Since the coordinate system is rectangular, we have the matrix
[ x ]
[ y ]
The transformation matrix is
[ cos 120 sin 120 ] [ x ] = [ x' ]
[ -sin 120 cos 120 ] [ y ] = [ y' ]<span />
Answer:
she has to payback the bank 7,920 but she borrowed 7,500 so the amount of interest is 420 dollars because thats how much she needs to pay more.
per month she pays 330.
i guess that is 330 percent of 7,920 idk.
Step-by-step explanation:
330 x 24 = 7,920.
7,920-7,500 = 420
Percent change: (new value - old value)/old value * 100
((10-2.50)/2.50) = 3 * 100 = 300%
There is a 300% increase
Answer:
30 minutes each evening
Step-by-step explanation:
5.25 / 7 = 0.75 hours each day = 45 minutes
45 - 15 = 30 minutes
Answer:
No
Step-by-step explanation:
Similar triangles must have the exact same angles
All angles must add to a total of 180° so to find x you can do 85°+64°=149° this means that 149°+x°=180° to find that you can do 180°-149° which equals 31°.
Then you do the same for the second triangle
1. 26°+85°=111°
2. 180°-111°=69°
because 69 and 31 aren't the same number these triangles aren't similar
similar triangles must have all the same angle amounts.
