Gabriel wants to paint the model. How

enyata [817]

Answer:

<h2>The area of the base is 144 square inches.</h2><h2>The area of each triangular face is 66 square inches.</h2><h2>Grabiel needs 408 square inches of paint.</h2>

Step-by-step explanation:

The complete problem is attached.

Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of

$B=12 \times 12 = 144 \ in^{2}$

The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face

$A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}$

But there are four triangle faces, so $A_{faces} =4(66)=264 \ in^{2}$ .

Therefore, the area of each triangular face is 66 square inches.

So, the total surface area would be the sum

$S=144+264=408 \ in^{2}$

Therefore, Gabriel needs 408 square inches to paint the whole model.

Tpy6a [65]

Answer:

The balance after 15 year is $831.25 .

Step-by-step explanation:

Formula

Where P is the principle and r is the rate of interest in the decimal form and t is the time.

As given

Caiden earned $475 from mowing lawns last summer.

He deposited this money in an account that pays an interest rate of 3.8% compounded annually.

Here

P = $475

3.8% is written in the decimal form.

= 0.038

r = 0.038

t = 15 years

Put in the formula

Amount = $831.25

Therefore the balance after 15 year is $831.25 .

Answer:

(D) 112

Step-by-step explanation:

First step: Arrange all the numbers from in ascending order that is from smallest to largest.

In Ascending order the set becomes:

45,99,108,116,118,118,118,119,120,121,124,130,148.

Second step: Find the median of the set of numbers.

Median is the middle number.

The median is 118. The median is also called the second quartile(Q2).

Third step: Now we consider all the numbers to the Left of the median(Q2). The numbers are listed below:

45,99,108,116,118,118.

Now we will find the median of these numbers.

The total numbers are 6 which is an even number.

To find the median of an even number, we add the two middle numbers and divide them by 2.

The two middle numbers are 108 and 116.

Therefore 108+116 = 224.

224/2 =112.

Therefore 112 becomes the first quartile (Q1).
