What is the measure of angle 1, angle 5, angle 2, angle 8, and angle 7? Angle 4 = 72 degrees.
Answers
The unknow angles are as follows:
m∠1 = 108 degreesm∠2 = 72 degreesm∠5 = 108 degrees.m∠7 = 108 degreesm∠8 = 72 degreesHow to find angles in parallel lines?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
Therefore,
m∠4 = 72 degrees
Hence,
m∠1 + m∠4 = 180 (angle on a straight line)
m∠1 = 180 - 72
m∠1 = 108 degrees
m∠2 = m∠4 (vertically opposite angles)
Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.
Therefore,
m∠2 = 72 degrees
m∠5 = m∠1 (corresponding angles)
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.
m∠5 = 108 degrees.
m∠7 = m∠5(vertically opposite angles)
m∠7 = 108 degrees
m∠8 = m∠2 (alternate exterior angles)
Alternate exterior angles are congruent.
m∠8 = 72 degrees

The four algebra classes at sanchez school are going on a field trip to a museum. each class contains s students. the museum charges $8 per student for admission. there is also a flat fee of $200 for the buses. a. write an expression for the total cost of the buses and the museum admission fees for all four classes. b. write a rational expression for the cost per student. simplify the expression as much as possible. c. use the expression you wrote in part (b) to find the cost per student if each class has 20 students.
Answers
a)The expression for the total cost for all four classes can be given as 32s + 200. b) the rational expression for the cost per student is 2(4s+25)/s c) if each class has 20 students then the cost per student is equal to $10.50.
a) Total cost expression can be determined as follows:
total fees of admission + fees of bus = total cost
total cost = (4s × 8) + 200
total cost = 32s + 200
b) A rational expression to determine the cost per student can be calculated as follows:
cost per student = total cost ÷ the total number of students
cost per student = 32s + 200 ÷ 4s
We now factor the numerator by using its GCF;
cost per student = 4 × 2 (4s + 25) / 4×s
cost per student =2 (4s + 25) / s
c) Now using this expression we can find the cost per student if each class has 20 students;
cost per student = 2 (4s + 25) / s
cost per student = 2 ( 4×20 + 25)/ 20
cost per student = 2 ( 80 + 25) / 20
cost per student = 2 (105) / 20
cost per student = 210 / 20 = $10.50

the number of women graduating from 4-yr colleges in a particular country grew from 1930, when 48780 women earned a bachelor's degree, to 2003, when approximately 756000 women received such a degree. find an exponential function that fits the data, and the exponential growth rate.
Answers
The exponential function which shows the exponential growth rate of graduating women is: A(t) = A₀e∧(0.037t).
What is defined as the Growth Function?When we need to start writing a growth function, we use three separate components. The first component is the starting population, the second is the growth rate, and also the third is the time elapsed. By combining all three, we can create a growth equation that will assist us in determining the growth rate if we are provided with the final population as well as the time elapsed.The following equation can be used to calculate an exponential function again for number of women graduating from four-year colleges in t years after 1930:
A(t) = A₀e∧(rt)
In which A₀ is the starting point and r is the exponential growth rate expressed as a decimal.
In 1930, 48780 women received a bachelor's degree.
This implies that;
A₀ = 48780
In 2004, approximately 756000 people
The year 2003 is 73 years after 1930, that also means
Using the equation as an example:
A(t) = A₀e∧(rt)
Put the values;
756000 = 48780 e∧(73r)
e∧(73r) = 756000/ 48780
e∧(73r) = 15.49
Taking log both side;
73r = ㏑ 15.49
r = 2.7/7
r = 0.037
The function becomes;
A(t) = A₀e∧(0.037t)
Thus, the exponential function which shows the exponential growth rate of graduating women is: A(t) = A₀e∧(0.037t).

By using subtraction, we get that, the total yardage for the drive was that they gained 7 yards.
We are given that:
On a drive,
A football team first gains = 3 yards.
Then it lost = 11 yards.
Then it again gained = 15 yards.
We need to find its total yardage.
For this, we will subtract the yards lost from the yards gained by the team.
So, we get that:
total yardage = 3 + 15 - 11
total yardage = 18 - 11
total yardage = 7 yards.
