A 3-yard roll of wrapping paper costs $13.14. What is the price per foot?
Answers
Answer:
Step-by-step explanation:
1 yard is equal to 3 feet.
since you have 3 yards, it'll be 9 feet.
13.14/9 to get your answer
or $1.46 per foot
The price per foot of wrapping paper is $1.46.
First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.
The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:
price per foot = $13.14 / 9 feet
= $1.46 per foot
Therefore, the price per foot of wrapping paper is $1.46.

A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send to her customers. Each of the flower pots weighs 1 lb. and 12 oz. The packing material weighs 5 oz. Will her package be labeled as "heavy"?
Answers
Answer:
No, the package will not be labeled "heavy"
Step-by-step explanation:
1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).
2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.
3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.
4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.
Final) so in the end, you would have 10lb. 13oz.

How many hours does Cesar need to practice during the rest of the week in order to have his 10 total hours?
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear. Let me help you rephrase it and solve.
Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.
The total hours that Cesar has used in practicing will be:
= 1 1/2 + 2 1/4 + 1 1/2
= 5 1/4
To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:
= 10 - 5 1/4
= 4 3/4 hours.
Cesar needs to practice for 4 3/4 hours more.
Katniss Everdeen found the absolute value of |25| to be -25.
Do you agree? Yes or No
Explain:
Answers
Answer:
No
Step-by-step explanation:
Absolute values will never be negative.
Since absolute values are simply the number's distance from zero, it can never be negative, since there are no negative distances.
In this case, | 25 | is equal to 25. This is because the distance from 0 to 25 is 25.
So, Katniss is wrong.

AWARDING DOUBLE POINTS question in pic, will report anything other than the answer
Answers
Answer:
m∠R is 72°
Step-by-step explanation:
In the given figure
∵ ΔPQR ≅ ΔUVW
→ From congruency
∵ m∠P = m∠U
∵ m∠Q = m∠V
∴ m∠R = m∠W
∵ m∠R = (10x - 18)°
∵ m∠W = 8x°
∵ m∠R = m∠W
→ Equate their measures
∴ 10x - 18 = 8x
→ Add 18 to both sides
∵ 10x - 18 + 18 = 8x + 18
∴ 10x = 8x + 18
→ Subtract 8x from both sides
∴ 10x - 8x = 8x - 8x + 18
∴ 2x = 18
→ Divide both sides by 2 to find x
∴ x = 9
→ Substitute the value of x in the m∠R
∵ m∠R = 10(9) - 18
∴ m∠R = 90 - 18
∴ m∠R = 72°
∴ m∠R is 72°

What are the x and y intercepts
Answers
Answer:
x= -27 y=18
Step-by-step explanation:
plug in zero for x to find y and plug in zero for y to find x
Answer: The x-intercept is (-27,0)
The y intercept is (0,18)
Step-by-step explanation:
For the x- intercept, Substitute 0 for y and solve for x
-2x + 3(0) = 54
-2x + 0 = 54
x = 54/-2
x = -27
For the y -intercept, Substitute 0 for x and solve for y
-2(0) + 3y = 54
0 + 3y = 54
y = 54/3
y = 18
