Last year at a certain high school, there were 50 boys on the honor roll and 100 girls on the honor roll. This year, the number of boys on the honor roll decreased by 8% and the number of girls on the honor roll decreased by 15%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary). pls help

Answer:

I have that same question on my extra credit!

Step-by-step explanation:

I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:

Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:

Ivy’s explanation: I lined up the numbers to subtract.

 176.3

- 15.75

 18.8

Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.

 176.30

- 15.75_

 161.45

Jose’s explanation: I lined up the two decimals according to place value.

176.3

- 15.75

 161.45

An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.

15.75 + 0.25 = 16

16 + 4 = 20

20 + 150 = 170

170 + 6 = 176

176 + 0.3 = 176.3

I rearranged the underlined numbers to make them easier to add: .

150 + 6 + 3 + 0.25 = 163.25

Explain each student’s mistake and solve the problem correctly.

Answer:

2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 6y = - 18 ( subtract 3x from both sides )

6y = - 3x - 18 ( divide all terms by 6 )

y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2

Slope of the line perpendicular to given line 3x + 6y = –18 is 2

The slope intercept of a line is given : y = m x+ c

y is y coordinate, x is x coordinate, m is the slope of the line

c is y- intercept of the line

If given that the slope of two lines are m₁ and m₂ then these lines are perpendicular, if the product of their slopes is -1 or  m₁ *m₂ = -1

Given line is 3x + 6y = –18

Subtract 3x from both sides

⇒ 3x +6y -3x = -3x-18

⇒  6y = -3x-18

⇒ y =(-3/6)x -18 /6 = (-1/2) x -3

comparing it with slope intercept , slope = -1/2

let the slope of line perpendicular to given line is m

then m.(-1/2) = -1

   ⇒ m = 2

∴Slope of the line perpendicular to given line is 2

Answer:

A

Step-by-step explanation:

hi! this is modus ponens. modus ponens is a form of assumption, and modus tollens denies the initial statement. modus ponens is like saying if A, then B occurs as well. if A is proven to be true, B must also be true. this makes sense in this situation because it says if an animal is a dog, then it barks (if A, then B). the animal barks, so it is a dog (A is true, so B must also be true).

Answer:

4[tex]\sqrt{13}[/tex]

4[tex]\sqrt{13}[/tex] + 8

4[tex]\sqrt{13}[/tex] + 16

Step-by-step explanation:

as per the given information:

shorter leg = x

longer leg = x + 8

hypotonuse = x + 8 + 8

remember the Pythagorean theorem, which states

x^2 + y^2 = n^2

where x and y are the legs and n is the hypotenuse

so now one can set up an equation:

x^2 + ( x + 8 )^2 = ( x + 16 ) ^2

simplify and solve using inverse operations:

first preform the square

x^2 + x^2 + 16x + 64 = x^2 + 32x + 256

then preform inverse opertations and simplify

2x^2 + 16x + 64 = x^2 + 32x + 256

-x^2                       -x^2

x^2 + 16x + 64 = 32x + 256

       -16x            -16x

x^2 + 64 = 16x + 256

       - 64             -64

x^2 = 16x + 192

-16x     -16x

x^2 - 16 = 192

x^2 -4^2 = 192

remember the differnt ways of writing a special square

(x - 4) (x + 4) = 192

x = 4[tex]\sqrt{13}[/tex]

now add 8 to find the longer leg

4[tex]\sqrt{13}[/tex] + 8

an add another 8 to find the hypotenuse

4[tex]\sqrt{13}[/tex] + 8 + 8

4[tex]\sqrt{13}[/tex] + 16

Answer:

p=9 m=21 x= - 30

Step-by-step explanation:

p=9

m=21

x= - 30

Step-by-step explanation:

1) 3p + 5 = 14

3p = 14 - 5

3p = 9

p = 9/3

⇢ p = 3

2)

m/7 - 3 = 0

m/7 = 3

m = 3 × 7

⇢ m = 21

3) 8 + x/2 = -7

x/2 = -7 - 8

x/2 = - 15

⇢ x = -30

Answer:

y = x/4

Step-by-step explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.

Answer:

3x + 2 = 14

3x + 2 - 2 = 14 - 2

3x = 12

3x/3 = 12/3

x = 4

Step-by-step explanation:

3x + 2 = 14

subtract 2 from both sides

3x + 2 - 2 = 14 - 2

combine like terms.

3x = 12

divide both sides by 3

3x/3 = 12/3

x = 4

Answer:

4y^4 + 6y = 256y + 6 = 262y

Step-by-step explanation:

Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6

Simplify the first term; 4^4 = 256

Now, add 6; 256 + 6 = 262

Add back in the variable; 262y

Answer:

2y(2y+3)

2y(2y + 3) factor 2y out of 2y(2y)+2y(3)

Step-by-step explanation:

By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference of a circle is equal to pi times the diameter (c = πd).

Answer:

1) The equation for computing Gustin's profit per seminar is given as follows;

The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost

2) The number of new accounts is a continuous random variable

Step-by-step explanation:

1) The number of individuals that attend each of Gustin's seminar = 25 individuals

The cost of each seminar = $3,300

On average the commission on the first-year for each opened account = $5,100

The probability of opening an account by an attendee of each seminar = 0.01

The profit = Revenue - The cost of each seminar

The revenue = (The number of Newly Opened Accounts) × (Commission on each account)

∴ The revenue = (The number of Newly Opened Accounts) × $5100

Therefore, the equation for finding Gustin's profit per seminar is given as follows;

The profit = (The number of Newly Opened Accounts) × Commission - Seminar cost

The profit = (The number of Newly Opened Accounts) × $5100 - $3,300

The number of Newly Opened Accounts = (The number of attendee) × (The probability of an attendee opening an account)

The number of Newly Opened Accounts = 25 × 0.01 = 0.25

The number of Newly Opened Accounts = 0.25

The profit = 0.25 × $5100 - $3,300

The revenue = 0.25 × $5100 = $1,275

The profit = $1,275 - $5,100 = -$3,825 = ($3,825)

2) The number of Newly Opened Accounts = 0.25 which gives, that Gustin has to conduct 4 seminars to be sure of 1 new account, which represents a probabilistic variable which is the definition of a continuous random variable.

Therefore, the number of new accounts is a continuous random variable.

Answer:

h= 2v / πr²

Step-by-step explanation:

height of a cone is twice of it's volume divided by π and square of radius

Step-by-step explanation:

v = 1/2 πr²h

v / 1/2 πr² = 1/2 πr²h / 1/2 πr² (Divide both sides of the equation by 1/2 πr² to find the formula for height (h).

v / 1/2 πr² = h or h = 2v / πr²

Answer:

both

Step-by-step explanation:

hi! let's plug in the ordered pairs into the equation. the x-coordinate is substituted for x in the equation, while the y-coordinate is substituted for y.

y≥-2x+4

(0,4)

4≥-2(0)+4

4≥0+4

4≥4

this is correct since 4 is equal to 4.

(-1,8)

8≥-2(-1)+4

8≥2+4

8≥6

this is also correct since 6 is less than 8.

therefore, both ordered pairs are solutions of the inequality.

Answer:

The answer is Beth.

Step-by-step explanation:

It states "Becky is not Sleeping Beauty and went trick-or-treating with Snow White" so we know that its not Becky. It also states "Beth and Sleeping Beauty are sisters" so we know that Beth is not Sleeping Beauty and we know that Becky is not Sleeping Beauty or Snow White. So it means that Barbara is Sleeping Beauty, Becky is Cinderella and Beth is Snow White.
