Answer: 25 miles
Step-by-step explanation:
Since, the total distance = 31 miles.
Let he walks x miles at the rate of 4 miles per hour.
⇒ he walks remaining (31-x) miles at the rate of 50 miles per hour.
According to the question,
[tex]\frac{x}{4} + \frac{31-x}{50} = 2[/tex]
⇒ [tex]\frac{25x}{100} + \frac{62-2x}{100} = 2[/tex]
⇒ [tex]\frac{25x+62-2x}{100}= 2[/tex]
⇒ [tex]\frac{23x+62}{100}= 2[/tex]
⇒ [tex]23 x + 62 = 200[/tex]
⇒ [tex]23 x = 200 - 62[/tex] ( by subtracting 62 on both sides )
⇒ [tex]23 x = 138[/tex]
⇒ [tex]x=\frac{138}{23}[/tex] ( Dividing both sides by 23 )
⇒ [tex]x = 6[/tex]
Thus, the distance he pays to the cab driver = 31-x= 31 - 6 = 25 miles.
Therefore, He pays to the cab driver for 25 miles.
Distance that must be paid to the taxi = 25 miles
Further explanationLinear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
• At constant velocity motion:
the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vtAn equation of constant velocity motion
[tex]\large {\boxed {\bold {x = v \times \: t}}}[/tex]
x = distance = m
v = speed = m / s
t = time = seconds
so

A mountain path is 31 miles long
The distance traveled by tourists = x1
The distance traveled taxi = x2, such that
x1 + x2 = 31
x1 = 31-x2
total travel time (t) = 2 hours
tourist speed = v1 = 4 mph
taxi speed = v2 = 50 mph
time taken by tourists = t1
[tex]\rm \dfrac{x1}{v1}=\dfrac{x1}{4}[/tex]
the time taken by taxi = t2
[tex]\rm \dfrac{x2}{v2}=\dfrac{x2}{50}[/tex]
total time = t1 + t2
[tex]\rm 2=\dfrac{x1}{4}+\dfrac{x2}{50}\\\\2=\dfrac{25x1+2x2}{100}\\\\200=25(31-x2)+2x2\\\\200=775-25x2+2x2\\\\575=23x2\\\\x2=\boxed{\bold{25~miles}}[/tex]

In May, 2018 a store had a furniture with a listed price of $550, having a sales tax of 3% on the listed price. Next month the price increased by 33 1/3 %. What sales tax should be paid in dollars on the new price?
The sales tax that should be paid in dollars on the new price is $22
Further explanationOrder of Operations in Mathematics follow this following rule :
ParenthesesExponentsMultiplication and DivisionAddition and SubtractionThis rule is known as the PEMDAS method.
In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
Let us tackle the problem !
Given:
Initial Price = $550
Sales Tax = 3%
Percentage of Price Increase = 33¹/₃ %
Unknown:
Final Sales Tax = ?
Solution:
[tex]\texttt{Final Price} = \texttt{Initial Price} \times (100\% + \texttt{Percentage of Price Increase} )[/tex]
[tex]\texttt{Final Price} = \$550 \times (100\% + 33\frac{1}{3}\% )[/tex]
[tex]\texttt{Final Price} = \$550 \times (100\% + \frac{100}{3}\% )[/tex]
[tex]\texttt{Final Price} = \$550 \times (\frac{300}{3}\% + \frac{100}{3}\% )[/tex]
[tex]\texttt{Final Price} = \$550 \times (\frac{400}{3}\%)[/tex]
[tex]\texttt{Final Price} = \$550 \times (\frac{4}{3})[/tex]
[tex]\texttt{ }[/tex]
[tex]\texttt{Final Sales Tax} = 3\% \times \texttt{Final Price}[/tex]
[tex]\texttt{Final Sales Tax} = 3\% \times \$550 \times (\frac{4}{3})[/tex]
[tex]\texttt{Final Sales Tax} = \frac{3}{100} \times (\frac{4}{3}) \times \$550[/tex]
[tex]\texttt{Final Sales Tax} = \frac{4}{100} \times \$550[/tex]
[tex]\texttt{Final Sales Tax} = 4 \times \$5.5[/tex]

What is the solution set of x2 – 10 = 30x?
So for this, I will be completing the square to solve for x. Firstly, add 10 and subtract 30x on both sides of the equation:
[tex]x^2-30x=10[/tex]
Next, we want to make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and square the quotient. Once you get that result, add it to both sides of the equation:
[tex]30\div 2 = 15\\15^2=225\\\\x^2-30x+225=235[/tex]
Now, factor the left side:
[tex](x-15)^2=235[/tex]
Next, square root both sides:
[tex]x-15=\pm\ \sqrt{235}[/tex]
Now, add 15 to both sides of the equation:
[tex]x=15\pm \sqrt{235}[/tex]
This is the exact solution. To find the approximate solution, solve the left side twice -- once with the plus sign, once with the minus sign:

4x + 3y = 11
x - y = 8
Answer:
C. (5, -3)
Step-by-step explanation:
4x + 3y = 11
x - y = 8 (multiply by 3) --> 3x - 3y = 24
4x + 3y = 11
3x - 3y = 24
---------------------add
7x = 35
x = 5
5 - y = 8
y = 5 - 8
y = -3
(5, -3)
Answer:
C. (5, -3)
Step-by-step explanation:
Rewrite the first equation.
Multiply the second equation by 3 and write it under the first equation.
4x + 3y = 11
3x - 3y = 24
Now add the equations.
7x = 35
Divide both sides by 7.
x = 5
Substitute 5 for x in the original first equation:
4(5) + 3y = 11
20 + 3y = 11
3y = -9
y = -3
Solution: (5, -3)
Which table represents a nonlinear function?
Answer:
The table that represents the nonlinear function is the one where the x-values are -7, -5 and 0 and the y-values are -3, 0 and 3.
Step-by-step explanation:
In order for a table to represent a linear function, there needs to be a consistent change in y-values divided by the change in x-values. For example, for any two points on the table when we subtract two y-values and divide by the number we get when we subtract two x-values, this change should be represented throughout the table. So, in the case of the other three tables, when we choose two points from the table, such as (-5, 7) and (-2,6) and put them into an equation (y2-y1/x2-x1) or (6-7)/(-2-(-5)) we would get a change of -1/3. However, when we apply this concept to the table where x-values are -7,-5, and 0, we see that the change is not consistent between points, so the function must be nonlinear.

Phillip bought 12 used cds and dvds. CDs cost 2 each and dvds cost 3 each. He spent 32 not including tax. How many dvds did Phillip buy?
Answer:
Eight
Step-by-step explanation:
We have two conditions:
(1) C + D = 12
(2) 2C + 3D = 32 Subtract D from each side of Equation (1)
C = 12 - D Multiply both sides by 5
2(12 – D) + 3D = 32 Remove parentheses
24 – 2D + 3D = 32 Combine like terms
24 + D = 32 Subtract D from each side
D = 8

I have tried multiple times on this question and I don't understand it. Matikas is writing a coordinate proof to show that the midpoints of a quadrilateral are the vertices of a parallelogram. He starts by assigning coordinates to the vertices of quadrilateral RSTV and labeling the midpoints of the sides of the quadrilateral as A, B, C, and D.
Enter the answers, in simplified form, in the boxes to complete the proof.
Answer:
coordinate of point A is (a,b)
coordinate of point C is (2c,d)
slope of AD and BC =[tex]\frac{b}{a-c}[/tex]
Step-by-step explanation:
According to midpoint formula
If we have points P [tex](x_{1} ,y_{1} )[/tex] and Q [tex](x_{2} ,y_{2} )[/tex]
then the coordinate (x,y) of mid point of line PQ is given by
[tex]x=\frac{x_{1} +x_{2} }{2}[/tex] and [tex]y=\frac{y_{1} +y_{2} }{2}[/tex]
now from the given diagram A is the mid point of line joining R(0,0) and S(2a,2b)
Using midpoint formula, coordinates of point A is given by
[tex]x=\frac{0+2a}{2}= a[/tex] and [tex]y=\frac{0+2b}{2} =b[/tex]
so we have
coordinate of point A is (a,b)
Also C is the midpoint of line joining T (2c,2d) and V(2c,0)
coordinate of point C is given by
[tex]x= \frac{2c+2c}{2} =2c[/tex] and [tex]y=\frac{2d+0}{2} =d[/tex]
so we have
coordinate of point C is (2c,d)
it is given that coordinate of point B is (a+c, b+d) and coordinate of D is (c,0)
If we have points P [tex](x_{1} ,y_{1} )[/tex] and Q [tex](x_{2} ,y_{2} )[/tex]
then the slope of PQ =[tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]
hence slope of AD= [tex]\frac{0-b }{c-a} [/tex]
=[tex]\frac{-b}{c-a}[/tex]
=[tex]\frac{-b}{-(a-c)}[/tex]
=[tex]\frac{b}{a-c}[/tex]
and slope of BC =[tex]\frac{d-(b+d)}{2c-(a+c)}[/tex]
=[tex]\frac{d-b-d}{2c-a-c}[/tex]
=[tex]\frac{-b}{c-a}[/tex]
=[tex]\frac{b}{a-c}[/tex]
so we have
slope of AD and BC =[tex]\frac{b}{a-c}[/tex]
Answer:
Co-ordinates of A are ( a, b )
Co-ordinates of C are ( 2c, d )
Slope of line segments AD and BC is [tex]\frac{-b}{c-a}[/tex]
Step-by-step explanation:
We know that, the co-ordinates of the mid-point of a line segment having end points (x,y) and [tex](x_{1} , y_{1} )[/tex] is [tex](\frac{x+x_{1} }{2} , \frac{y+y_{1} }{2} )[/tex]
Now as 'A' is the mid-point of the line segment RS having end points (0,0) and (2a,2b).
The co-ordinates of A will be ( [tex]\frac{0+2a}{2}[/tex], [tex]\frac{0+2a}{2}[/tex] ) i.e [tex]( a, b )[/tex]
Now as 'C' is the mid-point of the line segment TV having end points (2c,2d) and (2c,0).
The co-ordinates of C will be ( [tex]\frac{2c+2c}{2}[/tex], [tex]\frac{2d+0}{2}[/tex] ) i.e. [tex]( \frac{4c}{2} , \frac{2d}{2})[/tex] i.e. [tex]( 2c, d )[/tex].
Further, we need to find the slope of line segments AD and BC.
AD has end points [tex]( a, b )[/tex] and [tex]( c, 0 )[/tex]. Then the slope of AD will be [tex]\frac{0-b}{c-a}[/tex] i.e [tex]\frac{-b}{c-a}[/tex]
Similarly, BC has end points [tex]( a+c, b+d )[/tex] and [tex]( 2c, d )[/tex]. Then the slope of BC will be [tex]\frac{d-b-d}{2c-a-c}[/tex] i.e [tex]\frac{-b}{c-a}[/tex]
Hence, the slope of AD and BC is [tex]\frac{-b}{c-a}[/tex].

Which statement about the graph y= 4x - 10 is NOT true?
A. The slope of the line can be written as 4/1
B. The graph crosses the y-axis 10 units below the origin
C. The line has a constant rate of change
D. The graph contains the point (4, -10)
Answer:
D. The graph contains the point (4, -10)
Step-by-step explanation:
We have been given an equation of a function: [tex]y=4x-10[/tex]. We are asked to find which of the given statements are not true about our given function.
A. The slope of the line can be written as 4/1.
We can see from our given equation that slope is 4 we can write 4 as 4/1 as it will not change value of 4, therefore, option A is true.
B. The graph crosses the y-axis 10 units below the origin.
Since we know that b represents y-intercept, where line crosses y-axis. y-intercept for our given equation is -10, which means that our given line crosses y-axis at -10 (10 units below the origin), therefore, option B is true.
C. The line has a constant rate of change.
We can see that slope of line is 4 which means with each increase in x, y will increase by 4 units, which remains constant, therefore, option C is true indeed.
D. The graph contains the point (4, -10)
Since we know that y-intercept is -10, which occurs at x equals 0, therefore, the graph does not contain the point (4,-10) and option D is not true.
plz help Pru, Piper, and Phoebe share spices in the ratio 5:3:4. If Pru has 24 more spices than Piper, how many spices does Phoebe have?
Answer:
Step-by-step explanation:
Pru, Piper, Phoebe ratio 5:3:4vadded = 12
What this means is Pru has 5/12 of the total amount, Piper has 3/12 of the total amount, and Phoebe has 4/12 of the total amount of spices.
pru = piper + 24
5/12x = 3/12x + 24
5/12x - 3/12x = 24
2/12x = 24
x = 24 / (1/6)
x = 24 * 6
x = 144 spices in total
Pru has : 5/12(144) = 720/12 = 60 spices
Piper has : 3/12(144) = 432/12 = 36 spices
Phoebe has : 4/12(144) = 576/12 = 48 spices
I hope this can help.
Answer:
48
Step-by-step explanation:
Pru, Piper, and Phoebe share spices in the ratio 5:3:4
5+3+4=12
So Pru has 5/12 share of spices, Piper has 3/12 share of spices, and Phoebe has 4/12 share of spices.
If Pru has 24 more spices than Piper, (5/12 - 3/12)=2/12 share of spices =24
Total spices = 24x12/2 = 144
Phoebe has 4/12x144 = 48 spices
One number is equal to two times a second number. Two times the first number plus two times the second number is 24. If you let x stand for the first number and y for the second, what are the two numbers? A. x = –24, y = –12 B. x = 12, y = 6 C. x = 8, y = 4 D. x = 24, y = 12
Answer:
C, x = 8 and y = 4
Step-by-step explanation:
Let's isolate y.
x = 2y
Divide both sides by 2.
x/2 = y
Now plug it in to the other equation.
2x + 2(x/2) = 24
Simplify.
2x + x = 24
Simplify.
3x = 24
Divide both sides by 3.
x = 8
Now plug x back into the original equation.
8/2 = y
Simplify.
4 = y
Therefore, the answer is C, x = 8, y = 4.
jacie can swim 3/4 of a mile in 3/8 of an hour.how far can she swim in one hour?
Answer:
2 miles
Step-by-step explanation:
convert 3/4 into 6/8. With this you have a ratio of 6/8 miles to 3/8 hours. Meaning 2/8 mile is equal to 1/8 of an hour. With this you can find that Jacie can swim 2 miles in a hour
Jacie can swim 2 miles in one hour, based on her speed of swimming 3/4 of a mile in 3/8 of an hour.
The student has asked how far Jacie can swim in one hour if she can swim 3/4 of a mile in 3/8 of an hour. To find out how far she can swim in one hour, we need to calculate her swimming speed and then use that speed to determine the distance she can cover in one full hour.
First, we determine Jacie's speed by dividing the distance by the time:
Speed = Distance / Time
Speed = (3/4) mile / (3/8) hour = 2 miles per hour
Now that we know Jacie swims at a speed of 2 miles per hour, we can find out the distance she swims in one hour simply by considering the speed:
Distance in one hour = Speed / Time
Distance in one hour = 2 miles per hour / 1 hour = 2 miles
Therefore, Jacie can swim 2 miles in one hour.

As a salesperson at trading cards unlimited Justin receives a monthly base pay Plus commission on all of that he sells. If he sells for $100 worth of merchandise in one month he is paid $500 if he sells $700 of merchandise in one month he is paid $575 find Justin’s salary when he sells $2500 worth of merchandise
Answer:
If he sells $2500 worth of merchandise, his salary is $800.
Step-by-step explanation:
You can find a function that gives you his salary as a function of the sales.
You have two points: (100, 500) and (700, 575).
y = mx + b
m = (575 - 500)/(700 - 100) = 75/600 = 0.125
Now use point (100, 500) to find b.
y = mx + b
500 = 0.125(100) + b
500 = 12.5 + b
b = 487.5
y = 0.125x + 487.5
If he sells $2500, then x = 2500.
y = 0.125x + 487.5
y = 0.125(2500) + 487.5
y = 800
If he sells $2500 worth of merchandise, his salary is $800.

the equation cos-1 3.4/10 =x can be used to determine the measure of angle BAC. What is the degree of measure angle BAC? Round to the nearest whole degree.
Answer:
70°
Step-by-step explanation:
x = [tex]cos^{-1}[/tex]([tex]\frac{3.4}{10}[/tex]) ≈ 70°
Answer:
<BAC= 70 degrees.
Step-by-step explanation:
The given equation to find angle BAC that is x is :
x=[tex]cos^{-1} \frac{3.4}{10}[/tex]
Or ,[tex]x=cos^{-1} 0.34[/tex]
Using calculator to find the arc of cosine0.34 we have :
x=70.1231
This when rounded to nearest whole degree is 70 degrees.
<BAC= 70 degrees.

Calvin goes shopping over the weekend and buys a new pair of shoes,a T-Shirt, a pair of sunglasses, and a hat that costs $9. The shoes are twice as much as the shirt, and the sunglasses are half as much as the shirt. The total cost of his purchase is $65. How much does each cost?
Answer:
I got you :)
Step-by-step explanation:
okay so if the hat is 9$ there is only 56$ left . it says the shoes are twice as much as the shirt , so i just went in and seen how much ill have left if i split it all. So i said 32$ for the shoes , because half of 32$ for shoes would mean 16$ for the shirt which would be 48. Then it says the sunglasses are half as much as the shirt and half of 16 is 8. When we add 32+16+8+9 we get 65$.
the first term of a sequence is 13 the term-to-term rule is take away 5 workout the 4th term
Answer:
[tex]a_{4}[/tex] = - 2
Step-by-step explanation:
given the term to term rule is subtract 5, then
[tex]a_{2}[/tex] = 13 - 5 = 8
[tex]a_{3}[/tex] = 8 - 5 = 3
[tex]a_{4}[/tex] = 3 - 5 = - 2
The fourth term is -2.
Given that,
the first term of a sequence is 13.The term-to-term rule is take away 5Based on the above information, the calculation is as follows:
Second term is
= 13 - 5
= 8
Third term is
= 8 -5
= 3
And, the fourth term is
= 3-5
= -2
Therefore we can conclude that The fourth term is -2.

Miguel has two same size rectangles divivded into the same number of equal parts. One rectangle has 3/4 of the parts shaded, and the other has 5/8 of the parts shaded. Into how many parts could each rectangle be divided?
Final answer:
Each rectangle can be divided into 8 equal parts, allowing [tex]\frac{3}{4}[/tex] and [tex]\frac{5}{8}[/tex] to be expressed with the same denominator for comparison.
Explanation:
To determine how many parts each rectangle can be divided, we need to find a common denominator that allows us to express [tex]\frac{3}{4}[/tex] and [tex]\frac{5}{8}[/tex] using the same size parts. The smallest number that both denominators 4 and 8 can divide into without a remainder is 8. Therefore, the first rectangle can be divided into 8 equal parts, with 6 of those parts being shaded (since [tex]\frac{3}{4}[/tex] is equivalent to [tex]\frac{6}{8}[/tex]). The second rectangle is already divided into 8 equal parts with 5 of those parts being shaded.
