Answer: 510 meters

Step-by-step explanation:

Given: The table shows the distance traveled by an object moving at a constant speed.

We know that the $\text{speed}=\frac{\text{distance}}{\text{time}}$

From table in 10 seconds the distance traveled = 85 meters

$\\\\\Rightarrow\text{speed}=\frac{85}{10}=8.5$ meters per second

If Time = 1 minutes

Also, 1 minute=60 seconds

Since, speed is constant , then the distance traveled in 1 min is given by :_

$\text{distance}=\text{speed}\times\text{time}\\\Rightarrow\text{distance}=8.5\times60=510\text{ meters}$

If the object moves 170 meters in 20 seconds. There are 60 seconds in a minute. You have to multiply the 170 by 3. One minute it moves 510 meters

Answer:

Step-by-step explanation:

Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.

Let x represents the amount of good quality forever paint sold.

Total amount of paint $=48+45+35+39+33+x=200+x$ ...(i)

Experimental probability of paint sold will be better quality durable paint is

$P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}$

$P=\dfrac{45}{\text{Amount of total paint}}$

It is given that experimental probability of paint sold will be better quality durable paint is $\frac{9}{50}.$

$\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}$

$\text{Amount of total paint}=\dfrac{45\times 50}{9}$

$\text{Amount of total paint}=250$ ...(ii)

From (i) and (ii), we get

$200+x=250$

$x=250-200$

$x=50$

Therefore, 50 gallons good quality forever paint is sold.

Answer:

See below.

Step-by-step explanation:

(a)

To multiply two polynomials, multiply every term of the first polynomial by every term of the second polynomial. Then combine like terms.

$(\dfrac{1}{2}x - \dfrac{1}{4})(5x^2 - 2x + 6) =$

$= \dfrac{1}{2}x \times 5x^2 - \dfrac{1}{2}x \times 2x + \dfrac{1}{2}x \times 6 - \dfrac{1}{4} \times 5x^2 + \dfrac{1}{4} \times 2x - \dfrac{1}{4} \times 6$
