The ratio 20/10=5/n. What does n equal?

1 answer:

6 0

N is equal to 2.5

I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5

Or we can do this solution.

20 5
---- = ---- ; do cross multiplication. 20n = 10(5)
10 n

20n = 50 ; to get n, divide both sides by 20. 20n / 20 = 50 / 20 = n = 2.50

Whichever way: 20/10 = 5/2.5

I have the first part down, but I don't understand how to solve. It's an inequality.

Anna71 [15]

Answer:

As shown in your game, you have an inequality:

2.5 x h + 10.9 > 33.4

=> 2.5 x h > 33.4 - 10.9

=> 2.5 x h > 22.5

=> h > 22.5/2.5

=> h > 9

Hope this helps!

A mug is 1/8 full. The mug contains 1/6 of a cup of water. Find the capacity of the mug. Write the answer as a fration or mixed

Answer:

The capacity of the mug = $1\frac{1}{3}$ cups

Step-by-step explanation:

Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.

To find - Find the capacity of the mug. Write the answer as a fraction or mixed number

Proof -

Let the capacity of water = x

Given that,

A mug is $\frac{1}{8}$ full of water

⇒Total cups of water in the mug = $\frac{1}{8} x$

Now,

Given that, The mug contains $\frac{1}{6}$ of a cup of water.

∴ we get

$\frac{1}{8} x$ = $\frac{1}{6}$

⇒x = $\frac{1}{6}$ × 8

= $\frac{8}{6}$

= $\frac{4}{3}$ = $1\frac{1}{3}$

⇒x = $1\frac{1}{3}$

∴ we get

The capacity of the mug = $1\frac{1}{3}$ cups
