A bottle containing 64 fluid ounces of juice cost $3.84 what is the unit rate

Answers

$0.06 for one fluid ounce would make the most sense here. hope i helped. 

Answer: $0.06

Step-by-step explanation:

Given : A bottle containing 64 fluid ounces of juice cost $3.84.

i.e. The cost of 64 fluid ounces of juice= $3.84

To find the unit rate , we apply unitary method.

The cost of one fluid ounces of juice = Cost of 64 fluid ounces divided by 64

= $3.84 ÷  64

= $0.06

Therefore ,  we get

The cost of one fluid ounces of juice= $0.06

Hence, the unit rate = $0.06

How many solutions does this equation have: -9x+1=-9x+1

Answers

Final answer:

The equation -9x+1=-9x+1 has infinitely many solutions.

Explanation:

This equation, -9x+1=-9x+1, is an example of an equation with infinitely many solutions. This means that any value of x will satisfy the equation. To see this, we can simplify the equation:

-9x + 1 = -9x + 1

By subtracting -9x from both sides, we get:

1 = 1

This is a true statement, which means that any value of x is a solution to the equation. Therefore, there are infinitely many solutions to this equation.

What is 499 divided by 2? And show steps too

Answers

The answer would be 249 with a remainder of 1

You would first put the 2 over the 4, as 2 times 2 is 4. Bring the 9 down. 2 goes into 9 about 4 times, but it has the remainder of 1. You bring the other 9 down, and now it says 19. 2 x 9 equals 18, so you put the 9 on top and there you have 249 with the remainder of 1. 
Hey there! Hello!

So, when dividing by two, any odd number you're given will not divide wholly and will always have a remainder of one. When you say to show steps, I assume that you mean to show the long division process of the problem, which I have attached to my answer. 

The final answer is 249 with a remainder of one. If you need that as a decimal, it'll be 249.5.

You put $500 in your bank account. With an interest rate of 5%, how long will it take the account to reach $600? Use the formula: I = Prt.

Answers

4 years

5% of 500 is 25 and that goes into it 100 4 times
 so the answer is 4 years

Final answer:

To calculate how long it will take for a bank account with an initial deposit of $500 to reach $600 at a 5% simple interest rate, you first determine the total interest required ($100), then use the formula I = Prt to solve for time. The calculation shows that it will take 4 years for the account to reach $600.

Explanation:

To determine how long it will take for an account to reach $600 with an initial deposit of $500 at a simple interest rate of 5%, we can use the simple interest formula I = Prt, where I is the interest, P is the principal amount, r is the rate, and t is the time in years.

First, we calculate the total interest needed for the account to reach $600:

Total amount desired = $600Principal (initial amount) = $500Interest needed = Total amount - PrincipalInterest needed = $600 - $500 = $100

Next, we use the formula I = Prt to solve for time (t):

I = $100P = $500r = 0.05 (5% expressed as a decimal)$100 = $500 × 0.05 × t$100 = $25tt = $100 / $25t = 4 years

Therefore, it will take 4 years for the account to reach $600.

You float 2000 feet along a lazy river water ride. The ride takes less than 10 minutes. Give two examples of possible times and speeds.

Answers

200 ft/m or every minute there is 200 ft traveled.

Answer:

The speed can be expressed like less than 200 feet per minutes.The speed would be 222.22 feet per minute or less.

Step-by-step explanation:

We know that the distance traveled is

[tex]d=2000ft[/tex]

The time that took to travel this distance is

[tex]t<10min[/tex]

This means that the time could be 9 minutes, 8 minutes, 7 minutes. It can be a number between 0 and 10.

The speed is defined as

[tex]s=\frac{d}{t}[/tex]

Replacing all values, we have

[tex]s=\frac{2000ft}{10min}= 200 ft/min[/tex]

Therefore, the speed can be expressed like less than 200 feet per minutes.

Another possible example is using a time of 9 minutes

[tex]s=\frac{2000ft}{9min}= 222.22 ft/min[/tex]

In this case, the speed would be 222.22 feet per minute or less. Notice that this time the speed is not "less than", we have to include a equality relation, because we already used a time that's inside the interval of time given by the problem.

Does anyone know how to solve by substitution for 1/2x+7=y and 3y-11=-x

Answers

Substitution isn't too difficult to grasp. What you must first come to understand is that in both equations (in this particular problem) x and y are assumed to be the same numbers respectively. Meaning if you looked at the x value of the function: (Keep in mind [tex] \frac{x}{2} [/tex] is the same as [tex] \frac{1}{2} x[/tex])
[tex] y= \frac{x}{2} + 7 [/tex]

It would be the same as the x value in the function: 
[tex]-x = 3y - 11[/tex]

Due to having too many variables we can't solve for a specific variable with the equations in there current form, but because they have equal values of x and y we can solve for x or y and SUBSTITUTE that value for x or y into the other equation! By doing so we eliminate a variable and make it possible to solve that equation for one of the two variables. Luckily they already solved the equations for y in the first one (Keep in mind x, and -x are not the same, thus if you want to use the -x equation you'll need to multiply all numbers by -1.

Explanation aside, let's get to the problem!
 [tex] y= \frac{x}{2} + 7 [/tex]

Now we take that value for y, and substitute it in the other equation wherever there is a y.

[tex]-x = 3[tex]( \frac{x}{2}+7)[/tex]- 11[/tex]

Distribute the 3 to all terms in the parenthesis. (Remember only multiply the numerator by 3! (don't multiply the denominator by 3 is what I'm trying to say)... also if you have forgotten.. the numerator is the top of the fraction and the denominator is the bottom!)

[tex]-x= \frac{3x}{2}+21 - 11 [/tex]

Subtract 11 from 21. 

[tex]-x= \frac{3x}{2}+10[/tex]

Subtract 10 on both sides. 

[tex]-10-x= \frac{3x}{2}+10-10[/tex]

Simplify the right side (10-10 = 0) and add x on both sides!!

[tex]-10 = \frac{3x}{2} +x[/tex]

Add the x's together. To do this gain a common denominator by multiplying the +x by 2/2. Then add it together!

[tex]-10 = \frac{5x}{2} [/tex]

To get x alone we need to remove the fraction. To do that multiply by the fractions reciprocal (flip the fraction and multiply both sides by it. Keep in mind you do not want to multiply by x in this case[tex] \frac{2}{5}*-10 = \frac{5x}{2} * \frac{2}{5} [/tex])

Cancel out the fraction on the right side, and multiply the -10 by 2/5. [tex] \frac{-20}{5} = x[/tex]
x = -4

You probably are thinking... wow that's a lot of work! Well you are somewhat right, but luckily the next part is pretty easy. Pick one of the equations, and plug in the value you got for x and solve for the other variable (y). I'm going to choose the one with y already solved for. 

[tex] \frac{-4}{2} + 7 = y [/tex]
[tex]y = -2 + 7 [/tex]
[tex]y = 5[/tex]

So our answers are: 
x = -4
y = 5

A line goes through the point (5,-7) and has a slope m= -3. Write the equation that represents the line (show work).

Answers

Using point slope formula, y- y1 = m(x - x2)
y - -7 = -3( x - 5)
y + 7 = -3(x - 5)

If the answer needs to be in slope intercept form multiply the -3 by x and -5

y + 7 = -3x +15
Subtract 7 from both sides
y = -3x + 8

The equation that represents the line y = -3x + 8

The slope intercept equation is represented as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

m = -3

y = -3x + b

using (5,-7)

-7 = -3(5) + b

-7 = -15 + b

b = -7 + 15

b = 8

Therefore,

y = -3x + 8

On Wednesday, Abby and Lauren could not practice together, so they practiced separately. Abby practiced for 11/12 of an hour and Lauren practiced for 2/3 of an hour. How long did they practice on Wednesday?

Answers

Abby practiced for 55 minutes (60 minutes/12 and *11), Lauren practiced for 40 minutes (60/3 and *2)

Final answer:

Abby and Lauren practiced for a total of approximately 1.58 hours on Wednesday.

Explanation:

The subject of this question is Mathematics and it concerns the addition of fractions. It is aimed at Middle School grade level.

Abby practiced for 11/12 of an hour and Lauren practiced for 2/3 of an hour, and to find out how long they both practiced, we need to add these two fractions together. Converting these fractions into like fractions (with same denominator), we have Abby's time as 33/36 (since 11/12 = 33/36) and Lauren's time as 24/36 (since 2/3 = 24/36).

Adding together Abby's practice time (33/36) and Lauren's practice time (24/36), gives 57/36 or 1 21/36 hours which is approximately 1.58 hours.

Answer is false.

Answer: The given statement is FALSE.

Step-by-step explanation:  We are given to check whether the following statement is True of False :

"The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x".

We will be using the following distributive property :

Niall owes $187 to his cousin. However, he doesn't have any money right now. He hopes to earn some money by painting a house. He gets paid $34 for every 2 hours he paints. Which equation of a line models y, the amount of money he will have after paying back his cousin, in terms of x, the number of hours he spends painting?

Answers

The equation you would write would be:
2x+34=187

Answer:

[tex]y=17x-187[/tex] where x>11

Step-by-step explanation:

Niall gets $34 for 2 hours.

So, he gets [tex]34/2=17[/tex] dollars per hour.

Now, he owes $187 to his cousin.

Let the number of hours he works be = x

Let the money left with him after paying his cousin be = y

So, the equation forms:

[tex]y=17x-187[/tex]

Rather we can say it is :

[tex]y=17x-187[/tex] where x>11

If we want to know how many hours are needed to pay the debt, we can consider y = 0

[tex]17x-187=0[/tex]

[tex]17x=187[/tex]

[tex]x=187/17[/tex]

So, x = 11 hours

So, Niall needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

Kenny reads 3/8 page in 2/5 minute what is kennys unit rate

Answers

it is 31/40 i got that i hope you make a hundred on your test i hope that is the right answer i not really good at math 

Kenny's unit rate of reading is 15/16 page per minute, which is determined by dividing the number of pages he reads by the time taken and then calculating the equivalent for one minute.

Kenny reads 3/8 page in 2/5 minute. To find Kenny's unit rate, we calculate how many pages he would read in one minute.

To find the unit rate, you divide the number of pages by the number of minutes:

(3/8) page / (2/5) minute

= (3/8) \/ (2/5)

= (3/8) \/ (5/2) [Because dividing by a fraction is the same as multiplying by its reciprocal]

= (3/8) * (5/2)

= (3*5) / (8*2)

= 15/16

So, Kenny's unit rate is 15/16 page per minute.
