If two similar rectangles have corresponding sides with a ratio of 2:3, what is the
ratio of their areas?
Answer:
4:9 ratio
Step-by-step explanation:
We know that the sides cannot be the same because it is a rectangle, therefore there is a width and length.
For the width, which is the shortest side, we will keep the radius as it is, that is, for rectangle 1 it will be 2 and for rectangle 2 it will be 3.
For the length, which is the longest side, we multiply the radius by two, which means that rectangle 1 will be 4 (2 * 2) and for rectangle 2 it would be 6 (2 * 3)
If we calculate the area it would be:
rectangle 1:
2 * 4 = 8
rectangle 2:
3 * 6 = 18
Which means that the radius is 8/18 = 4/9
What is a 4: 9 ratio
Solving systems of equations algebraically.
y = -5
5x + 4y= -20
And SHOW YOUR WORK PLEASE!!!!
Step-by-step explanation:
If y = - 5
Then put value of y
5x + 4(-5) = - 20
5x - 20 = - 20
5x = - 20 + 20
5x = 0
x = 0
Answer:
x = 0
y = -5
Step-by-step explanation:
Since you already have the value of y, all you need to do is plug it into the equation, like so:
5x + 4y = -20
5x + 4(-5) = -20
5x - 20 = -20
Add 20 to both sides:
5x - 20 = -20
+ 20 + 20
___________
5x = 0
Finally, divide both sides by 5:
5x = 0
x = 0
So now you have, x = 0 and y = -5

What should be the first step in adding these equations to illuminate y? 3x+4y=8 + 6x-2y=9
A. Multiply the top equation by two
B. Multiply the top equation by six
C. Multiply the bottom equation by three
D. Multiply the bottom equation by two
Answer:
D
Step-by-step explanation:
In this problem, we are adding the two equations and we want to get rid of y. To do this, we want one positive y and one negative y with the same coefficient because when we add the equations they will cancel each other out. The coefficient of the first equation's y is 4, so we want the second to be -4. The coefficient of the second equation's y is -2, and if we want it to be -4 we multiply it by -4/-2= 2, which is D. Once you do that you will get 4y and -4y in the first and second equations respectively and then you can add them to eliminate y!

What is a rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length.
The perimeter of a rectangle is defined as the total distance covered by the outer boundary of the rectangle. It is measured in unit length. The formula of perimeter is given by:
Perimeter, P = 2 (Length + Width)
The area of the rectangle is the area covered by its outer boundaries. It is equal to the product of length and width.
The formula of area of rectangle is:
Area = Length × Width unit²
Given,
Length of the plywood (L) = 6 feet
Perimeter of Plywood (P)= 22 feet
Area of Plywood = ?
Perimeter = 2(Length + Width)
22 feet = 2 (6feet + Width)
Width (W) = (22 /2 - 6) feet
Width (W) = (11 - 6) feet
Width (W) = 5 feet
Area of the plywood (A) = Length × Width
Area = 6feet × 5feet
Area = 30 feet²
Hence, Area of the plywood (A) = 30 feet²

The eighth grade class is planning a trip to Washington DC this spring. They need a minimum of 75 people to attend in order to reserve buses. If 1/3 of the eighth grade class 17 parent chaperones have signed up and this is enough to satisfy the requirement, how many students must be in the eighth grade class?
By setting up an equation and solving for the number of students in the eighth grade class, we find that there must be 174 students to meet the requirement of 75 people including 17 parent chaperones.
To find the number of students in the eighth grade class for the trip to Washington DC, let's use the information provided that 1/3 of the class plus 17 parent chaperones are just enough to satisfy the requirement of 75 people for the trip. We can set up an equation to solve for the total number of students (S) in the class:
1/3 * S + 17 = 75
First, subtract 17 from both sides of the equation:
1/3 * S = 75 - 17
1/3 * S = 58
Then, multiply both sides by 3 to find the total number of students (S):
S = 58 * 3
S = 174
Thus, there must be 174 students in the eighth grade class.
Garrett throws a dart at a circular dartboard. The dartboard has a radius of 18 inches, and the bull’s eye in the center of the dartboard has a radius of 4 inches. What is the probability that a dart thrown at random within the dartboard will hit the bull’s eye? Round your answer to the nearest tenth, if necessary.
A. 20.3%
B. 4.9%
C. 22.2%
D. 4.5%
Answer:option b. 4.9%
Explanation:
1) The probability that a dart thrown at random within the dart board will hit the bull's eye is equal to the ratio of the areas:
probability = area of the bull's eye / aera of the dart board.
2) Area of the dart board = π × (radius)² = π × (18 in)²
3) Area of the bull's eye = π × (radius)² = π × (4 in)²
4) So, the probaility is:
π (4 in)² 4²
--------------- = ------- = 0.0494
π (18 in)² 18²
The correct answer is option B)4.9
What is the probability that a dart thrown at random within the dartboard will hit the bull’s eye?
1) The probability that a dart is thrown at random within the dartboard will hit the bull's eye is equal to the ratio of the areas:
probability = area of the bull's eye/area of the dart board.
2) Area of the dart board = π × (radius)² = π × (18 in)
3) Area of the bull's eye = π × (radius)² = π × (4 in)²
4) So, the probability is:
π (4 in)² / π (18 in)² = 4² / 18² = 0.0494
What is probability?
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes and how likely they are.

MARK AS BRAINLIEST!!!!!!!!!!!!
To evaluate f(3) for the function f(x)=-2x^2+5x-9, you substitute 3 for x in the equation and simplify the expression to get the result, which is -12.
Replace x with 3: f(3)=-2(3)2+5(3)-9.
Simplify the squares: f(3)=-2(9)+5(3)-9.
Multiply through: f(3)=-18+15-9.
Combine the terms: f(3)=-3-9.
Final result: f(3)=-12.
Therefore, the evaluated result for f(3) is -12.

Which best describes the shape of this distribution?
A. Unimodal symmetric
B. Unimodal skewed
C. Bimodal symmetric
D. Uniform
E. Bimodal skewed
Answer:
Unimodal Skewed
Step-by-step explanation:
The best describes the shape of this distribution is E. Bimodal skewed
What is Bimodal skewed?If a histogram has one hump, it is unimodal; if it has two humps, it is bimodal; and if it has many humps, it is multimodal.
If a histogram is not symmetric, this will refer to as skewed.
It is positively skewed if the upper tail is longer than the lower tail.
It can have multiple peaks or be bimodal (two peaks) (or many peaks).
But a single distribution with two peaks characterizes a bimodal distribution.
This will appear as two separate bell curve shapes contained within two normal distributions on a graph that is displayed side by side.
We are given graph has 2 humps, we can conclude that the given distribution is Bimodal skewed.
Therefore, the given distribution is (E) Bimodal skewed as the distribution has 2 humps.

Express in scientific notation. 65
Final answer:
The number 65 can be expressed in scientific notation as 6.5 × 10¹, where the original decimal was moved one place to the left.
Explanation:
To express the number 65 in scientific notation, we need to write it as a product of a number between 1 and 10 and a power of 10. Since 65 is a relatively small number, we will have only one digit to the left of the decimal point. We write 65 as 6.5 × 10¹, because we have moved the decimal one place to the left to get the number 6.5, which is between 1 and 10. The exponent on the 10 is positive because the original number was greater than 1.
In sciences like chemistry, scientific notation is frequently used to express large or small quantities. This is also helpful when entering data into a calculator; it's important to know the correct procedure for your particular calculator model. In case of uncertainty, consulting an instructor is advised.
3. Triangle ABC has angle measures as shown.
(x + 2)
(6x + 10)
(a) What is the value of x? Show your work.
(b) What is the measure of angle B? Show your work.
Answer:
Below in bold.
Step-by-step explanation:
(a) The angles in a triangle add up to 180 degrees, so:
x + x + 2 + 6x + 10 = 180
8x + 12 = 180
8x = 168
x = 168/8 = 21 degrees.
(b) Angle B = x + 2
= 21 + 2 = 23 degrees.

On a coordinate plane, triangle A prime B prime C prime has points (negative 12, 12), (12, 12), (12, negative 12).
Answer:
A
Step-by-step explanation:
The coordinates of the triangle showing a dilation with a scale factor of 1/3 is (-2, 2), (2, 2) and (2, -2)
What is dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
Given that, on a coordinate plane, triangle A B C has points (-6, 6), (6, 6), (6, -6). It is being dilated with a scale factor of 1/3
Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
Here, we will consider the coordinates in place of dimensions,
Therefore,
Scale factor = coordinates of new figure / coordinates of original figure
Considering the first option = A'(-2, 2), B'(2, 2) and C'(2, -2)
Scale factor = A/A' = 2/6 = 1/3
Hence, the coordinates of the triangle showing a dilation with a scale factor of 1/3 is (-2, 2), (2, 2) and (2, -2)

(9x-8)+(x+10)+(x+2)=180 find x
Answer:
x = 16
Step-by-step explanation:
Simplifying
(9x + -8) + (x + 10) + (x + 2) = 180
Reorder the terms:
(-8 + 9x) + (x + 10) + (x + 2) = 180
Remove parenthesis around (-8 + 9x)
-8 + 9x + (x + 10) + (x + 2) = 180
Reorder the terms:
-8 + 9x + (10 + x) + (x + 2) = 180
Remove parenthesis around (10 + x)
-8 + 9x + 10 + x + (x + 2) = 180
Reorder the terms:
-8 + 9x + 10 + x + (2 + x) = 180
Remove parenthesis around (2 + x)
-8 + 9x + 10 + x + 2 + x = 180
Reorder the terms:
-8 + 10 + 2 + 9x + x + x = 180
Combine like terms: -8 + 10 = 2
2 + 2 + 9x + x + x = 180
Combine like terms: 2 + 2 = 4
4 + 9x + x + x = 180
Combine like terms: 9x + x = 10x
4 + 10x + x = 180
Combine like terms: 10x + x = 11x
4 + 11x = 180
Solving
4 + 11x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 11x = 180 + -4
Combine like terms: 4 + -4 = 0
0 + 11x = 180 + -4
11x = 180 + -4
Combine like terms: 180 + -4 = 176
11x = 176
Divide each side by '11'.
x = 16
Simplifying
x = 16
Your answer would be x = 16.
To find the answer you need to collect like terms on the left hand side by adding the x-terms and the numbers, and then solving for x.
9x + x + x = 11x
-8 + 10 + 2 = 4
11x + 4 = 180
- 4
11x = 176
÷ 11
x = 16
