146-5=141
ratio=1:4
1+4=5
141÷5=28.2

5.100 x 10⁻³ = 5.100 x 0.001
= 0.005100 (shift the decimal point for 5 by 3 units left)
Alternatively, because 10⁻³ = 1/1000, therefore
5.100 x 10⁻³ = 5.1/1000
0.0051

This yields the same result.
Answer: b. 0.005100
Step-by-step explanation:
1) 7/23 + 11/23 + 9/23
7+11+9/23
27/23
= 1 4/23
2) 2 5/7 + 9 4/7
11 9/7
= 11.12
3) 9/20 + 3/5
9+12/20
21/20
= 1 1/20 or 1.05
Answer:
sin B= 0.096288
B = 5.525°
Step-by-step explanation:
Consider ΔABC as shown in figure attached
From figure:
a = 1 m
b = 3.54 m
sin A = 0.0272
sin B = ?
Using the sine rule for non-right-angle triangle
