Answer:
Yes
Step-by-step explanation:
First you take off 33%, then add the sales tax, in this case the price with the discount is $703.50, the you multiply that by 1.07 and get your answer with tax and discount of $752.75 ( when you round up)
50+75= 125$
125 divided by 65 = 1.92
1.92 rounds up to 2, so it would take approximately 2 hours.
If you need to find an exact number then we need to find a number greater than 125 that both 50 and 65 can fit into.
125+ 50 + 50 + 50 + 50= 325
325 divided by 65= 5
So it would take 4 hours of work with Abe to cost 325 and 5 hours of work with the other service.
Answer:
184.
Step-by-step explanation:
p(x) = 2x^4 + 6x^3 - 3x^2 + 24
Whet x = 2:
p(2) = 2(2)^4 + 6(2)^3 - 3(2)^2 + 24
= 2*16 + 6*8 - 3*4 + 24
= 32 + 48 - 12 + 24
= 92.
Together they spent 184.
Sin 10° Sin 50° sin 70° = 1/8
Now we multiply upper & bottom both side 2/2
then
➡ 1/2 (2sin 10° sin50° 70°)
➡ 1/2 sin10°( 2sin70° sin50°)
we know that
2 sinA sinB = cos (A-B) - cos (A+B)
Then
➡ 1/2 sin 10° ( cos 20° - cos 120°)
➡ 1/2 sin 10° ( cos 20° - cos (90°+30°))
➡ 1/2 sin 10° ( cos 20° +1/2)
➡ 1/2 sin 10° cos 20° +1/4 sin 10°
again we multiply both upper & bottom side 2/2 so
➡ 1/4 ( 2 sin 10° cos 20°). + 1/4 sin 10°
we know that
2 sinA cos B = sin (A+B) - sin (A- B)
➡ 1/4 (sin 30° - sin 10°) + 1/4 sin 10°
➡ 1/4 sin 30° - 1/4 sin 10° + 1/4 sin 10°
we know sin 30° = 1/2
➡ 1/4 × 1/2
➡ = 1/8 hence proved
