A geologist has 10 rocks of equal weight. If 6 rocks and a 10-ounce weight balance on a scale with 4 rocks and a 22-ounce weight , what is the weight of one of these rocks in ounces ?

Weight of each rock is 14.8 ounces.

Step-by-step explanation:

Given,

Total number of rocks = 10

6 rocks weigh 10 ounce each

4 rocks weigh 22 ounce each.

To find the the weight of each rock.

Now,

Weight of 6 rocks = 10×6 ounces = 60 ounces

Weight of 4 rocks = 22×4 ounces = 88 ounces

So,

Weight of 10 rocks = 88+60 = 148 ounces

Hence,

Weight of each rock = 148÷10 = 14.8 ounces.

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
