A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s.
0 * s =0
4 * s = 10
6 * s = 15
s= 10/4=15/6=2.5
The scale factor of the dilatation is 2.5. It is shown in the attachment.

Subtract 13/16 from 3/8

Artemon [7]

In order to subtract the fractions, they need to have the same denominator.

So, to put the fractions in the same denominator, let's find the least common multiple between them:

$\begin{gathered} 16\to2\cdot2\cdot2\cdot2 \\ 8\to2\cdot2\cdot2 \\ \\ \text{LCM}\to2\cdot2\cdot2\cdot2=16 \end{gathered}$

So, calculating the subtraction, we have:

$\frac{13}{16}-\frac{3}{8}=\frac{13}{16}-\frac{6}{16}=\frac{7}{16}$

So the resulting fraction is 7/16.

A hot air balloon went from an elevation of 4,294 feet to an elevation of 3,412 feet in 36 minutes. What was its rate of descent

Cloud [144]

The hot air balloon traveled 882 feet in 36 minutes. To find out the number of ft/min, we divide 882 by 36. 882/36=24.5
So, the hot air balloon descended 24.5 ft/min
