Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

Ron wants to buy a video game with a selling price of ?$36?, on sale for? 50% off. The sales tax in his state is 5.5 %. How much

cestrela7 [59]

Answer:

Yes, it costs $18.99.

Step-by-step explanation:

The game is originally $36 and a game 50% off is 36/2 = $18.

The sale price is $18.

The state charges 5.5% tax which means you pay 105.5% of the sale price.

1.055(18) = 18.99

The final total is 18.99 which means Ron's $19 is enough.

If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.

Leto [7]

Answer:

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

$x=\dfrac{k}{y}$ , k is constant of proportionality

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

$y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6$

So, the value of y is 6 when x is 5.

as Saturn revolves around the sun, it travels at a speed of approximately 6 miles per second. convert this speed to miles per mi

3241004551 [841]

Given:

Speed = 6 miles per second

If the Saturn revolves 6 miles in 1 second then the speed is:

$\begin{gathered} In\text{ 1 second distance is 6 miles} \\ So\text{ in 60 second distance is =6}\times60\text{ miles} \\ =360 \end{gathered}$

So speed in minutes is 360 miles per min.

In 3 minutes traveling distance is:

$\begin{gathered} =360\times3 \\ =1080 \end{gathered}$
