If you meant to write this;Nisha and Marcie Drive 20 miles from their sisters to hoodoo to go skiing. The speed limit is 55 miles per hour. It snowed all night, and the safe speed to drive is 40 miles per hour. Explain how you can determine how many more minutes it takes to drive 20 miles at 40 miles per hour in a 55 miles per hour zone.
If you drive 20 miles at 40 mile per hour, then 20 miles divided by 40 miles equals .5.5 times 60 minutes (one hour) is 30 minutesIf you drive 20 miles at 55 mile per hour, then 20 miles divided by 55 miles equals .3636.3636 time 60 minutes (one hour) is 21.8 minutes30 minutes at 40 mph minus 21.8 minutes at 55 mph is 8.2 minutes faster

Answer:
<u>For one Necklace you would need...</u>
24 blue beads.
16 white beads.
4 green beads.
Ratio: 24: 16: 4
Step-by-step explanation:
If you quadruple the amount of beads from the original amount (6 : 4: 1), the total beads for that necklace will be 44.
Step 1: 6 x 4 = 24 (amount of blue beads in necklace).
Step 2: 4 x 4 = 16 (amount of white beads in necklace).
Step 3: 1 x 4 = 4 (amount of green beads in necklace).
Now check to see if the total of all types of beads sum up to 44:
Step 4: 24 + 16 + 4 = 44
______________-
There is your answer:
You need 24 blue beads, 16 white beads, and 4 green beads to have a total sum of 44 beads in that one necklace.
Wouldn't you divide? If so, 5/9 = 0.6
