5 . x ÷ 7 = 10 or less
5 . 14 = 70 ÷ 7 = 10
The unknown number, when multiplied by five and divided by seven, has to result in a value of 10 or less. To find this number, we solve the inequality 5x / 7 <= 10 and find that x must be less than or equal to 14.
Explanation:The question is asking for a number that, when multiplied by five and then divided by seven, yields a result of 10 or less. Let's denote the unknown number as x. We can put this into a mathematical inequality:
5x / 7 <= 10
To solve for x, we first multiply both sides by 7 to cancel the denominator on the left side:
5x <= 70
Then, we divide both sides by 5 to isolate x:
x <= 14
Therefore, the number must be less than or equal to 14.

The slope of a line is 0. What do you know about the line?
Your answer (C, the line is vertical) is correct
Your line would have to be horizontal. A vertical line yields an undefined slope.
Slope is rise over run. For a horizontal line you would have 0 rise and X amount of run or 0/x. 0 divided by anything = 0
For a vertical line, you would have the opposite, X rise and 0 run or x/0. You cannot divide by 0. It is impossible.
Therefore, your answer is the second option.

Susanna spends a total 0f 47 minutes on her project. How many more minutes than Susanna does Abby spend working? Draw a number line to model the problem, and write an equation to solve.
a - 47 = more time spent
In this mathematical problem, Abby's time is represented as x and the difference in time between Abby's and Susanna's work can be modeled by the equation x-47=y, where y is the extra time Abby spends. A number line can be used to visualize this problem, but without knowing Abby's time, we cannot determine y.
Explanation:The subject of this problem is mathematics and it discusses time spent by two individuals on their project. We know that Susanna spends 47 minutes on her project. However, we do not know how much time Abby spends on her project. We could represent the time Abby spends on her project as x.
To visualize the situation, we can draw a number line. Place a point at 47 which represents Susanna's time. Then place another point at x which represents Abby's time.
The difference in time between Susanna and Abby can be represented by the equation x - 47 = y, where y is the number of extra minutes Abby spends working on her project.
Without any additional information on how much time Abby spent on her work, it's impossible to give a specific answer.

what is the anwser to x-6y=-30
Steps for solving for x.
Step 1. Add 6y to both sides
x = -30 + 6y
Step 2. Regroup terms

The function p(x)=8x-10 shows the profit, in dollars, for selling x books.
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
For the function p(x) = 8x - 10, the profit for selling 20 books is $150.
Explanation:
In the problem, the function p(x) = 8x - 10 represents the profit, in dollars, for selling 'x' books. When it's stated that p(20) = 150, it means that by substituting the value of 'x' as 20 in the function, we get the value as 150. In terms of the problem, it means that the profit for selling 20 books is $150.
Let's break down the problem step by step.
1. You're given the function p(x) = 8x - 10, which represents the profit, in dollars, for selling x books. In this equation, p(x) is the profit, and \(x\) is the number of books sold.
2. You're asked to evaluate the function at x = 20, which means you want to find p(20). To do this, substitute x = 20 into the function and calculate the result.
p(20) = 8(20) - 10
3. Perform the calculation:
p(20) = 160 - 10
4. Complete the subtraction:
p(20) = 150
So, p(20) = 150, which means that the profit for selling 20 books is $150. This is the interpretation of the statement "p(20) = 150" in terms of the problem.

What is the complement of a single die being rolled to a number greater than 2
a single die being rolled to a number less or equal to 2
Final answer:
The complement of rolling a number greater than 2 on a single six-sided die is rolling a 2 or less, which has a probability of 1/3.
Explanation:
In the context of a single six-sided die roll, the complement of rolling a number greater than 2 would be rolling a number that is 2 or less, which in this case includes rolling a 1 or a 2. Each face of a fair six-sided die has an equal chance of landing face up, giving us a probability of 1/6 for landing on a specific number. Since there are two outcomes that are 2 or less (1 and 2), we simply add their probabilities to get the complement. Thus, the complement of rolling a number greater than 2 is:
P(rolling a 1 or 2) = P(rolling a 1) + P(rolling a 2)
= 1/6 + 1/6
= 1/3.
Therefore, there is a 1/3 chance of rolling a number that is 2 or less when rolling a single fair six-sided die.
Two enterprising college students decide to start a business. They will make up and deliver helium balloon bouquets for special occasions. It will cost them $39.99 to buy a machine to fill the balloons with helium. They estimate that it will cost them $2.00 to buy the balloons, helium and ribbons needed to make each balloon bouquet. Which of the following expressions could be used to model the total cost for producing b balloon bouquets?
$2.00b + $39.99$37.99b$39.99b + $2.00$41.99bSave
Answer:
Option A.
Step-by-step explanation:
Machine to fill the balloons with helium will cost = $39.99
Cost of the balloons, helium and ribbons for each bouquet = $2.00
If b balloon bouquets are produced then cost of b balloon bouquets = $2b
Total cost for producing b balloon bouquets = cost of machine + cost of material
= $(39.99 + 2b)
Therefore, cost to produce b bouquets will be $2.00b + $39.99
Hence option A is the answer.

please help.......if Frans fudge recipe calls for 2 1/2 cups of sugar and she increases it by 2/5 of a cup, how much sugar does she use?
Fran's fudge recipe, originally calling for [tex]2\frac{1}{2}[/tex] cups of sugar, would require [tex]2\frac{9}{10}[/tex] cups after she increases the sugar by 2/5 of a cup. The process involves converting mixed numbers to improper fractions, finding a common denominator, and then adding the fractions together.
If Fran's fudge recipe calls for [tex]2\frac{1}{2}[/tex] cups of sugar and she increases it by 2/5 of a cup, we first need to find the common denominator to combine these two fractions. To do this, we express [tex]2\frac{1}{2}[/tex] cups as an improper fraction, which is 5/2 cups (since [tex]2\frac{1}{2}[/tex] = 5/2). Then, we add 2/5 of a cup to it.
Steps:
Convert 2 1/2 cups to an improper fraction: [tex]2\frac{1}{2}[/tex] = 5/2.
Add 2/5 cup to 5/2 cups: To add these, we need a common denominator, which is 10. So, we convert 5/2 to 25/10 and 2/5 to 4/10.
Add the two fractions: (25/10) + (4/10) = (29/10).
Convert 29/10 back to a mixed number: 29/10 = [tex]2\frac{9}{10}[/tex].
Therefore, Fran uses [tex]2\frac{9}{10}[/tex] cups of sugar in her fudge recipe after the increase.

A random sample produced the pie chart below. The chart gives percentages of students that under reported, accurately reported, and over reported their heights. If there are 2,500 students at the school, how many of them can you reasonably expect report their height accurately?
A. 500
B. 200
C. 50
D. 20
Answer:
The correct option is A.
Step-by-step explanation:
Total number of students at the school is 2,500.
In the given pi chart Pink, Yellow and Sky Blue color represent the percentage of students that under reported, accurately reported, and over reported their heights respectively.
From the graph we can conclude that the yellow portion is approximately one fifth of whole circle. It means the number of students that accurately reported their height is one fifth of total number of students.
[tex]2500\times \frac{1}{5}=500[/tex]
Therefore the number of students that accurately reported their height is 500. Option A is correct.
Answer:
Option A) 500
Step-by-step explanation:
We are given the following information:
Total number of students = 2500
From pie chart:
[tex]\text{Under Reported }= \displaystyle\frac{1}{5}\times 100\% = 20\%\\\text{Accurately Reported }= \displaystyle\frac{1}{5}\times 100\% = 20\%\\\text{Over Reported }= \displaystyle\frac{3}{5}\times 100\% = 60\%[/tex]
We have to find the number of students whose height were accurately reported =
[tex]\text{Number of students whose height were accurately reported }= \\\text{Number of students}\times \text{Percentage of students whose height were accurately reported}\\= 2500\times 20\%\\\\= 2500\times \displaystyle\frac{20}{100} = 2500\times \frac{20}{100} = 500[/tex]
500 students report their height accurately.

Answer:
[tex]x^3\cdot x^2=x^5[/tex]
Step-by-step explanation:
The rule to multiply two powers with the same base consists in adding the exponents. The general form would be:
[tex]x^a\cdot x^b=x^{a+b}[/tex]
For verifying the previous rule, let's say that x=2, a=2 and b=3. The equation would be:
[tex]2^2\cdot 2^3=2^{5}[/tex]
[tex](4)\cdot (8)=2^{5}[/tex]
[tex]32=32[/tex]
We have obtained the result multiplying individually and applying the rule.
Now, for the [tex]x^3\cdot x^2[/tex] exercise, the result would be obtained by adding 3 and 2. It would be:
[tex]x^3\cdot x^2=x^{3+2}=x^5[/tex]

Edison has a sales job and receives $45,448 as his annual pay plus commission his company pays him commission of 15% on this total sales if he makes sales of $25000 in the first 3 months how much will he be paid for those 3 months
Answer:
Edison will be paid $15,112 for the first three months.
Step-by-step explanation:
We know that Edison receives an annual fixed pay of $45,448. Therefore, his fixed pay for each month will be [tex]\frac{45448}{12}=\$3787.33[/tex]
Therefore, his fixed pay for the 3 months will be [tex]3787.33*3=\$11362[/tex].
Now let us compute the commission that Edison received. For that we will compute the 15% of the total sales for those 3 months. Total sales for the 3 months is $25000. Therefore, his commission would be [tex]0.15*25000=\$3750[/tex]
Therefore, total pay that Edison received during first 3 months would be:
[tex]11362+3750=\$15,112[/tex]
Edison will be paid $48,862 for the first 3 months.
To calculate Edison's total payment for the first 3 months, we need to consider both his annual pay and the commission he earns from his sales.
First, let's calculate the commission Edison earns from his sales. He makes sales of $250,000 in the first 3 months, and the commission rate is 15% of the total sales. The commission can be calculated as:
[tex]\[ \text{Commission} = \text{Total Sales} \times \text{Commission Rate} \] \[ \text{Commission} = \$250,000 \times 0.15 \] \[ \text{Commission} = \$37,500 \][/tex]
Next, we need to calculate Edison's base salary for 3 months. Since his annual pay is $45,448, we divide this by 4 to get the quarterly pay (as there are 4 quarters in a year):
[tex]\[ \text{Quarterly Pay} = \frac{\text{Annual Pay}}{4} \] \[ \text{Quarterly Pay} = \frac{\$45,448}{4} \] \[ \text{Quarterly Pay} = \$11,362 \][/tex]
Now, we add the quarterly pay to the commission to find the total payment for the first 3 months:
[tex]\[ \text{Total Payment for 3 Months} = \text{Quarterly Pay} + \text{Commission} \] \[ \text{Total Payment for 3 Months} = \$11,362 + \$37,500 \] \[ \text{Total Payment for 3 Months} = \$48,862 \][/tex]
A first number plus twice a second number is 1. Twice the first number plus the second totals 14. Find the numbers
Let's consider the first number to be [tex]f[/tex] and the second number to be [tex]s[/tex]. Based on the information in the problem, we can create the following equations:
[tex]f + 2s = 1[/tex]
[tex]2f + s = 14[/tex]
Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:
[tex]2f + 4s = 2/tex]
[tex]2f + s = 14[/tex]
Now, subtract [tex]2f[/tex] from both equations to get:
[tex]3s = -12[/tex]
[tex]s = -4[/tex]
Now that we have found [tex]s[/tex], "plug" it back into an equation to find [tex]f[/tex]:
[tex]f + 2(-4) = 1[/tex]
[tex]f - 8 = 1[/tex]
[tex]f = 9[/tex]
Our answers are s = -4 and f = 9.
Hey there!!
Let's take the first number as ' x '
Let's take the second number as ' y '
First number + twice the second number is 1
x + 2y = 1 ------------ ( 1 )
Twice the second number + second number is 14.
2x + y = 14 ----------- ( 2 )
Now let's get them all together...
...................................................................................................................................................................
x + 2y = 1 --- ( 1 )
2x + y = 14 --- ( 2 )
Now, let's multiply the first equation with 2 ...
...................................................................................................................................................................
2x + 4y = 2 --- ( 1 )
2x + y = 14 --- ( 2 )
Now, let's subtract the second equation from the second...
...................................................................................................................................................................
2x + 4y = 2 --- ( 1 )
- ( 2x + y ) = - ( 14 )
...................................................................................................................................................................
2x + 4y = 2 --- ( 1 )
-2x - y = -14 --- ( 2 )
...................................................................................................................................................................
3y = -12
Divide by 3 on both sides...
y = -4
The second number is -4.
We have the first equation x + 2y = 1
We got the y value, now substitute the value of y to get the value of x
...................................................................................................................................................................
x + 2y = 1
x + 2 ( -4 ) = 1
x - 8 = 1
Add 8 on both sides
x = 9
Hence, the second number is 9.
