Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
If 3 =
, then we know 9 =
because 9 is 3 squared.
can be simplified to
So now we know
=
·
Since
and
have the same base, we can express it as a single term by adding the exponents together.
So the answer is C)
Answer:532 adult tickets were sold
Step-by-step explanation:591-59
X=6.75
3+x=5x-24 Add 24 on both sides
27+x=5x Subtract 1x on both sides
27=4x Divide 4 on both sides
6.75=x You Can double check by plugging in x
Step-by-step explanation:
5⁵ − 5⁴ + 5³
Factor 5³.
5³ (5² − 5 + 1)
5³ (25 − 5 + 1)
5³ (21)
21 is a multiple of 7, so 5⁵ − 5⁴ + 5³ is a multiple of 7.
