Meg wants to find hie nany phones the company activated in one minute explain why meg can use 15000 divided by 50 to
1 answer:
Answer:
300 phones the company activated in one minute
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Step-by-step explanation:
Here is the correct question: Meg wants to find how many phones the company activated in one minute. Explain why meg can use 15000 divided by 50 to find the answer.
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
Therefore, in the above question Meg knew the number of total phone activated by company in 50 minutes, which is 15000.
Now, she want to find how many phones the company activates in one minute.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Phones the company activated in one minute=
∴ 300 phones the company activated in one minute.

The probability that a grain of rice dropped onto the circles at random lands outside the circle with the 4-cm radius and inside the circle with a radius of 8 cm is or 75%.
Step-by-step explanation:
Step 1:
First, we need to calculate the areas of both circles.
The area of a circle where r is the radius of the circle.
The inner-circle has a radius of 4 cm.
The area of the inner circle
The outer circle has an inner radius of 4 cm and an outer radius of 8 cm.
So its area is where R is the outer radius and r is the inner radius.
The area of the outer circle
So the inner circle has an area of 50.264 square cm and the outer circle has an area of 150.792 square cm.
Step 2:
To find the probability of an event we divide the number of favorable outcomes by the total number of outcomes.
The total number of outcomes is the area of the entire circle
square cm.
The number of favorable outcomes is the area of the outer circle i.e. 150.792 square cm.
The probability of the rice falling in the outer circle .
Answer:
The smallest power of 10 that will exceed is
.
Step-by-step explanation:
We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:
,
Where:
- Integer part, formed by a digit, which is of the highest order.
- Decimal part, formed by a digit onwards.
- Power grade.
The smallest power of 10 that will exceed M is
If , then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of
in scientific notation is:
Then, the smallest power of 10 that will exceed is
.
