Find the smallest perimeter and the dimensions for a rectangle with an area of 169 in2. Question content area bottom Part 1 The smallest perimeter for a rectangle with an area of 169 in2 is enter your response here in.
The smallest perimeter and dimensions of rectangle having area of 169 [tex]inches^{2}[/tex] is 52 inches , length 16 inches and breadth also 16 inches.
Given that the area of rectangle is 169 [tex]inches^{2}[/tex].
We have to find the smallest perimeter and dimensions of the rectangle.
let the length of rectangle be x inches and breadth be y inches.
We know that area of rectangle is the product of its length and breadth. So,
Area=xy
169=xy
y=169/x
Perimeter of rectangle =2(x+y)
Put the value of y=169/x in the perimeter.
P=2(x+169/x)
P=2x+338/x
Differentiate both sides with respect to x.
dP/dx=2-338/[tex]x^{2}[/tex]
Again differentiate it with respect to x.
[tex]d^{2} P/dP^{2}[/tex]=676/[tex]x^{3}[/tex]
Because the second derivative is greater than 0 so the perimeter is minimum.
Put dP/dx=0 to get the value of x.
dP/dx=0
2-338/[tex]x^{2}[/tex]=0
2=338/[tex]x^{2}[/tex]
[tex]x^{2}[/tex]=169
x=[tex]\sqrt{169}[/tex]
x=13
Put the value of x in y=169/x
y=169/13
=13
To calculate the perimeter, put the values of x and y in P=2(x+y)
P=2(13+13)
=2*26
=52 inches.
Hence The smallest perimeter and dimensions of rectangle having area of 169 [tex]inches^{2}[/tex] is 52 inches , length 16 inches and breadth also 16 inches.

Depending on the number of teams, the possible numbers of students per team are in the set:
{2, 3, 4, 6, 9, 12, 18}
How many students can be on each team?
We know that there are 36 students divided equally into N teams.
Such that the number of teams is larger than 1 and smaller than 20.
Then we could have 2 teams, such that the number of students in each team is given by the quotient between the total number of students and the number of teams.
36/2 = 18
There are 18 students in each team.
Notice that the numbers of teams can only be factors of 36, where:
36 = 6*6 = 2*2*3*3
So the factors are:

which rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their probabilities
The multiplicative rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their probabilities.
What is the multiplicative rule?The multiplication rule is a method for calculating the likelihood of two events occurring at the same time (this is also one of the AP Statistics formulas). There are two rules for multiplication. P(A B) = P(A) P(B|A) is the general multiplication rule formula, while P(A B) is the specific multiplication rule (A and B).The multiplication rule is the multiplication of one event's probability by the likelihood of another occurrence. The law of independent assortment, Mendel's second law, stipulates that alleles of one gene segregate into gametes independently of alleles of another gene.Therefore, the multiplicative rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their probabilities.

( You are supposed to get a quadratic equation and then solve that, but I don't know how to get to it.)
Using the together rate, it is found that it would take each person working individually 27 and 29 hours to paint the house.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, we have that the rates are given as follows:
The together rate is 1/14.The separate rates are 1/d and 1/(d-2).Hence:
[tex]\frac{1}{d} + \frac{1}{d - 2} = \frac{1}{14}[/tex]
[tex]\frac{d - 2 + d}{d(d - 2)} = \frac{1}{14}[/tex]
d² - 2d = 28d - 28.
d² - 30d + 28 = 0
(d - 29)(d - 0.96) = 0.

What is the point slope equation of a line with slope -3 that contains the point (-8,-4)?
Answer:
y = -3x - 28
Step-by-step explanation:
y = mx + b is the slope-intercept of a line. To write an equation in this form. I need to find the slope (m) and the y-intercept (b). Yay! They gave us the slope (m). It is -3. Now we just need to figure out the y. We can do that by plugging in the slope (-3) and using the x (-8) and the y (-4) that they gave us from the point to solve for b.
y = mx + b
-4 = -3(-8) + b Multiple -3(-8) Remember a negative times a negative is a positive.
-4 = 24 + b Now subtract 24 from both side of the equation
-28 = b Now we can write the equation
y = mx + b
y = -3x + (-28) or y = -3x -28. Adding a negative is the same as subtracting a positive.

Create a linear equation for the following data:
Answer:
[tex]y = -3x+4[/tex]
I hope this helps and that you can give a brainliest!
Step-by-step explanation:
Step 1: Rate of ChangeA linear equation means that the y value changes at a constant rate as x increases by 1.
To find the rate of change you need to plug 2 ordered pairs into the formula:
[tex]\frac{y1-y2}{x1-x2}[/tex]
(x1,y1) can be any data point on this table. To make it easy, we will make it (2,-2).
(x2,y2) can be any data point other than the previously chosen point. So, we will choose (-1,7).
If we substitute this into the formula, previously mentioned, we get:
[tex]\frac{-2-7}{2-(-1)}[/tex]
When we solve this, we get the rate of change as -3.
This will be the "m" value in the linear equation format:
"y = mx+b"
The b value is the y-value of the data when x = 0.
So to get the b-value, you need to plug in one ordered pair into the "y=mx +b" equation.
"m" was the rate of change, which we found in the previous step.
Let's use (2,-2) as the chosen ordered pair.
By substitution, we end up with:
[tex]-2=-3(2)+b[/tex]
If we solve this out, we get:
[tex]b = 4[/tex]
m was -3 and b is now 4.
So, putting this into the equation "y = mx+b"
We get our answer as [tex]y=-3x+4[/tex].

How many 2 digit numbers are the product of two different primes
Answer:
30.
Step-by-step explanation:
2 digit Numbers which have factor of 2:
2*3, 2*5, 2*7, 2*11, 2*13, 2*17, 2*19, 2*23, 2*29, 2*31, 2*37, 2*41, 2*43, 2*47.
That's 14.
Then there are the ones with factor 3:
3*5 ....... 3*31 = 9 numbers.
Then
5*7 to 5*19 = 5 numbers.
7*11 , 7*13 = 2 numbers.
Total is 14 + 9 + 5 + 2
= 30.
There are 30 2-digit numbers that are the product of two different primes.
To determine the number of 2-digit numbers that are the product of two different primes, we first need to identify the primes within the range of 10 to 99. The prime numbers within this range are 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.
To find the count of 2-digit numbers that are the product of two different primes, we can consider all possible pairs of these primes.
The numbers that yield 2-digit numbers with a multiple of 2 are:
(2, 5), (2, 7), (2, 11), (2, 13), (2, 17), (2, 19), (2, 23), (2, 29), (2, 31), (2, 37), (2, 39), (2, 41), (2, 43), (2, 47).
Total = 14
The numbers that yield 2-digit numbers with a multiple of 3 are:
(3, 5), (3, 7), (3, 11), (3, 13), (3, 17), (3, 19), (3, 23), (3, 29), (3, 31).
Total = 9
The numbers that yield 2-digit numbers with a multiple of 5 are:
distinct: (5, 7), (5, 11), (5, 13), (5, 17), (5, 19).
Total = 5
The numbers that yield 2-digit numbers with a multiple of 7 are:
Distincts: (7, 11), (7, 13)
Total = 2
Therefore, the total numbers of pairs are 14 + 9 + 5 + 2 = 30.
