The length of the new base is 26.56 inches or [tex]26\frac{14}{25}[/tex] inches. Using the area of a right triangle, the required base is calculated.
How the area of a right triangle is calculated?The area of the right triangle is given by
A = [tex]\frac{1}{2}[/tex] × b × h sq. units
Where A -area; b -base; h -height;
Calculation:It is given that,
The right triangle has a base of length b = 8 1/2 = 8.5 inches and a height of length h = 12 1/2 = 12.5 inches.
So, its area is
A = [tex]\frac{1}{2}[/tex] × 8.5 × 12.5 = 53.125 sq. inches
When the height of the right triangle is reduced to 4 inches,
53.125 = [tex]\frac{1}{2}[/tex] × b × 4
⇒ b = 53.125/2
∴ b = 26.56 or [tex]26\frac{14}{25}[/tex] inches
Thus, the length of the new base is 26.56 or [tex]26\frac{14}{25}[/tex] inches.

2. How far will Seb travel if he bikes at this rate for 2.5 point, 5 hours?
The equation that represents the distance, in kilometers, Seb travels (d) based on how many hours he bikes (t) at this rate is d = 20t
1. Write an equation that represents the distance, in kilometers, Seb travels (d) based on how many hours he bikes (t) at this rate.The given parameter is
constant rate of 20 kilometers per hour.
This means that
Rate = 20km per hour
When Seb bikes for t hours, the distance is
d = rate * t
This gives
d = 20t
Hence, the equation that represents the distance, in kilometers, Seb travels (d) based on how many hours he bikes (t) at this rate is d = 20t
How far will Seb travel if he bikes at this rate for 2.5 point, 5 hours?This means that
t = 5
So, we have:
d = 20 * 5

Find the length of the arc of a circle of diameter 14 meters subtended by a central angle of π/6 radians. Round your answer to two decimal places
The length of the arc of the circle is 3.67 meters
What is an arc?The arc of a circle is a part of the circumference that makes up the circle
How to determine the length of the arc?From the question, we have the following parameters
Diameter, d = 14 meters
Central angle = π/6 radians
Start by calculating the radius of the circle using
Radius, r = Diameter/2
This is so because radius is half the diameter
So, we have
r = 14 meters/2
Evaluate the quotient of 14 meters and 2
r = 7 meters
The length of the arc of the circle is then calculated using
L = Radius * Central angle
Substitute known values in the above equation
L = 7 meters * π/6
Evaluate the product of 7 and π/6
L = 3.67 meters
Hence, the length of the arc of the circle is 3.67 meters

Function: y=x2+5x−7
Vertex: ( , )
Solutions: ( , ) and ( , )
Answer:
vertex : (-5/2, -53/4)
solutions: (-(5-sqrt53)/2, 0) (-(5+sqrt53)/2, 0)
Step-by-step explanation:
1.The vertex of the function is (-5/2, -53/4).
2.We have two solutions:
x = (-5 + √53) / 2 ≈ 0.73
x = (-5 - √53) / 2 ≈ -5.73
To find the vertex and solutions of the function y = x^2 + 5x - 7, we can use the formula for the vertex and the quadratic formula for finding solutions.
1. Vertex:
The vertex of a quadratic function in the form y = ax^2 + bx + c can be found using the formula:
x = -b / (2a)
y = f(x) = ax^2 + bx + c
Given: a = 1, b = 5, c = -7
x = -5 / (2 * 1) = -5 / 2
Now, substitute the value of x into the equation to find y:
y = (-5/2)^2 + 5 * (-5/2) - 7
y = 25/4 - 25/2 - 7
y = 25/4 - 50/4 - 7
y = (25 - 50 - 28) / 4
y = -53 / 4
So, the vertex of the function is (-5/2, -53/4).
2. Solutions (or roots or x-intercepts):
To find the solutions (x-intercepts) of the function, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / 2a
Given: a = 1, b = 5, c = -7
x = (-5 ± √(5^2 - 4 * 1 * -7)) / 2 * 1
x = (-5 ± √(25 + 28)) / 2
x = (-5 ± √53) / 2
Now, we have two solutions:
x = (-5 + √53) / 2 ≈ 0.73
x = (-5 - √53) / 2 ≈ -5.73
So, the solutions of the function are approximately x ≈ 0.73 and x ≈ -5.73.

the measure of the angels of a quadrilateral are in ratio 2:4:5:7 find the measure of each of it's angles
Answer:
Step-by-step explanation:
If they all exist in proportion to one another (READ: ratio) then multiplying each of the angles by the same number (here, some unknown "x" value) will maintain the proportionality. Since all the angles of a quadrilateral have to add up to equal 360, then
2x + 4x + 5x + 7x = 360 and
18x = 360. Divide both sides by 18 to get that
x = 20. That means that
2x = 2(20) = 40 and
4x = 4(20) = 80 and
5x = 5(20) = 100 and
7x = 7(20) = 140. Adding all of those up:
40 + 80 + 100 + 140 = 360
Answer:
40,80,100,140
Step-by-step explanation:
Let the ratio 2:4:5:7 angles be 2x, 4x, 5x, 7x
Now
2x + 4x + 5x + 7x=360 degrees
18x = 360 degrees
x =360/18
x=20
2x=2 *20=40
4x=4 *20=80
5x=5 *20=100
7x=7* 20=140

2. Us i ng the filled table above,
a) calculate just one PED.
b) Is the demand elastic or inelastic?
c) Based on your answer to c) what price change would you recommend to increase TR?
The price elasticity of demand of the pen will be -0.2.
How to compute the elasticity?The demand and supply schedule will be:
Price Qd. Qs
$10. 250. 100
$20. 200. 90
$30. 180. 80
The price elasticity of demand from $1 to $2 will be:
= Percentage change in quantity demanded/percentage change in price
Percentage change in quantity demanded will be:
= (200 - 250)/250 × 100
= -20%
Percentage change in price will be:
= (20 - 10)/10 × 100
= 100%
Therefore, the elasticity of demand will be:
= -20/100
= - 0.2
The value gotten illustrates an inelastic demand.
In order to increase the total revenue, the price can be reduced as it will lead to more sales.

e. The two most drastic rises in gasoline prices in April 2021 and April 2022 can be attributed to spikes in demand relative to supply.
What causes gasoline prices to rise?Gasoline prices rise when there is an increased demand relative to supply.
Increasing prices in gasoline prices can also be attributed to cuts in production and supply by the oil cartel.
What is the difference between Absolute and Relative Changes?An absolute change is a dollar change from one period to another.
A relative change is an absolute change expressed in percentages.

A box contains orange balls and green balls. The number of green balls is seven more than four times the number of orange balls. If there are 102 balls altogether, then how many green balls and how many orange balls are there in the box?
green balls = 83
orange balls = 19
Step-by-step explanation:
green balls = g
orange balls = r
g = 7 + 4r
g + r = 102
7 + 4r + r = 102
5r = 95
r = 19
g + 19 = 102
g = 83

What was the rat population in 2004 ?
rats
What does the model predict the rat population was in the year 2012 ?
rats
The rat population is 2004 and 2012 are 24. 8 millions and 31. 6 millions respectively.
How to determine the populationGiven the function of the population to be;
n (t) = 24 e^0. 015t
Where;
t is measured in years since 2004n(t) is measured in millionsIn 2004, t = 1
Substitute into the formula;
n(1) = 24 e^0. 015t
n(1) = 24 e^(0.015 × 1)
n(1) = 24 e^0. 015
n(1) = 24. 8 millions
In year 2012, t = 8
n(8) = 24 e^(0. 015 × 8)
n(8) = 24e^0. 12
n(8) = 31. 6 millions
Thus, the rat population is 2004 and 2012 are 24. 8 millions and 31. 6 millions respectively.
