Answer:
length = 27
breadth = 16
Step-by-step explanation:
The equation to determine the perimeter of the rectangle is given as
6x-10=86
the solution to above is x=16
Hence one of the side is 16. The formula for perimeter is given as
P=2(l+b)
if b=x =16
and P=86
replacing them inthe formula for perimeter
86=2(l+16)
dividing both sides by 2 we get
43=16+l
subtracting 16 from both sides we get
27=l
Hence the length and breadth of the rectangle are 27 and 16 respectively
Anna could have bought 3 boxes, which would serve 2 cupcakes to each child.
Answer:
<h2>A</h2>
Step-by-step explanation:
Subtracting 10x from the given equation gives
120 = 15x
Then dividing by 15 gives
8 = x
Zorah will have to play 8 hours in order to break even (cover her expenses exactly).
Using the together rate, it is found that the time it would take the second pump, working alone, to fill the tank is:
B. 90 minutes
The <em>together rate</em> is the <u>sum of each separate rate</u>.
In this problem:
- The together rate is of 1/60.
- The first rate is of 1/150.
- The second rate is of 1/x.
Then:
Applying cross multiplication:
Hence, it would take 90 minutes for the second pump, working alone, to fill the tank.
