Herbert has sold 90, 45, 103 and 68 appliances in the last four months, respectively. How many appliances will he need to sell t

Elena-2011 [213]

Answer:

The sale this month = 79

Step-by-step explanation:

Let the amount he needs to sell this month = x

$Average = \frac{sum\ of\ individual\ data\ }{number\ of\ entries}$

$Average= \frac{90\ +\ 45\ +\ 103\ +\ 68\ +\ x}{5}$

Note that number of entries = number of months = 5

To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:

$77 = \frac{306\ +\ x}{5} \\cross-multiplying\\77\ \times\ 5\ = 306\ +\ x\\385 = 306\ +\ x\\x =385\ -\ 306\\x = 79$

Alenkasestr [34]

Answer:

$\huge \boxed{\mathrm{99.98 \ cm}}$

Step-by-step explanation:

A quadrant is quarter of a circle.

The perimeter of a quarter of a circle is $\frac{2\pi r}{4} +2r$ .

The radius $r$ is 28 cm.

$\frac{2\pi (28)}{4} +2(28)= 99.982297...$

The perimeter of the quadrant with radius 28 cm is approximately 99.98 cm.
