Answer:
- AC is congruent to CE
- BG is congruent to DG
- BH is congruent to DF
Step-by-step explanation:
AC is congruent to CE because of the 2 congruent tick marks.
BG is congruent to DG because of the 1 congruent tick mark for each segment.
BH is congruent to DF because of the 3 congruent tick marks for each segment.
Answer:
d = log 38/log31
d = 1.06
Step-by-step explanation:
31 ^ d = 38
Take log of both sides since the exponential equation have different base (always)
d log 31 = log 38
d = log 38 / log 31
d = 1.58 / 1.491
d = 1.06.
We can actually check to see if this is correct.
Substituting d = 1.06
31^ 1.06 = 38.092
(You see, that's approximately correct)
Keep learning, maths is fun!
Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position
There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C
Multiply those values out: 9*8*7 = 72*7 = 504
There are 504 ways to pick three people from a pool of nine.
Answer: 504
Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer

She paid for the tape $ 9.18</span>
<span>The common denominator of the two fractions is: 8
</span><span>1/4 = (1*2)/(2*4) = 2/82/8 = (1*2)/(1*8) = 2/8
<span>Fractions adjusted to a common denominator1/4 + 2/8 = 2/8 + 2/82/8 + 2/8 = (2+2)/8(2+2)/8 = 4/84/8 = 1/2
The answer is 1/2.
