what is the simplest form of 8√5 + √250 - √720? i’ve been crying over this for an hour pls help
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).
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

In 1771, misfortune struck Euler again, when a cataract in his left eye robbed him of his sight entirely. Incredibly, this did not seem to slow him at all. In fact, during his remaining thirteen years, his publishing output accelerated. Of the 886 books and articles he produced in his lifetime – on topics including mathematics, philosophy, mechanics, electricity, astronomy, optics, and music – half of them were completed after total blindness! Use the drop-down menus to complete the statements about Euler's life after he lost his sight. After the cataract took Euler's sight, he . About how many books and articles did Euler complete after he lost his sight entirely?

Answer:
find b: since the triangle is right angle triangle apply the Pythagorean theorem
c²+b²=d²
b²=d²-c²
b²=16²-12²
b²=256-144
b²=112
b=√112 = 4√7the sum of the angle of the triangle=180
( in top Δ abd ) sin Ф=opp/hyp
sinФ=b/d=4√7/16= √7/4 radian
convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees
which makes A= 38 degrees ( adjacent angles are equal when they have common side and do not overlap)find a=?? apply law of cosine
a²= d^2 + c^2 − 2dc cosA
a²=16² + 12²-2(16)(12)cos38
a =√(16² + 12²-2(16)(12)cos38)
a=9.87 rounded to the nearest hundredth(i hope it is right )
6. The complement of an angle is 5 less than four times the angle. Find the measure of the angle.

 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.
If one set of ping pong balls coast 8$ how much does 320 ping pong balls coast?

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.
Which is equal to 75 1/3%
Is √ 256 rational or irrational

If anyone takes vitamins, they will feel better. Bob takes vitamins. Therefore, Bob will feel better. Deductive Reasoning or Inductive Reasoning?
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.
