Remark

An anion is a charged ion that has taken on electrons. So you are talking about an activity that definitely involves electrons. It would seem reasonable to believe that the increase in the size of an ionic radius is caused by an increase in the number of electrons in the valence (outside) ring. The statement is true.

Which size container of cold farm ice cream is the better deal for Sheldon? Explain.
Art [367]

<u>Cold Farms: </u>

<u>Small box </u>

1 pint = $2.50

1 quart = $4.50

<u>Large Box</u>

1 quart = 2 pints .

2 pints  = $4.50

1 pint = $4.50 / 2 = $2.25

<u>Cone Dreams:</u>

<u>Small box </u>

1 quart = $4.25 and

1 pint = $4.25/2 =  $ 2.125

<u>Large Box</u>

1 gallon = $9.50.

1 gallon = 8 pints

8 pints = $9.50.

1 pint = $9.50 / 8 = $ 1.1875.


<h3>15) Therefore, large size container of Cold Farms ice cream is better deal for Sheldon because it cost $2.25 per pint of ice cream as compared to small box cost $2.50 per pint.</h3><h3 /><h3>16) Cone Dreams Large size container cost just $ 1.1875 per pint of ice cream.

What is the missing length.
nasty-shy [4]

Answer:

KS = 12

Step-by-step explanation:

Given that ∆KLM ~ ∆RSK, \frac{KL}{KR} = \frac{KM}{KS} (similarity theorem)

KL = 65

KR = 65 - 52 = 13

KM = 60

KS = ?

\frac{65}{13} = \frac{60}{KS}

Cross multiply

65*KS = 60*13

65*KS = 780

\frac{65*KS}{65} = \frac{780}{65}

KS = 12

Can anybody please help me out with this question I would really appreciate it so much. Please and thank you .
PolarNik [594]

(7x+2)° = (9x–8)°

=>7x –9x = –8–2

=> –2x = –10

=> x = 10/2

=> x = 5

<ADB = (7x+2)°

= 7×5+2

= 37°

<BDC = (9x–8)°

= 9×5–8

= 45 –8

= 37°

<ADC = 37° + 37°

= 74°
