Fred can create 20 animal balloons every 15 minutes. solve ratio table
DerKrebs [107]

The number of animal balloons created in 15 minutes = 20

The number of animal balloons created in 1 minute = \frac{20}{15}

So, the number of animal balloons created in 6 minutes = \frac{20}{15}\times 6 = 8

And, the number of animal balloons created in 45 minutes = \frac{20}{15}\times 45 = 60

So, the solved ratio table will be:

15.20

6.8

45.60

Which of the following is NOT a unit energy? (select all that applies)
docker41 [41]

Answer:

Calories and joules are both units of energy.

Kelvin, Celsius, and Temperature are measures of temperature not technically units of energy.

Since temperature measures the energy of atoms, a true temperature scale must be a positive scale since atoms cannot have a negative energy. Of the three kelvin is technically the only true measure of energy.

What is the emperor call formula for a compound that is 31.9% potassium 28.9% chloride and 39.2% oxygen
My name is Ann [436]
Lets take 100 g compound.
It will have
K - 31.9 g
Cl - 28.9 g
O - 39.2 g

M(K) = 39.1 g/mol
M(Cl) = 35.5 g/mol
M(O) = 16.0 g/mol

K - 31.9 g*1/mol/39.1 g ≈ 0.816 mol
Cl - 28.9 g*1 mol/35.5 g ≈ 0.814 mol
O - 39.2 g*1mol/16.0 g ≈ 2.45 mol

K : Cl : O = 0.816 : 0.814 : 2.45

K : Cl : O = 1 : 1 : 3
