0 is greater than or equal to 7n
Final answer:
To solve the inequality 0 is greater than or equal to 7n, divide both sides by 7 to get n ≤ 0. This implies n can be any number less than or equal to zero.
Explanation:
The question asks us to solve the inequality 0 is greater than or equal to 7n. This involves understanding inequalities and basic algebraic manipulation. To solve for n, we divide both sides of the inequality by 7, keeping in mind the rules regarding dividing by a positive or negative number. Since 7 is positive, the direction of the inequality remains the same. Thus, we get n ≤ 0.
This means that n can be any number less than or equal to zero for the inequality to be true. It's an important fundamental of algebra that assists in understanding how to work with inequalities and solve them correctly.

I need to increase my sales by 35% this month I’m currently at 45 sales how many sales do I need to meet my goal ?
Answer:
61 sales.
Step-by-step explanation:
Let x represent present sales.
We have been given that you need to increase your sales by 35% this month. You are currently at 45 sales.
To find the number of sales to meet the goal, we will find 35% of 45 and add to 45 as:
[tex]\text{The number of sales to meet the goal}=45+\frac{35}{100}*45[/tex]
[tex]\text{The number of sales to meet the goal}=45+0.35*45[/tex]
[tex]\text{The number of sales to meet the goal}=45+15.75[/tex]
[tex]\text{The number of sales to meet the goal}=60.75[/tex]
[tex]\text{The number of sales to meet the goal}\approx 61[/tex]
Therefore, you need to make 61 sales to meet you goal.

Grady's payements or wages for hourly is increased by 8 percent.
What is percent?A Percentage or percent, a relative value indicating hundredth parts of any quantity.
How to caluclate increase in percent?To calcualte the increase in percentage first we subtract the original value from the new value, then divide the result by the original value. Multiply the result by 100.
According to the given question.
The intial payment for one hour was $10.50
And, after one hour the payment is $11.34
⇒ The increment in the payment = $11.34 - $10.50 = $0.84
Therefore,
the percent increase in Grady's hourly wage

Laticia randomly selected 25% of the seventh grade students in her school and asked them their favorite season. Of the students surveyed, 51 chose summer as their favorite season. Based on the data, what is the most reasonable prediction of the number of seventh grade students in her school who would choose summer as their favorite season?
A) 15
B) 75
C) 150
D) 200
The most reasonable prediction of the number of seventh grade students in her school who would choose summer as their favorite season is 75.
To predict the number of seventh-grade students in Laticia's school who would choose summer as their favorite season, we can use the fact that she surveyed 25% of the seventh-grade students and found that 51 of them chose summer.
First, we need to find out how many seventh-grade students there are in total. Since Laticia surveyed 25%, we can set up a proportion:
[tex]\[\frac{51}{25\%} = \frac{x}{100\%}\][/tex]
Solving for x, the total number of seventh-grade students, we get:
[tex]\[x = \frac{51 \times 100\%}{25\%} = 204\][/tex]
Now, since 51 students chose summer as their favorite season out of 204 seventh-grade students, to find out how many students might choose summer if all seventh-grade students were surveyed, we can set up another proportion:
[tex]\[\frac{51}{204} = \frac{y}{100\%}\][/tex]
Solving for y, the number of students who might choose summer if all seventh-grade students were surveyed:
[tex]\[y = \frac{51 \times 100\%}{204} = 25\%\][/tex]
This comes out to (y = 51), which means if all seventh-grade students were surveyed, we could reasonably predict that 51 of them would choose summer as their favorite season. Therefore, option B) 75 is the most reasonable prediction.

What is the equation of the translated function?
A. f(x) = (x – 1)2 – 5
B. f(x) = (x + 1)2 + 5
C. f(x) = (x – 5)2 – 1
D. f(x) = (x + 5)2 + 1
Yes the answer is B
The translated function is f(x) = (x - 1)² + 5.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
The vertex of the original function = (0, 0)
The vertex of the translated function = (-1, 5)
Now,
f(x) → f(x + a) represents a horizontal translation of f(x)
If a > 0 then a shift to the right of a units
If a < 0 then a shift to the left of a units
Vertex = (-1, 5)
This means the translated graph has been shifted to 1 unit left.
So,
f(x) = (x - 1)²
Now,
f(x) → f(x) + c represents a vertical translation of f(x)
If c > 0 then a shift up of c units
If c < 0 then a shift down of c units
Vertex = (-1, 5)
This means,
The translated graph has been shifted 5 units up.
So,
f(x) = (x - 1)² + 5
Thus,
The translated function is
f(x) = (x - 1)² + 5

kim has a scale drawing of a car with a scale of 1 in : 3 ft. what is the scale factor
Final answer:
The scale factor for the scale drawing of a car with a scale of 1 inch : 3 feet is 1:36, or the fraction 1/36.
Explanation:
The student has a scale drawing of a car with a scale of 1 inch : 3 feet. To find the scale factor for this drawing, you need to convert feet into inches since the scale is given in inches to feet. There are 12 inches in a foot, so 3 feet is the same as 36 inches. Therefore, the scale for the car drawing is 1 inch on the drawing for every 36 inches of the actual car.
The scale factor is the ratio of the dimension in the drawing to the actual dimension of the object. In this case, the scale factor is 1:36, which can be written as the fraction 1/36. This means that every inch on the scale drawing represents 36 inches on the actual car.
