Answer:
The fabric needs 196.4 ft²
Step-by-step explanation:
∵ The tent formed formed from 4 faces
two equilateral triangles with side length 7 ft
two rectangles with dimensions 11 ft and 7 ft
∵ Area equilateral Δ = 1/4 S²√3
∵ Area rectangle = L × W
∴ The area of the prism = 2 × 1/4 × (7)²√3 + 2 × 7 × 11
= 196.4 ft²
Note:
If you find the area of the triangle by the rule 1/2 × base × height
∴ Area Δ = 1/2 × (7) × 6 = 21 ft²
∴ Area tent = 2 × 21 + 2 × 77 = 196 ft²
Two answer very closed
Answer:
11,000
Step-by-step explanation:
8,000 + 3,000
2nd or 3rd grade math!
5 5/32 as a decimal is 0.15265
Since 8 is half of 4, you can get the answer of 9×4 which is 36 and add it to itself which is 36+36 which gives you 72. Which is the same as 9×8.
Answer:
x = -1, 2
Step-by-step explanation:
Step 1: Write out equation
(x - 2)(3x + 3) = 0
Step 2: Solve each individual root
x - 2 = 0
x = 2
3x + 3 = 0
3x = -3
x = -1
Step 3: Arrange from least to greatest
-1 < 2
So x = -1, 2
