Remember that all of the angles on one side of a straight line
add up to 180 degrees.
Here's how to use that factoid to set it up:
The two angles on the same side of the slanted line add up to 180.
(5k + 20) + (3k + 16) = 180 .
Solve that for 'k'. Then ... Both angles on the right side of
the vertical line also add up to 180. So the answer to the
question is
[ 180 - (3k + 16) ].
Just folding my arms and sitting back and looking at all of that,
I got 110 degrees. Do NOT use that for the answer, but I'll be
curious to see if it's anywhere close.
Find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.
Tatiana [17]
Solution:
we have been asked to find the number of distinguishable permutations of the letters m, i, s, s, i, s, s, i, p, p, i.
Here we can see
m appears 1 time.
i appears 4 times.
S appears 4 times.
p appears 2 times.
Total number of letters are 11.
we will divide the permutation of total number of letters by the permutation of the number of each kind of letters.
The number of distinguishable permutations
Hence the number of distinguishable permutations
Answer:
C
Step-by-step explanation:
note that (f - g)(x) = f(x) - g(x)
f(x) - g(x)
= 10x + 7 - (x² - 7x) ← distribute parenthesis by - 1
= 10x + 7 - x² + 7x ← collect like terms
= - x² + 17x + 7 → C
Answer:
16 tiles
Step-by-step explanation:
Divide the length of the wall by the width of one tile.
4 / 1/4 = 4/1 * 4/1 = 16/1 = 16
Answer: 16 tiles
