when chef alice makes rice pailaf for 30 people she uses 15 cups of chicken broth and 10 cups of rice dan wants to make the same recipe for 9 people write and use equations to find how much broth and how much rice dan should use
Answers
30 / 3 = 10 cups of rice
Using the same equation:
9 / 2 = 4.5 cups of chicken broth
9 / 3 = 3 cups of rice
15 cups of chicken broth + 10 cups of rice = 30 people
4.5 cups of chicken broth + 3 cups of rice = 9 people
The number of cups of chicken broth required for 9 people is 4.5.
The number of cups of rice required for 9 people is 3
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Alice makes rice pailaf for 30 people she uses 15 cups of chicken broth and 10 cups of rice.
This can be written as,
15 cups of chicken broth + 10 cups of rice = 30 people _____(1)
Now,
Multiply 9/30 on both sides.
9/30 x 15 cups of chicken broth + 10 cups of rice) = 9/30 x 30 people
9/30 x 15 cups of chicken broth + 9/30 x 10 cups of rice = 9 people
4.5 cups of chicken broth + 3 cups of rice = 9 people
Thus,
The number of cups of chicken broth required for 9 people is 4.5.
The number of cups of rice required for 9 people is 3

At a supermarket pineapple juice sells at $1 per pint (16 ounces). Greg wants to buy 18 40-ounce cans of pineapple juice from the supermarket. How much does he have to pay altogether?
Answers
Greg would need to pay a total of $45 for 18 40-ounce cans of pineapple juice, after converting the total ounces to pints at the given price of $1 per pint.
To determine how much Greg needs to pay for 18 40-ounce cans of pineapple juice, we first need to calculate the total number of ounces Greg is purchasing and then convert that to pints since the price is given per pint. One pint equals 16 ounces, so we can use this to find the cost.
Step-by-Step Calculation:
Calculate the total ounces of pineapple juice.
18 cans imes 40 ounces per can = 720 ounces total.
Convert ounces to pints since the price is per pint.
720 ounces ÷ 16 ounces per pint = 45 pints.
Calculate the total cost.
45 pints imes $1 per pint = $45 total.
Therefore, Greg has to pay a total of $45 for 18 40-ounce cans of pineapple juice.

A square has an area of 4x^{2} + 12xy + 9y^{2} square meters. What is the perimeter of the square?
Answers
Answer:
Perimeter = 4L = 4(2x+3y) = 8x+12y
Step-by-step explanation:
Given:
square with area A(x,y) = 4x^2+12xy+9y^2
Find perimeter.
A(x,y) = (2x+3y)^2
Length of each side
L = sqrt( A(x,y) ) = sqrt((2x+3y)^2) = 2x+3y
Perimeter = 4L = 4(2x+3y) = 8x+12y

Susan has raised $234 by selling 18 equally priced wreaths for the band fund-raiser. Which of the following equations can be used to find the price, y, of each wreath?
Answers
How?
18y = 234
Divide both sides by 18
(18y)/18 = 234/18
y = 234/18
y = 13
So using the equation 18y = 234, we were able to find the price of each wreath: y = $13
Hope this helps! :)

Which expression has an estimated product of 60
Answers
Specific mathematical expressions are needed to determine which has an estimated product of 60, for instance, combinations like 10 times 6 or 15 times 4.
The question relates to estimating the product of numerical expressions to determine which one is closest to 60. However, the provided information contains unrelated data and does not present clear mathematical expressions that we can evaluate to find an estimated product of 60. Thus, to accurately answer this question, we would need specific expressions to consider. In general, an expression likely to have an estimated product of 60 would be the multiplication of two numbers whose product is close to 60. For instance, numbers like 10 and 6 or 15 and 4 could be suitable factors in such expressions.

Answers
Final answer:
The ratio of dented ping-pong balls to the total number of ping-pong balls is 28/52. The ratio of Tess' height to Wendy's height is 8/9. Ben has 19 marbles.
Explanation:
Question 1:
To find the ratio of dented ping-pong balls to the total number of ping-pong balls, you need to add the number of dented balls before and after adding 12 more dented balls.
Given that there are initially 16 dented balls in a total of 40 balls, the ratio is 16/40.
After adding 12 more dented balls, the total number of dented balls becomes 16 + 12 = 28.
The total number of ping-pong balls is 40 + 12 = 52.
Therefore, the ratio of dented balls to the total number of balls is 28/52.
Question 2:
Let's assign variables for the heights of Sasha, Tess, and Wendy.
Let the height of Sasha be 3x.
Since the ratio of Sasha's height to Tess's height is 3:4, the height of Tess can be represented as 4x.
Wendy is 30cm taller than Tess, so Wendy's height is (4x + 30).
The total height of the three friends is 470cm, so we can write the equation 3x + 4x + (4x + 30) = 470.
Simplifying the equation gives us 11x + 30 = 470, and solving for x gives us x = 40.
Therefore, the ratio of Tess's height to Wendy's height is 4x/(4x + 30) = 4*40/(4*40 + 30) = 160/190 = 8/9.
Question 3:
Let's assign variables for the number of marbles Josh, Ben, and Rick have.
Let the number of marbles Josh has be x.
Since the ratio of Josh's marbles to Rick's marbles is 1:2, the number of marbles Rick has is 2x.
Ben has 15 fewer marbles than Rick, so Ben has (2x - 15) marbles.
These three quantities sum up to 70, so we can write the equation x + 2x + (2x - 15) = 70.
Simplifying the equation gives us 5x - 15 = 70, and solving for x gives us x = 17.
Therefore, Ben has 2x - 15 = 2*17 - 15 = 19 marbles.
He first term of a sequence is 2, and each subsequent term is the reciprocal of the square of the preceding term. what is the positive square root of the fifth term?
Answers
We know that the first term is 2, this means that the second term is:
1/(2)^2 which is 1/2
The third term in the sequence would be:
1/(1/4)^2 = 1/(1/16) = 16
The forth term in the sequence would be:
1/(16)^2 = 1/256
The fifth term in the sequence would be:
1/(1/256)^2 = 1/(1/65536) = 65536
Now, the question asks for the positive root of the 5th term, this means the positive root of 65536 which is 256
