Answer:
We are expected to find 1,080,000 right handed people in that group of people
Step-by-step explanation:
In this question, we are given the ratio of right handed to left handed people and we are asked to calculate the number of right handed people we can find in a given population.
First, we check the ratio given.
The ratio is said to be that of left handed individuals to right handed individuals and this sits at 2 to 9.
Thus out of 1,320,000 people , the number of right handed individuals will be ;
9/(2+9) * 1,320,000
9/11 * 1,320,000
= 1,080,000 people
Answer: 315 ft
Step-by-step explanation: The length of a rectangle is length times width, so 21 (length) times 15(width) is 315 ft.
Catherine could take the original price of $144.97 and multiply it by .09 (9%). This would equal a sales tax of $13.073 which could be rounded to $13.01. Then add the original price of $144.97 to the tax of $13.01 to get a total of $157.98.
a = 9
Step-by-step explanation:
We are given -12 = -2a +6
so to find the value of a,
move 6 from rhs to lhs by changing its sign
rhs = right hand side
lhs = left hand side
-12 - 6 = - 2a
-18 = -2a
dividing -18 by -2, we get a = 9
Hence, a = 9 is the required answer.
