Answer:
x = ± 
Step-by-step explanation:
Given
mx² = p ( divide both sides by m )
x² = 
( take the square root of both sides )
x = ±
Answer:
4 mph
Step-by-step explanation:
Travel time is proportional to distance and inversely proportional to speed. If c represents the speed of the current in miles per hour, an equation for the total trip time is ...
825/(29 -c) +825/(29 +c) = 58 . . . . . . hours travel time
825(29 +c) +825(29 -c) = 58(29 -c)(29 +c)
58c² -928 = 0 . . . . . . . rearrange to standard form
58(c -4)(c +4) = 0 . . . . factor
Values of c that satisfy this equation are 4 and -4. For the purpose here, we'll choose the positive solution.
The speed of the current is 4 miles per hour.
Answer:
The answer is C on Edge or "The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4."

Answer:
In a sporting event, the scoring area (shown here) consists of four concentric circles on the ice with radii of 6 inches, 4 feet, 6 feet, and 7 feet. If a team member lands a (43-pound) stone randomly within the scoring area, find the probability that it ends up centered on the given color. (a) red (b) white (c) blue (a) The probability that it ends up centered on red is (Type an integer or a simplified fraction.) (b) The probability that it ends up centered on white is (Type an integer or a simplified fraction.) (c) The probability that it ends up centered on blue is (Type an integer or a simplified fraction.) of the answer boxes
The number of a radius is half of the diameter. so 3 is half of 6. your diameter is 6.
