Mathematics
1 answer:
SIZIF [17.4K]3 years ago
3 0

Answer:

x = 257/363

Step-by-step explanation:

8x+32=15(25x-15)-4x

8x+32=375x-225-4x

8x+32=371x-225

8x-8x+32+225=371x-8x-225+225

257=363x

x=\frac{257}{363}

13. The radius of Earth is approximately 6.4 x 100 m. Use the formula V = 4/3pr^3
romanna [79]

<u>We are given</u>

  • Radius of Earth; 6.4 x 100 meters = 640 meters

Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

\implies \text{Volume of sphere =} \   \dfrac{4\pi r^{3}}{3}

When we substitute the radius in the formula, we get;

\implies\text{Volume of sphere} = \dfrac{4\pi (640)^{3}}{3}

\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}

Take π as 3.14

\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}

\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}

Simplify the numerator;

\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}

\implies \text{Volume of sphere} = \dfrac{3292528640}{3}

Divide the numerator by 3;

\implies \text{Volume of sphere} = \dfrac{3292528640}{3}

\implies \text{Volume of sphere} = \boxed{1097509546.67 \ \text{m}^{3} } \ \ \ (\text{Estimated})

Last winter Armand had 5/6 of a row of stacked logs . At the end of the winter he had 8/15 of the same row left . How much wood
matrenka [14]
5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row

The first programmer can write an app in 10 days. The second programmer can finish the same job in 8 days. How long would it tak
liubo4ka [24]

Answer:

4 4/9 days.

Step-by-step explanation:

You work in rates per day, so:

1/10 + 1/8 = 1/x     where x is the number of days working together.

Multiply through by  the LCD 40x:

4x + 5x =  40

9x = 40

x = 40/9 = 4 4/9 days.
