20/24

5/6

Answer:

they sleep for 20/24 percent of the day or 4.8 percent.

Step-by-step explanation:

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

Answer:

Trapezoid

Step-by-step explanation:

A triangle can be thought of as a trapezoid with one of the side length being 0.

Answer:

Parallelogram

Step-by-step explanation: "Surprisingly, this triangle (or any triangle) is related to a parallelogram." Found it in my text (Calvert Academy school)

Answer:

b=123

c=123

Step-by-step explanation:

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%

Answer:a) 34916  b) 411

Answer:

$100

Step-by-step explanation:

Multiply 250 by 2. Then, divide that by 5

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.

Answer:

Answer:

Step-by-step explanation:

please brainleist please

Answer:

A situation in which you would need to calculate the surface area or volume of a solid would be when you are going to put up wallpaper in a room. You need to measure the room and the wallpaper. If you wanted to put up moldings on the walls too, than you would need to measure the surface area and volume of the moldings as well so you would know where to cut the wood to fit witht eh wall shape of the room.

Step-by-step explanation:

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

Step-by-step explanation:

Answer:

CD= 4.25

Step-by-step explanation:

so CD is similar to RS

and the difference between the shapes are 3.75cm.

so 8 - 3.75 =4.25

Answer:

Step-by-step explanation:

Answer:

I belive it would be $17,600

Step-by-step explanation:

The way I did it might be confusing but.

12% of 8,000 is 960

960 * 10 is 9,600

9,600 + 8,000 = 17,600

Answer:

it is D
