Answer:

7:15 AM

Step-by-step explanation:

First, take 11 - 4 to give you 7. The 11 comes from the starting time, and the four comes from the four and a half hours.

Next, you'll take 45 - 30 to give you 15. Again, the 45 coming from 11:45 and the 30, or 1/2, coming from the four and a half hours before hand.

In the end, you'll get 7:15. Since the starting time was in the AM, and we are going back in time 4 1/2 hours, it will still be AM. So we add AM onto the end of the 7:15 to get your answer.

Hope this helps :)

You buy the same number of brushes, rollers, and paint cans. Write an expression in simplest form that represents the total amou

Soloha48 [4]

If you buy ' N ' of each item, then you'll pay 3.99N for brushes,
21.79N for cans of paint, and 6.89N for rollers.

The question assures us that you bought the same number of
each item. So your total bill at the hardware store checkout is

3.99N + 21.79N + 6.89N

= N (3.99 + 21.79 + 6.89)

= 32.67 N .

ben drives from a 36- foot platform. The equation h= -16t^2+14t+36 models the dive. How long will it take Ben to reach the water

Valentin [98]

So you want to plug in the height for h and solve for t

36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds

Hope this helped!

A tent forms an equilateral triangular prism, with both triangular faces exposed. each side of the triangular face has a length

Soloha48 [4]

Given:
Equilateral Triangular Prism
Each side of the triangular face has a length of 196cm
The tent is 250cm long

I have attached an image of the tent. Since the height of the tent is also the height of the triangle, I will solve for the height of the triangle using Pythagorean theorem.

I divided the equilateral triangle into 2 right triangle. The height then becomes the long leg of the triangle. The hypotenuse is 196cm and the short leg is 98cm, half of one side of the triangle.

a² + b² = c²
a² = c² - b²
a² = (196cm)² - (98cm)²
a² = 38,416cm² - 9,604cm²
a² = 28,812cm²
a = √28,812cm²
a = 169.74cm

The height of the tent is 169.74 centimeters.
