Answer:
16
Step-by-step explanation:
The height of the triangle is 60cm, or 20cm+ 40cm.
The equation for area of a triangle is A=1/2bh
Your base is 30 cm height is 20cm.
A=1/2(30)(20)
A=1/2(600)
A=300cm^2
Your answer is 300cm^2
Company A = 111
Company B = 75 + 0.90m ( 75 plus 0.90 per mile)
Set the 2 to equal and solve for m ( miles)
111 = 75 + 0.90m
Subtract 75 from each side:
36 = 0.90m
Divide both sides by 0.90:
m = 36 / 0.90
m = 40
At 40 miles both Company A and Company B would cost the same.
So for Company A to cost less than Company B, you would have to drive more than 40 miles.
m>40
Answer:
75%
Step-by-step explanation:
3/4 = 75/100
It is 16x2-24x+9
So...you can put it into the form a2+2ab+b2=(a+b)^2
