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.

Answer:

1, 2, 3, 6

Step-by-step explanation:

The given equation is,

[tex]\Rightarrow ax = 6[/tex]

[tex]\Rightarrow x = \dfrac{6}{a}[/tex]

We need to to find all the whole values of a for which the solution of the equation i.e x will be a whole number.

We know that when a number is divided by one of its factor it leaves a remainder of 0 or the result we get is a whole number.

That is why, we need a as one of the factors of 6, i.e 1, 2, 3, 6 in order to get x as a whole number.

Answer:

x=2

y=-5

Step-by-step explanation:

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

-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 cosine of an angle is the ratio of the adjacent side(to that angle) to the hypotenuse of the right triangle.

Suppose the ladder makes [tex]\theta[/tex] from the ground.

So, [tex]Cos\theta = \frac{4}{20}[/tex]

[tex]Cos\theta = \frac{1}{5}[/tex]

[tex]\theta =Cos^{-1} (\frac{1}{5} )[/tex]

[tex]\theta =Cos^{-1} 0.2[/tex]

[tex]\theta=1.37[/tex]°

Thus, the ladder makes 1.37° with the ground.

The ladder makes an angle of approximately 76.31 degrees with the ground.

Given:

- The length of the ladder (hypotenuse) is 20 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:

[tex]\[ h^2 + 4^2 = 20^2 \] \[ h^2 = 20^2 - 4^2 \] \[ h^2 = 400 - 16 \] \[ h^2 = 384 \] \[ h = \sqrt{384} \] \[ h = 19.6 \text{ feet (approximately)} \][/tex]

Now we can find the angle [tex]\(\theta\)[/tex]:

[tex]\[ \tan(\theta) = \frac{h}{4} \] \[ \tan(\theta) = \frac{19.6}{4} \] \[ \tan(\theta) = 4.9 \][/tex]

To find the angle [tex]\(\theta\)[/tex], we take the arctangent (inverse tangent) of 4.9:

[tex]\[ \theta = \arctan(4.9) \] \[ \theta \approx 76.31^\circ \][/tex]

Therefore, the ladder makes an angle of approximately 76.31 degrees with the ground.

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.

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.

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:

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

[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

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

    = 658.24 m

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.

Answer: 4 flour + 3 sugar = 44lbs

6 flour = 48lbs

We can divide 48lbs by 6 bags of flour to get 8lbs per bag of flour.

4 bags of flour multiplied by 8lbs is 32lbs. 44lbs - 32lbs = 12lbs

12lbs divided by 3 bags of sugar = 4lbs per bag of sugar.

The ratio is flour to sugar: 8:4 or 2:1

We create two equations based on the information given: 4F+3S=44 and 6F=48. By solving these equations, we find the weight of a bag of flour is 8 pounds and the weight of a bag of sugar is 4 pounds. Thus, the ratio of weight is 2:1.

We can solve this problem by setting up two equations based on the information given and then solve the equations to find the weights of the bags of flour and sugar. Let's denote the weight of a bag of flour as F and the weight of a bag of sugar as S.

From the second equation, we can find that F = 48 / 6 = 8 pounds. Substitute F = 8 into the first equation, we find S = 4 pounds.

Therefore, the ratio of the weight of a bag of flour to a bag of sugar is 8:4 or simplified to 2:1 (option a).

Answer:

x=15/a+b/a

Step-by-step explanation:

a*x=15+b

you need to move all the variables (a) to one side and to do that you can re-organize it to say

x*a=15+b

to get the answer you need to divide (a) and that gets you your answer,

x=15/a+b/a

Here is your equation:

[tex]ax=15+b[/tex]

You're trying to find x alone. To find a specific variable, you have to do the opposite of what's happening to the variable, which is x in this equation.

In this equation, x is being multiplied by a. That means you have to do the opposite of multiplying, which is dividing by a. To leave x alone, divide both sides by a.

[tex]ax \div a = \frac{15+b}{a}[/tex]

Now that you have divided both sides by a, which leaves x alone, you have:

[tex]x = \frac{15+b}{a}[/tex]

Your answer is [tex]x = \frac{15+b}{a}[/tex]
