Answer:
0.05
Step-by-step explanation:
Given parameters:
The scaled height of the dog house = 6cm
Original height = 51inches
let us convert the original height to cm;
1in = 2.54cm
51in = 51 x 2.54 = 129.54cm
Scale factor;
=
= 0.05
The scale factor is 0.05, the drawing has been reduced by a multiple of 0.05 of the actual height
Answer:
16 seconds (Approximately)
Step-by-step explanation:
Given:
The function that gives the distance of snowboarder from the bottom of hill with time 'x' is:
Final position of the snowboarder is
Now, plugging in 100 for 'd' and solving for 'x', we get:
Adding -1100 both sides, we get:
Dividing both sides by -4, we get:
Taking square root and neglecting the negative root as time can't be negative. So,
Therefore, after 16 seconds, the snowboarder will be at a distance of 100 ft from bottom of hill.
