Engineering notation of the number (8.2 × 103) × (5.0 × 104) is
4.39192 × 10⁵
OR
4.4 ₓ 10⁵.
<h3>What is engineering notation ?</h3>
Engineering notation is same as scientific notation.
According to the given question
Converting (8.2 × 103) × (5.0 × 104) to engineering notation can be done using a base and raising it to the power of 10.
Base can be greater than or equal to 1 and less than 10.
Suppose base is a
∴ 1≤a<10 and the number in engineering notation will be of the form a×10ⁿ
Given (8.2 × 103) × (5.0 × 104) which is
= 844.6 × 520
= 439192
=4.39192 × 10⁵
= 4.4 ₓ 10⁵.

Answer:
7
Step-by-step explanation:
mean means average
there are 8 numbers
add them all up
7+8+9+2+4+5+12+9=56
divide 56 by 8 = 7
Answer:
57.3
Step-by-step explanation:
just rounded up one
Answer:
x=8
A = 192
Step-by-step explanation:
The perimeter is the sum of the outer lengths
17.9 + 22.6 + 3x = 64.5
Combine like terms
40.5 +3x = 64.5
Subtract 40.5 from each side
40.5 +3x -40.5 = 64.5 - 40.5
3x =24
Divide each side by 3
3x/3 = 24/3
x = 8
The area of a triangle is given by
A = 1/2 bh
The base is 3x = 3(8) =24
and the height is 2x = 2(8) =16
A = 1/2 (24) * 16
A =192
