Answer:
273.7
Step-by-step explanation:
first fine the sides that isn't the base.
triangle area formula: (b*h)/2
(14*9)/2 = 63
since there are 3 sides you multiply this by three.
63*3=189
then find the base.
same formula since its a triangle.
(12.1*14)/2 = 84.7
now add them both up:
84.7+189 = 273.7
hope this helps!
She used two trapezoids.
She put one trapezoid on top and one on the bottom.
The shape she ends up making is a hexagon.
0.3 is the decimal of 45/150
To change fraction into decimal you need the divide the denominator by the numerator.
So 150 divided by 45 is 0.3.
Answer:
4/3
Step-by-step explanation:
Using the formula of rise/run:
9-1 = 8
8-2 = 6
8/6 =4/3
Answer:
3/2
Step-by-step explanation:
Let it be
C (5;4) , A (2;1) ; B(7;6)
Suppose that C divide the line AB in ratio m/n from point A (AC is m, CB is n)
Use the formula xc=(m*xb+n*xa)/ (m+n)
5=(m*7+2n)/(m+n)
5m+5n= 7m+2n
2m=3n
m/n=3/2
