Answer:
4 balloons for each balloon animal.
Step-by-step explanation:
Amira sells balloon animals. The given table compares the number of balloon animals sold and the remaining number of balloons on a certain day.
Animals Balloons
15 200
24 164
33 128
When she sold 15 animals the leftover balloons were 200.
then she sold 24 animals the number of leftover balloons were 164.
The difference of the number of items = 24 - 15 = 9 more animals sold
The difference of the leftover balloons = 200 - 164 = 36 balloons used
Now the number of her sold animals was = 33
and the left over balloons = 128
The number of sale was increased by 24 to 33 = 33 - 24 = 9 more animals
and the leftover balloons now 164 to 128 = 164 - 128 = 36 used
Therefore, we can see each sale of 9 balloon animals she used 36 balloons.
so Amira used for each balloon animal =
= 4 balloons.
Amira used 4 balloons for each balloon animal.
Answer:
Step-by-step explanation:
Given
6 rolls of a die;
Required
Determine the possible sequence of rolls
From the question, we understand that there were three possible outcomes when the die was rolled;
The outcomes are either of the following faces: 1, 2 and 3
Total Number of rolls = 6
Possible number of outcomes = 3
The possible sequence of rolls is then calculated by dividing the factorial of the above parameters as follows;
Hence, there are 120 possible sequence.
Note necessary facts about isosceles triangle ABC:
1. Consider right triangle ACD. The adjacent angle to the leg AD is 30°, so the hypotenuse AC is twice the opposite leg CD to the angle A.
AC=2CD.
2. Consider right triangle BCD. The adjacent angle to the leg BD is 30°, so the hypotenuse BC is twice the opposite leg CD to the angle B.
BC=2CD.
3. Find the perimeters of triangles ACD, BCD and ABC:
4. If sum of the perimeters of △ACD and △BCD is 20 cm more than the perimeter of △ABC, then
5. Since AC=BC=2CD, then the legs AC and BC of isosceles triangles have length 20 cm.
Answer: 20 cm.
