- <em>combined mass in scientific notation can be written as</em> 97.2× kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg

The lateral area of the tea bag is the sum of the areas of the four triangles.
LA = 4 x (1/2)bh
Substituting,
LA = 4 x (1/2)(4 cm)(5 cm) = 40 cm²
The surface area is the sum of the lateral area and the area of the base.
SA = LA + BA
SA = 40 cm² + (4 cm)(4 cm) = 56 cm²
The answer would be 249 with a remainder of 1
You would first put the 2 over the 4, as 2 times 2 is 4. Bring the 9 down. 2 goes into 9 about 4 times, but it has the remainder of 1. You bring the other 9 down, and now it says 19. 2 x 9 equals 18, so you put the 9 on top and there you have 249 with the remainder of 1.
