Answer:
70
Step-by-step explanation:
Apparently, you want the ratio of the weights:
(dino weight)/(car weight) = (2.8×10^5)/(4×10^3)
= (2.8/4)×10^(5-3) = 0.7×10^2 = 0.7×100
= 70
The heaviest dinosaur weighed about 70 times the weight of an average car.

Your calculator can do arithmetic in scientific notation. So can any spreadsheet.
The applicable rule of exponents is ...
(10^a)/(10^b) = 10^(a-b)
Answer:
Step-by-step explanation:
We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.
So the number of volunteers that donated blood will be 32-n.
We are also told that the rest of the volunteers donated 470 milliliters each.
To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).
Therefore, each of the volunteers donated
millimeters of blood.
Jay's claim is false. They would have $156.8 left which is 56% of their original combined total.
Answer:

Step-by-step explanation:
0.125 as a fraction is 125/1000 or 1/8
- 1 is the same as
(anything to the power of 0 is 1) - 8 is the same as 2³ (2 × 2 × 2 = 8)
÷ 2³ =
(You subtract the powers: 0 - 3 = -3)
Hope this helps!
Answer:
Position from point A= 383.33 meters
Step-by-step explanation:
A concept to know is that the integral of velocity will give you the distance traveled.

where the interval of integration are the starting time and ending time.
I let the starting time be t₀ = 0, and the ending time t₁=10 for the 10 seconds that it traveled.
I did the integration and got 383.33m traveled in 10 seconds.
So the answer is 383.33 meters.
