Answer:
Total surface area of the given figure is 246.75 square mile.
Step-by-step explanation:
Surface Area of the given figure = Lateral surface area + Area of the base
Lateral surface area of the figure = Sum of the areas of 5 triangular surfaces
= 
= 
= 162.75 mi²
Surface area of the pentagonal base = 84 mi²
Total surface area of the figure = 162.75 + 84
= 246.75 mi²
Therefore, total surface area of the given figure is 246.75 square mile.
Answer:
y = -5/14x + 12
Step-by-step explanation:
add 14y to both sides to isolate variables and divide everything by 14 to get 1y and boom
-14W + 35. Can’t simplify any further
Answer:
12x - 6 ≤ - 18
Step-by-step explanation:
We will call "a number" x so
Twelve times a number would be:
12x
Then minus 6
12x - 6
Now we add the less than or equal to sign.
12x - 6 ≤
This is equal to negative eighteen, so:
12x - 6 ≤ - 18
As a bonus we can also solve for x.
12x - 6 = - 18 Add 6 to each side.
12x - 6 + 6 = -18 + 6
12x = -18 + 6
12x = -12 Divide each side by 12
12x/12 = -12/12
x = -12/12
x = -1
So we can say when x ≤ -1 Then 12x - 6 ≤ -18
First, we need to isolate the variable x.
To isolate x, we simply need to multiply both sides by 9, which would result in x = 9
