joe loses 6 pounds during basketball practice. how many cups of water must he consume to replenish this loss
In order to regain the amount of water Joe losed during practice he should drink 10 cups of water.
A pound is equivalent to 453.59 mg, whereas a cup is equivalent to 236.59 ml.
You may roughly calculate that 2 cups equal 1 pound of water. The density should be 1 mg/ml if the fluid is mostly water.
The number of cups will be,
6 pounds * 453.59 (mg/pounds) * (1mg/ml) / (236.59 ml/cups)
= 10 cups .
Water is a crucial component for all living things, including people and other animals. Naturally, the water must go somewhere when it ascends the plant. Water loss will result from water evaporation (transpiration in plants)
Our breath, skin, urine, and sweat all cause water loss. A person's body will typically consume 2.5 L of water every day and expend the same amount. Your body will "inform you" you are thirsty and need to drink water if you get dehydrated (Figure 5). You have undoubtedly also noticed that when you drink less water, your pee is more concentrated.

Answer:
4.) a.) 2.01 b.) 404.01
6.) a.) 152.17 b.) 18412.17 c.) 153.14 d.) 18565.60
Step-by-step explanation:
To solve, use the exponential growth formula [tex]A_t=A_0(1+\frac{r}{p})^t[/tex] where
[tex]A_t[/tex] = Amount as a function of time
[tex]A_0[/tex] = Original amount
[tex]r[/tex] = rate
[tex]p[/tex] = period
[tex]t[/tex] = time
For question 4, let
[tex]A_0=400\\r=0.06\\p=12\\t=2[/tex]
So,
[tex]A_t=400(1+\frac{0.06}{12})^2\\A_t=400(\frac{201}{200})^2\\A_t=400(1.01)\\A_t=404.01[/tex]
So, the second-period interest would be 404.01-402=2.01
Question 6 can be solved using the same formula, but let
[tex]A_0=18260\\r=0.025\\p=\frac{12}{4}=3\\t_1=1\\t_2=2[/tex]
So,
[tex]A_t=18260(1+\frac{0.025}{3})^1\\A_t=18260(\frac{121}{120})^1\\A_t=18412.17[/tex]
The first-period interest would be 18412.17-18260=152.17
For the second-period, use [tex]t_2[/tex]:
[tex]A_t=18260(1+\frac{0.025}{3})^2\\A_t=18260(\frac{121}{120})^2\\A_t=18260(1.02)\\A_t=18565.60[/tex]
The second-period interest would be 18565.60-18412.17=153.43

Answer:
B
Step-by-step explanation:
Determine the equation of the line given by the table and compare with given options.
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 9) and (x₂, y₂ ) = (7, 19) ← 2 ordered pairs from the table
m = [tex]\frac{19-9}{7-2}[/tex] = [tex]\frac{10}{5}[/tex] = 2 , then
y = 2x + c ← is the partial equation of the line
to find c substitute any ordered pair from the table into the partial equation.
using (6, 17 ), that is x = 6, y = 17 , then
17 = 12 + c ⇒ c = 17 - 12 = 5
y = 2x + 5 ← equation of line from table, with y- intercept c = 5
thus the function with a y- intercept greater than the table line is B

What are Supplementary Angles?
Supplementary angles, when added together will give us a sum of 180°.
Linear pair angles and corresponding angles are supplementary.
Thus, to prove that ∠1 is supplementary to ∠3:
We are given that lines m and n are parallel.
∠1 and ∠3 are corresponding angles.
So therefore, ∠1 = ∠3 by the corresponding angles postulate.
∠2 and ∠3 are linear pair, their sum therefore equals 180° based on the definition of supplementary angles.
Based on the substitution property, we have the following:
m∠2 + m∠3 = m∠1 + m∠3
m∠1+m∠3=180°
Therefore, ∠1 is supplementary to ∠3 based on the definition of supplementary.
The missing statements and reasons to proof that ∠1 is supplementary to ∠3 are:

What does a quadratic equation's vertex form mean?x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem. The answer could be simple or complicated.
This quadratic equation, which has the form y=a(x-h)2 + k, is referred to as being in vertex form. It is so named because the vertex point (peak point) lies on the graph of this equation (h,k)
We may deduce from the facts above that
-4.9 t2 + 19.6 t + 58.8 = 0
The equation will logically fit into the square upon completion.
y = a(x-h)^2 + k
where h will be the time it takes to get to a height of k.
-[tex]4.9t^{2}[/tex] + 19.6t + 58.8 = 0
-[tex]4.9t^{2}[/tex] + 19.6t = - 58.8
-4.9( [tex]t^{2}[/tex] - 4t ) = -58.8
Now take half the linear term, square it, and add it to both sides.
-4.9( [tex]t^{2}[/tex] - 4t ) = -58.8
-4.9( [tex]t^{2}[/tex] - 4t + 4 ) = -58.8 + 19.6
-4.9 [tex](t-2)^{2}[/tex] = - 78.8
s(t) = -4.9 [tex](t-2)^{2}[/tex] + 78.8

the mean recurrence interval (mri) of an earthquake in the 8.0-9.0 magnitude range in the los angeles area is approximately 1,500 years. based on this, what is the probability of an earthquake in this magnitude range sometime in the next 30 years?
Using the Poisson distribution, the probability of an earthquake in the 0.8-0.9 magnitude range sometime in the next 30 years is
1 - 1.9287 x 10⁻²².
It is given that mean recurrence of an earthquake is the 8.0-9.0 magnitude is approximately 1500 years.
We have to find the probability of an earthquake in this magnitude range sometime in the next 30 years.
Since, an occurrence of an earthquake is a rare event, we can use Poisson distribution here.
Poisson distribution gives the probability of occurrence of any event in a given time interval.
Let the average number of event per year in 30 years of period is λ.
[tex]\lambda = \frac{1500}{30}[/tex]
λ = 50
Let, the occurrence of an earthquake is a random variable x.
Then the probability that at least an earthquake occur in next 30 years is calculated as:
P(x ≥ 1) = 1 - P(x<1)
P(x ≥ 1) = 1- P(x=0) -----(1)
PDF of Poisson distribution with parameter λ is given as:
[tex]P(X = x) = \dfrac{e^{-\lambda}{\lambda}^x}{x!}[/tex]
So, in this case
[tex]P(x=0)= \dfrac{e^{-50}{(50)}^0}{0!}[/tex]
[tex]P(x=0)= \dfrac{1.9287 \times 10^{-22}}{1}[/tex]
[tex]P(x=0)={1.9287 \times 10^{-22}[/tex]
Substitute this value in equation (1)
P(x ≥ 1) = 1 - 1.9287 x 10⁻²²
Hence, the probability of an earthquake in next 30 years is
1 - 1.9287 x 10⁻²².

imagine you compare the effectiveness of four different types of stimulants to keep you awake while revising statistics using a one-way anova. the null hypothesis would be that all four treatments have the same effect on the mean time kept awake. how would you interpret the alternative hypothesis?
The alternative hypothesis in this case would be that at least one of the four treatments has a different effect on the mean time kept awake compared to the others.
If the one-way ANOVA test rejects the null hypothesis, it means that there is a significant difference in the mean time kept awake among the four treatments. This means that at least one of the treatments is more effective in keeping you awake than the others. It is important to note that the alternative hypothesis does not specify which of the treatments is more effective, only that at least one is different from the others. To determine which treatment is more effective, you would need to conduct additional tests, such as post-hoc tests.

pls help
Rick should order part number G371-7 So the option A is the correct Answer
What is a part number ?
Part designs or materials are identified by part numbers, which are sometimes abbreviated as PN, P/N, part no., or part #. Its goal is to make referencing to that thing simpler. A part number clearly identifies a part design both inside and occasionally outside of a single organization. For instance, it is simpler to identify a screw as "HSC0424PP" rather than "Hardware, screw, machine, 4-40, 3/4" long, pan head, Phillips." The part number in this illustration is "HSC0424PP," which may be prefixed in database fields as "PN HSC0424PP" or "P/N HSC0424PP."
A serial number is a specific identifier of a specific instantiation of a part design, much as a part number identifies a component design (regardless of its instantiations). To put it another way, a part number designates each specific (physical) item as having been manufactured to a specific, original design;
As part number G371-7 fits perfectly to the desired requirement of float diameter of less than 8 inches, weigh more than 1 pound, and fit a 5/16-SAE spud connection that's why it is the correct answer

The vertex (0,2) of the parabola's vertex shape, which can expand upward or downward, equals (x - 0)² + 2.
What is parabola?
Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve.
What is a vertex form of an equation?
An equation's conventional vertex form is written as:
f(x) = (x-h)² + k where;
(h, k) is the vertex
Vertex (0,2) should be replaced in the equation's vertex form.
f(x) = (x - 0)² + 2
As a result, vertex (0,2) of the parabola with an opening up or down is equal to (x - 0)² + 2.

Brian started cleaning at 3:33 PM and finished at 4:21 PM. How long did it take him.
Brian started cleaning at 3:33 PM and finished at 4:21 PM. The correct answer is 48 minutes
How did we figure this out?First, we are figuring out what is given we are counting numbers or we can add to get to 4:21 PM.
Counting numbers:
[tex]\boxed{3:33=3:34=3:35=3:36=3:37=3:38=3:39=3:40 }[/tex]
Add the numbers:
[tex]\boxed{3:33+7=3:40+10=3:50+10=4:00+21=4:21}[/tex]
If we add the numbers it would be faster.
Therefore, when we add we get are answer.
Therefore, Brian started cleaning at 3:33 PM and finished at 4:21 PM. The correct answer is 48 minutes
Answer:
48

I NEED HELP NEOW PLS
Step-by-step explanation:
SWT + TWU =180º therefore SWU must be a line. Aka SWU is linear. So SWT and TWU must be a linear pair.
SWT + SWT = 180º therefore 2SWT=180º deviding both sies by 2 we get SWT = 90º Therefore SWT is replacing TWU. SWT is substituted into TWU. So substitution.
SU | TV basically means the line that passes through both points S and U is perpendicular to the line that passes through both points T and V. Therefore it is the Defenition of perpendicular lines.
If this helped please rate the answer.
