So, this question is like finding the radius given the circumference.
Circumference is 113, and the formula to find the radius is $r = C/2 \pi$
$r = 113/2 \pi$

R ≈ 17.98
So, the most likely length of of the blade would be B) 18 inches.

The area of a square is 102 square units. What is an

Neko [114]

Answer:

Between 10 and 11.

Step-by-step explanation:

To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)

10²= 100

11²= 121

Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.

now, two lines who meet at a perpendicular angle, have a negative reciprocal slope of each other, to make it short, if you multiply their slopes, you should get -1 as the product, if they're indeed perpendicular.

$\bf \stackrel{PQ}{-\cfrac{4}{1}}\cdot \stackrel{QR}{\cfrac{1}{4}}\implies -1$

low and behold, they're indeed perpendicular, thus that angle is indeed a right-angle.

Find the AREA and PERIMETER of the triangle

poizon [28]

Area of triangle is 240sqft.

Find Area by multiplying the height(16ft) by the base(8ft+22ft=30ft), then divide by 2.

Perimeter is 80, just add all the side lengths together

Georgia [21]

The additive inverse of something is just what the certain number needs to equal 0. In this case 3+5=8 inches total. In order to get 8 inches to 0 you need to add -8 to 8. So the additive inverse is -8 inches (Always remember your units, in this case inches) Hope this helped :)
