Answer:

169 sq. units

Step-by-step explanation:

If the perimeter of a square is 52, then one of its side lengths will be 13. This is because the side lengths of a square are all equal: you can find the length of one side by just dividing the perimeter by 4. Now that you have the length of one side, you can find the area of a square by multiplying said length by itself. 13 x 13 = 169.

a carpenter lays 16 squares feet of tiles in 1.5 of an hour.how many squares feet of tiles does the carpenter lay per hour?

lesya [120]

I believe that the answer is about 11 square feet because when you divide 16 by 1.5, you get 10.666666667, and most likely they won't be accepting an answer like that. So, you round to the nearest square feet and you get 11.

In the figure to the right, if AC=19 and BC=16, what is the radius? *For a circle*

ch4aika [34]

Answer:

The radius of the circle is 10.2 units

Step-by-step explanation:

The complete question is

In the figure to the right, if AC=19 and BC=16, what is the radius?

A circle has center A. Points B and D are on the circle, with B on the left and D near the bottom. Point C lies outside the circle such that the line segment A C passes through point D and the line segments A B and B C form a right angle.

The radius is approximately (Round to the nearest tenth as needed.)

The picture of the question in the attached figure

we know that

In the right triangle ABC

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$19^2=AB^2+16^2$

solve for AB

$AB^2=19^2-16^2$

$AB^2=105\\AB=10.2\ units$

Remember that the radius is the same that the segment AB

therefore

The radius of the circle is 10.2 units

If the point (x,-1) is on the unit circle what is the value of x

finlep [7]

A unit circle has its center at the origin and has a radius of one. It is modeled by the equation
x² + y² = 1

We are given with (x,-1) .
Solving for x
x² + (-1)² = 1
x = 0

REBECA HAD 9/10 OF A YARDOF RIBBON. THEN SHE GAVE 7/20 OF A YARD OF FRIEND. HOW MUCH DOES SHE HAVE LEFT?

zzz [600]

Answer:

She has 11/20 yds left

Step-by-step explanation:

We take what she had and subtract what she gave away

9/10 - 7/20

We need to get a common denominator of 20

9/10 *2/2 - 7/20

18/20 - 7/20

11/20

She has 11/20 yds left
