Answer:
It will take them 3.43 hours.
Step-by-step explanation:
Let T denote the total cookies that need to be cocked. Observe that:
- If Rosanne finishes the cookies in 6 hours, that means that she can make
cookies per hour. - If Dorothy finishes the cookies in 8 hours, that means that she can make
cookies per hour.
Then, by 1) and 2), if they work together would we able to make
cookies per hour.
Therefore, in order to finish the T cookies they will need 
Answer:
Step-by-step explanation:
<u>Compounded interest amount formula:</u>
<u>Given</u>:
- P = $956
- r = 6% = 0.06
- t = 12 years
- n = 4 and n = 1
1. <u>Compounded quarterly</u>
- A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.57
2. <u>Compounded annually</u>
- A = 956(1 + 0.06)^12 = 1923.66
The third option has like terms as they can be added based on the term. For example numbers with x, x^2, x^3 etc can be added together. For example x+x can be added but x+x^2 can’t. They have different terms that make them different.
Answer:
arrange it first in increasing order
42,55,69,74,78,83,83,97,99
n=9
we have
Q2=(n+1)/2th term=(9+1)/2th term=5thterm=78
