9514 1404 393

Answer:

  49.3 feet

Step-by-step explanation:

Shadow lengths and object heights are considered to be proportional, so we have ...

  tree height/(tree shadow) = Andrew's height/(Andrew's shadow)

  height / (85 ft) = (5.8 ft)/(10 ft)

  height = (85 ft)(5.8/10) = 49.3 ft

The tree is 49.3 feet tall.

A certain stock starts the day at $273/8 per share. If it drops $21/2 during the day, what is its closing value? A. $247/8 B. $2
Elza [17]

Answer:

A. $ 24 7/8

Step-by-step explanation:

GIVEN: A stock starts the day at $27 3/8 per share.

             Share drops $2 1/2 during the day.

To Find : Closing value

Solution : first we need to find how many 1/8 are there in 1/2

So, \frac{\frac{1}{2} }{\frac{1}{8} } =4

when share drops by $2 then  share will be :

$27 - $2 =$25


and \frac{3}{8} - 4(\frac{1}{8})


⇒\frac{3}{8} - \frac{4}{8}


⇒\frac{-1}{8}


So, 25-\frac{1}{8}


⇒24\frac{7}{8}

So, its closing value is 24\frac{7}{8}.
