Which best describes the scale factor for each
dilation?

Answer:

1,875 cm^3

Step-by-step explanation:

To find the volume of the big square you would multiply 20x5x20= 2,000

to find the volume of the little square you would multiply 5x5x5= 125

Then to find the Volume of the square with the hole in it you would subtract 2,000 and 125 which = 1,875 cm^3

Answer:

x=85

Step-by-step explanation:

The angles are vertical angles, therefore they are congruent. This means we can set them equal to each other.

x+5=90

Solve for x by isolating x. To do this, subtract 5 from both sides

x+5-5=90-5

x=85

So, x=85, and the second choice is correct.

Answer:

It is 85.

Step-by-step explanation:

The angles are vertical from each other so they are equal. 85+5=90.

Answer:

  4 cm

Step-by-step explanation:

The ratios of sides in a 30-60-90 triangle are ...

  1 : √3 : 2

The hypotenuse is double the length of the shortest side, so is 4 cm in your triangle.

Final answer:

In a 30-60-90 triangle, if the shortest side is 2 cm, the hypotenuse is twice that length, resulting in a hypotenuse of 4 cm.

Explanation:

The 30-60-90 right triangle has sides in a specific ratio. The lengths of the sides opposite the 30°, 60°, and 90° angles are in the ratio 1:√3:2. If the shortest side is 2 cm, which is opposite the 30° angle, the hypotenuse is twice the length of the shortest side because it is opposite the 90° angle. Therefore, the length of the hypotenuse is 4 cm.

Answer:

52 m

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 39^2 = 65^2

a^2 + 1521 = 4225

4225 - 1521 = 2704

Square root of 2704 = 52

Answer:

52m

Step-by-step explanation:

as this is a right angled triangle (has a 90° angle), you can use the Pythagoras theorem to work out the missing side.

Pythagoras theorem:

[tex]a^{2} + b^{2} = c^{2}[/tex]

side A squared (labeled on diagram below)

+ side B squared

= side C squared

for this example though, we don't know the length of side B so we need to swap around the formula.

[tex]c^{2} - a^{2} = b^{2}[/tex]

replace the letters for their numbers,

[tex]65^{2} - 39^{2} = b^{2}[/tex] (calculate)

[tex]65^{2} - 39^{2} = 2704[/tex]  

2704 = b² but we want b by itself so we will square root b² (2704)

[tex]\sqrt{2704} = 52[/tex]

∴ side B = 52m (remember we were calculating in meters)

I hope this was helpful :-)

Final answer:

An isosceles right triangle has two congruent angles, which are both 45 degrees. The right angle measures 90 degrees.

Explanation:

An isosceles right triangle has two congruent angles. In this type of triangle, the two legs that form the right angle are of equal length. Let's call that length 'x'. The hypotenuse, which is the side opposite the right angle, is equal to 'x' times the square root of 2. The congruent angles in an isosceles right triangle are both 45 degrees, and the right angle measures 90 degrees.

Yes. 1/10 is equal to 0.10. So 6/10 is equal to 0.60.

Answer: 9y = 2x is the constant proportionality of 9

Step-by-step explanation:

Answer:

9y = 2x is the constant proportionality of 9

Step-by-step explanation:

The mapping rule for a 90° clockwise rotation is (x, y) → (–y, –x), so R ( 2, -5) becomes (-5, -2).

Point C is the image of R.

The point C is the image of R.

Here,

Point R was rotated about the origin (0,0) by 90° clockwise.

We have to find the image of R.

What is 90 degree Clockwise rotation?

To rotate the figure 90 degrees clockwise about a point, every point (x,y) will rotate to (y, -x).

Now,

By figure;

Point R is ( 2, -5 )

Now, Point R was rotated about the origin (0,0) by 90° clockwise.

The image of point (x, y) = (y, -x)

Hence, the image of R = (-5, -2 ) = Point C

So, by graph;

Point C is image of Point R.

Answer:

12y + 11

Step-by-step explanation:

To add them you would add like terms. That means you would add those with y together and those without together.

8y + 4y + 6 + 5 = 12y + 11

If you want to solve for y, subtract 11 from both sides then divide both sides by 12.

Option C is correct, x² - 10x + 25 = 0 is the polynomial for the solution set of {5}.

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

The polynomial with a solution set of {5} for the equation

x²-5x+25=0

x is the variable of the given polynomial

We know that (a-b)²=a²+b²-2ab

x²-5x+25 can be converted to (x-5)²

(x-5)² = 0

Expanding the square, we get:

x² - 10x + 25 = 0

Hence, x² - 10x + 25 = 0 is the polynomial for the solution set of {5}.

Approximately: 9.63

Step-by-step explanation:

Answer:

1.48 2.100

Step-by-step explanation:

To find out how many trees grew 10 or more inches, you should look at the '10 or more inches' section of the histogram and check the frequency, which represents the tree count. To find the total number of trees represented, you should add up the frequencies of all growth rate sections.

To determine how many trees measured grew 10 or more inches over the year, you need to look at the histogram for the section that represents 10 or more inches. The y-axis of a histogram indicates frequency, which in this case, means the number of trees. Count the number of instances within the section for 10 or more inches. The total number of trees represented in the histogram can be found by adding the frequency (tree counts) for each section which corresponds to tree growth rates.

For example, if the '10 or more inches' section shows a frequency of 20, it means 20 trees grew 10 or more inches over the year. If the frequencies corresponding to all growth rates total up to 50, it means the histogram represents 50 trees.

Answer:

400

Step-by-step explanation:

Is means equals and of means multiply

68 = 17% * what number

Change to decimal form

68 = .17 * what number

Divide each side by .17

68/.17 = .17/.17 what number

400 = what number

The number is 400

68 is approximately 17 percent of 400.

To find out what number 68 is 17% of, we can use the following formula:

(17 / 100) x = 68

Let's solve for x:

(17 / 100) x = 68

To isolate x, we can multiply both sides of the equation by (100 / 17):

x = (68 × 100) / 17

x ≈ 400

Therefore, 68 is approximately 17% of 400.

To understand this calculation, think of the percentage as a proportion or ratio. In this case, we are trying to find the ratio of 68 to the unknown number. The result, 0.17, represents how much of the unknown number 68 comprises. By multiplying this ratio by the unknown number, we obtain the value of x, which is approximately 400. Thus, 68 is roughly 17% of 400, indicating that 68 represents 17% of the value 400.
