Answer:
B (169)
Step-by-step explanation:
Answer:
length = 4 feet, and width = 2 feet
Step-by-step explanation:
Given that 12 feet of the frame material is available for the rectangular part of Norman's window. Then,
Perimeter = 2 (length + width)
Perimeter of the frame = 12 feet
So that,
Perimeter = 2 (length + width)
12 = 2 (length + width)
length + width =
length + width = 6 feet
Therefore, to allow much light as possible, the dimensions of the window would be; length = 4 feet, and width = 2 feet.
Given:
Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.
Solution:
Let the number of tulips and roses are 2x and x respectively.
According to the question,
Divide both sides by 3.
Now,
Number of tulips
Therefore, the number of tulips is 12.
Plant B is feet tall.
Step-by-step explanation:
Given,
Height of plant A =
This is 4/5 of height of plant B.
Let,
x be the height of plant B.
Multiplying both sides by
Plant B is feet tall.

Answer:
n = 60
Step-by-step explanation:
Solve for n:
(3 n)/5 = 36
Multiply both sides of (3 n)/5 = 36 by 5/3:
(5×3 n)/(3×5) = 5/3×36
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×36
5/3×36 = (5×36)/3:
(5×3 n)/(3×5) = (5×36)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×36)/3
