Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x

bulgar [2K]

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

$\frac{y}{x}$ = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

$\frac{t}{p}=1.08$

C. Equation: $x=\frac{m}{4}$

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

$\frac{m}{x}=4$

D. Equation: $V=12s^{2}$

This equation is NOT proportional because side length is squared, so it is not constant linearly.

A rock outcrop was found to have 95.82% of its parent U- 238 isotope remaining. Approximate the age of the outcrop. The half-lif

mixer [17]

Answer:

A) 277 million years

Step-by-step explanation:

Here, decay of U-238 is first order reaction. (since most of the nuclear decays are first order).

so, the equation t = $\frac{1}{k}$ × ln( $\frac{A(0)}{A}$ )

where, t = time from start of reaction

k = reaction constant

A(0) = initial concentration; A = present concentration.

⇒ 4.5 billion = 4500 million years = $\frac{1}{k}$ × ln2.

Now, given 95.82% of parent U-238 isotope is left.

⇒ t = $\frac{1}{k}$ × ln( $\frac{A(0)}{A}$ )

t = $\frac{4500}{ln2}$ × ln( $\frac{100}{95.82}$ )

⇒ t ≅ 277 million years.
