GrogVix [38]
Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.

viva [34]
<h2>Answer:</h2><h2>If she  continues to throw darts 75 more times, she could predict to hit the </h2><h2>bull's-eye 15 times.</h2>

Step-by-step explanation:

Shay found that she hit the bull's-eye when throwing darts \frac{2}{10} times = \frac{1}{5}.

In five times, she will hit the dart once.

If she  continues to throw darts 75 more times,

the probability that she will hit the bull's eye =  \frac{1}{5} (75) = 15 times.

If she  continues to throw darts 75 more times, she could predict to hit the

bull's-eye 15 times.

Solve the following problem and show the work. (x - 6)^2 + (y + 1)^2 = 40
Taya2010 [7]

Answer:

see explanation

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form

centre = (6, - 1) and r = \sqrt{40} = 2\sqrt{10}
