From 1970 to 1980 the consumer price index(cpi)increased from 38.8 to 82.4. if a dozen eggs cost $0.25 in 1970 and price of egg increased at the same rate ae the cpl from 1970 to 1980 approximately how much did a dozen cost n 1980

its 4 because 2 times 2 is 4, if you double the number two you get four

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
