Answer:
Solution,
length(l)=27km
Area(A)=212km²
Now As we have,
Area=lxb
212km²=27kmxb
b=212km²/27km
b=7.85km
Step-by-step explanation:
Since we have to divide the area by length to get the width. So, option C is correct.
Using proportions, it is found that the expression that tells how much greater the basketball score difference was on Wednesday than on Thursday is:

<h3>What is a proportion?</h3>
A proportion is a <u>fraction of total amount.</u> Then, to find how much greater an amount a is compared to an amount b, the expression is
.
In this problem:
- The difference of scores on Wednesday is of 68 - 54 = 14.
- On Thursday, it is of 59 - 48 = 11.
Hence, the expression that tells how much greater the basketball score difference was on Wednesday than on Thursday is:

Answer:
(d) 1 mile = 10 blocks
Step-by-step explanation:
The ballpark is 8 blocks west and 15 blocks north of Jeff's home. The Pythagorean theorem tells us the straight-line distance is ...
d² = 8² +15² = 64 +225 = 289
d = √289 = 17 . . . blocks
The problem tells us this represents 1.7 miles, so the proportion is ...
blocks/miles = 17 blocks/(1.7 miles) = 10 blocks/mile
The map scale is 1 mile = 10 blocks.
