Answer:
D) 36 bottles for $4 by 1.4¢ per bottle
Step-by-step explanation:
We calculate bottle per dollar for each option.
#A
Bottles/Dollar=
bottles/dollar
#Both B and C charges the same as A and will have bottle/dollar ration of 8:1
#D
Hence, D is the better buy as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.
Answer:
- 3 feet is the start point
Step-by-step explanation:
<u>Function given:</u>
- h(t) = −4.5t2 + 19.6t + 3
At t =0 we get h(0) = 3. This is called y-intercept
It is the start point indicating the disc was thrown at 3 feet height
The answer is the first one
Answer:x=-8
Step-by-step explanation:subtract 21 from both sides then simplify 31-21 to -8
Answer:
D. p + q = 7
Step-by-step explanation:
The slope of AB is ...
mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)
The slope of BC is ...
mBC = (q -1)/(9 -6) = (q -1)/3
We want the product of these slopes to be -1:
mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)
-(q-1)/(6 -p) = -1 . . . . cancel factors of 3
q -1 = 6 -p . . . . . multiply by -(6 -p)
q + p = 7 . . . . . matches choice D
