<u>ANSWER:  </u>

70 students like both nepali and maths.

<u>SOLUTION: </u>

Given,out of 200 students in a class. 150 like math, 120 like nepali.

The number of students who like nepali only is one third of the students who like math .

We need to find how many likes both subjects.

Let, the number of students who like only nepali be x.

Then, x is one-third of students who like maths.

x = \frac{1}{3} \times students who like maths

\begin{array}{l}{x=\frac{1}{3} \times 150} \\\\ {x=\frac{150}{3}} \\\\ {x=50}\end{array}

Now, out of 120 students who like nepali, only 50 students like nepali alone, which means remaining students like both nepali and maths

Students who like both subjects = 120 – 50 = 70.

Hence,70 students like both nepali and maths.

9. D because it fits the description when it is graphed. 
11. D because it has the correct vertex, which is (1.5, 4.75). 
12. f(x)=-4(x-2)²+16 works with the table and provided graph!
13. 0 isn't a zero for f(x), so B is correct (the zeros are 1/2 and 4). 
14. The width is about 3.831. 
15. The answer is B because the equation for a parabola in this form is: 
      f(x) = (x - r₁)(x - r₂)

Every one of these except for 15 was solved using desmos, a graphing calculator. 

Hope this helps!

Make 10 equations for 50,000
Kruka [31]

Answer:

1. 50 * 1,000 = 50,000

2. 49,001 + 999 = 50,000

3. 5 * 10,000 = 50,000

4. 100,000/2 = 50,000

5. 20,000 + 30,000 = 50,000

6. 50,000/1 = 50,000

7. 90,000 - 40,000 = 50,000

8. 10 + 49,990 = 50,000

9. 5,000 * 10 = 50,000

10. 1,000,000/20 = 50,000

400 ml squash is made by mixing 50 ml of cordial with water. what fraction of the drink is water?give your answer in its simples
Tasya [4]

squash = cordial + water

400 ml = 50 ml + x ml

350 ml = x ml

Therefore, 350 ml are water.

350 ml / 400 ml = 0.875 = \frac{350}{400} = \frac{35}{40} = \frac{7}{8}

So the answer is 7 / 8

Kellen bought new fish for her home aquarium. She bought 4 turquoise guppies and 3 sunburst tetra GLO fish and spent a total of
FromTheMoon [43]

Answer: A single turquoise guppy costs $3.69

Step-by-step explanation:

Let us use "x" to represent the amount a single turquoise is sold and use "y" to represent that of the Glo fish.

Since Kellen bought 4 guppies and 3 glo fishes for $41.73:

4x + 3y = 41.73 --------eqn 1

Similarly, Danielle purchased 3 guppies and 5 Glo fish for $56.02:

Therefore 3x + 5y = $56.02 -----eqn2

The 2 equations are;

4x + 3y = 41.73 (eqn 1)

3x + 5y = 56.02 (eqn 2)

We then solve the simultaneous equations using substitution method:

From eqn 1,

4x + 3y = 41.73

4x = 41.73 - 3y

x = (41.73 - 3y)/4

Substitute x for (41.73 - 3y)/4 in eqn2.

3[(41.73 - 3y)/4 + 5y = 56.02

11y + 125.19 = 224.08

11y =98.89

y = 98.89/11

y = $8.99

So, 1 Glo fish costs $8.99

Then, substitute "y" for 8.99 in equation 1

4x + (3×8.99) = 41.73

4x + 26.97 = 41.73

4x = 41.73 - 26.97

4x = 14.76

x = 14.76/4

x = $3.69

Therefore 1 turquoise guppy costs $3.69
