The 5 is in the tenths place.

Step-by-step explanation:

:)

Answer:

131.6

Step-by-step explanation:

Since the 5 in 131.572 is underlined, we need to round the number to the nearest tenth. When rounding numbers, we need to look at the digit next to the rounded digit. The digit after 5 is 7.

If the digit after that is 1-4, we round down the 5. If the digit after that is 5-9, we round up the 5. Since 7 is between 5 and 9, we round the digit 5 to 6.

Thus, the rounded number would be: 131.6

Answer:

The value of x = 4

so

Step-by-step explanation:

We know that an angle bisector bisects the angle into two equivalent angles.

When BD bisects angle ABC, it forms two equivalent angles which are:

such as

m∠ABD = m∠CBD

as

m ∠ABD = 6x-8

m∠CBD = 3x+4

so the equation becomes

m∠ABD = m∠CBD

6x-8 = 3x+4

6x - 3x = 4 + 8

3x = 12

Divide both sides by 3

x = 4

Thus, the value of x = 4

so

Answer:

radius = 4units

diameter = 8units

Step-by-step explanation:

The radius is the distance from the midpoint of a circle to any point on the side of the circle. In this case, the radius is, 4units. The diameter is twice the radius and is 8 units.

Step-by-step explanation:

Answer: y=-3/4x+2

Step-by-step explanation:

y=mx+b

y=-3/4x+b

-4=-3/4(8) +b

-4=-6+b

b=2

y=-3/4x+b

y=-3/4x+2

Answer:

The answer is: Use a calculator.

Step-by-step explanation

With the calculator you are able to do ANY problem.

Answer: There is no solution.

Step-by-step explanation:

Simplify both sides of the equation

subtract 3x from both sides

add 6 to both sides

0=10

The answer is - there are no solutions

Answer:

$5

Step-by-step explanation:

We can solve this using a system of linear equations. The equations are written like this:

3v + 9d = 75

5v + 10d = 100 (25 more than Dawn's total is 100)

V represents video games and d represents DVDs.

Let's isolate a variable, I'm going to isolate v in the first equation:

3v = -9d + 75

v = -3d + 25

Now that we isolated v we can plug it in to the second equation:

5(-3d + 25) + 10d = 100

-15d + 125 + 10d = 100

-5d + 125 = 100

-5d = -25

d = 5

Therefore, each DVD cost $5.

Check:

3v + 9(5) = 75

3v + 45 = 75

3v = 30

v = 10

5(10) + 10(5) = 100

50 + 50 = 100

100 = 100

I hope this helps!!

Answer:

-6[tex]\sqrt{7}[/tex] /434

Step-by-step explanation:

Answer:

1. H=6

2. Y= -1

3. T= 2

4. D= 2.1

5. K= 0

6. -13 1/3

Step-by-step explanation:

This means x = 2, y = 3 and z = 1

========================================================

Work Shown:

Double everything in the second equation to get 4x-2y+4z=6

Add this result to the first equation

[tex]x+2y-4z = 4\\4x-2y+4z = 6\\5x+0y+0z = 10[/tex]

The first two lines of that expression above shows us adding x+2y-4z=4 to the equation 4x-2y+4z = 6

The x terms add to x+4x = 5x

The y terms add to 2y+(-2y) = 0y

The z terms add to -4z+4z = 0z

The terms on the right hand side add to 4+6 = 10

That's how we end up with the new equation 5x+0y+0z = 10

That becomes 5x = 10 which solves to x = 2 when we divide both sides by 5.

------------------------

Use this x value in the third original equation to find z

3x-8z = -2

3(2)-8z = -2

6-8z = -2

-8z = -2-6

-8z = -8

z = -8/(-8)

z = 1

------------------------

Use the x and z values we found to find y

x+2y-4z = 4

2+2y-4(1) = 4

2+2y-4 = 4

2y-2 = 4

2y = 4+2

2y = 6

y = 6/2

y = 3

----------------------

Overall we get the solutions to be x = 2, y = 3 and z = 1

We can say the solution as an ordered triple is (x,y,z) = (2,3,1)

Answer:

Volume of right circular cone is 388.43 in³

Step-by-step explanation:

Height of circular cone = 16.8 in

Radius of circular cone = 4.7 in

We need to find Volume of right circular cone

The formula used for calculating volume of a right circular cone is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]

Putting values and finding volume

[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14\times (4.7)^2 \times \frac{16.8}{3}\\Volume=3.14\times 22.09 \times 5.6\\Volume= 388.43 \:in^3[/tex]

So, Volume of right circular cone is 388.43 in³

Answer:

The sequence of transformations are;

A translation by 1 unit left, followed by a reflection across the x-axis

Step-by-step explanation:

Here, we want to know the transformation sequence

Let us select one point

J(1,4)

to J’(0,-4)

To translate 1 unit right means that we are subtracting the value of 1 from the x-coordinate

That leaves us with (0,4)

To get the change in the y-coordinate value to negative, it means that we have reflected over the x-axis

x-axis reflection turns (x,y) to (x,-y)

So, the sequence of transformations that maps the two is;

A translation by 1 unit left followed by a reflection across the x-axis

Answer:

translation 1 unit left, then 180 degrees

Step-by-step explanation:

J (1,4)

K (6,4)

L (1,1)

Moving it 1 unit left,  x unit - 1

J (0,4)

K (5,4)

L (0,1)

Now, rotate it 180 degrees, (x,y) = (-x,-y)

J' (0,-4)

K' (-5,-4)

L' (0,-1).

Hence, the triangle JKL is transformed into triangle J'K'L' when a triangle JKL translates 1 unit to the left and then rotate 180 degrees about the origin.
