Find the distance between the points c ( 6, 5) and D(-3, 1),
svet-max [94.6K]

Answer:

see explanation

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (6, 5) and (x₂, y₂ ) = (- 3, 1)

d = \sqrt{(-3-6)^2+(1-5)^2}

  = \sqrt{(-9)^2+(-4)^2}

  = \sqrt{81+16}

  = \sqrt{97} ≈ 9.85 ( to 2 dec. places )

Please help! 9/4(7+3-4*9)
Serga [27]

Answer:

58.5

Step-by-step explanation:

This expression should be simplified using order of operations. According to order of operations or PEMDAS, complete any numbers in parenthesis then any exponents, multiplication, division, additions and subtraction moving left to right through each operation.

Begin with Parenthesis.

(7+3-4*9) - Multiply first

(7+3-36) - Then add/subtract left to right

10 - 36 = -26

Replace -26 where the parenthesis were in the original expression.

9/4 (-26)

What is 50% of 64?
Dmitriy789 [7]

Answer:

50% = 50/100 = 0.5

20% = 20/100 = 0.2

25% = 25/100 = 0.25

10% = 10/100 = 0.1

Now let's begin our calculation

50% of 64=(0.5*64)=32

20% of 55=(0.2*55)=11

25% of 16 = (0.25*16) =4

10% of 200=(0.1*200)=20

20% of 86=(0.2*86)=17.2

Step-by-step explanation:

Hope this helps <3
