Please I just need help with these two problems
Oksana_A [137]

1.

3d-4+d=8d+12 \implies \\4d-4=8d+12 \implies-4d=16 \implies\\ d=-4

2.

f-6=-2f+3(f-2) \implies \\ f-6=-2f+3f-6 \implies\\  f-6=f-6 \implies\\ 0=0 \implies \text{ all real numbers are a solution to this problem}

SOLVE THE EQUATION 2X - 4 = 16​
vladimir1956 [14]

Answer:

x = 10

<u></u>

Step-by-step explanation:

2x - 4 = 16             try to get x on the left side, and the integers on the right

You then get:

2x = 20

Now, divide by 2 on both sides

2x/2 = 20/2

<u>x = 10</u>

Determine the mass of a solid steel ball that has a diameter of 10 cm. The density of pure steel is 8.09 g/cm3
Basile [38]

Answer:

<em>The mass of the steel ball is 4,235.9 gr</em>

Step-by-step explanation:

<u>Density</u>

The density ρ of a substance is a measure of its mass per unit volume:

\displaystyle \rho=\frac{m}{V}

If the density and the volume are given, the mass can be calculated by solving the above formula for m:

m=\rho.V

We know the density of pure steel ρ=8.09 gr/cm3 and the diameter of a solid steel ball d=10 cm.

We need to calculate the volume of the sphere:

The volume of a sphere of radius r is given by:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3

The radius is half the diameter: r= 10/2 = 5 cm. Thus:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot 5^3

Calculating:

V=523.6\ cm^3

The mass is:

m=8.09 gr/cm^3 \cdot 523.6\ cm^3

m=4,235.9 gr

The mass of the steel ball is 4,235.9 gr
