Answer:

The corresponding side in the smaller figure is 9 cm

Step-by-step explanation:

Notice that you can use proportions to solve this problem:

The ratio from large image to smaller is: Larger/smaller = 4/3.

Therefore use this type of proportions to find the length of the corresponding side to 12 cm in the smaller figure:

\frac{4}{3} =\frac{12 \,cm }{smaller} \\smaller\,(\frac{4}{3}) = 12\,cm\\smaller=\frac{3* 12\,cm}{4} \\smaller=\frac{36\,cm}{4} \\smaller=9\,cm

Answer:

9

Step-by-step explanation:

also, you meant smaller not smallet right

4/3=12/x

x=9

Answer:

  the probability is 2/9

Step-by-step explanation:

Assuming the coins are randomly selected, the probability of pulling a dime first is the number of dimes (4) divided by the total number of coins (10).

  p(dime first) = 4/10 = 2/5

Then, having drawn a dime, there are 9 coins left, of which 5 are nickels. The probability of randomly choosing a nickel is 5/9.

The joint probability of these two events occurring sequentially is the product of their probabilities:

  p(dime then nickel) = (2/5)×(5/9) = 2/9

_____

<em>Alternate solution</em>

You can go at this another way. You can list all the pairs of coins that can be drawn. There are 90 of them: 10 first coins and, for each of those, 9 coins that can be chosen second. Of these 90 possibilities, there are 4 dimes that can be chosen first, and 5 nickels that can be chosen second, for a total of 20 possible dime-nickel choices out of the 90 total possible outcomes.

  p(dime/nickel) = 20/90 = 2/9

A coin is tossed and a standard number cube is rolled. What is the probability that the coin shows head and the number cube show
krok68 [10]

The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head ---> (1,2,3,4,5,6) & tail ---> (1,2,3,4,5,6)}. so the probability is 3/12= 1/4.


C: 1/4

Helpppppppppppppppppp!

Remember that the radicand (the area under the root sign) must be positive or zero for a radical with an even index (like the square root or fourth root, for example). This is because two numbers squared or to the fourth power, etc. cannot be negative, so there are no real solutions when the radicand is negative. We must restrict the domain of the square-root function.

If the domain has already been restricted to x \geq -11, we can work backwards to add 11 to both sides. We see that x+11 must be under the radicand, so the answer is A.

PEMDAS is what your gonna use to solve this you go from right to left

First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one 
70 this is your answer i hope
