see 'x' in f(x), replace it with what g(x) is equal to.

Start with f(g(x)) = f(1/(x+1)). In f(x), replace x with 1/(x+1), which gives us: (1/(x+1))² + 6*(1/(x+1)) + 5. This is the composite function (f o g)(x).

To simplify further: the first term '(1/(x+1))²' becomes '1/(x² + 2x + 1)', the second term '6*(1/(x+1))' becomes '6/(x+1)', and the third term is just '+5'. So the composite function (f o g)(x) simplifies to: 1/(x² + 2x + 1) + 6/(x+1) + 5.

Answer:

On that day 1500 children and 700 adults attended.

Step-by-step explanation:

Given:

There is a carnival. Children are $1.50 and adults are $4.

The total amount of money raised was $5050.

On this particular day there 2200 in attendance.

Now, to find the children and adults attended on that day.

Let the children attended be [tex]x[/tex].

And the adults attended be [tex]y[/tex].

The total number in attendance:

[tex]x+y=2200[/tex]

⇒ [tex]x=2200-y[/tex]........( 1 ).

Now, the total amount of money raised:

[tex]1.50x+4y=5050[/tex]

Putting the equation ( 1 ) in the place of [tex]x[/tex] we get:

⇒ [tex]1.50(2200-y)+4y=5050[/tex]

⇒ [tex]3300-1.50y+4y=5050[/tex]

⇒ [tex]3300+2.50y=5050[/tex]  

Subtracting both sides by 3300 we get:

⇒ [tex]2.50y=1750[/tex]

Dividing both sides by 2.50 we get:

⇒ [tex]y=700.[/tex]

The adults attended = 700.

Now, putting the value of [tex]y[/tex] in equation ( 1 ) we get:

[tex]x=2200-700[/tex]

⇒ [tex]x=1500.[/tex]

The children attended = 1500.

Therefore, on that day 1500 children and 700 adults attended.

Answer:

[tex] |60| = | - 60| [/tex]

Step-by-step explanation:

They are equal. When the negative sign is inside the box the absolute value is positive, when the negative sign is outside the box THEN it is negative.

Answer: equal to

Step-by-step explanation: Absolute value means distance from zero on a number line. To represent the absolute value of a number, we use a vertical bar on either side of the number like we see in this problem.

So for the absolute value of 60, we know that 60 is 60 units from zero on a number line which means that the absolute value of 60 is just 60.

For the absolute value of -60, we know that -60 is also 60 units from zero on the number line so the absolute value of -60 is also 60.

Now we know that the absolute value of -60 is 60 and the absolute value of 60 is also 60. Since 60 is the same as 60, it means that 60 is equal to 60.

Another way of thinking about absolute value is that no matter what number you have inside the absolute value, your result will always be positive except for 0 which has an absolute value of 0.

In other words, the absolute value of any number is the positive version of that number. Again, not including zero.

The solution of the given system of equations is,

[tex]x=\frac{b^2+ac}{a^2+b};\; y=\frac{ab-c}{a^2+b}[/tex]

Step-by-step explanation:

The given equations are :

x + ay = b          .......(1)

ax - by = c        .......(2)

We will use 'Substitution Method' to solve the given system of equations.

In this method, we will find out the value of either of the two variables that is 'x' and 'y' from one of the two equations in terms of the another variable  and then substitute that value in the other equation to find the value of the another variable.

Now, we will be finding out the value of 'x' in terms of 'y' from equation (1) and then substitute it in the equation (2).

Consider the equation (1), that is,

   x + ay = b ⇒ x = b - ay          ........(3)

Substitute the value of 'x' from (3) in (2), we get

  a(b - ay) - by = c

⇒ab - a²y - by = c

⇒-a²y - by = c - ab

⇒-y(a²+b) = c - ab

⇒y(a²+b) = ab - c

[tex]\implies y=\frac{ab-c}{a^{2}+b}[/tex]

Now, substituting the above value of 'y' in equation (3), we get

[tex]x=b-a(\frac{ab-c}{a^2+b})[/tex]

[tex]\implies x=\frac{b(a^2+b)-a(ab-c)}{a^2+b}[/tex]

[tex]\implies x=\frac{a^2b+b^2-a^2b+ac}{a^2+b}[/tex]

[tex]\implies x = \frac{b^2+ac}{a^2+b}[/tex]

Hence, the solution of the given system of equations is,

[tex]x = \frac{b^2+ac}{a^2+b} ;\; y = \frac{ab-c}{a^2+b}[/tex]

Answer:

18

Step-by-step explanation:

Find the equation for the line in slope-intercept form: y = mx + b.

x and y are points on the line. Points are written in the form (x, y).

m is the slope.

b is the y-intercept, when it hits the y-axis.

Substitute the point (4, 4) and slope. x = 4; y = 4; m = -2. Find b

y = mx + b

4 = (-2)(4) + b

4 = -8 + b

b = 4 + 8

b = 12

Get the equation of the line using slope and the y-intercept.

y = -2x + 12

Substitute -3 as x and find the missing y.

y = -2(-3) + 12

y = 6 + 12

y = 18

The point was (-3, 18)

Therefore the missing value for y is 18.

To find the y-value, you substitute the given points into the formula for slope and solve for 'y'. In this case, the required value of 'y' is 18.

The subject of your question is mathematics, specifically the concept of calculating the slope of a line. The slope (m) of the line through two points (x1,y1) and (x2,y2) is defined as m = (y2 - y1) / (x2 - x1). You are given that the points are (4,4) and (-3,y) and the slope is -2. Substituting the given points into the formula gives -2 = (y - 4) / (-3 - 4 ). Solving this equation will give you the value of 'y'.

First, simplify the denominator to get -2 = (y - 4) / -7. Afterward, multiply both sides by -7 to eliminate the fraction: -2 * -7 = (y - 4). This yields 14 = y - 4. Solve for 'y' by adding 4 to both sides of the equation, which gives that y = 18.

Answer:

it should be a 50:1 gas oil ratio.

Step-by-step explanation:

Option A

It is a function because at any given time the oven was exactly one temperature.

Solution:

Given that,

At 5:00 p.m., Antonio turned on the oven

While the oven preheated, the temperature in the oven increased from 72°F to 400°F over a 10-minute period

The oven remained at 400°F for 45 minutes until Antonio turned it off

It took 60 minutes for the temperature in the oven to cool, returning to 72°F at 6:55 p.m

From above information,

5:00  ------------ 72°F

5:10 ------------------ 400°F

5:45 ------------------ 400ºF

6:55 -------------------- 72°F

Thus at any given time (input) the oven was exactly one temperature  (a single output )

Therefore the statement that best explains is:

Domain is the set of all x-values for which a function is defined (x axis).

Range is the set of all y-values for which a function is defined (y axis).

We are said that range of y = Sin x is the set of all real numbers.

If we look at the graph and look at the y-values for which the function is defined, we see that the Sin Curve oscillates between y = -1 and y = 1.

So the range would be:

[tex]-1 \leq y \leq 1[/tex]

It is not defined for other values, certainly not for ALL REAL NUMBERS!

To simplify the expression 7[63 ÷ (52 – 22) – 1], perform the operations inside the parentheses first, followed by division, subtraction, and multiplication in that order. The simplified form of the expression is 14.

Explanation:

To find the simplified form of the expression 7[63 ÷ (52 – 22) – 1], we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).

Within the parentheses, we first simplify the exponent, so we calculate 52 – 22 which is 25 – 4.

Perform the subtraction inside the parentheses: 25 – 4 equals 21.

Next, we divide 63 by 21, which equals 3.

Subtract 1 from 3 to get 2.

Finally, multiply 7 by 2 to get the simplified expression, which is 14.

Thus, the simplified form of the expression is 14.
