Answer:

c. 105 yd^2.

Step-by-step explanation:

First find the slant height (h) of each of the triangular walls:

tan 60 = h /  3.1

h = 3.1 tan 60

= 5.369 yds.

Area of each side = 3.1* 5.369

= 16.645

Total surface area of the pyramid

= 4 * 16.645 + 6.2^2

= 105.02 yd^2.

A person standing close to the edge on top of a 72-foot building throws a ball vertically upward. The quadratic function h(t)=−1
aleksklad [387]

The quadratic function h(t) = −16t² + 84t + 72, shows that the person throws the ball from on top of a 72 feet building at a velocity of 84 feet/second.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

A cube has a volume of 64. What is the length of one side of the cube?
bearhunter [10]

Answer:

4

Step-by-step explanation:

The volume of a cube can be represented as s^3 = v, where s = side and v = volume. In this case, we're given the volume as 64, so s^3 = 64. To solve this problem, we first have to know what a cube root is.

What's a cube root?

  • The cube root of a number is the number you multiply by itself 3 times to get another number.
  • One common cube is 27, and the cube root of it is 3 because 3 x 3 x 3 = 27.

Given the information above, let's go in order with the list of cube roots to see which one has a cube of 64.

  • 1: 1 x 1 x 1 = 1.
  • 2: 2 x 2 x 2 = 8.
  • 3: 3 x 3 x 3 = 27.
  • 4: 4 x 4 x 4 = 64. (This is the cube root!)

We found the cube root of 64, or the side of the cube with a volume of 64. The side of the cube, therefore, is 4.

Plz help I need bt tonight

The answer is 25%.

First: work out the difference between the two numbers you are comparing.  

Decrease = Original Number - New Number

35-28=7


Then: divide the decrease by the original number and multiply the answer by 100.  % Decrease = Decrease ÷ Original Number × 100


7÷

28=.25

.25*100=25
