16•0.10= 1.60$
8•0.05= 0.40¢
12•0.25= 3.00$
1.60$+0.40¢+3.00$= 5.00$
3•0.10= 0.30¢
5•0.05= 0.25¢
0.30¢+0.25¢= 0.55¢
5.00$-0.55¢= 4.45$
4.45$ is left in the piggy bank.
Answer:
C(n, 2)a^(n-2)b^2
Step-by-step explanation:
Generally, the expansion is written in decreasing powers of "a", so the first few terms would have variable constellations that look like ...
a^n, a^(n-1)b, a^(n-2)b^2, ...
The coefficients would be (in order), C(n, k) for k increasing from 0, so the coefficient of the 3rd term would be C(n, 2).
Answer:
The fence will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = perimeter of semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of 1 foot of fence
45.53 * $7.25 = 330.0925
Rounding to the nearest hundredth
$330.0925 = $330.09
