Answer:

3 cm per hour.

Step-by-step explanation:

180-168= 12, which means 12 cm is gone every 4 hours. To find every hour, we simply do 12 divided by 4, getting 3, which means 3 cm decreases every hour.

On a fruit farm 1/3 of the trees are apple trees and 1/5 are lemon trees. The rest are fig trees. There are 90 trees in all.
Vaselesa [24]

Answer:

I'm not sure what the question was but I've worked out all the three types of trees

Step-by-step explanation:

⅓ + ⅕ = 8/15 because:

×5 ×3

5/15 + 3/15 = 8/15

therefore 7/15 is fig trees

90÷15 =6

6×5 = 30 apple trees

6×3 = 18 lemon trees

6×7 = 42 fig trees

One uranium atom has a diameter of 3.5x10^-8 centimeters. What is the sum of 10,000 uranium atoms'
Vladimir [108]

Answer:

3.5 * 10^-4 centimeters

Step-by-step explanation:

Here, we have one uranium atom having a diameter of 3.5 * 10^-8 centimeters.

We now want to find the sum of 10,000 uranium atoms diameters

Mathematically;

That would be ;

3.5 * 10^-8 * 10,000

But 10,000 = 10^4

Thus, we have

3.5 * 10^-8 * 10^4

= 3.5 * 10^-4 centimeters
