Answer: Given : points 4 , 1 ,25 , opposite of 3 , -1/2To Find : draw on Number Line Solution :Numbers with a negative sign are less than zeroRight of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.+ sign numbers can be denoted as simply numbers On a number line the number increases as we move to the right and decreases as we move to the left. 1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on 2. Go 4 unit on right sides from Zero to show 43. Go 3 units on Left from zero to show opposite of 3 4. Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 15.

What is the division expression that is the same as 1/5 * 1/4 ?
A. 1/5 divide by 2
B. 1/5 divide by 3
C. 1/5 divide by 4
D. 1/5 divide by 5

Answers

Answer:

C. 1/5 divide by 4

Step-by-step explanation:

When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).

Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.

Now that we have some back ground information, let's which expression leads to 1/20!

1/5 x 2/11/5 x 1/21/10Incorrect Answer Choice

1/5 x 3/11/5 x 1/31/15Incorrect Answer Choice

1/5 x 4/11/5 x 1/41/20Correct Answer Choice!

Therefore, the answer is C. 1/5 divide by 4.

What's Ali's average speed on her walk to school if she walks halfway at 2mph and runs the rest of the way at 7mph?

Answers

Answer:

s = 28/9

Step-by-step explanation:

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9

The average speed is 28/9.

What is Average speed?

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

Example

Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.

To find the average speed we need the total distance and the total time.

Total distance covered by Sam = 200Km + 160 km = 360 km

Total time taken by Sam = 4 hour + 4 hour = 8 hour

Average Speed = Total distance covered ÷ Total time taken

Average Speed = 360 ÷ 8 = 45km/hr

The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:

Average Speed Formula:

Average Speed = Total distance covered ÷ Total time taken

Given:

halfway at 2mph and runs the rest of the way at 7mph

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9 mph

When you simplify -6+4q+(-6q), you'll end up with -2q-6, which isn't present between the two choices.

-6(q+1)-4q = -10q-6, so that can't be the answer

2(q-3) = 2q - 6. But the 2q isn't negative, so therefore, this isn't the answer either

Therefore, the answer is C: None of the above
