Answer:

11.68

Step-by-step explanation:

23.76 + 1.49= 25.25

25.25 + 2.57= -27.82

39.50

27.82

11.68

Its important to remember that 23.76, 1.49, and 2.57 are all negative numbers that you have to add up and subtract it from $39.50 to get how much Isabella made.

Part 1 - Application

madam [21]

Answer:

see explanation. (I did this exact assignment this morning, and this is very similar to what I submitted)

Step-by-step explanation:

The contrapositive of a conditional is the same as the converse of the inverse of the conditional.

The best way to prove/support this statement is to create an example. You should start by creating a conditional; you can then form the conditional's converse, inverse, and contrapositive. Here is an example:

Conditional: If C, then D. (starting statement)

Converse: If D, then C. (conditional reversed)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

Based on the information from the example you gave, you can conclude:

The converse of the inverse: If not D, then not C. (reversed opposite of the conditional)

Because: The converse is the conditional reversed (If D, then C). The inverse of the converse, in this case, would then make it the opposite (If not D, then not C).

I have not yet received a grade on this assignment, but I know the information is correct; the amount of explanation you need to give really depends on how your teacher grades. Personally, I just submitted an example (similar to the one above) that was color-coded to help show the different parts of each statement.

I hope this helps! :)

You have 8,640 grams of a radioactive kind of cesium. If its half-life is 30 years, how much

Vikki [24]

The mass of cesium left afer 120 years if the original mass of cesium is 8640 with an half-life of 30 years, is 540 grams.

This can be defined as the time taken for half the amount of a radioactive substance to decay.

To calculate the amount of cesium left after 120 years, we use the formua below.

Formula:

R' = R/( $2^{T/t}$ )............. Equation 1

Where:

R = Original amount of Cesium
R' = New amount of cesium
T = Total time
t = Half-life

From the question,

Given:

R = 8640
T = 120 years
t = 30 years

Substitute these values into equation 1

R' = 8640/( $2^{120/30}$ )
R' = 8640/ $2^{4}$
R' = 8640/16
R' = 540 grams.

Hence, The mass of cesium left afer 120 years is 540 grams.
