find the coordinates of the midpoint of HK if H(-1,2) and K(-7,-4)
Answers
Answer:
The midpoint of HK is (-4, 1)
Step-by-step explanation:
We are given two coordinates H(-1, 2) and K(-7, -4)
We need to find the midpoint of HK.
We have formula to find the midpoint.
[tex](\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} }[/tex]
Here [tex]x_1 = -1, y_1 = 2, x_2 = -7 and y_2 = -4[/tex]
Now plug in these values in the above formula, we get
[tex](\frac{-1 + (-7)}{2} , \frac{2 +(-4)}{2} )[/tex]
[tex](\frac{-8}{2}, \frac{-2}{2} ) = (-4, -1)[/tex]
So, the midpoint of HK is (-4, 1)
Elio Makes candles that are 14 cm tall. Each candle burns eight hours before going out. He is wondering how many hours a 21 cm tall candle can burn for.
Answers
Final answer:
A 21 cm tall candle should burn for 12 hours, as it is 1.5 times taller than a 14 cm candle which burns for 8 hours.
Explanation:
The problem is one of direct proportion where the height of the candles is directly proportional to the burning time. If a 14 cm tall candle burns for 8 hours, then a 21 cm tall candle, which is 1.5 times taller, should burn for 1.5 times longer. Hence, to calculate the burning time for the 21 cm candle, we multiply 8 hours by 1.5.
Calculation:
21 cm / 14 cm = 1.5
8 hours × 1.5 = 12 hours
Therefore, a 21 cm tall candle should burn for 12 hours.
A flat-screen television has a length that is 1 more inch than its width. The area of the television's screen is 1500 in cubed. To the nearest whole inch, what are the dimensions of the television
Answers
Final answer:
The dimensions of the flat-screen television with an area of 1500 square inches are approximately 38 inches in width and 39 inches in length.
Explanation:
To find the dimensions of a flat-screen television with an area of 1500 square inches and a length that is 1 inch more than its width, we can set up a quadratic equation. Let the width be w inches, then the length would be w + 1 inches. The area of the television's screen is given by the formula:
Area = width × length
Substituting the given values, we get:
1500 = w × (w + 1)
This simplifies to:
w² + w - 1500 = 0
Solving this quadratic equation, we find two potential solutions for w, but only the positive value makes sense in this context. Once we find the value of w, the width, we can then add 1 to get the length.
After calculating, we find that the width w is approximately 38 inches, and the length is approximately 39 inches. Therefore, the dimensions of the television are 38 inches by 39 inches to the nearest whole inch.
which statements are true about the race
Answers
stuart finishes the race 1 second after peter
thats all I am getting as true statements
Stuart starts at 60 yards from the finish.
Peter starts at 100 yards from the finish.
Stuart runs 60 yards, and Peter runs 100 yards.
Also, now look at the x-axis.
Stuart take 13 seconds to complete the race, and Peter takes 12 seconds to complete the race.
a.
Stuart ran 60 yards in 13 sec.
Peter ran 100 yards in 12 sec.
Peter ran a longer distance in less time, so Peter runs at a faster rate.
b.
Stuart ran 60 yd. Peter ran 100 yd.
100 yd - 60 yd = 40 yd.
They both started at the same time, so Stuart had a 40 yd head start.
Stuart still lost the race.
c.
Peter does not have a head start. He must run 40 extra yards.
d.
Stuart runs 60 yd.
Peter runs 100 yd.
Peter runs the longer race.
e.
Stuart finishes in 13 sec.
Peter finishes in 12 sec.
Stuart does take 1 more second than Peter.
f.
Peter ran 100 yd in 12 sec.
Speed = distance/time = (100 yd)(12 sec) = 8.33 yd/sec
Every statement is explained above.
Now you need to decide which ones are true and which ones are false based on the explanations.

how do I write A quadratic Equation From a Parabola and A Chart
Answers
2. If the parabola is upside down remember to add in a negative in front of a.
3. Substitute the (x,y) coordinates of the vertex in the vertex form equation remember h=x and k=y.
4. Now, substitute any point (x,y) from the table into the x and f (x) of the vertex form, f (x)=y.
5. Solve for a.
6. Goto #3 and sub in the a value from step #5.
7. You are done and have a equation in vertex form.
To change to standard just distribute (a) value into the equation (distribution property) and simplify (add or subtract like terms).
To write a quadratic equation from a parabola and a chart, you can use the vertex form of a quadratic equation which is y = a(x - h)^2 + k. Substitute the coordinates of two points on the parabola into the equation and solve for the unknown variables. Once you have the values, substitute them back into the equation to obtain the final quadratic equation.
Explanation:To write a quadratic equation from a parabola and a chart, you will need to use the vertex form of a quadratic equation which is y = a(x - h)^2 + k. In this form, (h,k) represents the coordinates of the vertex of the parabola.
The equation can be determined from the chart by finding two points on the parabola and substituting their coordinates into the equation.
Here are the step-by-step instructions:
Select two data points from the chart that lie on the parabola.Substitute the x and y coordinates of the first point into the equation y = a(x - h)^2 + k.Substitute the x and y coordinates of the second point into the equation.Now you have two equations with two unknowns (a and h), solve the system of equations to find the values of a and h.Once you have obtained the values of a and h, you can substitute them back into the equation y = a(x - h)^2 + k to get the final quadratic equation.Which expression is equivalent to (^4√5^3)^(1/2)

Subtract the following polynomials, then place the answer in the proper location on the grid.
Answers
To subtract polynomials, align the terms and subtract their corresponding coefficients.
Explanation:Subtracting polynomials involves subtracting the corresponding terms from each other. Start by aligning the like terms and then subtract their coefficients. If there are any terms that cannot be simplified further, leave them as they are in the final answer. For example, if we have (3x^2 + 2x - 5) - (2x^2 - 3x + 4), we align the terms and subtract them to get (3x^2 - 2x^2) + (2x + 3x) + (-5 - 4) = x^2 + 5x - 9.

Your friend has 5 more then twice as many game tokens as your sister. Let T be the number of game tokens your sister has. Write and expression for the number of game tokens your friend has
Answers
Hope this helps and please rate as brainliest!!! thx!!! ;)
The number of game tokens that the friend has can be represented as the algebraic expression '2T + 5', where 'T' represents the number of game tokens the sister has.
Explanation:The question asks to express the number of game tokens your friend has in terms of 'T', the number of game tokens your sister has. As the information provided states, your friend has '5 more than twice' the amount which your sister has.
The mathematical expression for this will be '2T + 5', where 2T is twice the number of tokens your sister has and 5 is the extra tokens your friend has over twice your sister's total.
So, if your sister has 'T' number of game tokens, your friend will have '2T + 5' number of game tokens.

Assuming the lines are parallel, then refer to the image attachment for the angle labels
A = 14-4x
B = A = 14-4x
C = 5y-9
D = 8y+42
E = 180 - D = 180 - (8y+42) = -8y+138
B+C = 90
(14-4x)+(5y-9) = 90
-4x+5y+5 = 90
-4x+5y = 85
If the lines are parallel, then
A = E
14-4x = -8y+138
-4x+8y = 124
The system of equations is
-4x+5y = 85
-4x+8y = 124
Subtract equation 2 from equation 1 to get
-3y = -39
y = 13
Then use that y value to find x
-4x+8y = 124
-4x+8*13 = 124
-4x+104 = 124
-4x+104-104 = 124-104
-4x = 20
x = -5
So the final answer is x = -5

Jin’s pays 3.48 for a bag of 12 tangerines find the unit price in dollars per tangerine if necessary round your answer to the nearest cent
Answers
Answer:
0.29
Step-by-step explanation:
Final answer:
To find the unit price of tangerines Jin bought, divide the total cost of $3.48 by 12. This gives a unit price of $0.29 per tangerine.
Explanation:
To find the unit price of the tangerines that Jin purchased, you need to divide the total cost by the number of tangerines.
Jin paid $3.48 for a bag of 12 tangerines. Therefore, to calculate the price per tangerine, use the following equation:
Unit Price = Total Cost / Number of Units
Unit Price = $3.48 / 12 tangerines
Unit Price = $0.29 per tangerine
If necessary to round to the nearest cent, the unit price remains $0.29 since it is already at the cent level.

Step-by-step explanation:

*see attached image*
The sides of the triangle formed measure 8 and 2, so by pythagoras, the unknow side [tex]x[/tex] wich is the distance between the houses is:
[tex]x^2=8^2+2^2\\x^2=64+4\\x^2=68\\x=\sqrt{68}=\sqrt{4*17}=2\sqrt{17}[/tex]
So the distance, on the grid, between Joe’s house and Andy’s house is [tex]2\sqrt{17}[/tex]
