Answer:

geometric sequence

Step-by-step explanation:

A geometric sequence has a common ratio r between consecutive terms.

Here r = [tex]\frac{30}{180}[/tex] = [tex]\frac{5}{30}[/tex] = [tex]\frac{1}{6}[/tex]

Then sequence is geometric

Answer:

give each charity $60

Step-by-step explanation:

$814 to divide equally to 5 charities.

From 814  if we give   -100,  -100, -100, -100, -100, we have left 314 to split in 5

the most useful next step is to give each charity $60

From $814  if we give   -100, -100, -100, -100, -100

                                         -60, -60, -60, -60, -60  

we have left now:

814 -5*100 -5*60 = 814-500-300 = $14 left to split among the 5 charity.

x=2 y=3

Step-by-step explanation:

first multiply equation 2 with (+2)

5x-2y=4

6x+2y=18

now add equation 1 to equation 2

11x=22

x=2 now substitute x=2 in equation 1 or 2

5(2)-2y=4 10-2y=4 -2y=4-10 -2y=-6 y=3

Answer:

$25.80

Step-by-step explanation:

you have to add 16.50 to -42.30

This balance is negative.

================================================================

Explanation:

Start with -42.30 and add on 16.50

-42.30+16.50 = -25.80 is the final balance

The negative balance means Marcos owes this amount of money to the bank. This is true even though he deposited $16.50; he would need to deposit another $25.80 to get out of debt (this is assuming that there aren't any other bank fees coming down the line).

We can think of -42.30+16.50 as 42.30-16.50, but then make the result negative since -42.30 has a larger absolute value compared to 16.50

Answer:

The Energy of an Electron

The energy of an electron is of the same order of magnitude (is in the same range) as the energy of light. The lines in the spectrum of an element represent changes in the energy of electrons within the atoms of that element. By studying these spectra, scientists have drawn various conclusions about the behavior of electrons in atoms.

1. The energy of an electron depends on its location with respect to the nucleus of an atom. The higher the energy of an electron in an atom, the farther is its most probable location from the nucleus. Notice that we say probable location. Because of the electron's small size and high energy, we are limited in how precisely we can mark its position at any instant. We can only describe regions around the atom's nucleus within which the electron may be found.

2. In describing these regions of space, we also recognize that the energy of an electron is quantized. What does this statement mean? A property is quantized if it is available only in multiples of a set amount. If you are pouring a soft drink from a can, you can pour out as much or as little as you like. However, if you are buying a soft drink from a machine, you can buy only a certain amount. You cannot buy a half or a third of a can of soda; you can buy only a whole can or several cans. Soft drinks dispensed by a machine are available only in multiples of a set volume, or quantum. Thus, the dispensing of soft drinks by machine has been quantized.

Energy can also be quantized. If you are climbing a ladder, you can stop only on the rungs; you cannot stop between them. The energy needed to climb the ladder is used in finite amounts to lift your body from one rung to the next. To move upward, you must use enough energy to move your feet to the next higher rung. If the available energy is only enough to move partway up to the next rung, you cannot move at all because you cannot stop between rungs. Thus, in climbing the ladder, your expenditure of energy is quantized.

Step-by-step explanation:

2x-4y=20

y=-3+x/3

2x-4(-3+x/3)=20 ⇒ 2x+12-4x/3=20 ⇒ 2x/3+12=20 ⇒ 2x/3=8

Answer:

1/2 and -1

Step-by-step explanation:

Rise  = 2-1 = 1

corresponding Run = 6 -4 =2

rise/run = 1/2 = slope

So we know that when x=0 we will find the y intercept/

put them in ordered pair you will find

(6,2)

(4,1)

the next one should be (2,0)

and (0,-1)

So the y intercept is -1

Answer:

m=1/2

b=-1

Step-by-step explanation:

to find the slope, we need to see what values x and y increase by. in this table, we can see that as x increases by 2, y increases by 1. since slope is written as rise(x)/run(y), we can write the slope as 1/2.

for the y-intercept, we can use how the x and y values increase as well. we need to find the value of y when x is 0. we know that as x increases by 2, y increases by 1, so we need to do the opposite of both to find the y-intercept. this would be x decreasing by 2 and y decreasing by 1. we can make a table to find the y intercept.

x - 0, 2, 4, 6, 8, 10

y - -1, 0, 1, 2, 3, 4

we can see here that when x=0, y=-1, so that is the y intercept or b value.

-55 is the value of the expression 5m+10(m-1) when the value of m is -3.

The given expression is 5m+10(m−1).

We need to find the value of expression when m is -3.

Let's substitute the value of m=−3 into the expression 5m+10(m−1):

5m+10(m−1)

=5(−3)+10((−3)−1)

=−15+10(−4)

=−15−40

=−55

Hence, the value of the expression is -55.

Answer:

Step-by-step explanation:

Answer:

B = 60

Step-by-step explanation:

A = 36

B = 60

We are told that the LCM of A and be is 180. That would mean that 180/36 = 5

greatest common factor (GCF) of A and B is 12. Multiply this by the GCF of 12 to get 60.

Check to see if this works:

The GCF of 12: 60/12 = 5 and 36/12 = 3: Checks

The LCM of 180: 180/36 = 5; 5*36 = 180 and 3*60 = 1180; Checks

m = (Y2 - Y1)/(X2 - X1)

m = (3 - 1)/(6 - 2)

m = 2/4 <==> ½

Given points,

(2,1) = (x₁, y₁)

(6,3) = (x₂, y₂)

To find the slope, we need to use the formula =》(y₂ - y₁)/(x₂ - x₁)

So,

(y₂ - y₁)/(x₂ - x₁)

= (3 - 1)/(6 - 2) [substitute the values]

= 2/4

= 1/2

◇ Slope of the line = 1/2.

Answer:

True

Step-by-step explanation:

Multiplying a number by 3 will produce the same value as adding 6 to that number can be expressed algebraically as:

3x = x + 6

In order to determine whether the given statement is true, we can solve for x:

Start by subtracting x from both sides:

3x - x = x - x + 6

2x = 6

Divide both sides by 2:

2x/2 = 6/2

x = 3

Substitute the value of x into the original equality statement:

3x = x + 6

3(3) = 3 + 6

9 = 9 (True statement).

Therefore, it is true that when we multiply a number by 3, we get the same value as if we added 6 to that number.

Answer:

k < - 11

Step-by-step explanation:

- 3k - 12 > - k + 10 ( add k to both sides )

- 2k - 12 > 10 ( add 12 to both sides )

- 2k > 22

Divide both sides by - 2 , reversing the symbol as a result of dividing by a negative quantity.

k < - 11

Hi!

----------------------------------------------------------------------------------------------------------------

-3k-12>-k+10

-3k+k>10+12

-2k>22

-k>11

Now, when we divide by a negative variable, we change the sign of our inequality:

k<-11

Answer:

You add all of the numbers of the set and how many numbers there are.

Here is an example:

The set is: {3, 7, 2, 9, 1}

There are five numbers, 3, 7, 2, 9, and 1. We then add all these numbers.

3 + 7 + 2 + 9 + 1 = 22

22 divided by 5 = 22/5 = 4.4

The average number between the set, "{3, 7, 2, 9, 1}" is 4.4.
