Answer:

<u>The principal of the investment is $ 500</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Interests = $ 60

Interest rate = 12% annually = 0.12

Time = 1 year

2. Find the principal.

Let's use the formula given:

Interests = Principal * interest rate * time

Replacing with the real values, we have:

60 = Principal * 0.12 * 1

0.12 * Principal = 60

Principal = 60/0.12

Principal = 500

Dont understand this question it confucing
Juliette [100K]
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4.  So she's 75% of the time effective.

Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.

Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.

so, which fraction is highest 3/4, or 2/3 or 2/3?  neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.

so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

\bf 12\cdot \cfrac{3}{4}\implies \boxed{9}\qquad \qquad 12\cdot \cfrac{2}{3}\implies \boxed{8}

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.

Given that two sides of a triangle have sides 5 and 7, write the range of the lengths of the third side:
matrenka [14]

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range    is  2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.
