Carlos has saved 19.80. Shaq saved 5/6 of the amount that Carlos saved. Deontae
saved 4 times as much as Shaq. What is the total saved amount of all three

Answer:

217

Step-by-step explanation:

124%=x

36%=63

=>[tex]x=\dfrac{63\times 124}{36}=217[/tex]

Final answer:

To find 124% of the original number, we first determine that the number is 175 by dividing 63 by 0.36 (the equivalent of 36%). We then multiply 175 by 1.24 to arrive at 217, which is 124% of the original number.

Explanation:

To solve the student's question, we'll need to find the original number that 36% represents, and then calculate 124% of that number. If 36% of a number is 63, we would set up an equation to find 100% of that number (the whole number).

Let's call the unknown number 'x'. The equation would be 0.36x = 63. To solve for 'x', we would divide both sides of the equation by 0.36:

x = 63 ÷ 0.36

Once we've found the value for 'x', we then find 124% of that number by multiplying 'x' by 1.24 (since percent means 'per hundred' and 124% is equivalent to 1.24 when expressed as a decimal).

Now, calculating the values:

x = 63 ÷ 0.36 = 175

To find 124% of 175, we do the following calculation:

1.24 × 175 = 217

Therefore, 124% of the number is 217.

Step-by-step explanation:

You treat inequality questions just like normal equation with an equal sign. You only have to worry about the inequality when you do the shading part.

Your first goal is to solve for y, which I did at the top.

And remember that when you divide/multiply by a negative number you have to flip the inequality sign.

So the first equation is already in term of y. (y < 2x + 4)

So you only have to solve for y for -3x - 2y ≥ 6.

I solved that and got y ≤ -3/2x - 3.

Now you have 2 equations. y < 2x + 4 and y ≤ -3/2x - 3

First you gotta treat it like a normal equation and graph them.

So i graphed y = 2x + 4 and y = -3/2x - 3. I assume you already know how do do that.

btw. < and > have dotted lines, while ≤ and ≥ have solid lines.

Now for the shading, you gotta look at the inequality sign.

y < 2x + 4 has a less than sign, so you have to shade everything underneath the line you graphed.

y ≤ -3/2x - 3 is also less than, so you have to shade everything underneath that line as well.

So in the future, you you get a > or ≥ then you have to shade above the graph.

Let x = the number of songs you can buy.

If you use company A at 0.79 dollars per song, your variable is 0.79x. If you use company B at 0.99 dollars per song, your variable is 0.99x. You are going to set both equal to 30.

Company A: 0.79x = 30

Company B: 0.99x = 30

When solving (though I know you didn't ask), do note that you cannot buy part of a song so you would need to round down to the nearest whole number.

So if you use company A, you divide both sides by 0.79 to isolate the variable x and satisfy the division principle of equality:

x = 30/0.79.

Simplify and your answer is 37.97, round down to 37 songs; you'd have 37 songs with company A and 77 cents left over in your account just sitting there because what really can you do with 77 cents on the App Store?

To model the song downloading situation with a budget of $30, we use the equations 0.79x <= 30 for Company A and 0.99x <= 30 for Company B, where x is the number of songs.

To model the situation where a student has $30 to spend on downloading songs, we can write two separate linear equations, one for each company. For Company A, which charges $0.79 per song, the equation will be:

0.79x ≤ 30

Where x represents the number of songs the student can download from Company A. For Company B, which charges $0.99 per song, the equation will be:

0.99x ≤ 30

Again, x represents the number of songs the student can download from Company B, but the cost per song is different, hence a different equation.

These equations are used to determine the maximum number of songs the student can download from each company without exceeding the $30 budget.

Answer:

w = 1.25[tex]\times[/tex] t

The constant 1.25 denotes the rate of water flowing in the tub per minute.

Step-by-step explanation:

Water is running into a bathtub at a constant rate.

In 2 minutes , 2.5 gallons of water is filled in the tub. We are supposed to find the relation between the amount of water and the time taken and we also have to find the definition of the constant of proportionality.

Let w be the amount of water and t be the time taken in minutes.

The rate at which water is filled in the tub = [tex]\frac{2.5}{2}[/tex]

                                                                      = 1.25 gallons/minute

The water filled , w = 1.25[tex]\times[/tex] t

The constant 1.25 denotes the rate of water flowing in the tub per minute.

Final answer:

The question asks for two equations representing the proportional relationship between water in a bathtub (w) and time (t), given a constant fill rate. We derived that water fills the tub at a rate of 1.25 gallons per minute, leading to two equations: w = 1.25t and t = w / 1.25, explaining both the fill rate and how to calculate time based on a certain water amount.

Explanation:

The question involves finding two equations for a proportional relationship between the amount of water (w, in gallons) in a bathtub and the time (t, in minutes) it takes for the water to fill up at a constant rate, given that 2.5 gallons of water fill the tub in 2 minutes. To build these equations, we will use the information provided to determine the constant of proportionality (k), which represents the rate at which the tub fills.

First, we find the constant of proportionality (k) by dividing the amount of water by the time:

k = w / t = 2.5 gallons / 2 minutes = 1.25 gallons per minute

This gives us two equations based on this scenario:

w = 1.25t (Equation 1)

t = w / 1.25 (Equation 2)

Equation 1 tells us the amount of water (w) in the bathtub after t minutes, showing that the bathtub fills at a rate of 1.25 gallons per minute. Equation 2 allows us to find the time (t) it takes to reach a certain amount of water (w) in the bathtub, by dividing the amount of water by the rate of 1.25 gallons per minute.

The constant of proportionality (1.25 gallons per minute) in both equations indicates the rate at which the tub fills with water. It tells us that for every minute that passes, an additional 1.25 gallons of water are added to the tub.

420cal = 2 cups

Step-by-step explanation:

140cal = 2/3 cup

xcal= 2 cups

Divide 2/(2/3) = 3

Multiply both sides by 3 (answer)

140cal= 2/3 cups (3)

420cal = 2 cups

The 2 cups Contain 420 Cal.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

2/3 Cup contain = 140 Cal

So, 1 cup contain = 140 ÷ ( 2/3)

                             = 140 x 3/2

                             = 70 x 3

                             = 210

Then, In 2 cups = 210 x 2

                          = 420 Cal

Hence, 2 cups Contain 420 Cal.

y = -2x - 3

Step-by-step explanation:

The line has a slope of -2

The line passes through point (-1, -1)

Lets take another point (x, y) on the line,

Slope = change in y ÷ change in x

i.e slope = [tex]\frac{y - -1}{x - -1}[/tex] = -2

[tex]\frac{y + 1}{x + 1}[/tex] = -2

y + 1 = -2x - 2

So let us first solve for brackets in given equation

5x - 15 + 6 = 5x - 9

5x - 9 = 5x - 9

0 = 0

Since the statement is true, there are infinitely many solutions

There are 21 nickels in carol bank

Solution:

Given that Carol's piggy bank consists of quarters and nickels

There are $ 4.55 in total

Let "a" be the number of nickels in bank

Let "b" be the number of quarters in bank

We know that,

1 quarter = $ 0.25

1 nickel = $ 0.05

Given that there are seven more nickels than quarters

Number of nickels = number of quarters + 7

a = b + 7 ---- eqn 1

From given question,

number of nickels in bank x value of 1 nickel + number of quarters in bank x value of 1 quarter = $ 4.55

[tex]a \times 0.05 + b \times 0.25 = 4.55\\\\(b + 7) \times 0.05 + b \times 0.25 = 4.55\\\\0.05b + 0.35 + 0.25b = 4.55\\\\0.3b = 4.55 - 0.35\\\\0.3b = 4.2\\\\b = 14[/tex]

Therefore from eqn 1

a = b + 7 = 14 + 7 = 21

a = 21

Thus there are 21 nickels in carol bank

Answer:

$25.5 per hour.

Step-by-step explanation:

The function C(x) = 25.50x + 50 ........ (1)  models the total cost for a cleaning company to clean a house, where x is the number of hours it takes to clean the house.

Now, from the linear equation it is clear that the change in cost of cleaning from 3 hours and 9 hours are respectively  {From equation (1)}

C(3) = 25.5 × 3 + 50 = $126.5 and

C(9) = 25.5 × 9 + 50 = $279.5

Therefore, the average rate of change of the function between 3 hours and 9 hours will be = [tex]\frac{\textrm {Change in price of cleaning}}{\textrm {Change in hours}}[/tex]

Answer:

Step-by-step explanation:

The length of one edge of a cube with a volume of 1331 cm³ is 11 cm, derived by taking the cube root of the volume.

To calculate the length of one edge of a cube when the volume is given, we use the formula for the volume of a cube: Volume = side³, where 'side' is the length of one edge of the cube.

The cube in question has a volume of 1331 cm³. To find the length of one edge of the cube, we need to take the cube root of the volume. The cube root of 1331 cm³ is 11 cm, meaning each side of the cube measures 11 cm.

The cube root is calculated because raising a number to the third power cubes it, and taking the cube root is the inverse operation. This process allows us to determine the original value that was cubed to get the volume.

Weight of wire of 8.7 meters is 24.36 ounces

Solution:

Given that cable repair person has 8.7 meters of wire

Each meter of the wire weighs 2.8 ounces

To find: Weight of wire

From given information,

weight of 1 meter of wire = 2.8 ounces

Therefore weight of 8.7 meters of wire is found by multiplying weight of 1 meter of wire by 8.7

weight of 8.7 meter of wire = weight of 1 meter of wire x 8.7

weight of 8.7 meter of wire = 2.8 x 8.7 = 24.36

Therefore weight of wire of 8.7 meters is 24.36 ounces

The weight of the 8.7 meters of wire is 24.36 ounces.

To find the weight of the wire, we need to multiply the length of the wire by its weight per unit length. The student has 8.7 meters of wire, and each meter weighs 2.8 ounces.

Multiply the length of the wire in meters (8.7) by the weight per meter in ounces (2.8).

8.7 meters * 2.8 ounces/meter = 24.36 ounces.

Therefore, the total weight of the wire is 24.36 ounces.

Answer:

C) -1/4

Step-by-step explanation:

slope=rise/run

The slope of the line between the points (-4, -3) and (4, 3) is 3/4. Therefore, the correct answer is C.

The slope of a line is the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line. A simple formula to find the slope is:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are any two points on the line.

In this case, we can use the points (-4, -3) and (4, 3) that are given on the graph. Plugging them into the formula, we get:

m = (3 - (-3)) / (4 - (-4))

Simplifying, we get:

m = 6 / 8

The student has to mix 20 jars of $4 nuts with 30 jars of $6 nuts to end up with 50 jars of nuts each worth $4.80.

This question falls under a mathematical concept known as linear equations. Let's denote the number of $4 jars as X and the number of $6 jars as Y. According to the question, X + Y = 50 because the total number of jars is 50. We can also write another equation, which is 4X + 6Y = 50 * 4.8 ($4.80 is the average price of a jar, and there are 50 jars). Solving this system of linear equations gives us X = 20 and Y = 30.
