A bag contains white,blue and red balls ratio8:3:2 and there are 10 red balls,if 10 white balls and 10 blue balls are removed fr
dmitriy555 [2]

Answer:

New ratio ( white,blue and red) = 6:1:2

Step-by-step explanation:

Given:

Old ratio ( white,blue and red) = 8:3:2

Number of red balls = 10

Removed balls = 10 white , 10 blue

Find:

New ratio ( white,blue and red)

Computation:

Assume total number of balls = x

So,

Number of total balls = 2x / 13 = 10

Number of total balls = 65

Number of white balls = 40

Number of blue balls = 15

So,

Number of new white balls = 40 - 10 = 30

Number of new blue balls = 15 - 10 = 5

New ratio ( white,blue and red) = 30 : 5 : 10

New ratio ( white,blue and red) = 6:1:2

Calculate mpg for w=1000,w=2000;calculate weight when mpg=30
Setler79 [48]

Based on the information above, the car with 1,000 pounds more will only go 1,194 miles, and the one with 2,000 pounds more will only go 1,188 miles.

<h3>What does MPG stand for?</h3>

MPG stands for miles per gallon, and refers to the distance in miles a vehicle travels for each gallon of fuel in its tank.

In general, a car consumes about 1,200 miles per gallon. However, when you add load to it, its fuel consumption is higher because it requires more force to move.

Additionally, some studies state that for every 1,000 pounds of weight added to the car, it will yield 0.5% less. So if the car has 1,000 more pounds, it's not going to go 1,200 miles per gallon, it's going to go 1,194 miles.

On the other hand, if 2,000 pounds of weight were added, the fuel economy would be 1% less, that is, it would travel 1,188 miles per gallon.

Write the following in interval notation:
elena-14-01-66 [18.8K]

Answer:

10/13 ≤ x < 18/13

Step-by-step explanation:

-1 ≤ 13x - 11 < 7

If a ≤ u < b then a ≤ u and u < b

⇒ -1 ≤ 13x - 11  and  13x - 11 < 7

-1 ≤ 13x - 11

Add 11 to both sides:  10 ≤ 13x

Divide both sides by 13:  10/13 ≤ x

13x - 11 < 7

Add 11 to both sides:  13x < 18

Divide both sides by 13:  x < 18/13

Combine the intervals

10/13 ≤ x < 18/13
