Answer:

The correct option is;

A total of forty hours a week

Step-by-step explanation:

The given information in the question are;

The number of hours of sleep Nina gets during weeknights = five hours

The number of hours of sleep Nina gets per night on weekends = ten hours

The number of days in a week = 5 days

The number of days in a weekend = 2 days

Therefore;

The number of hours of sleep Nina gets per week = 5 days × 5 hours/day + 2 days × 10 hours/day

∴ The number of hours of sleep Nina gets per week = 25 hours + 20 hours = 45 hours

The number of hours of sleep Nina gets per week = 45 hours

To better concentrate on schoolwork, Nina could get a total of forty hours a week of sleep a week to increase the number of hours she spends weekly on her schoolwork by up to 5 hours (45 hours - 40 hours).

Answer:

3d(5-4cd)

Step-by-step explanation:

15d - 12cd²  (we see that the highest common factor of 15 and 12 is 3, hence we can factor 3 out)

= 3 (5d - 4cd²)      (we also notice that d appears in both terms in the parantheses. hence we can also factor d out)

= 3d(5-4cd)

Let's use an equation to solve this problem.

[tex]y=24x+16[/tex]

Where x is the price of each cupcake, y is the total cost, 16 is the price of the layer cake, and 24 is the number of cupcakes.

[tex]57=24x+16[/tex]

[tex]41=24x[/tex]

[tex]x=\frac{41}{24}[/tex]

Which simplifies around to $1.71 dollars.

Hope this helps.

Answer:

4 batches

Step-by-step explanation:

First, you need to convert the mix number into a single fraction:

3 1/5 = 16/5 total barrels of coffee beans used

This allows us to divide the numbers easier in the next step.

Next, because each batch uses 4/5 of a barrel of beans, you need to divide 16/5 by 4/5:

(16/5) / (4/5) = 16/4 = 4 batches

(The fives cancel out because they are the same divisor.)

I hope this helps!

Answer:

x = 22

Step-by-step explanation:

158 + x + 148 + 32 must sum up to 360 as this is a quadrilateral.  Thus:

x + 338 = 360.

Subtracting 338 from both sides, we get x = 22

Answer:

9>a

Step-by-step explanation:

The greater than symbol is >

The less than symbol is <

It can be helpful to imagine the signs as little crocodile mouths. They will turn their heads to the biggest catch, or in this case, the greater number. So the open end of the sign will be towards the greater number.

Answer:

9>a

Step-by-step explanation:

the side with the bigger opening means that side of the inequality has a greater value  so since 9 is greater than a the bigger opening will go to 9.

Answer:

6/25

Step-by-step explanation:

6/25

0.24... as a fraction in simplest form is 6/25.

A fraction is in its simplest form if the numerator and denominator have no common factors other than 1.

In other words, you cannot divide the top and bottom any further and have them still be whole numbers. The simplest form is also called lowest terms.

We have:

0.24 = 24/100

In this case, 24 and 100 have a common factor, which is 4. Thus, 0.24 (24/100) in simplest form will be:

0.24 = 24/100 = 6/25  (divide both numerator and denominator by 4)

Hello, I do not see a question nor a histogram for the statement/info provided. I am assuming that the question that you are referring to is "Which of these most likely describes the data shown in the histogram?"

Answer:

The correct answer would be: A, The cards are grouped into five intervals according to price. The prices of the cards  vary within each interval, and the highest frequency is 21.

Explanation:

From the histogram (below), you can observe that the highest frequency for the diagram is in fact 21, so you can eliminate answer options B and D.

You are left with either A or C, but you can tell that C is wrong as it states "The prices of the cards are  limited to a few whole number values", but in truth the histogram displays values that are decimals, the prices of the cards  vary within each interval.

Hope this helps!

A constant function is a function having the same value of range for different values of the domain.

The interval on which the given function is constant is x ∈ [ -2, 2 ].

A constant function is a function having the same value of range for different values of the domain.

We have,

The graph shows that the function is constant at an interval.

The graph of a constant function is always a straight line.

We see that we have a short straight line on the graph.

The straight line starts from the x = -2 till x = 2 on the x-axis.

The straight line has the constant y = -2 on the y-axis.

The x values are called the domain.

The y value is called the range.

The interval on which the graph is constant is x ∈ [ -2, 2 ].

Thus, the interval on which the given function is constant is x ∈ [ -2, 2 ].

Answer:

x = [tex]\frac{1}{4}[/tex] ± [tex]\frac{1}{2}[/tex][tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] (4x - 1)² = 4 ( multiply both sides by 2 to clear the fraction )

(4x - 1)² = 8 ( take the square root of both sides )

4x - 1 = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ( add 1 to both sides )

4x = 1 ± 2[tex]\sqrt{2}[/tex] ( divide both sides by 4 )

x = [tex]\frac{1+/-2\sqrt{2} }{4}[/tex]

   = [tex]\frac{1}{4}[/tex] ± [tex]\frac{1}{2}[/tex][tex]\sqrt{2}[/tex]

Answer:

f(–6) = 10

Step-by-step explanation:

EDGE

f(-6)=10 is the true option regarding the function.

The function is a relationship between a set of inputs with a set of outputs such that one input cannot have two outputs.

General form of a function is f(x)=y

The ordered pairs (x,y) or (x,f(x)) represent the graphical points of a function in the coordinate plane.

The given function is given by the set of ordered pairs

(x,y)={(8,-3),(0,4),(1,-5),(2,-1),(-6,10)}

Clearly f(-6)=10 is the only correct option.

Answer:

150 vouchers to wash trucks were sold

250 vouchers to wash compact cars were sold

Step-by-step explanation:

Here, we are interested in calculating the number of each type of vouchers sold.

Let the number of vouchers to wash trucks be x while the number of vouchers to wash compact trucks be y.

Firstly, we know that both sums up to be 400.

Mathematically;

x + y = 400 •••••••••(i)

Secondly,

since a voucher to wash trucks sell $4, and we sold a total of x, the amount generated from selling is 4 * x = $4x

Same way for the vouchers to wash compact cars, we have a total of $3 * y = $3y

The sum of both gives $1350, which is the total sales.

Mathematically;

4x + 3y = 1350 ••••••(ii)

So we have two equations to solve simultaneously;

x + y = 400

4x + 3y = 1350

Multiply equation i by 4 , we have;

4x + 4y = 1600

4x + 3y = 1350

Subtract equation ii from i, we have 4y-3y = 1600-1350

y = 250

From equation 1, we know that

x + y = 400

This means that;

x = 400 -y

x = 400 -250

x = 150

Responder:

94,800 pesos

Explicación paso a paso:

Dado que:

Para vender x de un producto diariamente, el precio al que debe vender cada uno de sus productos = 96800 - 10x pesos

Por lo tanto, para vender 200 unidades al día, el precio a cobrar será:

Sustituye 200 en lugar de x en la ecuación de precio anterior,

Es decir ;

x = 200

Precio = 96,800 - 10 (200) pesos

Precio = 96,800 - 2000

Precio = 94,800 pesos

De ahí que el precio a cobrar al vender 200 unidades diarias sea de 94.800 pesos.
