P is inversely proportional to V
That is P = k/V where k is some constant.
Plug in the given values for P and V:-
25 = k/400 giving k = 10,000
so the relation is P = 10,000 / V
when V = 200 , 200P = 10,000
Its A
That would be 27+3y becuase if you see the 3 and 9 back to back that’s multiplication so 9x3 is 27 so you can put it as 27+3y and that’s how you do it so basically your answer is 27 hope that helped you!
Area of a circle = pi * r^2
A = (3.14) * 8^2
A = 3.14 * 64
A =200.96 units ^2
Answer:
x= 1/2
y=3
Step-by-step explanation:
it is easier to subtract both equation and obtain a new one
1) 6x+0.4y=4.2
2) -4x+0.4y=-0.8
---------------------------------
1) -2)= 10x+0=5 leading to x=1/2
Now just eval x=1/2 in any of the original equations, for instances
1) 6*(1/2) +0.4*y=4.2, which leads to y=3
Answer:
0.7, 70/100 or 7/10
Step-by-step explanation:
70 squares are shaded.
So 70/100 of all squares are shaded
