20 degrees. i have a protractor, and its really helpful! you should use one.
since 1.5 is half of 3.0 all ouj havr t o do is multiply by 2 2.4*2=4.8 answer
Well here are 3
(0,7);(1,11);(2,15)
4(0) + 7 y:7
You can keep doing it choose a number for x that's and for y multiply 4 times the numer you choosed for x and add 7 to it
13. Pick a point and see which formula works.
Ay = -4, A'y = 7. Only the formula of selection D makes that translation.
14. Use the compound interest formula A = P*(1 +r/n)^(nt).
..1500*1.015^80 = 4935.99, matching selection C
15. The lid has a perimeter of 90", so the area of the sides is
.. 90" * 24" = 2160 in^2
The area of the lid is
.. 30" * 15" = 450 in^2
The gray area is (2160 -450) in^2 = 1710 in^2 larger, corresponding to selection C.
16. The only formula that maps (7, -1) to (21, -3) is that of selection D.
