Answer:
48/b
Step-by-step explanation:
32÷16=2 so it takes two minutes per airplane. if she makes airplanes for 96 minutes at the same pace (2 min per airplane) then you need to divide 96 by 2 which gives you 48!
Answer:
14/20 is simplified to 7/10. 16/24 is simplified to 2/3 they are not proportional.
Step-by-step explanation:
(1/12) / (1/3) = 1/x....now just solve it like a proportion.....oh, and x represents the number of hrs it would take to fill the whole tank
form 2 equations
length=x
width=y
the equations are:
2(x+y)=82, because 82 would the the perimeter which is 2(l+w)
x=y+9
Now use substitution and you'll get y=16. Then plug in 16 and you'll get x=25. so the length is 25 and the width is 16.
Therefore the dimensions would be 25 by 16. Notice that the length, 25, is 9 greater than the width, 16. Also notice that a perimeter of a rectangle with length 25 and width 16 is 82 ( 2(25+16)=2(41) = 82))
Percent is the amount of something in a whole per amount of the whole times 100. To solve for this problem, we write an expression and assign x as the number that represents the number where 32.5% is equal to 12.48.
(32.5/100)x = 12.48
x = 38.4
