Calculate the first and second velocities of the car with three washers attached to the pulley, using the formulas v1 = 0. 25 m
Travka [436]

The first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.

Given data:

The value of the first distance is, d1 = 0.25 m.

The value of the second distance is, d2 = 0.50 m.

<h3>What is velocity?</h3>

The ratio of distance covered by an object in a specific direction and the time taken to cover the distance is known as the velocity of the object. Mathematically, the expression for the velocity is,

v = d/t

Here, d is the distance covered.

And t is the average time taken to cover the distance.

Then the first velocity of the car at 0.25 m is,

v1 = d1/t1

v1 = 0.25 / t1

Here, t1 is the average time for the first distance.

And the second velocity of the car with four washers at the 0. 50 m mark is,

v2 = d2/t2

v2 = 0.50 /t2

here, t2 is the average time for the second distance.

Thus, we can conclude that the first and second velocities of the car are 0.25/t1 and 0.50/t2 respectively.

the total amount of flour in a bakery after receiving new stock equal to 3/10 of its current stock (x)
Ivenika [448]

If you're look for an equation to find how much flour there would be :

y would be the flour in the bakery after a certain number of stocks based on x, the number of times the flour has been stocked. The equation would require the initial amount of flour, though, which you have not provided.

the constant 1.3 will be used to show that the stock is increasing by 30% each time while including the initial amount of flour.

y= (initial amount of flour)(1.3)^x
