19.50 divided by 3.25 is 6
6 family members in total.
The original price is $130
you should find out 19.5 is 15% of what number ( if he saved $19.5
so the 15% off sale was $19.5 less than the original price.) the answer will be :
19.5*100 /15 = 1950 /15= 130
good luck
Answer:
Step-by-step explanation:
Out of 292 drawn Americans over 21, 225 of them don't smoke. That means the rest of them are smokers:
So there are 292 - 225 = 67 smokers here.
We can then calculate the portion of Americans over 21 who smoke:
All 6 sides of a cube are squares and and all of these squares are of exactly the same size. Thus, find the area of a square of side 10 inches and then multiply your result by 6.
(10 in)^2 = 100 in^2; 6 times this is 600 in^2.
Convert this to square feet by mult. it by (1 ft^2 / 144 in^2):
(600 in^2)(1 ft^2) / (144 in^2) = (600/144) ft^2. Reduce 600/144 to lowest terms.
