ABC is similar to PQR
that means AC/PR is a constant = 12/ 6 = 2
AC= 2 PR
AB= 2PQ
BC= 2QR
Perimeter of ABC= AB+BC+ CA=
2PQ + 2 QR + 2PR= 2( PQ+ QR+ PR)
= 2( perimeter of triangle PQR )
Perimeter of ABC= 2( perimeter of PQR) = 2* 36 = 72
Answer : 72.
-3x + 4y = -6
20x - 4y = 40
-----------------------
17x = 34
x = 2
5(2) - y = 10
10 - y = 10
y = 0
the correct answer is D. (2,0)
Answer:
Equal to.
Step-by-step explanation:
The easiest way to figure this out is to convert 14,400 seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour. So, divide 14,400/60, which is 240. This is now 240 minutes. To figure out minutes into hours, divide 240/60, which is 4. 4=4, so 4 hours equals 14,400 seconds.
Hope this helps you out...have a good day c:
Answer:
x = 1.87
Step-by-step explanation:
2x^2 - 5 + 1 = 3
2x^2 = 3 + 5 - 1
2x^2 = 7
x^2 = 7/2
x = √3.5
x = 1.87082.....
x = 1.87 ( 3 significant figures )
