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.

I need help on 1-8 ..
Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
What value of x makes this equation true? 2x + 3 = 9
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

What must be added to the expression x^2 - 18x to make it a perfect square?
Answer:
+ 81
Step-by-step explanation:
Given
x² - 18x
To complete the square
add ( half the coefficient of the x- term )² to x² - 18x
x² + 2(- 9)x + (- 9)²
= x² - 18x + 81
= (x - 9)² ← perfect square

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?
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.

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
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
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)

Martin has 5/6 of a pizza . Liam has 4 times as much pizza as Martin. How much pizza does Liam has?
Answer:
10/3 pizzaStep-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.

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?
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.

Answer:
50inStep-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

Your question has been heard loud and clear.
1) (44+16)+60 * 4 -(70+16) * 0 +46 = 60+240-86 * 0 + 46 = 346
2) 79+70-(41-22) * 4-7 = 149-19 * 4 - 7 = 149-76-7= 66
3) 7 root 69 = 58.14
4) 7/14 - 1/6 + 2/8 = 1/2 - 1/6 + 1/4 = 7/12
So , 7/14-1/6+2/8 = 7/12
5th one , really I am confused bc there is nothing to solve from that equation.
