Answer:

C)  45 ft²

Step-by-step explanation:

<u>Formulae</u>

Area of a square = x²  (where x is the side length)

Area of a triangle = 1/2 × base × height

The surface area of a square pyramid comprises:

  • square base
  • 4 congruent triangles

⇒ area of square base = 5² = 25 ft²

⇒ area of triangular face = 1/2 × 5 × 2 = 5 ft²

⇒ Total surface area = area of square base + 4 triangular areas

                                   = 25 + 4(5)

                                   = 25 + 20

                                   = 45 ft²

Area of base

  • side²
  • 5²
  • 25ft²

Area of one triangle side

  • 1/2(2)(5)=5ft²

Area of 4 sides

  • 5(4)=20ft²

TSA

20+25=45ft²

What is the equation of the line that passes through the point (8,3) and has a slope of 1/4<br> ​
saul85 [17]

Answer:

equation of the line having slope 1/4

that passes through (8,3) is given by

y - 3 = 1/4 ( x - 8)

or, 4y - 12 = x -8

or, 4y -12 - x + 8 = 0

or, 4y - x - 4 = 0 , which is the required equation.

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.

What's the answer to this ? Question
AURORKA [14]
The answer is 10/14

How: 7 is half of 14 so 14 would be the denominator which is the bottom number. So what would 5 be half of? (think of 5+5) It's 10! So 10 would be the numerator which is on the top making the fraction 10/14.
Hope this Helps!
