250 and - 1250

This is a geometric sequence with common ratio r = - 5

multiply each term by - 5 to obtain the next term

- 50 × - 5 = 250

250 × - 5 = - 1250

the sequence is - 2, 10, - 50, 250, - 1250

Molly opened a bank account. She deposited $86.50 into her account every month for 20 months. She used $24.50 every month to pay

anastassius [24]

She spent $310 on the singing camp.

MY WORK:

I multiplied $86.50*20 because $86.50 is the amount she deposited for 20 months. $86.50*20=$1740.00

Then I multiplied $24.50*20 because she spent $24.50 for 20 months. $24.50*20= $490.00

Then I subtracted $1740.00-$490.00 because she spent $490 out of her bank account. $1740.00-$490.00=$1240.00

Finally, because its 1/4 of her money, I divided $1240.00 by 4. $1240 divided by 4= $310

Hope this helps!!

Which coordinate grid shows Point A at (0.50, −1.25)? (1 point)

polet [3.4K]

9514 1404 393

Answer:

(d) see below

Step-by-step explanation:

Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...

A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares

Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.
