Answer:

A) 48

B) 3 seconds

Step-by-step explanation:

A) -16+40+24 = 48

B) -16t² + 40t + 24 = 0

2t² - 5t - 3 = 0 (÷ by -8)

2t² - 6t + t - 3 = 0

2t(t -3) + 1(t - 3) = 0

(t - 3)(2t + 1) = 0

t = 3, t = -½

In the parking lot there are 1960 convertibles and 490 minivans, for a total of 2450 cars all together what is the ratio of cars
Sidana [21]

Answer: 5:4

Step-by-step explanation:

Given : The number of convertibles  = 1960

The number of minivans = 490

Total cars =  2450

The ratio of A to B can also be written as \dfrac{A}{B}.

The ratio of cars to convertibles = \dfrac{\text{Number of cars}}{\text{Number of convertibles}}

=\dfrac{2450}{1960}\\\\=\dfrac{5}{4}\ \ \ \text{[Simplest form]}

Hence, the  ratio of cars to convertibles = 5:4
