Change 179km to miles. Type a whole number or a decimal. Round to four decimal places as needed.
atroni [7]

Answer:

179/1.60934 miles then divide to get the whole number/ decimal.

Step-by-step explanation:

A quick search tells me there are 1.60934 km in 1 mile.  

To convert from one unit to another there is a super simple method.  Set up a fraction with the two values, so in this case 1/1.60934  or 1.60934/1.  Which do you use?  well it depends which you are tryng to convert.

1.60934/1 has the units km/miles so since miles is on the bottom we would use it to convert miles.  That's hat you have to look at, what is in the denominator.  Since we are converting 179 km we want km on the bottom.

So we use 1/1.60934 instead because the units are miles/km.  now you just multiply the 179 by the fraction.  so the answer is 179/1.60934 miles.

Now it says we need a whole number of decimal, can you handle the division?

If y= x+3/6-x, what is the value of y when x =7i?
djverab [1.8K]

Answer:

Option (2)

Step-by-step explanation:

Given :  y = \frac{x+3}{6-x}

If x = 7i

y = \frac{7i+3}{6-7i}

By simplifying denominator of the given rational expression,

y = \frac{7i+3}{6-7i}\times \frac{6+7i}{6+7i}

y = \frac{(7i+3)(6+7i)}{6^2-(7i)^2}

y = \frac{7i(6+7i)+3(6+7i)}{36-49i^2}

y = \frac{42i+49i^2+18+21i}{36+49} [Since, i² = (-1)]

y = \frac{63i-49+18}{85}

y = \frac{63i-31}{85}

y = -\frac{31}{85}+\frac{63}{85}i

Therefore, Option (2) is the correct option.

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
Y_Kistochka [10]
Ur independent variable is ur x values....ur dependent variable is ur y values..so if hrs are on the x axis, then ur independent values are ur hrs (or time)....and ur dependent values are ur distance.

(0,0),(2,50)
slope = (50 - 0) / (2 - 0) = 50/2 = 25

y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr

how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles

in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.
