Answer:
The bridge is 80 feet long
Step-by-step explanation:
We will use the ratio method to solve the question
∵ The engineer used the scale 3 inch = 40 feet
∴ The scale drawing is ⇒ 3 inche : 40 feet
∵ The drawing length of the bridge is 6 inches
→ By using the ratio method
→ inch : feet
→ 3 : 40
→ 6 : x
→ By using cross multiplication
∵ 3 × x = 6 × 40
∴ 3x = 240
→ Divide both sides by 3
∴ x = 80
∵ x represents the actual length of the bridge
∴ The bridge is 80 feet long
Answer:
Equal to
Step-by-step explanation:
Hello!
Let's simplify the left side:
Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.
Let's simplfy the right side:
Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.
So the inequality is 9 _ 9
Therefore the sign should be "=" as 9 is equal to 9.
Answer: 95 feet
Step-by-step explanation:
Let the length of the horizontal run be represented by x.
Slope Grade = (Rise/Run) × 100
20 = (19/x) × 100
20 = 1900/x
20x = 1900
x = 1900/20
x = 95
Therefore, the length of the horizontal run must be 95 feet
