For finding GCF, just find the least number among them.
For example:
a.) 6x^2 - 9 find what number that can be divided to 6. In this case, it is 2 and 3.
You can't divide 9 by 2 so the answer in this equation would be 3.
b.) 2a^ 2 + 22a + 60 I's just the same method to use. In this case, we will use 2a^2. The factors that can be divided to 2 is (2,1). So we will choose 2 because it is the GCF of 2 and the equation is divisible by 2.
This can be solved by using a simple algebraic equation.
For example, in the first column, Caleb worked 5 hours. We do not know how much he makes per hour, so let that be x. He earned a total of $36.25, so the equation can be written as 5x=36.25.
Divide by 5 on both sides, and you get x= 7.25
He earns $7.25 per hour of work.
Repeat this for all the workers:
Jeremy: 7.5x=65.25
x= $8.70
Maria: 4.25x=34.00
x= $8
Rosa: 8x=54.00
x= $6.75
Jeremy has the greatest hourly rate
Answer total reported cases in the 9th year will be 153600
Step-by-step explanation:
he compounding formula is as:
Here F is the future value
P is the present value
r is the rate at which the infection spreads in a year
n is the total number of years in consideration
Now, we know that the infection started spreading in the previous year and the question asks us How many cases will be reported in the ninth year from now. We will use the formula taking into the consideration that the total number of years is 10.
Thus, in the 9th year from now, the total cases of infection will be:
Thus, total reported cases in the 9th year will be 153600
