The height of emperor penguin is 120 cm and height of galapagos penguin is 49 cm
<em><u>Solution:</u></em>
Given that The largest species of penguins is the emperor penguin. One of the smallest is the Galápagos penguin
<em><u>To find: height of each penguin</u></em>
From given question,
Let "e" be the height of emperor penguin
Let "g" be the height of galapagos penguin
Total height of two penguins = 169 centimeter
Therefore,
height of emperor penguin + height of galapagos penguin = 169
e + g = 169 ---- eqn 1
The emperor penguin is 22 centimeters more than twice the height of the Galápagos penguin
height of emperor penguin = 22 + 2(height of galapagos penguin)
e = 22 + 2g --- eqn 2
Let us solve eqn 1 and eqn 2
From eqn 1,
g = 169 - e ------- eqn 3
Substitute eqn 3 in eqn 2
e = 22 + 2(169 - e)
e = 22 + 338 - 2e
e + 2e = 360
3e = 360
<h3>e = 120</h3>
Thus from eqn 3,
g = 169 - 120
<h3>g = 49</h3>
Thus height of emperor penguin is 120 cm and height of galapagos penguin is 49 cm
Answer:
282.7
Step-by-step explanation:
Surface area of Cylinder is 2πr(r+h).
Which in this case is 2π3(3+12) = 282.7 yd^2
Answer:
the answer is B
Step-by-step explanation:
It's a pentagonal pyramid.
Answer:
a. $ 1.11
b. $ 0.08
Step-by-step explanation:
a. The volume of the ball is the volume considering all it (1.2 in diameter) less the volume considering the 0.4 in thick.
V = (4/3)πrb³ - (4/3)πrt³
Where rb is the radius of the ball (0.6 in) and rt is the thick (0.4 in)
V = (4/3)π(0.6)³ - (4/3)π(0.4)³
V = 0.637 in³
For 50 balls, the volume is 50*0.637 = 31.85 in³
So, the cost to produce 1 case is:
$0.035/in³ * 31.85 in³ = $ 1.11
b. The profit is the difference between sales and cost, so for one ball:
P = 0.10 - 0.035*0.637
P = $ 0.08
