Answer:
70 words.
Step-by-step explanation:
Multiply the number of words he can type in one minute (10) by the number of minutes he is typing for (7).
84/2 = 42
42/2 = 21
21/3 = 7
7/7 = 1
84 = 2^2 * 3 * 7
It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.
For the first problem it would take about 2500 revolutions to gover such a distance and in 500 revolutions, it will travel 1539.4 meters.
Answer:
y = -2x + 12
Step-by-step explanation:
The point-slope equation for a line has the following format:
y = mx + b
In which m is the slope and b is the y-intercept(value of y when x = 0).
(1,10)
This means that when x = 1, y = 10. So
10 = m + b
(5,2)
This means that when x = 5, y = 2. So
2 = 5m + b
From the first equation, b = 10 - m. So
2 = 5m + 10 - m
2 = 4m + 10
4m = -8
m = -2
And
b = 10 - m = 10 - (-2) = 10 + 2 = 12
So
y = -2x + 12
