36+28 because 4(9+7) = 64 and to get this answer you do 4*9 + 4*7 = 36 + 28 = 64
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
So multiplication first, 56*2= 112
Division second, 5/5=1
Subtraction last, so 112 - 1 = 111
111 is the answer.
From fraction to decimal: divide the numerator by the denominator
From decimal to percent: move the decimal two places to the right. For example: 0.062=6.2%
From percent to decimal: move the decimal point two steps to the left. For example: 56%=0.56
From decimal to fraction: Rewrite the decimal number number as a fraction (example: <span>2.625=<span>2.6251</span></span>) an then Multiply by 1 to eliminate 3 decimal places, we multiply numerator and denominator by 10 cubed = 1000<span><span><span>2.625/1</span>×<span>1000/1000</span>=<span>2625/1000 and don forget to reduce if possible;)

The formula for the circumference of a circle is 2•Pi•R (radius)or Pi•D (diameter).
Since we have the Radius, 5, let's use the 2•Pi•R path.
Pi is defaultly used as 3.14
Plug in 5 for R.
2 • 3.14 • 5
2• 5 = 10
10 • 3.14 = 31.4
The circumference of your circle is 31.4 CM.
Answer: 31cm
I hope this helps!
multiply 80 by 0.75
80 x 0.75 = 60
since you didn't add the chart to the question, which runner only ran 60 miles?
