Answer:
216 & 288
Scale Width; 13.5
Scale Length; 18
Actual Lengths will be multiplied by 16 because scale is 1:16
Actual Width; 216 (13.5 x 16)
Actual Length; 288 (18 x 16)
Step-by-step explanation:
X+0=18
2x+y=19
(-2)x+(-2)0=(-2)18
2x+y=19
0+y= -17
2x+ (-17)=19
2x=36
y=-17
x=18
Step-by-step explanation:
It is given that,
The diameter of a tennis ball is 2 cm and the diameter of the softball is 1 cm. So, radius of tennis ball is 1 cm and radius of softball is 0.5 cm.
Both balls are in the shape of sphere. Half of the balls will becomes hemisphere. The surface area of hemisphere is given by :

Taking ratio of both balls, i.e.


So, the surface area of a half of the tennis ball is 4 times of he surface area of a half of the softball.
If L= m+ f, then to find f, u move m to the other side. So u subtract it. Cause you have to do the opposite. So f= L-m
L is in the green box
