Write two fractions that are equal to 1/2.
Answer:
2/4 nd 4/8
Step-by-step explanation:
Extras; 3/6, 5,10, 6/12
Answer:
2/4 and 3/6 .
Step-by-step explanation:
Given :-
A number 1/2.We need to write two fractions which equals to 1/2 . For that we can multiply the denominator and numerator by same number .
First equal fracⁿ :-
[tex]:\implies[/tex] 1/2 × 2/2 = 2/4
Second equal fracⁿ :-
[tex]:\implies[/tex] 1/2 × 3/3 = 3/6
Hence the two equal fractions are 2/4 and 3/6 .Ajay has equal numbers of rock songs and pop songs loaded on his personal music player. He has it set to play songs plz helpp...on a random shuffle. Suppose Ajay is designing a simulation that could be used to estimate the probability that the next three songs to play are all alternative rock songs.
Which simulation design could Ajay use to estimate the probability?
O A. Random digits Let 1, 2, 3, 4,5rock Let 6,7,8,9,0 pop Select three rondom digits. Repeat
O B. Number cube Let 1,2 = rock Let 4,5 - pop Roll cube three times. Repeat
O C. Number cube Let 1 = rock Let 2 = pop Roll cube three times. Repeat
O D. Random digits Let 1,2 = rock Let 3,4,5,6,7,8,9,0 = pop select three digits. repeat
Option D. The simulation design that Ajay can use to estimate the probability would be Random digits Let 1,2 = rock Let 3,4,5,6,7,8,9,0 = pop select three digits. repeat.
How to find the simulation designThe number cube has being said to be made up of six digits. The digits are said to be assigned in pairs of three.
Hence we are going to have a case of 1/3. This is what can then be used to model the probability.

A cylinder has a height of 9 inches. Its volume is 4,775.94 cubic inches l. What is the radius of the cylinder
Answer:
The radius of the cylinder is 13.0 inches.
Step-by-step explanation:
The volume of a cylinder is given by:
[tex] V = \pi r^{2}h [/tex]
Where:
V: is the volume = 4775.94 in³
r: is the radius =?
h: is the height = 9 in
Hence, by solving the above equation for "r" we have:
[tex] r = \sqrt{\frac{V}{\pi h}} = \sqrt{\frac{4775.94 in^{3}}{\pi 9 in}} = 13.0 in [/tex]
Therefore, the radius of the cylinder is 13.0 inches.
I hope it helps you!

Answer:
80
Step-by-step explanation:
18^2 + 80^2 = 82
324 + 160 = c^2
Answer:
80 cm
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem which is a^2 + b^2 = c^2. We are given that a = 18, and c as the hypotenuse equals to 82. We can plug these numbers into the theorem:
18^2 + b^2 = 82^2
324 + b^2 = 6724
b^2 = 6400
b = 80 cm
Math grade 9, can anyone solve it
Answer:
a) Acceleration = 2.4 m per seconds²
b) Distance traveled = 132 m
Step-by-step explanation:
a). Acceleration of an object is defined by the equation,
v = u + at
Here, v = Final speed
u = Initial speed
a = Acceleration
t = Duration Or time
From the graph attached,
Between t = 0 and t = 5 seconds,
v = 12 meter per second
u = 0
t = 5 seconds
B substituting values in the equation,
12 = 0 + a(5)
a = [tex]\frac{12}{5}[/tex]
a = 2.4 m per seconds²
b). Equation representing distance traveled by an object,
v² = u² + 2as
Here, v = Final speed
u = Initial speed
a = Acceleration
s = Distance traveled
By substituting these values in the given equation,
1). Between t = 0 to t = 5 seconds,
(12)² = 0 + 2(2.4)s
s = [tex]\frac{144}{4.8}[/tex]
s = 30 m
2). Between t = 5 to t = 12 sec
Car moved with a constant speed (Acceleration = 0)
Distance traveled = Speed × Time
= 12 × 7
= 84 m
3). Acceleration of the car between t = 12 sec to t = 15 sec
By substituting the values in the equation,
v = u - at
0 = 12 - a(3)
a = 4 meter per seconds²
Distance traveled in this duration,
v² = u² - 2as
0 = (12)² - 2(4)s
144 = 8s
s = [tex]\frac{144}{8}[/tex]
s = 18 m
Therefore, total distance covered by the car = 30 + 84 + 18
= 132 meters

Answer:
0.5
Step-by-step explanation:
To find the rate of change, we can use the slope formula of [tex](y^2-y^1) / (x^2-x^1)[/tex].
Plugging in the first two points gets us:
[tex](1 - .5) / (1-0)[/tex]
[tex]0.5 / 1[/tex]

5. Find the equation of the line passing through
the point
(d) (2, -3) and perpendicular to the line y + 2x = 13.
y = (1/2)x - 4
Step-by-step explanation:
The equation of the given line is
y = -2x + 13
The equation of the perpendicular line that we need must have a slope of 1/2 and passes through (2, -3) so the form should be
y = (1/2)x + b
To solve for b, use the point (2, -3)
-3 = (1/2)(2) + b ---> b = -4
Therefore, the equation that we need has the form
y = (1/2)x - 4

What is Limit of g (x) as x approaches 1, if it exists?

7,000,000
700,000,000
DNE
Answer:
7,000,000
Step-by-step explanation:
Limit of a function:
The limit of a function is finding looking at it's lateral limits.
If the lateral limits are equal:
The limit exists.
[tex]\lim_{x \rightarrow a} f(x) = \lim_{x \rightarrow a^{+}} f(x) = \lim_{x \rightarrow a^{-}} f(x)[/tex]
If lateral limits are different:
That is:
[tex]\lim_{x \rightarrow a^{+}} f(x) \neq \lim_{x \rightarrow a^{-}} f(x)[/tex], then the limit does not exist.
In this question:
To the left of 1, that is, 0.9999....
[tex]\lim_{x \rightarrow 1^{-}} g(x) = 7,000,000[/tex]
To the right of 1, that is, 1.0001...
[tex]\lim_{x \rightarrow 1^{+}} g(x) = 7,000,000[/tex]
Since the both limits are the same, the limits exists and it's value is of 7,000,000.
