Answer:
She has 16 brownies
Step-by-step explanation:
Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.
Answer:
S={1, 1, 2, 2, 3, 4}
Probability of spinning a 1 = 1 in 3 or 33%
Step-by-step explanation:
The sample space is the set of all possible outcomes in an experiment. The outcomes here are the numbers in each section of the spinner: 1, 1, 2, 2, 3, 4. The sample space is:
S={1, 1, 2, 2, 3, 4}
Two out of six possible outcomes are "1s", therefore the probability of spinnin a 1 is:
The probability of spinning a 1 is 1 in 3 or 33%.
Answer:
Yes, the zoo needs to order more fencing. The zoo has 54 ft of fence remaining for the unknown side.
If the unknown side is assumed to have this length, sin (θ) = 1.2857. which is not possible, so the triangle cannot be formed.
Step-by-step explanation:
Let a be the length of the third side of the triangle.
a = 127 - 73 = 54 ft
Let the angle that a makes with the barn be θ
The diagram of this question is attached to this solution.
Using the sine rule, we can examine if the remaining fencing material would be enough by checking if (sin θ) is realistic.
Using sine rule,
[a/(sin 72°)] = [73/(sin θ)]
[54/sin 72°] = [73/sin θ]
sin θ = (73 × sin 72°)/54 = 1.2857
sin θ = 1.2857
This is obviously not a realistic value for sin θ since it is known that sin θ ranges between 0 and 1.
The 54 ft is obviously not enough.
Hence, the zoo needs more fencing material to be able to complete the outdoor triangular giraffe exhibit.
Hope this Helps!!!
