Answer:
No solution
Step-by-step explanation:
Let's solve using substitution (substitute 15x+2 for y):
-15x+15x+2=1
2=1
No solution
Another method...
Since these lines have the same slope, but different y-intercepts, they are parallel. This means they will not intersect therefore there is...
No solution
Answer:
sqrt (65) = 8.062 units = x
Step-by-step explanation:
use Pythagorean theorem for a right triangle
a ^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
4^2 + x^2 = 9^2
x^2 = 9^2 - 4^2
x^2 = 65
x = sqrt 65
I don’t know- the first thing I would think is that x=15*y because 30=15*2
So that’s my thinking, which means that if x=5, then y=5/15 or 1/3 or as a decimal .33
However I’m not sure if that’s right- I hope it helps!
Answer:
112cm^3
Step-by-step explanation:
Formula for volume of a cone is:
r = radius and h = height
To find the radius you divide the diameter by 2:
12.9 ÷ 2 = 6.45
Now substitute values into the formula:
Which equals 112cm^3
