Answer:
96 tiles
Step-by-step explanation:
The number of tiles measured 14 cm and 9 cm that will fit into a rectangular
region whose length and breadth are 168 cm and 72 cm may be computed as a ratio of the areas of the two rectangles.
Hence number of tiles
= 168 * 72/14 * 9
= 12 * 8
= 96 tiles
x:14 = 7:8
x:14 = x/14
7:8 = 7/8
x/14 = 7/8
Multiply the numerator of the 1st ratio with the denominator of the 2nd.
And multiply the numerator of the 2nd ratio with the denominator of the 1st.
Doing so, we get -
x * 8 = 7 * 14
So, 8x = 7 * 14
8x = 98
We divide 98 by 8 (transposition method)
x = 98/8
Therefore, x = 12.25
Your answer is:
60= 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
96= 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The second-highest number of factors are 48 and 80, containing 10 factors each.
P(spades) = 7/10
there are 10 different cards that can be picked, out of which what we want to pick is spades which are 7. and so there are 7 chances that we will get to pick spades out of all the 10 possibilities. hope it is easy to understand
