Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away
initially and save $30 every month. The second option is to put $200 away initially and save $50 every
month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
Plzzz hellpppp

Answers

Answer:

After 5 months, she will save the same amount using either option.

She would have saved $450 with either option.

Step-by-step explanation:

Set up expressions to represent the amount of money saved for each saving option, where x is the number of months

The first one can be represented by 30x + 300

The second one can be represented by 50x + 200

Set these equal to each other and solve for x:

30x + 300 = 50x + 200

300 = 20x + 200

100 = 20x

5 = x

So, after 5 months, Tina will save the same amount of money with both options.

To find how much she will save, plug in 5 as x into either expression:

30x + 300

30(5) + 300

150 + 300

= 450

So, she would have saved $450 with either option.

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help

Answers

The answer is 486.6

There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6

Answer:

Step-by-step explanation:

You could do it this way.

How many hours are there in a year?

365 * 24 = 8760 hours.

This camera does not recognize days. It works on hours. Every 18 hours it resets. So

8760/18 = 486  and 2/3 times.

Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.

The answer is 486 times.

2/3 * 24 = 16

The camera would reset 2 hours into the next day.

The third one. O4 (5+4)

Explanation:
4 (5+4)
4 times 5 is 20 which added to 4 times 4 which is 16 is the same thing asked before. 20+16. So the answer is the third one

Answer:

4 (5 + 4)

Step-by-step explanation:

20 + 16

= 4 (5 + 4)

= 4(5) + 4(4)

= 20 + 16

therefore, the answer is 4 (5 + 4)

Answers

Answer:

37

Step-by-step explanation:

It’s 37 degrees. If you look at one straight line, both sides have to equal 180. So take 180-37 and that’s the answer to CBD. Then you take THAT and subtract it from 180, which is 37. That’s the complicated way of explaining it. Since it’s right across it’s 37.

Given sequences e) 2, 3, 6, 18, 108, 1944, ... f) 1, 2, 6, 24, ...To findRecursive formula for the general termSolution

We can observe that

(b^5)^3 x b^4 simplify

b^19x
I hope this helps:D

Answer:

b^19

Step-by-step explanation:

In the first factor, we need to use a formula to simplify. The formula is x^a^b = x^(ab). So that means that our first factor simplifies to b^15. Then we add up the powers to simplify it even more. b^15 * b^4 = b^19 using another formula. Therefore b^19 is the answer.
