Answer:
ok
Step-by-step explanation:
it was a different question in our lesson
The two figures are similar because if you take each side length of figure O and multiply it by three, they equal the side lengths of A.
For ABCD
9*L = 162 ft2
L = 18
for WXYZ
18*6=108 ft2
18108 ft2
9514 1404 393
Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.

Answer:
3. 9
4. 5 pounds
5. 5/12 of a pound
Step-by-step explanation:
3. "at least 3/8" means to include that column in the count.
4. 3(1/4) + 4(3/8 ) + 3(1/2) + 2(5/8)
= 3/4 + 12/8 + 3/2 + 10/8 but we need a common denominator. LMK in the comments if you need help with that
= 6/8 + 12/8 + 12/8 + 10/8
= 40/8
= 5 pounds.
5. For the average, we add up all the weights, then divide by the number of kittens. Thankfully, we just added everything up in #4. Since we're going to be dividing 5 by 12, we'll end up with a decimal. But since the whole problem was written in fractions, we'll keep it in fractions.
40/8 divided by 12 kittens
40/8 divided by 12 = 40/8 muliplied by the inverse of 12 which is 1/12
40/8 x 1/12
= 40/96
Our numerator and denominator can be evenly dived by 8, so the fraction is reduced to
= 5/12
