Since Grandpa Ernie's height decreased by the same amount each year, we can simply divide the total height decrease of 2.4 cm, by the total number of years, which is 444 years. This gives us:
2.4 cm / 444 years = 0.00541 cm/yr
So Grandpa Ernie's height decreased by 0.00541 cm/yr.
Answer: 10
Step-by-step explanation:
These types of questions involve ratios. So 2.5: 25 is equal to 25 : 250 and all i did was multiply both sides by 10. Then it says that he only has 1 pound of ground beef so 25* 1/25 is equal to one, and then 250 * 1/25 is equal to 10.
Subtract 5 from both sides.
Subtract 8n from both sides.
Divide both sides by -9 to solve for n.
The value of n is
-4/9.
The quickest way for converting small numbers like this to binary would probably be to find the closest power of 2, then add/subtract intermediate powers of 2 as needed.
Converting 8 is immediate, since it's already a power of 2:
Converting 15 and 17 is also pretty easy if you're familiar with the rules of arithmetic in binary.
S = 555 I think I’m not 100% sure
