I think it should be 31.5
6 builders over 21 days would be equal to 9 builders over X days. Then you would cross multiply
The real distance between the two cities is 100000 feet.
<h3>How to use scales to estimate real life distances</h3>
Scales are applications of ratios in which maps are mostly based and that are used to estimate real distances between two points. Scales (r) are represented by the following formula:
r = m' / m (1)
Where:
- m - Real length
- m' - Reduced length
If we know that m' = 400 in and r = 4 in / 1000 ft, then the real distance between the two cities is:
m = m' / r
m = (400 in) / (4 in / 1000 ft)
m = 100000 ft
The real distance between the two cities is 100000 feet.

Answer:
<h2>21/32</h2>
Step-by-step explanation:
-7/8 × -3/4 = 21/32
-7 × -3 = 21
-8 × -4 = 32
21/32
<u><em>IMPORTANT: This number is not negative, because a negative times a negative is a positive.</em></u>
By the way, if you didn't know how to arrive at the fraction here's how.
First, Address input parameters & values.
Input parameters & values: The decimal number = 0.65625. Then, write it as a fraction
0.65625/1
Multiply by 100000 both the numerator & denominator
(0.65625 x 100000)/(1 x 100000) = 65625/100000
65.625% = 65.625/100 or 65625/100000
Find LCM (Least Common Multiple) for 65625 & 100000.
3125 is the LCM for 65625 & 100000
Divide by 3125
65625/100000 = (65625 / 3125) / (100000 / 3125)
= 21/32
I'm always happy to help :)
Answer:
14π
Step-by-step explanation:
The equation for circumference is
C = π* diameter
AB is the diameter, so the circumference is 14π
