Answer:
Alex walked more
Step-by-step explanation:
Jenna: 12/5= 2.4
alex: 15/6=2.5
30% = 3/10
Number of hours you sleep = 24hours × 3/10
= 24hours ÷ 10 × 3
= 2.4hours × 3
= 7.2hours
Hope this helps! :)
The answer would be -11,661. This can be found by multiplying 36 and 9 then multiplying that by 36. You'd then subttact that answer to 3. I hope this helps.
Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: <em>N + 9</em>
N is equal to 12 in this equation
<em>12 + 9 is 21.</em>
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is <em>12(12)= </em>144
Hope this helps!
(By the way, I'm horrible at math so this could be completely wrong)
Answer:
4√6
Step-by-step explanation:
The line marked x meets the base of the isosceles triangle at its midpoint, so dividing the triangle into two congruent right triangles with leg 5 and hypotenuse 11.
The Pythagorean theorem can be used to find x:
5² + x² = 11²
x² = 121 -25 . . . . . . subtract 25 from both sides of the equation
x = √96 . . . . . . . . . take the square root
x = 4√6 . . . . . . . . . simplify the radical
