The simplified form of the expression is determined as (3.82)²²³ x 10¹⁷⁸⁴.
What is the simplification of the expression?To simplify a mathematical expression is to represent it in the least complicated form possible.
In general the simplest form is one that has used the fundamental properties of numbers, exponents, algebraic rules, etc. to remove any duplication or redundancy from the expression.
The given expression;
(11,234 x 34,002 + 2,332/304,002)²²³
The simplification of the expression is determined as follows;
= (3.82 x 10⁸ + 7.67 x 10⁻³)²²³
= (3.82 x 10⁸)²²³
= (3.82)²²³ x 10¹⁷⁸⁴
Thus, the simplified expression of (11,234 x 34,002 + 2,332/304,002)²²³ is determined as (3.82)²²³ x 10¹⁷⁸⁴.

Given AC=DF,BC=DE
Prove AB=EF
Answer:
Hope this helps
Step-by-step explanation:
AC=DF
AB+BC=DE+EF
*BC=DE*
AB+DE=DE+EF
AB=EF
AB = EF can be proved by using the following from the given figure:
- AB + BC = AC
- DE + EF = DF
- AC = DF
- BC = DE
Given,
AC = DF
BC = DE
We need to prove AB = EF.
What does it mean to have a point between two points in a line?If there is a point in between two points of a line:
M________N______________0
MN + N0 = MO
We have,
A_________B______C
D____E___________F
Now,
Putting the condition of a point between two points.
We get,
AC = AB + BC _____(1)
DF = DE + EF ______(2)
Prove AB = EF.
From (1) and (2)
AC = AB + BC _____(1)
DF = DE + EF ______(2)
And,
AC = DF ______(3)
This means (1) = (2)
AB + BC = DE + EF ______(4)
BC = DE ______(5)
From (5), (4) can be written as:
AB + BC = BC + EF ______(6a)
or
AB + DE = DE + EF _____(6b)
Cancel out the common from both sides.
We get,
AB = EF
Thus using the equation (1), (2), (3), (4), and (5) we can prove AB = EF.

Sarah pulls a card from a standard deal and then replaces it she does this 30% times and 40% of the time it is hearts what is the probability that she does not get hearts
Answer:
60% chance it is not hearts.
Step-by-step explanation:
100%-60%=40%
The probability that Sarah does not get hearts is 60%.
Given that, Sarah pulls a card from a standard deal and then replaces it she does this 30 times and 40% of the time it is hearts.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Total number of outcomes = 30
P(Hearts) = 40% =0.4
Number of times heart occur = 40% of 30
= 0.4 × 30
= 12
Number of times heart does not occur = 30-12=18
Probability of heart does not occur = 18/30
=3/5
=0.6 × 100
=60%
Therefore, the probability that Sarah does not get hearts is 60%.

If 120 miles is 4 hours then the number of hours for 225 miles is 7.5 hours.
Given,
120 miles = 4 hours
We need to find how many hours for 225 miles.
How to compare the given two units?We need to find the unit rate of the given two units.
And multiply the required value on both sides.
Example:
2 hours = 120 minutes
Find how many minutes in 5 hours.
We will find the unit rate of:
- 2 hours = 120 minutes
- 1 hour = 60 minutes
Multiply 5 on both sides
- 5 x 1 hour = 5 x 60 minutes
- 5 hours = 30 minutes.
Find the number of hours in 225 miles.
We have,
120 miles = 4 hours
Find the unit rate by dividing both sides by 120.
1 mile = 4/120 hours
Multiply 225 on both sides.
225 x 1 mile = 225 x 4/120 hours
225 miles = 7.5 hours
Thus if 120 miles is 4 hours then the number of hours for 225 miles is 7.5 hours.

b) Find the original cost of a digital camera, if 13% VAT is levied on it and a payment of Rs. 20,905 is made.
Answer:
The original cost of the digital camera is Rs. 18,500.
Step-by-step explanation:
Let c be the original cost of the digital camera
Since VAT of 13% was added then we can say that the amount that was paid was 13% more than the original price. So the payment made was 113% of the original amount or 1.13 in decimal
Payment = original cost + 13% VAT
20, 905 = c + 0.13c
20, 905 = 1.13c
Divide both sides of the equation by 1.13
20905/1.13 = 1.13c/1.13
18,500 = c
c = Rs. 18,500

When is a fraction in its simplest form?A fraction is said to be in its simplest form when the numerator and the denominator of the fraction are co-prime to each other. Co-prime means that they don't have any common factor between them except 1.
How do we solve the given question?We are given the fractional expression (2/2)(7/18).
We first perform the given multiplication to us:(2/2)(7/18) = (2*7)/(2*18) = 14/36
Now, we write the numerator and denominator as a product of their prime factors.
14/36 = (2*7)/(2*2*3*3).
We cancel the common terms from the numerator and the denominator.
∴ 14/36 = (7)/(2*3*3) = 7/18
.∴ The simplified form of the given expression 2/2·7/18 is 7/18.

Question number 8. Prove that 3 + √5 is an irrational number.
Answer :
Let's assume the opposite of the statement i.e., 3 + √5 is a rational number.
[tex] \\ \sf \: 3 + \sqrt{5} = \frac{a}{b} \\ \\ \qquad \: \tiny \sf{(where \: \: a \: \: and \: \: b \: \: are \: \: integers \: \: and \: \: b \: \neq \: 0)} \\ [/tex]
[tex] \\ \sf \: \sqrt{5} = \frac{a}{b} - 3 = \frac{a - 3b}{b} \\ [/tex]
Since, a, b and 3 are integers. So,
[tex] \\ \sf \: \frac{p - 3b}{b} \\ \\ \qquad \tiny \sf{ \: (is \: \: a \: \: rational \: \: number \:) } \\ [/tex]
Here, it contradicts that √5 is an irrational number.
because of the wrong assumption that 3 + √5 is a rational number.

Hence, 3 + √5 is an irrational number.

What is the explicit rule for the arithmetic sequence shown in the graph?
The explicit rule for the sequence in the graph is f(n) = 9.5 + 2(n - 1)
Finding the explicit rule for the sequenceFrom the question, we have the following parameters that can be used in our computation:
The graph
In the graph, we can see that 2 is added to the previous term to get the new term
This means that
First term, a = 9.5
Common difference, d = 2
The nth term is then represented as
f(n) = a + (n - 1) * d
Substitute the known values in the above equation, so, we have the following representation
f(n) = 9.5 + 2(n - 1)
Hence, the explicit rule is f(n) = 9.5 + 2(n - 1)
