Do a sentence, then add a zero at the end of that sentence
Answer:
a. The number of people that receive the text in the fourth round are 10³ people
b. The total number of people that receive the text are 1.1111 × 10⁴ people
Step-by-step explanation:
a. The given information are;
The number of people the text is sent to in the first round = 1
In the second round, the number of people the text is sent to by people in the first round = 10
In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people
In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people
The number of people that receive the text in the fourth round = 10³ people
b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people
The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people = 11111 people = 1.1111 × 10⁴ people
The answer will be 2,900 HOPES this helps. :)
Answer:
A) 49x^2-36 km
Step-by-step explanation:
Remember that speed is equal to distance divided by time. Therefore, if you multiply time with speed, then you get the distance traveled.
So, we will do (7x+6) kph multiplied by (7x-6) hours to get 49x^2-36 km.
