Answer:
Area: 3.7 ft²
Ratio: 73.14 : 1
Step-by-step explanation:
Perimeter of an octagon = 8*side
Replacing with perimeter = 7 ft:
7 = 8*side
side = 7/8 ft = 0.875 ft
that is, each side of the model is 7/8 ft length.
Area of an octagon = 2*(1 + √2)*side²
Area of an octagon = 2*(1 + √2)*(7/8)²
Area of an octagon = 3.7 ft²
Perimeter of real gazebo = 8*8 = 64 ft
Then, the ratio of the perimeters (in feet) of the real gazebo floor to the model gazebo floor is 64:0.875. Multiplying each term by 8/7, we get 73.14:1
Answer:
<u>x = 12</u>
Step-by-step explanation:
10 - 3 ( x + 7 ) = 26
<em>First Step: Distribute</em>
- 3 to ( x + 7 )
= 10 - 3 x - 21 = 26
<em>Second Step: Combine like terms</em>
10 - 21
= - 11 - 3 x = 26
<em>Third Step: Add from both sides</em>
26 + 11
= - 3 x = 37
<em>Fourth Step: Divide from both sides</em>
37 / - 3
<u>x = 12</u>
Answer:
3/4 gallon of purple paint left
Step-by-step explanation:
3/8 + 5/8 =8/8
he uses 2/8 so
8/8 - 2/8 = 6/8
3/4 (simplified)
