Let the one's digit be y and tens digit be x,
Number = 10x + y
Then,x=3y⋯(i)
Reversed number = 10y + x
A.t.Q :- (10x+y)−(10y+x)=36 Put x = 3y in eq. (i)
⇒9x−9y=36
⇒x−y=4⋯(ii)
⇒3y−y=4
∴2y=4 x=3y ∴x=6
y=2
∴ Number = 62
3x3=9

Hope this helps :)
a) Ratio of yellow seeds to green seeds = 3:1
b) Ratio of bumpy yellow to smooth yellow to bumpy green to smooth green peapods = 1:3:3:9
What is ratio?A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one.
Given,
a) No. of yellow seeds = 1719
No. of green seeds = 573
Ratio of yellow seeds to green seeds = 1719/573 = 3/1 = 3:1
b) No. bumpy yellow pea pods = 87
No. of smooth yellow pea pods = 261
No. of bumpy green pea pods = 261
No. of smooth green pea pods = 783
Ratio of bumpy yellow to smooth yellow to bumpy green to smooth green pea pods = 87/261/261/783
= 1/3/3/9
= 1:3:3:9
Hence,
a) 3:1 is ratio of yellow to green seeds.
b) 1:3:3:9 is ratio of bumpy yellow to smooth yellow to bumpy green to smooth green peapods.

Here are several function rules. Calculate the output for each rule when you use -6 as the input.
Answers
Answer:
1) -13
2) 36
3) -2
4) -5
5) -6
6) -216
Step-by-step explanation:
The output for the considered rules are: Rule 1: -13, Rule 2: 36, Rule 3: -2, Rule 4: -2, Rule 5: π, Rule 6: 216 cubic cm.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We're given that:
Input = -6Applying all the rules, one by one:
Rule 1: Subtract -7
\(\rm \text{inp}ut -7 = -6 -7 = -13\)
Rule 2: Square the input\(\rm (\text{inp}ut )^2 = (-6)^2 = -6\times -6 = 36\)
Rule 3: Divide by 3\(\rm \dfrac{\text{inp}ut }{3} = \dfrac{-6}{3} = -2\)
Rule 4: Divide the input in 3Dividing something in x parts means that thing divided by x
\(\rm \dfrac{\text{inp}ut }{3} = \dfrac{-6}{3} = -2\)
Rule 5: Write π\(\pi\) (no use of input).These type of functions which always give same constant result, no matter what the input is, are called constant functions.
Rule 6: Volume of cube with side length as input in cm.Volume of a cube is the cube of its side length (raising it with power 3).
We're specified that:
Side length of the considered cube = input = -6 cm
Since length is a non-negative quantity, so we take absolute value of -6, therefore, we have:
side length of the cube = |-6| = 6 cm
Thus, its volume is:
\(V= (\rm side)^3 = 6^3 = 216 \: \rm cm^3\)
Thus, the output for the considered rules are: Rule 1: -13, Rule 2: 36, Rule 3: -2, Rule 4: -2, Rule 5: π, Rule 6: 216 cubic cm.

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answers
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62

A tropical species of mite named Archegozetes longisetosus is the record holder for the strongest insect in the world. It can lift up to 1.182 × 103 times its own weight. If a person who weighed 100 pounds were as strong as this insect, how much could that person lift? Enter the answer using scientific notation.

The first thing we have to do is to measure your weight using a weighing scale.
Suppose your weight is 130 pounds, therefore you can lift:

A baseball team averages one win to every one loss. Use a simulation to find each experimental probability for three games.
P(1 win and 2 losses) and P(three losses)
Answers
Answer: I think it's P(1 win and 2 losses)
Step-by-step explanation: That is most accurate because there are 3 games, and you can't split 3 in half. (Well you can but then it would equal 1.5 and you can't win or lose a game 1.5 to 1.5). So splitting 3 is most accurate if you do 2 for 1 and 3 for another.
Hope this helps : D
Simulating three games:
- HHT: 2 wins and 1 loss
- HTH: 2 wins and 1 loss
- THH: 2 wins and 1 loss
- TTH: 1 win and 2 losses
- THT: 1 win and 2 losses
- HTT: 1 win and 2 losses
- TTT: 3 losses
The experimental probability of getting 1 win and 2 losses is 3/8 or 0.375.
The experimental probability of getting 3 losses is 1/8 or 0.125.

Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;

= -15
Now, take any of the given points and substitute the values

We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26

Step by step explanation
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
