What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 39 million
Let the value of B = 10⁷
On simplifying the value of A , we get
A = 39 million
A = 39000000
So , the value A can be written in powers of 10 as
The value of A = 39 x 10⁶
On simplifying the equation , we get
The value of A = 3.9 x 10⁷
Now , the value of A > B
And , 3.9 x 10⁷ > 10⁷
Therefore , the value of A is greater than B
Hence , The value 3.9 x 10⁷ is greater than the value 10⁷

Simplify the equation: 2x - 3 > 2(x+9)
Answer:
no solution
Step-by-step explanation:
2x - 3 > 2(x+9)
Distribute
2x-3 > 2x+18
Add 3 to each side
2x-3+3 > 2x+18+3
2x> 2x+21
Subtract 2x from each side
2x-2x> 2x-2x+21
0 > 21
This is never true so there is no solution
Answer:
See below.
Step-by-step explanation:
So we have the inequality:
[tex]2x-3>2(x+9)[/tex]
First, distribute the right side:
[tex]2x-3>2x+18[/tex]
Subtract both sides by 2x. Both the left and right cancels:
[tex](2x-3)-2x>(2x+18)-2x\\-3>18[/tex]
-3 is not greater than 18. Therefore, the inequality is never true.
The 7-digit numbers in a given area code have the form ABC-XXXX, where X, B, and C can be any digit 1-9 and A is
restricted to 0-9. There are two other restrictions:
• B and C cannot both equal 1 since these values are designated for other purposes such as 911 (emergency)
and 411 (information), and
• 555-0100 through 555-0199 are reserved for fictional uses such as in television shows or movies.
According to these conditions, how many 7-digit numbers are possible in a single area
code?
Answer:
The number of 7-digit numbers are possible in a single area code is 5248600
Step-by-step explanation:
The given parameters are;
The number of digits in the area code = 7
The possible digits for X, B and C are 1 - 9 = 9 digits
The number of possible digits for A is 0 - 9 = 10 digits
Exceptions
1) B and C cannot both =
2) 555-0100 through 555-0199 are reserved for television or movies
Therefore, we have, the number of 7 digits numbers without exceptions = 10×9⁶ = 5314410 numbers
The number of the exceptions are
Exception 1) 10 × 1 × 1 × 9 × 9 × 9 × 9 = 65610 numbers
Exception 2) 555-0100 through 555-0199 = 0199 - 0100 = 200 numbers
The number of possible numbers = 5314410 - 65610 - 200 = 5248600
The number of 7-digit numbers are possible in a single area code = 5248600.

I need help asap pls
Answer:
y = x - 1
Step-by-step explanation:
Lines that are parallel have the same slope. The slope of the given equation is 1. This means that the new equation will also have a slope of 1.
Use the point-slope form to find the equation with the given point and slope.
y - y₁ = m(x - x₁)
y - 2 = 1(x - 3)
y - 2 = x - 3
(y - 2) + 2 = (x - 3) + 2

The formula for the surface area of a cylinder is 2pi r(r+h) where rrr is the radius of the cylinder's base and h is its height. A certain pole has a cylinder-like shape, where the base's radius is 10centimeters and the height is 2 meters. What calculation will give us the estimated surface area of the pole in square centimeters?
Answer:
4200πcm²Step-by-step explanation:
Given the formula for the surface area of a cylinder as S = 2πr(r+h) where r is the radius of the cylinder's base and h is its height.
Given parameters
base radius of the cylindrical pole = 10 cm
Height of the cylindrical pole = 2 m
Since 100 cm = 1 m, then 2 m = 200 cm
Height of the cylindrical pole (in cm) = 200 cm
Required
Surface area of the pole (in cm²)
Using the formula for finding the surface area of a cylinder as shown above;
[tex]S = 2\pi r(r+h)\\\\S = 2\pi (10)(10+200)\\\\S = 2\pi 10(210)\\\\S = 2\pi * 2100\\\\S = 4200\pi cm^2[/tex]
Hence the surface area of the pole in square centimetres is 4200πcm²
Find the area of the shaded regions of the following figures. Will Give Brainliest!! Answer ASAP
Answer:
Rectangle 1 area: 53 units squared
Shape 2 area: 43.75 units squared
Step-by-step explanation:
Shape 1:
We need to find the area of the two triangles in this rectangle and subtract it from the total area of the rectangle.
Total area of the rectangle:
13 * 5 = 65
Area of triangles (they are congruent):
1/2 * 4 * 3 = 6
6 * 2 = 12
65 - 12 = 53
The area of the shaded part is 53 (I don't know what your unit of measurement is. Just say units.)
Shape 2:
First, let's find the area of the parallelogram at the top.
10 * 3 = 30
Now, let's find the area of the rest of the shape. Triangle first...
1/2 * 4 * 1.5 = 3
Now, the rectangle and the tiny triangle we can section out at the end:
7 * 1.5 = 10.5 + 1/4 (Triangle) or 0.25 = 10.75
Total area: 10.75 + 3 + 30 = 43.75

When reflecting across both axis, we switch up the signs but keep the order of the coordinates.
Thus, (-2, 8) and (2, -8) are reflections and (4, -3) and (-3, 4) are also reflections.

Can u guys PLEASE answer this question ASAP. Two wooden boxes, both with dimensions 80 cm, 1 m and 25 cm, are placed on the ground, one on top of the other as shown. The entire outside surface is then painted. Find the area of the painted surface.
Answer:
34000cm or 340m
Step-by-step explanation:
We have to find total surface area.
dimensions of 1 wooden box =
l = 1m = 100cm
b = 80cm
h = 25cm
∴ In the case of 2 =
l = 100cm
b= 80cm
h = 25 + 25 = 50cm
T.S.A = 2(lb + lh + bh)
= 2(100*80 + 100*50+ 80*50)
= 2(8000+5000+4000)
= 2*17000
= 34000cm
= 340m
A man spends 1/3 of his salary on accomodation and 2/5 of the remainder on food. What fraction is left for other purposes?
Greetings from Brasil...
Let's find the equivalent fractions
A/B ; C/D ⇔ A·D/B·D ; C·B/B·D
Bringing to our problem:
A/B ; C/D ⇔ A·D/B·D ; C·B/B·D
1/3 ; 2/5 ⇔ 1·5/3·5 ; 2·3/3·5 ⇔ 5/15 ; 6/15
Now we can sum/add the equivalent fractions
5/15 + 6/15 = 11/15
11/15 to accomodation and food
15/15 = total
total - (accomodation and food) = other purposes
15/15 - 11/15 = 4/15
So 4/15 its the fraction for other purposes

If you have to make AB perpendicular to CD, rotate AB clockwise, until and unless both the lines intersect at 90 degrees.
What are angles? What is a mathematical function, equation and expression?Angles : the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function
Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Equation : A mathematical equation is used to equate two expressions.
Given is that as you move point B, the angle formed between AB and CD varies.
If you have to make AB perpendicular to CD, rotate AB clockwise, such that the point B moves in clockwise direction, until and unless both the lines intersect at 90 degrees.
Therefore, if you have to make AB perpendicular to CD, rotate AB clockwise, until and unless both the lines intersect at 90 degrees.

In Orthographic drawing, we represent several 2D views of an object to obtain a 2D object.
The most common views of Orthographic drawings are top, right, and front.
Though the figure mentioned in the question represents the top, right, and front part view and as per the definition of perspective drawing it is not flat, it cant be looked flat when opened which satisfies the definition of net so, the figure satisfies option 3.

Just do it in a simple way.
Use the properties of parallel lines, and find the value of x to find angke 1.
angle 1= angle 2 { alternate angles on parallel lines are equal }
[tex]2x + 20°= 3x + 10°[/tex]
