Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water.
How does Park Pool's chlorine compare to the safety standards?
Choose 1 answer:
A
Park Pool has more chlorine than the safety standards require.
B
Park Pool has less chlorine than the safety standards require.
C
Park Pool has the right amount of chlorine.
Answer:
B
Step-by-step explanation:
The requirement is 3 chlorine tablets per every 2,000 galloons of water.
The lifeguards added 8 chlorine tablets for 10,000 galloons of water.
To get from 3 tablets to 8 tablets, we multiply by 8/3.
By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.
Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.
Hey there!
The correct answer is B
If they are supposed to add 3 for every 2000, that means they should have 6 for every 4000, and 9 for every 6000, and 12 for every 8000. This means they have less.
Hope it helps and have a great day!

What is the answer to 2b + 8- 5b + 3 = -13 + 8b - 5
Answer:
2 8/11 = b
Step-by-step explanation:
2b + 8 - 5b + 3 = -13 + 8b - 5
combine like terms
11 - 3b = -18 + 8b
add 3b
11 = -18 + 11b
add 18
29 = 11b
divide by 11
2 8/11 = b

A basketball has a mass of 1 kg and is traveling 12 m/s.
What would happen to the velocity if the momentum of the basketball were cut in half?
Answer:
[tex]6\:\mathrm{m/s}[/tex] (The velocity would also be halved)
Step-by-step explanation:
The momentum of an object is given as [tex]p=mv[/tex] where [tex]m[/tex] is the mass of the object and [tex]v[/tex] is the velocity of the object.
Because mass is constant, if the momentum ([tex]p[/tex]) was cut in half, the velocity of the basketball would also be halved:
Let [tex]p_1[/tex] be the initial momentum and [tex]p_2[/tex] be the final momentum:
[tex]\frac{1}{2}p_1=p_2,\\\frac{1}{2}mv_1=mv_2, \\\fbox{$\frac{1}{2}v_1=v_2$}[/tex]
Therefore, the basketball's new velocity is [tex]\frac{1}{2}\cdot 12=\fbox{$6\:\mathrm{m/s}$}[/tex].
Which linear function has the greatest y-intercept? y = 6 x + 1 On a coordinate plane, a line goes through points (0, 2) and (5, 0). On a coordinate plane, a line goes through points (1, 2) and (0, negative 3). y = 3 x + 4.
Answer:
y = 6x + 1 (0,2) (5,0)
Step-by-step explanation:
Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.
Solve for x.
Your answer must be simplified. −30< x/-4

Yolanda’s bowling average for 2 games was 138. Her second game score was 8 points lower than her first game score. Which system of equations will determine Yolanda’s scores for her first game, f, and her second game, s?
Answer:
║⊕║Hello Wonderful Person║⊕║
This should be your answer:
So first let us solve 138 divided by 2. Which equals 69. So right now, each game Yolanda did was 69 points. But, it says her second game score was 8 points lower. But it still has to be 138 points. So, you take away 8 points from S-69 (second game) and add 8 to F-69(First game) Which will equal 61 for S and 77 for F. So the answer is,
Yolanda's first game (F) was 77 points.
Yolanda's second game (S) was 61 points.
In total she scored 138 points.
Step-by-step explanation:
I hope this helped!
(brainliest appreciated!)
First answer!! :DHave a wonderful and blessed day!Yolanda’s scores for her first game, f is 73, and her second game, s is 65
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Yolanda’s bowling average for 2 games was 138.
f+s=138....(1)
Her second game score was 8 points lower than her first game score.
s=f-8....(2)
Substitute 2 in 1.
f+f-8=138
2f-8=138
Add 8 on both sides
2f=138+8
2f=146
Divide both sides by 2
f=73
s=73-8
s=65
Hence, Yolanda’s scores for her first game, f is 73, and her second game, s is 65
