12 kids brought gifts to the party. This was 60% of the kids who attended the party. What equation can be used to find the number of kids who attended the party?
Answers
Answer:
Number of kids who attended the party = 12 / 0.60
Step-by-step explanation:
60% = 12
\(x\) x 0.60 = 12
Number of kids attending = \(x\) = 12 / 0.60

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

4. Chris and Keith went to a carnival. Chris started with 80 tickets and spent x tickets at the carnival, Keith started with 140 tickets and spent 2x tickets at the carnival. At the end of the night, they had the same number of tickets left over. How many tickets did Chris spend at the carnival?
Answers
Answer: x=20
Step-by-step explanation:
3x+80=140
3x=60
x=20
Answer: Chris spent 60 tickets at the carnival.
Step-by-step explanation:
At the end of the night, both Chris and Keith had the same amount of tickets, so:
80 - x = 140 - 2x
Now, solve the equation. Start by bringing the -2x to the left side.
80 - x + 2x = 140
Bring the 80 to the right side so the variables are isolated.
-x + 2x = 60
Add like terms.
x = 60
Check the work.
Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20
Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20
So, Chris spent 60 tickets at the carnival.

Find the volume of a pyramid with a square base, where the perimeter of the base is
16.9 cm and the height of the pyramid is 19.6. Round Your answer to the nearest tenth of the cubic centimeter.
Answers
Answer:
116.6
Step-by-step explanation:
Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.
Perimeter (4×Length) = 16.9 cm
Length = 16.9÷4 = 4.225 cm
Area = L² = 4.225² =
Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

Answer: The area of the given shape is 9.734 meter square
Step-by-step explanation:
The given shape is a square with 4 sides of equal dimensions "a",
Area of Square = Square of its side "a"
Here, a = Hypotenuse of the inner triangle
Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.
Step 2: By using Pythagoras theorem,
Square of the base + Square of the height = square of the Hypotenuse
(2.4)^2 + (2.0)^2 = 9.76
Therefore the value of the hypotenuse = 3.12m
The area of the square = 9.734 meter square.

So far this year, Adam has played 30 games of chess and has only won 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
A) 24
B) 57
C) 87
D) It is not possible for Adam to do this.
The correct answer is B) 57, but not sure how?
Answers
Answer:
Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.
So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:
image
You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.
Let’s do some math!
image
So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.
Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.
His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.

John’s car can travel 40 miles on 4 gallons of gas? This cost a total of $30 for the gas. How many gallons of gas would it need to travel 100 miles?
Answers
Answer: 10 gallons
Step-by-step explanation: 40 divided by 4 is 10, apply same knowledge
Answer:
10 gallons of gas
Step-by-step explanation:
If John's car can travel 40 miles on 4 gallons of gas, then it can travel 10 miles on 1 gallon of gas.
To travel 100 miles, the car would need 100/10 = 10 gallons of gas.
Since it cost $30 for 4 gallons of gas, 1 gallon of gas would cost $30/4 = $7.50.
Therefore, it would cost 10 x $7.50 = $75 for the car to travel 100 miles.
