Answer: 18 Bows

Step-by-step explanation:

Make a proportion

\frac{9 bows}{7 minutes} =\frac{x}{14 minutes}

Cross multiply, so do 9 x 14 and 7 x X.

126 = 7x

Divide 126 by 7 to get the answer.

\frac{126}{7} = 18 bows

adoni [48]

Answer:

4m is the answer.

Step-by-step explanation:

a = 3m

b = ?

c = 5m

According to the Pythagoras theorem,

a² + b² = c²

3² + b² = 5²

9 + b² = 25

b² = 25 - 9

b² = 16

b = 4m

∴ The distance between the ladder and the bottom of the slide is 4m.

Find the exact value by using a half-angle identity.<br><br> tan seven pi divided by eight
murzikaleks [220]

Answer:

  1 -√2

Step-by-step explanation:

  \tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}

tan(7π/8) = 1 -√2
