Answer:

Step-by-step explanation:

First calculate the total number of students in all the schools:

= 618 + 378 + 204  

= 1,200 students

Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.

North Middle school:  

= 618/1,200 * 20  

= 10 students

Central Middle School:  

= 378 / 1,200 * 20  

= 6 students

South Middle School:  

= 204/1,200 * 20  

= 4 students  

Answer: B reduction

Step-by-step explanation:

The blue triangle is the pre-image. (The original image before it was changed) The green triangle is the mapped image (the image after it was changed) we know this because of the ‘ marks after each point. So the original blue triangle was reduced in size to form the green triangle.

My answer:(K-6) (K+4)

Step-by-step explanation:Note:If this is wrong my apologies.Sorry if this doesn't help.

All i did to solve this math problem is that i factor k^2-2k-24 by using the AC method.

The factors of the quadratic equation by applying the factorization method are (k + 4) and (k - 6)

Used the concept of the quadratic equation which states that,

An algebraic equation with the second degree of the variable is called a Quadratic equation.

Given that,

The quadratic equation,

k² - 2k - 24

Now, apply the factorization method in the above equation,

k² - 2k - 24

k² - (6 - 4)k - 24

k² - 6k + 4k - 24

k (k - 6) + 4 (k - 6)

Therefore, the factors are,

(k + 4) (k - 6)

Answer:

y = 1/12x + b

Step-by-step explanation:

So lines that are perpendicular have a negative reciprocal slope.

If line c has a slope of -12, then line d has a slope of 1/12

So y = 1/12x + b would be perpendicular to c, where b is a constant

Answer:

1   1/4

Step-by-step explanation:

Just divide them, 3/4 divided by 3/5, then switch the fraction and sign.

Answer:

15/12

Step-by-step explanation:

3/4 divided by 3/5

That would become 3/4 times 5/3 because you take the reciprocal

3 x 5 = 15

4 x 3 = 12

So, 15/12 or 1.25

Answer:

7 million

Step-by-step explanation:

If you use your finger and continue the graph you will get to 7.\.

Answer:

7 million

Step-by-step explanation:

Take 2 points of the graph

(3,3) and (6,4)

the numbers on the x axis are 3 and 6

the numbers on the y axis are 3 and 4

Everytime the x axis goes up by 3, the y axis goes up by 1

Therefore, the slope is [tex]\frac{1}{3}[/tex]

If you continue the slope, you would get (12,6) and then (15,7)

Answer:

5k

Step-by-step explanation:

The interest accrued on the principal is $100.

Using the formula;

A = P( 1 + r/n)^nt

A - amount

P - Principal

r = rate

n = Number of times the interest is compound

t = time in years

Substituting values;

A = 4,300( 1 + 0.023/365)365 × 1

A =  $4400

Interest =  $4400 - $4,300 = $100

The annual percentage yield is obtained from;

APY=100 (1 + r/n )n – 1

APY=100 (1 + 0.023/365)^n - 1

APY= 100(0.023)

APY= 2.3 %

Answer:

$5.67

Step-by-step explanation:

$5.67

Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15  

For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost  

2.7 x 2.1 = 5.67  

Answer:

2 solutions

(-2,0) and (0,0)

Step-by-step explanation:

Given:

The point is (-5,7).

To find:

The image of the given point after 90 degrees counter clockwise rotation.

Solution:

If a point rotated 90 degrees counter clockwise, then

[tex](x,y)\to (-y,x)[/tex]

Let the given point is P(-5,7). Using the above rule, we get

[tex]P(-5,7)\to P'(-7,-5)[/tex]

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

Answer:

x = 14

BE = 6

Step-by-step explanation:

to find 'x':  BG = 1/2[(x-9) + (3x-13)]

BG = 4x-22 / 2

BG = 3x-25

3x-25 / 1 = 4x-22 / 2

cross-multiply:

4x-22 = 2(3x-25)

4x-22 = 6x-50

-2x = -28

x = 14

to find 'BE':  CB = BE

2x+4 = 7x-1

-5x = -5

x = 1

BE = 7(1) - 1

BE = 6

Answer:

x < 3

Step-by-step explanation:

Isolate the variable, x. Treat the < sign as an equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, add 1 to both sides of the equation:

4x - 1 (+1) < 11 (+1)

4x < 11 + 1

4x < 12

Next, divide 4 from both sides of the equation:

(4x)/4 < (12)/4

x < 12/4

x < 3

x < 3 is your answer.

Answer:

B

Answer:

x-10

Step-by-step explanation:

you have to do what is in the parenthesis first. Do distributive property to

-(x-8)

-(x)-(-8)= -x+8

now you have 5-(3-x+8)

Do distributive property again

5-3+x-8

x-8+2

x-10
