Answer:
5/9 is an example of rational number.
Step-by-step explanation:
as the definition of rational number is the number in the form of p/q but the value of denominator q should not be equal to 0. Every integer is a rational number.
Answer:
Measure of central angle is 3.665 radians
Step-by-step explanation:
In this question, we are trying to get the value of the central angle.
As we can see, the radius of the circle is 12cm while the length of the major arc is 14 pi cm.
Mathematically the length of an arc is calculated as follows;
Length of arc = theta/360 * 2 * pi * r
Plugging the values we have from the question;
14 pi = theta/360 * 2 * pi * 12
divide both sides by 2pi
7 = theta/360 * 12
360 * 7 = 12 theta
theta = (360 * 7)/12
theta = 210
Since 1 degree = pi/180 radian
it means 210 degrees = 210 * pi/180 = 3.665 radians
B. 13 sq feet.
There are 2 ways to solve this.
1. Count the blocks.
2. The shape is 3 blocks length and 4 blocks width. Multiply 3x4, and add the 1 other block.
Answer:
W = 45000 - 780h
Step-by-step explanation:
There were 45000 gallons of water in the swimming pool initially.
Given that at a constant rate i.e. 780 gallons of water per hour is being drained out of the swimming pool.
When the pool has no more than 15,000 gallons of water remaining a chemical additive must be added with water.
Therefore, the equation that gives the remaining water after h hours in the pool is
W = 45000 - 780h (Answer)
