Change 0.45° to equivalent minutes and seconds. Round to the nearest second if necessary.

konstantin123 [22]

0.45° in minutes is 27.36 minutes and in seconds is 21.6 seconds.

Why is it necessary to divide decimal degrees by 60 to obtain minutes and seconds?

In a complete rotation, circles and spheres have 360 degrees. One degree is divided into sixty minutes, and one minute is divided into sixty seconds.

You may see that your measurement is 91 full degrees plus 0.456 of a degree if you have 91.456 degrees.

How 0.45° is converted to equal minutes and seconds?

To convert 0.456 degrees to minutes, multiply 0.456*60 and you will get the answer as 27.36 minutes. You now have a total of 27 minutes and 0.36 of a minute.
To express 0.36 minutes seconds in decimal form, multiply 0.36*60 to get 21.6 seconds. You can round up to twenty two seconds because your decimal 0.6 is bigger than 0.5.

Find the area of this trapezoid. Be sure to include the correct unit in your answer.14 ft16 ft7 ft17 ft

goblinko [34]

The area of a trapezoid can be found through the formula

$A=\frac{a+b}{2}\cdot h$

where a and b are the bases and h the height, then,

$\begin{gathered} A=\frac{14+7}{2}ft\cdot7ft \\ A=10.5ft\cdot7ft \\ A=73.5ft^2 \end{gathered}$

Mekhanik [1.2K]

Answer:

30.0

Step-by-step explanation:

Given our data is normally distribute with $\mu=21.3$ and $\sigma=5.9$

-Top 7% is given by find the z-value corresponding to p=(1-0.07)=0.93

-We substitute our values in the equation below;

$z=\frac{\bar X-\mu}{\sigma}\\\\\\=\frac{X-21.3}{5.9}, z_{0.035}=1.476\\\\\therefore 1.476=\frac{X-21.3}{5.9}\\\\X=5.9\times 1.476+21.3\\\\=30.0084\approx30.0$

Hence, the minimum score required for the scholarship is 30.0
