Answer:
ummmm j?:)
Step-by-step explanation:
(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number
(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.
Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.
Real numbers are formed by the union of rational and irrational numbers.

Which number below is irrational?
A. 3 √ 8
B. 3√ 125
C. √ 49
D. √ 52
Answer:
D. √ 52 = 2 * √ 13 irrational
Step-by-step explanation:
A. 3 √ 8 = 2 rational
B. 3√ 125 = 5 rational
C. √ 49 = 7 rational
D. √ 52 = 2 * √ 13 irrational
Answer:
The irrational number is [tex]\sqrt{52}[/tex].
Step-by-step explanation:
An irrational number is a non-terminating decimal number that does not follow any specific pattern (example: 0.333.... and 16.111... are all repeating with 3s and 1s, making them rational. While [tex]\sqrt{3}[/tex] or [tex]\sqrt{5}[/tex] are continuing decimals without a pattern, making them irrational). [tex]\sqrt[3]{8}[/tex], [tex]\sqrt[3]{125}[/tex], and [tex]\sqrt{49}[/tex] are all rational numbers, as they are equivalent to 2, 5, and 7 respectively. [tex]\sqrt{52}[/tex] can be written as [tex]\sqrt{4*13}[/tex] or [tex]2\sqrt{13}[/tex], since [tex]\sqrt{13}[/tex] is not a complete square root, which means that [tex]2\sqrt{13}[/tex] is an irrational number.

A sapling that started out 13.63 inches tall grew 2.41 inches per year. How tall was the sapling when it was 14 years old?
Answer:
47.37 Inches
Step-by-step explanation:
We start by assuming that we're at zero years when the tree is at 13.63 inches. We then ignore that height, and look at the rate of growth, which is 2.41 in / year.
The question asks how tall the tree is when it's 14 years old, so we multiply 2.41 inches / year by 14 years to get 33.74 inches.
The final step is to add that 33.74 onto the original 13.63 to get a new total of 47.37 inches when the sapling is 14 years old.
3. (5 points) A company wishes to estimate the mean monthly electric bill. If the standard
deviation is $400, how large a sample is required to estimate the mean electric bill to within $100
with 98% confidence?
Answer:
9.304
Step-by-step explanation:
company wishes to estimate the mean monthly electric bill. If the standard
deviation is $400, how large a sample is required to estimate the mean electric bill to within $100
with 98% confidence?
Sample size, n = (Zcritical * σ) ÷ ME
σ = standard deviation ;
ME ≥ margin of error
α = 98% ; At 98% confidence level ;Zcritical = 2.326
n ≥ (2.326 * 400) / 100
n ≥ 930.4 / 100
n ≥ 9.304
n = 10

The function H =f(t) gives the temperature, HF, of an object t minutes after it is taken out of the refrigerator and left to sit in a room. (a) Write a new function in terms of f (0) for the temperature if the object is taken out of the refrigerator 2 minutes later. Note that·H =" is already provided. Do not include this in your submitted response to this question. b) Write a new function in terms of f(0) for the temperature if both the refrigerator and the room are 15 F colder. Note that·H-e is already provided. Do not include this in your submitted response to this question.
(a) The value of the function after 2 minutes later will be [tex]H=(T)^{t+2}[/tex].
(b) The value of the function at 15 F will be [tex]H=(15)^t[/tex].
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the function H =f(t) gives the temperature, HF, of an object t minutes after it is taken out of the refrigerator and left to sit in a room.
(a) The value of the function after 2 minutes will be,
[tex]H=T^t\\H=(T)^{t+2}[/tex]
(b) The value of the function at 15 F will be,
[tex]H=(15)^{t}[/tex]
Therefore, the value of the function after 2 minutes later will be [tex]H=(T)^{t+2}[/tex]. The value of the function at 15 F will be [tex]H=(15)^t[/tex].

The following data points represent the number of chicken nuggets on each family member's plate.
1,3,0, 6, ?
If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.
nuggets
Answer:
The missing number of chicken nuggets is 5.
Step-by-step explanation:
To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.
Like this,
1 + 3 + 0 + 6 = 10
10 / 4 = 2.5
There are 4 present numbers in this data set, and one is missing.
Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.
Because,
1 + 3 + 0 + 6 + 5 = 15
15 / 5 = 3
Therefore, 5 is the missing number of the data set.

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.
Answer:
a = 1.4 and d = 6.9
Step-by-step explanation:
To get the value of d and a, we will use the SOH CAH TOA identity
For the first tringle;
Opposite = d ((opposite angle 60 degrees)
Adjacent = 4
Tan theta = opp/adj
Tan 60 = d/4
d = 4tan60
d = 4(1.732)
d = 6.9
For the second triangle;
Opposite = a
Hypotenuse = 2
Since sin theta = opp/hyp
Sin45 = a/2
a = 2sin45
a = 2(0.7071)
a = 1.4
Hence a = 1.4 and d = 6.9

Rachel's car has a 12 gallon gas tank and
she uses about 0.5 gallons per day driving to
school. Write an equation describing the
number of gallons of gas, g, Rachel has in
her car and the number of days, d, she has
driven to school.
please help meeee
Answer:
g=dx
Or, if you'r wanting the solved equation..
12 = 0.5 x 24
Step-by-step explanation:
If she has 12 gallons in her tank and you look at what it's asking us to do, "..number of gallons of gas, g" pairs up with the 12 gallons while the 0.5 gallons used per day pairs with "...the number of days, d, she has driven to school."

Following are the responses to the given question:
Step-by-step explanation:
[tex]\angle C= 180 - ( 26 + 51 )\\\\C = 103^{\circ}[/tex]
applying the law of sines to find the unknown sides:
[tex]\to \frac{a}{\sin A} = \frac{c}{\sin C}\\\\\to \frac{a}{\sin 26} = \frac{28}{\sin 103}\\\\a=\frac{28 \times \sin 26 }{\sin 103}\\\\a=\frac{28 \times 0.438371147 }{0.974370065}\\\\a=\frac{12.2743921 }{0.974370065}\\\\a=12.597259\\\\a=12.59\\\\a = 12.6 \ m\\\\[/tex]
[tex]\to \frac{b}{\sin 51} = \frac{28}{\sin 103}\\\\\to b=\frac{28 \times \sin 51 }{\sin 103}\\\\b=\frac{28 \times 0.777145961 }{0.974370065}\\\\b=\frac{21.7600869 }{0.974370065}\\\\b=22.3324681\\\\b=22.3\\\\b = 22.3 \ m\\\\[/tex]
so,
[tex]\angle C = 103^{\circ}\\\\\to AC = 22.3\ m\\\\\\to BC = 12.6 \ m[/tex]
