The value of a ratio

Answers

Answer:

Students understand the value of a ratio A: B is A/B. ... If two ratios are equivalent, they have the same value. Grade 6, Module 1, Lesson 8: Classwork. Recall that when given a ratio A: B, where B ≠ 0, we call the quotient, A/B, the value of the ratio.

Step-by-step explanation:

For example, the most common way to write a ratio is as a fraction, 3/6. We could also write it using the word "to," as "3 to 6." Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.


Which of the ratios below is equivalent
to 5:2? Select all that apply.
A) 6:3
B) 10:25
C) 20:8
D) 10:4
E) 30:12

Answers

Answer: C, D, and E

Step-by-step explanation:

5/2 * 4/4 = 20/8

5/2 * 2/2 = 10/4

5/2 * 6/6 = 30/12

Answer:

C,D,E

Kristina, Liz, and Heather all made cookies. Kristina made 1.8 dozen less than 6 times as many dozen as Heather. Liz made 2.7 dozen more than 5 times as many dozen as Heather. If Kristina and Liz made the same number of cookies, how many dozen cookies did Heather make?

Answers

Answer:

Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.

Step-by-step explanation:

In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made.  Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation  6c - 2.4.  Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8.  We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8.  Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2

The ratio of black marbles to red marbles is 3:2. If there are a total of 25 marbles in a bag,
how
many
black marbles are in the bag?

Answers

Answer:

15 black marbles

Step-by-step explanation:

So its. A ratio (basically a fraction)

3/2

we add them up so we know how much marbles but not which kind

so we get 5

now we know for every 5 batches there is 3 black and 2 red

so we divide 25/5 to get 5

now we know there are 5, 5 batches of black ad red marbles.

now black is 3 of them so we multiply 5(3) which is 15

Now red is 2 of them so we multiply 5(2). Which is 10

now to check, if we add them up, they equal to 25 which is correct.

basically add the fraction, divide that by the original number, time the quotient by each number in the fraction.

Answer:

There are a total of 15 black marbles in the bag.

Step-by-step explanation:

Well, we know that for every 3 black marbles, there are 2 red marbles. In order to solve this problem, we just need to keep adding equivalent ratios with a proportional relationship until the sum of both numbers is 25.

3:2, 6:4, 9:6, 12:8, 15:10

Since 15 + 10 = 25, we can stop here.

Since the number in front of the colon is the amount of black marbles, then there are a total of 15 black marbles in the bag.

Hope this helps! :D

You’d do exponents first according to pemdas so 3^6 which equals 729 (you can get that by multiplying 3 by itself 6 times( 3x3x3x3x3x3)) then the next part is x3 so 729x 3 =2187

. Jaime's hourly wage is $16 and her net pay is 65% of her earnings. Jaime spends about $1,300 on her monthly
expenses. If Jaime works 40 hours per week and has no other sources of income, what is her total monthly cash
inflow? (Hint: Assume that there are 4 pay periods per month.)

Answers

Answer:

Monthly income is $1664, positive balance each month is $364

Step-by-step explanation:

Hourly wage = $16Net pay = 65%Monthly spending = $1300Work hours = 40 hours per week = 4*40 = 160 hours per month

Monthly earning:

160*16 = 2560

Monthly net payment:

$2560*0.65 = $1664

Remaining balance per month after expenses:

$1664 - $1300 = $364

Step-by-step explanation:

The constant value (often written k) relating amounts that rise or fall uniformly together.

It is the ratio of the amounts y and x:

k = y/x

Put another way: y = kx

Example: you are paid $20 an hour
