Answer:

  d)  geometric; r = 4

Step-by-step explanation:

Differences of adjacent terms are not constant (they are 1.2, 4.8, 19.2, ...), so the sequence is NOT ARITHMETIC.

Ratios of adjacent terms are constant (they are 1.6/0.4 = 6.4/1.6 = 25.6/6.4 = 4), so the sequence is geometric with a common ratio of 4.

An electrician needs to run a cable from the top of a 40​-foot tower to a transmitter box located 30 feet away from the base of
grin007 [14]
The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c

You make $5000 per morth. If you spend 50% on necessitles, 30% on stuff you want and 20% of it you end up saving, how much money
liubo4ka [24]

Answer:

$1000 per month

Step-by-step explanation:

5000 dollars is 100 percent so we put 5000 over 100

5000/100

then since we need to find 20 percent of something, we put x over 20

x/20

Then we cross multiply

<u>5000</u>      times       <u>x   </u>            

100                        20

so 100x = 100000

and x = 1000

Good luck, and hope I did this correctly
