A landscape architect used the entire length of an 80-foot rope to lay out a flower bed in the shape of a circle. (Drawings not to scale.)



What is the area of the circle rounded to the nearest square foot?

A Landscape Architect Used The Entire Length Of An 80-foot Rope To Lay Out A Flower Bed In The Shape

Answers

Answer 1

Answer:

Step-by-step explanation:

A square has 4 sides so 80/4= 20ft

area= 20^2

area=400 square ft

2*3.14*r = 80

r = 80/6.28

r=12.74 ft

area= A = 3.14*12.74^2

A = 509.6 sq/ft

if you wanted to find the difference:

509.6 - 400 = 109.6 sq/ft more in the circle

The inference based on the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

What is the Median of a Dot Plot?

The median is a measure of dispersion, which can give us an idea of where most of the data points lie in the data distribution that is represented in a dot plot.

The median is the middle value, having equal data points on the right and to the left.

The median for online customers is between 5 and 6.

The median for walk-in customers is 2.

Therefore, the inference to make using the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

Jose makes $8 an hour plus an
additional $240 per week in commission. How
many hours did he work last week if his
paycheck was $528?

Answers

528= 8x+240
288=8x
x=36 hours

Answer:

36 hours

Step-by-step explanation:

To find the hours Jose worked, we can write an equation with the value x as our unknown, for the hours worked.

To construct this equation, we'll list out the values we have to include. The total will equal 528, so we know 528 will be on one side of the equation.

On the other side, we have the hourly rate plus the commission, 240. The rate is 8 dollars per hour. The unknown, or hours worked, is x. So, the rate is 8x. This is added to the weekly commission to equal his weekly paycheck.

8x, the hourly rate, + 240, the commission, = 528, the total paycheck.

The equation is-

8x + 240 = 528

Now we can solve the equation.

First subtract 240 from either side of the equals sign.

8x + 240 - 240 = 528 - 240

Simplify this to get-

8x = 288

Divide 8x by 8.

[tex]\frac{8x}{8}[/tex] = [tex]\frac{288}{8}[/tex]

Simplify.

x = 36

Jose worked 36 hours last week.

I hope this helps ^^

Answers

Answer:

B 4L- 12

D 2(L -6) + 2L

Step-by-step explanation:

Perimeter is 2w + 2l, width is 6 less that length, so substitute it for w:

2w + 2l =

2(L - 6) + 2l =

2l - 12 + 2l =

2l + 2l - 12 =

Answer: Triangle: x = 40 Line: x = 10

Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°

A straight line is 180°
so 7x+110=180
7x= 70
x=10

Answer:

x = 40

x = 10

Step-by-step explanation:

Problem 1

The sum of all angle measures in any triangle is (180) degrees. In this problem, one is given that one of the angle measures is (50) another is (x) and the final is (90) degrees. A general rule is that when an angle has a box around, its degree measure is 90 degrees. One can apply this here by stating the following,

x + 50 + 90 = 180

Simplify,

x + 140 = 180

Inverse operations,

x + 140 = 180

   -140    -140

x = 40

Problem 2

The degree measure of a straight line is (180) degrees, the two given angles in this picture form a straight line. Thus, the sum of their angle measures is (180) degrees. Form an equation off of this information and solve for (x),

110 + 7x = 180

-110           -110

7x = 70

/7     /7

x = 10

Answers

Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.
