In the school band, there are 4 trumpet players and F flute players.The total number of trumpet and flute players is 12. Are there are twice as many flute players as trumpets players? Explain

Answers

There is 8 flute players and yes there is twice. Because in total there are 12 instrument players so you could subtract 4 from 12 it will equal 8 and its twice of trumpet players.

Yes. Because 4 twice is 8. And since there are only four flute players, there will be 8 leftover players, making those 8 leftover players the flute players. Since twice of 4 is 8, and there are 8 flute players, there are twice as many flute players than trumpet players.

the African bush elephant weighs between 4.4 tons and 7.7 tons. what are its least and greatest weights , rounded to the nearest ton

Answers

Answer: Least and greatest weights of the African bush elephants are 4 tons and 8 tons respectively.

Step-by-step explanation:

Weight of the African bush elephant = 4.4 tons

Weight of the African bush elephant = 7.7 tons

So, Least weights of the African bush elephants =4.4

Rounded to nearest ton = 4 tons

And ,

Greatest weights of the African bush elephants = 7.7

Rounded to nearest ton = 8 tons

Hence, least and greatest weights of the African bush elephants are 4 tons and 8 tons respectively.

It's 4 tons and 8 tons because if is 5 or more then you round up and if it's less than 5 you round down ;)))

Please help with the question 2 to 18

Answers

Since these questions all require similar methods of solving, I will only completely work out the first question of each type.

2. To find $(7)/(10)$ as a decimal, all we need to do is complete the fraction by dividing the numerator by the denominator.

$(7)/(10)$ = 7 / 10 = 0.7

$(7)/(10)$ as a decimal is 0.7.

3. To write a fraction as a percentage, we must first convert it into a decimal, the way we did in problem 2.

$(13)/(20) =0.65$

Then to change that number into a percentage, we can either multiply it by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

0.65 = 65%

which is the answer to question 3.
$(13)/(20)$ written as a percent is 65%.

4. Writing a percentage as a fraction is a bit easier than writing a fraction as a percentage. All you need to do is place the percentage in the numerator's place of a fraction with 100 as the denominator and simplify.

2%5 = $(25)/(100)$

Since 25 goes into 100 four times, we can simplify this fraction.

$(25)/(100) = (1)/(4)$

which is our answer.

25% written as a fraction is $(1)/(4)$ .

5. This is the same as problem 3, so I won't show my work for the sake of time.

$(2)/(5)$ as a percentage is 40%.

6. This is the same as problem 1, so I will not show steps again.

$(3)/(20)$ as a decimal is 0.15.

7. Done similar problems in past. No work shown.

$(21)/(50)$ as a percent is 42%.

8. Same as last problem.

$(1)/(25)$ as a percent is 4%.

9. Same as number 4.

6% as a fraction is $(3)/(50)$ .

10. Similar in past.

$(3)/(5)$ as a percentage is 60%.

11. Same as 6.

$(12)/(25)$ as a decimal is 0.48.

12. Done a lot of these so far.

$(3)/(10)$ as a percentage is 30%.

13. Just did one like this.

$(3)/(4)$ as a percentage is 75%.

14. Same as 4 and 9.

65% as a fraction is $(13)/(20)$ .

15. Plenty of these done in past.

$(1)/(5)$ as a percentage is 20%.

16. Last problem, and it's just like the one just before this.

$(9)/(10)$ written as a percent is 90%.

So there are the results.
Hope that helped! =)

2. 7/10 as a decimal.

The easiest way to find the decimal form of a fraction is to make it out of 10 or 100. Since this one's already out of 10, we read it as "seven tenths."

Seven tenths as a decimal is 0.7, because the 7 is in the tenths spot.

7/10 as a decimal is 0.7

3. 13/20 as a percent

Percent means "one part in every hundered", so let's convert this fraction into something out of 100.
To do that, we need to multiply it by whatever number will turn the denominator into 100.

20 x 5 = 100
13 x 5 = 65

13/20 is equal to 65/100

Now, we take the numerator, and write it as a percent.

65/100 is 65%

Therefore 13/20 as a percent is 65%

4. 25% as a fraction.

We can do this one the opposite of #3.

25% is 25/100

And then we can just simplify. 5 goes into both 25 and 100, so let's use that first.

25 ÷ 5 = 5
100 ÷ 5 = 20

25/100 = 5/20

But we can simplify it further, if we want, because 5 goes into 5 and 20

5 ÷ 5 = 1
20 ÷ 5 = 4

25/100 = 5/20 = 1/4

So 25% as a fraction can be written as 25/100, or 5/20, or 1/4.

Now, #5-16 can all be done the same way as #2, 3, or 4, so I'll write out the math, but not the lengthy explanation for the rest.

5. 2/5 as a percent

#17 and 18 require a bit more math, because they're lovely word problems.

17. Ashlee has finished 7/25 of her homework. What percent of the homework does Ashlee still need to finish?

First, let's turn 7/25 into a percentage.

25 x 4 = 100
7 x 4 = 28
28/100
28%

Now, we subtract 28% from 100% to find out how much she's got left

100 - 28 = 72

Ashlee has 72% of her homework left to finish.

18. Luz catches 83% of the balls in the outfield. What fraction of the balls does he not catch?

Let's turn 83% into a simple fraction, and work from there.

83%
83/100

We can simplify the answer later, but for now, to find the fraction he doesn't catch, we subtract the fraction from the whole.

100/100 - 83/100 = 17/100

17 is a prime number, so we can't reduce it down at all.

Luz doesn't catch 17/100 of the balls.

3 times what equals 44

Answers

The number times 3 that will give 44 is approximately 14.7.

How to solve equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Therefore, let's represent the question in an equation form and find the number.

3 times what equals 44

let

the number = x

Therefore,

3 × x = 44

3x = 44

divide both sides by 3

x = 44 / 3

x = 14.7

Therefore, the number is approximately 14.7

44 divided by 3 = 14.6666...You divide, because you have to do the inverse operation of multiplication, which is division.

Suppose you are doing a 5,000 piece puzzle. you have already placed 175 pieces. Every minute you place 10 more pieces. Write and equation in slope intercept form to model the number of pieces placed. Is this relationship linear, how do you know?

Answers

y=mx+b

5,000=10x+175

Where x equals minutes spent working on the jigsaw.

Final answer:

The equation modelling the given scenario in slope-intercept form is y = 10x + 175, which represents a linear relationship because the rate at which puzzle pieces are being placed,10 per minute, is constant.

Explanation:

The subject of your query falls into the category of linear algebra, specifically, slope-intercept form equations and linear relationships in mathematics. In slope-intercept form, a line can be described by the equation y = mx + b, where 'm' represents the slope and 'b' signifies the y-intercept.

For your puzzle scenario, 'm' is the number of puzzle pieces you place each minute, which is 10, and 'b' is the initial number of pieces already placed which is 175. Therefore, the equation that models your situation is y = 10x + 175.

This relationship is, indeed, linear. We know this because the rate at which you are placing puzzle pieces is constant, meaning it doesn't change over time. This is characteristic of a linear relationship, as represented by the straight line on a graph. In other words, for every unit increase in time (x), the number of puzzle pieces placed (y) increases at a steady rate of 10.
