Step-by-step explanation:
Nathan usually drinks 33 ounces of water per day. He read that he should drink 59 ounces of water per day. If he starts drinking 59 ounces, what is the percent increase? Round to the nearest percent.
Step-by-step explanation:
33oz = 100%
1% = 100%/100 = 33/100 = 0.33oz
59 - 33 = 26oz increase
how many % are these 26oz compared to the original 33oz ?
we need to see how often 1% fits into 26oz.
26/0.33 = 78.78787878...%
rounded this means a 79% increase of drinking water.
if buying a pound of something is 6$ how much is 2.6 pounds
Answer: 15.6
Step-by-step explanation: 2.6 x 6 = 15.6
Answer:
$15.60
Step-by-step explanation:
If buying a pound of something is $6 then 2 pounds is $12.
0.6 pounds would be $3.60
1 = $6
0.9 = $5.40
0.8 = $4.80
0.7 = $4.20
0.6 = $3.60
0.5 = $3.00
0.4 = $2.40
0.3 = $1.80
0.2 = $1.20
0.1 = $0.60
0 = $0.00
subtract by .60 or 60 cents

1 1/4% in simplest form
Answer:
It can be written as 0.25 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Answer:
It is already in the simplest form, but you can convert It into many things.
Step-by-step explanation:
Make this into an improper fraction you: 1 x 4 + 1 then put the answer on the numerator and keep the denominator.
Mixed number = 5/4
Decimal = 1.25
because 1/4 = 0.25
and 1 is a whole number.

Step-by-step explanation:
An urn contains p black balls, q white balls, and r red balls; and n balls are chosen without replacement. a. Find the joint distribution of the numbers of black, white, and red balls in the sample. b. Find the joint distribution
The joint distribution of the numbers of the three colours in the sample without replacement is:
[tex]\mathbf{P(A=a,B=b,C=c) = \dfrac{\Big( ^{p}_{ A} \Big) \Big( ^{q}_{ B} \Big) \Big( ^{r}_{ C} \Big) }{ \mathbf{\Big( ^{p+q+r}_{ \ \ \ n} \Big) } }\ \ \ \ where; n = A+B+C}[/tex]
Let consider A, B, and C to denote the three variables that are black, white, and red balls in the sample.
i.e.
n = A + B + C
Now, the numbers of ways 'n' balls are chosen without replacement in an urn that comprises of p black balls, q white balls, and r red balls can be computed as follows:
[tex]\mathbf{\implies \Big( ^{p+q+r}_{ \ \ \ n} \Big) }[/tex]
Now, the number of ways whereby A black balls can be chosen from p black balls is expressed as:
[tex]\mathbf{\implies \Big( ^{p}_{ A} \Big) }[/tex]
The number of ways whereby B white balls can be chosen from q white balls is expressed as:
[tex]\mathbf{\implies \Big( ^{q}_{ B} \Big) }[/tex]
The number of ways whereby C red balls can be chosen from r red balls is expressed as:
[tex]\mathbf{\implies \Big( ^{r}_{ C} \Big) }[/tex]
Therefore, we can conclude that the joint distribution of the numbers of the three colours in the sample without replacement is:
[tex]\mathbf{P(A=a,B=b,C=c) = \dfrac{\Big( ^{p}_{ A} \Big) \Big( ^{q}_{ B} \Big) \Big( ^{r}_{ C} \Big) }{ \mathbf{\Big( ^{p+q+r}_{ \ \ \ n} \Big) } }\ \ \ \ where; n = A+B+C}[/tex]

A sum of 2 integers is 41 and their difference is 5. Find the integers.
Answer:
A = 22
B = 19
Explanation:
Numbers one and two will be a variable A and B respectively.
A + B = 41 Equation one
A + B = 5 Equation two
Isolate one of the variables. Let's use A
A + B = 41 = A = 41 - B
Now replace the A in Equation two.
(41 - B) - B = 5
Simplify: 41 - 2B = 5
Isolate variable: 38 = 2B --> B = 19
Use the value of B to find A
A = 41 - B = 41 - 19 = 22
So the answer is A = 22 and B =19

There are 25 students in a class. 20% of the the students are in a club. How many students are in a club?
Answer:
5
Step-by-step explanation:
When taking a percent of a number, multiply the number by the percent divided by a hundred:
[tex]25 * \frac{20}{100}[/tex]
You get an answer of
5
Answer:
5 students are in a club.
Step-by-step explanation:
To do 20% of 25, you must first move the % until all numbers are on the right side of the decimal.
Observe: 20% ---> 0.20 aka 0.2
Now, you must take 0.2 and multiply it by 25 to get 20% of 25.
0.2 x 25 = 5
There's your answer, 5 students in a club :)

*enter your lengths to the NEAREST TENTH
Answers:
FG = 8.5 GH = 11.4 FH = 17.5 JK = 11.4 KL = 17.5 JL = 8.5The triangles are congruent by SSS=======================================================
Explanation:
Use the distance formula to compute the length of each segment. For instance, the distance from point F to point G is the length of segment FG.
I'll show the steps on finding the length of FG
[tex]F = (x_1,y_1) = (-5,10)\\\\G = (x_2,y_2) = (-2,2)[/tex]
[tex]d = \text{distance from F to G}\\\\d = \text{length of segment FG}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-5-(-2))^2+(10-2)^2}\\\\d = \sqrt{(-5+2)^2+(10-2)^2}\\\\d = \sqrt{(-3)^2+(8)^2}\\\\d = \sqrt{9+64}\\\\d = \sqrt{73}\\\\d \approx 8.544\\\\d \approx 8.5\\\\[/tex]
The length of segment FG is approximately 8.5 units. The other side lengths are handled in the same way. As an alternative, you can use the pythagorean theorem.
---------------------
Once you determine all six lengths, note we have the following three pairs of corresponding congruent sides:
FG = JL = 8.5GH = JK = 11.4FH = KL = 17.5Because we have three pairs of equal sides, this means we can use the SSS (side side side) congruence theorem to prove the triangles are congruent. In other words, we have two identical triangles. One triangle is a rotated and reflected copy of the other.
The diagram is below.

Graph y + 14 = -7x help me pls
Answer:
see attached graph
Step-by-step explanation:
There are a couple of ways you can look at this.
Point-Slope Form
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Comparing this to the given equation, we see that ...
k = -14, m = -7, h = 0
That is, the equation describes a line with slope -7 through point (0, -14).
The slope is the ratio of rise to run. Usually, "run" is considered to be positive in the +x direction (to the right). Here, you run out of room on most graphs if you look for a point that is 7 units down and 1 unit right of the y-intercept at (0, -14). (That point is (1, -21).) So, it is more convenient to start at the y-intercept (0, -14) and go 1 unit left and 7 units up to find another point on the line. That point is (-1, -7). With two points plotted, you can draw the graph.
__
Slope-Intercept form
We discovered above that the y-intercept is -14. You can get there also by putting the equation in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept (0, b)
Adding -14 to both sides of the given equation gives you this form.
y = -7x -14
The method of plotting is substantially identical to that described above.
__
Standard form
The standard form of the equation is ...
ax +by = c
where a > 0, and a, b, c are mutually prime integers.
Adding 7x-14 to both sides of the equation puts it into standard form:
7x +y = -14
The x- and y-intercepts are found by setting the other variable to zero and solving for the one that is left. Here, that means the x-intercept is ...
c/a = -14/7 = -2
and the y-intercept is ...
c/b = -14/1 = -14
These x- and y-intercepts are easily plotted on the x- and y-axes. The graph will be the line drawn through them. The attached graph shows the line and the intercepts.
$4.95 marked up 80%
Answer:
$8.91
Step-by-step explanation:
Multiply $4.95 times 0.80 ( convert 80% to a decimal ) and that will equal 3.96 .
Then , since you're marking it up , you're gonna add the 3.96 to 4.95 which will equal $8.91 .
