Answer:
U just need to guess it does not have to be exact just say like 200 bricks and u will get it right.
Answer:
Step-by-step explanation:
0.005 * x = 0.625 Divide both sides by 0.005
0.005x/0.005 = 0.625/0.005 Do the division
x = 125
So what that means is 0.625 is 125 times larger than 0.005
Answer: Approximately 112.86 miles in any direction away from the radio station
Step-by-step explanation: If the radio signal of the radio station can cover a circular area of 40,000 square miles, it simply means any direction away from the radio station that is within the coverage area. With the radio station as the center, we would have a radius that can reach any point within the area, and any distance beyond the radius would be out of coverage area. If the area has been given as 40000, then we have;
Area of a circle = pi x r^2
40000 = 3.14 x r^2
By cross multiplication we now have
40000/3.14 = r^2
Add the square root sign to both sides of the equation
112.8665 = r
Therefore, the farthest a person can live away from the radio station is approximately 112.86 miles
Answer:
12 = -3 - 3x
Step-by-step explanation:
Same concept as the last question I answered. First, let's derive a formula from the given model. So we have 3 negative x and 3 negative 1 which equal to 12 positive ones, this can be written as:
-3x - 3 = 12
which can be rewritten as
12 = -3 - 3x
