In the diagram, ∠4 ≅ ∠5 and SE — bisects
∠RSF. Find m∠1. Explain your reasoning.
Answers
Answer:
60°
Step-by-step explanation:
You want the measure of angle 1 in the given diagram.
Angle relationsTransversal TR creates corresponding angles 1 and 5, so those are congruent.
It is given that angles 4 and 5 are congruent.
Transversal SE creates alternate interior angles 2 and 4, so those are congruent.
Angle bisector SE creates angles 2 and 3 congruent.
Now we have ∠1≅∠5≅∠4≅∠2≅∠3.
Hence all of the angles are congruent to each other, and angle 1 is 1/3 of 180°.
m∠1 = 60°
A state seal, which is round, hangs in the capitol building. It has a radius of 2 yards. What is the seal's diameter?
Answers
Step-by-step explanation:
you do understand that the diameter of a circle is simply 2 times the radius, yes ?
imagine a circle and you draw a radius line (from the center of the circle to the circle arc).
and now imagine to draw another radius line, just in the opposite direction.
when you look at the result, you have 1 straight line going from the circle arc to the circle arc and passing through the center of the circle. that is what a diameter is.
how long is it ? well, we drew 2 radius lines to create this line. so, it is 2×radius long.
so, the diameter of the seal is
2×2 = 4 yards
Find an explicit formula for the following equence, an which tart with a1=23. 23,34,45,56,…

The explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11. Here the first term is a1 = 23 and the common difference is d = 11.
What is the explicit formula for an arithmetic sequence?The explicit formula for an arithmetic sequence gives the nth term of the sequence. I.e.,
aₙ = a1 + (n - 1)d
Here a1 is the first term; d is a common difference, it is calculated by
d = aₙ₊₁ - aₙ = aₙ₋₁ - aₙ
Calculation:The given sequence is 23, 34, 45, 56,...
Here the first term a1 = 23
So, the common difference between the terms in the sequence is
d = 34 - 23 = 11
Then, the explicit formula for the given sequence is
aₙ = a1 + (n - 1)d
⇒ aₙ = 23 + (n - 1)11
Therefore, the nth term of the explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11.

Assuming timmy completes all chores, the number of dollars timmy will have 7 weeks after his birthday is 85 dollars.
What are equations?In mathematics, an equation is a claim that two expressions are equivalent. It is a mathematical expression that employs the equals symbol, "=", to indicate that two quantities have values that are equal. Problems in algebra, geometry, calculus, and other branches of mathematics are frequently solved using equations. In algebra, equations are frequently used to depict the connection between variables and constants, as well as to discover the value of an unknown variable. For example, the equation x + 2 = 5 may be utilised to get the value of x, which is 3. Equations can be linear, quadratic, or higher-degree, and they can involve multiple variables.
How to solve?
Let x be the number of weeks after Timmy's birthday.
The total number of dollars Timmy will have after x weeks is 50 + 5x.
Therefore, Timmy will have 50 + 5(7) =85 dollars after 7 weeks

the initial population of a town is 100,231 and it grows with a doubling time of 98 years. what will the population be in 31 years?
Answers
If the initial population of a town is 100,231 and it grows with a doubling time of 98 years, the population after 31 years is 124803
The initial population of the town = 100231 people
The doubling time = 98 years
We have to find the population in 31 year
The exponential function will be
f(t) = fo(2)^(t/98)
f(t) is the population of the town in t years
fo is the population of the town in t = 0 years
t is the number of years
2 because it doubling time
The value of t = 31 years
Substitute the values in the function
f(31) = 100231×(2)^(31/98)
Do the arithmetic operations
f(31) = 100231 × 1.245
f(31) = 124803.23
f(31) ≈ 124803
Therefore, the population after 31 years is 124803

A model car is 12 inches long. Using a scale of 3 inches : 4 feet ,how long is the actual car
Answers
The basic unit of length in the metric system is the meter. All units of length in the metric system are derived from the meter.
What is unit of length?Using measuring instruments like a ruler, measuring tape, etc., one can measure the length of any object. A ruler can be used to determine, for instance, how many inches a pencil is long. A feet scale can be used to gauge the height of each student in a class.The inch, foot, yard, and mile are the fundamental units of length and distance measurement in the English system. The rod, furlong, and chain are additional length units.Length of the car is 12 inches equal to 192 feet.
Given ,
3 inches : 4 feet
3 inches : 4*12
3 inches :48
1 inches : 16 feet
Length of the car is 12 inches = 12 * 16
Length of the car is 12 inches = 192 feet
The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For instance, a rectangle's length and width are its dimensions.In the metric system, the SI unit of length is a metre which is defined as: “The length of the path travelled by light in a vacuum within 1⁄299792458 seconds.”The SI unit of length is a metre (m). One metre (m) is divided into 100 equal parts called centimetre (cm). One centimetre (cm) has 10 equal parts called millimetre (mm).

The circumference of a circle is 11π cm. What is the area, in square centimeters? Express your answer in terms of π.
Answers
Answer:
The area of the circle is 30.25π cm^2.
Step-by-step explanation:
The circumference of a circle is equal to the diameter of the circle times π. Therefore, if the circumference of the circle is 11π cm, the diameter must be 11 cm.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. The radius of the circle is half the diameter, so the radius is (1/2) * 11 cm = 5.5 cm.
Substituting this value for r into the formula for the area of a circle, we get:
A = π * (5.5 cm)^2
= π * 30.25 cm^2
= 30.25π cm^2
Therefore, the area of the circle is 30.25π cm^2.

Answers
The account statement for Account B is incorrect.
What is simple rate of interest?
Simple rate of interest is a type of interest calculation where interest is calculated only on the principal amount of a loan. Simple interest is calculated periodically, usually monthly or annually, as a fixed percentage of the principal. It is different from compound interest, which applies interest to both the principal and the accumulated interest. It is simpler to calculate than compound interest, and is generally used for short-term loans.
Given: Account A: $100, 3.4% and Account B: $300, 1.8%
We know, Simple Interest = Principal × Rate × Time
Interest for Account B = $300 × 1.8%
= $5.40

Answers
In this scenario, Roy and Travis are traveling towards each other on a highway between Dallas and Pecos. Roy is located 30 miles from Dallas and Travis is located in Pecos. They both plan to meet along the highway to exchange the key to a treasure chest. The distance from Dallas, d, is a function of the number of hours, h, since Travis left Pecos. This means that the distance from Dallas will change based on the number of hours that have passed since Travis left Pecos.
The point (4, 270) represents a specific point on the distance from Dallas versus hours since Travis left Pecos graph. It indicates that after 4 hours since Travis left Pecos, the distance from Dallas is 270 miles. This means that at this point in time, Roy and Travis are both located 270 miles from Dallas and are traveling towards each other on the highway.
