Use the Distance Formula to find the distance to the nearest tenth between A(-7, -4) and B(-2, 0).

goldenfox [79]

A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41

the distance is approximately 6.4 units

Calculate the missing angle measures in each figure

dalvyx [7]

Answer:

a:36 b:30

Step-by-step explanation:

A:180-56, since it is a straight line.

180-124-20= 36

B:180-120=60

60+3x+1x=180

60+4x=180

4x=120

In a class of 50 students, everyone has either a pierced nose or a pierced ear. The professor asks everyone with a pierced nose

Tems11 [23]

Answer: 3

Step-by-step explanation:

Let E be the event of that student pierces ear and N be the event of that student pierces nose.

Given: $n(E\cup N=50)$

$n(E)=46\\\\n(N)=7$

For any two event A and B, we have

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

Similarly , $n(E\cup N)=n(E)+n(N)-n(E\cap N)$

$50=46+7-n(E\cap N)\\\\\Rightarrow\ n(E\cap N)=53-50=3$

Hence, 3 students have piercings both on their ears and their noses.
