What is the height of the building pictured below if its shadow is 100 ft. long?
Evgen [1.6K]
Yeah.. baby, do the SOH CAH TOA with the hula hoop

\bf 
sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}


so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which  of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so  \bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}

solve for "h"

What is 25% of 400 5% of 20
stiks02 [169]

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1


I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.

Answer:

(B) 20

Step-by-step explanation:

Let small puppet be represented by-----------------s

Let large puppet be represented by-----------------l

Total number of puppets expression will be: s+l =25---------a

The expression for total costs will be : 1$ s + $2l=$30-------b

Equation a can be written as; s= 25-l ------------c

Use equation c in equation b as

$1( 25-l )+$ 2l = $30

25-l + 2l = 30

25+l =30

l= 30-25 =5

l, large puppets = 5

s, small puppets = 25-5 = 20

Answer choice A is incorrect because 25 is the total number of all puppets

Answer choice C and D are incorrect because the numbers are less that that of small puppets.
