Acompany produces metal slabs for industrial use. the slabs come in three thicknesses: 5in, 10in., 15 in. the weights of each thickness for each metal are given below. metal 1: 150lbs, 300lbs, 600lbs metal 2: 130lbs, 260lbs, 390lbs metal 3: 310lbs, 620lbs,930lbs metal 4: 140lbs, 280lbs, 420lbs for which of the metals weight not proportional to the thickness? a.) metal 1 b.) metal 3 c.) metal 4 d.) metal 2

5, 10 ,15  

divide each by 5

1,2, 3

so the ratios should be 1,2,3

Metal 1 : divide by 150

1,2,4

Metal 2 divide by 130

1,2,3

Metal 3  divide by 310

1,2,3

Metal 4 divide by 140

1,2,3

Metal 1 is not proportional

Choice A

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
