Answer:
<em>5 meters must be added to both the length and the width</em>
Step-by-step explanation:
<u>Area of a Rectangle</u>
A rectangle of width W and length L has an area calculated as:
A = W*L
Initially, the lot has a width of W1=25 m and a length of L1 = 120 m, thus its area is:
When adding x meters to the width and the length, the new area is:
Operating:
We now calculate the increased area by subtracting A2-A1:
We are given this area is 750 square meters, thus:
Rearranging:
Factoring:
Solving:
x=5, x=-150
Taking the positive solution x=5:
5 meters must be added to both the length and the width
Answer:
40%
Step-by-step explanation:
Probability that student is a male Given that it's a senior ::
Recall :
P(A | B) = (AnB) / B
Hence, we have ;
P(male | Senior) = number of (Male n Senior) / total Senoirs
From the table :
Total seniors = 2 + 3 = 5
Male n Seniors = 2
P(male | Senior) = 2 / 5 = 0.4 = 40%
Answer:
6:60 or 1:10 if it must be simplified
Step-by-step explanation:
Marco has ( d + 14.55 ) $
Step-by-step explanation:
Marco's mom gave him d dollars for his allowance one week.
Allowance of one week = d $
He also earned $ 1 4 . 5 5 for his newspaper route that week.
Earning of Marco by selling newspaper route that week = 14.55 $
Total earning = Allowance of one week + Earning of Marco by selling newspaper route that week
Total earning = ( d + 14.55 ) $
So Marco has ( d + 14.55 ) $
In this case, the complement would be selecting a number less than or equal to 7; the probability of this occurring is
