Answer:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.
Step-by-step explanation:
Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:
d = 2r
From:
d = 2r
Divide both side by 2
r = d/2
The radius is half the diameter.
Circumference (C) of a circle is given by:
C = 2πr
C = π2r
Recall:
d = 2r
C = πd
C = πd
Divide both side by d
π = C/d
C = πd
Divide both side by π
d = C/π
C = πd
π = 3.14
C = 3.14 × d
Thus, the circumference is 3.14 times the diameter.
SUMMARY:
The correct statement from the above illustration is given below:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.

"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Answer:
twelve decreased by twice a number > 12 - 2x
8 times the sum of number and 4 > 8 (x + 4)
12 - 2x = 8 (x + 4) then 12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Justin and his friend Dan went to the movies. If they each bought popcorn for $4.25 and a soda for $2.25, what was their total bill after adding 5 ¼ % sales tax?
Answers
Answer:$6.84
Step-by-step explanation:
$4.25 + $2.25 = $6.50
5 1/4% in decimal form is 5.25%
6.50 multiplied by 5.25% = $0.34
$6.50 + $0.34 = $6.84

Answer:
the ans is 5
Step-by-step explanation:
2j+5=3+2j+2 cancel equal terms which is 2j
so what we have left is
5=3+2
5=5
so 5 is the ans
Answer: infinity many solutions
Step-by-step explanation:
2j + 5 = 3 + 2j + 2
Combine numbers in the right side
2j + 5 = 2j + 5
Minus the smallest j from both side in this case u get rid of both j’s which mean -2j
5 = 5
Divide by 1 or -5
Which mean we get 5 = 5 or 0 = 0

1. A group of students went to the movie theater.
Eighteen of the students bought popcorn.
The other 60% of the students bought candy.
How many students were in the group?
2.There are 21,000 fans at a football game cheering for the home team. The other 40% of the total people in attendance are cheering for the away team. How many people are in attendance at the game?
3.Ashley sees a book bag on sale in a store for $22. This is 20% off the original price. What was the original price of the book bag?
Answers
So the other 40% of students is 10 students. In total there are 28 students
2. 21,000 - 40% = 12,600
There are 33,600 people in attendance.
3. $26.40 is the original price
NUMBER 1
If 18 people is 40% that means the we need to start taking 40% off of numbers
40% of 20 is 12
40% of 25 is 15
40% of 30 is 18
So the answer is 30
NUMBER 2
If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game
NUMBER 3
You should start taking 20% off of numbers.
20% of 25 is 20 too low so we need to go higher
20% of 26 is 20.8 still too low so lets keep going
20% of 27 is 21.60 closer but too low
20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between
20% of 27.5 is 22.00
So the answer is $27.5.

Answer:
The answer is 96 yd 2
Step-by-step explanation:
First for the triangle bases, you multiply the 3 by 4 and divide by 2 to get one base which is 6, then double it to get the other base on the top to get a total of 12. Then you just find the area of the other sides of the prism by multiplying the lengths and widths.

4x7=28
3x7=21
then you add all of the total values together:

A computer store buys a computer system at a cost of 463.20$. The selling price was first at $772, but then the store advertised 40% a markdown on the system.Find the current sale price.
Answers
$243.6
Step-by-step explanation:
Markdown= Selling price × markdown rate
= 812×30%
=812×0.3
=243.6
The current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
What is the selling price?The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.
Given:
The cost price = $463.20,
The initial selling price = $772,
We know that Markdown= Selling price × markdown rate
Markdown = 772 × 40%
Markdown = 772 × 0.4
Markdown = $308.8
So new selling price = The initial selling price - markdown price
Current selling price = 772 - 308.8
Current selling price = $463.2
Therefore, the current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
