sam knows that 1 inch is about 2.54 centimeters. about how many centimers is 3 inches
how can i solve it formula y= mx + b
Answer:
y = 4/3x - 4
Step-by-step explanation:
you are given b
so y = mx -4
you can look at the graph and see the slope from there. like the y-intercept and the x-intercept
(0,-4) and (3,0)
slope formula is y2-y1/x2-x1
and so you do -4-0/0-3
-4/-3.
so your slope formula would be
y = 4/3x - 4

Answer:
x = y = 24.
Step-by-step explanation:
Here we are given a right angled triangle in which one of the angles is 45° . And one of the known side is 24√2 . And we need to find out the value of x and y.
Here we can use the ratio of sine as ,[tex]\qquad\rm\longrightarrow sin45^o =\dfrac{p}{b} [/tex]
Substituting the respective values,
[tex]\qquad\rm\longrightarrow sin45^o =\dfrac{x}{24\sqrt2}[/tex]
Value of sin 45° is 1/√2 . So that,
[tex]\qquad\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{x}{24\sqrt2}[/tex]
Cross multiply ,
[tex]\qquad\rm\longrightarrow x =\dfrac{24\sqrt2}{\sqrt2} [/tex]
Simplify,
[tex]\qquad\rm\longrightarrow \underline{\boxed{\rm \blue{x = 24}}} [/tex]
Again , the third angle will be 45° . we know that the sides opposite to equal angles are equal. Therefore here ,
[tex]\qquad\rm\longrightarrow \underline{\boxed{\blue{\rm y = 24}}}[/tex]
The values of x and y are 24
The triangle is a right angled triangle with an angle measure of 45 degrees.
The above means that:
The values of x and y are equal
So, we have:
[tex]x^2 + y^2 = (24\sqrt 2)^2[/tex]
Evaluate the squares
[tex]x^2 + y^2 = 1152[/tex]
x and y have equal values,
So, we have:
[tex]x^2 + x^2 = 1152\\\\[/tex]
[tex]2x^2 = 1152[/tex]
Divide through by 2
[tex]x^2 = 576[/tex]
Take the square roots of both sides
[tex]x = 24[/tex]
Hence, the values of x and y are 24

Answer:
1) 100/2 = 50°.
2) 50°
3) 50°
Reasons: rhombus, perpendicular bisector
- Toodles!~
[tex]\bold{\huge{\pink{\underline{ Solutions}}}}[/tex]
Answer 18 :-We have,
Rhombus RAMS and Angle SMA = 100°
In rhombus, The diagonals bisect each other at an angle of 90° .Therefore,
[tex]\sf{\angle{ AMR = 1/2}}{\sf{\angle{ SMS}}}[/tex]
[tex]\sf{\angle{ AMR = 1/2 × 100 }}[/tex]
[tex]\sf{\angle{ AMR = 50° }}[/tex]
Thus, Angle AMR is 50°
Hence, Option D is correct
Answer 19 :-We know that,
The sides of rhombus are equal and parallel to each other[tex]\sf{\angle{ AMR = }}{\sf{\angle{ RMS}}}[/tex]
[ Alternative interior angles ]
[tex]\sf{\angle{ RMS = 50° }}[/tex]
Thus, The value of Angle RMS is 50°
Hence, Option B is correct
Answer 20 :-Here, we have to find the value of mAngleMSA
In ΔCMS,
By using Angle sum property
[tex]\sf{ 50° +}{\sf{\angle{MSC + 90° = 180° }}}[/tex]
[tex]\sf{\angle {MSC = 180° - 140°}}[/tex]
[tex]\sf{\angle{MSC = 40° }}[/tex]
Therefore,
[tex]\sf{m}{\sf{\angle{MSA = 40° }}}[/tex]
Thus, The value of mAngle MSA is 40°
find the unknown size of angles
Step-by-step explanation:
y+110=180 (cointerior angle)
y=180-110
y=70
y=z(Alternate angle)
z=70
x=z(corresponding angles)
x=70

The Shoe Outlet bought boots for $60 and marks up the boots 55% on the selling price. What is the selling price of the boots?
Answer: The markup- 122.225%
Revenue/price- 133.33$
Gross profit- 73.33%
Step-by-step explanation:
The gross profit P is the difference between the cost to make a product C and the selling price or revenue R.
P = R - C
To calculate revenue R based on the cost C and the desired gross margin G, where G is in decimal form:
R = C / ( 1 - G)
The gross profit dollars P is the revenue dollars R from the sale times the gross margin G percentage, where G is in decimal form :
P = R * G
The markup percentage M, in decimal form, is gross profit P divided by cost C.
M = P/ C
M * 100 will change the decimal to a percentage.
The selling price of the boots is $93.
Given information:
The Shoe Outlet purchased the boots for $60 and increased their price by 55%
To calculate the selling price of the boots with a 55% mark-up, to add 55% of the original cost to the original cost.
Calculate the mark-up amount as follows:
Mark-up = 55% of $60
Mark-up = 0.55 * $60
Mark-up = $33
Add the mark-up to the original cost to find the selling price as follows:
Selling Price = Original Cost + Mark-up
Selling Price = $60 + $33
Selling Price = $93
So, the selling price of the boots is $93.

i really need some help on this math problem?can you help me
Answer:
7 units
Step-by-step explanation:
Forming an equation:
There is a one-time signup fee. Let that be represented by "a".
Then, there's also a weekly fee. Let that be represented by "b", i.e., the fee for one week is "b" units.
==> If she goes to the gym for x weeks, then her total weekly fee will be "b" times "x" units.
If we represent her total cost after membership by "y", our equation becomes:
[tex] \boxed{ \sf{y = a + bx}}[/tex]
We're provided with three values of x and y.
When x = 6, y = 133When x = 12, y = 175When x = 24, y = 259The solution to the equation:
Substitute the respective values of x and y into the equation.
#1
133 = a + 6b
==> a = 133 - 6b
#2
175 = a + 12b
Since we only need the values of two variables we'll use only two equations.
Substituting from #1 for a:
175 = (133 - 6b) + 12b
==> 175 = 133 + 6b
==> 175 - 133 = 6b
==> 42 = 6b
==> b = 7
And b is the amount she pays each week.
So, the answer is 7 units.

How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimeter is 185 centimeters? l=25cm h=12cm
Answer:
Width= 30
Length= 62.5
Step-by-step explanation:
First we simplify the length to width ratio
25/12=
2 1/12 ratio of length to width
width=x
length=2 1/12x
Make the equation for this ratio's perimeter being equal to 185
2(2 1/12x) + 2(x)=185
Solve for x
4 1/6x +2x=185
6 1/6x=185
x=30
Substitute the answer in for x to find the length and width
Width= 30
Length= 2 1/12(30)
Length= 62.5
