0.0181 yd/s. To solve this problem you use dimensional analysis. You convert the feet and minutes to yards and seconds by using this process. The units of feet and minutes cancel out, so you are left with yards per second. You should get 0.0180555555 when you multiply and divide everything, but you can just round it to 0.0181 or whatever place your teacher wants.

What is 16 divided by X^2 equals 8 divided by X + 6?

zaharov [31]

Solve: $\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\frac{16}{x^{2}} = \frac{8}{x + 6}$

$\text{Cross multiply: } 16(x + 6) = 8x^{2}$
$\text{Simplify: } 2(x + 6) = x^{2}$
$\text{Expand: } 2x + 12 = x^{2}$

$\text{Solve for x: } x^{2} - 2x - 12 = 0$

$\text{Use the quadratic equation: } x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$
$x = \frac{2 \pm \sqrt{4 + 48}}{2}$
$x = \frac{2 \pm \sqrt{52}}{2}$
$x = \frac{2 \pm \sqrt{13 \cdot 4}}{2}$

$x = \frac{2 \pm 2\sqrt{13}}{2}$
$\therefore x = 1 \pm \sqrt{13}$

Kiron earns $6 more than 3 times what her mother earned at her age working. If

svet-max [94.6K]

Answer: Kiron's mother earned 4 dollars an hour when she was Kiron's age.

Step-by-step explanation: Let k be Kiron's pay and m be her mother's pay.

From this, we can derive the equation k=3m+6, and since we know k=18 we get

3m+6=18

3m=12

m=4
