Let english = x
farsis be y
acc. question
x=78y
or x-78y=0--------------------1 eq
also
x+y=130 ------------------ 2 eq.
from 1 and 2
x-78y=0
x+y=130
on substracting
-79y= -130
y = 130/79
1.7 approx
=> x= 78*1.7
x= 132.6
hence english speaking= 132.6
farsis speaking = 1.7
Answer:
16.8
Step-by-step explanation:
Find your answer by using the formula of a cone (v= πh)
r= 2 (half of your diameter, which is 4)
h= 4
By inserting your radius and height, you get v= π()4.
Put that into a calculator and you get 16.75516, which rounds to 16.8.
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
