Answers

Answer 1

Answer:

okay so Y can be 6

and x can be 3

Step-by-step explanation:

The list below shows the tips earned by Cody while working at Olive Garden. $20, $45, $30.50, $46, $50 What is the mean of the tips earned by Cody?

Answers

Answer:

$38.30

Step-by-step explanation:

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50

Total number = 5

Mean = $191.50 / 5 = $38.30

Since lateral surface area means all the shapes except the base, we will ignore the square in the middle.

A=1/2(b*h)

A=1/2(10*3)

A=15in²

Now we will multiply the area by 4 or the number of other shapes besides the base.

to find out how many parts you have you add 3 and 2 together, this gives you 5, 36÷5=7 so for every 1 of each you have 7, 3×7=21, 2×7=14

Answer:

Step-by-step explanation:

F/L=3/2

F=3L/2

F+L=35, using F found above makes this become

3L/2+L=35

3L+2L=70

5L=70

L=14, since F=3L/2

F=3(14)/2

F=21

So she needs

Fruit juice=21 liters

Lemonade=14 liters

20 out of 800 products were found to be defective. At the same rate, how many defective parts will be found in 40,000 products? There would be Blank 1 defective parts out of 40000.

Answers

Answer: 1,000 products

Step-by-step explanation:

If 20 out of 800 products are found to be defective, the percentage of defective products would be:

= 20 / 800

= 2.5%

At this same rate of 2.5%, if there are 40,000 products instead of 800, the number of defective products would be:

= 2.5% * 40,000

= 1,000 products

The standard form of the equation of a parabola is x = y2 + 6y + 1. What is the vertex form of the equation? O A. x = (y + 3)2 - 8 O B. x = (y + 6)2-11 O C. x = (y + 6)2-35 O D. x = (y + 3)2-5​

Answers

Answer:

A

Step-by-step explanation:

Given

x = y² + 6y + 1

To complete the square

add/subtract ( half the coefficient of the y- term )² to y² + 6y

x = y² + 2(3)y + 9 - 9 + 1

  = (y + 3)² - 8

The vertex form of the equation of a parabola is,

⇒ x = (y + 3)² - 8

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The standard form of the equation of a parabola is,

⇒ x = y² + 6y + 1.

Now, We can simplify as;

⇒ x = y² + 6y + 1

⇒ x = y² + 6y + 9 - 9 + 1

⇒ x = (y + 3)² - 8

Thus, The vertex form of the equation of a parabola is,

⇒ x = (y + 3)² - 8

protocol for flushing a cooling water system at a nuclear reactor requires that a drain valve be opened while the fill pumps are active. the drain valve can empty the tank to thr cut-off in 10 minutes. the pump can fill the rank from the cut-off in 14 minutes. during the flushing process, how long will it take for the initially full tank to reach the cut-off level while following the protocol?​

Answers

Answer:

Step-by-step explanation:

drain empties 1/10 of the desired amount per minute

pump fills 1/14 of the desired amount per minute

when both are active, the net drain is 1/10-1/14 = 1/35 of the desired amount per minute

It takes 35 minutes to reach the cut-off level.
