Answer:

Step-by-step explanation:
Assuming the given logarithmic equation is

We interchange x and y to get:

We solve for y now:

We add 4 to both sides to get;

Divide through by 4:

Answer: She will loose 75 min. (1 hour and 15 minutes)
Step-by-step explanation:
It is 72 1/10. This is because 72 is a whole number and point one would be tenths.
Answer:
revolutions per minute for 16 inches is 946 / minute
revolutions per minute for 14 inches is 1081 / minute
Step-by-step explanation:
Given data
radius = 16 inch
speed = 90 mph = 90/60 = 1.5 miles/minute = 1.5 × 5280 feet /12 inches = 95040 inches /minute
radius 2 = 14 inches
to find out
revolutions per minute
solution
first we calculate the circumference of the wheel i.e. 2×
×radius
circumference = 2×
×16
circumference = 32
we know that revolution is speed / circumference
revolution = 95040/32
revolution = 945.38 / minute
we have given radius 14 inches than revolution will be i.e.
revolution = speed / circumference
circumference = 2×
×14
circumference = 28
revolution = 95040/ 28
revolution = 1080.43 / minute
170^3 this is the answer just make sure you do you're work.
