1/10*(f-220) or 0.1(f-220)
Answer:
18 inches and 9 inches
Step-by-step explanation:
Given, The base of a triangle is twice of the height.
Area = 81 sq inches
Let, Base (b) = 2x
Height (h) = x
Area of the triangle = \frac{1}{2}bh
\frac{1}{2}bh = 81
or, x^{2} = 8
Base = 2×9 inches = 18 inches
Height = 9 inches
6 millimeters equals 0.00656168 yards.
Answer:
She is doing a mistake of calculating interest after 9 months in place of after 12 months.
Step-by-step explanation:
Samantha deposit $300 in an account that earns an annual interest rate of 2.5%.

The calculation of interest should be on a yearly basis (i.e. 12 months) as the interest rate is 2.5% per year. (Answer)
First, you multiply 6 by 6, since one-sixth of all her dog toys are red.
6×6=36.
Next, we put them in fraction form just to check.

Next, we simplify it to see if we get one-sixth.
After it's simplified we get

That means she has
36 dog toys.
Have a nice day! :)
