For solving this problem we have to know the transformations between feeds and kilometers and seconds to hours:
[tex]\begin{gathered} 1\operatorname{km}=3280.84ft \\ 1h=3600\text{ seg} \end{gathered}[/tex]Now we can make the transformation:
[tex]60\frac{ft}{seg}=60\frac{1}{3280.84}\frac{3600}{1}=65.8\frac{\operatorname{km}}{h}[/tex]define what is absolute
We will have that Absolute Value is the magnitude of a value and is denotated as follows:
| x | : The absolute value of x.
When we speak about magnitude we refer just to possitive values. For example:
*The absolute value of 3:
| 3 | = 3
*The absolute value of -45:
| -45 | = 45
From this, we can clearly see that we "keep the number" but not the sign.

What is the perimeter in centimeters of triangle JKL
The perimeter of JKF is 28 cm.
What is perimeter?
The perimeter of a triangle is the distance around it, which is the sum of the lengths of its sides. The formula for the perimeter of a triangle is: Perimeter = a + b + c where a, b, and c are the lengths of the three sides of the triangle.
Given, triangle JKL and DEF is similar.
If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
Given,
perimeter of triangle DEF =28 cm
10 + 6+ third side = 28
third side = 12
Hence,
using the property of similar triangle,
perimeter of DEF/perimeter of JKL = DF/JL
28/ x = 12/4.5
28/x = 2.6
x/28 = 1/2.6
x = 28/2.6
x = 10.7 cm
The perimeter of triangle JKL = 10.7 cm

Answer:
85
Step-by-step explanation:
There is a property of angle of triangles.
Exterior angle = Sum of opposite interior angles
7x + 8 = 3x - 9 + 61
7x + 8 = 3x + 52
7x - 3x = 52 - 8
4x = 44
x = 44/4
x = 11
m∠WHG = 7x + 8
= 7 ( 11 ) + 8
= 77 + 8
m∠WHG = 85
Answer:
Angle WHG is 85 degrees.
Step-by-step explanation:
X = 11.
7(11) + 8 = 85.
180 - 85 = 95 (Angle FHG.)
3(11) - 9 = 24 (Angle GFH.)
A triangle's angles always add up to 180 degrees.
24 + 95 + 61 = 180.
To double check, 180 - 95 = 85 degrees.
I hope this helped! And as for finding X, I kind of forgot how to get X, so I tried X being number 5-10 first, then tried 11, and it worked. Sorry for the late response.

The solution for the equation would be (-4,-16) as the definition of solution of equation says "A number that can be entered for the variable to produce a true number statement is the solution to an equation".
What is solution to equation?A number that can be entered for the variable to produce a true number statement is the solution to an equation. One-step equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing. In an equation, both sides will remain equal if we add the same amount to each side. Systems of equations can be solved using one of three techniques: graphing, substitution, or elimination. Simply plot the given equations on a graph and locate the point(s) where they all intersect to solve a system by graphing. You can find the values of the variables you are solving for by finding the coordinate of this point.
The equation is,
y=4x
x+y=-20
x+4x=-20

A plane traveled 1160 kilometers to Havana and back.
The trip there was with the wind. It took 10 hours.
The trip back was into the wind. The trip back took 20 hours.
What is speed, distance, and time?
The formula speed distance time is used to explain the relationship between speed, distance, and time. That is speed = time/distance. To put it another way, distance divided by speed equals time. You can figure out the third input if you know the first two.
Consider,
s = plane speed in still air
w = speed of the wind
then
(s+w) = ground speed with the wind
and
(s-w) = ground speed against the wind:
A dist equation for each way (dist = speed * time)
10(s+w) = 1160
20(s-w) = 1160
Simplify divide the 1st equation by 13, and the 2nd equation by 26, and you have:
s + w = 116
s - w = 58
Using adding s & eliminates w,
2s = 174
s = 174/2
s = 87 km plane speed in still air
The wind speed
87 + w = 96
w = 9 km is the wind speed
Hence, the speed of the plane in still air is 87 kilometers, and the speed of the wind is 87 kilometers.

How much root beer can they make?
Answer:
1/4
Step-by-step explanation:
Answer:
1/4 barrel of root beer
Step-by-step explanation:
4 pounds of sassafras = 1 barrel of root beer
algebraically, this is 4s = 1r
divide both sides by 4
1s = 1/4r
so 1 pound of sassafra can make 1/4 barrel of root beer
Passes through the x-intercept of 2x - 3y = 6 and parallel to x + 4y = -3
The equation of the line passes through the x intercept of 2x - 3y = 6 and parallel to x + 4y = -3 is y = (-1/4)x + 3/4 .
In the question ,
it is given that ,
the required line is parallel to x + 4y = -3 ,
x + 4y = -3
4y = -x -3
dividing both sides by 4 , we get
y = (-1/4)x -3/4
the slope is -1/4 .
the required line passes through the x intercept of 2x - 3y = 6 .
for x intercept , put y=0 ,
we get
2x -3(0) = 6
2x = 6
x = 6/2
x = 3
the point is (3,0) .
The equation of the line passing through the point (3,0) and the slope -1/4 is
(y-0) = (-1/4)(x-3)
y = -1/4(x - 3)
y = (-1/4)x + 3/4
Therefore , the equation of the line passes through the x intercept of 2x - 3y = 6 and parallel to x + 4y = -3 is y = (-1/4)x + 3/4 .

The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.
What is a rectangle?A rectangle is a type of parallelogram that has equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
The dimensions of the given rectangle are (650 - 2x) and x.
Then, the area of the given rectangle can be written in terms of x as
A(x) = x(650 - 2x)
In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,
(660 - 2x) - 2x = 0
=> 4x = 660
=> x = 660 / 4
=> x = 115
Now, the maximum area is the value of A(x) at x = 115 as below,
= 115 × (650 - 2×115)
= 115 × 320
= 36800
The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.
Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

complementary angles. If m/A= (5x - 11)° and
ZA and ZB are
m/B = (6x + 2)°, then find the measure of ZA.
PLEASE ANSWER ASAP !!!!
Answer:
∠ A = 34°
Step-by-step explanation:
complementary angles sum to 90° , then
5x - 11 + 6x + 2 = 90
11x - 9 = 90 ( add 9 to both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
∠ A = 5x - 11 = 5(9) - 11 = 45 - 11 = 34°
I graphed a parallelogram. Now I need to show that the diagonals bisect each other, or have the same midpoint. What does this mean?
A biscetor is a line that curs another one exactrly at its midpoint. If the diagonals of the paallelogram bisect each other, this means that both cut the other in exact halves.
For example
For the square ABCD, its diagonals BD and AC cut each other in point M.
M is their midpoint, which means that the haves of each diagonal are the same:
For diagonal AC you get that AM=MC
For diagonal BD you get that BM=MD
This means that the diagonals bisect each other and have the same midpoint M
Find the value of the discriminant, the number and types of solution(s). 2x2−6x−15=−7
The equation has 2 irrational roots and two real distinct solutions.
What is a real distinct solution?It is a solution to an equation that occurs only once and differs in value from other solutions. If the discriminant is zero, there are no real solutions. The discriminant equation is Δ = b² - 4ac. If the discriminant is greater than zero it has two irrational roots. Another alternative for a distinct solution is the coincident solution. The values of the discriminant show how many roots and solutions the equation may contain.
Given, 2x² - 6x - 15 = - 7
The discriminant of the equation is D = b² - 4ac
Here, a = 2, b = - 6, c = - 15
D= 36 - 4(2)(-15)
36 + 120 = 156
Here, D > 0 and it is not a perfect square.
