Answer:

Yes she can.

Step-by-step explanation:

Val can make 6 slides in an hour.

1/6 * 60 minutes = 10 minutes. per slide

10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.

=====================

In one hour, she can produce 6 slides.

In two hours, she can produce 12 slides (2 * 6 = 12)

Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.

For a project in his Geometry class, Mamadou uses a mirror on the ground to measure the height of his school's football goalpost
andreev551 [17]

Answer:

Height of the goalpost is 9.25 m.

Step-by-step explanation:

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

\frac{AB}{ED}= \frac{CB}{CD}

\frac{1.75}{ED}=\frac{2.6}{13.75}

ED = \frac{1.75\times 13.75}{2.6}

ED = 9.25 m

Height of the goalpost is 9.25 m.
