43/100 kilograms of flour.

Answer:

Total amount of the flour used is \frac{43}{100} kg.

Step-by-step explanation:

Baker starts with \frac{4}{10} kilograms of flour to make bread.

He further adds flour to his bread mixture = \frac{3}{100} kg

Now we have to calculate the amount of flour he used to make the bread.

Total flour = \frac{4}{10}+\frac{3}{100}

                 = \frac{40+3}{100}

                 = \frac{43}{100} kg

Therefore, total amount of the flour used is \frac{43}{100} kg

A top-loading washing machine has a cylindrical basket that rotates about a vertical axis. The basket of one such machine starts
damaskus [11]

Answer:

n_{tot}=44rev

Step-by-step explanation:

In order to solve this problem we can make use of the following formula:

\theta=(\frac{\omega_{f}+\omega_{0}}{2})t

where θ is the total angle the basket has turned, ω is the angular velocity and t is the time.

Generally theta is written in radians and omega is written in radians per second. Now, since the revolutions are directly related to the radians and they want us to write our answer in revolutions, we can directly use the provided speeds in the formula, so we can rewrite it as:

n=(\frac{f_{f}+f_{0}}{2})t

where n represents the number of revolutions and f is the frequency at which the basket is turning.

The movement of the cylindrial basket can be split in two stages, when it accelerates and when it decelerates. So let's analye the first stage:

n=(\frac{4rev/s+0}{2})(9s)=18rev

and now let's analyze the second stage, where it decelerates, so we get:

n=(\frac{0rev/s+4rev/s}{2})(13s)=26rev

So now that we know how many revolutions the cylindrical basket will take as it accelerates and as it decelerates we can add them to get:

n=18rev+26rev=44rev

So the basket will turn a total of 44 revolutions during this 22s interval.

Given f(x) 2^x -7 find the x intercepts
brilliants [131]
Be sure to include the "=" sign:   <span>f(x) = 2^x -7 

To find the x-intercepts, set f(x) = 0 and solve for x:  2^x - 7 = 0,
or
2^x = 7

Take the common log of both sides:  x log 2 = log 7
                              log 7
Solve for x:     x = --------- = 2.81 (approx)
                               log 2

Answer:

The density of cube is 6.17959 \frac{g}{cm^{3} }

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

\rho = \frac{m}{V}

Where,

\rho is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V=0.53^{3}=0.148877cm^{3}

Now, the Density of the cube will be

\rho = \frac{m}{V}

\rho = \frac{0.92}{0.148877}

\rho =6.17959

Thus, The density of cube is 6.17959 \frac{g}{cm^{3} }
