The area of a rectangle is (x3 – 5x2 3x – 15), and the width of the rectangle is (x2 3). if area = length × width, what is the length of the rectangle? x 5 x – 15 x 15 x – 5
The length of the rectangle is determined as x - 5 while the width is x² + 3.
Length of the rectangleThe length of the rectangle is determined by the following formula shown below;
Area = Length x width
L = A/w
x - 5

how do you calculate the average speed of a car that travels one mile at 30 mph and the second mile at 60 mph
Answer:
40mph
Step-by-step explanation:
use the speed = distance/time formula.
1. The first car has a speed of 30mph and travels one mile so the equation can be written as 30mph = 1/t.
Rearrange to get t = 1/30
1/30 of an hour is 2 minutes.
2. The second car has a speed of 60 mph and travels one mile so the equation can be written as 60mph = 1/t
Rearrange to get t = 1/60
1/60 of an hour is 1 minute.
The time it took for the total journey is 1 + 2 = 3 minutes
Writing 3 minutes as a fraction of an hour:
3/60 = 1/20
So using the s = d/t formula to calculate the average speed the formula can be written as (the speed is unknown, time is 1/20 and the distance is 2 miles):
Speed = 2/(1/20) = 2x20/1 = 40
Therefore the average speed of that car is 40 mph.

Austin is participating in a 30k race. He runs at an average speed of 10 kilometers per hour and walks at an average speed of 6 kilometers per hour. He wants to complete the race in 4 hours. Let x represent the number of hours he runs. Let y represent the number of hours he walks.
What equation in standard form relates x and y to the goal of covering 30 kilometers? (no spaces)
Using the relation between velocity, distance and time, the equation that relates x and y is given by:
x + y - 3 = 0.
What is relation between velocity, distance and time?Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
In this problem, he wants to run 30 km at a rate of 10 km per hour, hence:
[tex]10 = \frac{30}{t}[/tex]
10t = 30
t = 3.
The total time is 3 hours. Considering x as the number of hours he runs and y the number of hours he walks, along with the total time, the equation is given by:
x + y = 3.
In standard form:
x + y - 3 = 0.

how to do this?? help me please
Answer:
sinA = 0.79 tanA = 1.3
Step-by-step explanation:
Step1:
Find the length of the line going through the middle from A to C by using pythagorean theorem.
a = 13
b = 12
c= ?
c = sqrt(a^2 + b^2)
c = sqrt(13^2 +12^2)
c = 17.69
Step 2:
Use pythagorean theorem again to find the length of the line going from A to D.
a = ?
b = 14
c = 17.69
c^2 = a^2 + b^2
Now solve for a.
a^2 = c^2 - b^2
a = sqrt(c^2 - b^2)
a = sqrt(17.69^2 - 14^2)
a = 10.81
Step 3:
Use trignometry to find the values of sinA and tanA
sinA = opposite/hypotenuse = 14/17.69 = 0.79
tanA = opposite/adjacent = 14/10.81 =1.3
Point p divides segment ab in the ratio AP:PB = 8:12. Which letter marks the location of point p?
A. Point k
B. Point L
C. Point M
D. Point N
The point P is located on the second partition, when segment AB is divided into 5 subsegments
How to determine the location of point P?The ratio is given as:
AP : PB = 8 : 12
Simplify the ratio i.e. divide by 4
AP : PB = 2 : 3
The above ratio means that when the segment AB is divided into 5 equal segments, the point P is located on the second partition

A rectangular field has an area of 1,764 m2. the width of the field is 13 m more than the length. what is the perimeter of the field? 121 m 144 m 168 m 170 m
The Perimeter of the Field with a rectangular area of 1764 m² and the given width is; D: 170 m
What is the perimeter of the rectangle?We are given;
Area of rectangle; A = 1764 m²
We are told that the width of the field is 13 m more than the length. Thus;
W = L + 13
Thus;
L(L + 13) = 1764
L² + 13L = 1764
Using quadratic equation calculator;
L = 36 m
Thus;
W = 36 + 13
W = 49
Perimeter = 2(L + W)
Perimeter = 2(49 + 36)
Perimeter = 170 m

There are eleven people on a softball team and nine different positions. work through the questions to determine how many ways a coach can choose the players for the positions if amy does not want to pitch. if there are eleven people on the team and nine positions, how many total arrangements of the players can be made? if amy does not want to play pitcher, then there are now people available to pitch. assuming the pitcher has already been chosen, there are ten remaining players and remaining positions. how many ways are there to arrange the remaining players and positions?
Permutation helps us to know the number of ways an object can be arranged in a particular manner. The number of ways the remaining player can be arranged is 1,814,400.
What is Permutation?Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.
[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
Given that the team has 11 players while there are only 9 positions available, therefore, the number of ways the coach can choose 9 people and arrange them is,
[tex]^{11}P_9 = \dfrac{11!}{(11-9)!} = \dfrac{11!}{2!} = 19,958,400[/tex]
Now, since Amy does not want to be a pitcher, therefore, the number of ways the remaining people can be arranged in the place of the pitcher is 10. Also, the position remaining in the team is 8, while the number of people remaining is 10. Thus, the number of ways the remaining people can be arranged are,
[tex]\text{Number of ways}= ^{10}P_8 =\dfrac{10!}{(10-8)!} = 1,814,400[/tex]
Hence, the number of ways the remaining player can be arranged is 1,814,400.

The perimeter of an equilateral triangle must be at most 57 feet. Create an inequality to find what the length of the sides should be. Solve the inequality by showing all of your work and explaining each step.
Answer:
[tex]L[/tex] ≤ [tex]29[/tex]
Step-by-step explanation:
Given
Perimeter = 57 (at most)
Required
Determine the length of each side
The term at most in the values of the perimeter shows that the expression is an inequality and it means that perimeter can't exceed that value;
Let L represents the length of each sides;
Perimeter [tex]=L+L+L[/tex]
So,
[tex]L+L+L[/tex] ≤ [tex]57[/tex]
