Answer:
6 different groups of toy animals
Step-by-step explanation:
In this question, we are to calculate the number of different groups of toy animals Michael can take.
Since we are selecting, this is clearly a COMBINATION question. Now from the question, we are trying to select 5 toy animals from a group of 6 different animals to fit in the bag
The number of ways we can do this is 6C5 ways
Mathematically, if we have to select a number of r items from a group of n items, the number of ways this can be done is;
nCr = n!/(n-r)!r!
Using the case in the question, we have; 6!/5!(6-5)! = 6!/5!1! = 720/120 = 6 groups
Answer:
6 different groups of toy animals
Step-by-step explanation:
The question above can be solved by applying the Combination technique
Combination technique uses the formula:
nCk = n! /k!(n-k)!
Where in the question above:
n = 6
k = 5
Therefore we have , 6C5
= 6! / 5! (6-5)!
= 6!/ 5!(1!)
6! = 6×5×4×3×2×1
5! = 5×4×3×2×1
Hence,
= (6×5×4×3×2×1) / (5×4×3×2×1)(1)
= 6
Hence, Michael can take 6 different groups of toy animals with him on his vacation.

Find the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
[tex]201 cm^2[/tex]
Step-by-step explanation:
The circumference of a circle is given by:
[tex]c=2\pi r[/tex]
where
r is the radius of the circle
For the circle in this problem,
c = 50.24 cm
Therefore the radius is:
[tex]r=\frac{c}{2\pi}=\frac{50.24}{2\pi}=8 cm[/tex]
The area of a circle is given by the formula
[tex]A=\pi r^2[/tex]
where r is the radius.
For the circle in this problem,
r = 8 cm
So the area is
[tex]A=\pi \cdot 8^2 = 201 cm^2[/tex]
The area of the circle is 201 cm square.
Calculation of the area of the circle:Since we know that
Circumference of the circle = [tex]2\pi r[/tex]
So here radius should be
[tex]= c\div 2\pi \\\\= 50.24\div 2\pi[/tex]
= 8 cm
Now the area of the circle is
[tex]= \pi r^2\\\\= 3.14\times 8^2[/tex]
= 201
Hence, we can conclude that The area of the circle is 201 cm square.

Impossible Puzzles will have more downloads than Jigsaw Junction in 1 day.
Explanation:To find out how many days it will take for Impossible Puzzles to have more downloads than Jigsaw Junction, we need to set up an equation and solve for the number of days.
Let's assume that the number of downloads for Impossible Puzzles on the first day is x. Since it doubles in total number of downloads each day, the number of downloads on the second day would be 2x, on the third day would be 4x, and so on.
On the other hand, Jigsaw Junction is downloaded 10,000 times each day after the first day. So, for n number of days, the number of downloads for Jigsaw Junction would be [tex]10,000 * n.[/tex]
We want to find the number of days when the number of downloads for Impossible Puzzles is greater than the number of downloads for Jigsaw Junction. So, we can set up the equation [tex]4x > 10,000n.[/tex]
To find the value of x, we can substitute 2,000 (the number of downloads on the first day for Impossible Puzzles) into the equation: [tex]4(2000) > 10,000n.[/tex]
Putting all the information together, we can set up the equation [tex]8,000 > 10,000n.[/tex]
To solve for n, we can divide both sides of the equation by[tex]10,000: 8,000/10,000 > n[/tex]. This simplifies to 0.8 > n.
Since n represents the number of days, we round up to the nearest whole number. Therefore, it will take 1 day for Impossible Puzzles to have more downloads than Jigsaw Junction.

Cecil recivies $15 per week for complting chores. He spend $12 on a video game. What percent of his monthly allowence did cecil spend on teh video gmae
Final answer:
Cecil spent 20% of his monthly allowance on the video game, calculated by dividing the $12 spent on the game by his $60 monthly allowance and then multiplying by 100 to get the percentage.
Explanation:
To find out what percent of his monthly allowance Cecil spent on the video game, we first need to calculate his total monthly allowance. Cecil receives $15 per week for completing chores. There are typically 4 weeks in a month, so Cecil's monthly allowance is 15 dollars/week * 4 weeks/month = $60 per month.
Next, we will calculate the percentage of his allowance that was spent on the video game. Cecil spent $12 on a video game. To find this percentage, we use the formula:
Percentage spent = (Amount spent / Total allowance) * 100
Percentage spent = ($12 / $60) * 100
Percentage spent = 0.2 * 100
Percentage spent = 20%.
Therefore, Cecil spent 20% of his monthly allowance on the video game.

Answer:
5. 25/36
6. 25/36
7. -3/4 or 6
8. 0 or 4
Step-by-step explanation:
5. Square both sides: x + 4 = 9 - 6[tex]\sqrt{x}[/tex] + x
Subtract x from both sides and subtract 9 from both sides:
-5 = -6[tex]\sqrt{x}[/tex]
Square both sides again: 25 = 36x
Divide both sides by 36: x = 25/36
6. Square both sides: x + 4 = 9 + 6[tex]\sqrt{x}[/tex] + x
Subtract x and 9 from both sides: -5 = 6[tex]\sqrt{x}[/tex]
Square both sides: 25 = 36x
Divide both sides by 36: x = 25/36
7. Square both sides: x + 3 = 5x + 6 - 6[tex]\sqrt{5x+6}[/tex] + 9
Add 6[tex]\sqrt{5x+6}[/tex] to both sides and isolate it: 6[tex]\sqrt{5x+6}[/tex] = 4x + 12
Divide both sides by 2 and then square both sides again:
3[tex]\sqrt{5x+6}[/tex] = 2x + 6
9 * (5x + 6) = 4x^2 + 24x + 36
45x + 54 = 4x^2 + 24x + 36
4x^2 - 21x - 18 = 0
Factorize: (4x + 3)(x - 6) = 0 ⇒ x = -3/4 or x = 6
8. Square both sides: 2x + 1 = x^2 - 2x + 1
Move all the terms to one side and combine like terms: x^2 - 4x = 0
Factorize: x(x - 4) = 0 ⇒ x = 0 or x = 4
Hope this helps!
Answer:
5. x = 25/36
6. No real solutions
7. x = 6
8. x = 4
Step-by-step explanation:
5. sqrt(x + 4) = 3 - sqrt(x)
Square both sides
x + 4 = 9 - 6sqrt(x) + x
6sqrt(x) = 5
sqrt(x) = 5/6
x = 25/36
6. sqrt(x + 4) = 3 + sqr(x)
x + 4 = 9 + 6sqrt(x) + x
6sqrt(x) = -5
sqrt(x) = -5/6
Not possible. A + square root can not be negative
7. sqrt(x + 3) + 3 = sqrt(5x + 6)
Square both sides
x + 3 + 6sqrt(x + 3) + 9 = 5x + 6
6sqrt(x + 3) = 4x - 6
3sqrt(x + 3) = 2x - 3
Square both sides
9(x + 3) = 4x² - 12x + 9
4x² - 21x - 18 = 0
Using quadratic formula:
x = [21 +/- sqrt(21² - 4(4)(-18)]/(2×4)
x = [21 +/- 27]/8
x = 6, -¾
x = -¾ is rejected because it doesn't satisfy the initial equation
8. sqrt(2x + 1) = x - 1
2x + 1 = (x - 1)²
2x + 1 = x² - 2x + 1
x² - 4x = 0
x(x - 4) = 0
x = 0, 4
0 is rejected because it doesn't satisfy the initial equation

Use what you have learned about triangles and angles to write an equation that represents each situation. Then find each of the missing angles in the triangles below.
9-19.
Additional Challenge: Use what you know about triangles and angle relationships to find the missing angles in the triangles below.
Answers and Step-by-step explanations:
9-18.
a) All the angles of a triangle add up to 180, by definition. So, we can write the expression: 30 + 115 + x = 180.
Then, we can just solve for x by subtracting 30 and 115 from both sides:
x = 180 - 115 - 30 = 35 degrees
b) Again all three angles should add up to 180, so:
x + x + x = 180 ⇒ 3x = 180 ⇒ x = 180/3 = 60 degrees
9-19.
a) These angles add up to 180:
2x + x + 30 = 180 ⇒ 3x + 30 = 180 ⇒ 3x = 150 ⇒ x = 50
2x = 50 * 2 = 100
The missing angles are 100 degrees and 50 degrees.
b) Again, these add up to 180:
x + 10 + x + 90 = 180 ⇒ 2x + 100 = 180 ⇒ 2x = 80 ⇒ x = 40
x + 10 = 40 + 10 = 50
The missing angles are 50 degrees and 40 degrees.
Hope this helps!
Answer:
9-18
a)
x = 180 - (115 + 30) = 180 - 145 = 35°
b)
3x = 180 => x = 180 : 3 => x = 60°
9-19
a)
180 = x + 2x + 30
180 - 30 = 3x
3x = 150
x = 50°
b)
180 = x + 10 + x + 90
180 - 10 - 90 = 2x
2x = 80
x = 40°

A photo of an ant in a science book is increased 515% as large as the actual size. If the ant is 16 millimeters, what is the size of the ant in the photo
Answer:
82.4 millimeters is the size of the ant in the photo
Step-by-step explanation:
In this question, we are asked to calculate the size of an ant in a science book given the actual size of the ant and the percentage increase is the size of the ant in the book.
From the question, we can identify that the actual size is 16 millimeters
Now let’s find 515% of this to know the size to which it would be magnified in the science book.
That would be;
515/100 * 16 = 82.4 millimeters
Hence, this means the ant will have a size of 82.4 millimeters in the science book
Answer:
The size of the ant in the photo is 88 mm
Step-by-step explanation:
Here, we have the percentage increase = 515 %
Size of ant = 16 millimeters in real life,
Therefore, the size of the ant in the in the photo, is given by,
[tex]\frac{16 \, mm}{100} = \frac{y\, mm}{550} = \frac{16 \times 550}{100} = \frac{y \times 100 \, mm}{100} \rightarrow 88 \, mm = y[/tex]
y = 88 mm
The size of the ant in the photo = 88 mm.
If six people decide to come to a basketball game, but three of them are only 2/5 sure that they will stay for the entire time (the other three are sure they'll stay the whole time), what is the probability that at the end, at least 5 people stayed the entire time
Answer:
the probability that at the end, at least 5 people stayed the entire time = 0.352
Step-by-step explanation:
From the question, 3 of the people are sure to stay the whole time. So, we'll deduct 3 from 6.which leaves us with 3 that are only 2/5 or 0.4 sure that they will stay the whole time.
Thus, what we need to compute to fulfill the probability that at the end, at least 5 people stayed the entire time of which we know 3 will stay, so for the remaining 3,we'll compute;
P[≥2] which is x~bin(3,0.4)
Thus;
P(≥2) = (C(3,2) x 0.4² x 0.6) + (C(3,3) x 0.4³)
P(≥2) = 0.288 + 0.064
P(≥2) = 0.352

// Use the y value to solve for x
x = (5/6)(3)+9/2 = 7
Solution :
{x,y} = {7,3}
