Which of the following is an example of a proper fraction? A. 4 /3 B. 4 /4 C. 3 /4 D. 7 /6

Answers

The proper fraction is c. 3/4. A proper fraction is a fraction that is less than one. A fraction is less than one if its denominator, the number below the line, is larger than its numerator, the number above the line. 4/3 and 7/6 are both greater than one and 4/4 is equal to one, thus none of them are proper fractions.t

3/4 is the correct answer

On Monday, it took Helen 3 hours to do a page of science homework exercises. The next day she did the same number of exercises in 2 hours. If her average rate on Monday was pexercises per hour, what was her average rate the next day, in terms of p?

Answers

p- it is amount of exercises
average= $(exercises)/(hour)$
Monday average= $(p)/(3h)$
Tuesday average= $(p)/(2h)$
If we take into account both days and calculate average from Monday and Tuesday ( we sum 3h on Monday and 2 hours on Tuesday and p exercises on Mon and p exercises on Tuesday):
Monday and Tuesday average= $(2p)/(5)$

The y-intercept of the line whose equation is 2x + 5y = 8 is 8 4 8/5

Answers

to get y- intercept
put x=0 in the equation
2(0) +5y = 8
so,, y = 8/5

Final answer:

The y-intercept of the line represented by the equation 2x + 5y = 8 is 8/5. This is determined by rewriting the equation in slope-intercept form (y = mx + b), where 'b' represents the y-intercept.

Explanation:

The subject of this Mathematics question seems to be focusing on finding the y-intercept of the equation 2x + 5y = 8. In an equation like this, formatted in the style of a linear equation (y = mx + b), the y-intercept is represented by 'b'. This intercept is the point at which the line crosses the y-axis in a Cartesian plane.

If we rearrange the equation to the format y = mx + b, we get y = -2/5*x + 8/5. Therefore, the y intercept of the equation 2x + 5y = 8 is 8/5, which is the 'b' in our slope-intercept form equation.

What is 1/9 of 63% of $6,000?

Answers

Answer:

The answer is $420

Step-by-step explanation:

The procedure is multiply the number 6000 by 63% and $(1)/(9)$ . The order of these multiplying doesn't matter.

The percentage number can be changed into a fraction number following the next rule:

Give a x number in a range from 0 to 100:

x%= $(x)/(100)$

So,

63%= $(63)/(100)=0.63$

$(1)/(9)*0.63*6000=420$

Finally, the answer is $420

The answer is $420. Multiply 6,000 by 0.63 to find 63% of 6,000. That gives you 3780. Then to find 1/9 of 3780, divide it by 9. The answer is 40.
