Lauren's science class is taking a field trip to the nearest natural history museum. The museum is 62.5 miles from Lauren's school. The class plans to stop after 30 minutes, or 0.5 hours, to visit a local wildlife refuge. The bus driver plans to drive at an average speed of 50 miles per hour. How many hours will the second part of the trip take?
Write your answer as a whole number or a decimal.
Answers
The second part of the trip lasted 0.54 hours
Average speed is the ratio of total distance travelled to total time taken. It is given by:
Average speed = total distance / total time
Since the total distance is 62.5 miles and the average speed is 50 miles per hour, hence:
Average speed = total distance / total time
60 = 62.5 / total time
Total time = 25/24 hours
The first part of the journey takes 0.5 hours, hence:
Time for second part = 25/24 - 0.5 = 0.54 hours
Therefore the second part of the trip lasted 0.54 hours

Simplification
[tex] - 3d + 2 = 11[/tex]
Subtract both sides 2

East High School had a total of 12,510 people in
attendance during their 15-game soccer season. West
High School had a total of 14,310 people for 18 games.
On average, which school had a greater number of
people watching per game? How much greater?
Answers
On average East high school had a greater number of people watching per game that is, 834 > 795.
What do we mean by average?An average, which is frequently the sum of the numbers divided by the total number of the numbers in the group, is a single number that is selected to describe a group of numbers in simple English.For example, the average of the numbers 2, 3, 4, 7, and 9 is 5.The ratio obtained by dividing the total number of figures in a set by the total number of figures is known as the average.An average test score of 85 could represent the simple average or a result that lies halfway between two extremes.So, schools with a greater number of people matching the match per game:
Each high school:
12510/15834West high school:
14310/18795So, 834 > 795 which means Each high school > West high school.
Therefore, on average East high school had a greater number of people watching per game that is, 834 > 795.

Question 19 (03.06 LC)
Choose the equation below that represents the line passing through the point (1, -4) with a slope of 1/2. (1 point)
y - 4 = 1/2(x +1)
y + 4 = 2(x - 1)
y + 4 = 1/2(x - 1)
y - 4 = 2(x + 1)
Answers
Answer: y + 4 = 1/2(x - 1)
Step-by-step explanation:
The form of a straight line quation is y=mx+b, where m is the slope [(1/2) in this case] and b is the y-intercept (the value of y when x=0). We can already eliminate two of the options (2nd and 4th) since those slopes are 2.
To decide between y - 4 = 1/2(x +1) and y + 4 = 1/2(x - 1), we can see which equation is true for the point (1,-4):
Does y - 4 = 1/2(x +1) work for (1,-4)? [i.e., will y = -4 when x=1?]
y-4 = 1/2(1+1)?
y = 5 NO
-----------------------------
Does y + 4 = 1/2(x - 1) work for (1,-4)? [i.e., will y = -4 when x=1?]
y+4 = 1/2(1-1)
y = -4 YES
The equation is y + 4 = 1/2(x - 1)

9/4 divided by 3/8 with quotient
Answers
Answer:hey hunny boo it’s 61!✨ hope I helped :)
Step-by-step explanation:
The quotient of the given fractions is 6.
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Given that, 9/4 divided by 3/8.
When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction reversing its numerator and denominator is the first step in dividing fractions. Multiply the two numerators after that. Multiply the two denominators after that.
Here, 9/4 ÷ 3/8
= 9/4 × 8/3
= 3 × 2
= 6
Therefore, the quotient is 6.

What is the slope of the line tangent to the graph of y= (x^2 -2)/(x^2 + 1) when x =1
Answers
Step-by-step explanation:
first find the derivative and then substitute x=1
d/dx((x^2 -2)/(x^2 + 1)) = (2*x)/(1+x^2)+(4*x)/(1+(2*x^2)+x^4)+(-2*x^3)/(1+(2*x^2)+x^4)
substitute x=1

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
y = (x² - 2)/(x² + 1)
y' = [(x² + 1)(2x) - (x² - 2)(2x)] / (x² + 1)²
Put x = 1
dy/dx = [(1² + 1)(2) - (1² - 2)(2)] / (1² + 1)²
dy/dx = (4 + 2)/4
dy/dx = 6/4 = 3/2 = 1.5
Thus,
The slope is 1.5.

8. If n(AUB) = 8, n(A) = 6, n(B) = 4 then n(A∩B) _____.
Answers
Explanation:-
★(i).
A = { 1,2}
⇛ n (A ) = 2
B = { 3,4,5,6}
⇛ n (B) = 4
n(A)+n(B) = 2+4 = 6
★(ii).
The symbol ⇛ means Implies
★(iii).
A = Phi = {}
B = phi = {}
AUB = { } U { } = { }
AUB = phi = { }
(iv).
AUB = BUA is called Commutative law in sets uner union .
★(v).
Null set = Void set = Empty set = { }
Number of elements in the empty set = 0
⇛ Cardinal number of null set is zero (0)
★(vi). If AUB = B then B is the super set and A is the sub set of B
★(vii). A = { 1,2,3,4}
B = {2,4,6,8}
A-B = {1,2,3,4} - { 2,4,6,8}
=> A-B = { 1,3}
★(viii). n(AUB) = 8
n(A) = 6
n(B) = 4
We know that
n(AnB) = n(A)+n(B)-n(AUB)
⇛ n(AnB) = 6+4-8
⇛n(AnB) = 10-8
⇛ n(AnB) = 2
or n(AUB)+n(AnB) = n(A)+n(B)
⇛ 8+ n(AnB) = 6+4
⇛ 8+ n(AnB) =10
⇛ n(AnB) = 10-8
⇛ n(AnB) = 2
Therefore, n(AnB) = 2
