Hello!

<em><u>REVIEW
</u></em>Perimeter is the distance around a shape. To calculate perimeter, you do: 2l + 2w

Area is calculated by multiplying the length and width together.

<em><u>Perimeter</u></em>

The length is 7. 2l = 2 × 7 = 14
The width is 4. 2w = 2 × 4 = 8

<em>Add together</em>

14 + 8 = 22

\framebox{The perimeter is 22 feet}

<em><u>Area

</u></em>The length is 7, and the width is 4.

7 × 4 = 28

\framebox {The area is 28 feet}

Formula for P:  P = 2W + 2L
Formula for A:  A = WL

Here, P = 2(4 ft) + 2(7 ft) = (8+14) ft = 22 ft
and    A = (4 ft)(7 ft) = 28 ft^2

Flura [38]

Answer:

Angle, \theta=70.4^{\circ}

Step-by-step explanation:

We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.

The attached figure shows the A frame. Let \theta is the angle that the roof makes with the floor. So,

\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}

So, the angle of 70.4 degrees is the angle that the roof makes with the floor.

Umnica [9.8K]

Answer:

The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20

Step-by-step explanation:

Given as :

The total amount spend for soup = $ 20

The cost of Tomatoes = $ 2.50 per pound

The cost of Red peppers = $ 4 per pound

Let the quantity of tomatoes to be bought = T pound

The quantity of red peppers to be bought = R pound

So, According to question

$ 2.50 × T + $ 4 × R = $ 20

I.e The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20   . Answer

Help! i need to answer this before 11:59pm EST, Today !!, i would appreciate your help.
Arada [10]

Answer:

0.18 sec or 3.4 sec.

For second part, it will take 3.7 sec.

First part:

Set h(t) = 17and solve for t.

-16t²+ 58t + 7= 17

-16t² + 58t - 10 = 0

Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.

Second part:

Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
