Megan is in a musical production. She was at practice for 2 hours yesterday and 3 hours today. Altogether she spent of her practice hours dancing. How many total hours did Megan spend dancing yesterday and today?​

Given:

Total Number of teaspoons of peppercorns = 27

Amount of teaspoons you need for one serving of brief brisket = 0.25

Let's find the amount of servings can be made.

To find the amount of servings that can be made, apply the formula:

Thus, we have:

Therefore, 108 servings can be made.

ANSWER:

108

Answer:

  C.  100

Step-by-step explanation:

If 60 songs are played in 3 hours, 80 songs in 4 hours, and 120 songs in 6 hours, you want to know the number played in 5 hours.

Considering the rate of change of songs per hour, we find ...

  hours 3-4: 80-60 = 20 songs, over the 1-hour period

  hours 4-6: 120 -80 = 40 songs, over the 2-hour period

It appears that the number of songs being played is steady at 20 songs per hour. Then 5×20 = 100 songs were played in 5 hours.

Step 1:

Let the number of hours = m

Flat fee = $25

Fees charge per hour = $30

Step 2:

Money Ronnie made from his first customer = $175

Write an equation.

30m + 25 = 175

Step 3:

Solve the equation.

Final answer

5 hours

The two lines are neither parallel nor perpendicular.

What is condition for perpendicular, parallel?

if two given lines are parallel, perpendicular, or neither, we need to compare their slopes. For this, we need to make sure that their equations are in the form y = mx + b. This represents the equation of a straight line in the slope-intercept form, where m is the slope and b is the y-intercept.

If the given lines have the same slope, they’re parallel to one another. On the other hand, if they have slopes that are opposite reciprocals, i.e., the slopes have opposite signs and are flipped fractions of one another, they are perpendicular to each other. Else, they are neither.

The given lines are

- 3x + 6y = 12 or, y = (1/2)x + 2 ... (1)

y = - 3x + 10 ... (2)

The gradient of the lines (1) and (2) are 1/2 and (- 3) respectively.

Since the gradients are not equal, the lines are not parallel and also since (1/2) × (- 3) ≠ - 1, the lines are not perpendicular to each other.

Hence we can conclude that the given two lines are neither parallel nor perpendicular.

The slope of a line from given points (19,-16), (-7, -15) is - 1/26

Slope :

In Mathematics, Slope of a line defined as the direction of the line and the change in y-coordinate with respect to x - coordinate. Slope of a line is denoted by 'm'

The formula for slope of a line which passes through the points (x₁, y₁) and (x₂, y₂) is given by Slope (m) =  (y₂– y₁)/(x₂ – x₁)

Here, we have pair of points (19,-16), (-7, -15)

Take (x₁, y₁) = (19,-16) and (x₂, y₂) = (-7, -15)

Slope (m) = [-15 -(-16) ] / [ -7 -19 ]

= [ - 15+16] / [ -26 ]  

= [ 1 ] / [ -26 ]  

= - 1/26

Therefore,

The slope of line from given points (19,-16), (-7, -15) is - 1/26

Answer:

The 14-inch pizza cut into 8 slices.

Explanation:

The deep-dish pizza forms a cylindrical shape.

To make comparisons, we find the volume of each slice of pizza in each case.

Case 1

A 14-inch pizza that is 3 inches deep.

Radius = 14/2 = 7 inches

Height = 3 inches

Since it is cut into 8 slices:

Case 2

A 16-inch pizza that is 2 inches deep.

Radius = 16/2 = 8 inches

Height = 2 inches

Since it is cut into 7 slices:

Conclusion

The volume of a slice of pizza in the first case (the 14 -inch pizza cut into 8 slices) is larger, therefore it should be chosen to get the most food.

Given the function :

we need to find the value of 3f(5) x f(2)

so, to find the value of f(5), substitute with x = 5 at the given function

And to find the value of f(2) , substitute with x = 2 at the given function

so,

[tex]t=100 \left(1-\frac{V}{50} \right)^2\\\\\frac{t}{100}=\left(1-\frac{V}{50} \right)^2[/tex]

Since time is positive, we take the positive square root.

[tex]\frac{\sqrt{t}}{10}=1-\frac{V}{50}\\\\\frac{\sqrt{t}}{10}-1=-\frac{V}{50}\\\\50-5\sqrt{t}=V\\\\\therefore f^{-1}(V)=\boxed{50-5\sqrt{V}}[/tex]

Given the function [tex]f(x) = \left \{ {{5x-4, \ \ \ x\leq 1} \atop {-x+4, \ \ \ \ \ x > 1}} \right.[/tex], the function is not continuous at x = 1.

A function is said to be continuous if it can be drawn without picking up the pencil. Otherwise, a function is said to be discontinuous.

Given function,

[tex]f(x) = \left \{ {{5x-4, \ \ \ x\leq 1} \atop {-x+4, \ \ \ \ \ x > 1}} \right.[/tex]

We need to check the continuity of the function f(x) at x = 1. At all other points, it is continuous.

f(x) at x = 1 : 5x - 4 = 5*1 - 4 = 5 - 4 = 1

f(x) at x < 1 : 5x - 4 = 5*1 - 4 = 5 - 4 = 1

f(x) at x > 1 : -x + 4 = -1 + 4 = 3

Since, f(x) at x < 1  ≠ f(x) at x > 1, therefore, f(x) is not continuous at x = 1.

The same is also visible from the graph attached below. There is a disruption at x = 1, the graph is not a smooth line.

Option C is the answer.

The value of x in 42/100 of x over 35 based on the computation is 14.7.

It should be noted that a fraction simply means a number that's not a whole number.

Based on the information, we want to calculate 42/100 × x/35. This will be illustrated thus:

= 42/100 × x/35.

Cross multiply

(100 × x) = (42 × 35)

100x = 1470

Divide through by 100

100x / 100 = 1470 / 100

x = 14.7

Answer:

Step-by-step explanation:

Answer:

[tex]{ \tt{(5)(3) - (2 - 7) \div 4}}[/tex]

- We are going to simplify the expression using BODMAS

- From our expression, relating it to BODMAS, Brackets come first, so let's first operate the brackets

[tex] = { \tt{(5 \times 3) - ( \frac{2 - 7}{4}) }} \\ \\ = { \tt{15 - ( - \frac{5}{4} )}} \\ \\ = { \tt{15 + 5 \div 4}}[/tex]

- Then in our last expression, Division comes next

[tex] = { \tt{15 + \frac{5}{4} }} \\ [/tex]

- Then addition comes last

[tex] = { \tt{ \frac{65}{4} }} \\ [/tex]

- Simplifying our answer into mixed fraction and decimal format;

Answer: 19 cm

Step-by-step explanation:

Substituting into the formula for the area of a trapezoid,

[tex]\frac{1}{2}(x-4)(x+4+x+9)=99\\\\\frac{1}{2}(x-4)(2x+13)=99\\\\(x-4)(2x+13)=198\\\\2x^2 +5x-250=0\\\\(2x+25)(x-10)=0\\\\x=-12.5, 10[/tex]

However, as x must be positive (since length must be positive), x=10. This means the length of the longer base is 19 cm.

The percent of people that were completely satisfied (%PS) can be calculated with the formula:

Where PS is the number of persons that were completely satisfied and TP is the total number of persons, in this case, the total number of persons is the sum of each number of persons from each category:

And as we can see from the figure, the number of completely satisfied people is 1100, then the percent of people that were completely satisfied is:

The percent of people that were completely satisfied is 55%

You just have to divide 1100 by the total people which is 2000, and then just multiply by 100, and that's it

A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

Here the domain of the relation is {3,x,9,5}.

The given relation is a function only if x not takes any of the value 3, 9 or 5.

So, option B is correct.

Using the uniform distribution, it is found that:

a) The probability that the friend is between 10 and 20 minutes late is of 1/3.

b) There is a 30% probability that the friend will arrive within 9 minutes.

The uniform has two bounds, a and b, and each outcome of the distribution is equally as likely.

From the image given at the end of the answer, the bounds are given as follow:

a = 0, b = 30.

The probability of finding a value between c and d in the distribution is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

Hence, the probability that the friend is between 10 and 20 minutes late is given as follows:

P(10 <= X <= 20) = (20 - 10)/(30 - 0) = 1/3.

The 30th percentile of the distribution, which is what item b is asking, is given as follows:

0.3 x (30 - 0) = 0.3 x 30 = 9 minutes.
