The total number of students in rolled at Berkmar middle school is 1400 students the ratio of boys to girls is 3 to 4 for the sc
Anna [14]

Given:

Total number of students = 1400

The ratio of boys to girls is 3 to 4 for the school.

To find:

The number of boys and girls.

Solution:

We have,  Boy : Girls = 3:4.

Let number of boys be 3x and number of girls be 4x.

Total number of students = 1400

3x+4x=1400

7x=1400

Divide both sides by 7.

x=200

Now,

Number of boys =3\times 200=600

Number of girls =4\times 200=800

Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.

A real estate agent sold a lot for P550,000.00. If his agency pays 10% commission, how much commission will he/she receive?​
Elina [12.6K]

Answer:

  P55,000

Step-by-step explanation:

The amount of commission is found by multiplying the commission rate by the value of the sale(s).

  commission = rate × sales

  commission = 0.10 × p550,000 = P55,000

The agent will receive P55,000 in commission.

_____

<em>Check</em>

The amount of commission cannot be more than the value of the sale. It is generally a small fraction of the sale value. Here, it is 1/10.

angle A and angle B are complementary, that is their measurements add up to 90. Angle B measures 32 more than angle A. what are
dmitriy555 [2]

<em>Complementary= 90 Degrees </em>

<em>Equation: x + x = 90 </em>

A = x

B = x + 32

<em>2x = 90 - 32 </em>

<em>2x = 58 </em>

<em>x = 29 </em>

<em>Angle A = 29 degrees </em>

<em>Angle B = 61 degrees.</em>

consider a polynomial f(x)=ax^3 + bx^2 + x + 2/3.if x + 3 is a factor of f(x) and f(x) is divided by x + 2, then we get remainde
Elanso [62]

Answer:

a = 2/27

b = 13/27

Step-by-step explanation:

The given polynomial is presented as follows;

f(x) = a·x³ + b·x² + x + 2/3

Given that x + 3 is a factor, we have;

f(-3) = 0 = a·(-3)³ + b·(-3)² - 3 +2/3 = 0

-27·a + 9·b - 3 + 2/3 = 0

-27·a + 9·b = 7/3........(1)

Also we have

(a·x³ + b·x² + x + 2/3) ÷ (x + 2) the remainder = 5

Therefore;

a·(-2)³ + b·(-2)² + (-2) + 2/3 = 5

-8·a + 4·b - 2 + 2/3 = 5

-8·a + 4·b = 2 - 2/3 = 4/3........(2)

Multiplying equation (1) by 4/9 and subtracting it from equation (2), we have;

-8·a + 4·b - 4/9×(-27·a + 9·b) = 4/3 - 4/9 × 7/3

-8·a + 12·a = 8/27

4·a = 8/27

a = 2/27 ≈ 0.0741

imputing the a value in equation (1) gives;

-27×2/27 + 9·b = 7/3

-2 + 9·b = 7/3

9·b = 7/3 + 2 = 13/3

b = 13/27 ≈ 0.481.
