RSB [31]2 years ago
6 0

Answer:

Part A is ≤ means less than OR equal to. < only means less than

Part B is 9

Step-by-step explanation:

A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?<br> a 3<br> b 4<br> c 5<br> d 9
Pepsi [2]
The answer would be B) x = 4.

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 = 4.5x - 9 - 1.5x

3 = 3x - 9

3 + 9 = 3x

12 = 3x

12/3 = x

4 = x

x = 4.

The area of this circle is 96π m². what is the area of a 30º sector of this circle?
dlinn [17]
Answer: 8π square meters

Explanation: 

First, we convert the angle of the sector to radians, which is 30 degrees. 

Note that 180 degrees is equal to π radians. Since 30 degrees is equal to 180 degrees divided by 6, 

30 degrees = π/6 radians

Thus, the angle of the sector in radians is π/6.

So, the area of the sector is given by 

(Area of sector) = (1/2)(radius)²(angle of the sector in radians)
                          = (1/2)(radius)²(π/6)
                          = (π/12)(radius)²
                          = (1/12)(π)(radius)²

Note that

(Area of the circle) =  (π)(radius)² = 96π

Therefore, the area of the 30-degree sector is given by 

(Area of the sector) = (1/12)(π)(radius)²
                                = (1/12)(Area of the circle)
                                = (1/12)(96π)
(Area of the sector) = 8π square meters
