Answer:
Yes
Step-by-step explanation:
To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.
a^2 + b^2 = c^2
12^2 + 16^2 = 20^2
Evaluate the exponents.
144 + 256 = 400
Add them together.
400 = 400
Since a^2 and b^2 add up to equal c^2, this is a right triangle.

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
3x- 5y = -2
2x+y= 3 | *5
3x - 5y= - 2
10x+ 5y=15
13x=15-2
13x=13
x=13:13
x=1
2*1+ y= 3
2 + y=3
y=3-2
y=1
75.89 + 0.12x = 27.41 + 0.36x
75.89 - 27.41 = 0.24x
48.48 = 0.24x
x = 48.48 / 0.24
x = 202
