The solution is 700 feet, as dividing 5,280 feet by 1 mile results in 88 feet per second. By then multiplying 88 feet by 8 seconds, the result is 704 feet. Since the phrasing of the question included "about," I interpreted that to imply rounding. Thus, 704 is rounded down to 700, leading to this conclusion.

The result is 704 feet

Detailed explanation: the car travels at a rate of V= 60 miles per hour

Initially, convert the speed from miles per hour to feet per second.

V=\frac{60\times 5280}{60\times 60} \frac{ft}{s} = 88 \frac{ft}{s}

Next, to find the tunnel's length, L= speed of car multiplied by the time taken

Thus, L=88\times 8 feet=704 feet

Inessa [12570]
To resolve this issue, you simply multiply base 1 by height 1, which equals base 2 multiplied by height 2. Inserting our values yields 24 * 4 = 5 * height 2. By solving, we find the missing height to be 19.2.

Respuesta: Los contratos de opciones pueden ser valuados empleando modelos matemáticos tales como el modelo de precios Black-Scholes o el modelo Binomial. El costo de una opción se divide principalmente en dos componentes: su valor intrínseco y su valor temporal.... El valor temporal depende de la volatilidad anticipada del activo subyacente y del tiempo restante hasta que la opción expire.

Explicación paso a paso: ¡espero que esto ayude!

In 1988, a certain model of car cost $17000. What would be the cost of that car in 2017 dollars?
Zina [12379]
$66,092.50 Step-by-step explanation: The car price was $17,000 back in 1988. The annual rate of inflation from 1988 to 2017 was 3.54%. After factoring in inflation, $17,000.00 from 1988 is equivalent to $66,092.50 in 2017. Thus, the approximate cost of that vehicle in 2017 would be $66,092.50.
