The particle will reach 50 km/hr when x = 32.25 hours

Step-by-step explanation:

A physicist working in a large laboratory has found that light particles

traveling in a particle accelerator  increase velocity in a manner that

can be described by the linear function - 4 x + 3 y = 21, where

  • x is the time in hours
  • y is the velocity in kilometer per hour

We need to find when a certain particle will reach  50 km/h

∵ - 4 x + 3 y = 21 is a linear function

∵ x represents the time (number of hours)

∵ y represents the velocity in km/h

∵ The velocity of a particle will reach 50 km/h

- Substitute y by 50 in the function above

∴ - 4 x + 3(50) = 21

∴ - 4 x + 150 = 21

- Subtract 150 from both sides

∴ - 4 x = -129

- Divide both sides by -4

∴ x = 32.25 hours

The particle will reach 50 km/hr when x = 32.25 hours

A glass is 1 3 full. Then 40cm3 of orange juice is poured in. The glass is now 5 7 full. What is the total volume of the glass?
Effectus [21]

Answer:

V= 105cm^3

Step-by-step explanation:

V=volume

(1/3)V+40=(5/7)V

(5/7)V-(1/3)V=40

(15/21)V-(7/21)V=40

(8/21)V=40

(21/8)(8/21)V=(21/8)(40

V=21*5

V=105 cm3

(1/3)(105)=35, 35+40=75, 75/105=15/21=5/7
