Responder:
20.000
Explicação passo a passo:
Dado que:
Porcentagem de bois no rebanho = 15%
Percentagem de vacas = (100 - 15)% = 85%
Número de vacas = 17.000
Por isso,
85% = 17.000
15% = x
Multiplicação cruzada
0,85x = 17.000 * 0,15
0,85x = 2550
x = 2550 / 0,85
x = 3000
Número de bois no rebanho = 3000
Portanto, número total de gado no rebanho =
3000 + 17000 = 20.000

120 students of a hostel food enough for 60 days. if 30 more students joined after 15 days. how long will the remaining food last.
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

Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
A. 2 1/4
B. 1 1/2
C. 4 1/2
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:
(−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:
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)

Apples cost $1.99 per pound. How much do 314 pounds of apples cost? $ How much do x pounds of apples cost? $ Clare spent $5.17 on apples. How many pounds of apples did Clare buy? pounds
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

Matteo is working two jobs, making $15 per hour at the movie theater and $18 per hour washing cars. Last week Matteo worked a total of 30 hours and earned a total of $480. Determine the amount of hours Matteo worked at the movie theater and the cash wash.
Answer:
movie theatre = 20 hours
car wash = 10 hours
Step-by-step explanation:
this would be solved using simultaneous equation
let a = hours worked in theatre
b = hours spent wash cars
15a + 18b = 480 eqn 1
a + b = 30 eqn 2
multiply eqn 2 by 15
15a + 15b = 450 eqn 3
subtract 1 from 3
3b = 30
b = 10 hours
substitute for b in eqn 2
a + 10 = 30
a = 20 hours
What is the area of sector with a central angle of 160 and a diameter of 5.8 m? Round the answer to the nearest tenth.
A) 8.1 m^2
B) 4.0 m^2
C) 46.0 m^2
D) 11.7 m^2
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].
