200/160=1.25
200+160=360/1.25/160=200.8
so your answer is 0.8
The tall of the actual building will be 216 feet
Step-by-step explanation:
An architect is presenting a scale model of a building she's designed
to the planning committee of college
1. The scale of the model is 1 inch = 18 feet
2. The tallest wall in the model is 12 inches
3. We need to know how tall the actual building will be
Let us used the ratio method
∵ The scale of the model is 1 inch represents 18 feet
∵ The tallest wall in the model is 12 inch
→ Model(in) : Actual(ft)
→ 1 : 18
→ 12 : h
- By using cross multiplication
∴ 1 × h = 12 × 18
∴ h = 216 feet
∴ The actual height is 216 feet
The tall of the actual building will be 216 feet

Answer:
x=6
Step-by-step explanation:
Step 1:
Subtract 3x from both sides:
4x + 8 - 3x = 3x + 14 - 3x
x + 8 = 14
Step 2:
Subtract 8 from both sides:
x + 8 - 8 = 14 - 8
x = 6
The volume of the square base pyramid is 588 ft³
The Volume of the rectangular prism is 120 ft³
The Volume of a rectangular pyramid is 360 ft³
<h3>What is volume of a shape?</h3>
Volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.
Volume of a square base pyramid = 1 / 3 × B × h
where
B = base area
Therefore,
Volume of a square base pyramid = 1 / 3 × 7² × 12
Volume of a square base pyramid = 1764 / 3 = 588 ft³
Volume of a rectangular prism = lwh
Volume of a rectangular prism = 6 × 5 × 4 = 120 ft³
Volume of a rectangular pyramid = 1 / 3 lwh
Volume of a rectangular pyramid = 1 / 3 × 10 × 12 × 9 = 1080 / 3 = 360 ft³
