75 Ounces Difference????????
100-25=75
I think this is what you asked?<span />
sin x = cos 54 = sin (90-54) = sin 46
Hence x = 46 deg
Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)
81-5x = 21
Or 5x = 60
Or x = 12 deg
hope it helps
Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50
Volume = 5*10*2 = 100 cm³
Densidade = massa / volume
Densidade = 700g / 100 cm³
Densidade = 7g/cm³
Answer:
$14.42
Step-by-step explanation:
Price of Album - $17.00 * .20 = 3.4 (this is the discount)
Then subtract 3.40 from 17.00 to get 13.60
Add the sales tax in by doing $13.60 * 0.06 = $0.82
Add that to the 13.60 to get $14.42 for the total after discount and after tax.
