Answer:

Step-by-step explanation:

$\bold{METHOD\ 1:}\\\\\begin{array}{ccc}126\ mi&-&3h\\\\x\ mi&-&4h\end{array}\qquad\text{cross multiply}\\\\3x=(126)(4)\\3x=504\qquad\text{divide both sides by 3}\\x=168\ mi$

$\bold{METHOD\ 2:}\\\\126\ mi\ \text{in}\ 3\ h,\ \text{then}\ \dfrac{126\ mi}{3}=42\ mi\ \text{in}\ 1\ h.\\\\\text{If}\ 42\ mi\ \text{in}\ 1\ h,\ \text{then}\ (42\ mi)(4)=168\ mi\ \text{in}\ 4h.$

Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 4

Height h = 21

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$

Rearrange the quadratic equation so that it is equal to 0 then factor the equation x^2-4x=-2x+24

irinina [24]

X^2-4x=-2x+24
x^2-2x=24
x^2-2x-24=0

(x-6)(x+4)

Proof:
-6+4=-2
-6*4=-24

Final answer: (x-6)(x+4)

Sams scooter charges $30 +$8per hour rosie's charges $20 fee +$10 per hour

DerKrebs [107]

The base fee ($30 & $20) are the independent variables.

An independent variable is a variable that does not depend on others

$8 & $10 depend on the number of hours so that is not the independent variable
