$ 524.288
Step-by-step explanation:
We will use the sum of a geometric series;
S = (first term)(1-r^n)/(1-r)
= 1(1 - 2^n) / (1 - 2)
= - (1 - 2^n)
= 2^n - 1
2 ^ (20 – 1)
2 ^ 19
= 524,288 cents
100 cents = 1 dollar
524,288 cents = 524,288/ 100 dollars
= $ 524.288
Answer:
C AAA is not an accepted triangle congruence criterion
Step-by-step explanation:
AAA can be used to show similarity, but not congruence. At least one side must be involved in any triangle congruence claim.
__
The student could have made use of the fact that opposite sides are the same length, and used AAS or ASA to show congruence.
The item us going to cost 4.975
just convert the percent to decimal by moving the decimal point two spaces to the left and multiply it times the price and it will give you the discount the subtract the discount from original price and the result will be the new price.
99.50x.95=94.525
99.50- 94.55=4.975
you can round it up to 4.97
Answer:
No
Step-by-step explanation:
The ratio of length to width in the first is 2 : 1 while the ratio of the second is 23 : 19
Answer:
A = 2000(1.04)^t
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
P is the principal = $2000
r is the rate = 4% = 0.04
On substituting
A = 2000(1+0.04)^t
A = 2000(1.04)^t
Hence the required expression is A = 2000(1.04)^t
