Answer:
27 days
Step-by-step explanation:
It is a simple division question
18 / (2/3)
Multiply by reciprocal
18 * 3 / 2 = 27
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:
20.31 units to the nearest hundredth.
Step-by-step explanation:
We need to use the distance formula between the points and find their sum.
D1 = √((2-2^2 + (1+3)^2) = √16 = 4
D2 = √(-1-2)^2 + (3-1)^2) = √13
D3 = √(-3+1)^2 + (0-3)^2) = √13
D4 = √(-3+3)^2 + (-4)^2) = √16 = 4.
D5 = √(-3-2)^2 + (-4+3)^2) = √26.
Perimeter = D1+D2+D3+D4+D5
= 4+√13+√13 + 4 +√26
= 20.31 units.
