Answer:

Neither one of them is correct

Step-by-step explanation:

Since the formula to find the circumference of a circle is C = dπ or C = 2πr. We know that a diameter of the circle is the same as 2 times the radius of the circle, here Sawyer and his sister are both saying the same thing, one way or the other. When Sawyer says C = d, he should multiply the d with a pi sign to get the correct circumference. Similarly when his sister says C = 2r, she is stating the congruent equation to the one of Sawyer's, therefore she needs to multiply 2r by the pi sign to get the correct circumference. Hence, both Sawyer and his sister are wrong stating the equation to solve for the circumference of the circle.

Hope this helps!

erica [24]

Answer:

Contradictrion

Step-by-step explanation:

First write an equation. If the total is 289, then that goes one the right side of the =. Sociology textbooks will be x. If there were 65 less than x, it will be 65-x. Lets set it up:

x + 65 -x =289

Then combine like terms.

65 = 289

There are no values of x that make the equation true. The input is a contradiction.

。☆✼★ ━━━━━━━━━━━━━━  ☾  

Use the multiplier 1.055

final = original x multiplier^n

where 'n' is the number of years

Sub the values in

final = 700 x 1.055^7

final = 1018.27

Subtract the values:

1018.27 - 700 = 318.27

Thus, he earns more than $275

He earns $43.27 more

Daniel [21]

Answer:

Mean = 28.33

Step-by-step explanation:

Comment

You need two inputs. The first is the sum of the numbers and the second is the number of entries in the data.

Givens

Sum = 3 +  32 +   36 +   30 +   33 +   36

Number of entries = 6

Solution

Sum = 170

Mean = sum / number of enteries

Mean = 170 / 6

Mean = 28.33
