Answer:

Answer:

x=10

Step-by-step explanation:

In order to solve this equation we must break it down. This question is going to require the Pythagorean theorem a^(2) +b^(2)=c^(2). To use this we need a right triangle which happens to be half of the triangle shown. Now we can plug in the numbers.

7^(2)+(1)/(2) x^(2) =√(74)^(2)

49+(1)/(2) x^(2) =74

(1)/(2) x^(2) =25

(1)/(2) x=5

x=10

This ends in x equaling 10. I hope this helps you!

Mai invested $7000 in a money-market fund that paid 6.2% simple interest . What was the value of her account at the end of 18 months?

Answers

The formula of simple interest is: I=PRT
Where:
I stands for Interest
P stands for Price (or Principle Amount)
R stands for Rate
T stands for Time (in years)
I=PRT
 =7000×0.062×1.5  
         (6.2%=(6.2)/(100)=0.062)
          (18 months=12 months and 6 months=1.5 year)   
 =$651
$7000+$651=$7651
By the end of 18 months, Mai has $7651 in her account
Depends it could be 14812 if they want total value or just the interest would be 7812

Simplify the expression. 3 + 2 • (–8) A. –40 B. 40 C. 13 D. –13 Please help me

Answers

We need to follow PEMDAS.

We need to do the multiplication before we can do the addition (which becomes subtraction because of the sign).

3 + 2 • (–8)

3 + (-16)

3 - 16

-13

Your answer is D. -13

\huge\text{Hey there!}
