The keypad on Sam’s cell phone is shown at right. As you can see,
anzhelika [568]

To complete the table we must carefully observe the keypad, we will notice that each number is equivalent to 3 letters of the alphabet except the numbers 7 and 9 which have 4 letters each.

<h3>How does the keypad work?</h3>

Previously, cell phone keypad had a different layout than today. The numbers were related to the letters of the alphabet and the number key was pressed according to the letters that were related.

For example, if you wanted to type the letter B, you would have to press the number 2 key twice.

The relationship of numbers and letters was distributed as follows:

  1. It had no letters.
  2. A, B and C.
  3. D, E and F.
  4. G, H and I.
  5. J, K and L.
  6. M, N and O.
  7. P, Q, R and S.
  8. T, U and V.
  9. W, X, Y, and Z.

According to the above, the table would be completed as follows.

Note: This question is incomplete because there is some missing information. Here is the missing information:

1. Complete this table to show the relation from letter to number.

All pictures are below please help Sandi had the following problem on her math test: . She showed her work on the test as follow
Semmy [17]

Answer/Step-by-step explanation:

The basic rule of maths operation used by Sandi, is the PEMDAS Rule.

Maths operations like the one Sandi was given must follow this rule. According to the rule:

P - Parentheses, solve everything you have in the parentheses first.

E - Exponents, do the exponents.

M - Multiplication or

D - Division operation should come next.

A - Addition or

S - Subtraction comes last.

Let's apply this rule to see if Sandi rightly applied the PEMDAS Rule:

Step 1:

6*4 + 2 ÷ 2 - 7 (given)

Step 2: perform operation involving Multiplication first according to PEMDAS Rule.

24 + 2 ÷ 2 - 7 (multiplication first. I.e. 6*4 = 24)

Step 3: perform division operation next.

24 + 1 - 7 (division operation. i.e. 2÷2 = 1)

Step 4: Subtraction

24 - 6 (i.e. +1 - 7 = -6) this is where Sandi made an error.

Step 5: subtraction

24 - 6 = 18.

Sandi made a mistake in step 4 and 5. Her addition and subtraction operation was wrong. 1 - 7 = -6 not +6.

During operation like this, either subtraction or addition can come first.
