A leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. After the leak is fixed, the height of the water is 4.75 feet. The equation 4.75 = x + (negative 0.25) can be used to find x, the original height of the water in a pool.

What was the original height of the water in the pool in feet?

Answers

Answer:

Assuming the leak took 2 hours to fix, the original height of the pool is 5 feet.

Step-by-step explanation:

This is probably the most simple "high school" problem I've seen in a while. All you have to do is move the negative 0.25 to the other side to isolate x. That gives you 4.75 + 0.25, or 5 feet.

The original height of the water in the pool was 5 feet.

Given that there is leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours.

After the leak is fixed, the height of the water is 4.75 feet.

The equation 4.75 = x - 0.25 can be used to find x, the original height of the water in a pool.

we need to find the original height of water,

To find the original height of the water in the pool, we can use the given information and equation.

Let's break down the equation: 4.75 = x - 0.25

Here, x represents the original height of the water in the pool, and -0.25 represents the decrease caused by the leak.

The equation states that after the leak is fixed, the height of the water in the pool is 4.75 feet. This means that the final height (4.75 feet) is equal to the original height (x) minus the decrease caused by the leak (-0.25 feet).

To solve for x, we can isolate it on one side of the equation.

Adding 0.25 to both sides of the equation, we get:

4.75 + 0.25 = x - 0.25 + 0.25

Simplifying the equation, we have:

5 = x

Therefore, the original height of the water in the pool was 5 feet.

Amy has $50 in her lunch account. Amy spends $3 a day for lunch. Amy's mother receives a notification when Amy's
account balance reaches $5 or lower. How many lunches can Amy purchase until her mother receives a notification? And what is the equation in slope intercept form

Answers

Answer:

Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.

Step-by-step explanation:

The balance Amy has in her lunch account is a function of the number of lunches she has consumed.

The initial balance is $50 and it decreases by $3 for every lunch Amy has. Thus, the function that models the balance in her lunch account is:

[tex]B(x)=50-3x[/tex]

Where x is the number of lunches.

Her mother receives a notification when the balance goes at $5 or lower, thus the condition that triggers the notification is:

[tex]B(x) \le 5[/tex]

Or, equivalently:

[tex]50-3x\le 5[/tex]

Subtracting 50:

[tex]-3x\le 5-50[/tex]

[tex]-3x\le -45[/tex]

Multiplying by -1 (and flipping the sign):

[tex]3x\ge 45[/tex]

Solving:

[tex]x\ge45/3[/tex]

[tex]x\ge 15[/tex]

Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.

24. Janet and Jack are walking in a two-day event to raise money for charity.
Janet asks a friend for a $7.50 donation, plus $0.10 for each mile she
walks. Jack asks a friend for a $5.50 donation, plus $0.15 for each mile
he walks. At how many miles of walking would Janet and Jack collect the
same amount of money?

Answers

Answer:

40 miles walk

Step-by-step explanation:

Let the miles walked by both of them be x at which money collected by same

for Janet

Fixed donation  asked = $7.50

money asked for walking 1 mile = $0.10

money made by Janet if he walks x miles = x*$0.10 = $0.10x

Total money collected by Janet = Fixed donation  asked + money made by Janet if he walks x miles

Total money collected by Janet =7.50 + 0.10x

For Jack

Fixed donation  asked = $5.50

money asked for walking 1 mile = $0.15

money made by Janet if he walks x miles = x*$0.15 = $0.15x

Total money collected by Jack = Fixed donation  asked + money made by Jack if he walks x miles

Total money collected by Jack =5.50 + 0.15x

we have to find miles at which money collected by both of them be same

and we have decided that it it as x mile walk then

Total money collected by Janet = Total money collected by Jack

7.50 + 0.10x = 5.50 + 0.15x

=> 7.50 - 5.50 = 0.15x - 0.10x

=> 2 = 0.05x

=> x = 2/0.05 = 40

Thus, at 40 miles walk money collected by both of them will be same

Answer:If the question is asking for 9/10/3/5 the answer is 3/50; however, if the question is asking for (9/10) / (3/5), the answer should be 3/2.

Step-by-step explanation: The 3/50 answer comes from 9/10 which equals .9, dividing that by 3. That equates to .3, and then dividing by 5 which measures up to .06. From there you can turn .06 into a fraction being 3/50.

You get the 3/2 by dividing (9/10) by (3/5). .9/.6 is 1.5. When converted to a fraction 1.5=3/2. Hope this could help.

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9

Answers

Given:

Different equations are given.

Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.

To find:

The equation which gives a different value of x than the other three.

To find the equations that could you use to find the price of one tire patch.

Solution:

In option A,

[tex]9.1 = -0.2x + 10[/tex]

[tex]0.2x= 10-9.1[/tex]

[tex]0.2x= 0.9[/tex]

Divide both sides by 0.2.

[tex]x=\dfrac{0.9}{0.2}[/tex]

[tex]x=4.5[/tex]

Similarly,

In option B,

[tex]10 = 9.1 + 0.2x[/tex]

[tex]0.9= 0.2x[/tex]

[tex]4.5=x[/tex]

In option C,

[tex]10-0.2x = 9.1[/tex]

[tex]-0.2x = -0.9[/tex]

[tex]x = 4.5[/tex]

In option D,

[tex]9.1 – 10 = 0.2x[/tex]

[tex]-0.9 = 0.2x[/tex]

[tex]-4.5 = x[/tex]

Since option D has difference solution, therefore the correct option is D.

Let price of one tire patch be x.

So, price of 4 tire patches = 4x

Remaining amount in Rhyan's gift card = $1.90

Total amount = $22.20

Price of 4 tire patches + Remaining amount in gift card = Total amount

[tex]4x+1.9=22.2[/tex]

It can be written as

[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]

Therefore, the correct options are C and E.
