Answer:
6.49 × 10⁷ years
Step-by-step explanation:
For Dinosaurs
Dinosaurs have been extinct for about 6.5×10 exponent seven years
6.5 × 10⁷ years
For Neanderthals
Neanderthals have been extinct for about 3.0×10 exponent four years
= 3.0 × 10⁴ years
How many longer is calculated by Subtraction
6.5 × 10⁷ years - 3.0 × 10⁴
= 64970000 years
= 6.49 × 10⁷ years
Answer:
Step-by-step explanation:
The last three are irrational but I'm not sure about the first four.
If 5000 gets increased by 200, then you end up with 5200.
if 900 gets increased by 200, then it'd be 1100.
so in short, if we take 5200 to be the 100%, what is 1100 in percentage from it?
ANSWER
The car moves at 32 mi/hr
EXPLANATION
This question is asking us to determine how fast is a train that makes 330 mile trip in 4 hours.
This is the same as calculating the speed of the train:
Speed = distance covered/time taken
The distance covered is 330 mile
The time taken is 4 hours.
Speed =330/4 =82.5 mi/hr
Answer: -3
Step-by-step explanation:
If you find where the line crosses the y-axis, and count to the next official and visible vertex, you will get 3 up or down, over 1 left or right. It's called rise over run. And as the line is drawn from the left to right side, it's a negative line.
