Nezavi [6.7K]

Answer: They are away for $2\dfrac{3}{4}\ hours$ from home.

Step-by-step explanation:

Since we have given that

Time to get there = $\dfrac{1}{4}$

Time to get back = $\dfrac{1}{4}$

Number of soccer games = 3

Time for each soccer games = $\dfrac{3}{4}$

So, total time for 3 games would be

$3\times \dfrac{3}{4}=\dfrac{9}{4}$

So, the time for which they will be away from home is given by

$\dfrac{1}{4}+\dfrac{9}{4}+\dfrac{1}4}=\dfrac{1+9+1}{4}=\dfrac{11}{4}=2\dfrac{3}{4}\ hours$

Hence, they are away for $2\dfrac{3}{4}\ hours$ from home.

Ierofanga [76]

Answer:

The length of the ladder = 6.5077 ft

Step-by-step explanation:

Given A ladder leans against the side of a house

Given the angle of elevation of the ladder is 66° when the bottom of the ladder is 16 ft from the side of the house

Let 'C' be the point of observation.

Given CA= 16 ft

From right angle triangle

$cos C = \frac{CB}{CA}$

$cos 66 = \frac{x}{16}$

x = 16 × cos 66°

x = 16 × 0.4067

x = 6.5077

x = 6.5 ft

The length of the ladder = 6.5 ft
