Answer:

x=2

Step-by-step explanation:

Sense this is an isosceles trapezoid (side lengths are congruent) opposite angles (85 and 44x+7) are supplementary (add up to 180 degrees).

85+44x+7=180

Combine like terms.

44x+92=180

Do inverse operations (First, Subtract 92 from each side of the equation.)

44x=88

Then, divide 44 from both sides to solve for x.

x=2

Anisha invested $8,000 in an account that earns 10% interest How much money will she have in 15 years of the interest is compoun

tamaranim1 [39]

Answer:

A = $35,198.32

Step-by-step explanation:

Use the formula to calculate compound interest:

A = P(1 + i)ⁿ

"A" for total amount after the time period

"P" for principal, or starting money

"i" for the interest rate in a compounding period

To calculate "i":

i = r / c

"n" for the number of compounding periods

To calculate "n":

n = tc

So, we can combine the formulas into:

$A = P(1+\frac{r}{c})^{tc}$

"c" is the compounding periods in a year. (quarterly = 4)

We know:

P = 8000

r = 10% / 100 = 0.1

t = 15

c = 4

Substitute the information in the formula.

$A = P(1+\frac{r}{c})^{tc}$

$A = 8000(1+\frac{0.1}{4})^{15*4}$ Solve "i" and "n"

$A = 8000(1+0.025)^{60}$ Solve inside the brackets

$A = 8000(1.025)^{60}$ Do the exponent before multiplying by 8000

A = 35198.318 Exact answer

A ≈ 35198.32 Round to two decimal places for money

Therefore she will have $35,198.32 after 15 years.

A dad spends the same amount of time each week helping with homework. In 6 weeks, he spends 132 minutes. Write an equation that

pentagon [3]

Answer: f(x) = 22x

Step-by-step explanation:

1.) Divide 132 by 6 weeks, to get the amount of time spent each week on homework.

132 / 6 = 22

2.) Create the equation. Because x represents the number of weeks and 22 minutes a week is spent on homework, the equation is as follows:

f(x) = 22x

Janice is 4 inches shorter than David, and David is 2 inches shorter than Evan. If Evan is 13 inches taller than Kathleen and Ka

Sergeeva-Olga [200]

Answer: Janice is 1 inch taller than Krysta.

Step-by-step explanation:

Let the height of Krysta denoted by h .

According to the given statements , we will write height of each person in terms of 'h'.

Kathleen is 6 inches shorter than Krysta.

i.e. Height of Kathleen = h-6

Evan is 13 inches taller than Kathleen.

i.e. Height of Evan = (h-6)+13=h-6+13=h+7

i.e. Height of Evan =h+7

David is 2 inches shorter than Evan.

i.e. Height of David = (h+7)-2 =h+7-2

Height of David =h+5

Janice is 4 inches shorter than David.

i.e. Height of Janice= (h+5)-4=h+1

i.e. height of Janice = height of Krysta+ 1 inch [∵ h= height of Krysta]

⇒ Janice is 1 inch taller than Krysta.
