25 + 0.25x=45

0.25x=20

x= 20/0.25 = 80

so 80 pounds of trash

1. The answer is $24
32x0.25= 8 32-8=24
2. The answer is $105
150x0.30=45 150-45=105
3. The answer is $52
80x0.35=28 80-28= 105
4. The answer is $59.25
14+25+40=79 79x0.25=19.75 79-19.75=59.25

Answer:

207.24 inches

Hope this helps

Step-by-step explanation:

first you need to find the circumference...

2pi R (r=radius=11)

2 x 3.14 x 11 = 69.08 (i'm using 3.14 as pi so yea...)

3 rotations...

69.08 x 3= 207.24 inches

Answer:

(a). 2399.23 meters.

(b). 1944.19 meters apart.

Step-by-step explanation:

Please find the attachment.

We have been given that standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees.

(a) We are asked to find how far from the shore is the ship.

We know that tangent relates opposite side of a right triangle with its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(9^{\circ})=\frac{380}{x}$

$x=\frac{380}{\text{tan}(9^{\circ})}$

$x=\frac{380}{0.158384440325}=2399.22557$

Therefore, the ship is approximately 2399.23 meters away from the shore.

$\text{tan}(5^{\circ})=\frac{380}{x+y}$

$x+y=\frac{380}{\text{tan}(5^{\circ})}$

$x+y=\frac{380}{0.087488663526}$

$2399.22557+y=4343.419875$

$y=4343.419875-2399.22557$

$y=1944.194305\approx 1944.19$

Therefore, the both ships are approximately 1944.19 meters apart.
