Lelu [443]

Answer: -600 and 1600 were invested into the two accounts.

Step-by-step explanation:

x = amount invested in the first account.

y = amount invested in the second account.

You start off with this equation

x + y = 1000

0.08x + 0.09y=86

Subtract both sides by y.

x=1000-y

Subsitude 1000 - x for x for the second equation.

0.08(1000-y)+0.09y=$86

Use the distributive property to solve for y.

80-0.08y+0.09y=86

80-0.01y=86

6=-0.01y

=-600

Subsitude -600 for y in the first equation and solve for x.

x-600=1000

x=1600

-600 and 1600 were invested into the two accounts.

The area of a right triangle is 270 square meters. The height of the right triangle is 15 meters. What is the length of the hypo
soldi70 [24.7K]

Answer:

\sqrt{549} ≈ 23.4

Step-by-step explanation:

A = bh

270 = 15b

b = 18

Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse:  a² + b² = c²

15² + 18² = c²

225 + 324 = c²

c² = 549

c = √549
