For a party in kindergarten balloons of three colors were bought: red, green, and yellow. There were 40 red balloons, the number

marta [7]

Answer: Total number of balloons are 100

and part of balloon is blown up is $\frac{1}{20}$ .

Step-by-step explanation:

Since we have given that

Number of red balloons = 40

Number of green balloons is given by

$\frac{3}{5}\times 40\\\\=3\times 8\\\\=24$

Number of yellow balloons is given by

$24\times \frac{3}{2}\\\\=12\times 3\\\\=36$

So, Total number of balloons were brought to the kindergarten is given by

$40+24+36=100$

Number of red balloons are popped is given by

$\frac{1}{20}\times 40\\\\=2$

Number of green balloons are popped is given by

$\frac{1}{12}\times 24\\\\=2$

Number of yellow balloons are popped is given by

$\frac{1}{36}\times 36\\\\=1$

total number of balloons are blown up is given by

$2+2+1=5$

Therefore, Part of balloon is blown up is given by

$\frac{5}{100}=\frac{1}{20}$

Hence, Total number of balloons are 100

and part of balloon is blown up is $\frac{1}{20}$ .

What's the explicit formula for the sequence :")

zzz [600]

Hello from MrBillDoesMath!

Answer:

a(n) = 12 - 3(n-1) , n = 1,2,3.,,

Discussion:

The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence

a(n) = 12 - 3(n-1) , n = 1,2,3.,,

Thank you,

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:

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