Use the explicit formula an= a₁ + (n-1) d to find the 500th term of the

ivanzaharov [21]

Therefore, the 500th term of the sequence exists 3517.

<h3>How to estimate the 500th term of the sequence?</h3>

The given sequence is 24, 31, 38, 45, 52, ...

It exists an Arithmetic progression.

Here, the First term = 24

Common difference = 31 - 24 = 7

The given explicit formula for the nth term exists

an = a₁ + (n - 1)d

Where a₁ exists the first term, d exists a common difference.

Substitute a₁ = 24, d = 7 and n = 500

a(500) = 24 + (500 - 1)7

= 24 + (499)7

= 24 + 3493

a(500) = 3517

Therefore, the 500th term of the sequence exists 3517.

You need 70 bookmarks for a craft fair you begin with 35 bookmarks and make 10 bookmarks each hour. Write an expression that rep

professor190 [17]

Answer:

70 = 10x + 35 is your equation (10x + 35 is your expression).

3 1/2 hr is the time needed.

Step-by-step explanation:

Let hours = x.

You need 70 bookmarks, you have 35 (constant number), and you make 10 bookmarks an hour (varys).

Set the equation:

70 = 10x + 35

Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract, then divide.

Subtract 35 from both sides:

70 (-35) = 10x + 35 (-35)

70 - 35 = 10x

35 = 10x

Isolate the variable (x). Divide 10 from both sides:

(35)/10 = (10x)/10

x = 35/10

x = 3.5

3 1/2 hours is your answer.

Whats the difference between a subset and a proper subset? {5,8} {2,5,8} Is {5,8} a subset of {2,5,8}.

valina [46]

Answer:

$\{5,8\}$ is a subset of $\{2,5,8\}$

Step-by-step explanation:

Required

Difference between subset and proper subset

To answer this question, I will use the following illustration.

$A = \{1,2,3\}$

$B = \{2,3\}$

$C = \{1,2,3\}$

In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.

Set C is a subset of A because $A = C$

Using the above illustration, we have:

$\{5,8\}$ and $\{2,5,8\}$

$\{5,8\}$ is a subset of $\{2,5,8\}$ , because 5 and 8 are in $\{2,5,8\}$ but 2 which ca be found in $\{2,5,8\}$ is not in $\{5,8\}$

The school that Trevon goes to selling tickets to the annual dance competition. On the first day of tickets sales the school sol

KiRa [710]

Answer:

both kinds of tickets are $5 each

Step-by-step explanation:

Let s and c represent the dollar costs of a senior ticket and child ticket, respectively. The problem statement describes two relationships:

12s + 5c = 85 . . . . . revenue from the first day of sales

6s + 9c = 75 . . . . . . revenue from the second day of sales

Double the second equation and subtract the first to eliminate the s variable.

2(6s +9c) -(12s +5c) = 2(75) -(85)

13c = 65 . . . . . simplify

65/13 = c = 5 . . . . . divide by the coefficient of c

Substitute this value into either equation. Let's use the second one.

6s + 9·5 = 75

6s = 30 . . . . . . . subtract 45

30/6 = s = 5 . . . divide by the coefficient of s

The price of a senior ticket is $5; the price of a child ticket is $5.
