Answer:
5/6 and 75 1/3%
Step-by-step explanation:
8 1/3 = 25/3
25/3 pages of a book in 10 minutes
Multiply both numbers by the reciprocal of 10, which is 1/10
25/3 x 1/10 = 25/30 = 5/6
So, Charlotte reads 5/6 pages of a book in 1 minute.

6. Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each. How many books can she carry in her backpack?
Do not use the equal sign, we're using the greater than sign > and the < less than sign!
Answer:
x≤ 5
Step-by-step explanation:
18-2-1=15
15/3=5
Answer:
the number of book she can carry is 5 books
Step-by-step explanation:
backpack capacity = 18 lb
backpack can carry:
lunch = 1 lb
gym clothes = 2 lb
books = 3 lb per book
find:
how many books can she carry in her backpack?
backpack capacity = lunch + gym clothes + x books
let x be the number of books
18 = 1 + 2 + 3x
18 - 1 - 2 = 3x
15 = 3x
x = 15 / 3
x = 5
therefore, the number of book she can carry is 5 books

Answer:
Deductive reasoning
Step-by-step explanation:
Deductive reasoning is when you make a conclusion based on facts you previously know. These conclusions are correct.
Inductive reasoning is when you use a previously known fact to come up with a general assumption.
Here, we took some previously known facts (If anyone takes vitamins, they will feel better) and made a conclusion that relates fully to that fact. Since Bob took vitamins, he will feel better.
Hope this helped!

Step-by-step explanation:
 death valley located in the United States is 282 feet below sea level is the level of Galilee located in Israel is 682 feet below sea level how much further between the lowest point in death Valley is the lowest point in the Sea of Galilee
Answer:
400 feet.
Explanation:
We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.

Step-by-step explanation:
8√5 + √250 - √720
= 8√5 + (√2)(√5)(√25) - (√5)(√144)
= 8√5 + 5(√2)(√5) - 12√5
= √5 (8 + 5√2 - 12)
= √5 (5√2 - 4)
= √10 (5 - √2).
