Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run

enyata [817]

To find the answer, you first must find how many yards Charlie can run in a minute. Since there are 60 seconds in a minute, you multiply 3 times 60, which is 180. Then you must multiply this number by 60 again, because there are 60 minutes in an hour. This equals 10,800, your answer.

Charlie can run 10,800 yards in an hour.

Jordan has 5/6 dvds as bob, so if jordan has 55 dvds how much does bob have?

Luba_88 [7]

Answer:

Bob has 66 dvds

Step-by-step explanation:

Let's assume

Bob has 'x' number of dvds

we are given

Jordan has 5/6 dvds as bob

so, Jordon will have

$=\frac{5}{6}x$

now, we are given jordan has 55 dvds

so, we can set it to 55

and then we can solve for x

$\frac{5}{6}x=55$

Multiply both sides by 6

$6\times \frac{5}{6}x=6\times 55$

$5x=6\times 55$

divide both sides by 5

$\frac{5x}{5} =\frac{6\times 55}{5}$

$x=66$

So,

Bob has 66 dvds

What is the length in feet of the base of the triangle?

worty [1.4K]

$\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ A=\frac{2}{5}\\ h=\frac{6}{5} \end{cases}\implies \cfrac{2}{5}=\cfrac{1}{2}b\left( \cfrac{6}{5} \right)\implies \cfrac{2}{5}=\cfrac{6b}{10}\implies \cfrac{2}{5}=\cfrac{3b}{5} \\\\\\ 10=15b\implies \stackrel{\textit{dividing both sides by 15}}{\cfrac{10}{15}=\cfrac{15b}{15}}\implies \cfrac{10}{15}=b\implies \cfrac{2}{3}=b$
