Answer:
132 km^2
Step-by-step explanation:
For this type of question, we’re looking for the surface area (SA) for the shape.
To do this, use the surface area (SA) formula
SA = 2lh + 2lw + 2hw where l = length w = width & h = height
But before we go ahead, this formula is only used for triangular shapes. So what we’re going to do is find the surface area and then split it in half.
SA = 2(8)(6) + 2(8)(6) + 2(6)(6) / 2
SA = (2(48) + 2(48) + 2(36)) / 2
SA = (96 + 96 + 72) / 2
SA = 264/2
SA = 132
The surface area is 132 km^2
Answer:
18
Step-by-step explanation:
We can create a ratio of the amount of students who picked green over the total amount of students.
9 students picked the green pattern, and a total of 50 students were surveyed. This means the ratio is .
To turn into a percentage, we must divide it's numerator by it's denominator and multiply by 100.
So the green bar's height will be 18.
Hope this helped!
Answer:
x = - 7, x = 2
Step-by-step explanation:
Given
x² + 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)
The factors are + 7 and - 2, since
7 × - 2 = - 14 and 7 - 2 = + 5 , thus
(x + 7)x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
