Answer:1/4
hope this helps
Step-by-step explanation:We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 3 by 12, and get 36.
Then we multiply 6 by 4, and get 24.
Next we give both terms new denominators -- 4 × 12 = 48.
So now our fractions look like this:
36/48 − 24/48
Step 2
Since our denominators match, we can subtract the numerators.
36 − 24 = 12
So the answer is:12/48
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
12/48÷ 2 =6/24
Let's try dividing by 2 again
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
6/24÷ 2 =3/12
Let's try dividing by 2 again...
Nope! So now we try the next greatest prime number, 3...
Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:3/12÷ 3 =1/4
Let's try dividing by 3 again
No good. 3 is larger than 1. So we're done reducing.
There you have it! The final answer is:
3/4−6/12=1/4

A man earns rs 24000 per month and spends 70% of it find his monthly saving
Answer:
Savings=rs7200
Step-by-step explanation:
money spend=70% of 24000
=70/100*24000
=70*240
=rs 16800
savings=money earned-money spend
=24000-16800
=rs7200
Answer: rs 7200
Step-by-step explanation: So 70% of 24000 = 16800
24000-16800=7200
so he spends rs 16800 per month and has a saving of Rs 7200 per month from his monthly salary.

An athlete runs a distance of 345 metres (to the nearest metre) in a time of 44.6 seconds (to the nearest 0.1
second).
What is her slowest possible speed?
Answer:
7.716 (with margin: 0.001)
Step-by-step explanation:
speed = distance ÷ time
For speed to be at a minimim you need distancemin ÷ timemax
Min distance = 345 - 0.5 = 344.5m
Max Time = 44.6 + 0.05 = 44.65 sec
speedmin=344.5 ÷ 44.65 = 7.7155..... = 7.716 m/s (3 dp)
The slowest speed possible of the athlete is required.
The minimum possible speed of the runner is 7.7 m/s.
Speedd = Distance run by the athlete = 345 meters
t = Time taken by the athlete to cover the distance = 44.6 seconds
Speed is given by
[tex]s=\dfrac{d}{t}[/tex]
[tex]s=\dfrac{345}{44.6}[/tex]
[tex]s=7.735\approx 7.7 \text{m/s}[/tex]
The speed of the athlete should be at least 7.7 m/s any less than that and the athlete will not be able to cover the required distance in the given time.

In triangle ABC, M is the midpoint of AB. Let D be the point on BC such that AD bisects angle BAC, and let the perpendicular bisector of AB intersect AD at E. If AB = 44, AC = 30, and ME = 10, then find the area of triangle ACE.
Help Please!
The area of Triangle ACE from the given diagram is; 150 sq.units
What is the area of the triangle?We are given;
AB = 44
AC = 30
ME = 10
Now, to find the area of triangle ACE, we need to know the length KE where K is the midpoint of AC.
Now, since AD bisects angle BAC. This means that ∠KEA = ∠MEA.
By ASA Congruence Postulate, we can say that; ΔAEK ≅ AEM
Thus, we can say that KE = ME = 10
Formula for area of triangle is;
A = ¹/₂ * base * height
where;
base = AC = 30
Height = KE = 10
Thus;
A = ¹/₂ * 30 * 10
A = 150

The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. if an object travels 30 meters in 20 seconds, what is its speed?
Answer:
1.5 meters per second.
Step-by-step explanation:
Distance formula:
d = rt
where d = distance, r = average speed and t = time traveled.
They told us that an object travels 30 meters in 20 seconds.
So we can say d = 30 and t = 20
if you put these values back into the distance formula you get:
d = rt
30 = r times 20
30 = 20 r
So now we want to find what "r" (average speed) is.
Divide both sides by 20.
20 r = 30
r = = 1.5 meters per second.

Solve the following problem. Give the equation using x as the variable, and give the answer.
The sum of three times a number and 8 more than the number is the same as the difference between −22 and twice the number. What is the number?
Question content area bottom
Part 1
Write the equation using x as the variable. Choose the correct equation below.
A.
3x+(x+8)=−22−2x
B.
3x−8x=2x−(−22)
C.
3x−8x=−22−2x
D.
3x+(x+8)=2x−(−22)
Answer:
A. 3x + (x+8) = -22 - 2x
Step-by-step explanation:
Let the number equal x.
Set up the first half of the equation.
The sum of three times the number and 8 more than the number can be written as:
3x + (x+8)
Sum means that you add the components.
Set up the second half of the equation.
The difference between -22 and twice the number can be written as:
-22 - 2x
Difference means subtraction, and because -22 is written first, that is the number that you subtract from.
If you set the halves of the equation equal, you get:
3x + (x+8) = -22 - 2x
Therefore, the answer is A.

In rectangle EFGH, EH I FG and EH crosses the y-axis at (0.-2). If the equation of the line containing FG is x + 3y = 12, write the equation of the line containing EH in slope- intercept form. Show your work to justify your answer.
Answer:
y = (-1/3)x - 2
Step-by-step explanation:
First we should put the equation for FG into slope intercept form, which is y = mx + b. For this step, just solve for the y in the equation, which should be y = (-1/3)x + 4.
Next, since we know that FG and EH are parallel, their slopes must also be the same. We also know the (0, -2) is a point on EH, and also happens to be the y-intercept. Therefore, we can plug it back into the slope intercept equation and get y = (-1/3)x - 2, since the m is the same and the -2 is just the y-intercept given in the problem.
