Answer:
C
Step-by-step explanation:
S= (2M-15)=185
2m=185+15= 200
m=200÷2= 100cm-C
Answer:
40.07 and 40.070...
Step-by-step explanation:
(4×10)+(7×1/100)
40+0.07
40.07 or 40.070(as the extra zeros don't count)

156-79=77 beads
Answer:
n=3
Step-by-step explanation:
5n+5=20
First you subtract 5 from both sides:
5n+5=20
-5 -5
5n=15
Then divide both sides by 5 to get n by itself.
5n=15
/5 /5
n=3
Answer:
x = <1,5>
y = <-5,1>
Step-by-step explanation:
Let x, y be two vectors in 2D
defined as:
x = <a, b>
y = <c, d>
for x, y to be orthogonal, we know that their dot or scalar product must be zero so,
x . y = 0
<a, b> . <c, d> = 0
a*c + b*d = 0 ------ (A)
Now, consider any four values for a, b, c, and d respectively which satisfy the equation (A)
i.e. I chose (you can choose on your own choice):
a=1, b=5, c=-5, d=1
Verifying Equation (A):
(1)*(5) + (-5)*(1) =0
5 - 5 = 0
0 = 0 (True)
Therefore,
Our vectors x, y are:
x = <1, 5>
y = <-5, 1>
