The school hall is 4 times as long as it is wide. If the perimeter is 55m, what is the length? and what is the width?

Answers

Answer 1

Answer: -- The width of the school is ' W '. We don't know what that is yet,
but we're going to find out.

-- We're told that the length is 4 times as much. So the length is ' 4 W '.

-- Perimeter is (2 widths) + (2 lengths).

2 widths = 2 W
2 lengths = 8 W
Perimeter = 10 W

-- We're also told that the perimeter is 55m. That's just what we need.

10 W = 55 m

Divide each side of this equation by 10:

W = 5.5 m

There's the width !
The length of the hall is 4 times as much.

Length = 4 W = 22 m

Write the denominator of the fractiona 7/20 as the product of prime factors

Answers

Answer:

Step-by-step explanation:

prime factors of 20 = 2 * 2 * 5

$(7)/(20)=(7)/(2*2*5)$

Final answer:

The denominator of the fraction 7/20 can be written as the product of prime factors: 2 x 2 x 5.

Explanation:

The denominator of the fraction 7/20 can be written as the product of prime factors by finding the prime factorization of 20.

Start by dividing 20 by the smallest prime number, which is 2. 20/2 = 10.
2 is a prime factor, so we continue to divide 10 by 2. 10/2 = 5.
5 is a prime number, so we have found the prime factorization of 20: 2 x 2 x 5 = 20.

Therefore, the denominator of the fraction 7/20 can be written as 2 x 2 x 5.

why does y=mx+b ?

Answers

Answer:

The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept

Mike wants to make meatloaf. His recipe uses 7lbs of meat. If he uses a 3 to 1 ratio of beef to pork, how much pork will je use? enter your answer as a mixed number in simplest terms

Answers

The total quantity of meatloaf that Mike uses for his recipe = 7 pounds
The ratio of beef to pork that needs to be used = 3:1
Let us assume the common ratio to be = x
Then
3x + x = 7
4x = 7
x = 7/4
So
The amount of pork that is
needed for the recipe of Mike = 1 * (7/4) pounds
   = (7/4) pounds
   = 1 3/4 pounds
So the quantity of pork that is required to make the recipe of Mike is 1 3/4 pounds. I hope the procedure is simple enough for you to understand.
