Step-by-step explanation:
24*.15=3.6
200=2.5*speed
speed=80
1:1/12
x:48
576 in
35=.2*x
x=175
30*1.5=45
48*.065=3.12
.5*(2π*5)=15.7
15.7+6+10=31.7
24²+a²=26²
a²=100
a=10
Pretty sure it's just 36

Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
=
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
4 (5z+2y) (5z-2y) (Ignore this)
The answer should be -141
Step-by-step explanation:
year 2012 population = 2,254,000*3.5%
= 78.89
each year up to 2020
so 2020 - 2012 =8
78.89*8 = 631
total population at end of 2020 =2,254,000 + 631
= 2,254631
