8. Multiply the following:
c. (3s^4)(-6s^5)
The result of the multiplication is (-18s^9).
To multiply the two expressions (3s^4)(-6s^5), you can use the distributive property, which states that you can multiply a term by each of the terms inside a set of parentheses.
Using the distributive property, you can rewrite the expression as:
(3s^4)(-6s^5) = 3s^4 * -6s^5
Then, you can simplify the expression by combining like terms:
3s^4 * -6s^5 = (-18s^9)
So the result of the multiplication is (-18s^9).

Shaun is painting a fence. After finishing three-eighths of the length of the fence he finds that
he has painted 15 feet. Let f be the total length of the fence, set up an equation like one of
those in 4(b) and solve to find f. Use either of the two methods.
Answer: F = 40
Step-by-step explanation:
*Important: I do not know what the methods mentioned in 4b are, nor do I know its equation. Please take this into account.
What we know:
3/8 is equal to 15 ftF is the total amount of fence paintedWe need to set up and solve the equationHow we do this:
Using basic division, this equation is solveable.
Process:
Divide to find 1/8 15/3 = 5 (1/8f = 5)Multiply to find total 5 x 8 = 40(1/8 x 8 = 8/8)
Solution:
F = 40
8(5) = F
Answer: x = 40
Step-by-step explanation:
let f be the total length of the fence:
(3/8)f = 15
divide both sides by 3/8
f = 15 x 8/3
f = 120/3
f = 40
which is shorter 8ft or 95in !?
Answer: 95 in is shorter
Step-by-step explanation:
there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft

Answer:
40%
Step-by-step explanation:
Her monthly paycheck was 120 dollars, because thats how much she earned that month. If she saved 48 dollars, then the percentage of the paycheck she saved is the percent of 120 that is 48 dollars, or 48/120. Simplifying, we have 2/5, (because you can divide both the top and the bottom by 24), and 2/5 is equal to 40%

Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.
What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?
It would be y=x or x=y as we can see that 9 lawns in 9 hrs equal 1 lawn in 1 hr. 6 lawns in 6 hrs equals to 1 lawn in 1 hr as well.

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.
Part A: How much did Ron pay in sales tax? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.
Answer:
A. $2.00
B. $26.99
Step-by-step explanation:
0.5 x 49.99 = 24.995
49.99 - 24.995 = 24.995
0.08 x 24.995 = 1.9996 and round to the nearest hundredth
24.995 + 1.9996 = 26.9946
round to the nearest hundredth
Answer:
Part a: 1.9996
Part b: 26.9946
Step-by-step explanation:
STEP 1:
Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.
STEP 2:
Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).
STEP 3:
Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).
