Answer:

66°

Step-by-step explanation:

Because the two angles are vertical, this means they are opposite each other ergo they are the same size.

This means we can write the question like:

m∠A = m∠B

8x + 14 = 2x + 50

Step 1 - Subtract 14 from each side:

8x + 14 - 14 = 2x + 50 - 14

8x = 2x + 36

Step 2 - Subtract 2x from each side:

8x - 2x = 2x + 36 - 2x

6x = 36

Step 3 - Divide both sides of the equation by 6:

$\frac{6x}{6} = \frac{36}{6}$

Which simplifies to:

x = 6

m∠B = 2x + 50 so substitute in the solved x:

2(6) + 50 = 66

So m∠B = 66°

Hope this helps!

Hello!

Answer: ⇒⇒⇒⇒⇒⇒⇒ =54

_________________________________________________________________

Step-by-step explanation:

First you had to convert element to fraction.

$\frac{2}{3}*\frac{81}{1}$

Then you had to cross out by the common factor of 3.

$\frac{2}{1}=\frac{27}{1}$

Multiply by the fraction.

$\frac{2*27}{1*1}$

Multiply by the number.

$2*27=54$

$=\frac{54}{1*1}$

Again multiply by the number.

$1*1=1$

$=\frac{54}{1}$

Apply rule.

$\frac{54}{1}=54$

54 is the right answer.

A CD usually sells for $17.00. If the CD is 30% off, and sales tax is 8%, what is the total price of the CD, including tax?

Mademuasel [1]

Answer:

First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)

Multiply the original cost by 70%:

17.00 x 0.70 = $11.90 ( sale price)

Now you need to multiply the sale price by the tax percentage to find the amount of tax:

11.90 x 0.08 = 0.95 ( tax)

Now add the sale price and the tax for the total cost:

11.90 + 0.95 = $12.85

Molly Invests $8,600 into her son's college fund, which earns 3% annual interest

8_murik_8 [283]

Answer:

n= 13.8 years

Step-by-step explanation:

First, we need to determine the daily interest rate:

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

Now, using the following formula we can determine the number of days and years:

n= ln(FV/PV) / ln(1+i)

n= ln(13,000 / 8,600) / ln(1.000082)

n= 5,039 days

In years:

n= 5,039/365

n= 13.8 years
