Answer:
direct variation
constant = 1/7
Step-by-step explanation:
The equation for direct variation is
y = kx
y = 1/7 x is in this form with the constant of variation being 1/7
First we need to find the common ratio by dividing the second term by the first term. 36/120 = 3/10
an = a1 * r^(n-1)
n = term to find = 5
a1 = first term = 120
r = common ratio = 3/10
now we sub and solve
a5 = 120 * 3/10^(5 - 1)
a5 = 120 * 3/10^4
a5 = 120 * .0081
a5 = 0.972 <=== fifth term
or we could have just done this......since we multiply by 3/10 to find the next number...
a3 = 10.8......10.8 * 3/10 = 3.24 <== 4th term
3.24 * 3/10 = 0.972 <== fifth term
Answer:76 D 77 C
Step-by-step explanation:
Your looking for W wholesale
Store originally has the price for $189 but mark it up 45%
189x0.45 = 420 ;)
1/10•2=0.2 (2 being n)
0.2 is the max amperage for house circuit 1
House circuit2 has 3 bulbs .3amps
1/10•N=I
1/10•3=.3
39 depending on the prices but 39 is how many he sold
810
Step-by-step explanation:
multiple 3x3 9 then multiple 3x9 27 multiply 27x3 equal 81 then add zero 810
