What is the best estimate for the sum of 3/4 and 1/12

Answers

Answer 1
Answer: well first you would find a common denominator which would be 1w and then since you multiplied 4 by 3 to get to 12 you multiply 3 by 3 which is 9. So then you would have 9/12 + 1/12 which = 10/12

What is 19% of 72? I NEED TO KNOW HOW YOU GOT THE ANSWER TO!!

Answers

First you must multiply the number by the percent. (19*27= 513)
Then you divide the answer by 100, or move decimal two places to the left. (513/100= 5.13)
Then round to the nearest whole number (5.13 is approximately 5)
Therefore 19%of 27 = 5

I need to solve for x and y. Any help is greatly appreciated! Thank you!

Answers

x=-3, y=1

Step-by-step explanation:

Given equations are:

2x-3y=-9     Eqn 1

x+y = - 2      Eqn 2

From eqn 2:

x=-y-2

Putting x=-y-2 in eqn 1

2(-y-2)-3y=-9\n-2y+4-3y=-9\n-5y-4=-9\nAdding\ 4\ on\ both\ sides\n-5y-4+4=-9+4\n-5y=-5\nDividing\ both\ sides\ by\ -5(-5y)/(-5)=(-5)/(-5)\ny=1\nPutting\ y=1\ in\ eqn\ 2\nx+1=-2\nSubtracting\ 1\ from\ both\ sides\nx+1-1=-2-1\nx=-3

Hence,

x=-3, y=1

Suppose that, in 2006, Poland produced 4.02 million bikes. The total world production that year totaled 142 million bikes. What percent of the world's total production of bikes is contributed by Poland? Round your answer to the nearest tenth of a percent.

Answers

The percent of the world's total production of bikes that is contributed by Poland is 2.83%.

Number of bikes produced by Poland = 4.02 million bikes.

Number of bikes produced by the world population = 142 million bikes.

The percent of the world's total production of bikes that is contributed by Poland will be:

= (4.02/142) × 100

= 2.83%

Therefore, the percent of the world's total production of bikes that is contributed by Poland is 2.83%.

Here goes another question: 4/5%9/10 and please if you can with procces

Answers

When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

(4)/(5) * (10)/(9) = (40)/(45) = (8)/(9)

Answer= 8/9

8/9 is the answer to your question
