Answer:
which function describes this table of values x y 0 0
Answer:
15
Step-by-step explanation:
Int angle : Ext angle : Total
13 : 2 : 15 (13+2)
We know that, int angle + ext angle = 180
Let's introduce a variable x to help solve this ratio
Our ratio is now - 13 x : 2 x : 15x
Use your total ratio and equate it to your total angle size
15 x = 180
x = 180 / 15 = 12
So,
Int angle = 13 x = 13 (12) = 156
Ext angle = 2 x = 2 × 12 = 24
Now, use this formula.
Ext angle = 360 / n
(n represents your number of sides)
24 = 360 / n
n = 360 / 24 = 15

20 cm³ of pure alcohol is added to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution.
Let x represent the volume of pure alcohol (100%) in cm³ needed to be added. Hence:
x * 100% + 10 cm³ * 10% = 70% * (x + 10 cm³)
x * 1 + 10 * 0.1 = 0.7 * (x + 10)
x + 1 = 0.7x + 7
x - 0.7x = 7 - 1
0.3x = 6
x = 20 cm³
Therefore 20 cm³ of pure alcohol is added to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution.

Answer:
x=8
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 10^2
36 + x^2 = 100
Subtract 36 from each side
36-36 +x^2 = 100-36
x^2 = 64
Take the square root of each side
sqrt(x^2) = sqrt(64)
x = 8
Answer:
x = 8
