two triangles are similar, and the ratio of the lengths of each pair of corresponding sides is 2:1. which statement regarding the two triangles is NOT True?
A- Their corresponding angles have a ratio of 2:!
B- Their areas have a ratio of 4:1
C- Their perimeters have a ratio of 2:!
D- Their altitudes have a ratio of 2:!
All statements are true. Ratio of corresponding angles, areas, perimeters, and altitudes is 2:1. No false statement exists.
To determine which statement regarding the two triangles is NOT true, let's analyze each option step by step.
Given:
- Two triangles are similar.
- The ratio of the lengths of each pair of corresponding sides is 2:1.
Let's denote the lengths of corresponding sides in the first triangle as [tex]\( a \)[/tex], [tex]\( b \)[/tex], and [tex]\( c \)[/tex], and in the second triangle as [tex]\( 2a \)[/tex], [tex]\( 2b \)[/tex], and [tex]\( 2c \),[/tex] respectively.
A. Their corresponding angles have a ratio of 2:1.
- This statement is true because corresponding angles in similar triangles are congruent, so their ratios would indeed be 2:1.
B. Their areas have a ratio of 4:1.
- The area of a triangle is proportional to the square of the length of its sides. So if the ratio of the lengths of corresponding sides is 2:1, the ratio of their areas would be [tex]\( (2:1)^2 = 4:1 \)[/tex]. Hence, this statement is also true.
C. Their perimeters have a ratio of 2:1.
- The perimeters of triangles are directly proportional to the lengths of their sides. Since the ratio of the lengths of corresponding sides is 2:1, the ratio of their perimeters would indeed be 2:1. So, this statement is also true.
D. Their altitudes have a ratio of 2:1.
- The ratio of the altitudes of two similar triangles is equal to the ratio of their corresponding sides. So, if the ratio of corresponding sides is 2:1, the ratio of their altitudes would also be 2:1. Therefore, this statement is true.
Since all the statements are true, the correct answer is NONE.

Community center has an L shaped swimming pool that is 10 feet deep. What is the volume of the pool
1200
1040
640
880
The total volume of pool is:
1040 cubic ft.
Step-by-step explanation:We know that the total volume of the pool is the sum of the volume of two rectangular prism.
one is a rectangular prism with dimensions 20ft.×10ft.×4ft.and the other rectangular prism has dimensions: 6ft.×4ft.×10ft.Hence, the volume of first rectangular prism is:
20×10×4=800 cubic ft.
Volume of second rectangular prism is:
6×4×10=240 cubic ft.
Hence, total volume of pool is:
800+240=1040 cubic ft.
a rectangular deck has a area of 320 ft squared. the length of the desk is 4 feet longer than the width. find the dimensions of the desk. Solve by completing the square.
Sally decided to look at new and used vans. Sally found a used van for $14000. A new van is $20000, so what percent of the price of a new van does Sally pay for a used van?
Final answer:
Sally pays 70% of the price of a new van for a used van, which is calculated by dividing the price of the used van by the price of the new van and multiplying by 100.
Explanation:
To determine what percent of the price of a new van Sally pays for a used van, we use the formula for percentage: (Part / Whole) × 100. In this case, the price of the used van ($14,000) is the part, and the price of the new van ($20,000) is the whole. Hence, the calculation will be ($14,000 / $20,000) × 100.
Performing the calculation, we get: (14,000 / 20,000) × 100 = 0.7 × 100 = 70%.Therefore, Sally pays 70% of the price of a new van for a used van.

Suppose you have to use right-triangle trigonometry to find the apothem of a regular polygon. Which is greater, the apothem or the radius of the polygon?
In a regular polygon, the apothem is the distance from the center to the midpoint of a side, whereas the radius is the distance from the center to a vertex. Because the radius is the hypotenuse in a right triangle formed within the polygon, as per the Pythagorean theorem, it is always longer than the apothem.
Explanation:In the context of a regular polygon, the apothem is defined as the distance from the center of the polygon to the midpoint of any side. The radius, on the other hand, is defined as the distance from the center to any of the vertices. Since a regular polygon's sides and angles are equal, one can observe that its apothem is always smaller than its radius.
In order to illustrate this, consider a right triangle formed by the radius, the apothem, and half the length of a side. By using the Pythagorean theorem (a² + b² = c²), we know that the radius (or hypotenuse) is the longest side, and therefore greater than the apothem (one of the perpendicular sides).
Simply put, the radius is always greater than the apothem in a regular polygon.

The radius of a regular polygon is always greater than the apothem.
To determine if the apothem or the radius of a regular polygon is greater, we can use a right-triangle trigonometry approach. Here's a step-by-step explanation:
Consider a regular polygon with n sides inscribed in a circle. The circle's radius is r, and this radius is the hypotenuse of a right triangle formed by the radius, the apothem a, and half the length of one side of the polygon.The apothem is the perpendicular distance from the center of the polygon to the midpoint of one of its sides.Since the hypotenuse of a right triangle is always the longest side, the radius (r) is always greater than the apothem (a) according to the Pythagorean theorem.For example, in a regular hexagon, the radius is twice the apothem, clearly illustrating this relationship.Therefore, in any regular polygon, the apothem is always less than the radius, as the hypotenuse (radius) is the longest side in the right triangle formed by the apothem and half the length of a side of the polygon.

A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minutes this month. Which inequality can be used to determine how many more minutes Tom can use this month without going over the 500-minute limit?
Answer:
x + 230 ≤ 500
Step-by-step explanation:
Given,
The time for which Tom used the phone = 230 minutes,
Let he further used the mobile for x minutes,
So, the total time for which he used the phone = ( x + 230 ) minutes,
According to the question,
For the extra minutes more than 500 minutes, the mobile phone carrier charges an extra fee,
Thus, if he wants to use the phone, without going over the 500-minute limit,
Then, the total time used by him ≤ 500 minutes,
⇒ x + 230 ≤ 500
Which is the required inequality.

Do Not Have Birds 25 35 60
Total 43 57 100
How many more students have rabbits than birds?
3
7
22
25
Answer:
3
Step-by-step explanation:
There are a total of 18+22 = 40 people with birds. There are a total of 18+25 = 43 people with rabbits.
This is a difference of 43-40 = 3 people.
There are 3 more students have rabbits than birds
