A converse is when we switch the hypothesis and conclusion, so "if a figure is a square then it has four right angles" the converse would be "If a figure has four right angles then it is a square" Which is false because of rectangles, your answer is D.

The function A = A 0 e -0.0077x models the amount in pounds of a particular radioactive material stored in a concrete vault, whe

AysviL [449]

Answer:

After 80 years 432 pounds of radioactive element will be remaining.

Step-by-step explanation:

A function $A_{t}=A_{0}e^{-0.0077x}$ models the amount of a radioactive material.

Here x = number of years taken for decay.

If $A_{t}=432$ pound and $A_{0}=800$ pound, then we have to calculate the time for decay.

$A_{t}=A_{0}e^{-0.0077x}$

$432=800e^{-0.0077x}$

$e^{-0.0077x}=\frac{432}{800}$

Take log on both the sides of the equation

$ln(e^{-0.0077x})=ln(\frac{432}{800} )$

-0.0077x = ln(0.54)

-0.0077x = -0.616186

x = $\frac{0.616186}{0.0077}$

x = 80.02 years

Therefore, After 80 years 432 pounds of radioactive element will be remaining.

Andrew has a rewards card for a movie for a a movie theater.

Alinara [238K]

Free movie, F = 87pts

Initial reward, I = 10pts

Additional reward, A = 7pts

Movie visit, X

F = I + XA

87 = 10 + 7X

X = (87-10)/7

X = 11

After 11 movie visits Andrew will have enough points for a free movie.

sineoko [7]

Answer:

x=18

Step-by-step explanation:

S=(n-2)180

S=(5-2)180

S=3x180

S=540

540=(9x-6)+(3x+23)+95+((7x-4)+90

540=19x+198

540-198=19x

342=19x

342/19=x

x=18
