What is an equation in maths?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.
Given that we have all the equations set up, we need to solve for W.
1.) w+3w=90
4w=90
w=22.5
2.) w+3w+w+3w=90
8w=90
w=11.25
3.) 2*w+2*3w=90
2w+6w=90
8w=90
w=11.25
4.) 2*(3w+w)=90
6w+2w=90
8w=90
w=11.25
Now, out of all those which one was different?
A. (w+3w=90)
This equation did not match with all the others is (w+3w = 90)

Solve for x. Give explanation
Answer:
x = 47 degrees.
Step-by-step explanation:
The angles in a triangle add up to 180 degrees, therefore:
x + 43 + 90 = 180
x = 180 - 43 - 90
x = 180 - 133
= 47 degrees.
how do i find the surface area and volume of this shape?
Answer:
3,761.46 m³
Step-by-step explanation:
Volume of a cone = 1/3πr²h
π = 3.14
radius, r = diameter/2
= 25/2 = 12.5 m
Height, h = 23m
Volume of a cone = 1/3πr²h
= 1/3 * 3.14 * 12.5² * 23
= 1/3 * 3.14 * 156.25 * 23
= 11,284.375 / 3
= 3761.4583333333
Approximately,
Volume of the cone = 3,761.46 m³

2. Eli has 600 cubes that are 1 cubic inch. Select the smallest length a cube- shaped box can have while being able to hold the 600 cubes. A 7 in. B 8 in. C 9 in. D 10 in.
Answer:
9 in
Step-by-step explanation:
We need to find x in x^3 > 600
For x=8, 8^3 = 512 < 600 (Too Small)
For x=9, 9^3 = 729 > 600 (Just right)
For x=10, 10^3 = 1000 > 600 (Too big)
Therefore, the smallest length of the cube-shaped box is 9 in.
Find mDE. Round your answer to the nearest hundredth.
Answer:
[tex]50.04[/tex]
Step-by-step explanation:
Use this formula for arc length
[tex]2\pi \times r( \frac{x}{360} )[/tex]
where r is the radius and x is the arc measure.
We know Arc de is 8.73 so we are finding x.
R equal 10.
[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi \times x = 3142.8[/tex]
[tex]x = \frac{3142.8}{20\pi} [/tex]
x=50.04
The value of the angle will be 50.04.
What will be the angle?It is given in the question that
The arc of the circle A=8.73 In
The radius of the circle =10 In
Now from the formula of arc
[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]
[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]
[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]
[tex]\theta=50.04[/tex]
Thus the value of the angle will be 50.04

Which of the following systems of equations creates the graph of (-3.4, 2.3)?
Option 1 : y= 2x+4
y= -1/3x-8
Option 2 : y= 1/2x-8
y= -3x-8/3
Option 3 : y= 1/2x+4
y= -3x-8
Option 4 : y= 2x-8
y= -1/3x-8/3
I need an answer ASAP, I will mark u brainliest if the answer is valid! thx
Answer:
C
Explanation:
The answer is C because when you plug in (-3.4) as x in that equation, you get 2.3 as an answer which means that option is correct.
[tex]y = \frac{1}{2} x + 4[/tex]
[tex] = \frac{1}{2} ( - 3.4) + 4[/tex]
[tex] = 2.3[/tex]
When you plug in x for other options, you do not get the correct value for y so this is the only answer.
