Answer:
B) y = 129º
Step-by-step explanation:
since a triangle is 180º in total, the you have to subtract 71 and 58 from 180 which will give you 51º which gives you the amount for x
and the line that the triangle is on is also 180º in total, so you subtract the 51 from 180 to give you a total of 129º which is the amount for y
Answer:
(x - 4)(x - 4)
x = 4
Step-by-step explanation:
x² - 8x + 16
= (x - 4)(x - 4)
x - 4 = 0
x = 4
The answer is A and D because if you square both of them, they are less than 16. hope this helps!
Answer:
The cone'll require about 37.5 cm of tubing
Step-by-step explanation:
To do this, we need to know that the volume of the medium will have to be the same volume of the cone that will be printed.
Then, the volume of the cone is:
V = π*r^2*h/3
V = 3.14 * 5^2*8 / 3 = 209.33 cm^3
We can assume that the tubing is a cylinder so:
V = π*r^2*h
The radius is 1 1/3, and this is:
1*3 + 1 = 4/3
Solving for h we have:
h= V/π*r^2
h = 209.33 / 3.14*(4/3)^2
h = 209.33 / 5.58
h = 37.5 cm
Answer:
6/35
Step-by-step explanation:
20/35 - 14/35= 6/35
