Answer:

7.8 units separate the points A and B.

Step-by-step explanation:

Going from B to A, x increases by 6 (this is the horizontal side of the triangle formed by vertices A and B), and y increases by 5. Applying the Pythagorean Theorem, we get

d = √(6² + 5²), or √(61, which is approximately 7.8, the desired distance.

Enter the ratio as a fraction in lowest terms 14 minutes to 18 minutes

Mademuasel [1]

Answer:

Part A is 7/16 of the whole
Part B is 9/16 of the whole

Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 14 + 18 = 32

Part A = 14 and Part B = 18 are numerators for each fraction.

The fractions are then:
14/32 and 18/32

Meaning:
Part A is 14/32 of the whole
Part B is 18/32 of the whole

Reducing the fractions, it is also true that:
Part A = 7/16 of the whole
Part B = 9/16 of the whole

Point A is located at (3,6). The midpoint of line segment AB is point C(11,13). What are the coordinates of point B? Use the mid

lesya692 [45]

Answer: The coordinates of point B are (19 , 20).

Step-by-step explanation:

The mid point (x,y) of line joining (a,b) and (c,d) is given by :-

$(x,y)=(\dfrac{a+c}{2},\dfrac{b+d}{2})$ (1)

Given : Point A is located at (3,6). The midpoint of line segment AB is point C(11,13).

Let the coordinates of point B are (a,b) m, the according to (1) , we have

$(\dfrac{3+a}{2},\dfrac{6+b}{2})=(11,13)\\\\\Rightarrow\ \dfrac{3+a}{2}=11\ \ ,\ \ \dfrac{6+b}{2}=13\\\\\Rightarrow\ 3+a=22\ \ ,\ \ \ 6+b=26\\\\\Rightarrow\ a=19,\ \ b= 20$

Hence, the coordinates of point B are (19 , 20).
