Answer: B. KL.
Step-by-step explanation:
A kiloliter (kl) is a unit which is derived from the metric SI (System International). This measurement is used when unit of volume with sides equal to one meter (1m) and as such, is equivalent to one cubic meter. One kiloliter (1kl) is which is same as one thousand liters (1000l). The kiloliter is used when volume of liquid is to be measured. This applies to a pool in the question.

Diego and Anya live 72 miles apart. They both meet at
their favorite restaurant, which is (16x – 3) miles from
Diego's house and (5x + 2) miles from Anya's house.
Diego argues that in a straight line distance, the restaurant
is halfway between his house and Anya's house. Is Diego
right? Justify your reasoning.
Answer:
The restaurant is not at half way
Step-by-step explanation:
Given
[tex]Total\ Distance = 72[/tex]
[tex]Diego = 16x - 3[/tex]
[tex]Anya = 5x + 2[/tex]
Required
Accept or reject Diego's claim
To do that, we need to determine the value of x by:
Diego + Anya =Total Distance
Substitute values for each parameter
[tex]16x - 3 + 5x + 2 = 72[/tex]
Collect Like Terms
[tex]16x + 5x = 72 + 3 - 2[/tex]
[tex]21x = 73[/tex]
Divide both sides by 21
[tex]x = \frac{73}{21}[/tex]
Substitute the value of x in Diego and Anya's distance
[tex]Diego = 16x - 3[/tex]
[tex]Diego = 16 * \frac{73}{21} - 3[/tex]
[tex]Diego = \frac{1168}{21} - 3[/tex]
[tex]Diego = \frac{1168 - 63}{21}[/tex]
[tex]Diego = \frac{1105}{21}[/tex]
[tex]Diego = 52\frac{13}{21}[/tex]
[tex]Anya = 5x + 2[/tex]
[tex]Anya = 5 * \frac{73}{21} + 2[/tex]
[tex]Anya = \frac{365}{21} + 2[/tex]
[tex]Anya = \frac{365 + 42}{21}[/tex]
[tex]Anya = \frac{407}{21}[/tex]
[tex]Anya = 19\frac{8}{21}[/tex]
Since, both distances are not equal,
Then Diego's claim is false and incorrect

The coordinates of the point 3/10 of the way from A to B are _
Answer:
(-1, -4.8)
Step-by-step Explanation:
Let the point be P, which is 3/10 of the way from A to B. This means, it divides P into AP and PB in the ratio, 3:10 = AP/PB = 3/10.
Apply the formula for internal division to find the coordinates which is given as:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] A(-4, -8) = (x_1, y_1) [/tex]
[tex] B(9, 6) = (x_2, y_2) [/tex]
[tex] m = 3, n = 10 [/tex]
Plug in the necessary values to find x and y coordinates for point P
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{3(9) + 10(-4)}{3 + 10} [/tex]
[tex] x = \frac{27 - 40}{13} [/tex]
[tex] x = \frac{-13}{13} [/tex]
[tex] x = -1 [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{3(6) + 10(-8)}{3 + 10} [/tex]
[tex] y = \frac{18 - 80}{13} [/tex]
[tex] y = \frac{-62}{13} [/tex]
[tex] y = \frac{-62}{13} [/tex]
[tex] y = -4.8 [/tex]
The coordinates of the point 3/10 of the way from A to B are (-1, -4.8)

Find the 44th percentile, P44, from the following data! pls help
Answer:
[tex] P_{44} = 29.9 [/tex]
Step-by-step Explanation:
The 44th percentile, [tex] P_{44} [/tex], of the given data can be calculated using the kth formula for percentile given as:
[tex] i = \frac{k}{100}(n + 1) [/tex]
where,
i = the ranking or the position of the percentile = ?
k = the percentile = 44
n = total number of the given data values = 23
Plug in the values into the formula to find "i"
[tex] i = \frac{44}{100}(23 + 1) [/tex]
[tex] i = \frac{44}{100}(24) [/tex]
[tex] i = \frac{1,056}{100} [/tex]
[tex] i = 10.56 [/tex]
Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.
Thus,
[tex] i_{down} = 10.56 = 10 [/tex]
[tex] i_{up} = 10.56 = 11 [/tex]
The data occupying the 10th position on the data set = 28.7
11th = 31.1
[tex] P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2} [/tex]
[tex] P_{44} = 29.9 [/tex]

travel at each rate?
Answer: He spends 1.5 hours on the first part of trip and 3 hours on the second part of trip
Step-by-step explanation:
Let x = the number of hours for first part
Let y = the number of hours for second part
Concept: speed × time = distance
----------------------------------------------------------------
x+y=4.5
59x+57y=259.5
-----
y=4.5-x
59x+57y=259.5
-----
59x+57(4.5-x)=259.5
59x+256.5-57x=259.5
2x+256.5=259.5
2x=3
x=1.5
4.5-1.5=3 hrs

The height of a helicopter above the ground is given by h=3.00t3, where h is in meters and t is in seconds. After 2.00 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground?S
Answer:
7.96 s
Step-by-step explanation:
Given the following :
h = 3t³
After t seconds, that is, t = 2
h = 3(2)³ = 3 × 8 = 24 m
Rate of change, Velocity = dh/dt
dh/dt = 3*3t^(3 - 1) = 3*3t² = 9t²
At t = 2 s ; initial velocity = 9(2)² = 9 × 4 = 36 m/s
From the 3rd equation of motion:
v² = u² + 2gh
Where g = acceleration due to gravity 9.8m/s
upward motion, g = - ve
Displacement = - 24
v² = 36² + 2(-9.8)(-24)
v² = 1296 + 470.4
v² = 1766.4
v = sqrt(1766.4)
= 42.03 m/s
Since final velocity is in downward direction : take it as negative.
Recall, :
Velocity = Displacement / time
Displacement = Velocity × time
Average Velocity = (Initial + final velocity) / 2
Displacement = - 24 m
-24 = [(36 + (-42.03)) /2] × t
-48 = - 6.03t
t = 48 / 6.03
t = 7.96s
Solve the equation for x. 3x=(2x−2)(m+5)
Answer:
[tex]x=\frac{-2m-10}{-2m-7}[/tex]
Step-by-step explanation:
Step 1: Write out equation
3x = (2x - 2)(m + 5)
Step 2: FOIL
3x = 2xm + 10x - 2m - 10
Step 3: Subtract 2xm on both sides
3x - 2xm = 10x - 2m - 10
Step 4: Subtract 10x on both sides
3x - 2xm - 10x = -2m - 10
Step 5: Factor out x
x(3 - 2m - 10) = -2m - 10
Step 6: Combine like terms in parenthesis
x(-2m - 7) = -2m - 10
Step 7: Divide both sides by -2m - 7
[tex]x=\frac{-2m-10}{-2m-7}[/tex]
how many times greater is the value of the 3 in 4,367 than the value of the 3 in 39?
Answer: Roughly 111.97
Step-by-step explanation:
1. 39 divided by 3 is 13.
2. 4367 divided by 3 is not evenly distributed. Rounding, it would work out to be roughly 1455.66
3. 1455.66 divided by 13 is roughly 111.97 (Again, this does not distribute evenly)
4. To check your work, multiply 111.97 times 13 and you should get somewhere around 1455.66 which is (4367 divided by 3).

Nadia’s bookshelf contains 10 fiction books, two reference books, and five nonfiction books. What is the probability that she randomly picks up a reference book and then, without replacing it, picks up a nonfiction book?
Answer:
5/136
Probability is the chance of an event happening.
Probability = (Favorable outcome)/(total outcome)
P(r and n) = 2/17 × 5/16
=(2 × 5)/(17 × 16)
= 10/272
= 5/136
Answer:
5/136, or about 3.68%
Step-by-step explanation:
There are 17 total books on the bookshelf and only two of them are reference books, so the probability that you randomly grab a reference book is 2 out of 17, or 2/17.
Now that you took out a reference book (and did not put it back) there are 16 books on the bookshelf and you know five of them are nonfiction. That means the probability of getting a nonfiction book on your second grab is 5/16.
To find the probability that both of these events happen, you multiply the two fractions together.
2/17 x 5/16 = 10/272, which can reduce to 5/136, or about 3.68%
When finding all the roots of polynomials, how do you find the possible rational zeros to know which numbers you plug back into the function to get the number you synthetically divide by?
Answer:
You would have to break the polynomial down into smaller binomials or monomials. Take x^2-6x-9 for instance. It would break down into (x+3)(x-3) through the a^2+2ab+b^2 formula. After that set the two nomials equal to zero and solve for x. After that, you would plug back in x to see whatever x works. You may more than two nomials after breaking it apart so keep that in mind.
Determine the scale factor for a circle with radius 9 in. to a circle with diameter 24 in. Type your answer as a fraction.
Answer:
bhhhhhhhhhhhhhhhhbhbhb
Step-by-step explanation:
3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The scale factor of a circle to another is the ratio of their radii
Radius of the first circle = 9 in
Diameter of the second circle = 24 in
Radius = Diameter / 2
Radius of the second circle = 24 / 2
Radius of the second circle = 12 in
Scale factor = (Radius of the first circle) / (Radius of the second circle)
Scale factor = 9/12
Scale factor = 3/4
Hence, 3/4 is the scale factor for a circle with radius 9 in to a circle with diameter 24 in.

Answer:
-1,325 ft below sea level
Step-by-step explanation:
0(surface level) - 1,500 = -1,500
-1,500 + 525 = -975
-975 - 350 = -1,325
Answer:
they are currently at -1325 ft.
Step-by-step explanation:
first yo go up or in other words you subtract 525 to 1500 which gives you 973 then they descend 350 so they are going back down so you add 350 onto 975
Which number has an 8 that is 1/10 the value of the 8 in 78?
Step-by-step explanation:
Step one:
Firstly we need to determine the place value of 8 in the term 78
in the term, we have 7 tens and 8 units
hence the place value of 8 in 78 is the units
Step two:
Now 1/10 of 8 is given as
0.1*8= 0.8
According to the problem statement, we are expected to find a number that has an 8 that is the same as 0.8.
Say 5.8, 6.8, 9.8
we cannot say exactly, but any number that has an 8 that is one decimal away is an equivalent
Rewrite the following expression as a single logarithm: log7(x2+5x−14)−log7(x+7)
Answer:
log7(x-2)
Step-by-step explanation:
Use of property: log(ab) = log(a) + log(b)
log7(x²+5x−14)−log7(x+7) = log7(x+7)(x-2) - log7(x+7) =log7(x+7) + log7(x-2) - log7(x+7) = log7(x-2)-61 times the difference between a number and 56 is equal to the number plus – 28.
Solve the equation for z. Express your answer as an integer, a reduced fraction, or a decimal number rounded to two places.
Answer:
1722/31 or 55.55
Step-by-step explanation:
We need to write an equation.
-61( z - 56 ) = z - 28
-61z + 3416 = z - 28
-61z + 61z + 3416 = z + 61z - 28
3416 = 62z - 28
3416 + 28 = 62z - 28 + 28
3444 = 62z
3444/62 = 62z/62
3444/62 = z
Since 3444/62 isn't a whole number let's reduce
3444/2 = 1722 62/2 = 31
1722/31 is our reduced fraction
Plug it into a calculator 55.5483 but rounded to two decimal places is 55.55
