1. A clerk is paid P 45.25 per hour for 40 hours a week, 1.50 times the
Ierofanga [76]

Answer:

The clerk's total earnings is P520.375

Step-by-step explanation:

Given

Earnings = $45.25 per hour

Overtime = 1.5 * regular earnings

Holiday = double regular earnings

Required

Determine his earnings for 5 hours (overtime) and 2 hours (holiday)

From the question, we understand that

Regular Earnings = P45.25

Overtime Earnings = 1.5 * P45.25

Overtime Earnings = P67.875

Overtime Earnings for 5 hours = 5 * P67.875

Overtime Earnings for 5 hours = P339.375

Holiday Earnings = 2 * Regular Earnings

Holiday Earnings = 2 * P45.25

Holiday Earnings = P90.5

Holiday Earnings for 2 hours = 2 * P90.5

Holiday Earnings for 2 hours = P181.0

The clerk's total earnings is calculated as thus:

Total = Overtime Earnings for 5 hours + Holiday Earnings for 2 hours

Total = P339.375 + P181.0

Total = P520.375

Gnoma [55]

Answer:

49.8 ft²

Step-by-step explanation:

the picture in the attached figure

given:

a=3,  b=1   c=1.8

To know the surface area:

surface area of the figure=surface area of cube+surface area of triangular prism

first lets find out the area of cube and triangular prism.

surface area of cube=4*a²

surface area of cube= 4*3² => 36  ft²

surface area of triangular prism=2*[a*c]+2*[a*b/2]  = 2*[3*1.8]+[3*1]

surface area of triangular prism=10.8 +3  = >  13.8 ft²

Therefore,  surface area of the figure=36 ft²+13.8  ft²

surface area of the figure= 49.8 ft²

the answer is:

49.8 ft²
