Each minute, a faucet allows 4/9 gallons of water to enter a large tub, and the drain allows 8/9 gallons to leave the tub.
What is the change in the amount of liquid in the tub after 1/3 minute?
Enter your answer as a fraction in lowest terms in the box
Answer:
Step-by-step explanation:
The amount of water in the bathtub per minute:4/9-8/9=-4/9;
liquid after:1/3* (-4/9)=-4/27
If the change in the amount of liquid in the tub for 1 minute is 4/9, The change in the amount of liquid in the tub after 1/3 minute will be 4/27.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that, Each minute, a faucet allows 4/9 gallons of water to enter a large tub, and the drain allows 8/9 gallons to leave the tub.
The rate of net flow of the water = Water outgoing - Water ingoing
The rate of net flow of the water = 8/9 - 4/9
The rate of net flow of the water =4/9
The change in the amount of liquid in the tub after 1/3 minute is,
=4/9 × 1/3
=4/27
Thus, if the change in the amount of liquid in the tub for 1 minute is 4/9, The change in the amount of liquid in the tub after 1/3 minute will be 4/27.

Steps for 4-6h-8h=60
Answer:
To solve for h, isolate the “h” on one side of the equation.
Combine like terms on the left sides (h). When combing like terms add and subtract as normal and attach the variable.
4-14h=60
Subtract 4 from both sides.
-14h=56
Divide both sides by -14.
h=-4
Hope this helps! :)
Answer:
h = -4.
Step-by-step explanation:
4-6h-8h=60
4-4-6h-8h = 60-4
-14h = 56
h = 56/-14
= -4.

Four boys weighed themselves in different pairs and alone. The weights of the pairs were 110 kg, 112 kg, 113 kg, 118 kg, 121 kg, and the weight of one pair was lost. The total weight of the four boys was 230 kg. What was the lost weight?
The lost pair of weight can be found by subtracting the a known pair from
the total weight leaving the value of the lost pair.
The lost weight of a pair of boys is 120 kg
Reasons:
Let a, b, c, and d represent the weights of the four boys, we have;
The number of ways of selecting pairs (two boys) of boys from a group of
four is given using combination formula as follows;
[tex]_nC_r = \dfrac{n!}{r! \cdot (n - r)!}[/tex]
Which gives;
[tex]_4C_2 = \dfrac{4!}{2! \cdot (4 - 2)!} = 6[/tex]
₄C₂ = 6
Therefore, the weights of the pairs are;
a + b = 110
a + c = 112
a + d = 113
b + c = 118
b + d = 121
c + d = Lost weight
c + d = Lost weighta + b + c + d = 230 (given)
Therefore;
The lost weight, c + d = 230 - (a + b)
Which gives;
c + d = 230 - (110) = 120
The lost weight = c + d = 120
The lost weight = 120 kgLearn more here:

Answer:
116
Step-by-step explanation:
you can use variables
a+b=110
a+c=112
a+d=113
b+c=118
b+d=121
add up the weights and you get 574 kg (you need to find c+d)
3a+3b+2c+2d=574
a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3
you are left with c+d=116

if i roll a dice 120 times how many times am I gonna get 4
Answer:
20 out of 120 times
Step-by-step explanation:
As others have said, the general formula is:
expected successes = probability*number of trials
Perhaps an easier question: If you roll a die 6 times, how many 4s would you expect to get?
1, right? 1 out of every 6. That’s what 1/6 means.
If you roll a die 12 times, you expect 2. 2/12 = 1/6

The circumference of a circle is 12 pi what is the diameter
Answer:
Step-by-step explanation:
Givens
C = 12 * pi
C = 2*pi * r
Solution
2*pi * r = 12*pi Divide both sides by 2pi
2*pi * r/ 2*pi = 12*pi/2pi
r = 6
Answer: the diameter = 2 * r
the diameter = 12
Bob's car can go
111 miles on tank
of gas. How far can it
go on a full tank?
PLEASE HURRY
Answer:
296 miles
Step-by-step explanation:
Use a proportion:
111/( 3/8) = x/ 1
Cross Multiply
(3/8)x = 111
Multiply both sides by 8/3 ; reciprocal
x = (8/3) (111)
x = 296 miles
solve for x, 500 = 50*(1.23)^x
this is for an exponential functions task where 500 represents an animal population, 1.23 is the growth rate and 50 in the initial population.

This is a graphing problem and I am trying to find the x-intercepts and the y-intercepts. Please show me the full steps. I really appreciate it thank you.
Answer:
Step-by-step explanation:
the x intercept occurs when y=0
[tex]0=\frac{2x+6}{x-1}\\0=2x+6\\x=-3\\(-3,0)[/tex]
The y intercept occurs when x=0
[tex]y=\frac{2(0)+6}{0-1}=-6\\(0,-6)[/tex]
Answer:
Below in bold.
Step-by-step explanation:
To find the x -intercept put f(x) = 0:
(2x - 6)/(x - 1) = 0
2x - 6 = 0
2x = 6
x = 3
So the x-intercept is at the point(3, 0).
To find the y-intercept put x = 0:
y = (2(0) - 6)/(0 - 1)
= -6/-1
= 6
So the x-intercept is at the point(0, 6).
How do you find the percentage off of a price
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Step-by-step explanation:
Example:
Find the original price (for example $90)Get the the discount percentage (for example 20%)Calculate the savings: 20% of $90 = $18Subtract the savings from the original price to get the sale price: $90 - $18 = $72You're all set!Discount formula:
(original_price * discount / 100)
_____________________________________________________
Percentage discount is a discount that is given to a product or service that is given as an amount per hundred. For example, a percentage discount of 20% would mean that an item that originally cost $100 would now cost $80. This is common with promotional and seasonal sales, as a way of encouraging consumers to buy an item at a reduced cost.
___________________________________________________
$279 - $55.80 = $223.20
You would therefore be saving $55.80 on the purchase for a final price of $223.20.
For this calculator, a "stackable additional discount" means getting a further percent off of a product after a discount is applied. Using the same example, assume that the 20% discount is a discount applied by the store to the product. If you have a coupon for another 15% off, the 15% off would then be applied to the discounted price of $223.20. It is not a total of 35% off of the original price. It is less:
15% of $223.20 = $33.48
$223.20 - $33.48 = $189.72
Thus, with a 20% discount off of $279, and an additional 15% off of that discounted price, you would end up saving a total of:
$55.80 + $33.48 = $89.28
This equates to a 32% discount, rather than a 35% discount, and this calculation is how the calculator is intended to be used. As an example, to more efficiently compute the discount described above:
Final price = (0.80 × 279) × 0.85 = $189.72
This is because 80% of the original price is the same as subtracting 20% of the original price from the original price. The same is true for 85% and 15% case applied to the discounted price.

Pete saw that he was 200 yards from shore when he dove out of the boat. It took him 49 seconds to swim the first 50 yards. At that rate, how much longer will it take to reach the shore?
tysm<3
Answer:
147 seconds to get to the shore(after the 49 seconds)
Step-by-step explanation:
If Pete swam at a constant speed of 50 yards/49 seconds, you just have to multiply that by four, to get 200 yards. If you want the total time from his boat to shore, that is 196. If you want how much longer it would be, it would be 147 seconds

Answer:

Step-by-step explanation:
Since both numbers are being multiplied by 10^-5, we can completely cut that part out of the inequality and instead just compare the values 3.2 and 4.6. It is obvious when looking at the problem that 3.2 is smaller than 4.6, so we will use the less than symbol <.

{4z=8}
{3x-2z=11}
{x-4y+z=11}
Step-by-step explanation:
4z = 8
z = 8/4
z = 2
3x - 2z = 11
3x - 2.2 = 11
3x - 4 = 11
3x = 11 + 4
3x = 15
x = 15/3
x = 5
x - 4y + z = 11
5 - 4y + 2 = 11
-4y = 11 - 5 - 2
-4y = 4
y = 4/-4
y = -1
Solution → {x,y,z} = {5,-1,2}
