Answer:

[tex]160\ \text{s}[/tex]

Step-by-step explanation:

The inequality that represents the situation is

[tex]500-2.5t<100[/tex] where [tex]t[/tex] is the time in seconds

[tex]\Rightarrow -2.5t<100-500[/tex]

[tex]\Rightarrow -2.5t<-400[/tex]

[tex]\Rightarrow 2.5t>400[/tex]

[tex]\Rightarrow t>\dfrac{400}{2.5}[/tex]

[tex]\Rightarrow t>160\ \text{s}[/tex]

So, the time after which there will be less than 100 gallons of water is [tex]160\ \text{s}[/tex].

Answer:

(- 2, 3 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 1 → (1)

x - 3y = - 11 → (2)

Adding the 2 equations term by term will eliminate the y- term

5x + 0 = - 10

5x = - 10 ( divide both sides by 5 )

x = - 2

Substitute x = - 2 into either of the 2 equations and solve for y

Substituting into (1)

4(- 2) + 3y = 1

- 8 + 3y = 1 ( add 8 to both sides )

3y = 9 ( divide both sides by 3 )

y = 3

solution is (2, - 3 )

Answer:

x=-2, y=3

Step-by-step explanation:

4x + 3y = 1.......... Equ 1

x - 3y = -11...........Equ 2

5x=-10

x=-2

From equ 1

4x + 3y =1

4(-2)+3y=1

-8+3y=1

3y=1+8

3y=9

y=3

Answer:

Step-by-step explanation:

W=2.5, L=x

A=LW=2.5x

P=2(L+W)=2(2.5+x)=5+2x

P=A

5+2x=2.5x

5-0.5x=0

-0.5x=-5

x=10

Notice that y = 2x, which means you can replace any y and turn them into 2x

x = -y + 6

x = -(2x) + 6

Move the x terms to the left and change the sign

x + 2x = 6

3x = 6

x = 2

Now that you know x, substitute them back into the first y = 2x

y = 2(2)

y = 4

Answer: x = 2, y = 4

-2(x+12)

Step-by-step explanation:

Answer:

1 button.

Step-by-step explanation:

Total buttons = 40

Total red buttons = 6

Total Buttons removed =25

Buttons left = 40–25 = 15

Let the red buttons left = x

1.)Then, the probability of red buttons after removing 25 buttons = x/15 outcome / Total outcome)

2.)Probability of red buttons in the bag after removing 25 buttons is 1/3 (As given in the question)

Comparing Statement 1.) & 2.) , We get

x/15 = 1/3

x = 5

So the red buttons left = 5

Total red buttons= 6

Red buttons removed = 6–5= 1

Hence, only 1 button was red in the 25 removed buttons

There is only one red button in the removed buttons if it has a chance of drawing a red button from the bag after removing 25 buttons from the bag with 14 blue, 6 red, 12 green, and 8 purple buttons is 1/3. This is obtained by equating the probability of getting red buttons from the bag after removing 25 buttons with the given probability of red buttons.

Probability is the measure of the likelihood of an event occurring.

Probability is given by the ratio of the number of favorable outcomes with respect to an event to the total number of possible outcomes.

[tex]p(A) = \frac{n(A)}{n(S)}[/tex]

p(A) is the probability of event A

n(A) is the number of outcomes with respect to A

n(S) is the total number of possible outcomes

Given that a bag contains 14 blue, 6 red, 12 green, and 8 purple buttons.

So the total number of buttons in the bag = 40

It is given that 25 buttons are removed from the bag randomly

thus, the remaining buttons in the bag = 40 - 25 = 15

It is given that the probability of drawing a red button from the bag after removing 25 buttons is 1/3

So, for finding the number of red buttons in the bag after removing we can write,

n(A) = p(A) × n(S)

here, A is the event of drawing the number of red buttons and p(A) = 1/3 and  n(s) = 15 (after removing)

Thus, the number of red buttons in the bag after removing = [tex]\frac{1}{3}[/tex] × 15 = 5

So, the number of red buttons left in the bag = 5

then, the red buttons removed from the bag = 6 - 5 = 1

Therefore, only 1 red button is removed from the bag.

Answer:

5/10, 1/2, 50% and 0.5 are all correct answers in different forms.

Step-by-step explanation:

5 of the balls are basketballs or soccer balls. This is 5/10 of the balls.

Remember that the standard form of a line equation is y = mx + b.   Since you need a line that is parallel to y = 5x - 2, the first thing to do is use the same slope (m), which is 5 in this case.

The new line would look like this:  y = 5x + b.  I use "b" instead of -2, since we'll calculate a "b" for the new line by substituting the given point of (2, -1) into y = 5x + b.

 -1 = 5*(2) + b

 b = -11  

The parallel line that goes through (2,-1) is y = 5x - 11

The new line is the blue, on the right.  Note that it is parallel to the original (green) line and also intersects at  (2, -1).  (Each chart is is 0.5 unit).

My dear friend Ankush,

How are you? I hope everything is going well and you are fine. I am also fine and doing okay.

I am writing to you in response to your last letter. You asked me which subject I love the most and unlike you, I am no math wizard. But I do love literature, so we are poles apart. All jokes aside, I love literature as it is a way for me to be transported to a whole different world and it gives me the space to enjoy. Just like you love math, I also love books, stories, and all the like. It is a form of escape for me and it has become more of an obsession than mere interest.

Anyway, books provide me a sense of being in my own world, where I can meet different people and be transported to different periods in history. This is my way of being involved and learning about the cultures of the world.

I hope I didn't make you bored. But as you used to say, we all have our likes and dislikes, but that's what makes us who we are.

Please come visit me whenever you have a holiday. Hoping to see you soon.

Take care.

Your best friend,

Rahul.

Substitute for the n for n=1,2,3,4 so the first term is 57-4(1-1) so =57-4(0) so

a(1) = 57-0 = 57  so that is the 1st term

2nd term 57-4(2-1) so =57-4(1) so   a(2) = 57-4 = 53, etc.
