Answer: 112%
Step-by-step explanation:
Let x = the cost of the shoes
If the cost of the sweater is 12% more than the cost of the shoes, then 1.12x is the cost of the sweater.
To convert the 1.12x into a percentage, multiply 1.12 by 100
This gives you: 112%
Answer:
Infinite many solutions - all are correct
Step-by-step explanation:
Since f(x) and g(x) are the same function, their graphs will be the same and all points on the line are solutions. All x values will be solutions. This means there are infinitely many.
You can see it algebraically too:
-2x-6 = -2x-6
-2x+2x-6 = -2x +2x -6
0-6 = 0-6
-6=-6 True. Infinite solutions.
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
Answer:
The surface area of the cylinder will be "131.88".
Step-by-step explanation:
The given values are:
Height of cylinder,
h = 4 m
Radius of cylinder,
r = 3 m
As we know,
The surface are of cylinder is:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
Ugh this hurts my head just looking at it, but I'll show the process.
PEMDAS
Addition before subtraction (Not that it matters here).
2 - (-4) is the same as adding 4. This equals 6.
-1 - (-3) is the same as adding 3. This equals 2.
Adding these two expressions together equals 8.
Showing my work...
2 - (-4) + (-1) - (-3)
6 + (-1) - (-3)
6 + 2
8
