Answer: An open circle means any number except the one in the circle. Here the number in the circle is 3. The arrows go to both sides. This means every number except 3. The answer is c. Which states that every number is included except 3. Basically meaning x is never equal to 3.

The unit rate is $8/ ticket.

Can someone help me find the constant? L varies directly as h; when l=112, h=-16

Answers

it varies directly
that means that when when L goes up, h also increases, when L decreases, h also decreases
so the constant is k where k=y/x
in this case it is k=L/h so subsitute
L=112
h=-16
k=L/h
k=112/-16
k=-7
the constant is -7

The statement is expressed as
L = kh
where k is constant
In terms of k,
k = L/h
Given L = 112 and h = 16
k = 112/-16 = -7

Janelle can get a 24-pack of bottled water for $6.80. How much would Janelle have to pay for a 12-pack of bottled water if the ratios are proportional?

Answers

She would have to pay $3.40 I think. A 12-pack is half the size of a 24-pack so I did half the price.

Answer: $3.40. I think this is the answer

Sharon earns $15 per item she sells plus a base salary of $75 per week write and solve an inequality to find out how many items she must sell to earn at least $750 per week provide your conclusion as a complete sentence

Answers

so 15 dollars per item plus 75 dollars a week is 15x + 75 where x is the number of items sold.

if she sells one item, x = 1 and she will make:

15 (1) + 75 = 90 dollars.

so that's not enough to get 750, you need more money. how? more x! how much more is enough though?

well 15x + 75 needs to = 750

so 15x + 75 = 750

move 75 over to the right and get

15x = 675

now divide both sides by 15

x = 45

so Sharon needs to sell a MINIMUM of 45 per week to earn at least 750 dollars.

saying minimum is important because the problem says at LEAST $750.

jack, jill and bill each carried a 48-ounce bucket full of water down the hill. By the time they reached the bottom, jack's bucket was only 3/4 full, jill's was 2/3 full, and bill's was 1/6 full. How much water did they spill altogether on their way down the hill?

Answers

divide 48 by 4 and you get 12 ounces. Therefore, each 1/4 of a bucket is equal to 12 ounces. divide 48 by 3 and you get 16 ounces. Therefore, each 1/3 of a bucket is 16 ounces. Divide 48 by 6 and you get 8 ounces. 8 multiplyed by 5 is 40. Add 40 16 and 12 and you get 68 ounces

68 ounces because 48/4= 12 so jack spilled 12 ounces. 48/3=16 so Jill spilled 16 ounces. 48/6=8 so bill spilled 40 ounces.12+16+40=68. Hope this helps
