The height of the building and the distance between the house and the ladder are the legs of the triangles. He set up the formula correctly but plugged in the values in the incorrect areas

Let’s use his formula

Leg A^2 + Leg B^2 = Hyp^2

The house is one of the legs and the ladder is the hypotenuse

(15)^2 + Leg B^2 = (17)^2

Let’s isolate Leg B because we hate it and need to find it’s value.

Leg B^2 = (17)^2 - (15)^2

Let’s get rid of these exponents

Leg B^2 = 289 - 225

Subtract

Leg B^2 = 64

Leg B = 8

However, since we have 3 sets of 4, what can we do with the two exponents to avoid expansion?

Answers

Answer:

To avoid expansion, you can just use the power of a power rule and multiply the two exponents from the start.

Answer:

Its D

Step-by-step explanation:

If r is less than q, then it is on the left side because that is the lowest position avaliabe on the number line. If s is q+1, that means s is one more than q so s is bigger than q. If q is more than r and less than s, it is in the middle of those two. So, r is on the left most side, q is in the middle, and s is on the right side because it is the most.

Elsa’s friend borrows $400 with an interest rate of 1.5%. How much interest will she pay after 4 years?

Answers

Formula I = P x r x t

p is the principal amount, $400.00

r is the interest rate 1.5% a yea (0.015 in decimal)

t is time involved 4 years

so t is 4 year time periods

To find the simple interest we multiply 400 x 0.015 x 4 to get $24.00

so if you borrowed the $400 dollars you would now owe $424

Answer: so it's $24 interest or $424 since it's usually added to the principal
