Answer:

Step-by-step explanation:

Step one:

given

number of shirts= 500

cost of all the shirts= $12000

unit cost of shirt= 12000/500

                          =$24

the selling price = $30

the profit per shirt= selling price-cost price

30-24=$6

Required

% mark up

% mark up=( profit/cost price)*100

% mark up=( 6/24)*100

% mark up=0.25*100

% mark up=25%

Hence the % mark up is 25%

Answer:

Step-by-step explanation:

x + 87 + 20 = 180           {Angle sum property of triangle}

          x + 107 = 180

                 x = 180 - 107

                x = 73

1) Exterior angle of a triangle equals the sum of opposite interior angles or remote angles.

2) x = 63 + 86

  x = 149

Answer: 4(5+2) or 4(2+5)

Answer:

y = 3/4x + 12

Step-by-step explanation:

let equation of the line be y = 3/4x + b

sub (-8, 6):

6 = 3/4(-8) + b

12 = b

therefore equation of the line is y = 3/4x + 12

Answer:

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Step-by-step explanation:

We need to find equation of line that passes through the point (-8,6) and has a slope of 3/4 in general form.

The general form of linear equation is [tex]Ax+By+C=0[/tex]

First we will use slope-intercept form i.e, [tex]y=mx+b[/tex] to find equation and then write it in general form.

Where m is slope and b is y-intercept.

We are given slope = 3/4 but y-intercept is not given and we need to find.

Finding y-intercept

Using the point (-8,6) and slope m = 3/4 we can find y-intercept

[tex]y=mx+b\\6=\frac{3}{4}(-8)+b\\6=3(-2)+b\\6=-6+b\\b=6+6\\b=12[/tex]

So, y-intercept b is 12

Equation of line

The line has slope m=3/4 and y-intercept b is 12, the equation is:

[tex]y=mx+b\\y=\frac{3}{4}x+12[/tex]

General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:

[tex]\frac{3}{4}x-y+12=0[/tex]

Answer:

2. 8n. 8n. 8n. 8n

Step-by-step explanation:

[tex]2 {(8n)}^{4} = 2. 8n. 8n. 8n. 8n[/tex]

Equivalent expressions are expressions with equal value.

The equivalent expression of [tex]\mathbf{2\cdot(8n)^4}[/tex] is [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

The expression is given as:

[tex]\mathbf{2\cdot(8n)^4}[/tex]

Apply law of indices

[tex]\mathbf{2\cdot(8n)^4 = 2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

The above equation means that:

[tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex] is equivalent to [tex]\mathbf{2\cdot(8n)^4}[/tex]

Hence, the correct option is (d) [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

Answer:

Y = 3/5x + 2

Step-by-step explanation:

Answer:

[tex]y=\frac{3}{5} x+2[/tex]

Answer:

The probability that X is greater than Y is 0.5754.

Step-by-step explanation:

It is provided that,

[tex]X\sim N(184.09, 39.37)\\\\Y\sim N(171.93, 50.88)[/tex]

It is also provided that X and Y are independent.

We need to compute the value of:

P (X > Y) = P (X - Y > 0)

Compute the mean and standard deviation of (X - Y) as follows:

[tex]E(X-Y)=E(X)-E(Y)=184.09-171.93=12.16\\\\SD(X-Y)=\sqrt{V(X-Y)}=\sqrt{V(X)+V(Y)}=\sqrt{39.37^{2}+50.88^{2}}=64.33[/tex]

Compute the the value of P (X > Y) as follows:

[tex]P(X>Y)=P(X-Y>0)\\\\=P(\frac{(X-Y)-E(X-Y)}{SD(X-Y)}>\frac{0-12.16}{64.33})\\\\=P(Z>-0.19)\\\\=P(Z<0.19)\\\\=0.57535\\\\\approx 0.5754[/tex]

Thus, the probability that X is greater than Y is 0.5754.

Answer:

x = 20°

y = 19°

Step-by-step explanation:

The first two angles that are in the 2nd Quadrant:

2x - 3

3x - 7

The rule states that the two angles are complimentary angles that form an angle of 90°. So,

(2x - 3) + (3x - 7) = 90

2x - 3 + 3x - 7 = 90

2x + 3x - 3 - 7 = 90

5x - 10 = 90

5x = 90 + 10

5x = 100

x = 100 ÷ 5

x = 20

Another rule applies here, vertical angles are equivalent to each other.

So,

2x - 3 = 2y - 1

2(20) - 3 = 2y - 1

40 - 3 = 2y - 1

37 = 2y - 1

37 + 1 = 2y

38 = 2y

38 ÷ 2 = y

19 = y

2.) Simplify  -9+1−9+1  to  -8−8.

-8<8(r-17)−8<8(r−17)

3.) Divide both sides by 88.

-1<r-17−1<r−17

4.) Add 1717 to both sides.

-1+17<r−1+17<r

5.) Simplify  -1+17−1+17  to  16.

Option D is correct option.

Step-by-step explanation:

We are given: [tex]f(x)=x^2+2x[/tex]

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

[tex]f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h[/tex]

Finding f(x+h) we get:

[tex]f(x+h)=x^2+2xh+h^2+2x+2h[/tex]

Option D is correct option.

Answer:

6 girls were there are first

Step-by-step explanation:

use trial and error. divide 1200 by a random number like 10, and see how much they each had to pay. If we guessed 10, then each girl would hypothetically pay 120 pounds. If four girls left, then 1200/6 would be 200 pounds. there was only a 60 pound increase here, not a 400 pound one.

I checked 1200/6 which equals 200 pounds per girl. If 4 girls left, then it would be 600 pounds for the 2 remaining girls. the rent increased from 200 to 600 which is a 400 pound increase.

Answer:

Step-by-step explanation:

If Daniela has 2 1/4 basketball games left to play in a tournament, and she has 3/4 gallon of water left to drink, since she drinks the same amount in each game, we can say;

2 1/4 games = 3/4 gallons

To calculate how much he has to drink in a game, this can be expressed as;

1 game = x gallon

Solve for x;

2 1/4 games = 3/4 gallons

1 game = x gallon

Cross multiply

3/4 = 2 1/4x

3/4 = 9/4 x

9x/4 = 3/4

cross multiply;

9x * 4 = 4*3

36x = 12

x = 12/36

x = 1/3

Hence she can drink 1/3 gallons of water in each game.

Answer:

500

Step-by-step explanation:

First of, multiply all of the number by 10 to remove the decimal place ( this will make it less confusing)

So 102.3 x 10= 1023

4.7 x 10 = 47

You will have to round each of the numbers to 1 significant figure (sf) :

1023 round to 1 sf will be 1000

47 rounded to 1 sf will be 50

Then multiply these numbers:

1000 x 50 = 50000

Finally divide by 100 to get back the decimal places

(You divide by 100 because you multiplied by 10 twice, 10 x 10= 100)

You get 500
