Answer:
C. 2 5/8
Step-by-step explanation:
1 3/4 ÷ 1/2
= 3 1/2
3 1/2 × 3/4
=2 5/8
1. combining like terms you should get: -5x^4+5x^3-4x^2+17x-1
2. again combine all like terms to get: 15x^4+x^3+2x^2+15x+1
3. 5x^9+3x^8-x^7+16x^6+10x^5+x^4-5x^3+33x^2-16x
Answer:
Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence
We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56
56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula
Answer:
88:56 = 11:7
Step-by-step explanation:
Step One
Add the two ratios together 11 + 7 = 18
Now set up a ratio to solve for 11 parts out of 18
11:18 = x:144 Proportion
11 / 18 = x / 144 Equation: Cross mulitiply
11*144 = 18x Combine the left side
1584 = 18x Divide by 18
1584 / 18 = x
88 = x
That is the larger amount (11 is larger than 7)
Find the smaller amount
144 - 88 = 56
The two amounts are in the ratio of 11:7
88:56 = 11:7
I hopes this helps a little bit
The total is $87.2 you have to first change the percentage to a decimal so 0.09x80=87.2
