What is the area, in square inches, of the isosceles trapezoid below?

Komok [63]

A = 73.84

Explanation-

14.2 - 6.4 = 7.8 (to get the length of the base without the top part)

7.8 • 5.2 = 40.56 (to find the area outside of our subtracted square that has the top part)

6.4 • 5.2 = 33.28 (to find the area of the inner square)

40.56 + 33.28 = 73.84 (adding together both parts to find the total area)

A = 73.84

Triangle DEF, shown below, is reflected over the y-axis to form triangle D'E'F'. What are

vovikov84 [41]

Answer:

(-6, -4).

Step-by-step explanation:

When you reflect coordinates over the y-axis, the x-coordinates remain the same, but the y-coordinates become their additive inverse.

The original coordinates for F are (6, -4).

The new coordinates for F would be F' (-6, -4).

Sam invests $6000 in two different accounts. The first account paid 12 %, the second account paid 7 % in interest. At the end of

Lunna [17]

Answer:

The amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600

Step-by-step explanation:

Let x be the amount in the account at 12% interest

So, 6000-x is the amount in the second account at 7% interest

$SI = \frac{P \times T \times R}{100}$

First account: $SI=\frac{x \times 1 \times 12}{100}$

Second account : $SI =\frac{(6000-x) \times 1 \times 7}{100}$

We are given that At the end of the first year he had earned $590 in interest.

So, $\frac{x \times 1 \times 12}{100}+\frac{(6000-x) \times 1 \times 7}{100}=590\\x=3400$

So,the amount in the account at 12% interest is $3400

The amount in the second account at 7% interest =6000-x=6000-3400=2600

Hence the amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
