Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of the fish pond, rounded to the nearest foot? Use 3.14 to approximate pi.

Answers

Answer 1
Answer: it would be 9 ft. using the knowledge of \pi times the diameter (\pi equals aprox. 3.14) equal the circumference of a circle, and since we know the circumference, we need to divide that by \pi to get the diameter.

equation:  28/3.14=8.913 
                 rounding that would bring it to 9 ft.

Determine which of these does NOT illustrate two quantities that combine to make 0. A) Jane collects 12 seashells and then loses 12. Eliminate B) Sharon lost 8 pounds and then gained 10 pounds. C) A business's profit if its income is equal to its expenses. D) Frank wins five dollars and pays back a $5 debt to a friend.

Answers

Answer:

Option B is the correct answer.

Step-by-step explanation:

A. Jane collects 12 seashells and then loses 12.  This combines to become 0. as first Jane gets 12 shells and then loses same 12 totaling to 0.

B. Sharon lost 8 pounds and then gained 10 pounds. This does not combine to become 0. As Sharon lost 8 pounds then gained 10 making it a total of 10-8=2 pounds.

C. A business's profit if its income is equal to its expenses. When the income and expense are equal, the profit is 0. Like you earned $100 and you spent $100, so you have basically 0.

D. Frank wins five dollars and pays back a $5 debt to a friend. This also combines to get 0. Frank gets $5 and then loses it by paying debt, so he is left with 0.

Therefore, option B is the only correct answer.

13-9x7divided by(4+3)=

Answers

answer is 4

because 13 - 9 is 4
then 4 x 7 is 28
then 4 + 3 is 7
so 28 / 7 is 4












so (13-9)*7  so 13-9 is 4.

so 4*7= 28

and then you have to do 4+3 = 7

so 28/7 will be 4 you the answer is 4.

What is 3 ft. Times 6 1/2 in. Times 6 1/2 in.?

What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?

Answers

Answer: 6,8 and 10

Step-by-step explanation:

To find the length , all we need to find is the distance between each point ,

the formula for calculating distance between two points is given by :

D = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

Let the points be :

A ( -5,-1)

B(-5,5)

C(3,-1)

Calculating the length AB , we have

D1 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D1 = \sqrt{(-5+5)^(2)+(5+1)^(2)}

D1 = √(36)

D1= 6

Calculating the length AC , we have

D2 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D2 = \sqrt{(3+5)^(2)+(-1+1)^(2)}

D2 = √(64)

D2 = 8

Calculating the length BC , we have

D3 = \sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}

D3 = \sqrt{(3+5)^(2)+(-1-5)^(2)}

D3 = √(100)

D3 = 10

Therefore ,the length of the sides of the triangle are 6,8 and 10
