Cross multiply: 60%/100% =21/x
X is the variable we are trying to find.
100*21=2,100
2,100/60
X =35
All together in the choir there are 35 members.

I hope this helps!

The value of a professional basketball player's autograph rose 20% in the last year. It is now worth $336.00. What was it worth
sesenic [268]

Answer:

The value of basketball player's autograph a year ago is $280

Step-by-step explanation:

Given as :

The present value of autograph = $ 336.00

The rate of increase of autograph = 20%

The time period = 1 year

Let The value one year ago = $ x

So ,

The value of autograph after n year = The present value × (1+\frac{Rate}{100})^{n}

Or, $ 336.00 = $ x × (1+\frac{20}{100})^{1}

Or, $ 336.00 = $x × 1.2

∴ x = \frac{336.00}{1.2} = $280

Hence The value of basketball player's autograph a year ago is $280 Answer

Answer:

<em></em>Height = 173.8ft<em></em>

<em></em>

Step-by-step explanation:

Given

\theta = 40^o

d = 200ft --- distance from building

h=6ft--- height of the building

Let the height of the building be H. So:

\tan(\theta) = \frac{Opposite}{Adjacent}

\tan(40) = \frac{H}{200}

Make H the subject

H = 200 * \tan(40)

H = 167.82

The required height s:

Height = H + h

Height = 167.82 + 6

Height = 173.82ft

<em></em>Height = 173.8ft<em> --- approximately</em>
