Speed=distance/time

we need to findn her distance in miles and times in hous

440 yards times 4 laps=1760 yards
1760 yards=1 mile

distance=1 miles

time
10 minutes
60 minutes per hour
1/6 hour
1 miler per (1/6) hour
multiply by 6
6 miles per 1hour

Lin is playing hand ball and wants the ball to bounce off wall CB and land at D. Where on the wall should she aim if she's stand
ASHA 777 [7]

The triangles formed by the path of the ball and the wall in the given diagram are similar triangles.

<h3>Correct Response;</h3>

The point on the wall she should aim is; <u>A. 7.8 feet away from point B</u>

<h3 /><h3>Method by which the above value is obtained;</h3>

The possible diagram in the question is attached

Let <em>x</em> represent the distance from point <em>B</em> where the ball lands.

ΔCDE is similar to ΔABE, by Angle-Angle similarity postulate.

By trigonometric ratio, the tangent of the angles ∠CDE and ∠BAE are;

tan(\angle CDE) = \mathbf{\dfrac{20 - x}{25}}

tan(\angle BAE) = \mathbf{ \dfrac{x}{16}}

tan(∠CDE) = tan(∠BAE)

Therefore;

\dfrac{20 - x}{25} = \dfrac{x}{16}

Which gives;

16 × (20 - x) = 25·x

320 = 41·x

x = 320 ÷ 41 ≈ 7.8

The point on the wall she should aim if she's standing at point <em>A</em> is therefore;

  • <u>A, 7.8 feet away from point </u><u><em>B</em></u>

you need to variables

M= represents the amount of months she goes to the gym

X= represents the total that she paid

$75(fee)+32·M($ per month)=X(the total)
