Option B: The area of the trapezoid is 157.5 m²

Explanation:

We need to determine the area of the trapezoid.

The area of the trapezoid can be determined by the formula,

Area=\frac{h}{2} (a+b)

where h is the height, a and b are the base of the trapezoid.

From the figure, it is obvious that a=14 , b=7 and h=15

Substituting these values in the formula, we have,

Area=\frac{15}{2} (14+7)

Simplifying the terms, we have,

Area=\frac{15}{2} (21)

Multiplying the terms in the numerator, we have,

Area=\frac{315}{2}

Dividing, we get,

Area= 157.5 \ m^2

Thus, the area of the trapezoid is 157.5 m²

Hence, Option B is the correct answer.

Use mental math to approximate what a 15% tip would be for a bill of $31.99.
rodikova [14]

The whole bill is $31.99 that is 100%. You can use mental math to determine exatcly 15% from $31.99:

1. 15%=10%+5%

2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.

3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.

4. 15% from $31.99 is $3.199+$1.5995=$4.7985≈$4.80.

Answer: correct choice is B.

Sarah bought a $320000 house. She pays 20% down and takes out a 30-year loan for the rest. How much is the loan amount going to
lana [24]
The first thing you do is mutitpy 320,000 by .20 so that you can find the amount of down payment. The down payment would be 64,000. So you subtract 64,000 from 320,000. This leaves a loan amount of 256,000 dollars. The answer is 256,000 dollars .
