Answer:87.5
Step-by-step explanation: I can find the total cost of a 5 hire bike tour because I'm given the unit rate and the amount of time to multiply it by.
Step-by-step explanation:
(3x+5)-(4x²-2)-(x²-3x+1)
= 3x+5-4x²+2-x²+3x-1
=6x+6-5x²
=-5x²+6x+6
All integer numbers are either even or odd. So, the complement to the set B (to the set of all even integers) is the set of all odd integers, that is D.
The integer number of the form 2x is always even, because it is always divided by 2, so the set C is the empty set.
Numbers 1, 3, 5, 7 are odd, therefore they belong to the set D.
Answer:
x=13 feet
Step-by-step explanation:
A ramp is between 1.96 and 1.80 feet, we will take 1.96
and R(x)=1.96 feet: we apply quadratic formula; 
, where a=-0.05, b=0.8 and c=-1.96, so
solving 
; we take the highest value of x, x=13
Answer:
I would agree with your answer
Step-by-step explanation:
Though it's kind of comparing apples to oranges as the basis is unclear
I'm ASSUMING both investments occurred during the same time period.
The first one appears to have a ROI of 305/800 = 0.38125
The second one is much muddier
If the investment is cashed out to zero and the total return to you is $900, then the ROI is (900 - 650) / 650 = 0.3846153. This is better than the first return, but just a little bit.
However, if the investment has not been cashed out and your $650 is actually still working and you have received $900 in interest or dividends, then the ROI is 900/650 = 1.384615... which is more than 3.6 times greater return than the first option.
