Yes. For example, 25. The square root of 25 is 5 because 5*5=25. Multiplying two negatives always= a positive, so -5*-5=25.

Answer:

A.

We can see that the rectangles are congruent meaning they can be mapped onto one another perfectly and therefore 13 and t make up a rectangle the same size and shape as the second one. This means that 13+t will add to 17 since the rectangle they make up is congruent to the second one

out of 125 children at summer camp 45 signed up for swimming 38 for arts and crafts if a child is randomly selected what is the
anzhelika [568]
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696

Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

Corey spent 25% of his savings on a printer at Louie’s Electronics.
KengaRu [80]
Let c represent the original amount that this guy had saved up.

He spent 25% of this amount, or 0.25c, on the printer. 

To progress further, we have to know how much the printer cost.

Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.

Thus, his savings originally amounted to c = $100/0.25 = $400.
