Answer: 52.5%

Step-by-step explanation:

First add up both quantities to find out the total quantity of the mixture.

= 2.85 + 3.15

= 6 kg

The flour is 3.15 kg out of this total so the percentage is:

= 3.15 / 6 * 100%

= 52.5%

Answer:

6/5

Step-by-step explanation:

you'd divide the second number by the first number

30/25= 6/5

The fraction in the simplest terms, is 6/5 which is multiplied by the first number by to get the second.

A fraction is a part of a whole number, and a way to split up a number into equal parts. It is written as the number of equal parts being counted, called the numerator, over the number of parts in the whole, called the denominator.

Given that, what fraction should be multiplied to 25 to get 30,

Let the fraction be x/y

Therefore,

25·x/y = 30

x/y = 30/25

x/y = 6/5

Hence, the fraction in the simplest terms, is 6/5 which is multiplied by the first number by to get the second.

Answer: 32/12 as a mixed number is 2 2/3

Step-by-step explanation: First you see how many 12's can go into 32 which is 2 right? So after you see how much you have left over. Which is 8 and now its 2 and 8/12 but you want the simplest form which you can find by seeing what goes into 8 and 12 which is 4, so now you divide 8 by 4 and 12 by 4 which is 2 over 3

Answer:

Answer:

Yes, (0, 1) is the solution of the given inequality.

Step-by-step explanation:

To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.

If the inequality is true for the ordered pair it will be the solution.

Inequality is,

y > x - 1

For (0, 1),

1 > 0 - 1

1 > -1

True.

Therefore, ordered pair (0, 1) is the solution of the given inequality.

Answer:

8 years

Step-by-step explanation:

There are 50 lights present in the building and each light cost $50. Therefore the cost of changing all the bulbs is:

Cost = number of lights * cost per light = 50 lights * $50 = $2500

Changing the lights in the building save the company $305 per year in energy cost. Therefore, the number of years required for the new lights to pay for themselves is:

number of years = cost of changing bulbs / money saved per year

number of years = $2500 / $305 per year = 8.2

number of years = 8 years to the nearest year
