6g + 4(-5+4g) = 1 - g
6g - 20 + 16g = 1 - g
22g - 20 = 1 - g
22g + g = 1 + 20
23g = 21
g = 21/23 or 0.913043 in decimal form.

Answer:

Step-by-step explanation:
Given
Initial Level = 340 m
Number of stages = 4
Difference in each stage = 60 m
Required
Determine the depth of the submarine after 4 stages
First, we have to calculate the total distance moved towards the surface of the sea;
This is calculated as



This implies that the submarine moved a total distance of 240 metres;
It;'s new depth is calculated as follows;



<em>Hence, its new depth after 4 stages of rising is 100m</em>
Answer:828.96m^2
Step-by-step explanation:
radius(r)=8m
L=25m
π=3.14
total surface area of cone(tsa)=πxr^2+πxrxL
Tsa=3.14x8^2+3.14x8x25
Tsa=3.14x8x8+3.14x8x25
Tsa=200.96 + 628
Tsa=828.96
1 cup = 0.5 pints
3 x 0.5 = 1.5 pints = 1 1/2 pints
