Vertical angles are congruent, they have the same measure.
So, <7 and <5 are vertical angles. They share the same vertex, and if you were to draw a straight line between them, it would connect and bisect them both equally.
<5= 45, so <7= 45.

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?
Answers
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.

Now, x+x+(x-40)=180. Since sum of angles of a triangle
2x+(2x-40)=180
2x+2x-40=180
4x=180+40
4x=220
x=220/4
x=55
Now,they asked us vertex angle which is 40 degrees less than sum of base angles
Therefore x+x-40=vertex angle
2x-40=vertex angle
2(55)-40=vertex angle
110-40=vertex angle
Vertex angle =70 degrees

If a horses man grows 6/5 per month, how long will it take to grow 24/10 cm
Answers
Explanation :the horses mane grows 6/5 cm per month lets let x = number of monthsit is going to grow 24/10 in x months
so 6/5x (6/5 times the number of months) = 24/10divide both sides by 6/5, eliminating the 6/5 on the left side.so x = (24/10) / (6/5)...and when dividing fractions, u flip what u r dividing by, and multiply. 24/10 * 5/6 = 120/60 which reduces to 2 months. is the correct answer!

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:!
Answers
In the case of similar figures, we have the same basic shape however it is just make larger or smaller. Since this is the case, all of the angles will remain the same.
Imagine different sizes of stop signs. They are all similar and all the angles are the same. Only the lengths of the sides change.
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.
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?
Answers
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?
Answers
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.

The expression equal to 5p is Option A: p + p + p + p + p. Other options do not correctly represent the sum of five instances of p.
The correct expression that is equal to 5p is A. p + p + p + p + p. Let's break it down:
A. p + p + p + p + p adds the variable p five times, which by definition equals 5p.
B. 4p + 1 simplifies to 4p + 1, which is not equal to 5p because it includes an additional constant term.
C. p + 5 represents the variable p plus the number 5, which is not the same as multiplying p by 5.
D. p3 + p2 is a polynomial with different powers of p and does not simplify to 5p.
Therefore, option A is the correct answer.

880
Answers
In order to find this split the pool into two separate rectangular prisms.
The first one's measurements are 4ftx16ftx10ft
4*16*10 = 640
the next prism is 4ftx10ftx10ft
4*10*10 = 400
640+400= 1040 cubic feet
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.

That means x = 5. Substitute 5 into the equation for x.
f(n) = 7 - 4(5 - 1)
Subtract 5 - 1.
f(n) = 7 - 4(4)
Multiply 4 by 4.
f(n) = 7 - 16
Subtract 16 from 7.
f(n) = -9
The answer is D.
2. Since we have to find the first 4 terms, we have to solve for x = 1, 2, 3, & 4.
Multiply 1, 2, 3, and 4 by 6. We now have:
f(x) = 6 - 25 f(x) = 12 - 25 f(x) = 18 - 25 f(x) = 24 - 25
Subtract 25 from the first term: 6, 12, 18, and 24.
f(x) = -19 f(x) = -13 f(x) = -7 f(x) = -1
The answer is C.
3. Now, we have to find the first 3 terms of f(x) = 10(2)^x. So x is 1, 2, & 3.
Raise 2 to the powers of 1, 2, and 3. The equations are now:
f(x) = 10(2) f(x) = 10(4) f(x) = 10(8)
Then multiply 10 by the three terms: 2, 4, and 8.
f(x) = 20 f(x) = 40 f(x) = 80
The answer is A.
4. Find the 21st term of f(n) = 2 + 9(n - 1). Substitute 21 for n.
f(n) = 2 + 9(21 - 1)
Subtract 1 from 21.
f(n) = 2 + 9(20)
Multiply 9 by 20.
f(n) = 2 + 180
Add 2 to 180.
f(n) = 182
The answer is B.
5. Which sequence is described by f(n) = 2(3)^x-5.
This is the only one which I'm not sure how to solve. Since I don't know, I won't answer it because I don't want to give you the wrong answer to the question, sorry about that.
6. The ninth term in f(n) = 384(1/2)^n-1. Put 9 in for n & subtract 1 from 9.
f(n) = 384(1/2)^8
Raise 1/2 to the power of 8.
f(n) = 384(1/256)
Multiply 1/256 by 384.
f(n) = 384/256
Reduce the fraction & make it a mixed number.
f(n) = 1 1/2
