A tennis ball weighs about 57.6 grams. about how many apuntes would 12 tennis balls weigh?
Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

Step-by-step explanation:

The weight of each  tennis ball =  57.6 grams

So, the weight of 12 balls    =    12 x ( weight of 1 ball)

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams

National Textile installed a new textile machine in one of its factories at a cost of $250,000. The machine is depreciated linea
kirill115 [55]

Answer:

The required expression is y=250,000-24,000 t

Step-by-step explanation:

Consider the provided information.

National Textile installed a new textile machine in one of its factories at a cost of $250,000.

That means for 0 year the cost of the machine is $250,000.

This can be written as: (0, 250,000)

Over 10 years with a scrap value of $10,000

That means for 10 year the cost of the machine is $10,000.

This can be written as: (10, 10,000)

Now first find the rate of change:

Rate of change=m=\frac{Rise}{Run}=\frac{10,000-250,000}{10-0}

Rate of change=m=\frac{Rise}{Run}=\frac{-240,000}{10}

Rate of change=m=\frac{Rise}{Run}=-24,000

Now use the point-slope form of an equation of a line with the point (0, 250,000), we can find the required expression.

(y-250,000)=-24,000(t-0)

y-250,000=-24,000 t

y=250,000-24,000 t

Hence, the required expression is y=250,000-24,000 t
