Answer:
609638400
Step-by-step explanation:
Each row must alternate boys and girls, so every row is either BGBGB or GBGBG, where B denotes a boy and G denotes a girl. Since there are 8 girls and 7 boys, the teacher must have two rows of GBGBG and one row of BGBGB. There are three ways to choose this row, and once this is done, every seat is reserved for either a girl or a boy. There are 8! ways to arrange the girls in their seats, and 7! ways to arrange the boys, so the total number of seating arrangements is 3 * 7! * 8!

At a hotel 3/4 of 100 rooms are occupied today yesterday 4/5 of 100 rooms were occupied on which day were more rooms occupied in by how much
Answers
Answer:
Yesterday 4/5 and by 5 more people
Step-by-step explanation:
Ok so 3/4 of 100 is just 100/4*3, which is 75. 4/5 of 100 is 100/5*4, therefore, equaling 80. So 80 > 75, and when you find by how much more you do 80-75, which is 5. I hope this helps and if you have any questions you can comment them on this answer
Answer:
The answer is 4/5
Step-by-step explanation:
well 3/4 of 100 is 75. 4/5 of 100 is 80.
one fourth is equal to 25. We know that because we divide 100/4 and since there's 3 out of 4 (25x3=75)
one fifth is equal to 20. (100/5 = 20) 4 times 20 equals 80

Step-by-step explanation:
Perimeter = 2(15 + 8)
Perimeter = 46
Answer:
46 cm
Step-by-step explanation:
To calculate the perimeter of a rectangle, you have to add the length with itself then add the width with itself. After that, you add both of the sums together to get the answer. For this particular question, this is what you have to do.
1.Add the length with itself 15+15=30
2.Add the width with itself 8+8=16
3. Add both sums 30+16=46
In conclusion, the perimeter of the rectangle is 46 centimeters.

Answers
Answer:
It equals 2900 decigrams
Step-by-step explanation:
29 dekagrams = 290 grams
290 grams = 2900 decigrams
Therefore, 29 dekagrams = 2900 decigrams
The equivalent weight in grams for a given weight in dekagrams is approximately 10 times the weight in dekagrams.
To find the equivalent weight in grams for a given weight in dekagrams, you can use the conversion factor that 1 dekagram (dag) is equal to 10 grams.
Given the information that 29 dekagrams equals 290 grams, you can set up a proportion:
[tex]\(\frac{29 \text{ dag}}{290 \text{ g}} = \frac{1 \text{ dag}}{x \text{ g}}\)[/tex]
Cross-multiplying:
[tex]\(29x = 290 \times 1\)[/tex]
Solving for x:
[tex]\(x = \frac{290}{29}\)\\\\\(x \approx 10\)[/tex]
Therefore, the equivalent weight in grams for a given weight in dekagrams is approximately 10 times the given weight in dekagrams.

Answer:
1.06 m²
Step-by-step explanation:
To find the area of the two ends, you need to find the area of the inner circle, then subtract that from the area of the large circle.
As we know, A = πr²
The diameter of the larger circle is 1.8, so the radius is 0.9.
π(0.9)² = 2.54
The diameter of the smaller circle is 1.6, so the radius is 0.8
π(0.8)² = 2.01
2.54 - 2.01 = 0.53 m² (this is for one end)
0.53 x 2 = 1.06 m²

Answer:
10 inches.
Step-by-step explanation:
Assuming that before Monday, there was no snow.
On Monday, it snowed 8 inches, which is a net positive of 8:
0 + 8 = 8in total.
On Tuesday, it melted 3 inches, which is a net negative of 3:
8 - 3 = 5in total.
On Wednsday, it snowed another 5 inches, which is a net positive of 5:
5 + 5 = 10in total.
10 inches total of snow was on the ground on Wednesday.

x = 13, y = 24.
Step-by-step explanation:
5x - 8 + 63 + 7x - 31 = 180 (interior alternate angles are equal).
12x + 24 = 180
12x = 180 - 24 = 156
x = 156/12
x = 13.
4y + 27 = 63 + 7x - 31 (interior alternate angles are equal).
4y +27 = 32 +7(13)
4y = -27 +32 + 91
4y = `96
y = 96/4
y = 24.
