Starting from 300 feet away, a car drives toward you. It then passes by you at a speed of 48 feet per second. The distance dd (i

n feet) of the car from you after tt seconds is given by the equation ​d=|300−48t|​d=|300−48t|. At what times is the car 60 feet from you?​

To this problem, the solution is 5 seconds.

In this scenario, you have the initial distance of 300 feet, a car speed of 48 feet per second, and a final distance of 60 feet. You also have the equation for calculating the distance, which should simplify the problem. You're asked to find out when the distance equals 60 feet. Thus, the calculation would be:

distance= 300-48t
60 = 300ft - 48t
48t = 300 - 60 = 240
t = 5

We understand that

The car's distance d (in feet) from you after a time period of t seconds is represented by the equation

d=\left|300-48t\right|

Determine the times t for d=60\ feet

insert the value of d into the equation

60=\left|300-48t\right|

Calculate t

There are two possible outcomes

First Outcome

60=+(300-48t)

60=300-48t

48t=300-60

48t=240

t=240/48

t=5\ sec

Second Outcome

60=-(300-48t)

60=-300+48t

48t=300+60

48t=360

t=360/48

t=7.5\ sec

thus

the solution is

At the instance t=5\ sec and at the instance t=7.5\ sec

Explicación paso a paso:

Para identificar las brocas existen dos aspectos a considerar:

1.- Las fracciones que comparten el mismo denominador aumentan en orden ascendente a medida que los numeradores incrementan, lo que significa que entre

9/16   3/16    7/16     5/16   11/16    el orden sería (de menor a mayor)

3/16     5/16     7/16     9/16     11/16

2.- Fracciones con diferentes denominadores pueden convertirse a un denominador común /16 multiplicando la fracción, por ejemplo

1/4   =  1*4/4*4   =  4/16

Aplicando este método, todas las fracciones se transforman al formato mencionado previamente y se organizan

1/4   = 4/16

3/8  = 6/16

1/2  = 8/16

5/8 =  10/16

1/8  =  2/16

Por lo tanto, hay diez brocas, comenzando con 1/16 hasta la número 12 que es 12/16

Finalmente, el orden sería:

1/16   2/16  3/16  4/16  5/16  6/16  7/16  8/16 9/16 10/16  11/16 12/16

PIT_PIT [12445]

Answer:

Each of the 4 arrangements will produce a rectangle.

Explanation:

Transforming a rectangle through rotation or translation will not alter its rectangular shape. This principle also applies when reflecting it across any axis. Thus, every sequence among the four provided will result in a rectangle.

when Apple sells their iPads they increase the price $50 from what it cost then to actually make the iPads one Apple Store sold
Leona [12618]
Begin by determining the increase in price for the iPads: $50 multiplied by 10 equals $500. Thus, the iPad's price was raised by $500. Next, subtract this total from the original iPad price: $5,000 minus $500 results in $4,500. This indicates that the actual cost for 10 iPads, unadjusted by the increase, stands at $4,500. To find the individual iPad cost, divide that total by 10, leading to $4,500 divided by 10, which gives $450. Therefore, the manufacturing cost of each iPad is $450.

Answer: The least amount spent amounts to £12.92 Step-by-step explanation: Given Number of Cartons = 38 A carton costs 45 pence 4 cartons cost £1.56 In order to minimize expenses, one must opt for the cheaper choice. Since there are 100 pence in £1, this means that £1.36 is equivalent to x pence, where x * 1 = 1.36 * 100, leading to x = 136 pence for four cartons. To find the cost of a single carton, divide x by 4; thus, x/4 = 136p/4, resulting in x/4 = 34 pence. This indicates that a carton of juice can be purchased at 34 pence and 45 pence, with 34 pence being the better deal. Therefore, the total expenditure equals 34 * 38, which converts to 1292p and subsequently to £12.92.
