Answer:

In a year 28743.75 gallons of water will be wasted.

Step-by-step explanation:

Given relation is -

1 gallon = 128 oz

Now, we have been given that a faucet leaks 7 oz of water per minute.

And we have 1440 minutes in a day. So, we have365\times1440=525600 minutes in a year.

Let us assume that there are 365 days in a year.

So, oz of water wasted in a year will be = 7\times525600=3679200 oz

Converting this to gallons:

\frac{3679200}{128} =28743.75 gallons

Hence, in a year 28743.75 gallons of water will be wasted.

Well, how many minutes are there in a year? It would be way too easy to  say "too many".

First, we calculate minutes in a day, which is 60 x 24 (minutes in an hour x number of hour)

This equals 1440. There are 365 days in a year, so we multiply 365 by 1440, which equals 525,600

The conversion of oz to gallon occurs, and bigger units mean division since their capacity makes the necessity for them significantly smaller; we divide 525600 by 128, and we get 4106.25.

4106.25 gallons of water are wasted in a year

Manuel is riding his bike. The graph represents the distance Manuel travels from his house over time. Describe what is happening
olasank [31]

Answer:

Manuel is moving with a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

He took rest at his destination for 4 units of time.

Then he reach his house at 5 units distance in 1 unit time.

Step-by-step explanation:

See the graph attached.

Manuel is riding his bike.

As the graph shows that Manuel starts his journey from his house and the time counts starts and then he is moving at a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

The constant speed is \frac{5}{3} units.

Then he took rest at his destination for 4 units of time.

After that, he again starts to move towards his house at a constant speed and reach his house at 5 units distance in 1 unit time.

Therefore, his speed of return is \frac{5}{1} units. (Answer)

can someone help me, Just the answer don’t worry about explaining everything, Im really bad on Math :(
Strike441 [17]

Answer:

a. -2 b. -2 c. -1 d. 4 e. -3 f. 0

Step-by-step explanation:

The average rate of change formula is:

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}

a.  

We need to find the rate of change for x = -3 to x = -2 so we look on the graph to find y.

At x = -3 it look like y = 0  so

x_{1} = -3

y_{1} = 0

At x = -2 it looks like y = 2

x_{2} = -2

y_{2} = 2

Now we can just plug everything in to the rate of change formula.

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{2- 0}{-3-(-2)} = \frac{2- 0}{-3+2} = \frac{2}{-1} = -2

So for a. our rate of chage for the given interval is -2

b.

Now that you have the formula we don't need to explain each time.

x_{1} = -2

y_{1} = 2

x_{2} = 1

y_{2} = - 4

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{-4- 2}{1-(-2)} = \frac{-4-2}{1+2} = \frac{-6}{3} = -2

c.

x_{1} = 0

y_{1} = -3

x_{2} = 1

y_{2} = - 4

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{-4-(-3)}{1-0} = \frac{-4 + 3}{1-0} = \frac{-1}{1} = -1

d.

x_{1} = 1

y_{1} = -4

x_{2} = 2

y_{2} = 0

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{0 - (-4)}{2-1} = \frac{0 + 4}{2-1} = \frac{4}{1} = 4

e.

x_{1} = -1

y_{1} = 0

x_{2} = 0

y_{2} = -3

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{-3- 0}{0-(-1)} = \frac{-3- 0}{0+1} = \frac{-3}{1} = -3

f.

x_{1} = -1

y_{1} = 0

x_{2} = 2

y_{2} = 0

\frac{y_{2}- y_{1}}{x_{2}-x_{1}}  = \frac{0- 0}{2-(-1)} = \frac{0- 0}{2+1} = \frac{0}{3} = 0

Ryan bought a total of 40 juice boxes. He bought 8 more boxes of apple juice than of grape juice. How many of each kind did he b
postnew [5]

we take away the extra 8 boxes of apple juice first:

40 - 8 = 32


Now that we have equal number of apple juice and graph juice, we divide them into 2:

32 ÷ 2 = 16


There are 16 boxes of graph juice.


We add back the 8 boxes of apple juice we took away just now

16 + 8 =24


There are 24 boxes of apple juice.


Answer: 24 boxes of apple juice and 16 boxes of graph juice.
