Answer:
B
Step-by-step explanation:
I believe that the answer to this question is B. I think this because I took 5.2 and divided it by 0.4 which gave me 13. I did 5.2 divided by 0.4 because it wanted to know how many times 0.4 goes into 5.2.
I hope this helps I am rlly srry if I am wrong. have a beautiful day.
Answer:
<h2>S.A. = 66m²</h2>
Step-by-step explanation:
Look at the picture.
We have :
4 rectangles 3m × 4m → A₁ = 3 · 4 = 12 m²
2 rectangles 3m × 3m → A₂ = 3 · 3 = 9 m²
Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
Substitute:
S.A. = 4(12) + 2(9) = 48 + 18 = 66
If c²=a²+b², it is a right triangle.
if c²<a²+b², it is a acute triangle.
if c²>a²+b², it is a obtuse triangle.
in this case, 19²=361, 10²+13²=269. 19²>10²+13², so it is an obtuse triangle.
