31/50
31 ÷ 50 = 0.62
0.62 x 100 = 62%
So the answer is 62%
Hope this helps I didn't know if the 7k was apart of the problem or a typo

Answer:
a = 9 meters
Step-by-step explanation:
The perimeter is the sum of the side lengths:
28 m = a + 2m + a + 8m
18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms
9 m = a . . . . . . . . . . . . . . . divide by 2
The value of a is 9 meters.
Since each type of drink (lemonade, water, and juice) is equally likely to be chosen, the probability of choosing a type of drink is 1 in 3 picks. Thus, in order to get all three types of drinks, one must pick 3 times.
<em>Answer:</em>
a = 7 & a = −7
<em>Explanation:</em>
Rewrite the equation as
(x+a)(x−a)=x^2−49
Simplify (x+a)(x−a)
x^2−a^2=x^2−49
Move all terms not containing a to the right side of the equation.
−a^2=−49
Multiply each term in −a^2=−49 by −1
a^2=49
Take the square root of both sides of the equation to eliminate the exponent on the left side.
a=±√49
The complete solution is the result of both the positive and negative portions of the solution.
a=7,−7
