Christopher's backyard is in the shape of a trapezoid. The bases of the backyard are 30 and 50 feet long. The area of the backyard is 960 square feet. Write and solve an equation to find the height of Christopher's backyard. =12(1+2)ℎ
Answers
Answer:
24 feet
Step-by-step explanation:
The formula for the height of a trapezoid =
h = 2A/ a + b
A = 960 square feet
a = 30 feet
b = 50 feet
h = 2 × 960/30 + 50
h = 1920/80
h = 24 feet

Find the percent of change in the time to run a
mile from June to September. Round to the
nearest tenth of a percent. (Hint, make sure
change each to seconds first!)
7:45
(5:57
June
September
Answers
Answer:
23.225%
Step-by-step explanation:
Runtime in June (x1) = 7:45 = (7 * 60) + 45 = 465
Runtime in September (x2) = 5:57 = (5*60)+57 = 357
Percentage change in Runtime :
[|x2 - x1|÷ x1] * 100%
[|357 - 465| ÷ 357] * 100%
108 / 465 * 100%
0.23225 * 100%
= 23.225%

Guide Questions:
1. How do you saive for the area of the shaded region in figure A?
2. How do you solve for the area of the shaded region in figure B?
3. Is method finding the shaded region in figure A and B the same? Why? or Why not?
please answer on 3 i need answers for that number 3 questions
Answers
Answer:
1. The area is found by using the formula for a rectangle
The area is 150 cm²
2. The area is found by the definite integral for the area between two points under a curve
3. The methods are different
The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points
Step-by-step explanation:
1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure
From the question, we have;
The area of the rectangular figure, A = Length × Breadth
The length of the figure = 15 cm
The breadth of the rectangular figure = 10 cm
Therefore, we have;
A = 15 cm × 10 cm = 150 cm²
The area of the rectangular figure, A = 150 cm²
2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;
[tex]f(x) = e^{-t^2}[/tex]
Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]
Using a graphing calculator, we have;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]
3. The method of finding the area of figure A is different from the method of finding the area of the figure B
The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

Answers
Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals
0=0
