Answer:

b = 36

Step-by-step explanation:

Assuming this is a right triangle with hypotenuse = c and legs a and b

Then using Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + b² = c², and substituting values

15² + b² = 39², that is

225 + b² = 1521 ( subtract 225 from both sides )

b² = 1296 ( take the square root of both sides )

b = $\sqrt{1296}$ = 36

A coordinate grid is placed over a map and every unit represents 1 mi. The point at (3, 8) represents the location of the baseba

alexira [117]

The distance between 2 points $( x_{1}, y_{1})$ and $( x_{2}, y_{2})$ on the coordinate plane is $\sqrt{(x_{2}-x_{1})^2-(y_{2}-y_{1})^2}$
So the distance between the given points is $\sqrt{(7-3)^2+(-2-8})^2}= \sqrt{4^2+(-10)^2}= \sqrt{16+100}= \sqrt{116}=10.8$
As every unit is 1 mile, so the distance should be 10.8*1=10.8miles.

Hope this helps.

A ticket costs £656<br> Last year it cost £640<br> What percentage increase is this ?

evablogger [386]

Answer:

2.5%

Step-by-step explanation:

656 / 640 = 1.025

1.025 into percent is 102.5%

102.5% - 100% = 2.5

640 + 2.5% of 640 = 656

BOOM
