Im pretty sure number 15 is D
The correct answers are
a) 40%
b) 30%
1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2
2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2
Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2
Answer:
I believe it does
Step-by-step explanation:
sorry if i am wrong
9 - 3 ÷ 1/3 + 1
BODMAS says that the first thing we do in this is the division (D), so 3 ÷ 1/3 = 9
9 - 9 + 1
Now we do the addition, 9 + 1 = 10
9 - 10 = -1
So your final answer is -1, I hope this helps!
