daser333 [38]

Answer:

3.33%

Step-by-step explanation:

Factory measure=330 ml

Actual measure=341 ml

Difference between actual measure and factory measure is error

Difference=341 ml-330 ml=11 ml

Error (in ml)=11 ml

Percentage error=100* Error/Factory measure

Percentage error= 100* $\frac {11 ml}{330}%$

Percentage error=3.33%

Therefore, the percentage error in the content is 3.33%

a family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads. each m

mart [117]

The entire family (5 people) save 120 gallons per day.

Subtraction:

Subtraction means we have to find the difference of the numbers.

Given,

A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.

Each member of the family averages 8 minutes in the shower per day.

Here we need to find the entire family savings per day.

According to the question,

The total bath time for the whole family is,

=> 8 x 5 = 40

So for one day,

If the showerheads cost 5 gallon per minute, then the cost for the family is,

=> 40 x 5 = 200

If the showerheads cost 2 gallon per minute, then the cost for the family is,

=> 40 x 2 = 80

So, the savings is,

=> 200 - 80

=> 120

So, they save 120 gallons per day.

First five term for An=n^2-2n

densk [106]

First 5 terms are: -1,0,3,8,15

Step-by-step explanation:

we will put n=1,2,3,4,5 to find first 5 terms of the sequence

Explicit formula for sequence is:

$a_n = n^2-2n$

Putting n=1

$a_1 = (1)^2-2(1)\\= 1-2\\= -1$

Putting n=2

$a_2 = (2)^2-2(2)\\= 4 - 4 \\=0$

Putting n=3

$a_3 = (3)^2-2(3)\\= 9-6\\= 3$

Putting n=4

$a_4 = (4)^2 - 2(4)\\= 16-8 \\= 8$

Putting n=5

$a_5 = (5)^2-2(5)\\= 25 - 10\\= 15$

Hence,

First 5 terms are: -1,0,3,8,15
