Lengths are 11cm , 13cm , 16cm , 12cm

Step-by-step explanation:

Perimeter = Sum of measure of all the sides of quadrilateral.

In the question , perimeter = 52 cm

So,

[tex]x + (x + 2) + 2(x - 3) + (x + 1) = 52[/tex]

[tex] = > x + x + 2 + 2x - 6 + x + 1 = 52[/tex]

[tex] = > 5x - 3 = 52[/tex]

[tex] = > 5x = 52 + 3 = 55[/tex]

[tex] = > x = \frac{55}{5} = 11[/tex]

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.

Answer:

[tex]4[/tex]

Step-by-step explanation:

if 30days =6workers

20days =?

[tex] = \frac{20 \times 6}{30} \\ = 4[/tex]

Proportions can be inverse, direct, joint or combined.

They need 9 workers to complete the job in 20 days

Represent time with t, and the workers with w.

So, the proportional relationship is:

[tex]t\ \alpha\ \frac 1w[/tex]

Express as an equation

[tex]t\ =\ \frac kw[/tex]

Where k represents the proportionality constant

Make k the subject

[tex]k =wt[/tex]

6 workers complete the job in 30 days.

This means that: w =6, and t =30

So, we have:

[tex]k =6 \times 30[/tex]

[tex]k =180[/tex]

Substitute 180 for k in [tex]k =wt[/tex]

[tex]180 = wt[/tex]

In 20 days. we have:

[tex]180 = w \times 20[/tex]

Divide both sides by 20

[tex]9 = w[/tex]

Rewrite as:

[tex]w = 9[/tex]

Hence, they need 9 workers to complete the job in 20 days

Answer:

1.08 is the constant of proportionality.

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

The constant of proportionality is 20 because: Pay = 20 × Hours worked

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.
