Cody bought a hamburger for $3 and
Elza [17]
The answer would be 20-(3+2) because first you do what is inside the parentheses 3+2=5 and now you have to subtract 20-5=15. Cody’s change should be $15.

A dragonfly traveled at a rate of 35 miles per hour for 2.5 hours. What distance did the dragonfly travel?
igomit [66]

The dragonfly traveled a distance of 87.5 miles at a rate of 35 miles per hour.

Explanation:

Distance traveled by butterfly at the rate of 34 miles per hour in 2.5 hours
=35 mi/hr × 2.5 hour
=<span><span>35mi</span><span>hour</span></span> ×2.5 <span>hour</span>
=<span>35mi⋅<span>2.51</span>⋅<span>1010</span></span>
=<span>35mi⋅<span>2510</span></span>
=<span>35mi⋅<span>52</span></span>
=<span>175m<span>i2</span></span>
=<span>87.5mi</span>

∴ It would travel a distance of 87.5 miles.
Here mi represents miles.

Suppose that y varies inversely as x and that y=8 when x=3. Calculate the value of y when x= 10.
Svetach [21]

\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{we know that } \begin{cases} y = 8\\ x = 3 \end{cases}\implies 8=\cfrac{k}{3}\implies 24=k~\hfill \boxed{y = \cfrac{24}{x}} \\\\\\ \textit{when x = 10, what is \underline{y}?}\qquad \qquad y = \cfrac{24}{10}\implies y = \cfrac{12}{5}

Pls help With this question thank you
Lapatulllka [165]

Answer:

CD=4 \text{ cm }

Step-by-step explanation:

We have a similarity of triangles. Once the side BC and ED are parallel,

$\frac{BC}{AC} =\frac{ED}{AD} $

$\frac{10}{AC} =\frac{5}{4} $

Once AC=AD+CD \Rightarrow AC=4+CD

$\frac{10}{4+CD} =\frac{5}{4} $

5CD+20=40

5CD=20

CD=4 \text{ cm }
