Simplify -5/1 the slope

Volume of a rectangular prism is V = L x W x H

The length for the small prism is 6

The width for the small prism is 4

The height for the small prism is 3

So 6 x 4 x 3 = 72

The length for the large prism is 16

The width for the large prism is 9

The height for the large prism is 2

So 16 x 9 x 2 = 288

Now you add the two volumes together: 288 + 72 = 360 ft cubed.

Answer: [tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{7}[/tex]

Step-by-step explanation:

To find the inverse , all we need do is to make x the subject of the formula.

y = 7x - 10

Add 10 to both sides

y + 10 = 7x

divide both sides by 7

Therefore:

x = y + 10 / 7 , that is

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{7}[/tex]

Answer:

Step-by-step explanation:

y=7x-10  calculate x :  7x-10 =y

7x = y+10

x = 1/7 y +10/7

the inverse of y=7x-10 is ; y = 1/7 x +10/7

Answer:

Option B.) 3 inches

Step-by-step explanation:

Let us first express some principles that we can use to solve our problem. Generally, the Volume of a Box is given by:

[tex]V=h*w*l[/tex]

where

[tex]V[/tex] : is the volume

[tex]h[/tex]   : is the height

[tex]w[/tex]   : is the width

[tex]l[/tex]   : is the length

Now we know that:

Volume of Box A ( [tex]V_{A}[/tex] )  is Equal to Volume of Box B ( [tex]V_{B}[/tex] ) so we have:

[tex]V_{A}=(2in)(3in)(6in)\\V_{A}=36 in[/tex]

So now we can find the Length ( [tex]l_{B}[/tex] ) of Box B easily, as we now the volume along with the height and the width, as follow:

[tex]V_{A}=V_{B}=36in\\\\36in = (3in)(4in)l_{B}\\\\36in=(12in)l_{B}\\\\l_{B}=\frac{36in}{12in}\\ \\l_{B}=3in[/tex]

So the Length of Box B is 3 inches, thus Option B. is correct.

That is  4x+7z-x+5-(4z)=3(x+z)+5

Step-by-step explanation:

to work out surface area you need to figure out the area of each face on the shape.

the first side is 7.5 x 9 = 67.5

there are two of these sides

this makes 135mm

the top side is (4.5 x 6) / 2

this makes 13.5

there are also two of these sides making 27mm

finally the back side is 4.5 x 9 = 40.5

there are only one of these sides

this makes 40.5mm

finally you need to add all these sides

135 + 27 + 40.5 = 202.5

the surface area is 202.5mm

Step-by-step explanation:

The pattern is 3 letters before.

Greater than bc the pieces is bigger

The two numbers are 15 and 6

Solution:

Let the two number be "a" and "b"

Let the first number be "a" and second number be "b"

Given that,

The difference between two numbers is 9

a - b = 9 -------- eqn 1

The first number plus twice the other number is 27

First number + twice the second number = 27

a + 2b = 27 ---------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

a = 9 + b ------ eqn 3

Substitute eqn 3 in eqn 2

9 + b + 2b = 27

3b = 27 - 9

3b = 18

Divide both sides of equation by 3

Substitute b = 6 in eqn 3

a = 9 + 6

Thus the two numbers are 15 and 6

Answer:

the answer is b

Answer:

See attachment

Step-by-step explanation:

The given system is

2x-y=4

x-y=-2

We write the system in slope-intercept form:

y=2x-4

y=x+2

The first equation has slope of 2 and y-intercept at (0,-4)

When y=0, x=2.

We plot (0,-4) and (2,0) to graph this first equation.

The second equation has a slope of 1 and a y-intercept at (0,2)

Also when y=0, x=-2.

We plot (0,2) and (-2,0) and draw a straight line through them.

The graph of the system is shown in the attachment.

Answer:

y=8x-69

Step-by-step explanation:

you would use the equation y-y1 = m (x - x1)

plug in m = 8 , y1 = 3, x1 = 9

now you have y - 3 = 8 (x-9)

distribute 8 --> y-3 = 8x - 72

add three to both sides to get y = 8x - 69

Answer:

[tex]y-3=8(x-9)[/tex]

Step-by-step explanation:

We are given that a line has a slope (m) of 8 and passes through the point (9,3).

We want to write the equation of this line.

There are three ways to write the equation of the line:

As the problem doesn't specify that we have to write the equation in a specific format, any one of the three work.

However, let's write it in point-slope form, as it is the easiest one to write in this case.  

As we are already given the point and the slope, we can plug them into the equation.

Starting with the slope, substitute 8 as m in the equation.

[tex]y-y_1=8(x-x_1)[/tex]

Now, substitute 9 as [tex]x_1[/tex] and 3 as [tex]y_1[/tex].

We get:

[tex]y-3=8(x-9)[/tex]

The Total earning of Paula riddle from 6 pm to 11 pm is $7.25  

Step-by-step explanation:

Given as :

Paula riddle charges per hour before 9 pm = $2.25 per hour

Paula riddle charges per hour after 9 pm = $2.75  per hour

Let The Total earning of Paula riddle from 6 pm to 11 pm = $A

Now, According to question

∵ before 9 pm , charges = $2.25 per hour

The time spend between 6 pm to 9 pm = 3 hours

So, The charge between 6 pm to 9 pm = $2.25 per hours × 3 hours

i.e  The charge between 6 pm to 9 pm = $6.75

Again

After 9 pm , charges = $2.75 per hour

The time spend between 9 pm to 11 pm = 2 hours

So, The charge between 9 pm to 11 pm = $2.75 per hours × 2 hours

i.e  The charge between 9 pm to 11 pm = $5.5

So, The Total earning of Paula riddle from 6 pm to 11 pm =  charge between 6 pm to 9 pm + charge between 9 pm to 11 pm

i.e A = $6.75 + $5.5

Or, A = $7.25

So, The Total earning of Paula riddle from 6 pm to 11 pm = A = $7.25

Hence, The Total earning of Paula riddle from 6 pm to 11 pm is $7.25  Answer

Step-by-step explanation:

Let

y ---> the distance in miles    

x ---> the time in minutes

Remember that

[tex]1\ h=60\ min[/tex]

[tex]766\frac{2}{3}\ mi=\frac{766*3+2}{3}=\frac{2,300}{3}\ mi[/tex]

we have the ordered pairs

[tex](20,\frac{2,300}{3}),(60,2,300)[/tex]

Find the slope

[tex]m=(2,300-\frac{2,300}{3})/(60-20)[/tex]

[tex]m=(\frac{4,600}{3})/(40)[/tex]

[tex]m=\frac{4,600}{120}\\\\m=\frac{115}{3}\ mi/min[/tex]  

Find the linear equation in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{115}{3}[/tex]

[tex]point\ (60,2,300)[/tex]

substitute

[tex]y-2,300=\frac{115}{3}(x-60)[/tex]

[tex]y-2,300=\frac{115}{3}x-2,300\\\\y=\frac{115}{3}x[/tex]

Is a proportional relationship between the variables x and y (speed)

For y=1,150 miles

substitute the value of y in the linear equation and solve for x

[tex]1,150=\frac{115}{3}x\\\\x=1,150(3)/115\\\\x=30\ minutes[/tex]

Final answer:

It takes approximately 30 minutes for the shadow to travel 1,150 miles during a solar eclipse.

Explanation:

To determine the time it takes for the shadow to travel 1,150 miles, we can set up a proportion using the given information. Let's call the time it takes to travel 1,150 miles 't'. We can set up the proportion:

766.67 miles / 20 minutes = 1,150 miles / t

Now, let's solve for 't'. We can cross-multiply:

766.67 * t = 20 * 1,150

Divide both sides by 766.67:

t = (20 * 1,150) / 766.67

Simplifying the right side of the equation gives us:

t ≈ 30

Therefore, it takes approximately 30 minutes for the shadow to travel 1,150 miles.

Answer:

25 feet

Step-by-step explanation:

In this problem, you would need to use the pythagorean theorem, a^2 + b^2 = c^2.

It doesn't matter which you decide to be a and which you decide to be b, but the diagonal line, or hypotenuse, must be c. In this case, that is the ladder.

Now you plug numbers into the equation. 20^2 + 15^2 = c^2.

Simplify the left side of the equation. 400 + 225 = c^2, 625 = c^2.

Now, since c is still squared, take the square root of both sides. c = 25.

Another way to solve this is using the special triangles. One of the easiest to remember is the 3-4-5 triangle. That is what this triangle is, once you factor out a 5 from all of the numbers (15/5=3, 20/5=4, 25/5=5). Them you just multiply whatever missing number you are looking for by the factor you took out (5 × 5 = 25).

Answer:

The equation y = 3x represents a proportional relationship, where y represents distance in miles, and x represents time in hours. The point (3, 9) represents that Alonso walks 9 miles in 3 hours. The point (5, 15) represents that Alonso walks 15 miles in 5 hours.

The graph of line y = 3x represents how much distance is covered in how much time.

Here x is the time and y represents distance traveled. So, for points (3, 9) and (5, 15), it represents that Alonso covered 9 units of distance in 3 units of time and 15 units of distance in 5 units of time.

The general equation of line is,

y = mx + c

where m is the slope and c is the intercept.

Now the given equation is,

y = 3x

This represents Alonso's walking speed.

So it is explained that y distance is covered in x time.

Hence for points (3,9),

x = 3

y = 9

So,

Alonso covered 9 units of distance in 3 units of time.

For point (5,15)

x = 5

y = 15

So,

Alonso covered 15 units of distance in 5 units of time.

Thus,for points (3, 9) and (5, 15), it represents that Alonso covered 9 units of distance in 3 units of time and 15 units of distance in 5 units of time.
