Answer: 0.7g/cm³
Step-by-step explanation:
Let the average density of Saturn be represented by x.
The average density of earth is 5.5g/cm³ which is 0.1g/cm³ less than 8 times Saturn. This can be formed into an equation as:
8x - 0.1 = 5.5
8x = 5.5 + 0.1
8x = 5.6
x = 5.6/8
x = 0.7
Therefore, the average density of Saturn is 0.7g/cm³
Answer:
1.)21°
2.)51°
3.)73°
4.)50°
Step-by-step explanation:
1.) 90° - 69°
= 21°
2.) 90° - 39°
= 51°
3.) 90° - 17°
= 73°
4.) 90° - 40°
= 50°
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
so 96 km on 8 liters means if you divide both numbers by 8,
the car goes 12k on 1 liter of gas
now multiply both numbers by 15
180 km on 15 liters
180 km is your answer
