You want to put $8,000 in a simple interest account. It has a 2% annual interest rate. How long must you invest that money to ea

balandron [24]

Dear Sadaadams73, to solve this problem, we use the formula I=Prt. The equation will look like 400=8000 x 0.02 x t. Multiply 8000 by 0.2 to get 1600t=400. Then divide both sides by 400 to get 4 years.

Aaron and noah wanted to have a contest to see which of their paper airplanes could fly the longest distance. Aaron's plane flew

Marina CMI [18]

Aaron's plane flew 3.21 meters further than Noah's plane.

Explanation

Aaron's plane flew 4 meters and Noah's plane flew 79 centimeters.

So, first we need to convert 79 centimeters into meters.

We know that, 1 centimeter = 0.01 meter

So, 79 centimeters = $(0.01*79)meter= 0.79 meter$

Now, the difference of distance between Aaron's plane and Noah's plane is $(4-0.79) meters = 3.21 meters$

Find Y. Round to the nearest tenth.

Dennis_Churaev [7]

Answer:

Y ≈ 59.0°

Step-by-step explanation:

Using the Cosine rule

cosY = $\frac{x^2+z^2-y^2}{2xz}$

with x = 22, y = 20, z = 18

cosY = $\frac{22^2+18^2-20^2}{2(22)(18)}$

= $\frac{484+324-400}{792}$

= $\frac{408}{792}$ , then

Y = $cos^{-1}$ ( $\frac{408}{792}$ ) ≈ 59.0° ( to the nearest tenth )
