Answer:
Q5) 6.5833 (rounded to nearest 4 d.p.)
Q6) [tex]\frac{3}{10}[/tex]
Step-by-step explanation:
Q5) [tex]\sqrt{2.38 + 6.4^{2} }[/tex] = [tex]\sqrt{2.38 + 40.96}[/tex]
= [tex]\sqrt{43.34}[/tex]
≈ 6.5833 (rounded to nearest 4 d.p.)
Q6) When working with mixed numbers, I would change them to improper fractions first for easier calculations.
1[tex]\frac{3}{4}[/tex] × [tex]\frac{6}{35}[/tex] = [tex]\frac{7}{4}[/tex] × [tex]\frac{6}{35}[/tex]
= [tex]\frac{42}{140}[/tex] (Simplify by dividing by 2)
= [tex]\frac{21}{70}[/tex] (Simplify by dividing by 7)
= [tex]\frac{3}{10}[/tex]
