Answer:

I think it's 15 students

Step-by-step explanation:

i think since 150 is half of 300 so in each class there should also be half of the people wearing red

Answer:

150 of 300, 150 is 50 % of 300 so 300/30 = 1 , so I think 15 of the students should be wearing red

Step-by-step explanation:

Answer: 200% increase

Step-by-step explanation:

Being an increase from 12inches to 36inches, we will calculate the percentage increase.

%increase = final length -initial length/initial length × 100%

Initial length = 12inches

Final length = 36inches

%increase = 36-12/12 × 100%

%increase = 24/12 × 100%

%increase = 200%

Answer:

200% increase

Step-by-step explanation:

percent change = [(difference between initial and final value) ÷ initial value] x 100

⇒ percent change = [(36 - 12) ÷ 12] x 100 = 200% increase

Answer:

D. 20 ÷ 6 − 4

E. 1/6(20 − 24)

F. (20−24) ÷ 6

Step-by-step explanation:

6(x + 4) = 20

6(x) + 6(4) = 20

6x + 24 = 20

     - 24  - 24

6x = -4

/6    /6

x = -4/6 or x = -2/3

D. 20 ÷ 6 − 4

20/6 - 4

20/6 - 24/6

-4/6 = -2/3

E. 1/6(20 − 24)

1/6(-4)

-4/6 = -2/3

F. (20 − 24) ÷ 6

- 4 / 6

-4/6 = -2/3

Replace x and y with the given values and solve the equations:

A) 3(5) + 2 = 17

B) 2(5)^2 = 50

C) (5-2)^2 = 9

Answer:

just replace the x and y in your problems with the given respective integers.

Step-by-step explanation:

x is 5, y is 2

a.

3x+y = 3×5 +2 = 15 + 2 = 17

b.

2x² = 2 × 5² = 2 × 25 = 50

c.

(x-y)² = (5-2)² = (3)² = 9

Answer:

see below

Step-by-step explanation:

Is there an operator (+, -, x, /) missing between 100 and 15?

Assume the expression is

=b4*10015/3

The order of operations says that multiplications and divisions are done as they occur from left to right.

The number in cell b4 will be multiplied by 10015, then that result will be divided by 3.

If the expression is supposed to be  =b4*100*15/3, then the order is

cell b4 is multiplied by 100, then that is multiplied by 15, then THAT is divided by 3.

Option D

Now we can apply quadratic formula to find two zeros

Answer:

[tex]\textsf{D.}\quad5x^2+8x-12=2x^2-x[/tex]

Step-by-step explanation:

Quadratic Formula

[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0[/tex]

A linear equation in the form [tex]y=mx+b[/tex] cannot be solved using the quadratic formula, as it is not a quadratic equation.

[tex]\textsf{A.}\quad 4x + 2 = 0[/tex]

This is a linear equation and therefore cannot be solved using the quadratic formula.

[tex]\begin{aligned}\textsf{B.}\quad 3x^2-4&=3x^2-4x\\\implies -4&=-4x\end{aligned}[/tex]

This is a linear equation and therefore cannot be solved using the quadratic formula.

[tex]\textsf{C.}\quad 2x=32[/tex]

This is a linear equation and therefore cannot be solved using the quadratic formula.

[tex]\textsf{D.}\quad5x^2+8x-12=2x^2-x[/tex]

[tex]\implies 3x^2+9x-12=0[/tex]

Therefore, this is a quadratic equation in the form [tex]ax^2+bx+c=0[/tex] and therefore can be solved quadratic formula.

a = 3, b = 9 and c = -12

Inputting these into the quadratic formula and solving for x:

[tex]\begin{aligned}\implies x &=\dfrac{-(9) \pm \sqrt{(9)^2-4(3)(-12)}}{2(3)}\\\\x& = \dfrac{-9 \pm \sqrt{225}}{6}\\\\x& = \dfrac{-9 \pm 15}{6}\\\\x&=\dfrac{6}{6},\dfrac{-24}{6}\\\\x&=1, -4\end{aligned}[/tex]

Answer:

Step-by-step explanation:

Supplementary angles add up to 180

∠1 + 50 = 180

∠1 = 180 - 50

∠1 = 130

∠3 +50 = 180   {Supplementary}

∠3 = 180 - 50

∠3 =130

⇒∠1 = ∠3 = 130

Answer:

supplementary means that < 1 and 50° together must be equal to an angle of 180°

so 180° - 50° = 130°

the second one its the same.. 50° + < 3 = 180°

so 180° - 50° = 130°

so you find out that < 1 = < 3

..if this m is meant like x and therefore this is an equation

m < 1 = m < 1 / ÷ < 1

m = m and that is true..

Slope of line passing through two points (x1,y1 ) and (x2 ,y2 ) is given by

m= y2-y1/x2 −x1

Since the line passes through (−2,5) and (6,4)

We have

Slope(m)= 4-5/6−(−2) =− 1/8

The interest rate in during the initial period is given from which the

monthly payment is calculated to be $1682.94

Response (approximate value):

The type of loan Jackie obtains is an Adjustable Rate Mortgage, ARM,

loan, which is a 4/2 ARM

Therefore;

The introductory interest rate of 5% is fixed for the first 4 years, and will

be adjusted every 2 years after the first four years.

[tex]Initial \ monthly \ payment, \ M = \mathbf{\dfrac{P \cdot \left(\dfrac{r}{12} \right) \cdot \left(1+\dfrac{r}{12} \right)^n }{\left(1+\dfrac{r}{12} \right)^n - 1}}[/tex]

Where;

M = The monthly payment during the initial period

P = The amount on loan = $313,500

r = 5% = 0.05

n = 30 × 12 = 360

Which gives;
