What is the surface area of the rectangular pyramid shown? 59.5 cm2 63 cm2 75.5 cm2 99 cm2

Answers

Answer 1
Answer:

Answer:

Option D.

Step-by-step explanation:

In this question figure of pyramid is attached below the question .

Surface area of the rectangular pyramid :

Area of the Base = Length × Width

                            = 10 × 2 = 20 cm²

Area of Lateral #1 = (1)/(2)(P)(L)

                             = (1)/(2)(10*6.3)

                             = 31.5 cm²

Area of Lateral #2 = (1)/(2)(8* 2)

                               = (16)/(2)

                               = 8 cm²

Surface area of the pyramid = 20 + 2(31.5) + 2(8)

                                                = 20 + 63 + 16

                                                = 99 cm²

Surface area of the pyramid is 99 cm²

What is the answer to 2/3x + 1 = 5

Answers

Here are the steps. I'll try to make them as easy as possible :)

2/3x+1=5

Step 1: Subtract 1 from both sides.
2/x+1-1=5-1

Step 2: Multiply both sides from 3/2

(3/2)*(2/3x)=(3/2)*(4) 

And the answer will be 6
x=6


Let's solve the equation step-by-step

In the last question I've answered for you, I've said it can be a little bit easier to work out a math problem with first rewriting it. So, let's do that --

2/3x + 1 = 5

Step 1) Subtract 1 from both sides

2/3x + 1 - 1 = 5 - 1

2/3x = 4

Step 2) Multiply both sides by 3/2

(3/2) × (2/3x) = (3/2) × (4)

x = 6

FINAL ANSWER -

x = 6

What is the definition of variable expression

Answers

In mathematics, a variable expression is an expression that contains operations, numbers, and variables.

For example, if I have 6 coins in my pocket in . addition to the number of coins that are in my jar at home, then then the total number of coins would be represented as X + 6.

X would represent the unknown amount of coins in my jar at home.

This would be a variable expression because it contains an operation "addition", a number "4", and a variable "X."
basically variable is a term that specifies unspecified numbers..
variable expression:
                           it is the algebraic expression in which both numbers and variables are comprised by means of arithmetic operations 
example:
1) 2a + 3
2) 5/2 - x
