I hope this is what it's asking
Step-by-step explanation:
the advantage would be that basically you don't have to do any real number calculations, you just take all of the steps and put it into one, so if u had real numbers you could just plug them in with the equation

An anthill has a volume of 8792 mm3 of dirt. Its radius is 20 mm.
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.

write the expression for when you translate the graph of y=|x+7| on unit to the left
Answers
Answer: y = |x+8|
Step-by-step explanation:
To shift the graph to either the left or right, you must change the expression inside the absolute value sign. To move the graph to the left, you must add to the inside of the absolute value sign, and to move to the right subtract from the inside of the sign. In this case, you will add 1 to |x+7| to shift to the left, so the answer should be y = |x+8|.
Answer:
y = |x+8|

Answer:
6: We already know the diamer, which is 18, and the radius which is half of 18. So 18 gets multiplied by PI (In this case 3.14) 3.14*18=56.52, or 56.5. Then we divide it by 2 (Cause it's a half circle.) which is 28.25.
7: 20*3.14=62.8/2=31.4
8: 8*3.14=25.12/2=12.56
(Because this time we didn't know the diameter, but 4+4=8.)

If you just compare the x part of the coordinate, to the y part of the coordinate, the answers obvious. for example, the first labeled point is (1 and 2/3, 1 and 1/3) the y part is 1/3 less than the x part. so y is 1/3 less than x
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.

Key: ^ means the number that comes after is an exponent. For example: 4^9, 4 is the base and 9 is the exponent.
Answers
Answer:
The total number of pieces delivered in 6 days is the number delivered each second (28.52) times the number of seconds in 6 days (28 34.52). This gives:

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

Probability (Winning customer) = winning customers/total customers
Probability (Winning customer) = = 9/156 = 3/52

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
