Answer: 3,285 Liters
Step-by-step explanation:
In the actual case, all your flushes consume 6 L of water.
You flush 4 times per day, then you consume 4 times 6 L per day, this is:
4*6L = 24 L per day.
And in one year there are 365 days, then in one year you consume:
365*24 L = 8,760 L
Now, if you upgrade the toilet, now per day you use:
one time 6 L and 3 times 3 L
Then in day, you use:
1*6 L + 3*3 L = 6L + 9L = 15L
And in the complete year, you will use 365 times that, which is:
365*15 L = 5,475 L
The amount of water that you would save is equal to the difference between the amount that you use in one year with no upgrade (8,760 L) and the amount that you would use in a year if you upgraded your toilet ( 5,475 L)
The difference is:
D = 8,760 L - 5,475 L = 3,285 L
This means that, in this situation, you would save 3,285 liters of water per year if you upgrade your toilet.
Q. Write the expanded form of h(3k-12.4).
A. 3hk-12.4h
Answer:
We conclude that:
[tex]h\left(3k-12.4\right)=3hk-12.4h[/tex]
Step-by-step explanation:
Given the expression
[tex]h\left(3k-12.4\right)[/tex]
Expanding the expression
Let us expand the expression
[tex]h\left(3k-12.4\right)[/tex]
Apply the distributive law: a (b - c) = ab - ac
here a = h, b = 3k, c = 12.4
so th expression becomes
[tex]h\left(3k-12.4\right)=h\cdot \:\:3k-h\cdot \:\:12.4[/tex]
[tex]=3hk-12.4h[/tex]
Therefore, we conclude that:
[tex]h\left(3k-12.4\right)=3hk-12.4h[/tex]

Find sin 60 degree
Answer:
sin 60° = 0.9
Step-by-step explanation:
sin 60° = cos 30°
cos 30° = 0.866025403
0.866025403 to one significant figure
0.866025403 ~ 0.9
~. means approximately.
therefore sin 60° = cos 30°
sin 60° = 0.9

A boy throws a ball into the air. The equation h=−16t^2+23t+4 models the path of the ball, where h is the height (in feet) of the ball t seconds after it is thrown. How long is the ball in the air?
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
Hence the total time it spend in the air will be 0.72secs
The total time for which the ball is in the air is 0.72 seconds and this can be determined by differentiating the given function.
Given :
A boy throws a ball into the air. The equation [tex]\rm h = -16t^2+23t+4[/tex] models the path of the ball, where h is the height (in feet) of the ball t seconds after it is thrown.
Differentiate the given function of height with respect to 't' in order to determine the value of 't'.
[tex]\rm h = -16t^2+23t+4[/tex]
[tex]\rm \dfrac{dh}{dt}=-32t+23[/tex]
Now, equate the above differential equation to zero.
-32t + 23 = 0
23 = 32t
t = 0.72 seconds
So, the total time for which the ball is in the air is 0.72 seconds.

The 12 students in the Environmental Club represent 20% of the students in the seventh grade. How many students are in the seventh grade?
The students that are in the seventh grade is 60.
How to calculate the number of students?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
Let the students that are in the seventh grade be x.
Since 12 students in the Environmental Club represent 20% of the students in the seventh grade. This will be:
20% × x = 12
0.2x = 12
Divide
x = 12 / 0.2
x = 60
Therefore, there are 60 students.

Step-by-step explanation:
Fractions are multiplied by multiplying the numerators and expressing that product over the product of the denominators:
[tex]\dfrac{a}{b}\times\dfrac{c}{d}=\dfrac{ac}{bd}[/tex]
In several cases here, the numerator product has factors in common with the denominator product. Those can be cancelled, reducing the product fraction to lowest terms.
[tex]\dfrac{3}{4}\times\dfrac{2}{3}=\dfrac{3\cdot2}{4\cdot3}=\dfrac{3\cdot2}{3\cdot2\cdot2}=\boxed{\dfrac{1}{2}}\\\\\dfrac{4}{5}\times\dfrac{3}{8}=\dfrac{4\cdot3}{5\cdot8}=\dfrac{4\cdot3}{4\cdot2\cdot5}=\boxed{\dfrac{3}{10}}\\\\\dfrac{1}{6}\times\dfrac{2}{7}=\dfrac{1\cdot2}{6\cdot7}=\dfrac{2}{2\cdot3\cdot7}=\boxed{\dfrac{1}{21}}\\\\\dfrac{4}{9}\times\dfrac{2}{3}=\dfrac{4\cdot2}{9\cdot3}=\boxed{\dfrac{8}{27}}[/tex]

Roland receives $500 as a graduation present from his aunt. He plans to use part of the money to purchase a laptop for $289, including tax. He will purchase some new video games with the remaining money. Each video game costs $52, including tax. Which inequality describes, v, the number of video games Roland can purchase with his graduation money?
Answer:
52x < $211
Step-by-step explanation:
If Roland uses $289 to purchase the laptop from the $500 that was given to him then he would be left with
500 - 289 = $211
With this he can purchase video games. Since each video game costs the same price of $52 then we can use the variable x to represent the number of games he can buy with the following inequality...
52x < $211

(where the longer it takes to solve a problem and the fewer people who answer it correctly, the more difficult it is). On each subsection, question 1 will be "easy" and question 15 will be considered "difficult." However, the ascending difficulty resets from easy to hard on the grid-ins.
Hence, multiple choice questions are arranged in increasing difficulty (questions 1 and 2 will be the easiest, questions 14 and 15 will be the hardest), but the difficulty level resets for the grid-in section (meaning questions 16 and 17 will again be "easy" and questions 19 and 20 will be very difficult).
