Answer:

Step-by-step explanation:

Find LCM of 4,5,8 = 40

Then find equivalent fractions

2/4 = 2*10/4*10 = 20/40

3/5 = 3*8/5*8 = 24/40

6/8 = 6*5/8*5 = 30/40

20/40+24/40+30/40 = (20+24+30)/40

= 74/40 = 37/20

Answer:

Step-by-step explanation:

1) Change the fractions so that they all have common denominators (2/4 --> 20/40,  3/5 --> 24/40,  6/8 --> 30/40)

2) Add the numerators together (74/40)

3) Simplify as necessary

Someone solve this equation much appreciated!
daser333 [38]

Answer:

\frac{2A}{h} = b

Step-by-step explanation:

  • this can be done by simple manipulation .
  • in the given equation, A is the subject.
  • so, by the above statement you can understand the meaning of making something as a subject.
  • given equation: A = 1/2 bh
  • multiply both the sides by 2,

2A = bh

  • divide both the sides by h,

\frac{2A}{h} = b

so, the required form is : \frac{2A}{h} = b

Using the function concept, it is found that f is a function, as each student is related to only one GPA and only one number of credits.

In a function, <u>one value of the input can be related to only one value of the output</u>.

In this problem:

  • The input is the student.
  • The output is the student GPA, and the number of credits earned.

Each student is related to only one GPA and only one number of credits, hence <u>one value of the input is related to only one value of the output</u>, and f is a function.

Alecsey [184]

The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of an a standard earthquake .

<h3>What is magnitude of earthquake?</h3>

Magnitude of earthquake is the measure of the size of origin of the earthquake. The magnitude of the earthquake keeps the same value for each place.

An earthquake with a magnitude of about 2. 0 or less is called a micro-earthquake and not felt usually.The intensity of an earthquake with a magnitude of 2.

Let the intensity of this earthquake is <em>n </em>times greater than the intensity of an a standard earthquake. Thus the intensity of standard earthquake can be given as,

n=10^2\\n=100

If the magnitude would be 3 then the intensity would be,

n=10^3\\n=1000

It would be 1000 times greater than the standard earthquake and so on.

Thus, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of an a standard earthquake .
