Step-by-step explanation:

Answer:

24 days

Step-by-step explanation:

120 students =30 days

120+30 =150 students

MORE/LESS METHOD

120 students (a) : 30 days(y)

150 students (b) : x

Find the value of x using the formula: a/b × y

If you think the value of x will be more than y then the bigger number will be the numerator. If u think x will be less, then the smaller number will be in the numerator.

I predict that x will be less than y

THEREFORE... 120/150 ×30

= 24 days

Step-by-step explanation:

ans is simple so plz tell me that it is right or wrong and also it is helpful to u or not

Answer:

All you have to do is equal the equations to each other to find x for each problem!

Answer:

[tex]A=11.7\ m^2[/tex]

Step-by-step explanation:

Given that,

Central angle, [tex]\theta=160^{\circ}[/tex]

Diameter,d = 5.8 m

Radius, r = 2.9 m

We need to find the area of sector. The formula for the area of sector is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{160}{360}\times 3.14\times 2.9^2\\\\=11.7\ m^2[/tex]

So, the area of a sector is equal to [tex]11.7\ m^2[/tex].

Answer:

1. $624.86

2. 1.99x

3. 2.6 pounds

Step-by-step explanation:

1. Multiply 1.99 by 314 to get 624.86

2. With the equation 1.99x, you can substitute any variable into it and it will hold true.

3. Divide 5.17 by 1.99, the price, and you get 2.597 pounds, which rounds to 2.6

Answer:

Answer:

x=−8 and y=−4

Step-by-step explanation:

8x−17y=4;−8x+15y=4

add eqn1 and 2

to eliminate x

you will get y=-4

put it zin eqn 1

x=-8

x=100×15/75

x=1500/75

x=20% boys

Answer:

20%

Step-by-step explanation:

look at the formula I have used then you will understand good day

Answer:

(−2)×5<(−20)

Step-by-step explanation:

Evaluating the options given :

(−2)×5<(−20)

Open the bracket

- 10 < - 20 (false) ` This expression isn't true

(−2)×(−5)>(−25)

Open the bracket

10 > - 25 (true)

2×5>(−25)

Open the bracket

10 > - 25 (true)

2×(−5)<20

Open the bracket

- 10 < 20

Answer:

he uses 30 pages

Step-by-step explanation:

turn 10% into a decimal. this would be .10

.10 • 300=30

30 pages

Answer:

9a^4b^10 ( 4 - 9a^12b^20)

Step-by-step explanation:

The greatest common factor of the two terms is 9a^4b^10

You can now remove the greatest common factor outside the brackets.

Inside the brackets, you place the value obtained by dividing 36a^4b^10- 81a^16b^20 by 9a^4b^10

That is = 4 - 9a^12b^20

Please note that the laws of indices i used for the above division is: n^a divided by n^b = n^(a-b)

Now, the factorised answer for your question =  9a^4b^10 ( 4 - 9a^12b^20)

Answer:

hi answer is 69 solved by Pythagoras theorem

Answer:

7.94

Step-by-step explanation:

We can use the Pythagorean theorem for this

since we know two legs, and not the hypotenuse, we should solve for that

the pythagorean theorem states that a squared + b squared is equal to c squared. C, is the hypotenuse, sos let’s plug it in

16 + 47 = c squared

63 = c squared.

square root 63 = c

c is equal to 7. 94 rounded to the nearest hundered

Answer: 90km/hour

Step-by-step explanation:

The formula for speed is given as:

= Distance / Time

where,

Distance = 120km

Time = 80 minutes = 80/60 = 1 1/3 hours

Speed = Distance / Time

= 120 / 1 1/3

= 120 / 4/3

= 120 × 3/4

= 90km/hour

The speed is 90km/hour.

Answer:

A 21/4

Step-by-step explanation:

When forming a perfect square trinomial you need to "complete the square".

All of the steps to completing the square when solving an equation:

1.  The leading coefficient must be 1.  

2.  Divide b by 2.

3.  Square (b/2)

4.  Add (b/2)^2 to both sides to keep the polynomial balanced.

5.  You can now write the perfect square trinomial and solve.

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4

Answer:

Step-by-step explanation:

11 - 6 = 5  ,   16 - 11 = 5  ,  21 - 16 = 5

So, it's atithmetic formula with common difference os 5

[tex]a_n = a_1+d(n-1)\\\\a_1=6\\d=5\\\\a_n=6+5(n-1)\\\\a_n=6 +5n-5\\\\a_n = 5n+1[/tex]
