the answer would be 240 because wind speed is close to its median
find the midpoint of the line segment between the points (11, -5) and (-3, -7)
Answer:
(4, -6)
Step-by-step explanation:
(x1+x2)/2 + (y1+y2)/2 = midpoint
(11+-3)/2 = 8/2 = 4. x = 4
(-5 + -7)/2 = -12/2. y = -6

Identify the first five terms of the sequence in which an = 3n − 1 + 1.
The first five terms of the sequence represented as an = 3(n -1) + 1 are 1,4, 7, 10 and 13
How to determine the first five terms?The formula of the sequence is given as:
an = 3(n -1) + 1
The above sequence is an arithmetic sequence, and the first five terms are the values of the sequence when the value of n is from 1 to 5
i.e. n = 1, 2, 3, 4 and 5
Next, we set n = 1, 2, 3, 4 and 5, and substitute these values for n in an = 3(n -1) + 1
So, we have the following equations
First term
a1 = 3(1 -1) + 1 = 1
Second term
a2 = 3(2 -1) + 1 = 4
Third term
a3 = 3(3 -1) + 1 = 7
Fourth term
a4 = 3(4 -1) + 1 = 10
Fifth term
a5 = 3(5 -1) + 1 = 13
Hence, the first five terms of the sequence represented as an = 3(n -1) + 1 are 1,4, 7, 10 and 13

Eleanor is working her way through school. She works two part-time jobs for a total of 24 hours a week. Job A pays $5.80 per hour, and Job B pays
$7.40 per hour. How many hours did she work at each job the week that she made $158.40.
Step-by-step explanation:
a = hours at job A
b = hours at job B
a + b = 24
a = 24 - b
5.8a + 7.4b = 158.4
note we can use the a = 24 - b identity in the second equation :
5.8×(24 - b) + 7.4b = 158.4
139.2 - 5.8b + 7.4b = 158.4
1.6b = 19.2
b = 12 hours
a = 24 - b = 24 - 12 = 12 hours
she worked 12 hours on job A and 12 hours on job B.
The total area of town C and town D is 120,000 square miles. The area of town C is 30,000 square miles more than that of town D. Find the area land of each town.
Answer:
Find the area land of each town.
Let x be the area of town D
then, x+ 30000 is the area of town C
we know that,
the total area of town C and town D is 120,000 square miles.
x+x+30000=120000
2x= 90000
x=45000
Area of town D= 45000 square miles
Area of town C= 45000+30000= 75000 square miles.

The cost of a ticket to the circus is $22.00 for children and $46.00 for adults. On a certain day, attendance at the circus was 1,400 and the total gate revenue was $52,400. How many children and how many adults bought tickets?
The number of children and adults who bought the tickets at the circus was 500 and 900 respectively.
How to write and solve equation?let
x = number of childreny = number of adultsx + y = 1400
22x + 46y = 52,400
From equation (1)
x = 1400 - y
Substitute into (2)
22(1400 - y) + 46y = 52,400
30,800 - 22y + 46y = 52,400
- 22y + 46y = 52,400 - 30,800
24y = 21,600
y = 21,600 / 24
y = 900
substitute y into
x + y = 1400
x + 900 = 1400

Let's say you are paddling at 5mph and the current is 3 mph. Going upstream, you are going 2 mph and downstream, 8 mph.
8(b - c) = 464
7(b + c) = 644

Solve. Be sure to eliminate any extraneous solutions. X= square -2x+48
Answer: X = 6
Step-by-step explanation:
Substitute the x’s in the equation for the answer options that are provided.
Solutions of quadratic equation x = √(-2x + 48) are x = -8 and x = 6.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given, quadratic equation;
x = √(-2x + 48)
Squaring on both sides,
x² = -2x + 48
x² + 2x - 48 = 0
Now, we have to solve for x.
Simplifying,
x² + 8x - 6x - 48 = 0
(x + 8)(x -6) = 0
(x + 8) = 0 and (x -6) = 0
x = -8 and x = 6
After eliminating the extraneous solutions;

Answer:
(x - 3) is a factor of P(x)
Step-by-step explanation:
if (x - 3) is a factor of P(x) then P(3) = 0
P(3) = 2(3)³ + 5(3)² - 28(3) - 15

Line segment AB with endpoints A (5, 8) and B (7, 8) is translated 2 units down and 2

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of objects. The coordinates of the translated line segment will be A' (3,6) and B' (5,6).
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Since AB is a line segment the changes will occur on both the coordinates, therefore, if the line segment is translated 2 units down and 2 units left, the coordinates will be,
A = (5,8) → 2 units down ⇒ (5, 8-2) → 2 units left ⇒ (5-2, 8-2) = (3, 6)
B = (7,8) → 2 units down ⇒ (7, 8-2) → 2 units left ⇒ (7-2, 8-2) = (5, 6)
Hence, the coordinates of the translated line segment will be A' (3,6) and B' (5,6).

how to find the value of x and z
Answer:
z = 86 °
and, x = 2
Step-by-step explanation:
We know that a straight line is a 180 degree-angle. So, we know that
94 + z must equal 180, because they are the only two angles that make up the straight line.
from this information, (that 94 + z = 180) we can easily find z.
(this is typically an intuitive method of subtracting 94 from 180)
94 + z = 180
-94 -94
z = 86 °
-- we know that the relation between z and (10x + 74) must also be equal to 180, as they make up a straight line
if z = 86, then we can know that (10x + 74) must be equal to
(10x + 74) + 86 = 180
- 86 -86
(10x + 74) = 94
10x + 74 = 94
- 74 - 74
10 x = 20
÷ 10 ÷ 10
x = 2
so, z = 86 °
and, x = 2
