Hello again. :)
Step 1: Make both fractions have common denominators. (24/60 and 25/60)
Step 2: Add the fractions. (49/60)
Step 3: Subtract 49 from 60. (11/60)
Step 4: The answer is B.
Hope this helps! <span>＼(≧▽≦)／</span>
The answer is c because 8 - 5 is 3.
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
The answer is Y=11, X=-1
Here's my work:
x=-12+y
-6(-12+y)+2y=28
6*12= 72
72 -6y +2y=28 (now we combine like-terms)
72-4y=28 (now divide by -4)
-18+y=-7 (add 18 to both sides)
y=11
next part we find x:
x=-12+(11)
x=-1
Answer:
8 Gauss
Step-by-step explanation:
Since your moving the magnet from 10 to 20cm you're essentially multpliying the distance by 2.
K = 2
Therefore k ^ 3 = 2^3
64/2^3
=8
