The following given problem can be expressed in the form
of:
E = 5.60 * T1 + 8.40 * T2
where,
E = total earning
T1 = normal hours worked
T2 = overtime hours
Assuming that the maximum T1 hours is 40 hours. Beyond
that is considered overtime, therefore:
287 = 5.60 * 40 + 8.40 * T2
T2 = 7.5 hours
<span>Therefore 7.50 overtime hours is needed.</span>
Answer:
Its either A or C
Step-by-step explanation:
Answer:
<ABC=50
<EDB=30
<DFC=60
Step-by-step explanation:
<ABC=50 BECAUSE ANGLE SUM PROPERTY
90+40+50=180
<EDB=30 BECUSE ANGLE SUM PROPERTY
100+50+30=180
<DFC=60 BECAUSE ANGLE SUM PROPERTY
30+90+50=180

By applying <em>reflection</em> theory and constructing a <em>geometric</em> system of two <em>proportional right</em> triangles, the height of the stainless steel globe is approximately 140 ft.
<h3>How to estimate the height of the stainless steel globe</h3>
By physics we know that both the angle of incidence and the angle of reflection are same. Thus, we have a <em>geometric</em> system formed by two <em>proportional right</em> triangles:
5.6 ft / 4 ft = h / 100 ft
h = (5.6 ft × 100 ft) / 4ft
h = 140 ft
By applying <em>reflection</em> theory and constructing a <em>geometric</em> system of two <em>proportional right</em> triangles, the height of the stainless steel globe is approximately 140 ft.
