Hawick is 1515 miles south of Abbotsford, and Kelso is 1717 miles east of Abbotsford. What is the distance from Hawick to Kelso?

Mashcka [7]

Answer:

As per the statement:

Hawick is 15 miles south of Abbotsford, and Kelso is 17 miles east of Abbotsford.

Let H represents Hawick , A represents Abbotsford and K represents Kelso

See the diagram as shown below:

Distance of AH = 15 miles

Distance of AK = 17 miles.

We have to find the distance HK:

Using Pythagoras theorem;

$\text{Hypotenuse side}^2 = \text{Adjacent side}^2 + \text{opposite side}^2$

then;

$\text{HK}^2 = 15^2+17^2 = 225 + 289 = 514$

$HK = \sqrt{514} =22.671581$ miles.

Therefore, the distance from Hawick to Kelso( to the nearest tenth place) is 22.6 miles

If x= 5 and y= 2, then xy =

seropon [69]

Answer:

You cant find that out. X and Y are like two different animals in a zoo, and XY is a whole other animal, you cant combine two animals in the same cage, so X and Y cant turn into XY. You could do:

X = 5

Y = 2

X + Y = ?

In this case the answer would be seven.
