SCORPION-xisa [38]

Answer:

0.02 mm

Step-by-step explanation:

Let's convert the numbers given in decimal first, for ease of calculation.

Thickness of soles of feet = 1  2/5th mm, which is 1.4 mm

THick ness of eyelids are 1/70 TIMES the thickness of soles

So we multiply 1/70 [in decimal that is 0.0143 (rounded to 4 decimals) ] with 1.4:

0.0143 * 1.4 = 0.02 mm

So, the thickness of skin on your eyelids is 0.02 mm

Patti's Pet Palace has a 90-gallon fish tank. When it needs to be cleaned, it can be drained at a rate of 2 gallons per minute.

You would have 90 cause the tank is full then you would subtract that from 2x because 2 gallons drain per minute so your answer is 90-2x

Answer:

The volume of the sphere is 972π mm³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 9mm

π = pi

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * π * (9mm)³

V = π * ⁴⁄₃ *729mm³

V = π * 972mm³

V = 972π mm³

The volume of the sphere is 972π mm³

Julie cashed a paycheck and repaired her brother $10 that she borrowed from him. She then spent $30 on fuel for her car and half
pochemuha
Remark
She starts out with x
She spends 10 dollars paying back her brother (that's - 10)
She spends 30 dollars on fuel (that - 30)
She spends 1/2 what's left on a tent ( that's 1/2 (x - 10 - 30) )
She then spent 29.45  on running shoes. 1/2 (x - 10 - 30) + 29.45 is her expenditures.

After all that she has 17.75 left. 

Equation
x - 10 - 30 - 1/2(x - 10 - 30) - 29.45 = 17.75   

Solve
Begin by adding 29.95 to both sides. 
x - 10 - 30 - 1/2(x - 10 - 30)  = 17.75 + 29.45 
x -10 - 30 - 1/2(x - 10 - 30)  = 47.20  Add the like terms on the left.
x - 40 - 1/2(x - 40) = 47.20 Add 40 to both sides. Don't go inside the brackets.
x - 1/2x + 1/2 (40) = 87.20
1/2 x + 20 = 87.20                        Subtract 20 from both sides.
1/2 x = 67.20                                Multiply by 2
x = 134.40
