How many 4-digit numbers can be chosen that are even and greater than 3000?
Answer: 4-digit numbers can be chosen that are even and greater than 3000 is equal to 192.
Step-by-step explanation:
Given data,
4-digit numbers can be chosen that are even and greater than 3000.
For even numbers, each formed 4-digit number must end with 2, 4, or 6. And each such number greater than 3000 must begin with 3, 4, 5, 6, or 7.
Since five digits [1–5] are available, the number may have four or five digits.
All five-digit numbers are greater than 3000, and there are 5! = 120 permutations of the five digits.
Four-digit numbers greater than 3000 must have one of three digits (3 or 4 or 5) as its first digit. The next three digits must be selected from the four remaining digits available, so the number of permutations is: 4 * 3 * 2 = 24.
There are 3 * 24 = 72 numbers of the form 3xxx, 4xxx, 5xxx (all of which are greater than 3000).
The number of possible sequences of [1–5] greater than 3000 include 120 four-digit numbers and 72 five-digit numbers, so the total is 192.
Therefore,
4-digit numbers can be chosen that are even and greater than 3000 is equal to 192.

an apartment building has 15 apartments. there 5 more 2-bedroom apartments than 1- bedroom apartments. how many 2- bedroom apartments are there?
The number of 2 bedroom apartments that are there is 10.
How to illustrate the information?Let the number of one bedroom = b
Since there are 5 more 2-bedroom apartments than 1- bedroom apartments. This will be b+5.
There are 15 apartments. Therefore, the expression will be:.
b + b + 5 = 15
2b + 5 = 15.
2b = 15 - 5.
2b = 10
b = 10 / 2
b = 5
Number of 2 bedroom = b + 5 = 5+5 = 10.
Therefore, the number of 2 bedroom apartments that are there is 10.

Use the information to find a linear algebraic equation model that can be used to answer the question.
Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 3 more than 4 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 103?
By solving some linear equations, we can see that Mark has 20 marbles and Don has 83 marbles, and these are the numbers they need to sell.
How many does each boy have to sell if the total number of marbles is 103?Let's define the variables:
x = number of marbles that Mark has.y = number of marbles that Don has.We know that the linear equation:
y = 4x + 3
"If Don has 3 more than 4 times the number of marbles Mark has"
The total number of marbles is 103, then:
x + y = 103.
Then we have two linear equations:
Replacing the first equation into the second one:
x + (4x + 3) = 103.
5x + 3= 103
5x = 100
x = 100/5 = 20
So Mark has 20 marbles and Don has 83 marbles, and these are the numbers they need to sell.

Which equations are in standard form? Select all that apply.
The equations which represent the standard form are:
A) 3x+12y=-6
D) -10x+7y=13
F) 3/4x+y=8
G) 5x+14y=3
Given we have a set of equations.
A technique for expressing linear equations is the standard form. The standard form, the slope-intercept form, and the point-slope form are some of the numerous ways that a linear equation can be expressed. Ax + By = C is a representation of the general form, commonly referred to as the standard form, of linear equations.
A) 3x+12y=-6
the above equation is in the form of Ax + By = C
B) x-y = 1
the above equation is not in the form of Ax + By = C
C) 2x=9
the above equation is not in the form of Ax + By = C
D) -10x+7y=13
the above equation is in the form of Ax + By = C
E) 6y=11
the above equation is not in the form of Ax + By = C
F) 3/4x+y=8
the above equation is in the form of Ax + By = C

find the point (x y) on the unit circle that corresponds to the real number t. t = π/6
Answer:
The value of x is -√3/2 and the value of y = -1/2.
Step-by-step explanation:
It is given that t = π/6 and we need to find the point (x y) on the unit circle that corresponds to the real number t.
Now,
Let us suppose that the real number 't' is to be of an arc length from the positive X-axis.
=> t = π/6
Further, if we look at the graph given below;
We observe that the reference angle π/6 is one of the standard angles with the ratio of opposite to adjacent sides as indicated above.
=> x, y = -√3/2, -1/2
Therefore, it can be inferred from the graph that the value of x is -√3/2 and the value of y = -1/2.

How many times larger is the 8 in 184.36 than 9,027.83
Answer: Thus, the number with the larger value of 8 is 184.36 and it is 100 times larger.
Step-by-step explanation:
First we can find out the place value,
Then we can write,
Define Place value :
Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value. The number 42,316 is different from 61,432 because the digits are in different positions.
[or]
Place value of a digit can be defined as the position of the particular digit in a given number.
For Example :
The place value of 7 in 1870 is 70
Given the data,
First we use digit is : 184.36
Second we use digit is : 9027.83
Place value of 8 in First digit is ⇒ 184.36 is 80
Place value of 8 in Second digit is ⇒ 9027.83 is 0. 8
We can solve the Ratio is :
Ratio = 80/ 0.8
Ratio = 100 times
Therefore,
Thus, the number with the larger value of 8 is 184.36 and it is 100 times larger.

Applying the triangle sum theorem, the value of x is: 4.
How to Apply the Triangle Sum Theorem?When we add the three interior angles of a triangle together, the sum must be equal to 180 degrees according to the triangle sum theorem.
Given the triangle with the following interior angles, 35°, (22x - 3)°, and 60°. Therefore:
35 + (22x - 3) + 60 = 180 [triangle sum theorem]
Solve for x
35 + 22x - 3 + 60 = 180
Combine like terms
92 + 22x = 180
Subtract 92 from each side of the equation
92 + 22x - 92 = 180 - 92
22x = 88
Divide both sides by 22
22x/22 = 88/22
x = 4
Thus, applying the triangle sum theorem, the value of x is: 4.

The acres of land Leo plant with soyabeans is 108 acres.
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now given that,
Total farms of land = 576 acres
Part of land planted soyabeans = 3/16 of total farms of land
Putting the values we get,
Part of land planted soyabeans = 3/16 of 576 acres
Simplifying we get,
Part of land planted soyabeans = 3/16 * 576 acres
Solving we get,
Part of land planted soyabeans = 1,728/16 acres
Thus, we get
Part of land planted soyabeans = 108 acres
