Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ <u>-x - 6y = 7</u>
2y = 18
y = 9
half of 9 = 4 1/2
100
I got the answer by 26 divided by 0.26
Answer:
The answer is A
Step-by-step explanation:
By looking at the graph, the y-intercept is -1. So, the answer must be A or C.
Then we can look at the the graph, you can see the line is left up right down. So the equation will be negative, which is A.
Answer:
lateral area ≈ 668 m²
surface area ≈ 740 m²
Step-by-step explanation:
The lateral area of a triangular prism = perimeter of the base × height of the prism
lateral area = ph
where
p = perimeter of the base
h = height or altitude
Base edges are 8m , 9m and 12.04m and height is 23 m.
lateral area = ph
lateral area = (8 + 9 + 12.04) × 23
lateral area = 29.04 × 23
lateral area = 667.92 m²
lateral area ≈ 668 m²
Surface area
surface area = lateral area + 2B
where
B = area of it triangular bases
surface area = lateral area + 2B
surface area = 667.92 + 2(1/2 × base × height)
surface area = 667.92 + 2(1/2 × 8 × 9)
surface area = 667.92 + 2(1/2 × 72)
surface area = 667.92 + 2(36)
surface area = 667.92 + 72
surface area = 739.92
surface area ≈ 740 m²
