The correct statements are:
1. The dinosaur and the mammoth existed after the trilobites.
The trilobites are a species that appeared and existed much earlier than any dinosaur or later mammals like the mammoth. The difference in their existence is few hundred million years, and while the trilobites are primitive life form, the dinosaurs and mammoths are much newer, better evolved species.
3. The trilobites and the armored fish died before the dinosaur.
Before the dinosaurs appeared, there were many other species that lived before them, some of which are the trilobites and the armored fish. The trilobites being one of the oldest species, and the armored fish being a more evolved but still primitive fish with exoskeleton. Both of them existed in periods prior to the dinosaur domination.
Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
Answer:
The Fighting Begins. Fighting began in 1775 in the Northern colonies.
Explanation:
The Lowcountry folks were rich planters, and the Upcountry folks were everyday farmers, tradesmen, and woodsmen. The Upcountry thought the Lowcountry was stuck up, the Lowcountry thought the Upcountry were backwards hillbillies.
The Amount of investment equals $974.83.
The continuous compound interest helps to calculate an investment that are reinvested into the balance over a infinite number of periods.
- The formula for continuous compound interest is A=P^e^(r*t)
Amount of investment = $535 * e^(6%*10)
Amount of investment = $535 * 1.82211880039
Amount of investment = $974.833558209
Amount of investment = $974.83
Therefore, the Option B is correct since the Amount of investment equals $974.83.
