Answer:
A. 2564 cm^2
Step-by-step explanation:
There are two triangles (Which both are the same) and three different rectangles.
1. Let's solve the area of the triangles first!
Formula: bh(1/2)
10(26)(1/2)
130
2. Now, let's multiply by 2 since there's two of them:
130(2) = 260
3. So, we got 260. Let's find the area of the three rectangles!
Formula: bh
Rectangle A: 28(36) = 1008
Rectangle B: 10(36) = 360
Rectangle C: 26(36) = 936
4. Add the area of the triangles and the rectangles!
260 + 1008 + 360 + 936 = 2564
So the surface area is 2564 cm^2

Answer:
n=14
Step-by-step explanation:
-6=(n/-14)-5
-6+5 = n/-14
-1= n/-14
cross multiplication and striking of negative sign from both side.
n=14
Answer:
1 - 3.54 hours / total flight time - 4.54
2 - 15/22
Step-by-step explanation:
First, you need to find the speed of the plane for the rest of the flight.
In the last 2 hours, it flies 830 miles.
In the last 1/2 hour, it flies at 160 mph so it travels 80 miles.
So in the middle of the flight, it travels (830 - 80) = 750 miles in 1 1/2 hours
Speed = 500 mph
Now think about the whole flight. There is 1 hour at 160 mph plus x hours at 500 mph.
Distance = 160 + 500x = 1930
500x = 1770
x = 3.54 hours
Total flight time = x + 1 = 4.54 hours
Answer:
35000
Step-by-step explanation:
I don't know the first one but I do know that in 7 hours it will be 35000
54.16 is more precise because it has more digits
