There are 300 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 270. 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,. ). This

continues until you have gone through the process 300

times.

And how many of the light bulbs are illuminated now?

Answers

Answer 1

Flipping the bulbs is an illustration of sequence and patterns

17 bulbs would remain on.

How to determine the number of bulbs that will be on?

The sequence of turning the bulbs off and on, would change the state of the bulbs until the 300th process.

While changing the state of the bulbs, the bulb at the perfect square positions would remain on.

There are 17 perfect square numbers between 1 and 300 (inclusive)

Hence, 17 bulbs would remain on.

A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day's guard duty equally. How long will each knight spend on duty? Record your answer in minutes

Answers

Answer:

≈206 Minutes

Step-by-step explanation:

We know that the castle has to be guarded for 24 hours a day. Since there are 60 minutes in an hour, that means it must be guarded for 1,440 minutes (60 * 24 = 1,440). If we split this evenly between each of the 7 knights, through division, we know that they must each be on guard for 205.714285714 minutes, or approximately 206 minutes.

find the circumference of a circle whose radius is 3 3/4 ft.

Answers

Applying the expression for the circumference of a circle we found the circumference to be 23.565 ft

Mensuration of flat shapes

Given Data

Radius =  3 3/4 ft

Let us first convert to proper fraction

Radius = 15/4 ft

We know that the expression for the circumference of circle is given as

Circumference = 2πr

Substituting our given data for radius we have

Circumference = 2*3.142*15/4

Circumference = 94.26/4

Circumference = 23.565 ft

An isosceles triangle has an angle that measures 100°. What measures are possible for the
other two angles? Choose all that apply.
80 100 40 50

Answers

The only measure that is possible for the other two angles is 40 degrees.

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

Let's call the two other angles in the isosceles triangle "x". We know that the sum of the three angles in a triangle is always 180 degrees. Therefore, we can set up an equation:

100 + x + x = 180

Simplifying this equation, we get:

2x + 100 = 180

Subtracting 100 from both sides, we get:

2x = 80

Dividing both sides by 2, we get:

x = 40

So the other two angles must both measure 40 degrees.

None of the other choices (80, 100, or 50 degrees) are possible for the other two angles in an isosceles triangle with one angle measuring 100 degrees.

Therefore, the only measure that is possible for the other two angles is 40 degrees.

The sales team at an electronics store sold 48 computers last month. The manager at the store wants to encourage the sales team to sell more computers and is going to give all the sales team members a bonus if the number of computers sold increases by 30% in the next month. a) What is the amount of increase in computers needed? b)What is the new amount of computers the team must sell?

Answers

Answer: a. 14 Computers

b. 62 Computers

Step-by-step explanation:

a) What is the amount of increase in computers needed?

Number of Computers sold last month = 48

Percentage increase required = 30%

Amount of increase in computers needed= 30% × 48

= 0.3 × 48

= 14.4

= 14 approximately

b)What is the new amount of computers the team must sell?

This will be the amount of Computers sold last month plus the increase.

= 48 + 14

= 62 Computers

(-4,1); perpendicular to y= -5/6x +3

Answers

Answer:

y = (6/5)x + 29/5

Step-by-step explanation:

To avoid confusion please enclose the fractional exponent inside parentheses:  y= -5/6x +3 =>  y= (-5/6)x +3

The new line is to be perpendicular to the given line (above).  The slope of this new line must be the negative reciprocal of (-5/6), which is (6/5).

Usig the slope-intercept formula, we get y = mx + b, or

1 = (6/5)(-4) + b

The LCD here is 5.  Multiplying all 3 terms by 5, we get:

5 = 6(-4) + 5b, or

5 = -24 + 5b, or

5b = 29

Then b = 29/5, and the desired equation is:

y = (6/5)x + 29/5

A bag has three marbles: one red, one blue, and one yellow. The marbles are pulled from the bag one at a time without replacing them. In how many different orders could the marbles be pulled from the bag?

Answers

The number of different orders that the marbles can be pulled from the bag is 6 ways

Combination and permutation of numbers

If a bag contains one red, one blue, and one yellow, then the total number of marbles contained is 3 marbles.

If the marbles are pulled from the bag one at a time without replacing them, the number of different orders that the marbles can be pulled from the bag is expressed as:
[tex]3C_1=\frac{3!}{(3-2)!} \\3C_1=\frac{3!}{1!}\\ 3C1=3! = 6ways[/tex]

Answers

Answer:

Commutative Property of Addition: to change the order of numbers in an addition or multiplication operation does not change the sum or the product.

New expression with property used: 5(2j + j + 3)

Combine like terms:  when combining like terms, add their coefficients

The like terms are 2j and j.  Add their coefficients: 2 + 1 = 3, which means that the combination of like terms is 3j.

New expression with property used:  5(3j + 3)

Distributive Property of multiplication over addition: multiplying a sum by a number gives the same result as multiplying each added term by the number and then adding the products together.

So 5(3j + 3) = 5 · 3j + 5 · 3 = 15j + 15

New expression with property used:  15j + 15

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equations are given below.

y = -x + 3                  ...1

y = 4x - 2                 ...2

From equations 1 and 2, then we have

4x - 2 = - x + 3

4x + x = 2 + 3

5x = 5

x = 1

Then the value of 'y' is given as,

y = - 1 + 3

y = 2

The solution of the linear equations y = -x + 3 and y = 4x - 2 will be (1, 2). Then the correct option is B.

A hotel has a rectangular-shaped meeting room that is 13.4 yds. wide and 15.1

yds. long. If carpet costs $1.71 per ft^2

, what would be the cost of carpeting the

meeting room?

Answers

✯ Appropriate Question -

A hotel has a rectangular shaped meeting room that is 13.4 yards wide and 15.1 yards long. If the carpenter cost $ 1.71 per feet² what would be the cost of carpenting the room ?

✯ Explanation -

Given :

Length of the meeting room = 15.1 yardBreadth of the meeting room = 13.4 yardRate of carpenting per feet² = $ 1.71

Need to find :

Cost of carpenting the room.

Solution :

THIS QUESTION IS BASED ON MEANSURATION TO SOLVE THIS QUESTION FIRST WE WILL CALCULATE THE AREA OF THE MEETING ROOM AND THEN WE WILL CALCULATE THE COST OF CARPENTING THE MEETING ROOM.

Calculating the area of the meeting room

[tex] \star \: \large \boxed{\sf{ Area_{(rectangle)} = Length × Breadth }}[/tex]

[tex] \large\rm{ Area_{(rectangle)} = (15.1 × 13.4) yard² = 202.34 \: yards²}[/tex]

Area of the meeting room = 202.34 yard²

Calculating the cost of carpenting the meeting room

First we will convert yards into feet

We know,

1 yard = 3 feet

202.34 yard = 202.34 × 3 = 607.02 feet

Now calculating the cost of carpenting the meeting room

Rate of carpenting = $ 17.1 per feet²

Cost of carpenting = $ ( 17.1 × 607.02) = $10,380.04

Final Answer -

Cost of carpenting the meeting room = $10,380.04.
