HELP!!!IM SO CONFUESED!!!MULTIPLYING FRACTIONS

Mathematics
1 answer:
Ad libitum [116K]2 years ago
3 0
Since there are a lot of questions, let me just show you how to do one.
1/4×3/5
First multiply from left to right, so 1×3 is 4 and 3×5 is 15, so the answer is 4/15. If the final fraction can be reduced, divide it by the GCF and you'll get the answer.

B is the midpoint of 2004-01-01-04-00_files/i0420000.jpg. Find the length of 2004-01-01-04-00_files/i0420001.jpg
damaskus [11]
You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14

Determine the angular velocity, in radians per second, of 14.2 revolutions in 8 seconds
adoni [48]
To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
            
                        n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
                          n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.

Find the inverse of the relation. Use proper notation. {(8,−1),(−8,−1),(−2,−8),(2,8)} please help!!
tiny-mole [99]

Answer: The inverse relation is { (-1, -8), (-1, -8), (-8, -2), (8, 2) }

The inverse is effectively the opposite of the original relation. It undoes what the original relation does. So we'll swap the x and y values for each given point in the form (x,y). Something like (8,-1) becomes (-1,8). The other points follow the same pattern as well.

If an event has a 55% chance of happening in one trial, how do I determine the chances of it happening more than once in 4 trial
aev [14]

The chances of it happening more than once in 4 trials is 13%

<h3>How to determine the number</h3>

From the information given, we have can deduce that;

Probability of 1 trial = 55%

= 55/ 100

Find the ratio

= 0. 55

We are to find the probability of it happening more than once in 4 different trials

If the probability of it happening in one trial is 555 which equals 0. 55

Then the probability of it happening in 1 in 4 trials is given as;

P(1/4 trials) = 1/ 4 × 55%

P(1/4 trials) = 1/ 4 × 0. 55

Put in decimal form

P(1/4 trials) = 0. 25 × 0. 55

P(1/4 trials) = 0. 138

But we have to know the percentage

= 0. 138 × 100

Multiply the values, we have

= 13. 8 %

Thus, the chances of it happening more than once in 4 trials is 13%

Using the technique in the model above, find the missing sides in this 30°-60°-90° triangle.
lina2011 [118]
For this case what you should do is use the following trigonometric relationship:
 sin (x) = C.O / h
 Where
 x: angle
 C.O: opposite leg
 h: hypotenuse
 Substituting the values we have:
 sen (60) = long / h
 sen (60) = 3 / h
 h = 3 / sin (60)
 h = 3.46
 Answer:
 h = 3.46
