In order to prove that two lines are parallel to each other, you need to show that they have the same slope.
Line 1 is perpendicular to a line that has slope m, thus it has a slope of -1/m.
Line 2 is perpendicular to the same line with slope m, thus it has a slope of -1/m.
Line 1 and Line 2 have the same slope so they are parallel.
Answer:
⇒Let the no. of call minute be = x
⇒& no. of text messages be = y
⇒As total number of minutes used and text messages sent last month was 561
So x + y = 561.................................(1)
⇒Now as call minutes cost 8 cents each and text messages cost 5 cents each and her bill was $34.26
So 8x + 5y = 3426............................(2)
On solving equation 1 & 2 we have
we got x = 354 cent
& y = 207 cent
I believe the ramps volume is 190ft.
Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
Ivan needs to walk the dog 6 more times. 8(5)=40 you subtract 40 from 88 and get 48. 8(6) is 48. When Ivan walks the dog 6 times he will earn 48. 48+40 is 88.
