the radius of a circular Frisbee is 9.8 cm. Using rounding to the nearest whole number, what is an estimate for the circumference of this circle?

Answer:

Question 1: [tex]x=4[/tex]

Question 2: [tex]x= \pm7[/tex]

Question 5: The dimensions of one face of the container are 6 by 6 inches.

Step-by-step explanation:

Hi there!

Question 1

[tex]x^3=64[/tex]

Rewrite 64 as a power of 3:

[tex]x^3=4^3[/tex]

(We could find that 4³ = 64 through trial and error)

This above equation makes it true that x=4. If aⁿ = bⁿ, then a=b:

[tex]x=4[/tex]

Question 2

[tex]x^2=49[/tex]

Rewrite 49 as a power of 2:

[tex]x^2=7^2[/tex]

Again, we could have found this through trial and error, or by looking at our multiplication tables.

[tex]x=7[/tex]

However, remember that positive and negative numbers will all square to be a positive number. So, therefore, x can be -7 OR 7 (since both, when squared, equal 49):

[tex]x= \pm7[/tex]

Question 5

Let x be equal to the length of one edge of the cube.

Volume of a cube formula: [tex]V=x^3[/tex]

Plug in the given information, when V is the volume:

[tex]216=x^3[/tex]

Rewrite 216 as a power of 3:

[tex]6^3=x^3[/tex]

^ We could have found this through trial and error.

[tex]x=6[/tex]

Therefore, the dimensions of one face of the container are 6 by 6 inches.

I hope this helps!

The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles

Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.

Since the angles are supplementary, hence the required expression will be:

m∠10 + m∠14 = 180

Given that m∠10 = 70 degrees

70 + m∠14 = 180

m∠14 = 180 - 70

m∠14 = 110 degrees

Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

Answer:

2,786

Step-by-step explanation:

You can make this easier by taking the expanded form of 398:

300 + 90 + 8

7 x 300 = 2100

7 x 90 = 630

7 x 8 = 56

Then add all these values together:

2100 + 630 + 56 = 2,786

Answer:

[tex]x=61[/tex]

Step-by-step explanation:

We can find the angle directly above the [tex]2x+8[/tex].

We know that because they both lie on a straight line, the other angle is [tex]180-(2x+8)=172-2x[/tex].

Aha! We have a path to the solution!

[tex]172-2x=x-11[/tex] because of the parallel line angle theorem(I forget what it's called).

We then add [tex]2x[/tex] and [tex]11[/tex] to both sides to get [tex]183=3x[/tex].

Lastly, we divide by [tex]3[/tex] to get [tex]61=x[/tex].

So, [tex]\boxed{x=61}[/tex] and we're done!

Answer:

The HCF of 72 and 56 is 8

and, the LCM is 504

Answer:

Length = 30

Width = 5

Step-by-step explanation:

So the formula for perimeter is

P = 2L+2W

And we know that:

L = 6W

So then we put in all the information that we do know

70 = 2(6W)+2W

And pop that into a calculator and you get W=5

So now we put that information into L = 6W to get:

L = 6×5

L = 30

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Find the side length of the square. The formula is for area is

[tex]a = {s}^{2} [/tex]

So take the square root to find the side length.

[tex] \sqrt{121} = \sqrt{ {s}^{2} } [/tex]

[tex]s = 11[/tex]

Now find the perimeter of the square.

[tex]11 \times 4 = 44[/tex]

setup the equation to solve for x. The left side is the perimeter of the rectangle and the right is the perimeter of the square.

[tex]3x + 3x + x - 2 + x - 2 = 44[/tex]

Collect like terms

[tex]8x - 4 = 44[/tex]

subtract 4 from both side

[tex]8x = 40[/tex]

divide both side by 8

[tex]x = 5[/tex]

each point of the given figure has to be changed from (x, y) to (-y, x)

Step-by-step explanation:

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.

Example 1 :  

Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. If this triangle is rotated 90° counterclockwise, find the vertices of the rotated figure and graph.

Solution :  

Step 1 :

Here, triangle is rotated 90° counterclockwise. So the rule that we have to apply here is

(x, y) -------> (-y, x)

Step 2 :

Based on the rule given in step 1, we have to find the vertices of the rotated figure.

Step 3 :

(x , y) -----> (-y , x)

F(-4 , -2) -------> F'(2, -4)

G(-2, -2) -------> G'(2, -2)

H (-3, 1) -------> H'(-1, -3)

Step 4 :

Vertices of the rotated figure are        

F'(2, -4), G'(2, -2) and H'(-1, -3)

The adjacent sides of rectangle form 90° to each other or are

perpendicular, while the opposite sides are parallel.

The error, is that the coefficient of x, in the four equations can only take on two values, such that if one of the values is m, the other will be [tex]-\dfrac{1}{m}[/tex]

Reasons:

In a rectangle, the adjacent sides are perpendicular to each other, while

the opposite sides are parallel.

The slope of parallel lines are equal, and the slope, of a line perpendicular to another line with slope, m, is [tex]-\dfrac{1}{m}[/tex], therefore the slopes of the parallel sides should be equal, which gives;

8x² - 24 = 8 (x² - 3)

Answer:

To put this equation in point slope form, we want an equation of the form y=mx+b or in this case, y< mx+b or y< mx+b. To isolate y, we divide through by 2 and move the 5/2 to the other side, so the equation becomes 3x+5/2 > y. So, since we are interested in all values of y that are less that 3x+5/2 we would shade the region below the line. Since y=3x+5/2 is not a solution to the inequality since it is strictly less, we would need a dashed boundary line since the boundary is not included.
