Answer:
b) $52.33
Step-by-step explanation:
(For bid 3 I think you meant $55)
50+52+55 = 157
157/3 = 52.33(.33 repeating)
Which rounds to $52.33
this is system of equations
2x + 5y = -1 times this one by 5 to make the y's opposite
-10x -25y = 5
10x - 25y = -5 (this is it times by 5, now add them)
__________
0 + 0 = 0
now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.
Answer:
I would say angle 6 is supplementary to angle 3.
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Angles 6 and 3 are right angles.
90 + 90 = 180
Hope I helped!
It would be
3.5 × 10⁻³ kg.
The decimal point must be moved 3 places to the right in order to have it behind the first non-zero digit; this gives us the exponent of 3, and since we are moving the decimal to the right, it is a negative exponent.
Answer:
I believe the answer is C. 90 degrees
Step-by-step explanation:
First you find the lengths of the two vectors, which are both 
. Then you find the angle given the cos using: cos(∅)=
= 
= 0. Then using ∅=acos(0)=
= 90°
