B. 24
C. 100
D. 96

4. Which one of the following statements expresses a true proportion?
A. 3:4 = 9:12
B. 2:1 = 1:2
C. 7:9 = 8:9
D. 54:9 = 6:3

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

3)Total no of people surveyed = 400

Percentage of people preferred WCLM = 24%

Hence no of people who preferred WCLM = 24(400)/100

=96

4)

3:4 =9:12 is true since when simplified both are equal

B is not right 2:1 cannot equal 1:2 as ratio is not commutative

c is not right as they are not equal when simplified

D is not right since when we divide left side by 9, we get 6:1
Answer 2
Answer:

Answer:

A

Step-by-step explanation:

9 divided by 3 gives 3

12 divided by 3 gives 4

therefore 9:12 is equal to 3:4

Solve the equation 36x^2 25=0

Answers

The equation 36x^2 + 25 = 0 possesses no real solutions; however, it yields two complex roots: x = (5/6)i and x = -(5/6)i.

The equation provided, 36x^2 + 25 = 0, is a quadratic equation in one variable, x. To solve it, we'll first isolate the x^2 term:

36x^2 = -25

Next, we'll divide both sides by 36:

x^2 = -25/36

Taking the square root of both sides, we get:

x = ±√(-25/36)

Since the square root of a negative number is imaginary, there are no real solutions to this equation. This means that the equation 36x^2 + 25 = 0 has no real roots, but it does have complex roots in the form of x = ±(5/6)i, where i is the imaginary unit.

The equation 36x^2 + 25 = 0 has no real solutions, but it does have two complex solutions: x = (5/6)i and x = -(5/6)i.

Would assume it to be 36x² - 25 = 0

36x² - 25 = 0

(6x)² - 5² = 0

(6x + 5)(6x - 5) = 0         By difference of two squares.

6x + 5 = 0           or         6x - 5 = 0

6x = -5                             6x = 5

x = -5/6                              x = 5/6

x = +5/6   or - 5/6

Which equation represents the line that passes through (-8,11) andand (4, 7/2)?

A) y = -5/8x + 6
B) y = -5/8x + 16
C) y = 15/2x - 49
D) y = -15/2x + 71

Answers

Answer:

A) y = -5/8x + 6

Step-by-step explanation:

y2 - y`1 / x2 - x1

7/2 - 11 / 4 - (-8)

-15/2  / 12

= -5/8

y = -5/8x + b

11 = -5/8(-8) + b

11 = 5 + b

6 = b

Answer:

Option (A)

y = - 5 / 8 x + 6

Step-by-step explanation:

Two points are

(x', y') = ( - 8, 11 )

(x'', y'') = (4, 7/2)

The equation o line passing through two points is given by

(y - y') = (y'' - y')/(x''-x')(x-x')\n\n(y - 11)= ((7)/(2)-11)/(4+8) (x + 8)\n\ny - 11 = (-5)/(8)(x + 8)\n\ny -11 = (-5x)/(8) - 5\n\ny = (-5x)/(8) + 6

So, option (A) is correct.
