Answer:

the quarter circle's perimeter = 24.99 inch

Step-by-step explanation:

1. Calculate circumference of a complete circle.

2. Divide by 4 and you have the quarter part. (This is the same as multiplying by 0.25).

3. Just like a pie chart, there are 2 sides from the center to the left and right side edge of the quarter circle. Both are equal to the radius r.

4. Add the numbers found in step 2 and step 3 and you will have found the quarter circle's perimeter.

Given: use 3.14 for pi and r = 7 inch

1. Circumference = 2* pi * r

2. 1/4 * ( 2 * pi * r )

1/4 * ( 2 * 3.14 * 7 ) = 10.99 inch

3 Since r = 7 and we have to sides.

So you just add 2 * 7 = 14 inch

4. Add 10.99 + 14 = 24.99 inch

It would cost $20.12 because if you multiply $4.47 by 4 pounds you would get 17.88. Then, you would divide $4.47 by 2 and get 2.235 but round that number up to $2.24. After adding $17.88 and $2.24 together, you recieve a total of $20.12

Hope this helps you!

Say a certain service industry has 78.9 thousand jobs in 2003, but expects to increase at an average annual rate of 2.65 thousan
Alex_Xolod [135]

Answer:

33%

Step-by-step explanation:

In 2003, there were 78.9 thousand jobs in the industry and it increases annually by 2.65 thousand jobs from 2003 to 2013.

Hence, from 2003 to 2013, i.e. 10 years the jobs have increased by (2.65×10) = 26.5 thousand.

Therefore, the percent increase in jobs in the industry from 2003 to 2013 is given by \frac{26.5*100}{78.9} = 33.6 % ≈ 33%. (Answer)

A square has a perimeter of 12x 52 units. which expression represents the side length of the square in units? x 4 x 40 3x 13 3x
d1i1m1o1n [39]

The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

<h3>What is the perimeter of a square?</h3>

The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

P=4a

Here, (<em>a</em>) is the side of the square.

A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
