Simplify both sides then isolate the variable
t=10
Answer:
Step-by-step explanation:
We are to find the equation a line that passes through the point (8, 1) and which is perpendicular to a line whose equation is
.
We know that the slope of line which is perpendicular to another line is the negative reciprocal of the slope of the other line so it will be
.
Then, we will find the y-intercept of the line using the standard equation of a line:
Therefore, the equation of the line will be
.
Answer:
Step-by-step explanation:
Let the area of water is w and area of land is l.
<u>Their ratio is:</u>
or
Find the value of l
- l = 133*3/7
- l = 57 million square miles
7(-3) is an example of multiplication. What the question wants you to do is multiply the outside number (7) by the inside number (-3).
Basically you are just multiplying -3 x 7.
Your product is -21
Answer: The probability is about 0.2%.
The probability of flipping heads one time is 0.5, 50% or 1/2.
To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.
(1/2)^9 = 1/512 or about 0.2%
It should only happen once every 512 times.
