Answer:
Step-by-step explanation:
Easy 0.6 times 0.8 = 0.48
To answer the question above, determine the ratio between the their typing speed by dividing Jennifer's speed by Paul's. This is shown below,
r = 60 words per minute/ 80 words per minute
r = 3 / 4
Therefore, Paul's typing speed is 3/4 of Jennifer's speed. The answer is letter A.
Let's call the number you thought of n. Then what the two steps you took can be written as an equation:
Subtract n to get all of your variables to one side:
At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:
Now divide both sides by 11 to get the value of n:
A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.
Area of a circle: A = pi x r^2
r = 160 / 2 = 80
A = pi x 80^2
A = 6400pi / 2 = 3200pi
3200pi = 10053.0965
The area water is approximately 10,053 ft^2.
Hope this helps!! :)
Distance = rate X time
352 miles = rate X 5.5 hrs 30 minutes is half or .5
Divide both sides by 5.5
rate = 64 miles/hour
