Write 13 divided by 4/7 as a multiplication expression
almond37 [142]

Answer:

13/1*7/4

Step-by-step explanation:

The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.

An just finished taking statistics, and wants to do a survey on the average salary of Spring 2019 HCC graduates. She calculates
Zanzabum

Answer:

The appropriate answer is "256".

Step-by-step explanation:

Given:

Standard error,

SE = 128.13

Standard deviation,

\sigma = $2050

As we know,

⇒ SE = \frac{\sigma}{\sqrt{n} }

or,

⇒ \sqrt{n}= \frac{\sigma}{SE}

By substituting the values, we get

         =\frac{2050}{128.13}

         =\frac{205000}{12813}

     n = (\frac{205000}{12813} )^2

         =255.98

or,

         =256

The diameter of the wheel of a cart is 856 m, it will cover 2690.28 m in 56 complete revolutions.
Anvisha [2.4K]
It looks like the question you are asking is how far will the cart travel after 56 complete revolutions.

To answer this you will use the distance it will travel in 1 revolution (2690.28 m) and multiply it by 56.

2690.28 x 56 = 15655.68 meters or about 15.66 km.
