The question is Let h(x)=2x+5 and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
the answer
</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12
</span>h(g(1.5))= 12
Answer:
poop
Step-by-step explanation:
The distance traveled, d = 2/5 miles = 0.4 miles.
The time taken to travel 0.4miles is given as, t = 1/4 hr = 0.25 hr.
Thus, the average speed, s = distance traveled divided by time taken.
i.e.
![\begin{gathered} \text{average speed = }\frac{distance\text{ traveled}}{\text{time taken}}\text{ = }\frac{0.4}{0.25}\text{ } \\ \text{average sp}eed\text{ = 1.6 miles/hr} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7Baverage%20speed%20%3D%20%7D%5Cfrac%7Bdistance%5Ctext%7B%20traveled%7D%7D%7B%5Ctext%7Btime%20taken%7D%7D%5Ctext%7B%20%3D%20%20%7D%5Cfrac%7B0.4%7D%7B0.25%7D%5Ctext%7B%20%7D%20%5C%5C%20%5Ctext%7Baverage%20sp%7Deed%5Ctext%7B%20%3D%201.6%20miles%2Fhr%7D%20%5Cend%7Bgathered%7D)
we can now go through the options and see the correct answers:
option A is correct because unit rate per hour is the same thing as average speed
option B is wrong because average speed is greater than 1mile/hr from our calculation above
option C is wrong because 13/5 gives us 2.6 miles/hr
option D is correct because the average speed is indeed greater than 1
option E is wrong because average speed is 1.6 miles/hr not 2 1/4 miles/hr
Thus, the answers are:
Option A and Option D
It would take them about 129.9 hours to deliver all of the paper, because if you divide 44 by 52 you get 0.846153... now multiply that by 150 and you get 129.9230... Now round that to the nearest tenth which is 129.9.
Hope this helps :-)
