Answer:

She earned $360 on that paycheck.

Step-by-step explanation:

From the information given, you know that Angela transfers 15% of each paycheck and that she transferred $54 last week. With this, you can say that the amount she earned multiply for 15% is equal to 54, which you can express with the following equation:

0.15x=54, where x is the amount she earned on that paycheck.

Now, you can solve for x:

x=54/0.15

x=360

According to this, the answer is that she earned $360 on that paycheck.

Answer:

x=22

Step-by-step explanation:

(x-2)^1 =5                  Anything to the 1st power is 1 Multiply both sides by 4                                                            

x-2=20                      Move the constant (20) to the right and change its

x=20+2                      sign

x=22

Answer:

the solution is in the figure

the number is -5

Given:

The set of data points on the graph.

To find:

The equation of line that connects the set of data points.

Solution:

From the given graph it is clear that the data points are (20,40), (35,50), (50,60), (65,70).

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Let as consider the line passes through (20,40) and (50,60), then the equation of line is

[tex]y-40=\dfrac{60-40}{50-20}(x-20)[/tex]

[tex]y-40=\dfrac{20}{30}(x-20)[/tex]

[tex]y-40=\dfrac{2}{3}(x-20)[/tex]

Multiply both sides by 3.

[tex]3(y-40)=2(x-20)[/tex]

[tex]3y-120=2x-40[/tex]

Isolate variable terms.

[tex]-2x+3y=120-40[/tex]

[tex]-2x+3y=80[/tex]

Therefore, the standard form of the required line is [tex]-2x+3y=80[/tex].

Answer:

Step-by-step explanation:

-2/6=-1/3

-1/3 is the slope.

formula is rise/run

Step-by-step explanation:

First we find the slope of f(x):

When x increases by 1, f(x) increases by 8. Slope of f(x) = 8/1 = 8.

Slope of g(x) = Coefficient of x = 3.

Therefore the slope of f(x) is greater than the slope of g(x).

When x = 0, f(x) = -1 (given ii the table) Therefore the y-intercept of f(x) is -1.

Y-intercept of g(x) = Constant term = -2.

Since -1 > -2, f(x) have a greater y-intercept.

Answer:

x = 15 ounces

Step-by-step explanation:

A mixture is made with two types of solutions.

Solution A - 45 ounces of 10% saline solution

Solution B - x ounces of 70% saline solution

Resulting mixture - (x + 45) ounces of 25% saline solution

To get the value of x, equation will be,

(45 × 0.10) + (x × 0.70) = (x + 45) × 0.25

4.5 + 0.70x = 0.25x + 11.25

0.25x - 0.70x  = 4.5 - 11.25

-0.45x = -6.75

x = [tex]\frac{6.75}{0.45}[/tex]

x = 15 ounces

Answer:

17/24

Step-by-step explanation:

1. This is an addition problem. Remember, when adding fractions, you first need to find a common denominator.

2. To find the numerator, multiply the current numerators by the number of times the original denominators divide into 24.

3. Now that the denominators are the same, add the numerators and keep the denominator for now.

4. Usually, you would have to reduce the fraction, but since 17/24 is already reduced to its simplest form, 17/24 is your answer.

Answer:

0.84134

Step-by-step explanation:

Given that:

Mean = 3.4 hours

Standard deviation (s) = 2.6 hours

Percentage of students that spend less than 6 hours doing homework

P(x < 6)

Using the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (6 - 3.4) / 2.6

Z = 2.6 / 2.6

Z = 1

p(Z < 1) = 0.84134 ( Z probability calculator)

The percentage of the students at Happy High spends an average of less than 6 hours per week doing homework is 0.84134

Answer:

Scale Factor (Dilation) The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs.

Answer:

The solution is x=-6 and y=7

Step-by-step explanation:

Given equations are:

[tex]4x+4y =4\\3x+4y = 10[/tex]

In elimination method, the co-efficient of one of the variables are equated so that one variable can be eliminated by adding or subtracting the equations

In the given system of equations, the co-efficient of y is already same i.e. 4 so we only have to subtract the equations

Subtracting equation 2 from equation 1

[tex]4x+4y-(3x+4y) = 4-10\\4x+4y-3x-4y = -6\\4x-3x = -6\\x = -6[/tex]

Putting x = -6 in equation 1

[tex]4(-6)+4y = 4\\-24+4y = 4\\4y = 4+24\\4y = 28\\\frac{4y}{4} = \frac{28}{4}\\y = 7[/tex]

Hence

The solution is x=-6 and y=7

Answer:

41.3° and 48.7°

Step-by-step explanation:

Complementary angles are angles with the sum of 90°

if one of the angle is 7.4° less than other

(90 - 7.4) ÷ 2 = 41.3° is the measure of smaller angle and

41.3 + 7.4 = 48.7° is the measure of bigger angle

Answer:

Area of the shaded part is 3.14 square unit.

Step-by-step explanation:

Area of the shaded part = Area of large semicircle - (Area of two small semi circles)

Area of large semicircle with center O = [tex]\frac{1}{2}(\pi r^2)[/tex]

                                                                = [tex]\frac{1}{2}\pi (2)^{2}[/tex]

                                                                = 2π

Area of semicircle with center O' = [tex]\frac{1}{2}\pi (1)^2[/tex]

                                                      = [tex]\frac{\pi }{2}[/tex]

Area of semicircle with center O" = [tex]\frac{\pi }{2}[/tex]

Now substitute these values in the formula,

Area of shaded part = [tex]2\pi - (\frac{\pi }{2}+\frac{\pi }{2})[/tex]

                                  = [tex]\pi[/tex]

                                  = 3.14 square unit

Area of the shaded part is 3.14 square unit.

Answer:

The relationship between the graphs of the two functions is "They are reflections of each other across the y-axis" ⇒ B

Step-by-step explanation:

∵ The points on f(x) are (-2, -31), (-1, 0), (1, 2), (2, 33)

∵ The points on g(x) are (2, 3), (1, 0), (-1, 2), (-2, 33)

∵ All x-coordinates on f(x) multiplied by -1 to get the x-coordinates of g(x)

→ By using the 2nd rule above

∴ g(x) is the image of f(x) after reflection across the y-axis

∴ The relationship between the graphs of the two functions is

    "They are reflections of each other across the y-axis"
