The solution would be like this for this specific problem:
Given:
46547 17395 25765 11325 14071 61688
You want two-digit numbers between 01 and 50, so break it up into chunks of two and eliminate any string that is not between 01 and 50.
So, the numbers from the string are:
46 54 71 73 95 25 76 51 13 25 14 07 16 16 88
Eliminated numbers:
54 71 73 95 25 76 51 88
Numbers remaining:
46 25 13 14 07 16
So, the 2 contestants from a game show out of a pool of 50 would be 46 and 25 (since these are the possible contestants based from the given).
An airplane is flying at 180mph. A jet flying at 330 mph leaves 1 hour later traveling in the same direction. How long will it take for the jet to catch up to the airplane?
Answers
To determine how long it will take for the jet to catch up to the airplane, calculate the time by dividing the distance the airplane covers before the jet starts (180 miles) by the relative speed of the jet to the airplane (150 mph), resulting in 1.2 hours or 72 minutes.
Explanation:The subject of the question is related to the topic of relative velocity in Mathematics, specifically regarding two objects moving in the same direction. To find out how long it will take for the jet to catch up to the airplane, we need to calculate the relative speed of the two vehicles and the time it takes for one to overtake the other.
The airplane is moving at 180 mph, and the jet is flying at 330 mph. Since the jet leaves one hour later, the airplane would have traveled 180 miles by that time. The relative speed of the jet to the airplane is the difference between their speeds, which is 330 mph - 180 mph, resulting in 150 mph.
To catch up, the jet needs to cover the 180 miles separation distance at a relative speed of 150 mph. We can find the time it takes to catch up by dividing the distance by the relative speed:
Time = Distance ∗ Relative Speed = 180 miles ∗ 150 mph = 1.2 hours.
Therefore, it will take 1.2 hours or 72 minutes for the jet to catch up to the airplane after it starts its pursuit.
Express log2 6 + log2 7 as a single logarithm.
Answers
log a + log b = log a*b
Here you are adding two logs to the base 2, and your result will also be a log to the base 2.
log to the base 2 of 6 PLUS log to the base 2 of 7 results in:
"log to the base 2 of 6*7," or "log to the base 2 of 42."
Answer: The correct option is (C) [tex]\log_242.[/tex]
Step-by-step explanation: We are given to express the following logarithmic expression as a single logarithm :
[tex]E=\log_26+\log_27~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(I)[/tex]
We will be using the following logarithmic property :
[tex]\log_ab+\log_ac=\log_a(bc)[/tex]
So, from expression (i), we get
[tex]E=\log_26+\log_7=\log_2(6\times 7)=\log_242.[/tex]
Thus, the required single logarithm is [tex]\log_242.[/tex]
Option (C) is CORRECT.

Let $abcd$ be a parallelogram. extend $\overline{bc}$ past $b$ to $f$, and let $e$ be the intersection of $\overline{ab}$ and $\overline{df}$. if the areas of triangles $bef$ and $ade$ are 1 and 9, respectively, find the area of parallelogram $abcd$.
Answers
Triangles ade and bef are similar due to equal angles. The ratio of their areas (9:1) means their sides have a ratio of 3:1. Using the properties of parallelograms, the parallelogram's area will be double the area of triangle ade, or 18 square units.
Explanation:In the given problem, we have a parallelogram abcd and we're asked to find its area. Given the properties of a parallelogram, we know that angle bad equals angle bef. This leads to the conclusion that triangle ade is similar to triangle bef since their angles are the same. As the ratio of their areas is 9:1, it's clear the ratio of their sides is 3:1, since the ratio of the areas of similar figures is the square of the ratio of their corresponding sides.
The parallelogram's area will be double the area of triangle ade, thanks to the properties of a parallelogram (it's made up of two congruent triangles). Therefore, the area of the parallelogram is 18 square units. The important steps here were recognizing the similar triangles and knowing how to calculate a parallelogram's area.

How does the volume of an oblique cone change if the height is reduced to 2/5 of its original size and the radius is doubled?
Answers
V=1/3πr^2h
r=2r
h=2/5h
thus;
V=1/3*π*(2r)^2(2/5h)
=8/15πr^2h
This implies that the new volume will be 8/15 of the original volume
Answer:
Option (D) is correct.
Step-by-step explanation:
Let the initial original height of the cone is h and radius is r.
The volume of original cone is given by
[tex]V=\frac{1}{3}\times \pi r^{2}\times h[/tex]
Now the new height be h' = 2/5 h and radius r' = 2r
So, the new volume be
[tex]V'=\frac{1}{3}\times \pi r'^{2}\times h'[/tex]
[tex]V'=\frac{1}{3}\times \pi\times 2r^{2}\times \frac{2}{5}h[/tex]
[tex]V=\frac{8}{15}\times \pi \times r^{2}h[/tex]
what are the discontinuities of the function f(x)= (x^2 - 36)/(4x - 24)
Answers
The function f(x) = (x² - 36)/(4x - 24) has a removable discontinuity at x = 6, due to the fact that at this value the original function's denominator becomes zero.
The function given is f(x) = (x² - 36)/(4x - 24). To find the discontinuities of this function, we must identify values of x that cause the denominator to be zero, as the function would be undefined at those points. Factor the numerator and the denominator to simplify the expression. (x² - 36) can be factored as (x + 6)(x - 6), and (4x - 24) can be factored as 4(x - 6). So, the simplified function is f(x) = (x + 6)/4, but we must exclude the value x = 6 from the domain due to it making the original denominator zero. Therefore, the function is discontinuous at x = 6, which is also known as a point of removable discontinuity because the factor (x - 6) is canceled out in the simplification.

The answer would be that Michael drove 17 hours and Sarah drove 20 hours.
Work:
x+x+3=37
(combine like-terms)
2x+3=37
(subract 3 from each side of the equation)

On a particular day, the wind added 4 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 4 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 57 miles with the wind, she could go only 33 miles against the wind.What is her normal rowing speed with no wind?
Answers
Answer:
15 mph
Step-by-step explanation:
Speed of wind = [tex]V_w[/tex] = 4 mph
Speed of Jaime rowing = [tex]V_r[/tex]
Speed of boat against wind = [tex]V_r-4[/tex].
Speed of boat with wind = [tex]V_r+4[/tex]
Time taken with and against wind is same = t
Distance travelled with wind = 57 mph
Distance travelled against wind = 33 mph
[tex]time=\frac{\text{Distance}}{\text{Speed}}[/tex]
Time taken to go with wind
[tex]t=\frac{57}{V_r+4}[/tex]
Time taken to go against wind
[tex]t=\frac{33}{V_r-4}[/tex]
So,
[tex]t=\frac{57}{V_r+4}=\frac{33}{V_r-4}\\\Rightarrow \frac{57}{33}=\frac{V_r+4}{V_r-4}\\\Rightarrow 57V_r-33V_r-228-132=0\\\Rightarrow V_r=\frac{360}{24}\\\Rightarrow V_r=15\ mph[/tex]
∴ Her normal rowing speed with no wind is 15 mph
The equation y = ax describes the graph of a line. If the value of a is negative, the line
Answers
The equation y = ax represents a straight line with slope a. If a is negative, the line slopes downward to the right, not down and to the left.
The equation y = ax describes the graph of a line. The & in the equation appears to be a typo and should likely refer to a. The constant a represents the slope of the line. When the slope a is negative, the line slopes downward as it moves to the right on a coordinate plane. This is because a negative slope indicates that as the independent variable (usually the x-axis) increases, the dependent variable (y-axis) decreases. A line with a negative slope is straight, and its steepness depends on the absolute value of the slope a. Thus, the line goes down and to the left.
