<em>A(a) = 24 cm²</em>
<em>A(b) = 40.04 cm² ≈ 40 cm²</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>area formula (rectangle)</em>
<em>A = l × w</em>
<em>A(a) = 8cm × 3cm = 24 cm</em>
<em>A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²</em>
<em>Good luck !</em>
525, I believe. Because each ticket is $5, and in total, the tickets were $105. So I multiplied 5 x 105=525.
Please correct me if I'm wrong.
Answer:
Answer to the question:
Step-by-step explanation:
α= 54º
V= 66 ft/s
g= 9.8 m/s²
Vx= V * cos(54º) = 38.8 ft/s
Vy= V * sin(54º) = 53.4 ft/s
<u>PARAMETRIC EQUATIONS:</u>
x(t)= Vx * t
y(t)= Vy * t - (g * t²)/2
Answer:
11.95 dollars
Step-by-step explanation:
Cost of one LED bulb = 6.95 dollars
Cost of changing one bulb = 3 dollars
Life of each bulb = 5 years.
In 10 years, only one time after 5 years the bulbs would have been changed
Hence cost of 100 lamps = 695 and
cost of changing once = 500
Total cost = 1195 dollars for 11 years
Divide this by 10 years to get average cost per year
Cost of 100 lamps per year = 1195/100 = 11.95 dollars
