The length of a rectangle is 15 cm and the width is 8 cm which is the perimeter of the rectangle

Answers

Answer:

46

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.

Step-by-step explanation:

Answer:

Option B is correct

The number of real number solutions for the given equation is, 1.

Step-by-step explanation:

Given the equation:  

Since, this is a quadratic equation of the form of  

where a =1 , b = -10 and c =25.

The discriminant of a quadratic equation is,  

then;

Discriminant =  = (100-100) = 0

Since, a  discriminant of zero means there is only one real solution for x.

Substitute the given values.

Simplify:

x = 5

Therefore, the number of real solution for the given equation is, 1

29 dekagrams equals 2900 what

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.

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

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
