An outdoor spigot at the school has a leak and is dripping water. A student counted eighty drops of water in five minutes and noticed that sixty drops of water filled a container to a level of ten milliliters. If the spigot is not fixed and this dripping rate continues, how many liters of water will be wasted in four weeks? Round the answer to the nearest liter.

Answers

Answer 1

Answer:

108 liters

Step-by-step explanation:

Given that:

80 drops are there in 5 minutes.

Time to be considered is 4 weeks.

Let us find number drops in 4 weeks.

Number of drops in 5 minutes = 80

Number of drops in 1 minute = [tex]\frac{80}{5}[/tex]

Number of drops in 60 minutes = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex]

Number of drops in 24 hours (60 [tex]\times[/tex] 24 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex]

Number of drops in 28 days (28 [tex]\times[/tex]24 hours OR 60 [tex]\times[/tex] 24 [tex]\times[/tex]28 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex][tex]\times[/tex]28 = 645120

Now, we are given that 60 drops = 10 mL

1 drop = [tex]\frac{10}{60}[/tex] mL

645120 drops = [tex]\frac{10}{60} \times 645120[/tex] =  107520 mL

We know that 1000 mL = 1 Liter

1 mL =  [tex]\frac{1}{1000}[/tex] Liter

107520 mL = [tex]\frac{1}{1000} \times 107520\ L \approx 108\ L[/tex]

So, the answer is 108 Liter.

A city park is opening a new swimming pool. You can pay a daily entrance fee of $3 or purchase a membership for the 12 week summer season for $82 dollars and pay only $1 per day to swim. How many days would you have to swim to make the membership worthwhile?

Answers

Answer:

41 days

Step-by-step explanation:

The membership would be worthwile if you swim an amount of days paying the daily entrance fee that would make your total cost equal to the cost of the membership. From that you can write the following expression:

3x=82+(1*x), x is the number of days you go to swim

Now, you can solve for x:

3x=82+x

3x-x=82

2x=82

x=82/2

x=41

According to this, the answer is that you would have to swim 41 days to make the membership worthwile.

Martin has 5/6 of a pizza . Liam has 4 times as much pizza as Martin. How much pizza does Liam has?

Answers

Answer:

10/3 pizza

Step-by-step explanation:

step one:

This problem is focused on ratios and fractions

from the problem statement, Martin has 5/6 pizza

Liam has 4 times more of what Martin have

step two:

so we can express what Liam has as

=(5/6)*4 = 20/6or

=5/6+5/6+5/6+5/6= 20/6

= 20/6

step three:

we can reduce both numerator and denominator

= 10/3

Hence Liam has 10/3 pizza

Quantity of pizza that Liam has is;

3 full pizzas and a third of a pizza.

Martin has 5/6 of a pizza.

Thus;

Quantity of pizza that Martin has = 5/6

Now we are told that Liam has 4 times as much as Liam, then;

Quantity of pizza Liam has = 4(5/6) = 10/3

This translates to 3⅓ pizza

Thus, in conclusion, Liam has 3 full pizzas and a third of a pizza.

Chloe spent $69 and now has no money left. She had before her purchase. She had $ before her purchase. can you please help me with this please​

Answers

Answer:

$69

Step-by-step explanation:

Given

[tex]Purchase = \$69[/tex]

[tex]Amount\ Left = \$0[/tex]

Required

Determine the cash before purchase

To get the her amount before the purchase, we simply add both given parameters together.

This is done as follows;

[tex]Amount = Amount Left + Purchase[/tex]

Substitute 0 for Amount Left and 60 for Purchase

[tex]Amount = \$0 + \$69[/tex]

[tex]Amount = \$69[/tex]

Hence, she had $69 before the purchase

Point a is at (-1,-9) and point m is at (0.5,-2.5) point m is the midpoint of a and point b what coordinates of point b

Answers

Answer:

B (2, 4)

Step-by-step explanation:

A (-1,-9); M (0.5, -2.5); B (xB, yB)

M is the midpoint of AB, therefore we have these 2 equations:

(*) xA + xB = 2. xM

(**) yA + yB = 2. yM

(*) <=> xB = 2. xM - xA = 2x0.5 - (-1) = 1 + 1 = 2

(**) <=> yB = 2. yM - yA = 2x(-2.5) - (-9) = -5 + 9 = 4

So, B (2, 4)

Let’s call the sides N, E, S, W as in the direction each side is facing like a compass. Side N would be 10in+5in=15in. Side E would be 4in+6in=10in. Side S would be 10in+5in=15. Side W would be 4in+6in=10in. Then you add all four sides together: 15in+10in+15in+10in=50in. Your final answer is: the perimeter is 50inches.

Answer:

50in

Step-by-step explanation:

Look at the picture.

We move both short sides to form a rectangle.

The formula of a perimeter of a rectangle:

P = 2(l + w)

l - length

w - width

We have l = 15in and w = 10in.

Substitute:

P = 2(15in + 10in) = 2(25in) = 50in

There are 67 electricians on a jobsite. Thirty-one (31) are "career" helpers. Twenty-four (24) are indentured apprentices. Nine (9) are journeymen. Three (3) are foremen. What percentage of the electricians are indentured apprentices?

Answers

Answer:

35.82 %

Step-by-step explanation:

Total no of electrician job = 67

No. of indentured apprentices = 24

____________________________________

Percentage mean per hundred,

Example for x percentage of any thing

literally it means if there are total no. of 100 things, then x  is the number of thing  in consideration.

Formula for  percentage calculation = (number of a particular thing/ total no of things out of which  the particular thing is considered) *100

______________________________________

Here,

Total no of electrician job = 67

No. of indentured apprentices = 24

percentage of  indentured apprentices = (Total no of electrician job /No. of indentured apprentices)   * 100 = 24/67 *100 = 35.82 %

Thus, there  35.82 % indentured apprentices  out of total electricians.

It means that if there were 100 electricians, then there would have been 35.82  indentured apprentices out of those 100 electricians.

What value of x makes this equation true? 2x + 3 = 9

Answers

Answer:

the is x would equal to 3

Answer:

[tex]\boxed {\tt x=3}[/tex]

Step-by-step explanation:

We want to solve for x, therefore we must isolate the variable.

We are given the equation:

[tex]2x+3=9[/tex]

3 is being added to 2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.

[tex]2x+3-3=9-3[/tex]

[tex]2x=9-3[/tex]

[tex]2x=6[/tex]

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

[tex]\frac{2x}{2} =\frac{6}{2}[/tex]

[tex]x=\frac{6}{2}[/tex]

[tex]x=3[/tex]

Let's check our solution. Plug 3 in for x and solve.

[tex]2x+3=9[/tex]

[tex]2(3)+3=9[/tex]

[tex]6+3=9[/tex]

[tex]9=9[/tex]

This checks out, so we know our solution is correct.

The solution to the equation 2x+3=9 is x=3
