The motorcycle engine on a kawasaki ninja 1000 has a displacement of 1043 cubic-centimeters (cm3). in order to calculate its eng
marishachu [46]

\boxed{\boxed{ \ 0.061 \frac{inch^3}{cm^3}\ }}

<h3>Further explanation</h3>

We will calculate the unit conversion factor used to convert its engine displacement from cubic-centimeters to cubic-inches.

The relationships between inch and cm are as follows:

\boxed{ \ 1 \ inch = 2.54 \ cm\ }

Inches and cm represent units of length.

Made into fractions, 1 inch as the denominator and 2.54 cm as the numerator.

\boxed{ \ \frac{1 \ inch}{2.54 \ cm} \ }

As a unit conversion factor of volume, the numerator and the denominator in cubic.

\boxed{ \ \frac{(1 \ inch)^3}{(2.54 \ cm)^3} \ }

\boxed{ \ \frac{1 \ inch^3}{16.387 \ cm^3} \ }

Thus, we get the unit conversion factor

\boxed{\boxed{ \ 0.061 \frac{inch^3}{cm^3}\ }}

Let's use this unit conversion factor to calculate its engine displacement in new units.

\boxed{= 1,043 \ cm^3 \times 0.061 \ \frac{inch^3}{cm^3}}

Note for cm³ units that have been crossed out.

The conversion result is \ \boxed{ \ 63.623 \ inch^3\ }

What is 7x+1-4+4+1+435
lisabon 2012 [21]

Answer:

the answer is 7x + 437

Step-by-step explanation:

1) 7 is the only number with a variable, <em>x</em>, so it will remain as it is.

2) -4+4= 0

3)1+1= 2

4) 2+435= 437

7) combine 7x and 437 together. 7x + 437.

We cant go any further, because 7x and 437 are not liketerms.
