Answer: Multiplication
Step-by-step explanation: The M in PEMDAS stands for Multiplication
Imagine that we know the volume of the Earth, which is 1.08 x 10**12 km3
And we model the Earth as a perfect Sphere.
We know that the volume of the sphere is V = 4/3 * pi * (r**3)
We can solve for r......................r = cube root((V*3/4)/pi)
r = 6364,71 km , which is a good approximation for the radius of the Earth!
Answer:
It would be length x width so I'mma say it's 40cm
Step-by-step explanation:
length 7cm+2cm+1cm=10cm
width 2cm+2cm=4cm
length × width
10×4=40
40cm
Answer:
Third step has mistake
Step-by-step explanation:
It should be as follows:
8x = 10
It is given that the third terms is obtained by multiplying the second term by 2 and then adding 3:
Since the third term is 17, we have
And then again, the second term is obtained by multiplying the first one by 2 and then adding three:
Solve this equation for 
and you'll get the answer
