Consider x+4=x+8. What values could be substituted for x to make this a true number sentence?
Schach [20]

This looks unusual but let's try it.

x+4=x+8

Let's move the x vales to the left and numbers to the right.

x-x=8-4

0=-4

Hm. This doesn't work, does it?

This equation has no solution. If you believe you typed it wrong, correct it in the comment seciton.

iren [92.7K]
This is simple long multiplication. 347 x 270 is 93,690. Then you divide this number by the amount of acres, in this case, 3. So 93,690/3 is 31,230. Hope this helped

A heap of grain is shaped as a cone ADCF with height 5 m and base radius 2 m, as shown on the diagram. A and C are points on the
hoa [83]

Answer:

The angle between [A_F] and the base of the cone = 68.2°

The area of the base of the cone ≈ 12.57 m²

Step-by-step explanation:

The given parameters are;

The height of the cone = 5 m

The base radius of the cone  = 2 m

The angle which the A\hat OC = 120°

Therefore, we have;

The angle between [A_F] and the base of the cone = The angle between [CF]  and the base of the cone

The angle between [CF]  and the base of the cone = tan⁻¹(5/2) = tan⁻¹(2.5) ≈ 68.2°  

∴ The angle between [A_F] and the base of the cone = The angle between [CF]  and the base of the cone = 68.2°

The angle between [A_F] and the base of the cone = 68.2°

The area of the base of the cone = π × r² = π × 2² = 4·π ≈ 12.57

The area of the base of the cone ≈ 12.57 m².
