Hi 0101sj,
Your Question:
Avril types essays for students from her home. On average, she can type a page in about 10 2/3 minutes. she spends 54 1/2 minutes typing on essay, how many pages if this essay?
Answer:
1 PAGE = 10 2/3 = 10.20
Essay = 54 1/2 = 54.50
54.50 / 10.20 = 5.34313...
She approximately wrote 5 pages.
3 x 50 = 150
150 x 1.25 = 187.5
If you were to buy just brats, you would spend $187.50. So, you would have a spare $12.50, which could buy you 8 more.
3 x 50 = 150
150 x 0.95 = 142.5
If you were to buy just hamburgers, you would spend $142.50. So, you would have a spare $57.50, which could buy you 60 more.
Answer:
10000
Step-by-step explanation:
10 has 1 zero. 1000 has 3 zeros. Put these zeroes together to get 0000. Add one to the left, and you get 10000.
In this case the temperature depends on the hour. So temperature is your X and hour is your Y variable. When h=0, x=0. So the 21*C is you x=0 or y-int point.
If we are trying to match the equation for a line of y=mx+b, 21*C=b.
Our rate of change is -4*C/h, which is our m variable.
So y=(-4)x+(21)
OR in this case, t=-4h+21.
Answer D.
None of the above. The first two are slope-intercept, whereas the third one isn't a form.
