Your weekly base salary is $150. You earn $20 for each cell phone that you sell. What is the minimum amount you can earn in a week?

Answer:

Step-by-step explanation:

Put the values of P and Q to the equation Px - 45 = Qx + 75:

15x - 45 = 15x + 75     subtract 15x from both sides

-45 = 75   FALSE

In other cases, we get some value x.

Example:

A. P = -45 and Q = -75

-45x - 45 = -75x + 75     add 45 to both sides

-45x = -75x + 120      add 75x to both sides

25x = 120       divide both sides by 25

x = 4.8

Each "x" represents one tree that produced that amount of sap in gallons.

To find the total amount of sap produced, add all of the amount of sap produced from each tree

3 trees produced 1/4 gallons of sap

2 trees produced 3/8 gallons of sap

4 trees produced 5/8 gallons of sap

1 tree produced 1 gallon of sap

You can do this:

[tex]\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{3}{8}+\frac{3}{8} +\frac{5}{8}+\frac{5}{8}+\frac{5}{8}+\frac{5}{8}+1[/tex]

[tex]=\frac{3}{4}+\frac{6}{8}+\frac{20}{8}+1[/tex]      

[tex]\frac{3}{4}+\frac{26}{8}+1[/tex] Make all the denominators the same

[tex]\frac{6}{8}+\frac{26}{8}+\frac{8}{8}=\frac{40}{8}=5[/tex]

5 gallons

Or you could have done:

[tex](\frac{1}{4} *3)+(\frac{3}{8}*2)+(\frac{5}{8}*4)+(1*1)[/tex]

[tex]=\frac{3}{4}+\frac{6}{8}+\frac{20}{8}+1[/tex]      

[tex]\frac{3}{4}+\frac{26}{8}+1[/tex] Make all the denominators the same

[tex]\frac{6}{8}+\frac{26}{8}+\frac{8}{8}=\frac{40}{8}=5[/tex]

5 gallons

Answer:

5 gallons

Step-by-step explanation:

because if u add all togather u get 6/8+26/8+8/8+40/8= It would be 5 Gallons

Answer:

F = 2

Step-by-step explanation: If you want to know which one is a solution, you have to substitute the numbers in for F.

F = 7:

3 > f

3 > 7

This is false because 3 is NOT greater than 7, it is less than 7.

F = 9:

3 > f

3 > 9

This is false because 3 is NOT greater than 9, it is less than 9.

F = 2:

3 > f

3 > 2

This is TRUE because 3 IS greater than 2.

Roger saves 4 Dollars!

Roger earns $24 weekly and spends 1/6 on lunch and 2/3 on music. Calculating these expenses, he spends $4 on lunch and $16 on music, totaling $20. Roger saves the remaining $4.

To find out how much Roger saves, we need to calculate these expenses and subtract them from his total earnings.

Adding the amounts spent on lunch and music: $4 + $16 = $20.

subtract the total expenses from his total earnings: $24 - $20 = $4.

Therefore, Roger saves $4 after his expenses on lunch and music.

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0 or (0,y))

Since you know m = 2/3, plug it into the equation

y = 2/3x + b

To find "b", plug in the point into the equation (-3,2)

y = 2/3x + b

2 = 2/3(-3) + b

2 = -2 + b

4 = b

y = 2/3x + 4

Point-slope form:

y - y₁ = m(x - x₁)        

You know:

m = 2/3

(x₁ , y₁) = (-3,2)

Plug this into the equation:

y - y₁ = m(x - x₁)  

y - 2 = 2/3(x - (-3))

y - 2 = 2/3(x + 3)

Final answer:

To find the approximate solution to the system of linear equations, set the equations equal to each other, combine like terms, simplify, solve for x, substitute the value of x back into either equation to find y, and simplify further. The approximate solution is x = 3/2 and y = -1/8.

Explanation:

Given the system of linear equations:

y = -7/4 x + 5/2

y = 3/4 x - 3

Set the two equations equal to each other:

-7/4 x + 5/2 = 3/4 x - 3

Combine like terms:

2x + 5 - 14 = 6 - 12

Simplify:

2x - 9 = -6

Add 9 to both sides:

2x = 3

Divide both sides by 2:

x = 3/2

Substitute the value of x back into either equation to find the value of y:

y = -7/4 * (3/2) + 5/2

Simplify:

y = -21/8 + 20/8

Add the fractions:

y = -1/8

Therefore, the approximate solution to the system of linear equations is x = 3/2 and y = -1/8.

Answer:

658.24 m

Step-by-step explanation:

The figure makes a triangle with vertices abc.

Where ab = 500 m

           bc = 350 m

The angle abc = 100°

Using the cosine rule we can find the distance ac.

ac² = 500²+350² - 2×500×350×cos100°

      = 372,500 - -60,776.86

      = 433,276.86

ac = √433,276.86

[tex]y = -\frac{1}{4}x +4\ /\cdot4\\4y=-x+16\\x+4y=16\\C[/tex]

Answer:

C) x + 4y = 16

Step-by-step explanation:

The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.

As we need all the coefficients to be integers, we have to multiply by 4 on both sides of the equation (that will make the coefficient of x integer). We have to multiply it on both sides because is an equation.

4*y = 4*(-1/4x + 4)

4y = -x + 16

Now we need the x-term to be on the left side of the equation, so we add x on both sides:

x + 4y = -x + 16 + x

x + 4y = 16

You can add two square roots of the numbers if the numbers are the same:

[tex]\sqrt{a}+\sqrt{a}=2\sqrt{a}\\\\n\sqrt{a}+m\sqrt{a}=(n+m)\sqrt{a}\\\\\sqrt{a}+\sqrt{b}=\sqrt{a}+\sqrt{b}[/tex]

Final answer:

To find the sum of square roots, you can add the square roots together if the numbers underneath are the same. If the numbers are different, you cannot simplify them further.

Explanation:

To find the sum of a square root, you need to add the square roots together. However, the numbers under the square roots must be the same. For example, if you have √2 + √2, you can add them to get 2√2. But if you have √2 + √3, you cannot simplify it any further.

Another way to find the sum of square roots is to simplify them using the multiplication property. For example, if you have √2 + 2√2, you can combine them as (1+2)√2 = 3√2.

It is important to note that you can only add square roots with the same number underneath. If the numbers are different, you cannot simplify them further.

Final answer:

The soccer player will run 23.04 miles in 9 days.

Explanation:

To find out how many miles the soccer player will run in 9 days, we need to calculate the average number of miles he runs per day. We can do this by dividing the total distance he ran by the number of days.

So, 180.48 miles ÷ 70.5 days = 2.56 miles per day.

Now we can determine how many miles he will run in 9 days by multiplying the average number of miles per day by 9.

So, 2.56 miles per day × 9 days = 23.04 miles.

-12y-66-y=-1

-13y-66=-1

-13y=65

y=-5

x=4(-5)+22

x=-20+22

x=2

Answer:

y = 5

x = 2

Step-by-step explanation:

So we know what x is already.

x = 4y + 22

Now we plug that in to the first equation.

-3 ( 4y + 22) - y = -1

Distribute the -3.

-12y - 66 - y = -1

Combined like terms:

-13y - 66 = -1

-13y = 65

Divide -13 on both sides:

y = -5

Now plug your y into the second equation:

x = 4(-5) + 22

x = -20 + 22

Simplify:

x = 2

Check your answer:

-6 - (-5) = -1

2 = -20 + 22

The ladder with a length of 20 feet makes 1.37° with the ground.

Length of the ladder = 20 feet

Distance of base of the ladder from the wall = 4 feet

- The distance from the wall (adjacent side) is 4 feet.

Using the tangent function, we have:

[tex]\[ \tan(\theta) = \frac{\text{opposite side}}{\text{adjacent side}} \][/tex]

 Let h be the height the ladder reaches on the wall. Then:

Answer:

The amount you would earn is $64.80

Step-by-step explanation:

We know to start that you get 45% of the cost per customer. That's because the customer gives you 20% and you boss gives you 25% (1/4). To find how much that is, multiply it by the cost.

$18 * 45% = $8.10

Now knowing this, we can multiply that amount by the 8 customers per day.

$8.10*8 = $64.80

On a typical day, I can expect to earn $64.80 for myself.

To calculate my earnings for the day, we'll break it down step by step:

Shampoo, cut, and style cost: Each job's cost is $18.00.

Tips: I generally receive a 20% tip from each customer. To calculate the total tip earnings for the day, we multiply the job cost by 0.20 (20%):

Total tips = 8 customers * ($18.00 * 0.20) = 8 * $3.60 = $28.80

Salon owner's payment: The salon owner pays me ¼ of each job's cost. To calculate the total payment from the salon owner for the day, we multiply the job cost by 0.25 (1/4):

Total owner's payment = 8 customers * ($18.00 * 0.25) = 8 * $4.50 = $36.00

My earnings: Finally, to calculate my total earnings for the day, we sum up the tips and the salon owner's payment:

Total earnings = Total tips + Total owner's payment = $28.80 + $36.00 = $64.80

The two whole numbers are 10 and 11.

Answer:

$2.45        

Step-by-step explanation:    

Let x be the number of months.  

We have been given that price of a mango at a fruit stand goes up 5 cents each month. This means that price of mango in dollars after x months will be 0.05x (1 dollar=100 cents).

The first month the stand was open, a mango cost $1.25. This means that cost of mango in the x months after 1st month will be: [tex]1.25+0.05x[/tex]

Now let find the cost of mango in the 25 month by substituting x=24 in our expression because price will increase 24 times after 1st month.

[tex]\text{The cost of a mango be in the 25th month}=1.25+0.05*24[/tex]

[tex]\text{The cost of a mango be in the 25th month}=1.25+1.2[/tex]

[tex]\text{The cost of a mango be in the 25th month}=2.45[/tex]

Therefore, the cost of a mango in the 25th month will be $2.45.

Final answer:

To calculate the cost of a mango in the 25th month, you multiply the 24 intervening months by the $0.05 monthly price increase, which equals $1.20, and add it to the initial cost of $1.25, resulting in a total cost of $2.45.

Explanation:

You want to calculate the cost of a mango in the 25th month if the price increases by 5 cents each month from the initial price of $1.25. To find the cost on the 25th month, we will first find out the total increase in cost after 24 months (since the first month is already at $1.25, we only calculate the increase for the following 24 months). The calculation is 24 months × $0.05 increase per month.

The total increase is:

24 × $0.05 = $1.20.

Add this increase to the initial cost to find the cost on the 25th month:

$1.25 + $1.20 = $2.45.

Therefore, the cost of a mango in the 25th month will be $2.45.
