Answer:
The length is 48
The width is 20
Step-by-step explanation:
When 2 rectangles (figures) are similar, the ratio of corresponding sides are equal.
This rectangle is 5 by 12, so the shorter side (corresponding to 5) to the longer side (corresponding to 12) would be the same ratio, 5:12.
Let shorter side be s, and
longer side be l
It says, long side is 8 greater than twice short, we can write this as:

In similar rectangles, we have said the corresponding sides' ratio are equal, so we could write:

Now, we replace the new found expression for "l" onto this and cross multiply and solve for s first:

So the shorter side is 20. and hence the longer side would be:
l = 2s + 8
l = 2(20) + 8
l = 40 + 8
l = 48
The longer side is 48.
The length is 48
The width is 20
Answer: 3/5
Step-by-step explanation:
1. Multiply 30 by 3 (90)
2. 90 becomes the numerator and 150 becomes the denominator
3. Divide the numerator (90) and the denominator (150) by the greatest common factor (30), to simplify the fraction
4. You should come to the answer 3/5
Hope this helps.
Answer:
A typical mixture equation
:
x + .10(54-x) = .20(54)
x + 5.4 - .10x = 10.8
x - .1x = 10.8 - 5.4
.9x = 5.4
x = 5.4%2F.9
x = 6 L of pure acid to be combined with: 54-6 = 48 L of 10% solution
