Your answer is B. 30. Here's why:

First, you do the parenthesis inside the parenthesis, which is 6 to the 2nd minus 4 to the 2nd. 6^2 is 36 and 4^2 is 16, and the difference is 20. Second we have 4x10÷20+1. With Order of Operations, you get 40÷20+1, then 2+1 and lastly 3. Finally after <u>these</u> parenthesis, you multiply by the 10 on the outside and your final answer, 30.

larisa86 [58]
First make the denominators of the fractions the same by multiplying.

\frac{2}{3} × \frac{2}{2}
=\frac{4}{6}

Now we just need to add the fractions together

\frac{5}{6} +  \frac{4}{6}
= \frac{9}{6}

9/6 would be the answer, but it can be simplified further, then converted into decimal form.

\frac{9}{6} ÷ \frac{3}{3}
=\frac{3}{2}
=1.5 yards

Your final answer is 1.5 yards of ribbon are needed.

Explain how to find simple interest
mr_godi [17]

Answer:

Simple interest is calculated by multiplying the daily interest rate by the principal, by the number of days that elapse between payments.

Step-by-step explanation:

Principal x rate x time = interest.

$100 x .05 x 1 = $5 simple interest for one year.

$100 x .05 x 3 = $15 simple interest for three years.
