Answer:
a) 38 mg
b) 230 Exa-g
c) 24 ng
d) 8 Eg
e) 4.2 g
Step-by-step explanation:
Given:
a) 3.8×10⁻⁵ kg
1 kg = 10⁶ mg
Multiply the above value by 10⁶
we get
3.8×10⁻⁵ × 10⁶ = 38 mg
b) 2.3 × 10¹⁷ kg
or
2.3 × 10²⁰ g
1 exa = 10¹⁸
multiply by 10⁻¹⁸
we get
230 Exa-g
c) 2.4 × 10⁻¹¹ kg
or
24 × 10⁻⁹ g
1 g = 10⁹ ng
thus,
24 × 10⁻⁹ g × 10⁹ = 24 ng
d) 8×10¹⁵ kg
or
8 × 10¹⁸ g
1 exa gram = 10¹⁸ g
( 8 × 10¹⁸ ) × 10⁻¹⁸ = 8 Eg
e) 4.2 × 10⁻³ kg
or
4.2 × 10⁻³ × 10³ = 4.2 g
I can't tell you the answer but I can tell you what to do. First you have to take what is in parentheses first. x-4... But I think you made this up because your not supposed to put 10× but the 8(x-4) that makes sense but the last part doesn't..
<span>The correct answer is: Option (D) Human body
Explanation:
Measurements were first based on the parts of human body. For example the old Eygptian "cubit" was the unit of length. It was measured by using the forearm.
1 cubit = The length from the elbow of the forearm to the tip of the middle finger.
In a nutshell, it is the human body that was used as the reference to measure things up.</span>
So, put your "x's" together first and then your intercepts. That should answer your question :)
1. The car is 10km/h faster than the bus
Explanation:
50/2.5=20
50/5=10
20-10=10
2. m=-1.5
Explanation
5+7=12
-5-3=-8
12/-8=-1.5
