Answer:
Step-by-step explanation:
Givens
- The railing will begin at 36 inches height.
- The slant decreases 9 inches for every 12 horizontal inches.
According to the problem, the slant is
The initial condition of the function is 36, which is a constant. Also, the slant is negative, because the problem states that "decreases".
If we see the problem form the perspective of a linear function, the constant ratio of change would be the slant.
Therefore, the linear function that models this problem is
So, the answer is the first choice.
The syntax for the IF statement is as follows:
=IF(condition, value if true, value if false)
therefore, we can enter the information from the problem:
=IF($B$9>=470000,35000,1000)
Answer:
answer a. 12 times 14 give us 168 minutes.
answer b. 42/14 = 3 tires
Step-by-step explanation:
You can do this problem a couple of ways.
Since we have two different forms of problems, let's solve for per minute of each tire.
a. 56/4 gives us time per tire in minutes.
14 minutes per tire
3 vans have 12 tires.
answer a. 12 x 14 give us 168 minutes.
b.
divide 42 minutes by 14 minutes to see how many tires he can fit.
answer b. 42/14 = 3 tires
