Answer:
3
Step-by-step explanation:
Answer:
-3 and -4
Step-by-step explanation:
x = 1st number
y = 2nd number
set up system of equations:
2x + 3y = -18
3x + 2y = -17
elimination method: multiply 1st equation by -2 and second by 3
-4x - 6y = 36
+
<u> 9x + 6y = -51</u>
5x = -15
x = -3
find y: 2(-3) + 3y = -18
-6 + 3y = -18
3y = -12
y = -4
turning point of namely U-turn or vertex point, Check the picture below.
Answer:2
Step-by-step explanation:
Given
Physics problem requires 20 min
Math problem require 10 min
suppose x question of Physics and y questions of Math are done
so according to the question

Time require for x Physics problem 
Time require for y Math problem 
so,

On solving (1) and (2)
we get
and 
Maximum no of Physics question which can be solved is 2
Answer:
V=97.08
Step-by-step explanation:
The formula for the volume of a cone is V= 1/3 pi (r)^2 (h)
To find the radius divide the diameter by 2. 6/2=3
Plugin: V=1/3 pi(3)^2(10.3)=97.08
