Answer:

True

Step-by-step explanation:

Correct.

For example.

Suppose the actual yield is of 80 and the theoretical yield is of 100. We want to, for example, know the percentage of the yield. First we divide 80 by 100, which is 0.8, a decimal value. To write as a percentage, we multiply it by 100.

So the correct answer is:

True

Sylvia is hiking from Mineral Creek to Blueberry Hilla distance points of 6 1/5 miles. After hiking 2 2/3 miles , Sylvia stops f

Margarita [4]

Given:

Total distance = $6\dfrac{1}{5}$ miles

Hiking before lunch = $2\dfrac{2}{3}$ miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance

$6\dfrac{1}{5}=2\dfrac{2}{3}+x$

$\dfrac{(6\times 5)+1}{5}=\dfrac{(2\times 3)+2}{3}+x$

$\dfrac{30+1}{5}=\dfrac{6+2}{3}+x$

$\dfrac{31}{5}=\dfrac{8}{3}+x$

Isolate variable term.

$\dfrac{31}{5}-\dfrac{8}{3}=x$

$\dfrac{93-40}{15}=x$

$\dfrac{53}{15}=x$

It can be written as

$\dfrac{45+8}{15}=x$

$\dfrac{(3\times 15)+8}{15}=x$

$3\dfrac{8}{15}=x$

So, $3\dfrac{8}{15}$ miles left to hike.

Therefore, the correct option is C.

Using equivalent ratios to find a whole \/

Shkiper50 [21]

Answer:

Step-by-step explanation:

So there are 20 kids with brown hair and this represents 80% of the class total.

So this means 20=.8n since we don't know the total number of kids.

20=.8n

Divide both sides by .8

25=n

So 25 is the total number of kids.

C. is the answer

You could also setup this equation given that 80% is 80/100:

[tex]\frac{20}{\text{ total }}=\frac{80}{100}

To figure out what that total is there you can divide top and bottom of the fraction on right hand side by 4 which gives you the 20 on top and the 25 on bottom.
