So the formula for area of a triangle is base * height / 2.
(In this case the height could be the altitude)
So if we rotate the shape, so line AC is the base, we can therefore clearly see what the height and length are.
If we count it, the line AC would equal 5 segments and the line BD would equal 3 segments.
So, 5 * 3 / 2
Or,
15/2
Which is 7.5.
So your answer is 7.5 square units.
4.92.
4 is a whole number, so it goes in the ones place
The ths means it is going to be a decimal, so 92 goes two right of the decimal point. Hope this helped
Answer:
Step-by-step explanation:
1)
y is 3 times more than x.
X=0 Y=0 3x0=0
X=1 Y=3
X=2 Y=6
X=3 Y=9
X=4 Y=12
Then just plot it as co-ordinates (x,y)
2)
Y is 1/4 of x. Divide by 4
X=0 Y=0
X=4 Y=1
X=8 Y=2
X=12 Y=3
X=16 Y=4
Then just plot it as co-ordinates (x,y)
0.68 = 0.6 + .08 = 6 x 0.1 + 8 x .01
They should all equal 0.68 :)
7.3 x 10^22 x 26,000,000=1.898x10^30
Mass of the sun= 1.898 x 10^30
