Answer: Decompose means the opposite, to take apart. In this lesson, the words composition and decomposition are used to describe how irregular figures can be separated into triangles and other polygons. The area of these parts can then be added together to calculate the area of the whole figure.

Aneli [31]

Answer:

The volume is 2140.98 inches³

Step-by-step explanation

The basketballs are spherical, and it is known that the volume of a sphere is

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

Where V is the volume of the ball and r is its radius


They tell us that the ball measures 8.8 inches wide. This means that its diameter is 8.8 inches.

It is known that the radius of a sphere is equal to half its diameter.

Therefore, the radius r of the ball is:

r = \frac{8.8}{2}

r = 4.4 inches.

Then, they tell us to consider that the walls of the ball are infinitely thin, which means that we should not take into account their thickness in the calculation of the volume.

We already have all the data we need, now we proceed to calculate the volume.

V = \frac{4}{3}\pi(4.4)^{3}\\V = 356.83 inches^{3}

Where V is the volume of only one of the balls

The volume of the six balls is V = 6 * 356.83 = 2140.98 inches³

Finally the volume is 2140.98 inches³

T(x)=70(.80)*+20 where x is the time in minutes and the T is the temperature in degree celsius . What is the initial temperature
Serggg [28]

Answer:

The initial temperature of the coffee was 90°C.

Step-by-step explanation:

The function representing the temperature of the coffee after <em>x</em> minutes is:

T(x)=70\cdot(0.80)^{x}+20

T is the temperature in degree Celsius.

The initial temperature of the coffee will be at <em>x</em> = 0.

Compute the value of T (x) at x = 0 as follows:

T(x)=70\cdot(0.80)^{x}+20

T(0)=70\cdot (0.80)^{0}+20

        =70\times 1+20\\=70+20\\=90

Thus, the initial temperature of the coffee was 90°C.

Solve (x-4)^2=25<br> What method was used?
Serhud [2]
(x - 4)² = 25
x - 4 = \pm √25
x - 4 = \pm 5
x = 5 + 4 or x = -5 + 4
x = 9 or x = -1

Method Use : Completing the square

-------------------------------
Answer: x = 9 or x = -1
