Answer:
Step-by-step explanation:
g(5) = 5^2 - 4 = 25 - 4 = 21
f(21) = 5(21) + 2 = 105 + 2 = 107
A=p(1+r/100)^n
A=2500(1+4/400)^16
A=2931.45
804 * 219 = 176,076
3674 * 89 = 326,986
4321 * 96 = 414,816
6782 divided by 5 = 1356.4
3224 divided by 96 = 33.58
3224 divided by 8 = 403
Answer:
3rd choice 0.57
Step-by-step explanation:
when rounding to the tenth place we look at the hundreds place and when it greater than or at 5 we round up and when it's less than 5 we round down.
1) explanation:0.7 when rounding to the tenth place. since the 8 was greater than 5 we round-up and get 0.70.
2)explanation: 0.5 when rounded to the tenth place the hundreds place which is 2 is less the 5 so we round down and get 0.50.
3)explanation: 0.6 when rounded its hundreds place is greater than 5 so we round up and get 0.60.
4)explanation: 0.7 when rounding to the tenth place. since the 9 was greater than 5 we round-up and get 0.70.

Answer:
Number of dimes = 16
Number of quarters = 17
====================================================
Work Shown:
d = number of dimes
q = number of quarters
d+q = 33 coins total, this solves to d = 33-q
10d = value of all the dimes in cents
25q = value of all the quarters in cents
10d+25q = 585 cents total
--------------
Plug in d = 33-q and solve for q
10d+25q = 585
10(33-q) + 25q = 585
330-10q+25q = 585
15q+330 = 585
15q = 585-330
15q = 255
q = 255/15
q = 17
The man has 17 quarters
d = 33-q = 33-17 = 16
He also has 16 dimes.
--------------
Check:
16 dimes + 17 quarters = 33 coins total
16 dimes = 16*10 = 160 cents
17 quarters = 17*25 = 425 cents
160 cents + 425 cents = 585 cents
The answer is confirmed.
