Answer:
See below
Step-by-step explanation:
If the diameter is doubled, the circumference is doubled. It is shown here:
18 * 3.14 = 56.52
36 (doubled diameter) * 3.14 = 113.04
If the circumference with the doubled diameter divided by the circumference of the original diameter comes out as 2, then it is proven that doubling the diameter doubles the circumference.
113.04/56.52 = 2.
The image for the rest is attached.
Answer:
Step-by-step explanation:
The Radius is (1/2) of the diameter, so to get the diameter we will multiply the radius by 2.
1. 9*2=18in
The we multiply the diameter by [tex]\pi[/tex] to get the cicumference. We know to do this because the equation of the circumference is C=[tex]\pi[/tex]d or C=2[tex]\pi[/tex]r. (p.s [tex]\pi[/tex]=3.1415926)
2. 18in*(3.1415926)=56.5487in
3. If the diameter is doubled the circumference is also doubled. We know this because of the equation C=[tex]\pi[/tex]d. The circumference is dependant upon the diameter and grows (or shrinks) with it.

How far does an ant have to crawl to get from the base of the cone to the top of the hill? (This is the slant height, s, of the cone.) Answer the questions to find out.
Use 3.14 for π and round your answer to the nearest millimeter if necessary
1. What is the height of the cone? Explain how you found the height.
2. Now that you have the height of the cone, how can you solve for the slant heights?
3. How far does the ant crawl to get from the base of the cone to the top of the hill? Show your work.
Answers
Answer:
The slope is 29 mm.
Step-by-step explanation:
What we know:
The radius of this cone is 20 mm, and the height is 21mm
s = √r^2 + h^2
s = √20^2 + 21^2
s = √400 + 441
s = √841
s = 29 mm
Volume of cone
V = Volume of cone =
r = Radius of cone = 20 mm
h = Height
s = Slant height.

Charmaine received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.96 per pound. After buying the coffee, she had $32.24 left on her card. How many pounds of coffee did she buy?
Answers
Step-by-step explanation:
Algebraic Expression
Step 1 :- Make an equation
⇒ 7.96p + 32.24 = 80
Step 2:- Calculate for the value of variable
⇒ 7.96p + 32.24 = 80
Substract 32.24 from both sides
⇒7.96p + 32.24 - 32.24 = 80 - 32.24
Calculate
⇒7.96p = 47.76
Divide both sides by 7.96
⇒7.96p/7.96 = 47.76/7.96
Divide
⇒p = 6
Therefore, she bought 6 pounds of coffee

Mrs. Smith decides to buy 3 sweaters and a pair of jeans. She has $120 in her wallet. If the price of the jeans is $35, what is the highest possible price of a sweater, if each costs the same?
Answers
Answer:
$28
Step-by-step explanation:
First, we need to subtract 35 from 120.
120 - 35 = 85
Next, we need to divide 85 by 3 to get our answer.
85 / 3 = 28.333 (repeated)
Therefore, the answer is $28 because she cannot spend over $120 and each sweater costs the same.
Food Express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on their receipt. So far, 219 of the first 264 customers have not received a star on their receipt. So far, 147 of the 156 costumers have not received a star on their receipts. What is the experimental probability someone will win a free gallon of milk?
Answers
Answer:
3/52
Step-by-step explanation:
The experimental probability of winning a free gallon of milk will be calculated as under -
It is given that, total number of outcomes = 156
Non-winning customers = 147 (it is given in the question)
Thus, the winning customers will be = Total outcomes - Non-winning customers
Expected winning customers = 156 - 147 = 9
The probability is calculated as -
Probability (Winning customer) = winning customers/total customers
Probability (Winning customer) = = 9/156 = 3/52
Answer:
3/52
Step-by-step explanation:
The experimental probability of winning a free gallon of milk will be calculated as under -
It is given that, total number of outcomes = 156
Non-winning customers = 147 (it is given in the question)
Thus, the winning customers will be = Total outcomes - Non-winning customers
Expected winning customers = 156 - 147 = 9
The probability is calculated as -
Probability (Winning customer) = winning customers/total customers
Probability (Winning customer) = = 9/156 = 3/52

give the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet, calculate the radius (R) of the pole that will produce a perfect lawn
Answers
Answer:
The radius is 0.398 feet to produce a perfect lawn for the lawnmower.
It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.
It is required to calculate the radius (R) of the pole that will produce a perfect lawn.
What is a circle?
It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have,
Width of the lawnmower = 2.5 feet
Length of the rope = 25 feet
For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:
The perimeter of the pole = width of the lawnmower
2πR = 2.5
R = 0.398 Feet ( π = 3.14 )
Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.
The United States Postal Service delivers about 2^8 ⋅ 5^2 pieces of mail each second. There are 2^8⋅3^4⋅5^2 seconds in 6 days. How many pieces of mail does the United States Postal Service deliver in 6 days? Write your answer as an expression involving three powers.
Key: ^ means the number that comes after is an exponent. For example: 4^9, 4 is the base and 9 is the exponent.

A rabbit's fur grows at the rate of 5 over 2 inches per month.
How many months will it take the rabbit's fur to grow 15 over 4 inches?
Explain your answer using expressions and words.
Answers
Growth rate = 5/2 inches per month
The fur length after y months:
Fur length = 5/2 × y
Therefore, to have a fur length of 15/4 inches :
15/4 = 5/2 × y
3.75 = 2.5y
Divide both sides by 2.5 to isolate y
3.75/2.5 = y
1.5 = y
it will take a month and half to have a fur of 15/4 inch length
Answer:
1.5 months
Step-by-step explanation:
First, make [tex]\frac{5}{2}[/tex] so it has a common demoninator as [tex]\frac{15}{4}[/tex].
We need the demoninator to be the same so we can multiply [tex]\frac{5}{2}[/tex] by 2 to make it [tex]\frac{10}{4}[/tex].
So, a rabbit's ear grows [tex]\frac{10}{4}[/tex] of an inch in a month.
To find how many months, it will take, we have to divide [tex]\frac{15}{4}[/tex] by [tex]\frac{10}{4}[/tex].
To divide fractions, we can multiply with the reciprocal.
So, [tex]\frac{15}{4}[/tex] * [tex]\frac{4}{10}[/tex] is [tex]\frac{60}{40}[/tex] which reduces to [tex]\frac{6}{4}[/tex] which, in decimal form is equal to 1.5 months.

Pls help and explane how u got the answer PLSS
Answers
Answer:
Step-by-step explanation:
Volume of cylinder =
[tex]V=\pi r^2h[/tex]
Radius = Diameter / 2
Radius = 8 / 2
Radius = 4 cm
[tex]V = \pi (4^2)h[/tex]
Height = 16 cm
[tex]V = \pi (4^2) * 16[/tex]
[tex]V = (3.14)*(16)*16[/tex]
If [tex]\pi[/tex] = 3.14. (Most likely this one)
Than the answer is 803.8
(803.84 rounded to the nearest tenth is 803.8)
If [tex]\pi[/tex] = 3.14159

let x equal the price of the medium drink
let y equal the price of the large popcorn
let’s start by creating an equation for the couple
they bought 2 drinks and 1 popcorn for 13.85$
so, 2x+1y=13.85
let’s make an equation for the family
they bought 3 drinks and 2 popcorns for 23.90$
so, 3x+2y=23.90
let’s solve for y using the COUPLE equation
minus 2x from the right to get 1y=-2x+13.85
1y is the same as y, the the equation for the couple is y=-2x+13.85
put this y value into the y value for the FAMILY equation
3x+2(-2x+13.85)=23.90
distribute the 2 to get 3x-4x+27.70=23.90
combine 3x and -4x to get -1x+27.70=23.90
minus 27.70 from both sides to get the following:
-1x=-3.8
multiple both sides by -1 to get x=3.8
the price of one drink is 3.8$
lastly, let’s figure out the price of the popcorn.
replace the x value in the COUPLE equation with the 3.8
2(3.8)+1y=13.85
multiply 2 and 3.8 to get 7.6
7.6+1y=13.85
minus the 7.6 to get 1y=13.85-7.6
reduce the equation to get y=6.25
so, the price of one drink is 3.80$ and one popcorn is 6.25$
