If an average car is about 16 feet long, about how many car lengths should you have between you and that car in front of you if

Elden [556K]

Answer: 9 cars.

Step-by-step explanation:

given data:

average length of a car = 16feet

speed of the driver = 100miles/hr

Solution:

First we would need to convert the Speed of the car from miles/hr to Feet/secs.

To do this we know that 1mile/hr = 1.467 feet/secs

= 100m/hr * 1.467

= 146.7Feet/secs.

So now the number of cars between him would be

= 146.7Feet/secs / 16

= 9.17

approximately there should be 9 cars between you.

Slove the simoltanous equation by using substitution or elimination method 5x-3y=1 3x+2y=1<br>

xxTIMURxx [149]

<u>By substitution method </u>

5x - 3y =1

3x + 2y = 1

_____o____o____

$5x - 3y = 1 \\ 5x = 1 + 3y \\ x = \frac{1 + 3y}{5}$

______o____o_____

$3x + 2y = 1 \\ 3( \frac{1 + 3y}{5} ) + 2y = 1 \\ \frac{3 + 9y}{5} + 2y = 1 \\ \frac{3 +9y + 10y}{5} = 1 \\ \frac{3 + 19y}{5} = 1 \\ 3 + 19y = (1)(5) \\ 3 + 19y = 5 \\ 19y = 5 - 3 \\ 19y = 2 \\ y = \frac{2}{19}$

______o_____o____

$x = \frac{1 + 3y}{5} = \frac{1 + 3 \frac{2}{19} }{5} \\ x = \frac{1 + \frac{6}{19} }{5} = \frac{ \frac{19 + 6}{19} }{5} = \frac{ \frac{25}{19} }{5} \\ x = \frac{25}{19} \div 5 \\ x = \frac{25}{19} \times \frac{1}{5} \\ x = \frac{5}{19}$

Subtract c^2 from a^2+b^2, on the left.

Next, enclose your result inside parentheses.

Next, place a " - " sign in front of this last expression.

This result is the value of 2abcos C.
