The end answer is 40.75cm^2 (squared)
How i got there was i used the equation
1/2 (a×b ) + 3/2 (b×s)
where A is the height of the base triangle
Where b is the side length (it does not matter which one but it is one of the 5's)
The second b stands for the same thing.
Where S represents the height of the pyramid.
So then we get this:
1/2 (4.3 × 5) + 3/2 (5 × 4)
you solve the parentheses first and so on and so on.
I hope this helps!! Have a good day and remember to be tiger fierce!! :p
Answer:
mean will be find in that method
hence, correct option is B
Answer:
First building = 456
Second building = 438
Third building = 383
Step-by-step explanation:
First building = 73 + x
Second building = 55 + x
Third building = x
Total height of three buildings = 1277
(73 + x) + (55 + x) + (x) = 1277
73 + x + 55 + x + x = 1277
128 + x + x + x = 1277
128 + 3x = 1277
3x = 1149
x = 383
This is the height of the third building.
First building = 73 + x = 73 + 383 = 456
Second building = 55 + x = 55 + 383 = 438
1) b. There are 10 100's in 1,000
2) c. This is what it is written in words
