Question 8 (2 points)

SashulF [63]

Answer:

$\mathbf{x=\frac{1}{2}}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

The statement is true.

Option A is correct.

Step-by-step explanation:

We need to determine if $x=\frac{1}{2}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

Solving the equation first to find value of x

$4x+12-8x=-1+2x+10$

Combining like terms:

$4x-8x+12=2x+10-1\\-4x+12=2x+9$

Subtracting 2x on both sides

$-4x+12-2x=2x+9-2x\\-4x-2x+12=9\\-6x+12=9$

Now, subtracting 12 on both sides

$-6x+12-12=9-12\\-6x=-3\\$

Divide both sides by -6

$\frac{-6x}{-6}=\frac{-3}{-6}\\x=\frac{1}{2}$

So, we get $\mathbf{x=\frac{1}{2}}$

Therefore we can say that $\mathbf{x=\frac{1}{2}}$ is the solution to the equation: $4x+12-8x=-1+2x+10$

The statement is true.

Option A is correct.

Oh lord help q-q I have like no time left-

galina1969 [7]

Answer:

(Triangular pyramid)

Lateral area = 1650 $m^{2}$

Total surface area = 1860.1 $m^{2}$

(Triangular prism)

Volume = 660 $cm^{3}$

Step-by-step explanation:

For the triangular pyramid

Area of triangle = $\frac{1}{2}$ × base × height

Area of the base = $\frac{1}{2}$ × 22 × 19.1 = 210.1

Area of the sides = $\frac{1}{2}$ × 22 × 50 = 550

Number of sides (excluding base) = 3

∴ Total Area = 210.1 + (550 × 3)

= 210.1 + 1650 = 1860.1 $m^{2}$

Lateral Area = (550 × 3) = 1650 $m^{2}$

For the triangular prism

Area of the triangle = $\frac{1}{2}$ × 12 × 5 = 30

Volume = Area x Height

Volume = 30 × 22 = 660 $cm^{3}$

the length of a pond is 1700 CM breadth is 14m and height is 1000 CM if a point is half filled calculate the volume of a water i

Andre45 [30]

Answer:

1190 m^3

Step-by-step explanation:

l = 1700 cm = 17 m

b = 14 m

h = 1000 cm = 10 m

Total volume = l × b × h

= 17 × 14× 10

= 2380 m^3

since it is half filled ,

Volume is half , so,

volume of water in pond = 2380 ÷ 2

= 1190 m^3
