Robin has a table full of supplies that she will use to decorate picture frames. She decorated one frame with 3 buttons and 12 bows. On her other frames, she also wants to use 2 types of items on each picture frame, but only if the 2 items have the same unit rate as the items on the first frame. Which of the pairs of items could Robin use for the other frames?

Answers

The ratio is 1:4
She could use 4 gems and 16 flowers 4 x 4 = 16 7 stickers and 28 glue dots 7 x 4 = 28

The choices you could pick would be...

4 gems and 16 flowers... because 4 x 4 = 16

7 stickers and 28 glue dots... because 7 x 4 = 28

What is the maximum number of turning points the function f(x)=7x^5+6x^3-4x^2+1 , can have

Answers

The maximum number of turning points of the polynomial is the degree of the polynomial minus 1. In this case the degree is 5, so the maximum number of turning points is 5-1=4.

What is the ratio of 5 hours to 100 minutes

Answers

for this question you should know that 5 hours is equal to 300 minutes so the ratio of 300 minutes to 100 minutes is 300/100 which is equal to 3/1 or 3 :)))
i hope this is helpful
have a nice day 
first 5x60=300
therefore...   300:100
300/50=6   and    100/50=2
6:2
therefore is 3/1
