Which fractions are equivalent to 9 6
Answer:
2/3
Step-by-step explanation:
The fractions which are equivalent to the fraction [tex]\frac{9}{6}[/tex] from the given options are [tex]\frac{3}{2}[/tex] and [tex]\frac{12}{8}[/tex], which are options (A) and (C).
Given a fraction [tex]\frac{9}{6}[/tex].
It is required to find the fraction which is equivalent to the given fraction.
If two fractions are equivalent, then they will be proportional.
The fraction [tex]\frac{9}{6}[/tex] can be written as [tex]\frac{3*3}{2*3}[/tex].
Here, when 3 gets canceled, the resulting fraction is [tex]\frac{3}{2}[/tex].
So, [tex]\frac{3}{2}[/tex] is equivalent to [tex]\frac{9}{6}[/tex].
And, [tex]\frac{3}{2}[/tex] is the simplest fraction that cannot be simplified further.
So, any number multiplied by it both on the numerator and denominator will be an equivalent fraction.
Multiplying both the numerator and denominator of the fraction [tex]\frac{3}{2}[/tex] by 4, the resulting fraction is [tex]\frac{12}{8}[/tex].
Hence, the correct options are (A) and (C).

Which radical expression consists of two perfect squares?
A
V16
B
V25
С
125
D
V21
Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
Jamel has a cell phone that has unlimited minutes and texts for $45 a month, but he has to pay $5 for each gigabyte of data he uses. If he does not want to spend more than $65 for his cell phone each month, how many gigabytes can he use?
Answer:
I think it's 4 gigabytes
Step-by-step explanation:
He only wants to pay 65$ and he already spends 45$ on his phone already. So you only have 20 dollars until his grand totaly of 65$ so 5x4= 20 so he can only use 4 gigabytes. Does that make sense? Hope I helped eheh
Brandon is on one side of a river that is 70 m wide and wants to reach a point 250 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s and run at 6 m/s.
Answer:
The minimum amount of time required is 74.7 seconds.
Step-by-step explanation:
The question can be solved in two cases:
i. diagonal swimming of Brandon across the river
ii. Running of the rest distance by Brandon.
Case I: Since he would swim diagonally across the river, then the diagonal distance can be determined by applying appropriate trigonometric function.
Let the diagonal be represented by x, an included angle θ = [tex]45^{o}[/tex] is formed at his starting point (angle formed by the diagonal and the length of the width of the river).
So that:
Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos [tex]45^{o}[/tex] = [tex]\frac{70}{x}[/tex]
x = [tex]\frac{70}{Cos 45^{o} }[/tex]
= 98.995
x = 99 m
The diagonal distance covered by Brandon is 99 m.
The time to cover this distance can be calculated by:
speed = [tex]\frac{distance}{time}[/tex]
time = [tex]\frac{distance}{speed}[/tex]
Given that his swimming rate is 2 m/s, then:
time = [tex]\frac{99}{2}[/tex]
= 49.5
The time taken by Brandon to swim diagonally is 49.5 seconds.
Case II: Since he want to cover a total distance of 250 m;
remaining distance to be covered = 250 - 99
= 151
time = [tex]\frac{distance}{speed}[/tex]
Given that he runs at 6 m/s, then;
time = [tex]\frac{151}{6}[/tex]
= 25.1667
The time taken by Brandon to run the remaining distance is 25.2 seconds.
The minimum amount of time required = time taken by Brandon to swim diagonally + time taken by Brandon to run the remaining distance
= 49.5 + 25.2
= 74.7
The minimum amount of time required is 74.7 seconds.
Minimum amount of time to reach the desired point is 79.5 s
Brandon is on one side of a river
The width of the river = 70 m
Brandon wants to reach a point that is 250 m downstream of opposite side as quickly as possible by swimming diagonally across the river then running the rest of the way.
The swimming speed of Brandon = 2 m/s
The speed of running of Brandon = 6 m/s
Let us consider that the included angle be 45°
[tex]\rm cos \; \theta = \dfrac{70}{x} \\\\cos \; 45 = \dfrac{70}{x} \\\x = \dfrac{70}{0.707} \approx 99[/tex]
So the distance traveled by Brandon in water is 99 m
As the swimming speed of Brandon is given 2 m/s
So the time taken by Brandon to cross the river is given as follows
[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]
[tex]\rm Time \; to\; cross\; the\; river = \dfrac{99}{2} = 49.5 \; s[/tex]
Let the horizontal distance covered by Brandon by swimming is H
So from Pythagorean theorem we can write
[tex]\rm H = \sqrt{99^2 -70^2 } = 70[/tex]
The distance that is left to be traveled by running is 250 - 70 = 180 m
So Time taken in running to reach the point by running = 180/6 = 30 s
So the time to reach the desired point = 49.5 + 30 = 79.5 s

What is the slope and equation of a line perpendicular to the y-axis passing through point (–5, –3)?
Answer:
Slope: m = 0
Equation: y = -3
Step-by-step explanation:
A line perpendicular to the y-axis always has a slope of 0. Slope is calculated by (y2-y1)/(x2-x1) or rise/run or delta y/delta x (they're all the same thing, delta means difference and is notated with a triangle). When there is no change in y (perpendicular to the y-axis), no matter what the change in x is, the slope will be 0.
Since it is given that one of the points has a y-value of -3, the equation for this line would be y = -3. The formula for a linear equation is y=mx+b. Since the slope is 0, the value of mx is 0, and therefore not needed in the equation. b represents the y-intercept and in this case would be -3.
