What is the value of x? 12 units 15 units 20 units 25 units

Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

$(1).9^2+x^2=SR^2$

$(2).16^2+x^2=RQ^2$ and

$(3).SR^2+RQ^2=(9+16)^2$

Now from equations (1) and (2) we have values for $SR^2$ and $RQ^2,$ so we put those into the equation (3) and get:

$9^2+x^2+16^2+x^2=(9+16)^2$

$\rightarrow 337+2x^2=625$

$\boxed{\therefore x= 12.}$

Therefore the answer is 12 units.

you have a large container of olive oil. You have used 22 1/2 quarts of oil. Twenty- five percent of the oil remain. How many qu

Alex Ar [27]

Answer:

7.5 quarts of olive oil remain.

Explanation:

Let

q = quarts of olive oil remain

25% of olive oil remains means that 75% has been used.

2212 quarts = 22.5 quarts used

22.5.75=q.25

Multiply both sides by .25 to isolate q.

22.5.75(.25)=q.25(.25)

5.625.75=q

7.5=q
