If a piece of ribbon is 6 and 1 over 4. feet long, how long is it in inches?

timama [110]

The piece of ribbon would be 75 inches. The ribbon would be 75 inches because 1 foot would be 12 inches and you would multiply 12 by 6 to get 72. Then, 1/4 of a foot would be 3 inches because you could divide 12 and 4(the denominator you are dealing with) to get 3. Then, add 72 + 3 to get 75. Hope this helps!

Jamal is running 42 kilometers. The amount of time t it takes Jamal to run varies inversely with the rate, r, at which he runs,

leva [86]

Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r

The position of a passenger train that is traveling at an initial speed of 14 feet per second and continues to accelerate can be

salantis [7]

Solving the system of equations, it is found that a viable time that the trains are side by side is given by:

B. 15 sec

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

$y = 14t^2$

$y = 130t + 1200$

They will be side by side when:

$14t^2 = 130t + 1200$

$14t^2 - 130t - 1200 = 0$

It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:

$\Delta = (-130)^2 - 4(14)(-1200) = 84100$

$x_1 = \frac{130 + \sqrt{84100}}{28} = 15$

$x_2 = \frac{130 - \sqrt{84100}}{28} = -5.71$

Time is a non-negative measure, hence option B is correct.
