Solve the equation or formula for the indicated variable. S=3r^4t, for t

algol [13]

we are given

$S=3r^{4t}$

Since, we have to solve for t

so, we will isolate t on anyone side

divide both sides by 3

$\frac{S}{3} =r^{4t}$

now, we can take ln both sides

$ln(\frac{S}{3}) =ln(r^{4t})$

we can simplify it

$ln(\frac{S}{3}) =4tln(r)$

divide both sides by 4ln(r)

$t=\frac{ln(\frac{S}{3})}{4ln(r)}$ ..............Answer

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the

hram777 [196]

Answer:

1.21 kilograms

Step-by-step explanation:

Let y represent the mass of the empty basket, and x represent the mass of each ball

Create a system of equations:

3x + y = 3.64

5x + y = 5.26

Solve by elimination by multiplying the top equation by -1

-3x - y = -3.64

5x + y = 5.26

Add them together, then solve for x:

2x = 1.62

x = 0.81

Plug this back into one of the equations and solve for y:

3x + y = 3.64

3(0.81) + y = 3.64

2.43 + y = 3.64

y = 1.21

So, the mass of the empty basket is 1.21 kilograms
