Step-by-step explanation:
Based on the fact that the sides of the rectangle are in the ratio 5:2, the length of each side is 20cm and 8cm.
<h3>What is the length of each side?</h3>
Based on the ratio, we can assume the a value of x for the perimeter to be:
Perimeter = 2 x ( length + width)
= 2 x (5x + 2x)
= 2 x 7x
= 14x
The value of x is:
56 = 14x
x = 56/14
= 4
The value of the sides are:
= 5 x 4
= 20 cm
= 2 x 4
= 8 cm

Answer:
B is Geometric and its next terms are 81, 243, 729...
See example below to complete other problems.
Step-by-step explanation:
Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.
Example: 27-9= 18 27/9 = 3
9-3 = 6 9/3 = 3
etc. Common ratio of 3

bolts of length more than
, and less than
will be destroyed
= 13.20 cm and 12.80 cm
<u>Step-by-step explanation:</u>
Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:
A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.
mean length= 
standard deviation= 
2 standard deviation from mean= 
Therefore, bolts of length more than
, and less than
will be destroyed
= 13.20 cm and 12.80 cm
