4 2/3 - 3 1/4 simplify it

Mathematics
1 answer:
DanielleElmas [232]4 years ago
6 0

Answer:

1 5/12

Step-by-step explanation:

First, take 4 and subtract the 3. This leaves you with 1.

Second, take 2/3 and 1/4 and find the least common denominator. In this case, the LCD would be 12.

Now, take 2/3 and and multiply it by 4. You get 8/12. Take 1/4 and multiply it by 3. You get 3/12.

Now that both numbers have a common denominator, you can subtract the numerators. So, 8/12 - 3/12 leaves you with 5/12. Now you have your answer of 1 5/12.

The drawing shown contains the intersection of two lines.
yulyashka [42]
Since they are vertical angles, they equal each other. Therefor the equation would be: 30x-29 = 20x+21
10x = 50
X = 5
After, you plug whatever x is back into the other equations.
20(5)+21 = 121 and 30(5)-29 = 121

The probability of drawing a black marble from a bag is 1/2, and the probability of drawing a white marble from the same bag is
s344n2d4d5 [400]
<span>W = event where white marble is drawn 
B = event where black marble is drawn 

The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule 

P(W and B) = P(w)*P(B) 


Use the rule to get 

P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)

P(W and B) = 1/8 

1/8 is equivalent to 0.125. Use long division or a calculator 

0.125 = 12.5% </span>

Drag point P around the unit circle to find the values of the trigonometric functions.
DanielleElmas [232]

Answer:

See the attachment

Step-by-step explanation:

A unit circle is one whose radius is 1

sin(90) will have coordinates (0,1)

sin(40)= 0.643

sin(40)= P/H= 0.643/1

cos(40)= B/H= 0.766

Similarly for cos(245)= cos(-65)= -0.423/1

                      sin(245)= sin(-65)= -0.906
