This graph shows how the total number of postcards Kendra buys is related to the number of days she spends on vacation.
What is the constant of variation? Write your answer as a fraction.
Answers
In the given context the constant of variation(k) is 2/5.
What is the constant variation?The link between variables remains constant because of the constant of variation.
It is useful to use one of the following formulas to determine the constant of variation for an equation/
If k is the variational constant, then either x = k/y (inverse variation) or
x = ky (direct variation) should be used.
From the given graph we can observe the relationship between the number of postcards Kendra buys is related to the number of days is in direct variation when x = 5, y = 2.
∴ x = ky.
5 = 2k.
k = 2/5.
The constant of variation is 2/5.

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?
Answers
Answer: i think it is 46.38 %
Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)
Answer:
38.3%
Step-by-step explanation:
We have two equations to find the answer.
1. Discount = OG Price * Discount by 100%
2. Final Price = OG Price - Discount
So fill in the first equation :
Discount = 28.99 * 38.3/100
Discount = 28.99 * 0.38
Saved = $11.10
Now for the second equation :
Final Price = 28.99 - 11.10317
Final Price = $17.89
Therefore the discount is 38.3%

Answer:
slope = -1/4, y-intercept = 50
Step-by-step explanation:
x=0 y=50
x=100 y= 25

Answer:

Step-by-step explanation:
Perimeter of ∆ ABC = Perimeter of ∆ PQR
3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59

How do you find the missing height of a triangle?
Answers
Answer:
Use the Pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex] where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:
[tex]3^{2} +4^{2} =c^{2}[/tex]
Simplify the equation to get:
[tex]9+16=c^2[/tex]
Add 16 and 9 to get 25 and take the square root of both sides:
[tex]\sqrt{25} =c[/tex]
The sqrt of 25 is 5. Therefore, the length of the hypotenuse, or c, is 5.
Answer:
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle.

170 guests yesterday called for room service 255 guests did not call for room service what percentage call for room service
Answers
Answer: 40%
Step-by-step explanation:
Number of guests that yesterday called for room service = 170
Number of guests that did not call for room service = 255
Total number of guests = 170 + 255 = 425.
The percentage that call for room service = Those that call for room service / Total guest × 100
= 170/425 × 100
= 0.4 × 100
= 40%

The required equation of inequality is y > - 3/2 x + 2.
We have given a graph of inequality for finding their equation.
What is inequality?
Inequality is a statement of an order relationship for greater than, greater than or equal to, less than, or less than or equal to, between two numbers or algebraic expressions.
From graph we can see that the line is passing through the points (0,-2) and (-4,4).
Since we know that the slope of a graph,
[tex]m = (y_2 - y_1)/(x_2 - x_1 )[/tex]
=[tex](4 - (-2))/(-4 - 0)[/tex]
⇒[tex]m = (-3)/( 2)[/tex]
Also we know the equation of line passing through the point (x_(1,) y_1) having slope be,
[tex]y - y_1 = m (x - x_1)[/tex]
Therefore, the equation of line passing through (0, -2) and having slope -3/2 be,
⇒ y - (-2) = - 3/2 x
⇒ y = - 3/2 x + 2
Since the graph is shaded left side to the line so, this equation can be written as
y > - 3/2 x + 2
Thus, this is the required equation of inequality.
