The question is asking which of the answer choices is NOT equivalent to
2^-3 = 1/(2^3) = 1/8
You can determine this by expressing each of the answer choices in a manner that lets you compare them to 2^-3 or to 1/8.
A. -2^3 = -8 . . . . . this is not equivalent to 2^-3 or 1/8. This is the appropriate selection.
_____
Let's check the others, just to be sure.
B. 2(1/4)^2 = 2(1/16) = 2/16 = 1/8 . . . . is equivalent to 1/8
C. 2^2 × 2^-5 = 2^(2-5) = 2^-3 . . . . is equivalent to 2^-3
D. (1/2)^3 = 1/2^3 = 1/8 . . . . is equivalent to 1/8
Our choice of A is correct, as all these other choices are equivalent to the given expression.
Answer:
67°
Step-by-step explanation:
Corresponding angles are equal in parallel lines.
Here, ∠acb and ∠aed are corresponding angles for lines bc and de
hence ∠aed = ∠acb = 39
in triangle ade,
x + 74 + 39 = 180 (angle sum property of a triangle)
x = 67°
Step-by-step explanation:
10 minutes = 600 seconds
Seconds per question is seconds/questions
Divide 600 by the number of questions:
600/(number of questions) = ________ seconds per question
Answer:
D) 1
Step-by-step explanation:
using the distributive property we have ax+a+bx-b-2=0. because the equation is true for all real x, ax=-bx. this means a-b-2=0 and a=-b. a-b-2=0 becomes a=b+2. then we substitute a for -b and get -b=b+2 which becomes 2b=-2 so b=-1. since a=-b, a=1
Answer:
yes
Step-by-step explanation:
yes it is because if 6ounces is $2.10 and the more ounces you add the higher the cost
btw just copy/paste :P
