Please solve this -10+1/3y>2/3

Marianna [84]

Solving $-10+\frac{1}{3}y>\frac{2}{3}$ we get $y>32$

Step-by-step explanation:

We need to solve the expression:

$-10+\frac{1}{3}y>\frac{2}{3}$

Solving the expression

Adding 10 on both sides:

$-10+\frac{1}{3}y>\frac{2}{3}\\=-10+\frac{1}{3}y+10>\frac{2}{3}+10\\=\frac{1}{3}y>\frac{2+30}{3}\\=\frac{1}{3}y>\frac{32}{3}\\$

Multiplying 3 on both sides

$=\frac{1}{3}y\times3>\frac{32}{3}\times3\\=y>32$

So, Solving $-10+\frac{1}{3}y>\frac{2}{3}$ we get $y>32$

a person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 secon

larisa [96]

Answer:

20 feet

Step-by-step explanation:

$\frac{80 feet}{40 seconds}$ = $\frac{x feet}{10 seconds}$

Simplify $\frac{80}{40}$

$\frac{80}{40}$ = $\frac{2}{1}$

Every 1 second, a person will walk 2 feet.

$\frac{x}{10}$ = $\frac{20}{10}$

X = 20 feet

A farmer in China discovers a mammal hide that contains 37% of its original amount of C-14. Find the age of the mammal hide to t

Naya [18.7K]

Answer: 54678 years

Step-by-step explanation:

This can be solved by the following equation:

$N_{t}=N_{o}e^{-\lambda t}$ (1)

Where:

$N_{t}=54\%=0.54$ is the quantity of atoms of carbon-14 left after time $t$

$N_{o}=1$ is the initial quantity of atoms of C-14 in the mammal hide

$\lambda$ is the rate constant for carbon-14 radioactive decay

$t$ is the time elapsed

On the other hand, $\lambda$ has a relation with the half life $h$ of the C-14, which is $5730 years$ :

$\lambda=\frac{ln(2)}{h}=\frac{ln(2)}{5730 years}=1.21(10)^{-4} years^{-1}=0.000121 years^{-1}$ (2)

Substituting (2) in (1):

$0.54=1e^{-(0.000121 years^{-1}) t}$ (3)

Applying natural logarithm on both sides of the equation:

$ln(0.54)=ln(1e^{-(0.000121 years^{-1}) t})$ (4)

$-0.616=-(0.000121 years^{-1}) t$ (5)

Isolating $t$ :

$t=\frac{-0.616}{-0.000121 years^{-1}}$ (6)

$t=54677.68 years \approx 54678 years$ (7) This is the age of the mammal hide

Hi
You can choose to points (x,y) which solve the equation, like (0,-3) and (4,0) and then draw a line through the points.
