That’s the commutative property.
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
Answer:
i cant see
Step-by-step explanation:
8. complementary angles = 90°
3x+3+10x-4 = 90
13x-1 = 90
13x = 91
so x = 91/13= 7
then K = 3(7)+3 = 24°
so L = 10(7)-4 = 70-4 = 66°
9. P is three less than twice of Q
so P = 2Q-3
supplementary angles = 180°
P+Q = 180
(2Q-3)+Q = 180
3Q-3 = 180
3Q = 183
so Q = 183/3 = 61°
then P= 2(61)-3 = 122-3 = 119°
10. B is two more than three times of C so B= 3C+2
complementary angles = 90°
B+C= 90
(3C+2)+C=90
4C+2=90
4C= 88
so C= 22°
then B = 3(22)+2= 66+2 = 68°
I don’t either
Can someone please teach me
