Answer:
(f • g)(3) = 100, the distance in miles the bus traveled
Step-by-step explanation:
The product of (miles/hour) and (hours) is (miles), so only answers with units of distance are applicable. The numbers are ...
f(3) = 2·3² +2 = 20 . . . . miles per hour
g(3) = 3+2 = 5 . . . . hours
so (f·g)(3) = f(3)·g(3) = 20·5 = 100 . . . . miles
This means only the first answer choice is applicable.
I believe the right equation for determining the area of a trapezoid is as below,
A = h(a + b)/2
To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.
2A = h(a + b)
Then, divide both sides of the equation by h,
2A/h = a + b
Then, subtract a from both sides of the equation,
2A/h - a = b
Lastly, interchange the sides of the equation to reveal the answer.
<em> </em>
<em> b = 2A/h - a </em>
Answer:
18 Pounds
Step-by-step explanation:
Variable: s=how much you sister weighs
One equation would be:
94 - s = 112
You then have to isolate the variable by subtracting 94 from each side to get:
s=18
I don't if I explained it that well.
Answer:
Less than
Step-by-step explanation:
Although it wasn't an option, it is less than. In order to accurately compare then, you have to get the least common denominator. Using the least common multiple (2), you multiply 5/8 by 2 and end up with 10/16. Now 10 is less than 11, so the option is neither of those. 5/8 is less than 11/16.
