Answer:
d) 303 8/9
Step-by-step explanation:
4th term = ar^3 and 5th = ar^4 where a = first term and r = common ratio.
So ar^4 / ar^3
= r = 45/-15 = -3.
Working back,:
The first term a = ar^3/ r^3
= -15 / (-3)^3
= -15/-27
= 5/9
Sum of n terms = a * (r^n - 1)/(r-1)
= 5/9 * ((-3)^7 - 1 ) / (-3 -1)
= 303 8/9
Answer:
The answer is 97
Step-by-step explanation:
According to PEMDAS, we will solve the multiplication first. 2 × 42 is 84. Next, we will add or subtract from left to right. 9 + 84 + 6 – 2 is 97, the answer to our problem.
Answer:
2(u+3v)
2 times u is 2u and then 2 times 3v is 6v.
2u+6v
Answer:
1) $16.35
2) 75%
3) $245
Step-by-step explanation:
1) Jada earns = $15 per hour
9% increase = 15 * 9/100 = $1.35
Increased Jada's pay = 15+1.35 = $16.35
2) Markup = selling price - cost= $350 - 200= $150
Markup % = 
\
= 
= 75%
3) Jada's sister commission is 3.5% of $7000
= 
= $245
