Answer:
x = 4.363636...
Step-by-step explanation:
Set up a ratio
6 miles : 55 minutes
x miles : 40 minutes
Cross Multiply
55x = 40*6
55x = 240
55x / 55 = 240 / 55
x = 4.363636...
Answer:
82%
Step-by-step explanation:
because you have to divide 41 by 50 then,move the decimal 2 places to the right.
You essentially have four triangles. The area of a triangle is: A=bh/2 (b=base length and h=height)
So the area is simply the sum of the four triangle areas...
A=(3*2)/2+(3*2)/2+(7*2)/2+(7*2)/2
A=20 ft^2
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
