Answer:
I'm pretty sure the answer is A!
Step-by-step explanation:
cause the first shower head is 5x3=40 and the second one is 3×8=24 so you that the answer and find the difference leaving you with the number 16!
Answer:
Step-by-step explanation:
Hi there!
The two angles given are opposite angles, meaning that they are angles opposite of each other at an intersection.
Opposite angles are always equal:
Combine like terms:
Divide both sides by 6 to isolate <em>x</em>:
I hope this helps!
21/24
Divide 21 by 3. You get 7.
Divide 24 by 3. You get 8.
7/8 is your answer
How does your figure look like?
We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd
