Pretty certain it’s 416.25 meters
I used the speed formula
Speed = distance travelled / time interval
Then I isolated the distance by multiplying time interval on both sides of the equation
92.5 m/s = X
—- (4.5s) to isolate X
4.5 s
(4.5 s) 92.5 m
— (the seconds will cancel out) = 416.25 meters

Answer: the pair of sunglasses
Explanation:
A good pair of sunglasses are composed of abosorbent lenses that filter the sunlight that affects the eyes retina, especially ultraviolet (UV). So, these sunglasses are used to reduce the amount of light or radiant energy transmitted.
On the other hand, normal reading glasses (in which the lens glass has not been treated to filter ultraviolet sunlight) will let UV rays pass through.
Therefore, if both glasses are exposed to sunlight, the sunglasses are expected to be warmer by absorbing that radiant energy and preventing it from reaching the eyes.
You have to draw a mathematical spatial axes .in order to judge is it right or not .. well you have to draw the crest and trough both of 1 cm in length and the total wavelength (same phase on the wave of 2 cm ) something like this
Answer:
Monthly cost = 35.7
Explanation:
Given the following data;
Power = 7000 Watts
Time = 10 minutes
Number of days = 30 days
Conversion:
60 minutes = 1 hour
10 minutes = 10/60 = 0.17 hours
To find the monthly cost of electricity;
Energy = power * time
Energy consumption = 7000 * 0.17
Energy consumption = 1190 Watt-hour = 1.19 KWh (1 Kilowatts is equal to 1000 watts).
Next, to find cost of monthly energy consumption;
Cost = 1.19 * 30
Cost = 35.7
