There are 5 people in the family.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that each member of angela's family drank an 8-ounce mixture of coffee with milk.  

Let the number of people would be n.

And a represents the coffee, and  b represents the milk,

One-quarter of the milk and one-sixth of the coffee was consumed by Angela.

⇒ Angela drank b/4 of milk and a/6 of coffee.

Since everyone drank the same amount of coffee,

We have been to create an equation as

⇒ (a/6 + b/4)p = a + b

⇒ 2a(6 - n) = 3b(n - 4)

Given that both a and b are positive, we must fulfill the condition.

⇒(6 - n) > 0 and (n - 4) > 0

⇒ 6 > n and n > 4

So, the correct number of people = 5.

Hence, there are 5 people in the family.

Answer:

[tex]\frac{211}{500}[/tex]

Step-by-step explanation:

[tex].4\bar{2}[/tex]  means the 2 repeats till infinity
[tex].4\bar{2}[/tex]  = .4222222222.....

To convert to fraction just take the first three decimal place digits 422 and divide by 1000 to convert to fraction

[tex].4\bar{2} = \frac{422}{1000}[/tex]

Dividing numerator and denominator of this fraction by 2 gives
[tex]\frac{422/2}{1000/2} =\frac{211}{500}[/tex]

This cannot be simplified further and therefore
[tex].4\bar{2} = \frac{211}{500}[/tex]

If we had chosen first 4 decimal digits then it would be[tex].4\bar{2} = \frac{4222}{10000} = \frac{2111}{5000}[/tex]
i.e. we divide by 10,000

Answer:

y = -4/3x + 2

Step-by-step explanation:

Point slope form is this:

y - y1 = m (x - x1)

Where m is the slope. y1 and x1 are where you put your coordinates.

so now we just plug it in.

y - (-2) = -4/3 (x - 3)

We should clean it up in order to make it look like this equation:  y = mx + b

y + 2 = -4/3x -4/3(-3)

y + 2 = -4/3x + 4

y = -4/3x + 2

The reciprocal of 150 will be 1/150.

We have a marine center has 150 parking spaces in front of its building.

We have to find the reciprocal of 150.

The reciprocal of a number is a number such that the product of both the numbers is equal to 1. Mathematically, if the original number is a, then its reciprocal will be 1/a , such that -

a x 1/a = 1

According to the question -

Let us assume that  A = 150

Now, from the definition of reciprocal, the reciprocal of A will be -

1/A. Therefore, the reciprocal of 150 will be = 1/150

Hence, the reciprocal of 150 will be 1/150.

Required;

Initial side length:

The initial side length, given to the nearest tenth, s, is the square root of the area, A, given as follows;

s = √(314 ft.²) ≈ 17.7 ft.

New Side length:

The side was increased by 50%, to give,

314 + 0.5×314 = 471

The new area of the garage = 471 ft.²

The side length of the new garage, s = √(471) ≈ 21.7 ft

The side of the garage now is 21.7 ft.

Percentage increase in length:

The percentage increase is given as follows;

% increase in length

= new side length - old side length / old side length * 100
