Given:
A salesperson is paid $10 per week plus $8 per sale.
This week, the salesperson wants to earn at least $250.
To find:
The inequality represents the number of sales, s, the salesperson must make in order to meet that goal.
Solution:
Let s be the number of sales.
Fixed earnings = $10 per week
Earning on 1 sale = $8
Earnings on s sales = $8s
Total earnings = Fixed earnings + Additional earnings of sale
[tex]\text{Total earnings}=10+8s[/tex]
This week, the salesperson wants to earn at least $250. It means, total earning must be greater than or equal to 250.
[tex]10+8s\geq 250[/tex]
[tex]8s\geq 250-10[/tex]
[tex]8s\geq 240[/tex]
Divide both sides by 8.
[tex]s\geq 30[/tex]
Therefore, the inequality [tex]s\geq 30[/tex] represents the number of sales, s, the salesperson must make in order to meet that goal.
If Jo drives 357 miles and uses 17 gallons of gas how many miles per gallon did he get? How far could Jo go on 50 gallons of gas?
He got 21 miles per gallon, which mean he would be able to go 1,050 miles with 50 gallons of gas.
Answer:
(a) 21 miles per gallon. (b) 1050 miles.
Step-by-step explanation:
357 / 17 = 21 miles per gallon.
21 * 50 = 1050 miles.

Let g be the function given by g(x) = x^4-3^3-x. What are all values of x such that g'(x)=1/2
Answer:
The answer is "[tex]x= \frac{\sqrt[3]{3} }{2}[/tex]"
Step-by-step explanation:
Given:
[tex]\to g(x) = x^4-3^3-x \\\\\to g'(x) = \frac{1}{2}\\\\x=?[/tex]
Solve:
[tex]\to g(x) = x^4-3^3-x\\\\\to g(x) =x^4 -27-x \\\\\to g(x) =x^4 -x-27[/tex]
differentiate the above equation:
[tex]\to g'(x) = 4x^3- 1[/tex]
Given that:
[tex]\to g'(x)= \frac{1}{2}[/tex]
[tex]\to \frac{1}{2}= 4x^3 -1\\\\\to \frac{1}{2} +1= 4x^3 \\\\\to \frac{1+2}{2}= 4x^3 \\\\\to \frac{3}{2}= 4x^3 \\\\\to x^3 =\frac{3}{2 \times 4} \\\\\to x^3 =\frac{3}{8} \\\\ \to \bold{x= \frac{\sqrt[3]{3} }{2}}[/tex]

Answer:
The answer is 81
Step-by-step explanation:
prove me wrong
Answer:
Choice D
Step-by-step explanation:
For this you have to distribute the exponent on the outside to the inside. So we will multiply 4 and [tex]\frac{1}{4}[/tex]. That will equal 1. So now we have [tex](81^1)[/tex] and anything to the power of 1 is itself. So the answer is 81.
The population of a town decreases exponentially at a rate of 1.7% per year.
The population now is 250 000. Calculate the population at the end of 5 years
Give your answer correct to the nearest hundred.
Answer: 229,500 people to the nearest hundred
Step-by-step explanation:
Population decreases exponentially at 1.7% per year in a town that is currently 250,000 in number.
Population in 5 years = 250,000 * ( 1 - 1.7%) ⁵
= 250,000 * 0.917841286185143
= 229,460
= 229,500 people to the nearest hundred
Find the value of 9u - 6 given that -2u+2=6
Answer:
The value of 9u - 6 is -24
Step-by-step explanation:
Let us solve the question
∵ -2u + 2 = 6
→ Subtract 2 from both sides to move 2 from the left side to the right side
∵ -2u + 2 - 2 = 6 - 2
∴ -2u = 4
→ Divide both sides by -2 to find the value of u
∵ [tex]\frac{-2u}{-2}[/tex] = [tex]\frac{4}{-2}[/tex]
∴ u = -2
∵ The given expression is 9u - 6
→ Substitute u by -2 to find the value of the given expression
∴ 9u - 6 = 9(-2) - 6
∴ 9u - 6 = -18 - 6
∴ 9u - 6 = -24
∴ The value of 9u - 6 is -24

If all 3 drones have the same mass which one has the thr greatest acceleration?
Answer:
We conclude that the red drown has the greater the acceleration.
Step-by-step explanation:
Given
Given that all 3 drones have the same mass.
To determine:
Which drone has the greatest acceleration
From the figure, it is clear that the red drown has a steeper slope. We know that the steeper the slope of the line the greater the acceleration.
It is also visible the red drone has already covered 50 km in just 50 minutes speed, while the blue drone covered around 30 km in 50 minutes and the green drone is the slowest of all, covering less than 20 km in 50 minutes.
Therefore, we conclude that the red drown has the greater the acceleration.

Matt Ali deposited $25,000 in a savings account. The account earns 5.5 percent interest compounded daily. Use the formula “ Amount of $1.00 at 5.5 Percent compounded Daily”. A). What amount will he have in his account 28 later ? B.) How much will be compound interest ?
Answer:
A) Amount = $ 116,601.31
B) Compound Interest = $ 91,601.31
Step-by-step explanation:
Compound interest Formula
A = P(1 + r/n)^nt
Where
P = Initial amount invested = $25,000
r = interest rate = 5.5 %
n = Compounding frequency = daily
t = time in years = 28 years
A). What amount will he have in his account 28 years later ?
First, convert R percent to r a decimal
r = R/100
r = 5.5%/100
r = 0.055 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 25,000.00(1 + 0.000150685/365)^(365)(28)
A = $ 116,601.31
B.) How much will be compound interest ?
I = Amount - Principal
A(Amount ) = $ 116,601.31
P (principal) = $ 25,000.00
I = $ 116,601.31 - $ 25,000.00
I (interest) = $ 91,601.31
Two stores sell the same refrigerator for the same original price. Store A advertises that the refrigerator is on sale for 15% off the original price. Store B advertises that it is reducing the refrigerator’s price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal. Let p represent the refrigerator’s original price. Which equation models this situation?

what is the best decimal equivlanet to 3 9 100
Hey there!
“What is the best decimal equivalent to 3 9/100?”
3(100) + 9
3(100) = 300
300 + 9 = 309 ⬅️ solving for your numerator
100 ÷ 1 = 100 ⬅️ solving for your denominator
309 / 100 ➡️ 309 ÷ 100 = 3.09
Thus your answer is: 3.09 ☑️

3.1(g-7)-1=5.2 what is G
Answer:
g = 8.7
Step-by-step explanation:
3.1 (g - 7) = 5.2
Multiply by 3.1
3.1g - 21. 7 = 5.2
Add 21.7 to both sides
3.1g = 5.2 + 21.7
3.1g = 26.9
Divide both sides by 3.1
g = 26.9 / 3.1
g = 8.677 = 8.7
