21+21+31.5+31.5 over here we split both of the numbers in half, creating a different way of writing the equations!
or the easier way would be:
63+42 All we did here was switch the numbers to create the same equation in the opposite form!

Ike Phillips worked 6.7 hours at time-and-a-half pay and 3.4

ikadub [295]

Working out the different pay rates earned by Ike Phillips :

Time and half pay rate = $17.055
Double pay rate = $22.74
Time and half earning = $114.2685
Double rate earning = $77.316
Gross earning = $646.3845

Let :

Regular rate = $11.37

Total earning for the week = $454.80

Double pay hours = 3.4

Time and half pay hours = 6.7

Time and half pay rate = 1.5 × regular pay rate = 1.5 × 11.37 = $17.055

Double pay rate = 2 × regular pay rate = 2 × 11.37 = $22.74

Time and half earning = rate × time = $17.055 × 6.7 = $114.2685

Double rate earning = rate × time = $22.74 × 3.4 = $77.316

Gross earning = (regular + time and half + double earning) = $(454.80+114.2685+77.316) = $646.3845

Therefore, Ike's gross earning for the week is $646.3845

Maslowich

In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

$d= \sqrt{12h}$

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:

$d= \sqrt{12*350}=64.81$

Therefore, the approximate distance to the horizon for the person will be 64.81 km
