Nathan earns $1500 a week. Calculate his new weekly wage if he receives a pay rise of 20%
bazaltina [42]

Answer:

$1800

Step-by-step explanation:

1. Approanch

An easy way to calculate one's salary after they recive a raise is to, convert the percent that one's salary is increased into a decimal; divide the percent by 100. Then multiply the increase as a decimal by the original salary, to attain the amount the salary is raised by. Finally add the amount the salary is raised by to the original salary to find the new salary. A quicker way to do this is to convert the percent by the salary is increased into a decimal. Then add 1 to that number. Finally one will multiply that number by the original slary and get the new salary.

2. Solving

Original salary; 1500

Raise; 20%

<u>a. convert the raise as a percent into a decimal, then add 1</u>

20% = 0.2

0.2 + 1 = 1.2

<u>b. multiply the number by the original salary</u>

1.2 * 1500

1800

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;I=\textit{initial amount}\to &19300\\&#10;r=rate\to 20\%\to \frac{20}{100}\to &0.20\\&#10;t=\textit{elapsed time}\to &2\\&#10;\end{cases}&#10;\\\\\\&#10;A=19300(1+0.2)^2

Please I’m struggling
insens350 [35]

Answer:

1080cm²

Step-by-step explanation:

surface area=sum of the area of all the shapes

area of triangle=1/2*base*height

1/2*24*10=120*2(because there are two triangles)=240cm²

10*14=140cm²

24*14=336cm²

Area of slanting figure=26*14=364cm²

add all the results

240+140+336+364=1080cm²
