The number of significant digits the product should have = 2
The given numbers are:
[tex]4.5160 \times 10^{-3}\\ 2.09 \times 10^7\\ 5.8 \times 10^3[/tex]
We first multiply them.
[tex]4.5160 \times 10^{-3}\times 2.09 \times 10^7\times 5.8 \times 10^3 = 54.743\times10^7[/tex]
In measurement problems, we usually write it as [tex]5.474\times10^7[/tex]
Significant digits are the numbers which decide the precision and accuracy in measurement problems.
The fewest number of significant digits in each factor of multiplication is considered as the significant digits of the product.
So number of significant digits in [tex]4.5160\times10^{-3}[/tex] = 5
Number significant digits in [tex]2.09\times10^7[/tex] = 3
Number of significant digits in [tex]5.8\times10^3[/tex] = 2
So the product should be rounded into 2 significant digits.
So the product, [tex]5.474\times10^7[/tex]= [tex]5.5\times10^7[/tex] with 2 significant figures.

The solution of expression is 8log6.
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
According to the problem, we will use some of the basic logarithmic properties,
We have been given that expression as
⇒ log6⁸ + 2log6³ + log6¹² - log6²⁴
[used property : logₐ(xⁿ) = nlogₐx]
⇒ 8log6 + 6×2log6³ + 12log6 - 24log6

what's a factor in math
Answer:
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
A=5,5-(+2)+(-11,5)-(-6)
The value of the expression A will be negative 2.
What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The expression is given below.
A = 5.5 - 2 + (-11.5) - (-6)
Simplify the expression, then the value of the expression A will be

The solution of the given linear equation in one variable 5(s -12) - 24 = 3(s + 2) is at s = 45.
According to the given question.
We have an equation.
5(s -12) - 24 = 3(s + 2)
Since, we have to solve the above linear equation in one variable.
As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the linear equation in one variable 5(s -12) - 24 = 3(s + 2) is given by
5(s - 12) -24 = 3(s + 2)
⇒ 5s - 60 - 24 = 3s + 6 ( by distributive rule)
⇒ 5s - 84 = 3s + 6
⇒ 5s - 3s = 84 + 6
⇒ 2s = 90

For an analysis of variance comparing four treatments, msbetween = 12. The value of ssbetween is 36.
What is variance ?A measure of variability is the variance. It is determined by averaging the squared deviations from the mean. Your data set's variability is shown by its variance. The variance is greater in respect to the mean when the data are more dispersed.
Finding the mean will allow you to compute the population's variance (the average). Squaring the result after deducting the mean from each data point in the sample. The outcomes are squared to make the adverse findings positive.
Data points' deviations from the mean are quantified by their variance. Layman defines variance as the degree to which a set of data (numbers) deviates from the mean (average) value.

The medical examiner is called in to determine how long a person has been deceased. The rate of decay is -0.026 and the temperature outside is 55 degrees. When the medical examiner arrives the temperature of the body was 82 degrees. Assuming the person had a normal body temperature of 98.6 degrees when they passed, how long had the person been deceased? Round answer to the nearest hour.
The person had been deceased for 12 hours
According to given data,
Temperature of normal person had 98.6 degrees,
and the temperature of the person was 82 degrees
outside temperature is 55 and
rate of decay is -0.026
The temperature of body drops :
98.6 - 82 = 16.6 degrees
[tex]\frac{16.6}{55}[/tex] ≈ 0.3
[tex]\frac{0.3}{0.026}[/tex] ≈ 12 hours
therefore, 12 hours had the person been deceased

A farmer needs to make a 1000 -square-foot rectangular enclosure for her cows. She wants to save money by purchasing the least amount of fencing possible to enclose the area. What whole-number dimensions will require the least amount of fencing?
F. 8ft by 125ft
G. 10ft by 100 ft
H. 20ft by 50 ft
J. 25ft by 40 ft
The dimensions of the 1000-square-foot rectangular enclosure with the least amount of fencing should be 25ft by 40ft.
The amount of fencing needed can be calculated by getting the perimeter of each choice of dimensions.
Perimeter is defined as the distance that surround any two-dimensional shape. For a rectangle, the perimeter is given by the formula
P = 2l + 2w
Solving for the perimeter of each of the following choices:
F. 8ft by 125ft
P = 2l + 2w
P = 2(8) + 2(125)
P = 16 + 250
P = 266ft
G. 10ft by 100ft
P = 2l + 2w
P = 2(10) + 2(100)
P = 20 + 200
P = 220ft
H. 20ft by 50ft
P = 2l + 2w
P = 2(20) + 2(50)
P = 40 + 100
P = 140ft
J. 25ft by 40ft
P = 2l + 2w
P = 2(25) + 2(40)
P = 50 + 80
P = 130ft
The dimensions with the least perimeter will require the least amount of fencing.
Hence, a 1000 -square-foot rectangular enclosure, with dimensions 25ft by 40ft, will require the least amount of fencing.

When striping the practice football field, Mr. Hawkins first painted the sidelines. Next he marked off 10-yard increments on one sideline. He then constructed lines perpendicular to the sidelines at each 10-yard mark. Why does this guarantee that the 10 -yard lines will be parallel?
This ensures that the lines will be parallel since two lines that are perpendicular to one another must also be parallel.
What is a perpendicular line?Two lines that meet or cross at right angles (90°) are known as perpendicular lines in geometry. The word "perpendicular" comes from the Latin "perpendicularis," which denotes a plumb line.

Find the 32 nd term of each sequence. 23,30,37,44, ...........
The 32nd term of the arithmetic sequence AP is calculated to be 240.
What basically is an AP arithmetic sequence?In mathematics, an arithmetic progression (AP) is a list and possibly sequence of numbers where each term is collected by adding a sequence towards the term before it.
The fixed number, without regard to arithmetic progression, is signified by the letter 'd.'Common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of AP: an = a + (n - 1) dThe sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l = last term of the AP.Finally, here is the answer to the question:
The following are the numbers with in displayed sequence:
23,30,37,44, ...........
The 32nd number in the series must be investigated because it contains 32 terms.
The common difference between two consecutive terms of an AP that are equal is denoted by the letter 'd.'
Let's consider the first term is'a₁' = 23.
Let's consider 'a₂' = 30 is the second term.
Let's consider the third term is 'a₃' = 37.
Substitute the values the above obtained equation; the 32nd term is-
d = a₂ - a₁
Estimate the common difference;
d = 30 - 23
d = 7
Substitute the values in the next formula; the 32nd term is
The formula given will estimate the nth term equation;
nth term of an AP: an = a + (n - 1) d
Total number of terms ; n = 32
Initial term is a = 23
Common difference d = 7
Substitute the given values in nth term formula;
a₃₂ = a + (n - 1) d
a₃₂ = 23 + (32 - 1)(7)
a₃₂ = 23 + 217
a₃₂ = 240
Thus, the 32nd term value of the given arithmetic sequence is estimated to be 240.
