and the graphs of these functions are shown below.
Answer:
Well, the only thing you should do is to use the formula.
if the bases are: a, b
and the height is=h
Then, this is your formula, S=½(a+b)×h
Step-by-step explanation:
Aight,
100dm=10m
S=10m
now, the formula
10=½(2.1+1.9)×h===> 20=4h==> h=5m
Try 9:2 and 3:1 but I'm not sure if that's right or not
Answer:
18
Step-by-step explanation:
Honestly you can just use a calculator for this.
But if you want to know how to actually do it, multiplying something by a fraction is just dividing it by its reciprocal (just flipping the numerator and the denominator).
Therefore...
72/4 is 18, 72 x 1/4 = 18
Answer:
8x(6+7)
