What is the equation has intercepts at x(1, 0, 0), y(0, -1,0), and z(0, 0, 2)
bulgar [2K]

In intercept form, the plane that has these intercepts is ...

... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1

... x/1 + y/(-1) + z/2 = 1

... 2x -2y +z = 2 . . . . . in standard form

I tried many times to solve this question: Joy makes 6,5 litres soup correct to the nearest 0.5 litres. She serves the soup in 2
Paraphin [41]

Joy makes 6.5 litres soup correct to the nearest 0.5 litres. She serves the soup in 280ml portions correct to the nearest 10ml. 22 people order this soup. Does joy definitely has enough soup to serve the 22 people.

Answer:

Yes, Joy definitely does has enough soup

Step-by-step explanation:

From the question, we know,

Joy make 6.5 litres of soup

Serves it in 280ml portions

Step 1

We convert the portions to liters

1 ml = 0.001 litre

280 ml

= 280ml × 0.001 litre/1 ml

= 0.28litre

Step 2

We divide 6.5 liters by 0.28 to find out how many people can be served

= 6.5 ÷ 0.28

= 23.2142857143 people

We can see that 6.5 liters soup can serve 23 people approximately.

Therefore, Yes, Joy definitely does has enough soup to serve 22 people

1. Find the Least Common Denominator (LCD) of \frac{2}{5} , \frac{1}{2}
Method 1: By Listing Multiples<span>List out all multiples of each denominator, and find the first common one.

5: 5,10
2: 2, 4, 6, 8,10</span>

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.

5 : 5
2 : 2
Therefore, the LCD is 2 x 5 = 10
 2. Make the denominators the same as the LCD

\frac{2 * 2}{5 * 2} + \frac{1 * 5}{2 * 5}

3. Simplify. Denominators are now the same

\frac{4}{10} + \frac{5}{10}

4. Join the denominators

\frac{4+5}{10}

5. <span>Simplify

</span>\frac{9}{10}

<span>Done (Fact: Decimal Form 0.9)</span>
