Answer:
it would also be 3/4x (in terms of y=mx+c)
Step-by-step explanation:
parallel lines have the same slope/gradient
Answer:
She can buy 3 bracelets.
Step-by-step explanation:
$50 (Total price) - $12 (Airpod case) = $38
$38 - $9.50 (Bracelets) = $28.5
$28.5 - $9.50 = $19
$19 - $9.50 = $9.5
Answer:
X = 149
Step-by-step explanation:
A full circle is 360 degrees
Add 160+51=211
360-211=149
Cos(A-B) = cosAcosB + sinAsinB
<span>
cos(</span>π/2 - θ) = cos(π/2)cosθ + sin(π/2)sinθ
π/2 = 90°
cos(π/2) = cos90° = 0. sin(π/2) = sin90° = 1
cos(π/2 - θ) = cos(π/2)cosθ + sin(π/2)sin<span>θ
</span>
= 0*cosθ + 1*sin<span>θ = </span>sin<span>θ
Therefore </span>cos(π/2 - θ) = sin<span>θ
QED </span>
Yes the square root of 1/4 is a rational number
