0.45+0.45= $0.90 + 5.50x2+2.25=$13.25 13.25+0.90 =$14.50 he would get $5.50 back out of the 20$ spent
Answer:
|F net| = 20.22 N
θ ≈ 19.8°
Step-by-step explanation:
F net = 15N i + 8cos(60°)N i + 8sin(60°)N j
= 15N i + 8×½N i + 8×√3/2N j
= 15N i + 4N i + 4√3N j
= 19N i + 4√3N j
|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N
tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°
Step-by-step explanation:
=0.2(2b-15c)
=0.4b-3c
hope it helps.
Distribute 6(x+4) = 8(x-2)
6x+24 = 8x-16 subtract by on both sides
-24. -24
6x = 8x-40 subtract by on both sides
-6x. -6x
2x = -40
divide both by 2 on each side
and X=20
