Answer:
There are 32 dimes and 25 quarters.
Step-by-step explanation:
q + d = 57 or q = 57 - d
25q + 10d = 945
substitute first equation into second equation:
25(57 - d) + 10d = 945
1425 - 25d + 10d = 945
-15d = -480
d = -480/-15 = 32
using first equation:
q = 57 - 32 = 25
check using second equation:
25(25) + 10(32) = 945 checks
13/8
But if you want it in decimal form it’s
1.625
Answer:
10x^3+14x^2-25x-35
Step-by-step explanation:
f(x) = 2x^2 -5
g(x)= 5x+7
f(g(x)) = (2x^2 -5)(5x+7)
5x(2x^2 -5)+7(2x^2 -5)
10x^3-25x+14x^2-35
10x^3+14x^2-25x-35
Answer: the distance between the two points in Decimal Form is 9.899
Answer:
The expression 1.02^(4+n) can be used because 1.02^4 * 1.02^2= 1.02^(4+n) AND this is option C.
Step-by-step explanation:
For 4 + N years = (1 + 2/100)^(4+N)
= 1.02 ^ (4+N)
Remember, that the number of years is increased by N and interest rate remain the same, and n is years, and which is now 4+ N.
