The number of light bulbs produced by a company can be modeled by the expression

Mathematics
1 answer:
rewona [7]3 years ago
3 0

Answer:

Expression is 3x² + 5x - 17

Step-by-step explanation:

We are told the number of lights produced by a company is;

Number of lights = 15x^3 + 16x^2 – 100x + 51

Also, number of companies that purchased the light bulbs is 5x - 3.

Thus;

The average number of bulbs purchased per company = (15x^3 + 16x^2 – 100x + 51)/(5x - 3)

I have attached the calculation using long division method to get;

3x² + 5x - 17

The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed
Zolol [24]

Answer:

1 hour

Step-by-step explanation:

The time it takes to travel to a destination varies inversely as its speed

T= k/S

K= TS

Time= 2 hours

Speed= 40mph

K= 2×40

= 80

Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows

T= 80/80

= 1 hour

Hence the new travel time is 1 hour

Fixed Object Involved in Collision Number of Collisions Pole/post 1,416 Culvert/curb/ditch 2,516 Shrubbery/tree 2,585 Guardrail
Genrish500 [490]

Answer:

0.1358 = 13.58% probability of a fatal collision with a pole or post

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

1416 collisions with pole or post.

1416 + 2516 + 2585 + 896 + 947 + 231 + 1835 = 10426 total collisions.

a. What is the probability of a fatal collision with a pole or post?

p = \frac{1416}{10426} = 0.1358

0.1358 = 13.58% probability of a fatal collision with a pole or post

Cuanto cuestan 4 camisetas a $16,000 la docena?
Y_Kistochka [10]
<span>Lo siento, no sé español, pero lo intenté.

Si se trata de "$ 16,000" para una docena de camisas que es 12, se dividiría "16,000 entre 12". Luego obtendrás 1,333.3 para multiplicar eso por 4 y luego obtendrás 5,333.3 a lo que responderás.

 Esta es la ecuación,
16,000 / 12 = 1,333.3 x 4 = 5,333.3
 
Espero que esto ayude :-)</span>
