87.2 - 25.9 = 87.2 - 26 = 61.2 + 0.1 = 61.3
Answer:
(4x - 6)(y + 1)
Step-by-step explanation:
Group them: (4xy + 4x) (-6y - 6)
Take out the greatest common factor for both:
4x(y + 1) -6(y + 1)
Put it together: (4x - 6) (y + 1) (y + 1)
Since there are two (y + 1)'s, you can get rid of one, giving you:
(4x - 6) (y + 1)
Answer:
$82,000
$66,000 + $4000t
Step-by-step explanation:
Initial annual salary = $66,000
Salary raise per year = $4000
Salary earned after 4 years :
Initial salary + (raise per year * number of years)
$66,000 + ($4000 * 4)
$66,000 + $16,000
= $82,000
Salart after t years :
Initial salary + (raise per year * number of years)
$66,000 +.($4000 * t)
$66,000 + $4000t
You have a right triangle situation here, and what you are looking for is the length of the hypotenuse. The leg perpendicular to the ground is 100, and the base angle that is NOT the right angle, is 65. So your equation is set up like this: sin 65 = 100/x. Rearrange that a bit to get x alone: x = 100/ sin 65. Make sure your calculator is in degree mode and solve for x. x = 110.34 feet of string.
