Step-by-step explanation:
So first off we want to find out how many miles Nina can ride in 3,600
For this we have to convert 63,360 feet into miles
If there are 5,280 feet in one mile than we need to see how many times 5,280 goes in to 63,360
divide 63,360 by 5,280: you get 12
This means that she can bike 12 miles in 3,600 seconds
3,600 seconds is the same as an hour
Answer:
Nina can bike 12 miles per hour
Answer:
Step-by-step explanation:
Use the distance formula:
For us that will look like this:
which simplifies to
and a bit more to
so

Find the perimeter of the garden find out what kind of triangle the garden is for example if it is a right triangle it has to equal up to 90.
To find the area remember that A=b•h2 as a=area
Answer:
A. 15
Step-by-step explanation:
Answer:
x = 18
m∠HCB = 36
Step-by-step explanation:
The measure of angle FBC is 8x and the measure of angle HCB is 2x. If you add the measures of both angles it will equal to 180 degrees. This can be represented in an equation:
8x + 2x = 180
10x = 180
Divide both sides of the equation by 10 to isolate the x:
10x/10 = 180/10
x = 18
Now that we know the value of x, we can find the measure of angle HCB:
2x
2(18)
36
The measure of angle HCB is 36.
I hope this helps :)
