Answer:

x = 4

Step-by-step explanation:

6x + 42 and 18x - 6 are alternate angles and are congruent , so

18x - 6 = 6x + 42 ( subtract 6x from both sides )

12x - 6 = 42 ( add 6 to both sides )

12x = 48 ( divide both sides by 12 )

x = 4

Answer:

A square root of 11, 3.7, square root of 20, 4.8

Step-by-step explanation:

4.8

√20 = 4.47

3.7

√11 = 3.32

In order from least to greatest,

√11, 3.7, √20, 4.8.

The correct option is A.

Putting numbers in ascending order simply means to do it from smallest to largest.

Given:

We have numbers,

4.8,

square root of 20 = 4.47,

square root of 11 = 3.32

And 3.7.

In order from least to greatest,

√11, 3.7, √20, 4.8.

Therefore, the expression is √11, 3.7, √20, 4.8.

Step-by-step explanation:

Step-by-step explanation:

1)

d² = (6-1)²+(3-1)²

or, d² = 5²+2²

or, d² = 25+4

so, d² = 29

so, d = 5.4 units

2)

d² = (4+2)²+(3-1)²

or, d² = 6²+2²

or, d² = 36 + 4

so, d² = 40

so, d = 6.3 units

3)

d² = (3-1)²+(-2-1)²

or, d² = 2²+(-3)²

or, d² = 4+9

or, d² = 13

so, d = 3.6 units

Answer: 8 & 20

Step-by-step explanation:

160=xy

x*2.5=y

x=8 y=20

Answer:

The rate of change for a line is the slope, the rise overrun, or the change in y over the change in x. The slope can be calculated from two points in a table or from the slope triangle in a graph. The slope is the parameter m in the slope=intercept form of a line: y=mx+b.

Answer:

Each box is 15.99

Step-by-step explanation:

Just the divide the total cost by 6

Answer:

Equation : b = $95.94/6

the cost per box is $15.99.

Step-by-step explanation:

For the first question, we need to create an equation to determine the cost per box. Let us assign "b" to represent the cost per box and the solution is shown below:

b= $95.94/6

95.94 divided by 6 is 15.99.

Therefore, the cost per box is $15.99.

Try this option:

1) vector AB=(2;3;6).

[tex](X_B-X_A;Y_B-Y_A;Z_B-Z_A); \ => (4-2;2+1;3+3); \ =>(2;3;6).[/tex]

2) |AC|=9.

[tex]|AC|=\sqrt{(X_C-X_A)^2+(Y_C-Y_A)^2+(Z_C-Z_A)^2}=\sqrt{(6-2)^2+(3+1)^2+(4+3)^2}=\sqrt{81}=9.[/tex]

Answer:

1.    [tex]x[/tex] = 3√10     2.  [tex]x[/tex] = 5      3.   [tex]x[/tex] = 6√2

Step-by-step explanation:

Use Intersecting Secant-Tangent Theorem:

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

1.  In this circle, DB is a tangent and DA is a secant.  They intersect at point D.

So  DB² = DC x DA

    [tex]x[/tex]² = 5 x (5 + 13)

    [tex]x[/tex]² = 90

     [tex]x[/tex] = √90 = 3√10

2.  In this circle, FE is a tangent and FH is a secant.  They intersect at point F.

So  FE² = FG x FH

      10² = [tex]x[/tex] x 20

     100 = 20[tex]x[/tex]

         [tex]x[/tex] = 5

3.  In this circle, NM is a tangent and NP is a secant.  They intersect at point N.

So  NM² = NO x NP

    [tex]x[/tex]² = 4 x (4 + 14)

    [tex]x[/tex]² = 72

     [tex]x[/tex] = √72 = 6√2

Step-by-step explanation:

The given information is 6 inches = 4 months, and that may not sound like much but we can get the answer just from that tidbit.

Cross multiply :

[tex]\frac{6 inches}{4 months}[/tex] = [tex]\frac{x}{10 months}[/tex]

4x = 60

Divide by 4 on both sides.

x = 15.

Answer:

m∠Z1 = 93°

Step-by-step explanation:

Vertical Angles are the angles opposite each other when two lines cross.

They are congruent (the same as each other).

Therefore, m∠Z1 = m∠Z2, so if  m∠Z2 = 93° then m∠Z1 = 93°

The measure of ∠1 is 93 degrees

What are vertical angles ?

Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are opposite each other and they share the same vertex point.

Vertical angles are always congruent.

Therefore, since ∠1 and ∠2 are vertically opposite angles this means they are congruent.  

Therefore,

∠1 ≅ ∠2

∠2 = 93°

∠1 = 93°

Answer:

1.   x² + y² + 8x - 14y - 35 = 0

2.  x² + y² - 2x - 8y - 47 = 0

3.  x² + y² - 4x - 2y - 116 = 0

4.  x² + y² + 2x + 4y - 20 = 0

5.  x² + y² - 4x - 8y - 52 = 0

Step-by-step explanation:

General equation of a circle is:  x² + y² + 2gx + 2fy + c = 0

with center (-g, -f) and radius √(g² + f² - c)

1.  From inspection:  center (-4, 7)  and radius = √100 = 10

   Therefore, g = 4  and  f = -7

   √(4² + (-7)² - c) = 10  ⇒  65 - c = 100  ⇒  c = -35

   So,  x² + y² + 8x - 14y - 35 = 0

2.  From inspection:  center (1, 4)  and radius = √64 = 8

   Therefore, g = -1  and  f = -4

   √((-1)² + (-4)² - c) = 8  ⇒  17 - c = 64  ⇒  c = -47

   So,  x² + y² - 2x - 8y - 47 = 0

3.  From inspection:  center (2, 1)  and radius = √(11²) = 11

   Therefore, g = -2  and  f = -1

   √((-2)² + (-1)² - c) = 11  ⇒  5 - c = 121  ⇒  c = -116

   So,  x² + y² - 4x - 2y - 116 = 0

4.  From inspection:  center (-1, -2)  and radius = √25 = 5

   Therefore, g = 1  and  f = 2

   √(1² + 2² - c) = 5  ⇒  5 - c = 25  ⇒  c = -20

   So,  x² + y² + 2x + 4y - 20 = 0

5.  From inspection:  center (2, 4)  and radius = √72

   Therefore, g = -2  and  f = -4

   √((-2)² + (-4)² - c) = √72  ⇒  20 - c = 72  ⇒  c = -52

   So,  x² + y² - 4x - 8y - 52 = 0
