Hi! C and D are not the answers, because they do fall downward and with the force of gravity. It does fall with an acceleration of -10 m/s. The object actually falls faster as it gets closer to ground and above 10 m/s, so the speed is not constant. The answer is A.
First, let's declare some variables.
x = # of sticker packs
y = total # of stickers
Now, let's create an equation to model the problem.
y = 21x + 8
Let's plug in 50 for y and solve for x.
50 = 21x + 8
Subtract 8 from both sides.
42 = 21x
Divide both sides by 21
2 = x
Anthony will have to buy 2 sticker packs to have a total of 50 stickers.
Hello,
your answer should be true if you put parenthesis!
=1/2[log base 9(57)-log base9 (74)]
=1/2 log base 9 (57)-1/2 log base 9(74)
Answer:
72
Step-by-step explanation:
for the rectangles you use the formula :
a=lw 3x6=18x2=36 + 4x6=24
and for the triangles you use:
a=1/2bh 3x4=12/2 + 3x4=12/2
then you add it all together
36+24+12=72
