Answer:
Step-by-step explanation:
Using the formula for finding the circumference of a circle.
C = 2πr
r is the radius
radius = diameter/2
radius = 10/2
radius = 5in
C ,= 2(3.14)(5)
C = 20(3.14)
C = 31.4×2
C = 62.8in (for 1 rotation)
For 16 rotations;
C = 16×62.8
C = 1004.8in
The distance covered is 1004.8in
A taxi company had 12 taxis originally. After expanding the company now has 18 taxis. Is this an increase or decrease? What was the percent change?
Answer:
This is an increase by 50%.
Step-by-step explanation:
The taxi company has 12 taxis originally, and then got 6 more to get 18. They added, so that is an increase.
18 / 12 = 1.5, so it is a 50% increase.

regular pentagon
find the angles of ADC?
Answer:
Since this regular polygon has 5 vertices (implied from the ABCDE), it's a regular pentagon. (This means an equilateral, equiangular pentagon.) So, 360 deg./5 =72 deg., and 180 - 72 = 108).

Raju and Ann saved a total of $1560. After Raju gave Ann $50, Raju had 5 times as much money as Ann. How much did Raju have at first?
Step-by-step explanation:
let amt of money Raju has be r and Ann be a.
a + r = 1560
a = 1560 - r --(1)
r - 50 = 5(a + 50)
r = 5a + 300 --(2)
sub (1) into (2):
r = 5(1560 - r) + 300
r = 8100 - 5r
6r = 8100
r = 1350
therefore he has $1350 at first.

What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.
We have,
Let the amount of money Raju = R
Let the amount of money Ann = A
Now,
Raju and Ann saved a total of $1560.
This statement can be written as:
R + A = 1560 ____(1)
After Raju gave Ann $50, Raju had 5 times as much money as Ann.
This statement can be written as:
R - 50 = 5 ( A + 50 )
R - 50 = 5A + 250
R - 5A = 250 + 50
R - 5A = 300 _____(2)
From (1)
R = 1560 - A _____(3)
Putting (3) in (2),
1560 - A - 5A = 300
1560 - 6A = 300
1560 - 300 = 6A
1360 = 6A
A = 1260 / 6
A = 210
Putting A = 210 in (3) we get,
R = 1560 - A
R = 1560 - 210
R = 1350
Thus the amount of money Ann has at first is $1350.

A basketball player scored 26 points in one game. In basketball, some baskets are worth 3 points, some are worth 2 points, and free-throws are worth 1 point. He scored four more 2-point baskets than he did 3-point baskets. The number of free-throws equaled the sum of the number of 2-point and 3-point shots made. How many free-throws, 2-point shots, and 3-point shots did he make?
Answer:
3 points = 2
2 points = 6
1 point = 8
Step-by-step explanation:
Given that:
Total point scored = 26
Let number of 3 point basket = x
Number of 2 point basket = x + 4
Number of free throws = x + x + 4 = 2x + 4
Hence,
Total 3 points = 3x
Total 2 points 2(x + 4)
Total free throw points = 2x + 4
3x + 2(x + 4) + 2x + 4 = 26
3x + 2x + 8 + 2x + 4 = 26
7x + 12 = 26
7x = 26 - 12
7x = 14
x = 2
Number of 3 points = x = 2
2 points = (x+4) = 2+4 = 6
1 point = (2x+ 4) = 2(2) + 4 = 8
The number of free-throws, 2-point shots, and 3-point sho ts he made are;
free-throws = 8
2 points = 6
3 points = 2
Let the number of 3 points basket be x
He scored four more 2-point baskets than he did 3-point baskets. Thus;
y = x + 4
number of free-throws equaled the sum of the number of 2-point and 3-point sho ts made. Thus;
z = x + x + 4
z = 2x + 4
Thus;
Total 3 points = 3x
Total 2 points = 2(x + 4)
Total fr ee points = 2x + 4
Since he scored a total of 26 points, then;

You are canning 40 cups of applesauce. You have 20 glass jars, each of which will hold 134 cups of applesauce. Choose the correct explanation(s) that explain why you do not have enough jars.
You do not have enough jars because 20 jars will only hold 35 cups of applesauce.
You do not have enough jars because you have enough applesauce left to completely fill 2 more jars, and almost fill a third jar.
You do not have enough jars because you need a total of 40×134=70 jars.
You do not have enough jars because the 20 jars would need to hold 2 cups each, but each holds 14-cup less than that.

Combine like terms.
2x + 54 = 100 {Subtract 54 from both sides}

If you subtract $300 from 9.5% you get 271.5 US$

A hotel has a budget of $16,000 to buy 84 new mattresses. Each mattress costs $209. The hotel manager says, “Since 80 × $200 = $16,000, I can stay within the budget.”
Answer:
The hotel manager under-estimated. Without estimation, the exact price would be $17,556.
Step-by-step explanation:
He should've over-estimated the money to $210, and the mattresses to 90. So 210 × 90 is $18,900. So even if he did underestimate or overestimate, he still would not have been able to afford the mattresses.
