What are Irrational Numbers ?
The real numbers that can be represented as a nonrepeating or a nonterminating decimal but not as a fraction, and the decimal that goes on forever without repeating.
For Example : [tex]\sqrt{2} , \sqrt{5} , \sqrt{7}[/tex] are few example of irrational numbers .
In simpler words : the irrational number is a number that is not rational. which means It is a number which cannot be written as a ratio of two integers or cannot be written as fraction.

Using multiplication as a mathematical operator, Kareem will 864 more cards and Nicole will get 24 more cards
What is MultiplicationMultiplication is a mathematical operation that involves multiplying two or more numbers together. It is one of the four basic operations in mathematics, along with addition, subtraction, and division.
In this problem, we may require the use of some mathematical operators to find the solution to the problem.
1.
He currently has 216 cards, but he needs 15 sets of cards.
1 set of card = 72 cards
Let's calculate the number of sets he currently has.
1 set of card = 72 cards
x set = 216 cards
cross multiply both sides and solve for x.
x * 72 = 216 * 1
x = 216 / 72
x = 3 sets
He currently has 3 sets of cards.
Since he wants 15 sets of cards, we will need 12 more set of cards.
The number of cards can be calculated by multiplying 12 by 72
Number of cards = 12 * 72 = 864
He needs 864 more cards.
2.
1 set of card = $27
1 set = 72 cards
But she's bringing $9 to join, we can calculate the ratio of cards she will get.
1 / 27 = x / 9
x = 9 / 27
x = 1/3
She will get 1/3 of the cards bought which will be
72 * 1/3 = 24 cards
She will get 24 cards

The height of the apple trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.2 feet what percentage of the apple trees are taller than 14.9 ft
Answers
Answer:
2.275%
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 14.9 ft
μ is the population mean = 12.5 ft
σ is the population standard deviation = 1.2 ft
We are to find the percentage of the apple trees are taller than 14.9 ft,
This means x > 14.9, x greater than 14.9
Hence,
z = (14.9 - 12.5)/1.2
z = 2
Probability value from Z-Table:
P(x<14.9) = 0.97725
P(x>14.9) = 1 - P(x<14.9) = 0.02275
Converting to Percentage
= 0.02275 × 100
= 2.275%
Therefore, the percentage of the apple trees that are taller than 14.9 ft is 2.275%

If y varies directly as x, and y = 15 when x = 10, then what
is y when x = 6
Answers
Answer:
y = 9.
Step-by-step explanation:
y = kx where k is a constant.
Substituting the given values:
15 = k*10
k = 15/10 = 1.5 so
y = 1.5x is the relation.
When x = 6
y = 1.5 * 6
= 9..
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
y = kx
k = 1.5 and x = 6
The value of y when x = 6 is 9.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
3x = 5 is an equation.
We have,
If y varies directly as x.
This means,
y ∝ x
y = kx
where k is the constant of proportionality.
Now,
y = 15 when x = 10
This means,
15 = 10k
k = 15/10
k = 1.5
Now,
y = kx
k = 1.5
x = 6
y = 1.5 x 6
y = 9
Thus,
y = kx
k = 1.5 and x = 6

Answer:
[tex]-3/\sqrt{58}[/tex]
Step-by-step explanation:
tan = opposite / adjacent
opposite side is the y-coordinate of a point on the terminal side
adjacent side is the x-coordinate of a point on the terminal side
if the terminal side is in the second quadrant (the top-left quadrant), a coordinate on the terminal side would have a negative x-coordinate and a positive y-coordinate
This being the case:
the opposite side (y) would be -3 and the adjacent side (x) would be 7
using the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
[tex]7^2+(-3)^2=c^2[/tex]
The hypotenuse is c, so it equals [tex]\sqrt{58}[/tex]
sin = opposite / hypotenuse
so sin(theta) = [tex]-3/\sqrt{58}[/tex]
The radius of a circle is 6 centimeters. What is the circle's circumference?
Answers
Answer:
37.7 cm
Step-by-step explanation:
C=2πr=2·π·6≈37.69911
Answer:
37.68 cm.
Step-by-step explanation:
The formula for circumference of a circle is: πd (diameter)
The radius of this circle is 6 centimeters.
To find the diameter, multiply the radius by 2.
6 × 2 = 12.
12 is the diameter.
Lastly, multiply the diameter by pi.
**3.14 IS A SUBSTITUTE FOR PI**
3.14 = 37.68.
Therefore, the circumference of this circle is 37.68 cm.
A rescue boat just picked up some sailors in a lifeboat. Now the rescue boat is heading north at 14 miles per hour. The lifeboat, which they abandoned, is drifting south at a speed of 3 miles per hour. How long will it be before the rescued sailors are 57 miles from their lifeboat?
Answers
The time it will take for the rescued sailors to be 57 miles from their life boat is given as follows:
3.35 hours.
What is relative velocity?Relative velocity is obtained considering the direction in which the objects are traveling, as follows:
Opposite direction: the relative velocity is given by the sum of the velocities of each object.Same direction: the relative velocity is given by the subtraction of the velocities of each object.For this problem, the sailors and the lifeboat are traveling in opposite directions, hence the relative velocity, considering each of their velocities is given as follows:
v = 14 + 3 = 17 miles.
(meaning that they get 17 miles farther each hour).
Velocity is distance divided by time, hence the time it will take for them to be 57 miles apart is given as follows:
17 = 57/t
17t = 57
t = 57/17
t = 3.35 hours.

All must add up to 360°
100+44=144°
360-144
= 216°
Answer:
144°
Step-by-step explanation:
Every possible triangle's 3 angles add up to 180.
So when you are given 2 angles of a triangle (100° and 44°), you can find the 3rd one by subtracting the given angles from 180°.
100°+44°=144°
180°-144°=36°
That's the missing angle inside the triangle.
We need that to find angle 1 because 2 angles that make up a straight line add up to 180°. So 180-36°=144°.

Answers
The linear equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
The first step to take in order to determine jj, is to determine the total cost of the 5-pack of juice bottles.
Cost of the 5-pack of juice bottles = Total cost before tax - cost of the bag of oranges
Cost of the 5-pack of juice bottles = $7.46 - $2.66 = $4.80
The second step is to determine the cost of each bottle of juice
The cost of each bottle of juice = Cost of the 5-pack of juice bottles / total number of bottles
$4.80 / 5
= $0.96
