altitude=√(8²-4²)=4√(2²-1²)=4√3

15.

x÷6=cos 60°

x=6×cos 60°=6×1/2=3

perimeter=18+6+(3+18+3)+6=54

16.

10√3÷PQ=sin 30°=1/2

PQ=20√3

10√3÷PR=sin 60°=√3÷2

PR=2×10√3÷√3=20

QR=√(20²+(20√3)²)

=√(400+1200)

=√1600

=40

perimeter=20+40+20√3=60+20√3

Agata [3.3K]

Answer:

Ratio as a fraction in simplest form is, $\frac{\text{17 correct}}{\text{3 incorrect}}$

Step-by-step explanation:

Ratio defined as the relationship between the quantities of something i.e,

a: b = $\frac{a}{b}$

Given: 51 correct : 9 incorrect

By definition of ratio:

51 correct : 9 incorrect = $\frac{\text{51 correct}}{\text{9 incorrect}}$

Divide both numerator and denominator by 3 we get;

$\frac{\text{17 correct}}{\text{3 incorrect}}$

then

The ratio as a fraction in simplest form is, 17 correct : 3 incorrect or $\frac{\text{17 correct}}{\text{3 incorrect}}$
