Mathematics

White raven [17]3 years ago
6 0

Answer:

Step-by-step explanation:

The diameter of the circle is the length of a line going through the middle from one side to the other.

The radius is the length of a line going from the middle of a cricle to the side.

So, the radius is half of the diameter.

62.8÷2=31.4

The radius is 31.4 cm.

Find the magnitude of wx for w(6 -3 6) and x(6 3 4)<br> A. 2sqrt10<br> B. 35<br> C. 4sqrt2<br> D. 32
gladu [14]

Answer:

|WX|=2\sqrt{10}

Step-by-step explanation:

To find the distance between two points in there dimensional coordinate system, we use the formula;

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}

The magnitude for  w(6 ,-3 , 6)  and x(6, 3, 4)

|WX|=\sqrt{(6-6)^2+(3--3)^2+(4-6)^2}

|WX|=\sqrt{(0)^2+(6)^2+(-2)^2}

|WX|=\sqrt{0+36+4}

|WX|=\sqrt{40}

|WX|=2\sqrt{10}

The correct choice is A.

The decimal i am thinking of is 3 hundredths less than 3 tenths. What is my decimal
Alinara [238K]

3 hundredths - 3/100

3 tenths - 3/10

3/10 is the same as 30/100

3/100 less than 30/100 is 30/100-3/100 = 27/100

Answer: 27/100

What is the equation of the line that is parallel to the given line and passes through the point (12, −2)? y = –Six-fifths x + 1
lapo4ka [179]

Answer:

y = Five-sixths x – 12

Step-by-step explanation:

In the picture attached, the given line is shown. Its slope is:

m = [6 - (-4)]/[12 - 0] = 5/6

The line that is parallel to the given line has the same slope.

A line with slope m that pass through (x1, y1) satisfies:

y - y1 = m(x - x1)

Replacing with m = 5/6 and point (12, -2):

y - (-2) = 5/6(x - 12)

y + 2 = 5/6x - 10

y = 5/6x - 10 - 2

y = 5/6x - 12

How do I solve 1/10x+5=-3x-13+4x ?
Temka [501]

Answer:

x = 20

I am not sure if you wanted the answer. Sorry!

Step-by-step explanation:

Let's solve your equation step-by-step.

1/10 x + 5 = - 3x - 13 + 4x

Step 1: Simplify both sides of the equation.

1/10 x + 5 = - 3x - 13 + 4x

1/10 x + 5 = - 3x + - 13 + 4x

1/10 x + 5 = (<em>- 3x + 4x</em>) + (- 13)

1/10 x + 5 = <em>x</em> + - 13

1/10 x + 5 = x - 13

Step 2: Subtract x from both sides.

1/10 x + 5 - <em>x </em>= x - 13 - <em>x</em>

- 9/10 x + 5 = - 13

Step 3: Subtract 5 from both sides

- 9/10 x + 5 - <em>5</em> = - 13 - <em>5</em>

- 9/10 x = - 18

Step 4: Multiply both sides by 10/(- 9).

(<em>10/ - 9</em>) * (- 9/10 x) = (<em>01/ - 9</em>) * (- 18)

x = 20

Hope this helps!
