For this, we use the given info plus a bit of multiplying and subtraction

part 1)

we know that she's 25 y/m
so 5 minutes simply means 25 × 5
$25 \times 5 = 125 \: yards$

now we simply subtract this from 1000 (the original distance)
$1000 - 125 = 875 \: yards$

part 2)

the total time taken is even easier to find
all we have to do is divide 1000 by 25
$1000 \div 25 = 40 \: minutes$

A conical tent made of canvas has a base that is 34 feet across and a slant height of 12 feet. To the nearest whole unit, what i

tresset_1 [31]

Here you'll need to do some online research, using "area of a cone" as your search term. There is a formula! But it's complicated.

Once you've found this formula online, substitute 17 feet for r. The height of the cone has to be calculated from the slant height (these are not the same):

(slant height)^2 = (12 feet)^2 = r^2 + h^2, where h is the actual height of the cone.

The area of the base is pi*r^2, or pi*17^2 square feet.
