Please let me know the correct answer.

Set h to 640 and solve for t:

640 = -490t^2 + 1120t

Subtract 640 from both sides:

-490t^2 + 1120t - 640 = 0

The formula to solve a quadratic equation is:

x = -b -/+ sqrtroot (b^2-4ac)/(2a) where a = -490, b = 1120 and c = -640

Solve:

x = -1120 -/+ sqrtroot (1120^2-4(-490)(-640) )/ 2(-490)

x = 8/7 = 1.1428 = 1.14

The equation p= 2.5m + 35 represents the price p of a bracelet, where m is the cost of the materials. The price of a bracelet is
Klio2033 [76]
P= 2.5m + 35    (replace p with 115)
115= 2.5m + 35  (subract 35 from each side)
115 - 35 = 2.5m
80 = 2.5m    (divide 2.5 from each side)
80/2.5= 2.5m/2.5
32 = m

The price of the materials is $32

Step-by-step explanation:

Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.
