1. (02.01 MC) Celine has a bottle that contains 20% milk and the rest water. The bottle has 1 liter of water. Part A: Write an equation using one variable that can be used to find the total number of liters of milk and water in the bottle. Define the variable used in the equation. (5 points) Part B: How many liters of milk are present in the bottle? Show your work. (5 points) (10 points)
Answer:
A. Total number of liters = 1.25 liters
B. Milk = 0.25 liters
Step-by-step explanation:
Let
x = total number of liters ( milk + water )
Milk = 20% of x
= 0.2x
Water = 1 liter
Total number of liters = milk + water
x = 0.2x + 1
x - 0.2x = 1
0.8x = 1
Divide both sides by 0.8
x = 1 / 0.8
= 1.25
x = 1.25 liters
Total number of liters = 1.25 liters
B.
Liters of milk in the bottle = Total number of liters - liters of water
= 1.25 liters - 1 liter
= 0.25 liter
Milk = 0.25 liters

Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made another 8 ft of sausage links and used 12 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night?
Answer:
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
Step-by-step explanation:
Amount of sausage links made on Friday morning = 8 ft
Amount of sausage links used on Friday night = 4 ft
Amount of sausage links remaining = 8 - 4 = 4ft (i)
Amount of sausage links made on Saturday morning = 8 ft (ii)
So,
Total amount of sausage links = 8 + 4 = 12 ft (from (i) and (ii) )
Amount of sausage links used on Saturday night = 12 ft
Amount of sausage links remaining = 12 - 12 = 0 ft
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
2. The hamster, x, walked 20 feet. The guinea pig walked 1/4 less than that. The guinea
pig walked
feet
You question is a little unclear but I'm going to assume you meant how much the guinea pig walked.
The hamster walked 20 feet, and the guinea pig walked 1/4 less. So you find 1/4 of 20, which is 5. Then, you subtract 20 and 5: 20-5 = 15. So the guinea pig walked 15 feet.

Which equation can be used to find T the number of tickets each class needs to sell so that the total amount raised is the same for both classes
Answer:
C.
Step-by-step explanation:
If you know how much each class is selling tickets for and how much they've already raised then you take those two values and set them equal to each other.
2.5t + 350 = 3t + 225
To actually find the number of tickets each class would have to sell you would just solve for t.

the square root is 7.2111111. thats the closest
Answer:
C. l
Step-by-step explanation:
The square root of 52 is about 7.211.
Since there is a negative sign in front of the square root, then it means that the answer is about -7.211.
On the number line you have a little bit over -7.3, a little less than -7.3 and a little more than -7.2. The closest answer would be the point that is a little more than -7.2.
Please correct me if I am wrong. I hope this helps!

The supplementary angle of 57° is
Answer:
123°
Step-by-step explanation:
A supplementary is an angle where two angles add up to be 180°.We can subtract to find its supplement.
180 - 57 = 123°
Best of Luck!
Answer:
123°
Step-by-step explanation:
The supplementary angle is the other angle that makes both angles a linear pair.
So you would do 180° - 57° to solve your answer, which equals 123°

Tom bought 2 pounds bananas for $3. How much would it cost for 5 pounds of bananas?
Answer:
It would be $7.50.
Step-by-step explanation: 2 pounds of bananas is $3, so we know that 4 pounds of bananas would be $6. Now, 1 pound of bananas would be $1.50! Because 1 pound is half of 2 pounds. Knowing this, one pound of bananas would be $1.50, beucuase its half.

The question: Jill jumped 6 1/3 feet in the long jump. Jill’s best friend jump 6 5/7 feet. How much farther did Jill’s best friend jump?
Now I know the answer is 8/21 but every-time I look up the decimal it’s like 0.3823. But, the next question that talked about if she jumped more than 6.5 feet then the seventh graders get fifty points. Now, I have tried to look up the answer cause I though I was missing something and it all has said the best friend jumped more than 6.5. How? If the decimal was like 0.3823.

Sorry i cant add a explanation, because im still learning about it.If u place a 13 foot ladder against a 12 foot building,how many feet will the Ladder be from the building
Answer:
5 feet
Step-by-step explanation:
When you place the 13 foot ladder, the ladder, floor, and wall forms a right triangle and the ladder will become the hypotenuse.
We use the Pythagorean Theorem. Let x be the distance from the building.
x^2 +12^2 = 13^2
x^2 + 144 = 169
x^2 = 169 - 144
x^2 = 25
Take the square root of 25 and you get 5
x = 5
