Which single conversion factor would you use to find out how many miles are in 8,462 yards?

ValentinkaMS [17]

Answer:

A. 1 mile / 1,760 yards

Step-by-step explanation:

A single conversion factor is a number that we can multiply directly with 8,462 yards to determine how many yards are there in 8,462 yards.

Since 1 mile is to 1,760 yards, the single conversion factor to use in determining how many miles a number of yards would be = 1 mile/1,760 yards = $\frac{1}{1,760}$

Thus, to find out many miles are in 8,462 yards, multiply by $\frac{1}{1,760}$ .

$8,462*\frac{1}{1,760} = \frac{8,462}{1,760} = 4.8$ miles

What is the fraction 2 over 3 written in decimal form!!!!!!!!!

vodomira [7]

This is a number you will have memorized in grade school. If not, you can always perform long division of 2 by 3 to find it---or ask your calculator.

2/3 = 0.6666_6 . . . . . . repeating 6s indefinitely

____
Most folks get tired of writing 6s after a couple million of them, so they round it off to 0.67 or 0.667. These rounded values are NOT exactly 2/3.

Let f ( x , y )=5 x and let C be the segment of the parabola y = 2 x squared joining O( 0 , 0 ) and P( 1 , 2 ). a. Find a parame

taurus [48]

a. We can parameterize $C$ by

$x=t$

$y=2t^2$

with $0\le t\le1$ . Then

$\displaystyle\int_C5x\,\mathrm dS=\int_0^15t\sqrt{1+16t^2}\,\mathrm dt=\dfrac5{48}(17^{3/2}-1)$

b. We can parameterize the opposite direction by instead setting

$x=1-t$

$y=2(1-t)^2$

with $0\le t\le 1$ . Then

$\displaystyle\int_C5x\,\mathrm dS=\int_0^15(1-t)\sqrt{1+16(1-t)^2}\,\mathrm dt=-\int_1^05u\sqrt{1+16u^2}\,\mathrm dt=\int_0^15u\sqrt{1+16u^2}\,\mathrm du$
