Answer:
2,4, and 8.
Step-by-step explanation:
If the population has a doubling time of 25 years, that means that in 25 years the population will double. So for 25 years, the factor will be 2. For 50 years, the factor would be 2x2, which is 4. For 100 years, it is 4x2 which is a scale factor of 8.
Answer:
The volume is 191.3 
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by the formula:
where B is the area of the pyramid's base, and H its height. So, in our case, the base is a square of length 7.5 cm, which gives 56.25 cm^2
Now, we use this value and the height 10.2 cm to find the volume:
which rounded to the nearest tenth is: 191.3
Answer:
C) 55 degrees
Step-by-step explanation:
You need the following geometry definition.
<u><em>Definition:</em></u>
<em>The measure of an arc of a circle is equal to the measure of the central angle that intercepts it.</em>
Angle AOB is a central angle since its vertex is the center of the circle.
According to the theorem above, the measure of arc AB is the same as the measure of central angle AOB.
measure of arc AB = measure of angle AOB
measure of arc AB = 55 degrees
Answer: C) 55 degrees
