PLEASE EXPLAIN HOW YOU GOT IT!!!!

Answers

Answer 1

Answer:

−r^3+r^2+r

Step-by-step explanation:

Let's simplify step-by-step.

r^2(r+1)−r(2r^2−1)

Distribute:

=(r^2)(r)+(r^2)(1)+−2r^3+r

=r^3+r^2+−2r^3+r

Combine Like Terms:

=r^3+r^2+−2r^3+r

=(r^3+−2r^3)+(r^2)+(r)

=−r^3+r^2+r

If 7 workers take 500 hours to finish a project, how long will it take 14 workers to complete the same project?

Answers

Answer:

250 hours

Step-by-step explanation: increasing the number of workers will make the project go faster. So they multiplied the 7 by 2 so now there are 14 workers so then the time it'll take to finish the project would be cut in half because now they have twice the numbers of workers. correct me if I'm wrong

What percentage of this grid is shaded?
b)
How many more squares need to be shaded
so that 80% of the grid is shaded?

Answers

Answer:

52% of the grid is shaded. You would need 7 more squares in order to get 80%.

Step-by-step explanation:

There are 25 boxes. You want to figure out how much each box is worth.

So,

You divide 100 by 25. You will get an answer of 4.

So now you know how much each box is worth.

There are 13 boxes shaded in, so you multiply 13 by 4 to get 52.

Keep adding boxes in order to get 80%. For example, 52%, 56%, 60%, until you get to 80%. Then see how many boxes you added up to get 80%.

We would need 7 more squares in order to get 80%. Thus, 52% of the grid is shaded.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

There are 25 boxes. we want to figure out how much each box is worth.

So,

100 / 25 = 4

Now, we know how much each box is worth.

There are 13 boxes shaded in,

so 13 x 4 = 52.

Keep adding boxes in order to get 80%.

For example, 52%, 56%, 60%.
