Answer:
25/60 = 5/12
8/20 = 2/5
The Ratios do not form a proportion
Step-by-step explanation:
25/60:
25 ÷ 5/60 ÷ 5
= 5/12
8/20:
8 ÷ 4/20 ÷ 4
= 2/5

how much money is 18 figures?
Answer:
2.
Step-by-step explanation:
I don't know if it is right but thats what i got. You didnt really give enough information for me to solve it.
We have that an 18 figure is a Quintilllion=10^{18}
18 figure=10^{18}
Quintilllion
From the question we are told
How much money is 18 figures
Generally the denominations of money is is mathematically given as
Hundred=100
Thousand=1000
Million=1000000
Billion=1000000000
Quintilllion=10^{18}
Therefore
Therefore and 18 figure is a Quintilllion=10^{18}

Help pls. The number of questions that students missed on a 50 question science midterm is represented by the box and whisker plot below.
Which of the following statements is most likely to be true?
A. If the lowest grade of an A is an 88% then about 25% of the students earned an A.
B. About 25% of the students failed the exam.
C. About 75% of the students scored between 80% and 88% and earned a B.
D. If the lowest passing grade is 60% then some students failed the exam.
Answer: Read the step by step to learn and find the answer.
Step-by-step explanation:
We know that to grade something by percentage missing a certain amount of questions effects your grade. Think back to your last test. Maybe you got 3 or 4 wrong and ended up getting an 80 percent. Here we are going based off 50 questions. We know that if we get 19 questions wrong out of 50 we would get a 62%. If we got 14 wrong we would have a 72%. 9.5=81%. 6=88% and 4=92%. We already know the answer is NOT d or c because each section of the box and whisker is 25%. This means that the answer is 100% B. Especially because they asked what was most likely true and none of the other answers matched up.
To make the expression 4x-2 + (2x + 4) equivalent to 2(6x + 7), what must be the value in the box?
[tex]4x - 2 + (2x + 4) = 2(6x + 7) \\ [/tex]
[tex]4x - 2 + 2x + 4 = 12x + 14[/tex]
Simplification
[tex]6x + 2 = 12x + 14[/tex]
Subtract sides 2
[tex]6x + 2 - 2 = 12x + 14 - 2[/tex]
Simplification
[tex]6x = 12x + 12[/tex]
Subtract sides -12x
[tex]6x - 12x = 12x - 12x + 12[/tex]
Simplification
[tex] - 6x = 12[/tex]
Divided sides by -6
[tex] \frac{ - 6}{ - 6}x = \frac{12}{ - 6} \\ [/tex]
[tex]x = - 2[/tex]

Elsa Is taking physical fitness tests in her strength training class. Each day, her results are compared to her resutts from previous days. The first day she completes a test is considered the baseline, and Is represented by 0. For instance, on the first day she did the flexibility test, her result was calculated as 0. On the second day, in comparison to her first day's result, she was able to reach 1 1/16 inches less than the first day, which was recorded as -1 1/16. Then, on the third day, Elsa recorded a result of -5/8.
A. On which day did Elsa reach farther: the second or third day?
B. By how much?
Answer:
A) The second day
B) 9/16 inches
A) Elsa reached farther on the second day because -1/16 > -5/8
B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:
-1/16 - (-10/16) = 9/16
Elsa reached 9/16 inches farther on the second day then she did on the first.
Hope this helps and have a great day!

Hans is using frequent flier miles to fly to a location 750 miles away, but the airline he is using still charges $20.19 for fees and taxes and $0.15 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.15x + $20.19 How much did Hans pay for his trip?
Answer:
Cost of the trip = $132.69
Step-by-step explanation:
Given:
Total distance = 750 mile
Fixed charge = $20.19
Variable charges = $0.15 per mile
Find:
Cost of the trip
Computation:
Y = $0.15x + $20.19
Y = $0.15(750) + $20.19
Y = $132.69
Cost of the trip = $132.69

Answer: For the first part, her total savings would be $88, and for the second part, (let's pretend s = the total savings) the equation would be s = 40 + w x 6.
Step-by-step explanation: As for the first part, we would need to multiply her money per week times the amount of weeks she works. We can do this by simply multiplying the amount she makes (6) by the amount of weeks she works (8), resulting in 48, but we still have to add that number to the amount she already has, or 40, making $88 in total, as for the second part, this does a great job of explaining the reasoning behind that as well. Hope this answered your question!

All expression and phrase are filled below.
Here,
We have to filled all expression and phrase.
What is right angled triangle?
A right-angled triangle is a triangle, which has one of its interior angles equal to 90 degree.
Now,
Given that;
⇒ m∠CBD = 90 degree ….(i)
We have to prove triangle ABC is right angled triangle.
We can see that the line extends down and perpendicular to the line segment BC at point B.
We can also see that ∠ABC and ∠CBD are supplementary angle.
Hence, We prove as;
Statement Reason
1) m∠CBD = 90 degree ( Given )
2) ∠ABC and ∠CBD are supplementary. ( Because ABD is a line and
∠ABC and ∠CBD are linear
pair)
3). ∠ABC+∠CBD = 180 degree ( Definition of supplementary)
4) ∠ABC+ 90 = 180 degree ( m∠CBD = 90 degree )
5) ∠ABC + 90 - 90 = 180° - 90° ( subtraction property of equality)
∠ABC = 180° – 90° (from (i))
∠ABC = 90 degree
6) ∠ABC is a right angle. ( Definition of right angle)
7) Δ ABC is a right triangle. ( Definition of right triangle)
Therefore, according to definition of right angled triangle,
The triangle ABC is a right angled triangle.

Describe the end behavior of the graph f(x) using limits.
Answer:
um
Step-by-step explanation:
The end behavior of the graph f(x) using limits are
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
Option B is the correct answer.
We have,
From the graph,
As the x-value increases, the function y-values goes to -∞.
As the x-value decreases, the function y-values goes to -∞.
Now,
f(x) is the y-value.
The end behavior of the graph f(x) using limits can be represented as,

Point U is on line segment
TV
. Given TV=8 TU=2, determine the length uv
.
Answer:
Step-by-step explanation:
TV = VU + TU
Subsitute.
8 = VU + 2
-2 -2
VU = 6
A line segment is also a line but a line with finite length and fixed endpoints. The length of the line segment UV is 6 units.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
A line segment is also a line but a line with finite length and fixed endpoints.
Given that Point U is on the line segment TV. Therefore, it can be said that point U will lie between TV. Thus, we can write,
TV = TU + UV
As given the length of TV is 8 units, the length of TU is 2 units,
8 units = 2 units + UV
8 units - 2 units = UV
UV = 6 units
Hence, the length of the line segment UV is 6 units.

Samuel invested $53,000 in an account paying an interest rate of 6.7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 17 years?
Answer:
A≈165553.09
Step-by-step explanation:
To the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.
What is continuous compounding?The formula for calculating the amount of money in an account with continuous compounding is:
[tex]A = Pe^{(rt)}[/tex]
where:
A = the amount of money in the account after t years
P = the principal amount invested
r = the annual interest rate (as a decimal)
t = the time in years
e = Euler's number (approximately 2.71828)
Using this formula, we can calculate the amount of money in Samuel's account after 17 years as follows:
[tex]A = 53,000 \times e^{(0.067\times 17)[/tex]
A ≈ $174,529.50
Therefore, to the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.
