1/3 of a cup of milk each time she makes a batch of pancakes how many batches can she make if she only has 11/12 of a cup of milk left
Answer:
She can make [tex]\frac{33}{12}[/tex] batches.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
We have that:
For each batch of pancakes, 1/3 cups of milk are needed. Now, she has 11/12 cups of milk, so how many batches can she make?
1 batch - 1/3 cups
x batches - 11/12 cups
Applying cross multiplication:
[tex]\frac{x}{3} = \frac{11}{12}[/tex]
[tex]12x = 33[/tex]
[tex]x = \frac{33}{12}[/tex]
She can make [tex]\frac{33}{12}[/tex] batches.
Find the value of x
a) 57
b) 60
c) 69
d) 63
Answer:
b
Step-by-step explanation:
The tangent- secant angle 55° is equal to half the difference of its intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (170 - x) = 55 ( multiply both sides by 2 to clear the fraction )
170 - x = 110 ( subtract 170 from both sides )
- x = - 60 ( multiply both sides by - 1 )
x = 60 → b
Find the mean of the data set {4.5,5, 3.5, 2, 2.5}.
So what is the answer ;, I nordeste im
Answer:
Mean = 3.5
Step-by-step explanation:
The given data is :
4.5,5, 3.5, 2, 2.5
We need to find the mean of the given data.
We know that,
Mean = sum of observations/total no. of observations
Here,
Total no. of observations = 5
Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5
Mean,
[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]
Hence, the mean of the data set is equal to 3.5.

Answer:
A more complex question has rarely been asked.
Principia Mathematica took nearly a thousand pages to prove that 1+1=2. It does meander a bit, but had they wanted to prove 1+1=2 alone, it could have done so in 500 pages.
Mathematically speaking, the definition of 1 is:
There exists a number such that when multiplied upon an element of a specified set, yields the element of the specified set.
It is also defined as:
1.0000000000000000000000…
.9999999999999999999999999…
as the set of all singletons.
a singleton is a set with exactly 1 element.
These 4 definitions work in tandem with one another.
For example:
1=1
Divide both sides by 3.
1/3=1/3
Rewrite.
1/3=.33333333333333333...
Multiply both sides by 3.
1=.9999999999999999999...
Similarly:
If =.9999999999999999999...
10=9.99999999999999999...
10=9+.99999999999999...
10=9+
Simplify by subtracting x from both sides.
9=9
=1
.99999999999999999999...=1
As the set of all singletons, 1 is also THE element that represents the set of all single entities.
That is to say: if you have 7 erasers. What you really have is a set of 7 single entities. The definition of 7 becomes: 1 + 1 + 1 + 1 + 1 + 1 + 1; and not as is commonly believed as: 6 + 1.
There is an argument for 7 to be defined as 6 + 1, but this argument is a corollary of the Peano Axioms which in turn argues that there exists a set with absolutely nothing in it {} and a set with exactly something in it {x}. More on this later.
The Principia Mathematica uses Peano's (from the Peano Axioms mentioned earlier) work and notation to expertly slice through the many nuances pertaining to this question.
This is something we will not do; but hopefully, we will also be able to effectively demonstrate why 1 + 1 = 2 in less than 1000 pages.
We will assume these basic principles of number theory:
There exists a number such that when multiplied to an element of a specific set, yields that element of the specific set.
There exists a number such that when added to an element of a specific set, yields that element of the specific set.
If we again assume to have only two sets, a set that is empty: {} containing no elements, and a set that is not empty {x} containing an element. We realize that Consequently, we went from nothing {}, to something {x}. This means that {x} is the successor to {}, as the next step up from nothing, is something.
As such we now have two elements:
Nothing, {}, and something that comes after {}, this something is called the successor, and it is the Successor of nothing.
in written notation we have:
{} and { the Successor of nothing }
Rewritten:
{0, the thing that comes after 0}
Further reworded:
{0, Successor (0) }
Reduced further:
0,(0)
Where S(0) stands in place of ‘the successor’. Further, we know there are an infinite number of possible Natural numbers, and we get:
{0, Successor of 0, the successor of the successor of 0, the successor of the successor of the successor of 0,…}
Further reduced:
0,(0),((0)),(((0))),((((0)))),(((((0)))),…
Further explained:
We know that we had nothing, and added something to it, and got something:
Nothing + Something = Successor of nothing.
0+__=(0)
We also know that there is nothing closer to 0, than the thing that comes after 0.
0+(0)=(0)
This implies that S(0) is the smallest increment possible from natural number to next natural number.
As a consequence, we now have two discovered entities: Something, and Nothing.
Let’s give them names.
We have decided that
Nothing = 0 .
0 = Nothing.
S(0) is the something that comes after nothing.
We define a new symbol: 1, to be: 1 = S(0)
This is to say that 1 IS the symbol that succeeds 0;
We could have drawn any shape to define the number that succeeds 0; we chose to draw a 1.
0+(0)=(0)
0+1=(0)
0+1=1
0,1,((0)),(((0))),((((0)))),(((((0)))),…
We now have definitions for 0, and 1. What about a definition for the thing that comes after one? The successor of 1?
As we know S(0) is the smallest increment available, and we are interested in finding S(0)’s successor we investigate:
The successor to the successor of Nothing:
0+(0)=1;1+(0)=(1)
This reads:
The successor of the successor of nothing IS the successor of one
And now… we need a new symbol.
We define the
(1)=2
The successor of 1 IS 2.
Thus:
0+(0)=1;1+(0)=(1)=2
Simplify:
0+1=1;1+1=(1);(1)=2.
Further:
0+1=1;1+1=2;2=2.
1 has many different properties; but all of the properties and their resulting definitions have little to do with why 1 + 1 = 2. And that 1 + 1 = 2 is a byproduct of properties inherent to Natural numbers.
Step-by-step explanation:
A school has 100 students doing extra lessons 36 students were enrolled in mathematics and English, 4 students were enrolled in both subjects. How many students in an extra lesson that does not do either subject. Explain how you got your answer.
Answer:
60
Step-by-step explanation:
If a school has 100 students doing extra lessons, then;
n(U) = 100
If 36 students were enrolled in mathematics and English. then;
n(MuE) = 36
If 4 students were enrolled in both subjects, then;
n(MnE) = 4
Let n(MuE)' be those that does not do either subject
hence;
n(U ) = n(MuE) + n(MuE)'
100 = 36 + n(MuE)'
n(MuE)' = 100 - 36
n(MuE)' = 64
Since 4 students were enrolled in both, hence (64-4) i.e 60 does not do either subject.

C.P. = Rs400, Loss = 12% , Find S.P
Answer:
Step-by-step explanation:
CP= Rs 400
loss%=12%
let sp be x
SP=CP-loss%*CP
x=400-12/100*400
x=40000-4800/100
x=35200/100
x=352
therefore sp =Rs 352
Answer:
S.P. = ₹352
Step-by-step explanation:
UNITARY METHOD:
If C.P. = ₹100
Then SP = ₹(100-12) = ₹88
If C.P. = ₹1
S.P. = ₹(88/100)
Then, as given: C.P. = Rs 400
S.P. = ₹( 88/100)*400
= ₹352
Therefore, S.P. = ₹352
A classroom has a length of 20ft. And a width of 30ft. The flooring is to be replaced by tiles. If each tile has a length of 24 in and a width of 36 in, how many tiles are needed to cover the classroom?
Answer:
100
Step-by-step explanation:
first we need to turn the feet into inches
20x12=240
30x12=360
now to get the area of the floor we need to do 360x240=

A biologist studying the relationship between tilapia and catfish in a pond finds that the ratio of tilapia to catfish is 6:20. If the pond has 30 catfish, how many tilapia are in the pond?
Answer: 9 tilapia
Step-by-step explanation:
The ratio of 6:20 for tilapia to catfish means that for every six tilapia, there are 20 catfish in the pond.
If there are 30 catfish, use direct proportion to find out the number of tilapia:
6 : 20
x : 30
Cross multiply:
20x = 180
x = 180 / 20
x = 9 tilapia

Tell whether the function table represents a linear or exponential relationship.
Answer: Linear
Step-by-step explanation: When determining whether the function table represents a linear or exponential relationship, we are checking to see if the rate of change is constant or increasing. If we look at the table, when x increases by 1, y increases by 3. This means that on that interval, the average rate of change is 3/1 = 3. When we increase x by 1 again, we see that y increases by 3 again. This means that the rate of change is constant for the function, so it must be linear.
