The price of the shoe pair in us dollars will be $50. The correct option is C.
<h3>What is unit conversion?</h3>
Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
It is given that shoes sell for 400 Hong Kong dollars in Hong Kong and the exchange rate is $0.125 per Hong Kong dollar. The cost of the same shoes in the united states will be calculated as below:-
Cost of shoes in the US = Cost in Hongkong x Exchange rate
Cost of shoes in the US = 400 x 0.125
Cost of shoes in the US = $50
Therefore, the price of the shoe pair in us dollars will be $50. The correct option is C.

The first question 10 and the next one is 40 the next one is 30
Answer ↣ 12 gallons per minute
Step-by-step explanation ↣ Ok I'm gonna use ratios because I can't draw a graph here.
Ok so if the garden hose supplies 36 gallons of water in 3 minutes, then the ratio is 36:3 because every 3 minutes the garden hose "sprays" 36 gallons.
To simplify this ratio, you need find the amount of water the garden hose supplies in 1 minute.
Well to get from 3 to 1, you have to divide by 3.
Do the same thing to 36. 36/3 equals 12.
So the final ratio is 12:1
This is the unit rate. The unit rate is when one variable is 1 unit (most of the time it is speed).
You can multiply 1 by any number and multiply 12 by the same number.
Here are some ratios...
m=minutes
g=gallons
1m:12g
2m:24g
3m:36g
4m:48g
5m:60g
Hope this helped!

B(cone)=B(pyramid)=r²π
V(pyramid)=1/3 * B * H = 1/3 * r² π * 3 r ( 3 will cancel out )= r³ π
Answer: r³ π
