The scale factor on a scale drawing of machine part is 15 1 /8. If the part is 3 7/8 inches long as the drawing, how long is the

Marta_Voda [28]

Answer:

Option D) 58 39/64 inches

Step-by-step explanation:

we know that

The scale drawing is

$15\frac{1}{8}$

convert to an improper fraction

$15\frac{1}{8}=\frac{15*8+1}{8}=\frac{121}{8}$

That means

121 in in the actual, represent 8 in on a scale drawing

To find how long is the actual part for 3 7/8 inches long as the drawing

Apply proportion

First convert to an improper fraction

$3\frac{7}{8}=\frac{3*8+7}{8}=\frac{31}{8}$

$\frac{121}{8}\frac{actual}{drawing} =\frac{x}{(31/8)}\frac{actual}{drawing}\\ \\x=121(31/8)/8\\ \\x=\frac{3,751}{64}\ in$

convert to mixed number

$\frac{3,751}{64}\ in=\frac{3,712}{64} +\frac{39}{64} =58\frac{39}{64}\ in$

What is the answer to (9/10 - 2/5) - 1/3 and how do u get the answer

Oksanka [162]

$(\frac{9}{10}-\frac{2}{5})-\frac{1}{3}=\ \ \ \ \ | make\ a\ common\ denominator\\\\
(\frac{27}{30}-\frac{12}{30})-\frac{10}{30}=\ \ \ | omit\ the\ bracket\\\\\frac{27}{30}-\frac{12}{30}-\frac{10}{30}=\frac{27-12-10}{30}=\frac{5}{30}=\frac{1}{6}\\\ Solution\ is\ \frac{1}{6}.$

What is the sum of the arithmetic series

docker41 [41]

Answer:

$S_ {12} = 192$

Step-by-step explanation:

The nth term of the given arithmetic sequence is

$U_n = 3 + 2n$

The first term of this series is:

$U_1 = 3 + 2(1) = 5$

The last term of this series is when

$n = 12$

$U_ {12}= 3 + 2(12)$

$U_ {12}= 3 + 24 = 27$

The sum of the first n terms of an arithmetic series when the first an last term is known is given by:

$S_n = \frac{n}{2}(a + l)$

Where a=5 is the first term and l=27 is the last term.

$S_ {12} = \frac{12}{2}(5 + 27)$

$S_ {12} =6(32) =19 2$
