The ratio of employees who
play musical instruments to
employees who play sports is
3:20. If there are 40
employees who play sports,
how many employees play
musical instruments?

Answers

Answer:

Employees who play musical instruments = 6

Step-by-step explanation:

Given that:

Ratio of employees who play musical instruments to employees who play sports is 3 : 20

Number of employees who play sports = 40

Let,

x be the number of employees who play musical instruments.

Ratio = x : 40

As the relationship is proportional,

3 : 20 :: x : 40

Product of mean = Product of extreme

20x = 120

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{120}{20}\\x=6[/tex]

Hence,

Employees who play musical instruments = 6

What two numbers multiply to -32 and add up to 4

Answers

Answer:

-4 and 8

Step-by-step explanation:

-4 x 8 = -32

-4 + 8 = 4

The two numbers that multiply to -32 and add up to 4 are -8 and 4.

To find two numbers that multiply to -32 and add up to 4, we can use a factoring approach or trial and error.

Let's consider two numbers, x and y, such that:

xy = -32 (Equation 1)

x + y = 4 (Equation 2)

We need to find values of x and y that satisfy both Equation 1 and Equation 2 simultaneously.

By trying different pairs of numbers, we can find that -8 and 4 satisfy both equations:

-8 * 4 = -32 (Equation 1)

-8 + 4 = 4 (Equation 2)

Therefore, the two numbers that multiply to -32 and add up to 4 are -8 and 4.

What is the value of x?

Answers

X = 20

Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20

NOTES: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown."

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Mark regularly works 20 hours per week at a local restaurant from Monday through
Friday. He earns $14.25 per hour and receives double-time pay for working Saturdays.
Last week he worked his regular 20 hours, and an additional 4 hours on Saturday.
What will his total pay be for the week?

Answers

okay so we know that he worked his regular 20 hours so we can multiply pay times his hours ($14.25)x (20) which is $285 plus the 4 hours on Saturday. *add $14.25 plus $14.25 together because he gets paid double for overtime* ($28.50)x(4) which is $114. Then we add them both together $285+$114 = $399 which is your answer

Answer:

y-intercept: -5

Slope: 4

Equation: y = 4x - 5

Step-by-step explanation:

✔️ y-intercept (b):

When x = 0, y = -5. Therefore, the y-intercept (b) = -5. It is the point at which the y-axis cut across by the line. At this point, x is always zero.

✔️Slope using two points (0, -5) and (1, -1):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - (-5)}{1 - 0} = \frac{4}{1} = 4 [/tex]

Slope (m) = 4

✔️Equation in slope-intercept form y = mx + b:

Substitute m = 4, and b = -5 into y = mx + b

y = 4(x) + (-5)

y = 4x - 5
