40% helping customers + 13% doing paper work = 53% of his time.

This means 100% - 53% = 47% of his time he is doing other tasks.

Find the sum of the first 47 terms of the following series, to the nearest integer.

topjm [15]

Answer:

The sum of the first 47 terms of the given series = 6016

Step-by-step explanation:

Given the sequence

13, 18, 23, ...

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

$18-13=5,\:\quad \:23-18=5$

As the difference between all the adjacent terms is the same.

so

$d=5$

$a_1=13$

Arithmetic sequence sum formula

$n\left(a_1+\frac{d\left(n-1\right)}{2}\right)$

Put the values

$d=5$

$a_1=13$

$n=47$

$=47\left(13+\frac{5\left(47-1\right)}{2}\right)$

$=47\left(13+\frac{5\left(47-1\right)}{2}\right)$

$=47\left(13+115\right)$

$=47\cdot \:128$

$=6016$

Thus, the sum of the first 47 terms of the given series = 6016

Answer:

$360\ cm^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the bottom rectangle</u>

$A = l * w$

$A = 10\ cm * 12\ cm$

$A = 120\ cm^2$

<u>Step 2: Determine the area of the back rectangle</u>

$A = l * w$

$A = 10\ cm * 5\ cm$

$A = 50\ cm^2$

<u>Step 3: Determine the area of the top rectangle</u>

$A = l * w$

$A = 10\ cm * 13\ cm$

$A = 130\ cm^2$

<u>Step 4: Determine the area of the triangle</u>

$A = \frac{h*b}{2}$

$A = \frac{5\ cm * 12\ cm}{2}$

$A = \frac{60\ cm^2}{2}$

$A = 30\ cm^2$

<u>Step 5: Determine the surface area</u>

$120\ cm^2 + 50\ cm^2 + 130\ cm^2 + 2(30\ cm^2)$

$360\ cm^2$

Answer: $360\ cm^2$
