Look at the division problem and choose the correct first step. 138 divided by 6 (A)Multiply 6 and 20 to get 120. (B)Subtract 120 from 138. (C)Divide 6 into 13 and put a 2 in the quotient. (D)Divide 6 into 18 and put a 3 in the quotient.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
