By working 8 hours per day, Marley's team can complete a task in 15.5 days. Bill's team works on the same task at the same speed; however, Bill's team works 7 hours and 45 minutes per day. How many days does it take Bill's team to complete the task?
Answers
8 Hours x 15.5 days = 124 Hours
Using this logic, we know 60 minutes in an hour and 45/60= .75. So it is 7.75 Hours.
124/7.75= 16.

2.2z + 3z = 4.5 - 3.2
5.2z = 1.3
z = 1.3/5.2 = 0.25 or 1/4
this has exactly one solution.
(4/5)x + 2/3 + (1/5)x = x
4/5 + 1/5 = 5/5 = 1/1 = 1, so
x + 2/3 = x
2/3 = 0
that is never right this has no solution at all.
2.3y + 3.2 - y = 2.1 + 1.3y + 1.1
1.3y + 3.2 = 1.3y + 3.2
3.2 = 3.2
this is always correct, no matter what numbers we use for y.
so, this has infinitely many solutions
(2/3)x + 2/3 + (1/5)x = 2/3x
2/3 + (1/5)x = 0
(1/5)x = -2/3
x = -2/3 / 1/5 = (-2×5)/(3×1) = -10/3
this has exactly one solution.
20 + 4r = 32 - 2r
20 + 6r = 32
6r = 12
r = 2
this has exactly one solution.
20+4r=32-r
20+6r=32
6r+12
R=2

why isn't m^3=512 ±8, but just 8? I went onto 2 diff websites and the answer book (yes i have an answer book) and it says 8.
Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answers
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.

Three different recipes each make a different number of cookies and require a different amount of flour.
Recipe 1: 1 dozen cookies; 1 cup of flour
Recipe 2: 3 dozen cookies; 3.5 cups of flour
Recipe 3: 5 dozen cookies; 6 cups of flour
Determine if the three recipes use a proportional amount of flour.
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent.
Yes, it is proportional because the cookies increase by 2 dozen for every 2.5 cups of flour.
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
No, it is not proportional because the number of cookies and cups of flour could not be zero at the same time.
Answers
12 cookies in a dozen.
Recipe 1 -> 12:1 -> 12:1 ratio
Recipe 2-> 36:3.5 -> 10.28:1 ratio
Recipe 3-> 60:6 -> 10:1 Ratio
I hope that helps :)
The correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
Three different recipes each make a different number of cookies and require a different amount of flour.
From the recipe:
The ratios of the number of cookies to the number of cups of flour:
For recipe 1:
= 12/1 = 12
For recipe 2:
= 36/3.5 = 10.28
For recipe 3:
= 60/6 = 10
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
Thus, the correct statement is (C) No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.

Answers
Answer: $1.54
Step-by-step explanation: 20 - 8.79 = 11.21, 11.21 - 2.69 = 8.69, and 8.69 - 6.98 = 1.54
hope this helps :)
Answer:
She has $1.54 left
Step-by-step explanation:
We know she bought a $20 giftcard,
and she spent $8.79 on Chalk Markers, $2.69 on yarn, and $6.98
on beads.
------------------------------------------
Therefore you would do
• $20 - $8.79 = $11.21
• $11.21 - $2.69 = $8.52
• $8.52 - $6.98 = $1.54
------------------------------------------
So Ellie would have $1.54 left on her gift card.
