Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,

How many baseballs were pitched to Chad in that time?
Answer:
56 baseball's
Step-by-step explanation:
The number of baseballs were pitched to Chad in 8 minutes is 56.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Number of pitches hit in 1 minute = 35/5
= 7
Chad practiced hitting for 8 minutes.
So, the number of baseballs were pitched = 7×8
= 56
Hence, the number of baseballs were pitched to Chad in 8 minutes is 56.
