Answer:

20.25

Step-by-step explanation:

i think its asking for the long side

the pythagorean theorem states that in a right triangle a^2+b^2=c^2

a is 19

b is 7

c is the long side

19^2= 361

6^2= 49

361+49=410

410 =c^2

square root of 410 = ~20.25

Answer:

hypotenuse =  \sqrt{ {19}^{2} + {7}^{2}}   \\  =  \sqrt{361 + 49}  =  \sqrt{410}  \\  = 20.25

20.25 is the right answer.

Vladimir [108]

Answer:

B

Step-by-step explanation:

The sum to n terms of a geometric series is

S_{n} = \frac{a(1-r^{n}) }{1-r}

where a is the first term and r the common ratio

Here a = 6144 and r = \frac{a_{2} }{a_{1} } = \frac{3072}{6144} = \frac{1}{2} , then

S_{10} = \frac{6144(1-(\frac{1}{2}) ^{10}) }{1-\frac{1}{2} }

     = \frac{6144(1-\frac{1}{1024}) }{\frac{1}{2} }

     = 12288(1 - \frac{1}{1024} ) ← distribute

     = 12288 - 12

     = 12276 → B

A box of pencils is 5 1/4 inches wide. Seven pencils, laid side by side, take up 2 5/8 inches of the width. How many inches of t
Andre45 [30]

Answer:   Width of box is not taken up by pencils =  2\dfrac58\text{ inches}

Width of each pencil =\dfrac38\text{ inches}

Step-by-step explanation:

Given: Width of pencil box = 5\dfrac14\text{ inches}=\dfrac{21}{4}\text{ inches}

Width of seven pencils = 2\dfrac58\text{ inches}=\dfrac{16+5}{8}\text{ inches}=\dfrac{21}{8}\text{ inches}

Width of box is not taken up by pencils =  Width of pencil box  - Width of seven pencils

\left \{ {{y=2} \atop {x=2}} \right. \dfrac{21}{4}-\dfrac{21}{8}\\\\=\dfrac{21\times2-21}{8}\\\\=\dfrac{21}{8}\text{ inches}=2\dfrac58\text{ inches}

Width of box is not taken up by pencils =  2\dfrac58\text{ inches}

Width of each pencil = (Width of seven pencils ) ÷ 7

=\dfrac{21}{8}\div7\\\\=\dfrac{21}{8}\times\dfrac17\\\\=\dfrac38\text{ inches}

Width of each pencil =\dfrac38\text{ inches}
