Answer:
the answer will be 366:81
Step-by-step explanation:
you will find value of ratio 3:18
=6
then divide 366:61
=6
Answer: 1/4
Step-by-step explanation:
R * p = -37.8
Solve for either R or p.
R = -37.8/p
Now plug into R + p = 13.5
-37.8/p + p = 13.5
Solve for p.
After finding p, plug your p-value into either R + p or R*p to find R.
Take it from here.
Answer: 122.5
======================================================
Explanation:
First thing to do is to find the perimeter of figure B. Add up all the sides and we get: 5+9+9+12 = 14+21 = 35.
The scale factor 7:2 means that if the perimeter of figure A was 7, then the perimeter of figure B would be 2. Or it could be 14 for A and 4 for B. And so on. The idea is that the two perimeters scale up or down together. This allows us to set up the proportion below in which we can solve for x
(perimeter of A)/(perimeter of B) = 7/2
x/35 = 7/2
x*2 = 35*7 .... cross multiply
2x = 245
2x/2 = 245/2 .... divide both sides by 2
x = 122.5
The perimeter of figure A is 122.5
No, because then she would have to pay 21 dollars as a total and she only has 20.
Add adult plus Child,
5.75 + 11.25 = 17
add that to the book's price,
17+3.99= 2.99
it will exceed the budget by 99 cents.
