Jeremy is opening a savings account earning simple interest. He plans to deposit his $50 birthday money and leave the account alone until he goes to college. He will earn $5 per year in interest.

Answers

Answer 1
Answer:

Answer:

10%

Step-by-step explanation:

Use the formula of simple interest:

A=P(1+rt)

We can determine the interest rate if he earns $5 a year. Which means after a year he will have $55. Let A be the final amount after year t with t=1:

55=50(1+r(1))

Solve for r, the interest rate:

5=50r

r=5/50=0.1

Jeremy will earn money in the firsts year at a interest rate of 10%

there are 765 marbles in a in a box. there are twice as many blue marbles as green marbles. there are 3 times as many red marbles as blue marbles, how many red marbles in the box

Answers

let the no. of green marbles be x
no of blue marbles = 2x
no of red marbles = 3*2x = 6x
total marbles = 765
so, x+2x+6x = 765
or, x = 765/9 = 85
no of red marbles = 6*85 = 510

What is 1.8r+9=-5.7r-6

Answers

You could do:
1 subtract 9 on both sides of the equation, 1.8r=-5.7r-15
2 then add 5.7r on both sides as well, 7.5r=15
3 divide 7.5 on each side, r=2.
Add 6 to booth sides.

1.8r+15=5.7r
Subtract 1.8 from both sides
15=3.9r
Divide 15 by 3.9
3.8=r
