Based on their observation of the fossils now found widely spaced across the globe, scientists inferred that the landmass split apart.
What is a fossil?A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are generally considered to be prehistoric in nature.
This simply means that, fossils are obtained by scientists from ancient organisms such as Australopithecus, which is an ape that has the capability to walk on two (2) feet like humans, and it lived in trees.
In this context, scientists inferred that the landmass for organisms that lived on the same early Earth landmass was split apart based on their observation of the fossils, which are now found widely spaced across the globe.

The questions on a test consist of 10 multiple choices, 3 essays, and 9 free responses. If the questions are ordered randomly, what is the probability that the first question is a free response?
Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
10 + 3 + 9 = 22This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
9/22 = 0.409Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.

A stop sign is in the shape of regular octagon. What is the measure of each of the interior angles of the stop sign?
Answer: 135 degrees
Explanation:
The measure of an interior angle of any polygon is (n-2)*180/n, where n is the number of sides in the polygon.
Since the stop sign is an octagon, there are 8 sides, so we can plug in 8 for n.
Therefore, the measure of each interior angle is (8-2)*180/8
= 6*180/8
= 1080/8
= 135 degrees
What is a major division between gravity and the electromagnetic force on one hand and the nuclear forces on the other?(1 point).
Gravity is force present between masses while electromagnetic forces are found between charges.
Nuclear forces are short range while electromagnetic forces are long range.
Electromagnetic force Vs Nuclear forceNuclear force are short ranged while electromagnetic forces cover a wider range, it is dependent on the charges present. Unlike charges attract each other while like charges repel each other in electromagnetic forces.
Nuclear forces occur in the nucleus of an atom and it an attractive force. unlike electromagnetic forces nuclear force do not repel.
Hence we can conclude that ; Gravity is force present between masses while electromagnetic forces are found between charge and Nuclear forces are short range while electromagnetic forces are long range.

Buzz appliances manufactures two products: food processors and espresso machines. The following data are available: food processors espresso makers sales price $125 $225 variable costs $80 $190 the company can manufacture either two food processors per machine hour or three espresso machines per machine hour. The company's production capacity is 1,600 machine hours per month. To maximize profits, what product and how many units should the company produce in a month (assuming unlimited demand for both products)?
In order to maximize profit, 4800 Expresso machines and 0 food processors should be produced.
How to maximize profitFrom the information given, the contribution margin per hour for Expresso makers will be:
Sales price = $225
Less: Variable cost = $190
Contribution margin = $35
Units per hour = $3
Contribution margin per machine hour = $35 × 3 = $105
Also, the Contribution margin per machine hour for food processor is $90.
Number of units available = 1600
Units per machine hour = 3.
Units to manufacture = 1600 × 3 = 4800
Therefore, to maximize profit, 4800 Expresso machines and 0 food processors should be produced.

How long will it take to go 150,000 meters traveling at 50 km/hour?
Answer:
3 hours
Explanation:
1. Convert 150,000 meters into kilometers - 150,000 ÷ 1000 = 150 kilometres
2. Use the equation: time = distance ÷ speed
3. Substitute in the known values: time = 150 km ÷ 50 km/h = 3 hours
Hope this helps!
Answer:
3 hours
Explanation:
First, you have to convert meters to kilometers.
150,000 meters ⇒ 150 kilometers
Then you divide 150 by 50 and see what you get:
150 ÷ 50=3
It will take 3 hours to go 150,000 meters at 50 km/hour

A 60 g ball is tied to the end of a 70 -cm-long string and swung in a vertical circle. The center of the circle, as shown in the figure,(figure 1) is 150 cm above the floor. The ball is swung at the minimum speed necessary to make it over the top without the string going slack.
The tension in the string an instant before it broke is; T = 0.86 N
What is the Tension in the string?
We are given;
mass of ball; m = 60 g = 0.06 kg
Length of string; L = 70 cm = 0.7 m
Height the ball reaches; h = 150 cm = 1.5 m
From Newton's equation of motion;
v² - u² = 2as
where v = 0 m/s Thus;
-u² = 2(-9.81 * (1.5 - 0.7)
u² = 15.696
u = √15.696
u = 3.17 m/s
Thus, tension is;
T = mu²/L
T = (0.06 * 3.17²)/0.7
T = 0.86 N
