Nth sequence term question

1 answer:

6 0

One example is when n is 11. 11^2 + 4 = 125. 11 is odd but the 11th term of the sequence, 125, is not prime because 125 is divisible by 5 and 25.

The number of apples in a box decreased from 150 to 135. What is the percent decrease of the number of apples in the box?

goblinko [34]

Answer:

10% decrease

Step-by-step explanation:

The formula for percent change is:

$\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100$

Therefore, for this example:

$\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100=\frac{135-150}{150} \times 100=-10\%$

The negative value indicates that the change was a decrease. Therefore, there was a 10% decrease.

Eddi Din [679]

Answer:

x = $\frac{9}{80}$

Step-by-step explanation:

Given

x + $\frac{9}{20}$ = $\frac{9}{16}$

Multiply through by 80 ( the LCM of 20 and 16 ) to clear the fractions

80x + 36 = 45 ( subtract 36 from both sides )

80x = 9 ( divide both sides by 80 )

x = $\frac{9}{80}$
