Suzette deposited $800 into a bank account earning simple interest of 2.5% each year. After 5 years, how much interest had her a
Blababa [14]

Answer:

\boxed {\boxed {\sf \$ 100.00}}

Step-by-step explanation:

The formula for simple interest is

I=prt

where <em>p</em> is the principal, <em>r </em>is the rate, and <em>t</em> is the time.

The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.

Divide by 100 or move the decimal place two spots to the left.

  • 2.5/100=0.025       or          2.5 ⇒  0.25 ⇒ 0.025

Substitute the known values into the formula.

p= 800 \\r= 0.025 \\t= 5

I= (800)(0.025)(5)

Multiply.

I=20(5)\\I=100

After 5 years, Suzette's account has earned $100.00

In the figure, m&lt;2 = 44. What is the measure of &lt;1?
fredd [130]

Answer:

m∠1 = 112°

Step-by-step explanation:

To solve for m∠1, we need to find the supplementary angle and subtract from 180°.  We also know that m∠2 = 44° and the remaining two angles inside the triangle are the same because of the congruent sides, let's call each angle x.

Therefore m∠2 + x + x = 180; combine x's

m∠2 + 2x = 180; substitute m∠2 = 44°

44 + 2x = 180; subtract 44 from both sides

2x = 136; divide by 2

x = 68°

Therefore using the supplementary angle

x + m∠1 = 180 (because it is supplementary)

68 + m∠1 = 180; subtract 68 from both sides

m∠1 = 112°
