Answer:
8 inches
Step-by-step explanation:
Surface area of a prism is:
S = 2A + Ph
where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.
The base is a square, so A = s² and P = 4s:
S = 2s² + 4sh
Given that S = 512 and h = 12:
512 = 2s² + 4s(12)
512 = 2s² + 48s
256 = s² + 24s
0 = s² + 24s - 256
0 = (s + 32) (s - 8)
s = -32, s = 8
Since s must be positive, s = 8 inches.
Answer: Treats are an essential part of positive reinforcement, rewards-based training, but you also need to be mindful to balance your dog’s treats with their overall daily calories. Give them too many treats and you won’t just spoil their appetite for actual meals, but you could also make your dog overweight and unhealthy.
Step-by-step explanation:
Given the diameter of a circle, we can find its radius by dividing the diameter by 2, like this:
Where r is the radius and d is the diameter of the circle, by replacing 30 for d, we get:
Then, the radius of this circle equals 15 m
Answer:
70 and 110 degrees
Step-by-step explanation:
7+11=18 units
180 degrees/18 units=10 degrees per unit
7x10=70 degrees
11x10=110 degrees
