H represents the height of the ball at a given time, symbolised as t.
Thus, we just need to find when h = 0 so that we find when it hits the ground.
0 = -4.9t² + 19.6t + 58.8
0 = 4.9t² - 19.6t - 58.8
0 = 49t² - 196t - 588
0 = t² - 4t - 12
0 = (t - 6)(t + 2)
So, t = 6 or -2, but t ≠ -2, since time cannot be negative in this instance.
Hence, at 6 seconds, the ball will strike the ground.
No, just because the phones produced Increases it doesn’t mean that the work rate will get up to 100%. There can always be more workers.
Answer:
The value of x is 10
Step-by-step explanation:
We can use a system of equations to solve this.
Cups of 25% bleach solution used = x
Cups of 1-% bleach solution used = 5
Cups of solution we get = y
The first equation becomes:
x + 5 = y
Using the decimal forms of each percentage solution
25% solution for x cups = 0.25x
10% solution for 5 cups = 0.1(5)
20% solution for y cups = 0.2 y
The second equation becomes:
0.25x + 0.1(5) = 0.2y
So the system of equations is:
x + 5 = y
0.25x + 0.1(5) = 0.2y
Solve both equations simultaneously to find the values of x and y:
x = 10 cups
y = 15 cups

Answer:
Total of Amala’s liabilities is $5500 .
Step-by-step explanation:
Liabilities is defined as the sums of money which it owes .
As given
Amala listed her assets and liabilities. Credit Card Balance Car (Paid in full) Jewelry Student Loan Savings Account Stocks $850 $2,200 $125 $2,500 $1,200 $1,500 .
As Credit card balance , car (Paid in full) and student loan are Amala liabilities .
Thus
Total amount of Amala’s liabilities = Credit card balance + car + student loan .
Putting all the values in the above
Total amount of Amala’s liabilities = 850 + 2200 + 2500
= $5500
Therefore the total of Amala’s liabilities is $5500 .
