Emil starts the day with 16 liters of lemonade if he is left with 4 liters by the end of the day. Computed using the fractional values given.
Let the initial quantity of lemonade with Emil be x liters.
Quantity sold by Emil in the morning = Half of his lemonade = (1/2)x liters, that is half fraction of x.
Quantity left with Emil = x - x/2 = x/2 liters, that is half fraction of x.
Quantity sold by Emil at lunchtime = Quarter of what was left = (1/4)(x/2) liters = x/8 liters, that is the one-eight fraction of x.
Quantity left with Emil = x/2 - x/8 = 3x/8 liters, that is the three-eight fraction of x.
Quantity sold by Emil in the afternoon = One-third of what was left = (1/3)(3x/8) liters = x/8 liters, that is the one-eight fraction of x.
Quantity left with Emil = 3x/8 - x/8 = x/4 liters, that is the quarter fraction of x.
Now, we are said that Emil closes for the day with 4 liters remaining.
Therefore, x/4 = 4, or, x = 4*4 = 16 liters.
Therefore, Emil started the day with 16 liters of lemonade.

Which graph corresponds to the table? Giving brainliest to accurate answer.
Answer:
Last graph that slopes upwards from left to right and that has an y-intercept of -1
Step-by-step explanation:
let us pick some points!(you can chose any two)
when x =3 , y = 14 : helps us get points (3,14)
when x =1 , y = 4 : helps us get points (1,4)
so we find the gradient using the two points:
[tex]gradient \ =\frac{14-4}{3-1} =\frac{10}{2} \\[/tex]
we now use gradient 10/2 and point (1,4) to find the equation of the line:
[tex]\frac{10}{2} =\frac{y-4}{x-1} \\2(y-4)=10(x-1)\\2y-8=10x-10\\2y=10x-10+8\\2y=10x-2\\y=5x-1[/tex]
from the equation of the line found we are able to find the y- intercept of the line is -1 and that the line has a positive gradient thus should slope upwards from left to right.
From the pictures you posted, we pick the last graph as it seem to slope upwards from left to right and has the line cutting y axis at around -1

(b) Let x = 1.1609... be the positive real number such that [tex]4^x=5[/tex]. Prove that x is irrational.
Answers:
(a) x = 0.5
(b) Given Below.
Explanation:
(a)
[tex]4^x = 2[/tex]
apply ln both sides
[tex]ln(4^x) = ln(2)[/tex]
simplify
[tex]xln(4) = ln(2)[/tex]
divide both sides by ln(4)
[tex]x = 0.5[/tex]
(b)
Recall that rational numbers can be expressed in fractions a/b
[tex]4^x = 5[/tex]
apply ln on both sides
[tex]ln( 4^x) = ln(5)[/tex]
simplify
[tex]xln( 4) = ln(5)[/tex]
divide both sides by ln(4)
[tex]x =\frac{ ln(5)}{ln(4)}[/tex]

Write 32.5% as a fraction in simplest form.
Answer:
13/40
Step-by-step explanation:
Rewrite a percentage as a decimal: [tex]\frac{32.5}{100}[/tex]
Convert decimals to integers: [tex]\frac{325}{100}[/tex]
Reduce the fraction: [tex]\frac{13}{40}[/tex]
Answer: [tex]\frac{13}{40}[/tex]
32.5% as a fraction in simplest form is 13/40.
Here we have to find fractional form of 35 percent
Since we knw that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
To convert a percentage to a fraction,
we can simply write it as a fraction with a denominator of 100.
Then,
we simplify the resulting fraction to its simplest form.
For 32.5%,
we can write this as,
⇒ 32.5/100
Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF).
The GCF of 32.5 and 100 is 12.5,
so we can divide both by 12.5,
⇒ 32.5/100 = (32.5 ÷ 12.5) / (100 ÷ 12.5)
= 13/40
Therefore, 32.5% as a fraction in simplest form is 13/40.

A real estate agent is working for a developer who claims that the average commute time to downtown is 20 minutes with a standard deviation of 7 minutes. Stephon is an independent real estate agent and wants to check the times for his client. He took a random sample of 15 commute times and found an average of 26 minutes. He did hypothesis testing using a significance level of 5%. Which conclusion could he make?
The z-statistic is 0.22, so the null hypothesis should not be rejected.
The z-statistic is 1.69, so the null hypothesis should not be rejected.
The z-statistic is 3.32, so the null hypothesis should be rejected.
The z-statistic is 3.67, so the null hypothesis should be rejected.Tyesha found that the z-statistic was 2.1 and that the critical z-values were -1.96 and 1.96. Which of the following is a valid conclusion based on these results?
One can reject the null hypothesis.
One can reject the alternate hypothesis.
One can accept the null hypothesis.
One cannot accept or reject the null hypothesis.
The correct option is C which is The z-statistic is 3.32, so the null hypothesis should be rejected. One can reject the null hypothesis.
What is the null hypothesis?When there are two possibilities then we calculate the null hypothesis if the hypothesis is true hypothesis is accepted if it is
To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.
The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypothesis is a contradiction of the null hypothesis which is that the average commute time to downtown is not 20 minutes.
i.e. H0: μ = 20 and H1: μ ≠ 20.
The z-statistics is given by (sample mean - hypothesized mean) divided by (standard deviation divided by the square root of the sample size).
i.e.
[tex]z= \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]
x = 26, [tex]\mu[/tex] = 20, [tex]\sigma[/tex] = 7 and n = 15 putting the values in the question we will get the z-score value.
[tex]z = \dfrac{26-20}{\dfrac{7}{\sqrt15}}[/tex]
z = 6 / 1.807
z = 3.32

Sasha made a model of a clipper ship. If her model has a length of 18 inches, and the original ship has a length of 160 feet and a width of 32 feet, what should be the width of her model?
The width of the model is 3.6 inches.
What are Similar Figures?The figures with the same shape are said similar when the sides of both the figures are in proportion.
Sara has a model of length = 18inches.
The original ship has a length is 160 ft
The width of the original ship is 32 ft
The model is a scaled-down version of the original figure and so the length and width of the model will be in the same proportion as the original dimensions.
Let x represents the width of the model then,
160/18 = 32/x
x = 32 * 18 / 160
x= 3.6 inches.
Therefore, the width of the model is 3.6 inches.

According to the graph, what is the value of the constant in the equation
below?
Height = Constant - Width
Answer:
B) 0.5
Step-by-step explanation:
The given formula is:
Height = Constant * Width
You may now choose any point on the graph (the horizontal line represents a point for width, and the vertical line represents a point for height) and put it into the specified formula. Let's test the two supplied points (2, 1):
Now, 2 is on the horizontal line, so we put it in for width, and 1 is on the vertical line, so we plug that in for height. When we do it, we get:
1 = C * 2
(In the expression above we need to solve for C, and we can do that by dividing both sides by 2)
C= 1/2 = 0.5
So, the answer is 0.5 or option B.

The ratio of the numerator to the denominator of a certain fraction is one to four. If three is added to the numerator and
subtracted from the denominator, the new fraction reduces to one-third. What is the original fraction?
A 12/45
B 15/45
C 12/48
Answer:
C 12/48
Step-by-step explanation:
Original fraction:
x/y
The ratio of the numerator to the denominator is 1:4, so
x/y = 1/4
Cross multiply:
y = 4x
If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.
(x + 3)/(y - 3) = 1/3
Cross multiply:
3(x + 3) = 1(y - 3)
3x + 9 = y - 3
Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.
3x + 9 = 4x - 3
12 = x
x = 12
y = 4(12) = 48
The original fraction is x/y = 12/48

Flying the SR-71A jet, Capt. Elden W. Joersz, USAF, set a record speed of 2193.16 miles per hour. At this speed, the algebraic expression 2193.16t gives the total distance flown in t hours. Find the distance flown by the SR-71A in 1.7 hours.
Final answer:
The required distance is 3728.372 miles.
Step-by-step explanation:
Step 1
The distance flown is t hours given by:
2193.16t
Step 2
Let distance be represented by d, thus:
d = 2193.16t
Step 3
d = 2193.16t
Substitute t = 1.7 in the relation:
d = 2193.16 x 1.7
Step 4
Solve for d:
d = 2193.16 x 1.7
d = 3728,372
