Step-by-step explanation:
this month-100 percent
then previous month 100-20=80 percent
so
if 48=100percent
then x=80percent
x=(80×48)/100
x=38.4 ≈ 38 pairs if shoes
Answer: 84.09%
Step-by-step explanation:
1. 220-30=? ?=185
2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409
3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09
Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is

and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B
The mixed number will be 13 3/4.
for an isosceles right triangle the legs would be 2 times the square root of the hypotenuse
so for this:
the legs would be 2sqrt(10)
