A rectangle has a length of the cube root of 81 inches and a width of 3 to the 2 over 3 power inches. Find the area of the recta
2 answers:
Answer:
The correct answer is C. The area of the rectangle is 9 inches squared
Step-by-step explanation:
The formula for the area of a rectangle is A =L x W
where L is the length and W the width
we were given the length to be equal to
this can be further simplified to
The width was given to be 3.
This can be further simplified using the law of indices to be =
=
The area A = *
=
=
=
Therefore, the area of the rectangle is 9 inches squared

<h3>What is simplification?</h3>Simplification is to make something easier to do or understand and to make something less complicated.
Given
Carmen simplifies the expression .
We can add x term with x, y term with y, and constant with constant.
On simplifying, we have
Thus, the coefficeint of y is 10.

Answer:
a) 0.7225
b) 0.5220
c) 0.478
It is not unusual.
Step-by-step explanation:
Probability grocery bags are plastic = 85% = 0.85
a) If two grocery bags are chosen at random, the probability that both grocery bags are plastic would be:
b) If four bags are chosen at random, the probability that all are plastic:
Probability all four bags chosen randomly are plastic bags is 0.5220
c) The probability that at least one of four randomly selected grocery bags is paper:
Let's first check for the probability of getting a paper bag.
P(paper bag) = 1 - 0.85 = 0.15
Probability of getting a paper bag is 0.15
Probability that at least one of four randomly selected grocery bags is paper would be:
Since the probability that at least one bag is paper, 0.478 is greater than 0.05, it is not unusual.
