The given sides are 12 cm, 15 cm and 21 cm
Shortest side is 12 cm
As given that in real the shortest side is 200 m
So 12 cm=200 m
then 1 cm = 
Hence 15 cm = 
m
21 cm = 
m
So,,
15 cm in the photograph is 250 m long
.
21 cm in the photograph is 350 long.
Answer:
vol = 96
Step-by-step explanation:
Area of a triangle = 1/2 * b * h
b = 4
h = 6
A = 0.5 * 4 * 6
A = 12
length = 8
vol = Area * length
vol = 12 * 8
vol = 96
Answer: It's 4
Step-by-step explanation: 12-8 is 4, 4-3 is 1
Answer:
x = 15
Step-by-step explanation:
The angles shown are supplementary angles. Supplementary angles add up to equal 180°
This means that 2x + 8 + 8x + 22 must equal 180
Note that we've just created an equation that we can use to solve for x
We now solve for x using that equation
2x + 8 + 8x + 22 = 180
combine like terms : 2x + 8x = 10x and 8 + 22 = 30
10x + 30 = 180
subtract 30 from both sides : 30 - 30 cancels out and 180 - 30 = 150
10x = 150
divide both sides by 10: 10x / 10 = x and 150 / 10 = 15
we're left with x = 15
Answer:
one-sixth of 138
Step-by-step explanation:
36÷3=12. 138÷6=23
12<23
Therefore, one-sixth of 138 is greater than a third of 36.
