I think you've written s along with p^2 by mistake. if so, your answer is 2p^2+8pq-q^2.

.. 600 is what percent of 150?
Roman55 [17]

Answer:

400%

Step-by-step explanation:

We can write a percent proportion:

600/x = 150/100

a:b = c:d

a and d are linked and b and c are linked. So if a is missing, you would do (b*c)/d to get a, if b was missing, you would do (a*d)/c to get b, etc.

So over here we do

(600*100)/150 = 60,000/150 = 400, so x = 400, so that means it's 400% of 150

We can also use benchmark fractions which I find much easier:

100% of 150 is 150.

So 200% of 150 is 300

So 300% of 150 is 450

And 400% of 140 is 600

Every time it increases by 100%, it also increases by 150 on the other side, which makes sense

Let me know if you have any questions.

Consider the diagram showing the path Joel biked.
Tems11 [23]

Answer:

He would 36 miles all together.

Step-by-step explanation:

Consider the diagram showing the path Joel biked. Joel biked 9 miles east and then 12 miles north. If he biked back to his starting point using the most direct route, he would have ride 36 miles all together. Joel’s starting point is x.

In order to solve this, we must use the Pythagorean theorem.

The amount of miles would be found by adding the 3 sides together to find the sum or answer.

15 + 9 + 12 = 36 miles
