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?

Answer:

21%

Step-by-step explanation:

So we have to use percent change

The formula is subtracted/original multiply 100=percent change

so she added a $5.04 tip

5.04/24=0.21, then multiplied by 100=21

so she tipped 21%

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

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.

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

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 ?

Given :

Need to find :

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

Good luck !

Answer:

marks awarded for each correct answer = 4

marks awarded for each incorrect answer = -2

No.of Sunil's correct answer = 6

therefore, mark of Sunil's correct answer = 6 x 4 = 24

No.of Sunil's incorrect answer = 4

therefore, mark of Sunil's incorrect answer = 4 x -2 = -8 (here + and - is                                                                                                                  multiplied therefore the final answer will be -)

Sunil's total score = 24(positive marks) - 8(negative marks)

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.

x=8.385

Step-by-step explanation:

Angle EBD is a right angle since it's facing the diameter ED

Hence triangle BED is a right isosceles triangle since we also know that EB=BD

so A is the midpoint of ED since it's the center of the circle and ED is a diameter

which implies ED=2×AD=2×6=12

Using the Pythagorean theorem on a right isosceles triangle which states:

a²+b²=c²

x²+x²=12²

2x²=144

x²=72

x=√72=8.485

Answer:

Step-by-step explanation:

Let length be x

So breadth will be 1/4x

2(x+1/4x)=60

x+1/4x=60/2=30

find lcm and the lcm would be 4 and make denominators equal and add it

4/4x+1/4x=30

5/4x=30

x=30*4/50=6*4=24

Therefore the length is 24/4=6cm and breadth is 24cm.

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

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]

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.

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.

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
