The answer is the third one.
The way I think through these problems is that where you multiply (-7x), you use addition, and where you use addition (-4), you multiply.
The answers added together will equal the second number, -7, and multiplied will give you the third, -4.
What you had chosen as the answer was close. But 7.53+-0.53 equals positive 7, not negative. However they do round to -4 when multiplied.
The correct answer, -7.53 and 0.53, do equal -7 when added together and equal -4 when multiplied.
Answer:
3/4 or 6/8
Step-by-step explanation:
6/8 when simplified is 3/4. That is the probability over the total.
Answer:
Option A)
Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.
Combing the two equations, we get,
Now, removing the sign of proportionality and adding the constant of proportionality, we get,
where k is the constant of proportionality.
Thus, the correct answer is
Option A)
You would do percent of change.
meaning you would subract 65 and 50 to get 15. then you would put 15 over 50 (as a fraction) then equals r/100. then you would cross multiply to get r.
orginal:50
new:65
65-50=15
15/50=r/100
15r=5000
then divide by 15 to get r
