Answer:
Step-by-step explanation:
y=mx+b where m=slope and b=y intercept
m=(y2-y1)/(x2-x1)=(22-4)/(0+8)=2.25
y=2.25x+b, using point (0,22) we can solve for b
22=2.25(0)+b
b=22
y=2.25x+22 or stating it fractionally
y=9x/4+22
52 tests because you would multiply 28 by 100 then divide by 54. You would get 51.851, but you cannot have and 8th of a test, so you would round up
I think u have to do 120÷20=60
then 60×15=900
so he sold 900 flowers I'm not sure tho
Answer:
6%
Step-by-step explanation:
We have to calculate the interest rate in the note, we must follow the following steps, calculate the amount of time remaining from the year 2021, as follows:
interest is for 5 months i.e. from Aug 01 to Dec 31 for year 2021
, so it means it would be 5/12 months.
We have to calculate the interest as follows:
I = P * R * T
We replace:
200 = 8000 * R * 5/12
we solve for R
200 * 12/5 = 8000 * R
R * 8000 = 480
R = 480/8000
R = 0.06
Which means that the interest rate on the note is 6%
