The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180

The nth term of an arithmetic sequence is expressed as:

Tn = a +(n - 1)d

where

If -4 is the first term and 10 is the third term, then;

a = -4

a + d = 10

d = 10 - (-4)

d = 14

Determine the 157th term

T157 = -4 + (157 - 1)(14)

T157 = -4 + (156*14)

T157 = 2180

Hence the 157th term of the sequence is 2180

Answer:

5x = 5(10) = 50 inches

Step-by-step explanation:

Let x = length of shorter piece  then

5x = length of the longer piece

.

x + 5x = 60

6x = 60

x = 10 inches (shorter piece)

.

Longer piece:

5x = 5(10) = 50 inches

Answer:

22 grams

Step-by-step explanation:

Divide the number of minutes by the half life...    2/1=2

Multiply starting amount by one-half (1/2) a total of the number of half-lives that have passed. ( 2 half lives in our case)

88 * 1/2 *1/2 = 22 grams     also written as 88(1/2)^2

Answer:

Step-by-step explanation:

If the bricklayer can construct the wall in its entirety in 3 hours, then he can get 1/3 of the job done in an hour.

If the apprentice can get the whole job done in 5 hours, then he can get 1/5 of the job done in an hour. If they both work together on said job, the equation is

[tex]\frac{1}{3}+\frac{1}{5}=\frac{1}{x}[/tex] and now we solve for x. Multiply everything by the LCM to get rid of the fractions. That would be 15x:

[tex]15x(\frac{1}{3}+\frac{1}{5}=\frac{1}{x})[/tex] and doing that gives us

5x + 3x = 15 and

8x = 15 so

x = 1.875 hours which is 1 7/8 hours which is also 1 hour and 52 1/2 minutes.

Answer:

I'm pretty sure it is D

Step-by-step explanation:

sry if I am wrong

The fourth graph is representing the inequality x ≤ 7, so option D is correct.

Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal.

Given:

The inequality = x ≤ 7,

As this inequality representing the value of x is less than 7 or can be equal to 7, In this graph

Option D is representing the inequality, as the graph is suggesting x can be equal to 7 or less than 7.

Therefore, the fourth graph is representing the inequality x ≤ 7.

Answer: $19.02

Step-by-step explanation:

First find the sales tax paid. It will be paid on the cost of the meal:

= 14.20 * 8%

= $1.14

Then find the tip which was done after the sales tax was added:

= 24% * (14.20 + 1.14)

= 24% * 15.34

= $3.68

The total cost is:

= Gross amount + Sales tax + tip

= 14.20 + 1.14 + 3.68

= $19.02

0.8k - 20 = -60

Step 2: Solve for k

Answer:

k = - 50

Step-by-step explanation:

0.8 k - 20 = - 60

Add 20 to each side

0.8 k - 20 + 20 = - 60 + 20

0.8 k = - 40

divide each side by 0.8

0.8 k / 0.8 = -40 / 0.8

Answer:

$1200 should receive.

Step-by-step explanation:

To check whether to receive $1500 or $1200 just find the present values of each amount.

Present value of annuity $1500:

Present value of annuity = Annuity (P/A, 7%, 12)

Present value of annuity = 1500 (P/A, 7%, 12)

Present value of annuity = 1500 (7.9426)

Present value of annuity = $11913.9

Present value of annuity $1200:

Present value of annuity = Annuity (P/A, 7%, 20)

Present value of annuity = 1500 (P/A, 7%, 20)

Present value of annuity = 1500 (10.5940)

Present value of annuity = $15891

Thus, $1200 should receive.
