I’m pretty sure 3+9/4 is correct
I also think that is b but it could be d
Answer:
45.72 cm
Step-by-step explanation:
Given: Height of the Chinstrap Penguin= 68.58 cm
Height of the Emperor penguin= 1.143 meter
Lets calculate the height of Emperor penguin in centimeter.
Remember, 1 meter = 100 centimeter
∴ Converting the unit of height of Emperor penguin.
∴ Height of Emperor penguin is 114.3 cm.
Now, comparing the height of Chinstrap penguin and Emperor penguin´s height.
∴ The Emperor penguin is 45.72 cm taller than Chinstrap penguin.
Answer:
t = 40/3 (exact)
t = 13.3 (decimal)
t = 13 1/3 (mixed number)
Step-by-step explanation:
Simplify 4 (t + 5) + 2 (t + 5).
6t + 30 = 110
Move all terms not containing t to the right side of the equation.
6t = 80
Divide each term by 6 and simplify.
t = 40/3
The result can be shown in multiple forms.
t = 40/3 (exact)
t = 13.3 (decimal)
t = 13 1/3 (mixed number)
The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.
The formula to calculate speed is Speed = distance/time.
So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.
