What is the solution to the equation 1/24 x = 1/6? x = 144, x = 30, x = 18, x = 4
alukav5142 [94]

Answer:

x = 4

Step-by-step explanation:

I'd suggest you write (1/24)x = 1/6 to avoid any ambiguity about the coefficient of x.

Multiplying both sides by 24 (the LCD) will eliminate the fractions:

24(1/24)x = 24/6, or x = 4.

What is the value of x to the nearest tenth?
Alex_Xolod [135]
Hi there!

In order to solve for x, we'll need to use a trigonometry ratio. In this case, we'll use tangent, which is opposite over adjacent.

Here is our equation:
tan(37)/1 = x/2.1

Cross-Multiply:
x = tan(37) * 2.1

Solve:
x = 1.8 (rounded to the nearest tenth)

Hope this helps!! :)

A quarter circle is attached to the side of a square as shown.
Radda [10]
The area of the square is s×s
 = 4×4 = 16 m²
The area of a quarter circle is (πr²)/4
    = 3.14 × 16/4
    = 3.14 ×4
    = 12.56 m²
Therefore, the total area is;
     = 16 +12.56
     = 28.56 m²
     ≈ 28.6 m²
