fifty five hundredths is equal to 0.55
Multiply each exponent inside the parentheses by the exponent on the outside:
8^(-5 x -4) / 2^(-2 x -4)
8^20 / 2^8
The answer is C

1= hour
x= how many hours
8= miles
Answer:
110 yards of string
Step-by-step explanation:
Converting the feet of the string of 1 balloon to yard
1 foot = 1/3 yard
6 feet = x
x = 6 × 1/3 yard
x = 2 yard
Hence 1 balloon uses 2 yard of string
Since:
1 balloon = 2 yard of string
55 ballons = x
x = 55 × 2 yard of string
x = 110 yards of string
Hence, for 55 balloons he would need 110 yards of string.
1-
number 2) is correct
2- 3) is true
11) Jacob is not correct. because 6radical 5 is irrational
12) radical 20 is an irrational number but
so a+b is irrational
but
so b+c is rational
good luck
