ruben made a scale drawing of a petting zoo. the scale of the drawing was 1 millimeter : 10 meters. if the actual length of the
Sedaia [141]

The length of the pen in the drawing will be 2 millimeters.

As we can't create a real-life dimension in a  small sheet of paper,  we opted for a small scale that covers up the large length.

As we are given, the scale of the drawing is 1 millimeter: 10 meters, which is 1 millimeter for every 10 meters

As we have been given that the  actual  size of the goat pen  is 20 meters, so the length of the pen in the drawing is =  20*(1/10)

                                                                                   =   2 millimeters

Keith's height and his nephews height was at a ratio of 15:7 then, keith's Height increased by 16% and his nephews height double
Vikentia [17]

Answer:

311.6 cm

Step-by-step explanation:

To solve this problem, let's call:

k = Keith's height

n = nephew's height

Since the ratio is 15:7, we have

\frac{k}{n}=\frac{15}{7}\\k=\frac{15}{7}n (1)

Then, Keith's height is increased by 16%, so the new height of Keith is

k'=k+0.16 = 1.16k  (2)

While the nephew's height is doubled:

n'=2n (3)

We also know that Keith is now 34 cm taller than his nephew, so

k'=n'+34 (4)

Substituting (2) and (3) into (4), we get

1.16k=2n+34

And substituting (1),

1.16\cdot \frac{15}{7}n=2n+34

Solving for n,

2.49n=2n+34\\\\0.49n=34\\n=\frac{34}{0.49}=69.4

So the current height of the nephew is:

n'=2n=2(69.4)=138.8 cm

While Keith's current height is

k'=138.8+34=172.8 cm

So their total current height is

k'+n'=172.8+138.8=311.6 cm
