How many natural numbers are there between 1 and v? Pls explain how you got that!
Answer:
you need to the prime number to get the sum for the distance between 1 and v.
Step-by-step explanation:
Natural numbers are what you use when you are counting one to one objects. You may be counting pennies or buttons or cookies.
If you want to find the numbers between the two you will need an expression to consolidate your question as an example 3r, 6y, 2by in order to find the Natural number between these three questions you need to use equations such as 3r*2by+6y therefore would be 6br + 2y.
A Prime number is a natural number of a particular kind . Any natural number is equal to 1 times itself.

Harry bought a used dirt bike for $1,050. Before purchasing the bike, Harry had a total of
$2,250 in his savings account. What percentage of his savings account did Harry spend on
the dirt bike?
Answer:
. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Step-by-step explanation:
Final answer:
Harry spent 46.67% of his savings on the dirt bike, calculated by dividing the price of the dirt bike by the amount in his savings account and then multiplying by 100.
Explanation:
The question is asking how to calculate the percentage of Harry's savings that was spent on a dirt bike. To find the percentage, you would divide the amount spent on the dirt bike by the total amount in the savings account and then multiply by 100. Harry spent $1,050 on the dirt bike and had $2,250 in his savings account originally.
Here's the step-by-step calculation:
Divide the cost of the dirt bike by the total savings: $1,050 / $2,250.You get a decimal result from step one, which you then multiply by 100 to get a percentage.The calculation is ( $1,050 / $2,250 ) × 100 = 46.67%.Therefore, Harry spent approximately 46.67% of his savings on the dirt bike.1) find x -------> 3x-8

Step-by-step explanation:
Twenty eight slips of paper are numbered 1 through 28 and are distributed among a group of people. A random number generator is used to select a single number between 1 and 28, inclusively
A fair decision is made using this process
How many people could be in this group?
A. 3
B. 6
C. 7
D. 12
Answer:
Option C is the correct answer.
Step-by-step explanation:
Since a random number generator is used to select a single number between 1 and 28, inclusively;
For a fair decision to be made during the process, the number of persons in the set must be a divisor of 28.
Let's list the divisors of 28:
The divisors of 28 are {1, 2, 4, 7, 14, 28}
The only option that contains one of the divisors is option C which is 7.

The ratio of side lengths for two similar cubes is į.
Determine the ratios for each of the following. Show your work or explain how you got your answers.
a. the perimeter of one face of the smaller cube compared to the perimeter of one face of the larger
cube
b. the total surface area of the smaller cube compared to the total surface area of the larger cube
c. the volume of the smaller cube compared to the volume of the larger cube
The ratio of the perimeter of one face for the two cubes is 1/2, the ratio for the total surface area is 1/4, and the ratio for the volume is 1/8.
Explanation:The student wants to find the ratios of the perimeter of one face, the total surface area, and the volume of two similar cubes having side length ratio of 1/2.
Perimeter of one face: Since each face of a cube is a square, the perimeter is 4 times the side length. As the ratio of side lengths is 1/2, the ratio of the perimeters would also be 1/2. This is because perimeter is a one-dimensional measure, therefore the ratio stays proportional to the side length.Total Surface Area: The total surface area of a cube is 6 times the area of one face (a square). Since the area is a two-dimensional measure, it's proportional to the square of the side length ratio, hence the ratio of the surface areas of two similar cubes would be (1/2)² = 1/4.Volume: The volume of a cube is the cube of the side length. Since the volume is a three-dimensional measure, it is proportional to the cube of the side length ratio, so the ratio of the volumes of two similar cubes would be (1/2)³ = 1/8.Learn more about Ratio of Similar Cubes here:

What is in an ellipse?An ellipse is a curve formed by a plane, that intersects a cone at an angle with respect to the base. It is a curve surrounded by two focal points. Ellipse is a locus of points, the sum of whose distances from two foci is constant.
What is an ellipse shape?An ellipse is a circle that has been stretched in one direction, to give it the shape of an ova
What is an ellipse example?An ellipse has an eccentricity less than one, and it represents the locus of points, the sum of whose distances from the two foci of the ellipse is a constant value. A simple example of the ellipse in our daily life is the shape of an egg in a two-dimensional form and the running tracking in a sports stadium.
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity
An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution.
what is the general formula of ellipse ?The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1, represents an ellipse centered at the origin and with axes lying along the coordinate axes. In general, an ellipse may be centered at any point, or have axes not parallel to the coordinate axes.

Step-by-step explanation:
ILL GIVE BRAINLIEST IM ON A TIME CRUNCH PLEASE HELP!!!!! What is the solution to the system of equations below? y = negative three-fourths x + 3 and y = –12
(20, –12)
(12, –12)
(–6, –12)
(–12, 12)
Answer:
The system of equations as described:
y = (-3/4)x + 3
y = -12
Combining two equations, we have:
=> -12 = (-3/4)x + 3
=> -15 = (-3/4)x
=> x = -15 x (-4/3) = 20
=> Solution is (20, -12)
=> Option A is correct.
Hope this helps!
:)
Step By Step:
The equations given to us are:
y = (-3/4)x + 3
y = -12
Now that we have y we can change that to -12
-12 = (-3/4)x + 3
-15 = (-3/4)x
x = -15 x (-4/3) = 20
This would give us (20, -12)

A. (20,-12)Hope this helps

Solve the system of equations.
3x + 4y = -23
x = 3y + 1
y =
X=
Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1

The librarian was checking the thicknesses of several books and found that the average thickness of a book was 1.8 centimeters. She found this by averaging the thicknesses of five different books. Four of the thicknesses were 1.4 cm, 1.9 cm, 2.1 cm, and 2.4 cm. What was the thickness of the fifth book that she measured?
Answer:
1.2 cm
Step-by-step explanation:
1.8 * 5 = 9
9 - (1.4 + 1.9 + 2.1 + 2.4) = 1.2
1.2 + 1.4 + 1.9 + 2.1 + 2.4 = 9
