SOH CAH TOA

You would use CAH for this question because you are told to find the length for BC, which is the hypotenuse and you are told the adjacent line is 6.3cm.

H=A÷C

=6.3÷cos(71)

=19.3507869666

H=19.4 (rounded to 3 significant figures)

Amiraneli [1.4K]

Answer:

$38.46

15% /100% x $256.38

0.15 x $256.38

$38.46

Her minimum payment is $38.46

There are 36 ribbons of which 1/5 are yellow, 7/15 are pink and the remaining ribbons are

Kay [80]

Step-by-step explanation:

Let there be x blue ribbons

$\therefore \: \frac{1}{5} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{1 \times 3}{5 \times 3} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{3}{15} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{3 + 7}{15} + x = 36 \\ \therefore \: \frac{10}{15} + x = 36 \\ \therefore \: x = 36 - \frac{10}{15} \\ \therefore \: x = \frac{36 \times 15 - 10}{15} \\ \therefore \: x = \frac{540 - 10}{15} \\ \therefore \: x = \frac{530}{15} \\ \therefore \: x = 35\frac{5}{15} \\ \\ \therefore \: x = 35\frac{1}{3} \: are \: blue. \\$
