Answer:

Step-by-step explanation:

There are two ways you could do this. You could multiply the two numbers together and take the cube root of the result

$\sqrt[3]{216}$

Use y^x key or ^ key to find the answer.

216^0.33333333 = 6

or you could take the cube roots separately

$\sqrt[3]{8} = 2\\\sqrt[3]{27}=3$

And multiply those two results together

2 * 3 = 6

Your choice. The answer is going to be 6 either way.

8 = 2^3
27 = 3^3
(2^3)*(3^3)=6^3
Cube root of 6^3 = 6

Mortar is made by mixing cement, sand and quicklime in the ration 1:2:3

timurjin [86]

Answer with step-by-step explanation:

If the ratio for the ingredients is 1:2:3, then the total would be 6. If so, we have to divide 2.1 by 6, which is 0.35. Now, you need to multiply 0.35 to the according ingredient amounts.

Cement: 1 x 0.35 = 0.35

Sand: 2 x 0.35 = 0.70

Quicklime: 3 x 0.35 = 1.05

If you add it up, you will get 2.1, which is the volume.

Hope this helped! (brainliest please)

Gina's literacy bucket weighs 6 pounds. Her novel weighs 1 4/6 pounds, and her chrome book weighs 2 1/6 how much would her bucke

Paraphin [41]

Answer:

$2\frac{1}{6}$ pounds.

Step-by-step explanation:

We have been given that Gina's literacy bucket weighs 6 pounds. Her novel weighs 1 4/6 pounds, and her chrome book weighs 2 1/6.

To find weight of bucket after taking out the two items, we will subtract weight of each item from 6 pounds as:

$\text{Weight of bucket}=6-1\frac{4}{6}-2\frac{1}{6}$

Let us convert mixed fractions into improper fractions as:

$1\frac{4}{6}=\frac{6\cdot 1+4}{6}=\frac{10}{6}\\\\2\frac{1}{6}=\frac{6\cdot 2+1}{6}=\frac{12+1}{6}=\frac{13}{6}$

$\text{Weight of bucket}=6-\frac{10}{6}-\frac{13}{6}$

$\text{Weight of bucket}=\frac{6\cdot 6}{6}-\frac{10}{6}-\frac{13}{6}$

$\text{Weight of bucket}=\frac{36}{6}-\frac{10}{6}-\frac{13}{6}$

Combine numerators:

$\text{Weight of bucket}=\frac{36-10-13}{6}$

$\text{Weight of bucket}=\frac{13}{6}$

$\text{Weight of bucket}=2\frac{1}{6}$

Therefore, the weight of the bucket is $2\frac{1}{6}$ pounds.
