0.8333 and 0, which of these are are rational numbers? Please explain in the space below.
Answer:
0 is the rational number
Step-by-step explanation:
Yes, 0 is the rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer.
Answer:
I think 0.8333
Step-by-step explanation:
a rational number has decimals which terminate or repeat,so 0.8333 has decimals which are repeating

An equation is given A =
4 π r^2
Answer:
D
Step-by-step explanation:
A = 4 π r^2
A/(4π) = r^2
r = sqrt(A/(4π))
Answer:
D
Step-by-step explanation:
Given
A = 4πr² ( divide both sides by 4π )
[tex]\frac{A}{4\pi }[/tex] = r² ( take the square root of both sides )
[tex]\sqrt{\frac{A}{4\pi } }[/tex] = r → D

4. A dirt bike requires 15 L of gas to be mixed with 4 L of oil. If you use 20 L of gas, need?
Answer:
Read down below :)
Step-by-step explanation:
Rather than taking it on and overthinking it the way everyone else does, do it the simple way, like this:
15/3 = 5, right? and 5, when multiplied by 4, becomes 20, right? So divide 4 by 3, and then take that number, and muliply it by 4.
Like this: (4 / 3) * 4, and then you know that 5 L of gas requires 1.33e L of oil. So, like 5*4 = 20, so is 1.33e *4, the amount of oil in 20 L. In all, the answer is 5.33e, or [tex]5 \frac{3}{5}[/tex] or whatever your answer might have to be

You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.
Given:
Of the 50 flips, the coin landed on heads 30 times.
To find:
The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.
Solution:
We have,
Total number of trials = 50
Total number of heads = 30
The experimental probability of flipping heads is:
[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]
[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]
[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]
[tex]\text{Experimental probability}=0.6[/tex]
A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:
[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]
[tex]\text{Theoretical probability}=0.5[/tex]
Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

The fifth term of the expression (n + 3)⁶ is 1,215n².
What is binomial theorem?An expression that has been raised to any finite power can be expanded using the binomial theorem. A useful expansion technique with applications in probability, probability theory, and algebra is the binomial theorem.
The given expression is,
(n + 3)⁶.
To find the fifth term in the expression,
Use binomial expansion method,
[tex](x+y)^n = ^{n}C_0 x^nny^0 + ^nC_1 x^{n-1}y^1 + ^nC_2 x^{n-2} y^2 + ...[/tex]
Use the binomial formula for expression (n + 3)⁶,

manuela wants to make a cube from construction paper . if she cuts out the design below and folds it to make a cube , what will be the surface area of the cube?
25 cm2
70 cm2
125 cm2
150 cm2
Answer:
150 cm2
Step-by-step explanation:
one square would simply be base x height our base is 5 and height is 5 so i multiply that and get 25 since this is a cube all sides are equal so I will simply just multiply 25 by the number of sides since a cube has 6 sides our equation to get the answer would be 25 x 6 = 150 so 150 is our answer!

If the cost of 4 1/2litres of milk is 89 1/2rupees, find the cost of 1 litre of milk. Pls explain too
Answer:
x=19.88
Step-by-step explanation:
Okay, let's try and create a "table" of what we know, and what we are looking for.
4.5 litres of milk cost 89.5 rupees
1 litre costs x rupees
Obviously, we are looking for x.
The method I'm about to tell you, might be familiar. Imagine that there was a giant X where the words cost and costs are above. There'd be a line connecting 4.5 litres of milk with the rupees we are looking for, and another line connecting 1 litre with the 89.5 rupees.
If we were to form an equation to solve for x, we'd put the connecting terms together, with an "=" between them, so we'd have this:
4.5*x=1*89.5
That's our equation, so let's solve for x.
x=89.5/4.5 => x=19.88 , let's say 20 rupees

Answer:
The total number of stamps that Tom collect at the end of X weeks is
[tex]32 + 8 * X[/tex]
Step-by-step explanation:
Complete question
Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.
Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.
Write an equation to represent the number of stamps in Tom’s collection based on the number of weeks he has been collecting stamps.
Solution
Let "X" be the number of weeks for which Tom collected the stamps
The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]
It is given that he collects 8 stamps per week
So the total number of stamps that Tom collect at the end of X weeks is
[tex]32 + 8 * X[/tex]

What is the volume of the trapezoidal prism with a height of 10 cm, base lengths of 3 and 4 cm, base height of 2 cm?
Given:
Height of a trapezoidal prism = 10 cm
Base lengths are 3 and 4 cm.
Base height = 2 cm
To find:
The volume of the trapezoidal prism.
Solution:
Base area of a trapezoidal prism
[tex]B=\dfrac{a+b}{2}\times h[/tex]
Where, a,b are base lengths and h is the base height.
Putting [tex]a=3,b=4,h=2[/tex], we get
[tex]B=\dfrac{3+4}{2}\times 2[/tex]
[tex]B=7[/tex]
The volume of a trapezoidal prism is:
[tex]V=Bh[/tex]
Where, B is the base area and h is the height of the prism.
Putting [tex]B=7,h=10[/tex], we get
[tex]V=7\times 10[/tex]
[tex]V=70[/tex]
Therefore, the volume of the trapezoidal prism is 70 cubic cm.

2. Mercury High School is requiring students to purchase parking permits this year in order to
use campus parking lots. It costs the school a one-time fee of $500 to have the logo
designed. It also costs $2 per permit to print and cut out each one. They expect the average
cost of each permit to be $6.
a. Write a rational equation that describes the situation above.
b. How many parking permits does Mercury High School need to sell in order for the
average cost of a student's parking permit to be $6? Solve your equation from part (a)
to answer the question. Justify your solution as it relates to the context.
Answer:
a. $6 = ($500 + $2q) / q
b. 125
Average cost = ($500 + $2q) / q
($500 + $2x 125) / 125 = $6
Step-by-step explanation:
Average cost = total cost / quantity produced
total cost = fixed cost + variable cost
Fixed costs are costs that do not vary with output. e.g. the cost of the logo
Variable costs are costs that vary with production e.g. cost of printing and cutting
Variable cost = $2 x quantity of parking ticket sold
let q = quantity of parking ticket sold
variable cost = 2q
$6 = ($500 + $2q) / q
to determine the number of parking ticket to be sold for average cost to be $6, take the following steps
Multiply both sides of the equation by q
6q = 500 + 2q
collect like terms
6q - 2q = 500
4q = 500
q = 125
125 tickets have to be sold for average cost to the $125
to justify the answer, replace 125 in the first equation to confirm if $6 would gotten as the average cost
($500 + $2q) / q
($500 + $2x 125) / 125 = $6
