Answer:
4050 cm²
Step-by-step explanation:
This is a question of scale factors:
The radius of the larger circle is 9× that of the smaller circle;
This is the linear scale factor of the enlargement of the smaller to larger circle;
The scale factor of the area pertains to 2 dimensions so the scale factor will be the square of the linear scale factor, which is:
9² = 81
The area of the larger circle is found by the area of the smaller circle multiplied by this number:
50 × 81 = 4050
Answer:
Reasoning, Decision making
Step-by-step explanation:
The reasoning is the process of mental. In the process, reasoning needs a reason for establishing the facts. This is a cognitive process. All people engage in reasoning due to their ability to introspection. The reasoning is different in every field in every aspect.
The cognitive process plays a role in both reasoning and decision making. These both are the sub-field creative thinking. Many factors create a barrier in decision making such as incomplete information, emotional and physical resources.
Thus when we may not know the consequences we used both reasoning and decision making.
Answer:
<em>y = -2</em>
Step-by-step explanation:
Since the line is horizontal, all points have the same y-coordinate, -2. The y-intercept is the point (0, -2), so b = -2. The line is horizontal, so the slope is m = 0 which is given.
Use the slope-intercept form of the equation of a line and plug in the information you have.
y = mx + b
y = 0x + (-2)
y = -2
Answer:
842 rounded to the nearest ten is 840
Step-by-step explanation:
Answer:
158 natural numbers
158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721. Step-by-step explanation: Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself.
Hope this helps, have a wonderful day/night, stay safe, happy holidays, and merry christmas!
