Answer:

#1-

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

Answers

Answer:

A B C F

Step-by-step explanation:

Based on this exercise, the true inequalities are:

0 < √8 ≡ 0 < 2.8284.√8 < 3 ≡ 2.8284 < 3.√8 > √7 ≡ 2.8284 > 2.6458.1 < √8 ≡ 1 < 2.8284.

What is an inequality?

An inequality is a mathematical relation that can be used to compare two (2) or more integers in an equation based on any of the following:

Less than (<).Greater than (>).Less than or equal to (≤).Greater than or equal to (≥).

In order to determine the true inequalities, we would evaluate each of the inequalities as follows:

0 < √8 ≡ 0 < 2.8284 (True).√8 < 3 ≡ 2.8284 < 3 (True).√8 > √7 ≡ 2.8284 > 2.6458 (True).√8 < 2 ≠ 2.8284 > 2 (False).√8 > 8 ≠ 2.8284 > 8 (False).1 < √8 ≡ 1 < 2.8284 (True).

Answers

Answer:

54j + 72 + 9j and 63j + 72

Step-by-step explanation:

I just simplified it

So 9(6j + 8 + 1j) can be distributed to (9)(6j) + (9)(8) + (9)(1j) which equals 54j + 72 + 9j because 9*6j = 54 , 9*8 = 72 , and 9*1j = 9j

54j + 72 + 9j can also equal 63j + 72 because 54j + 9j = 63j

Brad paid for a book that cost $13.40 with a $20 bill. What is the least combination of coins and bills that can be used to make his change? What are two other different combinations of coins and bills that can be used to make the change?

Answers

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

can someone answer these questions please, i'm having trouble with them
See them in the picture attached.

Answers

Answer:

1. $686.94

2. $735.03

3. $10707.55

4. $17631.94

5. $19635.72

Step-by-step explanation:

1st Question:

The interest rate is 7% for each year. This means that each year the person has to pay 7% more than the previous amount. So we need to multiply the initial amount by (0.07+1=1.07) in order to get the interest for the first year. if we want to find the second year's interests then we will have to multiply 2 (1.07)'s and so on.

in this case our function is: 600*(1.07)^t=P(t)

when t=2 P(2)=600*(1.07)^2=$686.94

2nd Question:

Function: 600*(1.07)^t=P(t)

when t=3 P(3)=600*(1.07)^3=$735.03

3rd Question:

initial value=$8500

1+0.08=1.08

Function: 8500*(1.08)^t=P(t)

t=3

P(3)=8500*(1.08)^3=$10707.55

4th Question:

initial value=$12000

1+1.08=1.08

t=5

Function: P(t)=12000*(1.08)^t

P(5)=12000*(1.08)^5=$17631.94

5th Question:

Function: 14000*(1.07)^t=P(t)

P(5)=14000*(1.07)^5

P(5)=$19635.72
