Water is a valuable resource that can easily be wasted. In this task you will
Investigate how much water the average American uses each day. You will then
Investigate how much water a family of 4 could save using different strategies,
According to some estimates, the average American uses 80-100 gallons of water
daily. Of this total, the average American uses about:
• 27% by flushing toilets
• 25% while taking showers/baths
• 10% by running the faucet while brushing teeth, washing hands, and shaving
Water is also used for various other purposes (cooking, drinking water, watering
plants, washing clothes, etc.) that account for the remaining percentage of water
used by the average American.
Table 1 shows the average amount of water used during some activities,
Table 1. Water Used by Activity and Duration

*There is no standard definition of the volume of a faucet drip, but the USGS
Water Science School uses militer (ML) as the volume of a faucet drip. So, by
these drip estimates:
• One gallon = 15,140 drips
• One liter = 4,000 drips
1)What percentage of the average American's daily water usage is
described as "various other purposes"?

Answer:

I think y=1x+2

Step-by-step explanation:

y=mx+c

m=(y2-y1)/(x2-1)

I just chose (0,2) and (-3,-1)

-1-2=-3

-3-0=-3

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

Answer:

Lacey and Rick will owe $ 7662.88  in prorated expenses

Step-by-step explanation:

The number of days till june 27 us

Jan 31 +  Feb 28   + March 31  + April 30  +  May 31  + June 26 =177 days

In a year we have 365 days

The owner has paid tax for 177 days

Now  Lacey and Rick have to pay tax for  =365 -177 days  = 188 days

Now  for one day tax amount will be

=

= 40.76

Now the tax amount for 188 days is

=

= 7662.88

Answer:

a. a*(a+b)

b. 2(a)+5

Step-by-step explanation:

Lets just say that a is your number. B was the second number in your first equation being added to a.

Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.

The restriction is that x ≠ -4 is not in the domain of the given function.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The given function is

[tex]f(x)=\frac{x-1}{x+4}[/tex]

This is not defined when the denominator is zero.

Hence the restriction is on the denominator.

This implies that

[tex]x+4 \neq 0[/tex]

[tex]x\neq-4[/tex]

The restriction is that x ≠ -4 is not in the domain of the given function.

Answer: p = 3

Step-by-step explanation:

5p - 17 = -2

Add 17 to both sides

5p = 15

Divide both sides by 5

p = 3

Answer: p=3

Step-by-step explanation:

bc you move the -17 to the right side and it becomes +17 and 17-12 is 5

so 5p=5 and divide 5 both side so you get 3

Answer:

  4.  D'(5, -5), E'(2, -7), F'(6, -1), G'(10, -8)

  5.  T(-3, 2)

Step-by-step explanation:

4. Translation by 4 units right and 5 units down adds (4, -5) to each given coordinate point. (We note that these coordinates do not actually form a parallelogram.) The figure and its translation are attached.

__

5. The translation is ...

  X' -X = (-8, -1) -(-5, -3) = (-8+5, -1+3) = (-3, 2)

The translation is left 3, up 2. We don't know the translation notation you're used to, so we'll write it as ...

  T(-3, 2) . . . . . translation left 3, up 2.

Answer:

78 inches

Step-by-step explanation:

Well if we are assuming that the 60 inches and 50 inches are straight then we can use the Pythagorean theorem to do a^2 + b^2 = c^2, so  so a=60 and b=50. so we do that we get 6100, and if we find the square root of that it will be about 78.1024, and that rounded is 78.

Answer:

[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .

Step-by-step explanation:

When  y ∝ x then,

[tex]y=k*x[/tex]

When y ∝ 1/x then

[tex]y=\frac{k}{x}[/tex]

while k is a constant.

Answer:

3/4 and 18/24; the ratios are the same.

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.
