Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
Answer:
h = 1.34 inches
Step-by-step explanation:
Given that,
The volume of cone, V = 3.6 cubic inches
Let the radius of cone is, r = 1.6 inches
We need to find the height of the cone. The formula for the volume of a cone is given by :
h = 1.34 inches
So, the height of the cone is equal to 1.34 inches.
30. 30 is the answer to this question.
