B. Because if she has to make a payment of $2,316 twice a year it would be $4,632. Then you divide that by how many months there are in a year so 12. Then you get B. $386
Answer:which one
Step-by-step explanation: which one 50
To solve this, set up a proportion with X being our unknown. If she cleans 12 houses in 10 hours, she cleans 27 houses in X hours. It will look like
.
Now cross-multiply to get 12x = 27(10) or 12x = 270. Divide by 12 on both sides to isolate x, X = 22.5.
It will take Kathy 22.5 hours to clean 27 houses. Must be some pretty small houses.
The first five terms of a sequence are 7,10, 13 , 16 and 19. which of the following functions define this sequence for all integers n>or equal to 1?
A. f[n]= 3n=7
B.f[n]= 4+3n
C. f[n]= 4[3]^n-1
D.f[n]=7[3]^n-1
Answer:
Option B is correct.
Step-by-step explanation:
Given:
The given sequence of an AP is.
7,10,13,16,19......
The first term of an AP
And common difference
The function which defined this sequence is;
Now we substitute a and d value in above equation.
therefore, the function for the given sequence for all integers 1 is;
