There are 380 light bulbs lined up in a row in a long room.
Each bulb has its own switch and is currently switched off.
Each bulb is numbered consecutively from 1 to 380. You
first flip every switch. You then flip the switch on every
second bulb(turning off 2, 4,6...). You then flip the switch
on every third bulb (3, 6, 9...). This continues until you
have gone through the process 380 times.

Answers

Answer 1

Bulb 2 was activated 760 times throughout the process.

How to calculate how many times light bulb #2 was activated?

To calculate how many times light bulb #2 was activated, we must identify how many times it is activated in each process.

Based on the information provided, bulb two has the following activity.

Power on oncePower off once

According to the above, bulb #2 is activated 2 times each process. So to know how many times it is activated in total, we must multiply the number of times it is activated in each process by the total number of processes (380).

380 × 2 = 760

Note: This question is incomplete because the question is missing. Here is the question:

After repeating this process 380 times, how many times was light bulb 2 activated?

nine times a number y plus seven is equal to a number y . Write the word sentence as an equation.

PLZ HELP

Answers

Answer: 9y + 7 = y

Explanation:

The phrase, "nine times a number y" is "9y" in the form of an equation. When any term is by a number, they are meant to be multiplied together. So, "9y" means "9 times y".

The phrase, "plus seven" simply means to add seven.

The phrase, "equal to number y" is "= y" because "number y" refers to that term.

And so, all together, you get 9y + 7 = y.

  126.7 if B=80

  93.3 if B=70

Step-by-step explanation:

Let F represent the student's score on the final exam, and let B represent the percentage required for a grade of B. Then we must have ...

  0.60(61) +0.10(54) +0.30F = B

  B = 0.30F +42

  F = (B -42)/0.3

__

If a grade of B requires 80 points or more, then the required grade on the final is ...

  F = (80 -42)/0.3 = 38/0.3 = 126 2/3

The student must get 126.7% on their final to achieve an overall average of 80.

__

If a grade of B requires 70 points or more, then the required grade on the final is ...

  F = (70 -42)/0.3 = 28/0.3 = 93 1/3

The student must get 93.3% on their final to achieve an overall average of 70.

What is the horizontal and vertical shift for the absolute value function below?
f(x) = |x -5|+ 1

Answers

Answer:

Moving to the right by 5 units

Moving up by 1 unit

Step-by-step explanation:

The basic absolute value function is f(x) = |x|

The graph vertex is at the origin.

Adding a value inside the absolute value brackets changes the vertex of the graph horizontally.

Adding a term moves it to the leftSubtracting a term moves it to the right

Adding a value outside the absolute value brackets changes the vertex vertically.

Adding a term moves it upSubtracting a term moves it down

Here, in the absolute value, we are subtracting by 5, so we move to the right 5

Outside the brackets, we are adding 1, so we move up 1.
