therefore
9 × 475 = 9 × (400 +70 + 5) = 9 × 400 + 9 × 70 + 9 × 5
=3600 + 630 + 45 = 4275
I think... It's better to use Distributive Property:
(a - b) × c = a × c - b × c
9 = 10 - 1
therefore:
(10 - 1) ×475 = 10 × 475 - 1 × 475 = 4750 - 475 = 4275

What are ratios and proportions?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio surface area of toy A: to the surface area of toy B is 7:9. The volume of toy B is 20 cm
The computation of the volume of toy A is shown below:
7 × k²=9
k²= 9 ÷ 7
k=√(9 ÷ 7)
k = 1.133893419
Now
The volume of toy A = 20 ÷ 1.133893419³
The volume of toy A = 13.7 cubic centimetres
Therefore, the volume of toy A will be equal to 13.7 cubic centimetres.
The missing figure is attached with the answer below.

Answer:
13.7
Step-by-step explanation:
7*k²=9
k²=9/7
k=√9/7
k=1.133893419
20/1.133893419³=13.7

The fox will run at a faster speed than a rabbit.
What is a unit conversion?
Unit conversion is the process of changing a quantity's measurement between different units, usually using multiplicative conversion factors.
Given that a rabbit can run short distances at a rate of 35 miles per hour. A fox can run short distances at a rate of 21 miles per half hour.
Compare the speed of the rabbit and the fox as below,
Rabbit speed,
21 miles ⇒ 1/2 hour
21 x 2 miles ⇒ 1 hour
42 miles ⇒ 1 hour
Fox speed,
35 miles ⇒ 1 hour
The Fox will travel 42 miles in an hour than the rabbit.
Therefore, the fox will run at a faster speed than a rabbit.
To know more about unit conversion follow
#SPJ2
21 miles in 30 minutes= .7 of a mile per minute
if you multiply by 60 to see the distance in the same amount of time:
rabbit: 35 mph
fox: 42
So the fox would run a greater distance in the time given. Hope this helps!
