Three friends were born in consecutive years. The some of their birth years is 5982.find the year in which each person was born

Answers

Because the three numbers are consecutive, if the first one is x, the second should be x+1, and the third one is x+2
the three numbers add up to be 5982, so
x+(x+1)+(x+2)=5982
3x+3=5982
3x=5979
x=1993
1993,1994,1995

Answer:

The birth years of first person is 1993.

The birth years of second person is 1994.

The birth years of third person is 1995.

Step-by-step explanation:

Three friends were born in consecutive years

Let the birth years of first person be  x,

Let the birth years of second person be (x+1)

Let the birth years of third person be(x+2)

The sum of their birth years is 5982.

[tex]x+(x+1)=(x+2)=5982[/tex]

Solving the given equation for x:

[tex]3x+3=5982[/tex]

[tex]x=\frac{5982-3}{3}=1993[/tex]

The birth years of first person = x =  1993

The birth years of second person = (x+1) = 1993+ 1 = 1994

The birth years of third person = (x+2) = 1993+2 = 1995

A car travels 416 miles in 8 hours and at this rate how many miles will the car travel in 22 hours

Answers

Divide the miles by the hours to get the rate. 

416miles/8hrs = 52miles per hour

So, 22 hours at 52mph (22*55) = 1210 miles.

In 22 hours the car will have gone 1210 miles.

To find out how many miles the car will travel in 22 hours, we calculate the unit rate by dividing 416 miles by 8 hours to get 52 miles per hour and then multiply this unit rate by 22 hours to get 1144 miles

The question involves calculating the distance a car will travel at a given rate over a different period of time. This is a basic rate problem in math, often approached by finding the unit rate and then scaling it to the desired time.

Step 1: Identify the rate of travel. The car travels 416 miles in 8 hours.

Step 2: Find the unit rate by dividing the distance by the time. Unit rate = 416 miles / 8 hours = 52 miles per hour.

Step 3: Calculate the distance the car will travel in 22 hours using the unit rate. Distance = 52 miles/hour * 22 hours = 1144 miles.

So, at this rate, the car will travel 1144 miles in 22 hours

Answers

Hello Highkay7527, I suspect you may have stated the problem incorrectly; it is possible to get the angles that result from the calculations;
The total of all the angles in a triangle is 180 degrees.
1x +3x +x - 35 = 180.
5x = 215.

The steps to do it. It says "solve for x. Each figure is a parallelogram. Show your work.

Answers

So in a parallelogram, the angles on the same side (i.e. G & F or G & D) will always add up to 180 so to solve this problem you would set up the equation 140+10x=180 then solve for x.

The value of x is 4.


To solve for x, we'll use the property of parallelograms that opposite angles are supplementary.

Given that one angle is [tex]\(140^\circ\)[/tex], we can set up the equation:

140 + 10x = 180

Now let's solve for x:

10x = 180 - 140

10x = 40

[tex]x = \frac{40}{10}[/tex]

x = 4

Therefore, the value of x is 4. Adjacent angles in a parallelogram are indeed supplementary.

Consider the equation below. f(x) = 4x3 + 6x2 − 24x + 3 (a) find the intervals on which f is increasing. (enter your answer using interval notation.)

Answers

Final answer:

The function f(x) = 4x^3 + 6x^2 - 24x + 3 is increasing on the interval (-2/3, 1.5), where the derivative of the function is positive.

Explanation:

To find the intervals on which the function f(x) = 4x^3 + 6x^2 − 24x + 3 is increasing, we first need to calculate its derivative, which will give us the slope of the tangent line to the function at any point x. The function is increasing wherever its derivative is positive.

The derivative of f with respect to x is:
f'(x) = 12x^2 + 12x - 24.

To find where the function is increasing, set the derivative greater than zero:

12x^2 + 12x - 24 > 0

Solve this inequality to find the intervals for x. Factoring the quadratic, we get:

(2x - 3)(6x + 4) > 0

The zeros of this equation are x = 1.5 and x = -2/3. These values divide the real number line into intervals. Test a value from each interval to see where the function is increasing:

If x < -2/3, for example x = -1, the derivative becomes negative, indicating the function is decreasing.If -2/3 < x < 1.5, for example x = 0, the derivative is positive, indicating the function is increasing.If x > 1.5, for example x = 2, the derivative is again negative, indicating the function is decreasing.

Thus, the function f(x) is increasing in the interval (-2/3, 1.5).

A hockey team played 81 games in a season. they won one fewer games than three times the number of ties, and lost eight fewer games than they won. how many games did they win? lose? tie?

Answers

Final answer:

The hockey team won 38 games, lost 30 games, and tied 13 games in the season.

Explanation:

Let's define the variables for the different outcomes in the hockey team's season:

T = number of games tiedW = number of games won = 3T - 1L = number of games lost = W - 8

The total number of games is the sum of wins, losses, and ties, and we know this number is 81. This gives us the equation:

W + L + T = 81

Substituting W and L gives:

(3T - 1) + (3T - 1 - 8) + T = 81

Combining like terms and solving for T:

7T - 10 = 81

7T = 91

T = 13 (number of ties)

We then calculate W and L as:

W = 3T - 1 = 3(13) - 1 = 38 (number of wins)

L = W - 8 = 38 - 8 = 30 (number of losses)

The pitch of the roof is the number of feet the roof rises for each 12 feet horizontally. If a roof has a pitch of 8. What is its slope expressed as a positive number? What does the slope mean in this story?

Answers

Refer to the diagram shown below.

The height is h ft
Half of the total horizontal base length is w ft.

Because the pitch is 8, therefore
When w = 12 ft, then h = 8 ft.
That is
w/h = 12/8
w = 1.5h

The slope is h/w = 8/12 = 2/3.
As an angle, 
θ = tan⁻¹ 2/3 = 33.7°

Answer:
Slope = 2/3.
The slope represents an angle of elevation of 33.7°.

Final answer:

The slope of the roof, expressed as a positive number, is 0.67. This represents the steepness of a roof, with a higher number indicating a steeper roof. The figure is calculated using the rise over run ratio.

Explanation:

The pitch of a roof is a number that expresses how much the roof's height changes for every 12 feet you move along horizontally. If a roof has a pitch of 8, it means that for every 12 feet you move horizontally, the height of the roof increases by 8 feet. This gives us a rise/run ratio, which is how slope is defined in mathematical terms.

In this case, the rise is 8 feet, and the run is 12 feet. So, the slope would be 8/12, or 0.67 when expressed as a positive decimal number.

The slope here represents the steepness of the roof. A higher slope means a steeper roof and vice versa. By expressing the slope as a number, we can get an idea of how steep the roof is without having to see it in person.

A local civic group is selling t-shirts to raise funds for Relay to Life. They plan to sell
2500 t-shirts for $10. They consider raising the t-shirt price in order to earn more

number of $1 increases.
a. Write a function,
Write a function, c(x), to represent the cost of one t-shirt based on the number
of increases.
b. Write a function, t(x), to represent the number of t-shirts sold based on the
number of increases.
c. Write a revenue function, r(x), for the t-shirt sell that could be used to maximize

Answers

a. Let us say that c(x) is the cost of one t shirt based on the number of increases therefore:

c = 10 + x

 

b. Say that t(x) is the number of t shirts sold based on the number of increases so:

 t = 2500 – 100 x

 

b. The revenue is simply the product:

r(x) = (10 + x) (2500 – 100 x)

 

Combining:

r(x) = 25000 – 1000 x + 2500 x – 100 x^2

r(x) = 25000 + 1500 x – 100 x^2

 

Taking the 1st derivative and setting dr / dx = 0 to get the maxima:

dr / dx = 1500 – 200 x

1500 = 200 x

x = 7.5

 

t = 2500 – 100 x = 2500 – 100 (7.5) = 1750

 

Hence 1750 shirts should be sold.

Answers

The formula for calculating area of rectangle is Area= Length (longer side of rectangle) * Breadth (shorter side of rectangle) We need to find length and breadth of rectangle by drawing rectangle on coordinate plane. Then we can count points between vertices that are opposite to each other Then we get length= 4 units and breadth=3 unit Then Area= 4 * 3= 12 units^2 we use unit because certain unit is not given I.e. cm , inch, metre etc
Final answer:

The area of the rectangle is 8 units².

Explanation:

To find the area of a rectangle, we can use the formula A = length * width. In this case, we can use the coordinates of the vertices to determine the length and width of the rectangle.

Using the distance formula, we can find the length between the points (-3, -1) and (1, 3) to be 4 units, and the width between the points (1, 3) and (3, 1) to be 2 units.

Therefore, the area of the rectangle is 4 * 2 = 8 units².
