The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
she can read a total of 0.83 pages a minute if she reads at the pace she was reading at because if you take the amount of pages she read (7.5) and you divide by the amout of minutes read (9) then you can see if she read at a constant rate she would read 0.83 pages a minute
2/3 yard= 1 pillow
To find the total yards needed for 8 pillows, multiply 2/3 yard per pillow by 8 pillows.
= 2/3 * 8
multiply numerators; multiply denominators
= (2*8)/(3*1)
= 16/3
convert to a mixed number
= 5 1/3 yards needed
ANSWER: 5 1/3 yards is needed to make 8 pillows.
Hope this helps! :)
Answer:
16cm
Step-by-step explanation:
Let the breadth = x
The length exceeds = x + 7
The breadth increased = x + 3
Because it said the length decreased by 4 so, the length would be:
x + 7 - 4 = x + 3
Original area:
We learn that:
area = length * breadth
x*(x+7) = (x+3)*(x+3)
x^2 + 7x = (x+3)^2
x^2 + 7x = x^2 + 6x + 9 (We also learn that (a+b)^2 = a^2 + 2ab + b^2
x^2 - x^2 + 7x - 6x = 9
x = 9 (so the breadth = 9)
The length = x + 7 = 9+7 = 16(cm)
Hope this help you :3
Answer:
Step-by-step explanation:
The $2,000 upfront payment by Hank means that the relationship between the total amount paid and the number of months elapsed is NOT linear. On the other hand, the girl's zero down payment indicates a linear, proportional relationship.
