Answers
Answer:
1 4/5 pounds
Step-by-step explanation:
15-6= 9
9-4=5
3/5+4/5=7/5 or 1 2/5
5-1=4
4-2/5=3 3/5
half of 3 is 1.5 or 1 5/10
3/5=6/10 half of 6/10 is 3/10

1. Lily wants to buy 4 pounds of cereal for her camping trip. The boxes are each 18 ounces. According to the number line, how many boxes will she need to buy to have at least 4 pounds? 18 36 72 +++ 26 32 48 80
1: 2 boxes
2: 5 boxes
3: 3 boxes
4: 4 boxes
Answers
Answer: 4 boxes.
Step-by-step explanation:
We know that each box has 18 ounces of cereal.
We know that:
1 lb = 16 oz
Then:
1 = (1lb/16oz)
Then we can write:
18 oz = 18oz*(1lb/16oz) = (18/16) lb
This means that each box has (18/16) pounds of cereal.
Now, how many boxes we need to buy if we want to have at least 4 pounds of cereal?
If we buy N boxes, we will have N*(18/16) lb boxes of cereal.
Let's find N such that:
N*(18/16) lb = 4lb
N = 4*(16/18) = 3.56
But you can not have a 0.56 of a box, so we should round our number up to the next whole number, then we get:
N = 4.
She should buy 4 boxes.

It has been estimated that a certain stream can support 85,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1700 fewer fish can be supported. Assuming the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x.
Answers
Answer:
[tex]p = 85000 - 1700x[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Fish = 85000[/tex]
[tex]Rate = 1700[/tex]
Required
Determine the equation
For 1 ton, there is a reduction of 1700 fishes
This implies that:
For x tons, there will be a reduction of 1700x fishes
So, the function is:
[tex]p = Initial\ Fishes - Rate * x[/tex]
We used minus because the number of fishes reduced.
So, we have:
[tex]p = 85000 - 1700*x[/tex]
[tex]p = 85000 - 1700x[/tex]
Hence, the function is: [tex]p = 85000 - 1700x[/tex]

35.84
Step-by-step explanation:
32x1.12=35.84
Answer:
$35.84
Step-by-step explanation:
Hi! Ace here.
The easiest way to do this is to use benchmark fractions.
10% of 32 = 3.2
1% of 32 = .32
1% of 32 = .32
Add up all the numbers:
3.2 + .32 + .32 = 3.2 + 64 = 3.84
Since it's a mark up, we do:
32 + 3.84 = $35.84
You can also use percent proportions which would look like this. I'm not going to explain it that much because I think that's what the other person did.
[tex]\frac{x}{112} =\frac{32}{100}[/tex]
[tex]x=\frac{112*32}{100} \\\\x=\frac{3584}{100} \\\\x=35.84[/tex]
