Answer:

16

Step-by-step explanation:

First, you have to follow the order of operations. (PEMDAS) So you would simplify the numbers inside of the parenthesis, (4*2), and (5-3). The equation then becomes 20 - (8) / (2). Next, you do multiplication and division next, since there is no exponent. 20 - 4. You then simplify the rest by subtracting. 20 - 4 = 16. There is your answer.

A science museum has a spherical model of the earth with a diameter of 6.5 m. What is the volume of the model? Use 3.14 for and

natka813 [3]

radius = diameter/2

radius = 6.5/2 = $\frac{13}{4}$ m

<span>volume </span> $= \frac{4}{3}$ x $\pi$ x (radius)³

$= \frac{4}{3}$ x $\pi$ x $( \frac{13}{4})^3$

$= \frac{4}{3}$ x $\pi$ x $\frac{2197}{64}$

$= \frac{2197}{64}$

= 144 cubic meters

Solve the equation. <br><br><br> 12=2+z/-6

Bogdan [553]

Answer:

$\boxed{\bold{z=-60}}$

Step-by-step explanation:

Switch Sides

$\bold{2+\frac{z}{-6}=12}$

Subtract 2 From Both Sides

$\bold{2+\frac{z}{-6}-2=12-2}$

Simplify

$\bold{\frac{z}{-6}=10}$

Multiply Both Sides By -6

$\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}$

Simplify

$\bold{z=-60}$
