4. A sum of money is divided among Khairul, Michael and Ethan in the ratio 6:4:5. After Khairul
gives $30 to Michael and $15 to Ethan, the ratio becomes 7: 6:7. Find the amount of money Khairul
had initially​

Step-by-step explanation:

A case of paper cups costs $408 / 17 = $24.

5 more cases => 22 cases of paper cups total.

Hence the total cost will be 22 * $24 = $528.

Answer:

$528

Step-by-step explanation:

We find the unit rate of the cost per case.

$408 / 17 cases = $24/case

Each case costs $24.

Adding 5 cases to 17 cases, the order will be for 22 cases.

22 cases * $24/case = $528

Answer: $528

Answer:

0.35

Step-by-step explanation:

The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: The probability of customers getting a haircut is 87% and the probability that the customers that have a haircut also get their hair colored are 24%

Thus the conditional probability that a customer who has a hair cut also gets his hair colored is

P( haircut/hair colored )= 87%×24%

                                      =0.87×0.24

                                      =0.2088

Hence, The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

Answer:

The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

Step-by-step explanation:

We know that when a number let say 'n' get multiplied by '1', it remains unchanged.

i.e.

The number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.

Given the number

-12/13

Multiply the number '-12/13' by '1'.

i.e.

-12/13 × 1 = -12/13

1 × -12/13 = -12/13

Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.

Therefore, option (B) is true.

Step-by-step explanation:

suppose the initial cost to be x

it was increased by 6.5%

so, since the price increased is 117

117=6.5% of x

117=(6.5/100) . x

117 . 100=6.5 x

x=11700/6.5

x=1800

Step-by-step explanation:

Answer:

A) The number of wallpapers needed to cover the walls is 6 double roll wall papers

B) The number of wall paper border rolls needed is 3 rolls

Step-by-step explanation:

A) The given parameters are;

The dimensions of the room are 9 ft. by 12 ft. by 8 ft. high,

The area one double role wallpaper covers = 60 ft.²

Therefore, we have;

The area of the room wall = 12 × 8 × 2 + 9 × 8 × 2 = 336 ft²

The number of double rolls of wallpaper to be used = Area of wall/(area of wallpaper) = 336/60 = 5.6

Therefore, given that the wall papers are sold in single units, we round up to the next whole number of units to get;

The number of wallpapers needed to cover the walls = 6 double roll wall papers

B) The borders of a wallpaper are installed parallel (and installed along) to the ceiling line

Therefore, the amount of wallpaper border required is given as follows;

Wall paper border length required = 2 × Length of the room + 2 × Width of the room

∴ Wall paper border length required = 2 × 9 ft. + 2 × 12 ft. = 42 ft.

The size of each wall paper border sold = 5 yd. = 15 ft.

Therefore;

The number of wall paper border rolls required = 42 ft./(5 yd.) = 42 ft./(15 ft.) = 2.8 rolls

Therefore, we round up to get the number of wall paper border rolls needed as 3 rolls of wall paper borders.

Step-by-step explanation:

Alyssa starts with $40 and saves $10 each week. This can be written as:

= 40 + 10x

Bill has $24 and saves $12 each week. This can be written as:

= 24 + 12x

where, x = number of weeks

a. Bill will never have more money than Alyssa.

False.

From the 9th week, Bill will have more money than Alyssa. To check goes below.

Alyssa = 40 + 10x = 40 + 10(9) = 40 + 90 =$130

Bill = 24 + 12x = 24 + 12(9) = 24 + 108 = $132

b. Bill's savings can be represented by the equation = 12 + 24 where x is the number of weeks and y is his savings.

False.

Bill savings can be represented by:

= 24 + 12x

where, x = number of weeks

c. Alyssa and Bill will have the same amount of money at Week 6.

False.

Alyssa = 40 + 10x

= 40 + 10(6)

= 40 + 60

= $100

Bill = 24 + 12x

= 24 + 12(6)

= 24 + 72

= $96

Answer:

If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600.

Step-by-step explanation:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Answer:

A' = (-1, -1)

Step-by-step explanation:

Rule for the dilation of any point A(x, y) about the origin by a factor of k is given by the rule,

A(x, y) → A'(kx, ky)

From the graph attached,

Coordinates of point A are (-3, -3) and it is dilated by a scale factor of [tex]\frac{1}{3}[/tex] about the origin then the coordinates of the image point A' will be,

A(-3, -3) → [tex]A'(-3\times \frac{1}{3},-3\times \frac{1}{3})[/tex]

             → A'(-1. -1)

Therefore, coordinates of A' = (-1, -1) is the answer.

Answer:

That will be 1/14 points

Step-by-step explanation:

==============================================

Work Shown:

1/4 = 0.25

1 & 1/4 = 1 + 1/4 = 1 + 0.25 = 1.25

The stock dropped by 1.25 points each day for 5 days

It dropped a total of 5*1.25 = 6.25 = 6 & 1/4 points.

------------

Alternative method:

5*(1 & 1/4) = 5*(1 + 1/4)

5*(1 & 1/4) = 5*1 + 5*(1/4)

5*(1 & 1/4) = 5 + 5/4

5*(1 & 1/4) = 5*(4/4) + 5/4

5*(1 & 1/4) = 20/4 + 5/4

5*(1 & 1/4) = (20+5)/4

5*(1 & 1/4) = 25/4

5*(1 & 1/4) = (24+1)/4

5*(1 & 1/4) = 24/4 + 1/4

5*(1 & 1/4) = 6 + 1/4

5*(1 & 1/4) = 6 & 1/4

We get the same answer as before.

500 x^11

Step-by-step explanation:

Answer:

500x^11

Step-by-step explanation:

Using PEMDAS first get rid of parenthesis

(2x^4)^2 is the same as 2x^4 * 2x^4 or 4x^8

(5x)^3 is the same as 5^3 * x^3 or 125x^3

multiply the two together, remember exponents on like terms add together

125*4 = 500

x^8 * x^3 = x^11

multiply together

500x^11
