Select all numbers that are irrational. 1049−−√ 3.14 π 0.5
The answer would be 10/49 and π which are irrational numbers from the definition of the irrational number.
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
It is given that:
The numbers are:
10/49, 3.14, π, 0.5
As we know, from the definition of the irrational, the numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
The numbers 10/49 and π are irrational numbers.
Thus, the answer would be 10/49 and π which are irrational numbers from the definition of the irrational number.

write the equation of the line MN, which is formed by the points M(-3,5) and N(2,0)
Step 1
Find the slope of the given line
Let
[tex]M(-3,5)\ N(2,0)[/tex]
we know that
the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute the values
[tex]m=\frac{0-5}{2+3}[/tex]
[tex]m=\frac{-5}{5}[/tex]
[tex]m=-1[/tex]
Step 2
Find the equation of the line
we know that
the equation of the line into point-slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=-1[/tex]
point N [tex](2,0)[/tex]
substitute the values
[tex]y-0=-1(x-2)[/tex]
[tex]y=-x+2[/tex]
therefore
the answer is
[tex]y=-x+2[/tex]
Find the integer a such that
a.a ≡ 43 (mod 23) and −22 ≤ a ≤ 0.
The integer a such that a ≡ 43 (mod 23) and −22 ≤ a ≤ 0 is -3. A zero, a positive natural number, or a negative integer with a minus sign is an integer.
What do we mean when we say that integers are congruent to modulo?When two positive integers a and b are divided by a positive integer n, they are said to be congruent modulo n (or an is congruent to b modulo n), or if a b is divisible by n. It can be expressed as a b mod n, where n is the modulus.If n is a positive integer, then the integers a and b are said to be congruent modulo n, as denoted by the expression a b (modn).Division algorithm Allow dd and aa to be both positive integers. Following that, there are two distinct integers, qq and rr, where rd0 and rd are equal, resulting in a = dq + ra = dq + rTherefore,
-3 is in between -22 and 0 so a =-3
a ≡ 43 (mod 23) and −22 ≤ a ≤ 0.
a ≡ 43 (mod 23)
≡ 43-22 (mod 23)
Simplifying,
≡ 20 (mod 23)
≡ 20-23 (mod 23)
Then we get,
≡ -3 (mod 23)
-3 is in between -22 and 0 so a =-3

What is the value of x?
Mark earns $135 for selling a $1500 refrigerator. Which sale listed has the same commission rate? $36 commission on a $400 dryer or B) $40 commission on a $500 dryer sale C) $210 commission on $1400 oven sale d) $30 commission on a $600 freezer sale?
salelisted has the same commssion rate. ?
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given that Mark earns $135 for selling a $1500 refrigerator.
Since proportions states that two fractions are equal , so we will use proportions to find the same commission rate with the listed price from our given choices.
We can set proportion for commission and listed price as:
[tex]\frac{\text{Commission}}{\text{Listed price}}=\frac{135}{1500}[/tex]
Let us compare our given choices one by one.
A. $36 commission on a $400 dryer.
[tex]\frac{36}{400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{9}{100}=\frac{9}{100}[/tex]
[tex]0.09=0.09[/tex]
We can see that commission rates for both items are equal, therefore, option A is the correct choice.
B. $40 commission on a $500 dryer sale.
[tex]\frac{40}{500}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{2}{25}=\frac{9}{100}[/tex]
[tex]0.08\neq 0.09[/tex]
We can see that both commission rates are different, therefore, option B is not a correct choice.
C. $210 commission on $1400 oven sale.
[tex]\frac{210}{1400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{3}{20}=\frac{9}{100}[/tex]
[tex]0.15\neq 0.09[/tex]
Since the commission rates are different, therefore, option C is not a correct choice.
D. $30 commission on a $600 freezer sale.
[tex]\frac{30}{1400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{3}{140}=\frac{9}{100}[/tex]
[tex]0.0214\neq 0.09[/tex]
Since the commission rates are different, therefore, option D is not a correct choice.
how many fossil kits with 10 samples each have the same number of fossils as 30 fossil kits with 8 samples each?
Answer:
24 fossil kits.
Step-by-step explanation:
Given,
The number of fossil kits = 30,
the number of samples each has = 8,
So, the total samples = number of fossil kits × the number of samples contained by each kit
= 30 × 8
= 240,
Let x be the number fossil kits with 10 samples each,
Total samples = 10x
According to the question,
10x = 240
[tex]\implies x =\frac{240}{10}=24[/tex]
Hence, there would be 24 fossil kits with 10 samples each.

A person made an estimate for a three–minute interval. the estimate was 241.5 seconds. what was the error of this estimate?
A scatterplot is produced to compare the size of a lake to the number of fish that are in it. There are 15 data points, each representing a different lake. The points are widely dispersed on the scatterplot with no pattern of grouping. Interpret what the results of the scatterplot tell you about the relationship between the two variables.
Based on the dispersion of the scatterplot, we can infer that there is no relationship between the variables.
Relationships in scatterplots Data points are used to predict relationships. If a line can be drawn based on these data points, then a relationship exists.The fact that these data points are dispersed however and offer no form of grouping, means that the variables are not related and show no correlational trend.

What are 2 ways three people can share fifths?
Final answer:
Three people can share fifths by dividing one pie into five slices and each taking three, or dividing three pies into fifteen slices and each person getting one slice from each pie. Both methods ensure each person receives three-fifths of a pie.
Explanation:
Two ways that three people can share fifths involve division and allocation of pie (or any other divisible whole). One way is to take a single pie, divide it into five equal slices, and each person takes three slices. However, since we need to divide these among three people and a pie has only five slices, we'll end up with a fraction of a slice per person. The second way is to start with three pies, divide them so that there are a total of fifteen slices (five slices per pie), and then each person gets one slice from each pie, totaling three slices per person.
Here are two arithmetic representations of the scenarios:
First method: (3 slices/person) / 5 slices = 3/5 per personSecond method: 1 slice from each of 3 pies / 5 slices per pie = 3/5 per personWhether we are dealing with one pie or three, each person ends up with the same fraction of the total available pie: three-fifths.
At an automobile factory, 1849 parts are made in 4 hours. What is the average rate at which parts are made per hour?
Answer:
462.25
Step-by-step explanation:
At an automobile factory, the number of parts are made in 4 hours = 1849.
We have to calculate the average rate of production per hour.
We will divide the production of parts in 4 hours by 4 to get the number of parts made per hour.
The average rate of production in one hour = [tex]\frac{1849}{4}[/tex]
= 462.25/hour
462.25 parts are made per hour.

Line IJ has an equation of a line y = −3x − 8. Which of the following could be an equation for a line that is parallel to line IJ?
A) y=3x+7
B) y=1/3x+7
C) y= -3x+7
D) y= -1/3x+7
C) y = -3x +7
Step-by-step explanation:It's all about recognizing patterns.
The form of the equation is ...
... y = mx + b
In this form, the coefficient of x, which we called "m" in the above, is the slope of the line. When two lines have the same slope, they are parallel. So, we're looking for an equation that has an x-coefficient of -3, the same as in the given equation.
The coefficient of x in selection C is -3, so that is our answer choice.
... C) y = -3x +7
Answer:
y = -3x +7 which is option C
