The length and a quarter of the width of a rectangle add up to 7 in, while the length and the width add up to 10 in. What are the rectangle's length and width?

Answers

The length of rectangle is 6 inches and width is 4 inches.

Step-by-step explanation:

Let,

l be the length of rectangle

w be the width of rectangle.

Quarter means $(1)/(4)$ .

According to given statement;

$l+(1)/(4)w=7\nl+0.25w=7\ \ \ Eqn\ 1$

l+w = 10 Eqn 2

Subtracting Eqn 1 from Eqn 2

$(l+w)-(l+0.25w)=10-7\nl+w-l-0.25w=3\n0.75w=3$

Dividing both sides by 0.75

$(0.75w)/(0.075)=(3)/(0.75)\nw=4$

Putting w=4 in Eqn 2

$l+4=10\nl=10-4\nl=6$

The length of rectangle is 6 inches and width is 4 inches.

Of the following numbers which one is prime 14 13 21 33

Answers

Answer:

13 is the prime number

Step-by-step explanation:

You must take into account that a prime number is one that is just divisible by 1 and itself. So, let's analyse each number.

Number 14

If you divide 14 by 1 you obtain 14.

If you divide 14 by 14 you obtain 1.

If you divide 14 by 2 you obtain 7.

If you divide 14 by 7 you obtain 2.

14 is not prime because is divisible by 1, 2, 7, and 14

Number 13

If you divide 13 by 1 you obtain 13.

If you divide 13 by 13 you obtain 1.

13 is a prime number because it can't be divided by other number, just 1 and itself

Number 21

If you divide 21 by 1 you obtain 21.

If you divide 21 by 21 you obtain 1.

If you divide 21 by 3 you obtain 7.

If you divide 21 by 7 you obtain 3.

21 is not prime because is divisible by 1, 3, 7, and 21

Number 33

If you divide 33 by 1 you obtain 33.

If you divide 33 by 33 you obtain 1.

If you divide 33 by 3 you obtain 11.

If you divide 33 by 11 you obtain 3.

33 is not prime because is divisible by 1, 3, 11, and 33

Thus, 13 is the prime number

A prime number is a number which is only divisible by itself and 1.
No even numbers can be primes because they are all divisible by 2.
Therefore, 14 is not a prime number.
21 ÷ 3 = 7
33 ÷ 3 = 11
That leaves 13.

13 is a prime number.

a square patio has an area of 225m2. the owner wants to put lights around the patio each string of lights is 25m long. how many strings of lights are needed?

Answers

ok....so look at the attached picture

Final answer:

To find the number of strings of lights needed for the square patio, divide the perimeter of the square by the length of each string of lights. Round up to the nearest whole number.

Explanation:

To find the number of strings of lights needed, we need to divide the perimeter of the square patio by the length of each string of lights. Since the patio is a square, all sides are equal in length. To find the side length, we can take the square root of the area.

In this case, the area is 225m², so the side length of the square patio is √225m = 15m. The perimeter of the square is 4 times the side length, which is 4 × 15m = 60m. Dividing the perimeter by the length of each string of lights, we get 60m ÷ 25m = 2.4. Since we can't have a fraction of a string of lights, we round up to the nearest whole number. Therefore, 3 strings of lights are needed.

A restaurant requires 4 1/2 ounces of butter for every bowl of curry it makes. In an hour an average of 2 1/2 bowls of curry is served.How many ounces of butter are required in 1 1/2 hours?

ounces

Enter a number like 212or 52.

Answers

1 Ounce of Butter = B

Bowl of Curry = C

1 Hour = H

----------------

A restaurant requires 4 + 1/2 ounces of butter for every bowl of curry it makes...

C = 9/2 * B

In an hour, an average of 2 + 1/2 bowls of curry is served...

H = 5/2 * C

... Which means that: H = 5/2 * 9/2 * B

... So: H = 45/4 * B

The question was: How many ounces of butter are required in 1 + 1/2 hours?

Here is the answer:

3/2 * H = 3/2 * 45/4 * B

3/2 * H = 135/8 * B

In words, 16 + 7/8 ounces of butter would be required over a period of 1 + 1/2 hours.
