The equation that will be used to find t is:
[tex]3(2-t)+1.5t=5[/tex]
Step-by-step explanation:Total distance that is traveled by Amir is: 5 miles.
and the total time taken by him is: 2 hours.
On the first part of the hike, Amir averaged 3 miles per hour.
Let t denote the time he spent hiking during the second i.e. difficult part of the hike.
Hence, the time he spent in first part of hike is: 2-t( Since, the total time was 2 hours)
Also, we know that:
[tex]Distance=Speed\times Time[/tex]
Hence, distance traveled in first part of hike is:
[tex]Distance=3\times (2-t)[/tex]
Now, the distance he will travel in second part of hike will be: 5-3(2-t)Since the total distance traveled by him is 5 miles.
It is given that his speed decreased to 1.5 miles per hour.
Now, we know that:
[tex]Time=\dfrac{Distance}{Speed}[/tex]
Hence, time spent by him in second part of hike is:
[tex]t=\dfrac{5-3(2-t)}{1.5}\\\\i.e.\\\\1.5t=5-3(2-t)\\\\i.e.\\\\3(2-t)+1.5t=5[/tex]

What is the point slope form of a line with slope 2 that contains the point (1,3)
Answer:
Option A y-3=2(x-1)
Step-by-step explanation:
we know that
The equation of a line into point slope form is equal to
y-y1=m(x-x1)
In this problem we have
(x1,y1)=(1,3)
m=2
substitute
y-3=2(x-1)
If (-4,32) and (7,-45) are two anchor points on the trend line, then find the equation of the line.
the equation of the trend line is y = -7x + 4.
To find the equation of the trend line using two points, we need to determine the slope (m) and the y-intercept (b) of the line. The slope is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the given points.
For the points (-4, 32) and (7, -45), the slope would be:
m = (-45 - 32) / (7 - (-4))
m = (-77) / (11)
m = -7
Now, we use the slope and one point to find the y-intercept using the point-slope form of the equation of a line, y - y1 = m(x - x1), and then we convert it to the slope-intercept form, y = mx + b.
Using point (-4, 32), the equation becomes:
32 = -7(-4) + b
32 = 28 + b
b = 32 - 28
b = 4
So, the equation of the trend line is y = -7x + 4.

Select the solution(s) of the original equation.
x = 1 + sqrt 2
x = 2 + sqrt 2
x = 3 + sqrt 2
x = 1 - sqrt 2
x = 2 - sqrt 2
x = 3 - sqrt 2
For this case we have to:
Let[tex]u = x + 1[/tex]
So:
[tex]u ^ 2-4u + 2 = 0[/tex]
We have the solution will be given by:
[tex]u = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]
Where:
[tex]a = 1\\b = -4\\c = 2[/tex]
Substituting:
[tex]u = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (2)}} {2 (1)}\\u = \frac {4 \pm \sqrt {16-8}} {2}\\u = \frac {4 \pm \sqrt {8}} {2}\\u = \frac {4 \pm \sqrt {2 ^ 2 * 2}} {2}\\u = \frac {4 \pm2 \sqrt {2}} {2}[/tex]
The solutions are:
[tex]u_ {1} = \frac {4 + 2 \sqrt {2}} {2} = 2 + \sqrt {2}\\u_ {2} = \frac {4-2 \sqrt {2}} {2} = 2- \sqrt {2}[/tex]
Returning the change:
[tex]2+ \sqrt {2} = x_ {1} +1\\x_ {1} = 1 + \sqrt {2}\\2- \sqrt {2} = x_ {2} +1\\x_ {2} = 1- \sqrt {2}[/tex]
Answer:
[tex]x_ {1} = 1 + \sqrt {2}\\x_ {2} = 1- \sqrt {2}[/tex]

Step-by-step explanation:
[tex]1 \div 2 \times base \times height = area[/tex]
[tex]1 \div 2 \times x \times 42.2 = \ 369.25 \[/tex]
[tex]x = 369.25 \div 21.1[/tex]
[tex] = 17.5[/tex]
Answer:
Base = 17.5 inches.
Step-by-step explanation:
Given : A triangle has an area of 369.25 square inches. The height of the triangle is 42.2 inches.
To find : What is the length of the base of the triangle.
Solution : We have given
Area of triangle = 369.25 square inches.
Height = 42.2 inches.
Area of triangle = [tex]\frac{1}{2}*base*height[/tex].
Plugging the values.
369.25 = [tex]\frac{1}{2}*base*42.2[/tex].
On multiplying both sides by 2
369.25 * 2 = base * 42.2
738.5 = base * 42.2
On dividing both sides by 42.2
Base = 17.5 inches.
Therefore, Base = 17.5 inches.

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) =x2 to the number of X-
intercepts in the graph of g(x) = x2 +2. Be sure to include the transformations that occurred between the parent functio
f(x) and its image g(x).
Answer:
The function f(x) intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.
Step-by-step explanation:
In this question you first form the table for values of x with corresponding values of f(x) that you will use to graph the function f(x)=x².Then do the same for the function g(x)=x²+2.Take a point from the parent function f(x) and compare it with its image in the function g(x) to identify the transformation that occurred.Graph the two equations to visually see the x-intercepts in both equations.
In the parent function f(x)=x² form a table as shown below;
x f(x)=x² coordinate to plot
-3 -3²=9 (-3,9)
-2 -2²=4 (-2,4)
-1 -1²=1 (-1,1)
0 0²=0 (0,0)
1 1²=1 (1,1)
2 2²=4 (2,4)
3 3²=9 (3,9)
Use the coordinates to plot the graph of f(x)=x² on a graph tool and see the number of x-intercept values
In the function g(x)=x²+2 also form your table for values of g(x) with corresponding values of x
x g(x)=x²+2 coordinate to plot
-3 -3²+2=9+2=11 (-3,11)
-2 -2²+2=4+2=6 (-2,6)
-1 -1²+2=1+2=3 (-1,3)
0 0²+2=2 (0,2)
1 1²+2=1+2=3 (1,3)
2 2²+2=4+2=6 (2,6)
3 3²+2=9+2=11 (3,11)
Use the coordinates to plot the graph of g(x)=x²+2 on a graph tool to determine the number of x intercept values
You can determine the transformation that occurred too, how?
Take a point on the parent function f(x) and compare it with its image in the function g(x)
Let take point (-3,9) and compare it to (-3,11).You notice x coordinate did not change but the y coordinate shifted 2 units upwards along the y-axis.To determine this dilation you subtract the coordinates of object point from that of image point.
[tex]=(\frac{0-0}{11-9}) =(\frac{0}{2} )=(0,2)[/tex]
The dilation was (0,2)
Solution
From the graphs, the function f(x), intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.
Which classification best represents a triangle with side lengths 10 in., 12 in., and 15 in.?
Answer:
It's an acute angled triangle.
Step-by-step explanation:
15^2 = 225
12^2 = 144
10^2 = 100
Adding:
10^2 + 12^2 = 244.
So as 15^2 < 12^2 + 10^2 this is an acute angled triangle.
The triangle with given sides of 10 inch , 12 inch and 15 inch is an acute angled triangle.
The length of three sides of a triangle are given
Length of first side = 10 inch
Length of second side = 12 inch
Length of third side = 15 inch
here we can observe that the third side is the longest side for the given triangle
Let us check whether the given triangle satisfies the Pythagorean theorem
For a right angled Pythagorean theorem is given by equation (1)
[tex]\rm H^2 = P^2 + B^2 .........(1)\\where \\H = Hypotenuse\\P = Perpendicular\\B = Base\\[/tex]
From the given data we can conclude that
[tex]\rm 15 ^2 = 225 \\10^2 = 100\\12^2 = 144 \\15^2 \neq 10^2 +12^2 \\\\Since\; 225\neq 244[/tex]
The given triangle does not satisfies the Pythagorean theorem and hence it is not a right angled triangle
also [tex]225< 244[/tex]
So we can conclude that it is an acute angled triangle.

If the unit selling price is $2.50 and the unit cost is
$1.00, what action is needed to maintain the gross
margin percentage when unit cost increases $0.25?
Lower the selling price.
Increase the selling price more than $0.25.
Maintain the same selling price.
Increase the selling price $0.25.
Answer:
D.
Increase by more than 0.25 dollars.
Step-by-step explanation:
What is the gross margin %?
Margin % = (2.50/1.00) * 100 = 250%
If the cost goes up 0.25 what will the selling price have to do to maintain a markup of 250%?
250% =(x/1.25) * 100%
Divide by 100%
250 / 100 = x / 1.25
2.5 = x / 1.25
Multiply both sides by 1.25
2.5 * 1.25 = x
3.125 = x
But that is really not the question. The question is, how much higher is that now than it used to be?
3.125 - 2.50 = 0.625 cents.
So you would have to increase the selling price by more than 0.25

x + 4y − z = −14
5x + 6y + 3z = 4
−2x + 7y + 2z = −17
A = -120
AX = -240
X = 2
Step-by-step explanation:
∵ x + 4y - z = -14
∵ 5x + 6y + 3z = 4
∵ -2x + 7y + 2z = -17
\left[\begin{array}{ccc}1&4&-1\\5&6&3\\-2&7&2\end{array}\right]=\left[\begin{array}{ccc}-14\\4\\-17\end{array}\right]
∴ A = 1(6×2 - 3×7) + (-4)(2×5 - 3×-2) + (-1)(5×7 - 6×-2)
∴ A = 1(12 - 21) + (-4)(10 - -6) + (-1)(35 - -12)
∴ A = -9 + (-4)(16) + (-1)(47) = -9 - 64 - 47 = -120
To find X replace the column of X by the column of the answer
\left[\begin{array}{ccc}-14&4&-1\\4&6&3\\-17&7&2\end{array}\right]
∴ AX = -14(6×2 - 3×7) + (-4)(4×2 - 3×-17) + (-1)(4×7 - 6×-17)
∴ AX = -14(12 - 21) + (-4)(8 - -51) + (-1)(28 - -102)
∴ AX = 126 + (-4)(59) + (-1)(130) = 126 - 236 - 130 = -240

A solid right pyramid has a square base. The length of the base edge is4 cm and the height of the pyramid is 3 cm period what is the volume of the pyramid?
Answer:
The volume of this pyramid is 16 cm³.
Step-by-step explanation:
The volume [tex]V[/tex] of a solid pyramid can be given as:
[tex]\displaystyle V = \frac{1}{3} \cdot b \cdot h[/tex],
where
[tex]b[/tex] is the area of the base of the pyramid, and[tex]h[/tex] is the height of the pyramid.Here's how to solve this problem with calculus without using the previous formula.
Imaging cutting the square-base pyramid in half, horizontally. Each horizontal cross-section will be a square. The lengths of these squares' sides range from 0 cm to 3 cm. This length will be also be proportional to the vertical distance from the vertice of the pyramid.
Refer to the sketch attached. Let the vertical distance from the vertice be [tex]x[/tex] cm.
At the vertice of this pyramid, [tex]x = 0[/tex] and the length of a side of the square is also [tex]0[/tex].At the base of this pyramid, [tex]x = 3[/tex] and the length of a side of the square is [tex]4[/tex] cm.As a result, the length of a side of the square will be
[tex]\displaystyle \frac{x}{3}\times 4 = \frac{4}{3}x[/tex].
The area of the square will be
[tex]\displaystyle \left(\frac{4}{3}x\right)^{2} = \frac{16}{9}x^{2}[/tex].
Integrate the area of the horizontal cross-section with respect to [tex]x[/tex]
from the top of the pyramid, where [tex]x = 0[/tex],to the base, where [tex]x = 3[/tex].[tex]\displaystyle \begin{aligned}\int_{0}^{3}{\frac{16}{9}x^{2}\cdot dx} &= \frac{16}{9}\int_{0}^{3}{x^{2}\cdot dx}\\ &= \frac{16}{9}\cdot \left(\frac{1}{3}\int_{0}^{3}{3x^{2}\cdot dx}\right) & \text{Set up the integrand for power rule}\\ &= \left.\frac{16}{9}\times \frac{1}{3}\cdot x^{3}\right|^{3}_{0}\\ &= \frac{16}{27}\times 3^{3} \\ &= 16\end{aligned}[/tex].
In other words, the volume of this pyramid is 16 cubic centimeters.

14 + 8m = 14 - 3m - 5m
Combine like terms
14 + 8m = 14 - 8m
Add 8m to each side
14 +8m +8m = 14 -8m +8m
14 +16m = 14
Subtract 14 from each side
14-14 +16m = 14-14
16m = 0
Divide by 16
16m/16 = 0/16
m = 0
Answer:
{0}
Step-by-step explanation:
The given equation is
[tex]14+8m=14-3m-5m[/tex]
We need to find the solution set of given equation.
Combine like terms on the right side of the given equation.
[tex]14+8m=14+(-3m-5m)[/tex]
[tex]14+8m=14+(-8m)[/tex]
[tex]14+8m=14-8m[/tex]
Add 8m on both sides.
[tex]14+8m+8m=14-8m+8m[/tex]
[tex]14+16m=14[/tex]
Subtract 14 from both sides.
[tex]14+16m-14=14-14[/tex]
[tex]16m=0[/tex]
Divide both sides by 16.
[tex]m=\frac{0}{16}[/tex]
[tex]m=0[/tex]
Therefore, the solution set is {0}.

1. Area of ΔJKL = [tex]\frac{1}{2}\times(\text{Distance of L from base JK})\times (JK)[/tex]
= [tex]\frac{1}{2}\times (3)\times (5)[/tex]
=7.5 square units
2. Area of ΔIJL = [tex]\frac{1}{2}\times(\text{Distance of J from base IL})\times (IL)[/tex]
= [tex]\frac{1}{2}\times (3)\times (5)[/tex]
= 7.5 square units
3. Area of triangle IKL = [tex]\frac{1}{2}\times(\text{Distance of H from base IL})\times (IL)[/tex]
= [tex]\frac{1}{2}\times (5)\times (5)[/tex]
= [tex]\frac{25}{2}=12.5[/tex] square units
Now area of ΔJKL + ΔIJL + ΔIKL = 7.5 + 7.5 + 12.5
= 27.5 square units
Option D. is the answer.

How many nickels and dimes are in $2.40 if there are two times more nickels than dimes?
A) 12 nickels and 6 dimes
B) 6 nickels and 12 dimes
C) 24 nickels and 12 dimes
D) 12 nickels and 24 dimes
The problem is solved by calculating that there are 24 nickels and 12 dimes to make a total of $2.40, given that there are twice as many nickels as dimes.
Explanation:The subject of this question is Mathematics, specifically dealing with simple money-based equations. In the problem you're presented with, you've been asked to figure out the number of nickels and dimes that make up $2.40, given that there are twice as many nickels as there are dimes.
First, we can start by understanding the value of each coin. A nickel is worth $0.05, and a dime is worth $0.10. With the condition expressed in the problem, let's express the number of dimes as x, thus the number of nickels would then be 2x.
Because of their respective values, the total value of the dimes would be 0.10x and the total value of the nickels would be 0.05 × 2x or 0.10x. Adding both together, we'd have 0.10x + 0.10x = 0.20x, which we know equals $2.40 from the problem. Solving the equation 0.20x = 2.40 gives us x = 12. That's your number of dimes. The nickels would be 2 × 12 = 24. So, the answer to your problem would be 24 nickels and 12 dimes.

The Addition Property of Equality allows us to add the same amount to both sides of an equation, so if x = 5, by adding 3 to both sides, x + 3 would be 8.
Explanation:The Addition Property of Equality is a principle of mathematics that states: if you add the same amount to both sides of an equation, the equation remains balanced. So, if we take the equation x = 5, according to the Addition Property of Equality, we can add 3 to both sides of the equation. This will give us: x + 3 = 5 + 3. Therefore, x + 3 = 8.
