The ratio of the model's height to actual height of tower is 1:725
Step-by-step explanation:
Given
Actual height of Sears Tower = = 1450 feet
Height of Model = = 24 inches
We can divide the actual height by the model's height to find the scale
Let z be the ratio of the height of the model to the actual height
The ratio should be in same unit.
We know that
1 ft = 12 inches
Then
Hence,
The ratio of the model's height to actual height of tower is 1:725

Length (L): L
width (w): 43
Perimeter (P) = 2L + 2w
178 = 2(L) + 2(43)
178 = 2L + 86
92 = 2L
46 = L
Answer: length = 46 centimeters
Answer:
She needs 112 ounces of Solution A and 48 ounces of Solution B.
Step-by-step explanation:
If a is the ounces of Solution A, and b is the ounces of Solution B, then:
a + b = 160
0.45a + 0.95b = 0.60(160)
Solve the system of equations. Using substitution:
0.45a + 0.95(160 − a) = 0.60(160)
0.45a + 152 − 0.95a = 96
56 = 0.5a
a = 112
b = 48
She needs 112 ounces of Solution A and 48 ounces of Solution B.
Answer:
x =7
Step-by-step explanation:
2x+6 = 20
To solve this equation, you first need to subtract 6 from each side
2x+6-6 = 20-6
2x = 14
Then divide each side by 2
2x/2 = 14/2
x = 7
