Answer:
h=A/(a+b)
Step-by-step explanation:
Divide by a+b on both the sides.
A/(a+b)=((a+b)h)/(a+b)
h=A/(a+b)
Answer:
Step-by-step explanation:
Perimeter of a rectangle is expressed as (2 length + 2 width) = 2(L + W)
A) The length of rectangle A is y + 1
The width of rectangle A is x
Perimeter of rectangle A = 2(y + 1 + x) = 2y + 2 + 2x
= 2x + 2y + 2
The length of rectangle B is 2x - 2y
The width of rectangle B is x + 1
Perimeter of rectangle B = 2(2x - 2y+ x + 1) = 4x - 4y + 2x + 2) = 4x + 2x - 4y + 2
= 6x - 4y + 2
The length of rectangle C is 3x + 3y
The width of rectangle C is 2x - 3
Perimeter of rectangle C = 2(3x + 3y + 2x - 3) = 6x + 6y + 4x - 6) =
(6x + 6y + 4x - 6)
= 10x + 6y - 6
B) The combined perimeters will be the sum if perimeter of rectangle A, perimeter of rectangle B and perimeter of rectangle C. It becomes
2x + 2y + 2 + 6x - 4y + 2 + 10x + 6y - 6
Collecting like terms
2x + 6x + 10x + 2y + 6y - 4y + 2 + 2 - 6
The combined perimeter = 18x + 4y - 2
Zero! Who could possibly a Red Sox Fan when the Yankees are in town? Let them mourn the loss of the Babe forever!
Now you have a group of 20 and a group of 15. What you are being asked is what is the smallest number that you could find that can be divided evenly by 15 and 20? Is it 20 * 15=300 or is it something smaller.
The way to solve this is to write out the factors of 15 and 20.
15 = 3*5
20 = 2 * 2 * 5
So the smallest number is
one 3
two 2s
one 5 Don't count these 5s twice.
LCM = 3 * 2 * 2 * 5
LCM = 60.
The smallest group she could see of Yankee Fans and Red Sox Fans is 60 if they both must be equal.
Answer 60 Red Sox Fans.
The mean of the new data set is 2.76, and the range of the new data set is 1.5.
The answer is C and D. From the result, we can use this to represent the whole customer. But the percent calculation need to use the number of customers divided by total of 75, not 100.
