Can some help meeeeeeeee?

Answer:

$46.54

Step-by-step explanation:

A=P(1+r/n)^nt

P=220

r=.0325

n=1

t=6

A=266.54

A=P+I

266.54=220+I

I=46.54

Answer the two questions below. THANKS!!

vivado [14]

Problem 1

We're given that angle A = angle B. Also that angle B = angle C.

By the transitive property, we can say angle A = angle C.

So basically all three angles are equal to one another. Let's call that unknown angle x.

For any triangle, the three angles always add to 180, so,

x+x+x = 180

3x = 180

x = 180/3

x = 60

That proves angles A,B, and C are each 60 degrees. This triangle is considered equiangular since all angles are the same. Furthermore, the triangle is also considered equilateral meaning all sides are the same. The term equilateral is more widely used, so I'd go with that term if you could only pick one.

==========================================================

Problem 2

As mentioned in problem 1, the three angles of a triangle add to 180

A+B+C = 180

A+B+90 = 180

A+B+90-90 = 180-90

A+B = 90

This shows A and B are complementary angles. Complementary angles by definition add to 90 degrees.

The moon is about 240,000 miles from the earth what is the distance right now as a whole number multiplied by a power of 10

sertanlavr [38]

240,000 = 24 x 10,000 but 10,000 = 10 x 10 x 10 x 10 = 10⁴, then:

240,000 = 24 x 10⁴

A number is doubled and then 1 is added to it. The answer is divided by 5 and then increased by 16. The final result is 18.

ipn [44]

So let's break down this sentence (Let n = unknown number):

"A number is doubled and then 1 is added to it"; Remember that double means multiplied by 2. With this sentence, we can determine that "2n + 1" is a part of the equation.
"The answer is divided by 5, and then increased by 16"; The "answer" they refer to is "2n + 1" from the prior sentence. Since this is divided by 5 and <em>then</em> added by 16, we can determine that $\frac{2n+1}{5}+16$ is a part of our equation.
"The final result is 18"; This means that the prior part of the equation is equal (=) to 18. <u>With this info, our full equation is $\frac{2n+1}{5}+16=18$ </u>

Now, let's solve our prior equation found in A. To solve for the unknown number, n, we need to isolate the variable onto 1 side of the equation. Firstly subtract both sides by 16 to cancel out the + 16 on the left side:

$\frac{2n+1}{5}=2$
