If you had a 15 foot ladder, how far away from the base of a wall would you have to put it to reach a window 12 feet up?

Kruka [31]3 years ago

Answer:

9.000000001

Step-by-step explanation:

If the hypotenuse is  15, the ladder, facing the right angle, and the opposite is 12 we need to use SOH to find the angle.

sin of angle is opposite / hypotenuse

sin of angle is 12 / 15

12/15 = 0.8

sin^-1 of 0.8 = 53.13010235

Angle is that

Then we do this again but a different equation

cos of angle is adjacent (x which we are looking for) / hypotenuse

cos of 53.13... is x / 15

(15 x cos of 53.13... )is x

So 15 x cos of 53.13... is 9.000000001 feet away.

HELP ME OUT ASAP PLS 20POINTS IF U DO! On Friday, a bowling alley made $842.72 from lane rentals and $412.38 from the concession
ElenaW [278]

Answer:

  $2611.05

Step-by-step explanation:

  earnings = lane rentals + concessions

<u>Friday</u>:

  earnings = $842.72 +412.38 = $1255.10

<u>Saturday</u>:

We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.

  earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95

__

Then the total earnings for both days were ...

  $1255.10 +$1355.95 = $2611.05
