Answer 1

Answer: Let it be x
200x=80
x=0.4
=40%

Answer 2

Answer:

Answer:

Step-by-step explanation:

divide both by 2

40 percent of 100 is 40

80/200 = .4 or .40 which is 40%

Step-by-step explanation:

-1,-4,-7,-10 write an equation to find the nth term of each sequence. Then find a24

Answers

Answer:

$\boxed {a_(24) = - 70}$

Step-by-step explanation:

According to the following pattern sequence ( $-1, -4, -7, -10$ ), it is Arithmetic Sequence, because every negative number is subtracted by $3$ . So, to find the 24th term, you need to use the Arithmetic Sequence Formula and solve to find the 24th term:

$a_(n) = a_(1) + (n - 1) d$

$a_(n)$ : nth term in the sequence

$a_(1)$ : 1st term

$n$ : term position

$d$ : Common difference

-Apply to the formula:

$a_(24) = -1 - 3 (24 - 1)$

$a_(n) = a_(24)$

$a_(1) = -1$

$n = 24$

$d = -3$

-Solve:

$a_(24) = -1 - 3 (24 - 1)$

$a_(24) = -1 - 3 (23)$

$a_(24) = -1 - 69$

$\boxed {a_(24) = - 70}$

Therefore, the 24th term is $-70$ .

Final answer:

The nth term of the sequence is given by the formula nth term = -1 + (n-1)(-3), resulting in a24 (the 24th term) being -70.

Explanation:

To find the nth term of any arithmetic sequence, you can use the formula: nth term = a + (n - 1)d where a is the first term and d is the common difference. In the given sequence -1, -4, -7, -10, the first term (a) is -1 and the common difference (d) is -3 (because each term is 3 less than the previous term).

So, the nth term formula for this sequence would be

nth term = -1 + (n-1)(-3)

To find the 24th term of the sequence (a24), you would substitute n with 24. So, a24 = -1 + (24-1)(-3) = -70.

What is the total surface area of a right circular cylinder with base radius 7cm and height 12cm.

Answers

Answer:

Using 3.14 for pi

835.24 cm^2

Using the pi button for pi

835.6636459 cm^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi r h

= 2 * pi ( 7)^2 + 2 pi ( 7) * 12

= 98 pi + 168 pi

=266 pi

Which is the best estimate of
11 1/5 and 2 3/4

Answers

I think your question lacks a little bit of information. After a little research, I am able to find that you probably wanted to say '11 1/5 divided by 2 3/4'.

Therefore, I am solving the question assuming that you want to say:

''What is the best estimate of 11 1/5 divided by 2 3/4''.

Answer:

The best estimate of 11 1/5 divided by 2 3/4 will be: 4

Step-by-step explanation:

Given the information

11 1/5 divided by 2 3/4

solving the expression

$11(1)/(5)/ 2(3)/(4)$
