I think the answer is 140, because in the question is asked twice angle R, so I multiplied 70 x 2= 140.
Answer= 140
Hope this helps!!
and sorry if I get it wrong
Answer:
(a) There is $1740.88 in Mary's account after 2 years
(b) The interest earned on Mary's investment after 2 years is $40.88
Step-by-step explanation:
Let us revise the rule of the compound interest
→
, where
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
∵ She invested $1700
∴ P = 1700
∵ The rate is 1.19%
∴ r = 1.19/100 = 0.0119
∵ It is compounded quarterly
∴ n = 4
∵ She decided to invest her money for 2 years
∴ t = 2
Let us substitute these values in the rule above to find her new amount of money in her account
→ 
→ 
→
dollars
Round it to the nearest cent → means 2 decimal places
→ A = $1740.88
(a) There is $1740.88 in Mary's account after 2 years
The interest amount is the difference between the new amount and the initial amount

∵ P = 1700
∵ A = 1740.88
∴ 
∴ I = $40.88
(b) The interest earned on Mary's investment after 2 years is $40.88
Answer 8 kids, 8 jolly ranchers each, 7 lolipops each
Step-by-step explanation:
3:4 is the answer. Look at it like a pattern. 9:12, 3 goes into both of them, 12:15, 3 goes into both of them, 12:16, 4 goes into both of them. However nothing goes into both the numbers in 3:4.
The width is 50 in
If the length is 77 in, multiply that by 2 for both lengths and you get 154 in.
Then subtract that from 254 and you get 100, which is the 2 widths.
For one side’s width, divide 100 by 2 and the answer is 50 in.
