Crime scene investigators are unsure what floor of the building the shot came from. The first floor of the hotel is 25 ft. high. Each subsequent floor is 15 ft. tall. Entry point on car window above horizontal = 12 in. Distance from car window to victim = 42 in. Distance from building to victim’s car = 350 ft. Using the measurements from the scene, determine what floor of the building the shooter came from. Tips: Convert units to feet, Complete ratio to find the height of the shooter in feet. To determine the floor number from feet: 25 + 15x, The floor number = add one to x. Which means the shooter was on which floor? a 5 b 6 c 7 d 8

Answer: 6 floors

Step-by-step explanation: Given that:

The first floor height = 25ft

Where each subsequent floor is 15 ft. tall.

Entry point on car window above horizontal = 12 in.

Distance from car window to victim = 42 in.

Distance from building to victim’s car = 350 ft.

Using similarity in angle method, we have

(25 + 15x)/350 = 12 in/42 in

Convert inches to feet by dividing the value by 12

(25 + 15x)/350 = 1/3.5

Cross multiply

3.5(25 + 15x) = 350

87.5 + 52.5x = 350

52.5x = 350 - 87.5

52.5x = 262.5

X = 262.5/52.5

X = 5

Therefore,

The floor number = 1 + 5 = 6 floors

Can someone help me with this geometry question ASAP ty
Sophie [7]

Answer:

angle S    100  option C

Step-by-step explanation:

P and S are consecutive angles

Interior angles of a parallelogram

1. Opposite angles are congruent

2. Consecutive angles are supplementary (They add to 180 )

(2x+20) + (3x+10) = 180

5x+30 = 180

5x = 150

x= 30

angle S      3x30 +10 =

                   90 +10 =   100

The other angle P      2x30 +20 = 60 +20 = 80

  100 +80 = 180

Because of a problem in the program, the timer in a video player did not begin counting until the video had been playing for sev
Bess [88]

Answer:

105 frames

Step-by-step explanation:

Given that 25 frames are played per second

25 frames= 1 sec

The video already played 3 and 2/5 seconds before the player started to count 0

Write 3 and 2/5 seconds as an improper fraction

=(5*3)+2 / 5 = 17/5 seconds

Multiply by 25 frames

17/5 *25 =85 frames

So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames.Thus,to get the number of frames that were already in count you subtract 85 frames from the 190 frames.

190-85=105 frames.
