Anna, Brad, Carly, Deonte, and Elijah ran around a track as
part of a fundraiser for the school’s math club. Anna ran
first, and when she was tires, Brad ran. When Brad got
tired, Carly ran, and so on. By the end of the fundraiser,
they had run a total of 30 miles. Anna and Brad combined
ran 12 miles.
Brad and Carly combined ran 10.2 miles.
Carly and Deonte combined ran 12 miles.
Deonte and Elijah combined ran 12.3 miles.
How far did each person run?

Answer:

4

Step-by-step explanation:

That problem is equal to (2•2•2•2) -(2•2•2+2•2)

Or

16-(8+4)

Answer:

A (4) is your anwser :)

Step-by-step explanation:

1) The equation that has infinitely many solution is y = -8/11·x + 4

2) The equation of the graph that has no solution is y = -8/11·x + 1

3) The equation of the line that has only one solution is y = -1/4·x + 2

Step-by-step explanation:

1) The points on the graph are;

(0, 4), and (5.5, 0)

The slope of the line defined by the given two points, we have;

(0 - 4)/(5.5 - 0) = -40/55 = -8/11

the equation of the straight line graph in point and slope form, we have;

y - 4 = -8/11 × (x - 0)

y - 4 = -8/11·x

For the equation for the system that has infinitely many solution, we have;

y = -8/11·x + 4

2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;

An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal

Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;

y - 1 = -8/11 × (x - 0)

y - 1 = -8/11·x

The equation of the graph that has no solution is therefore;

y = -8/11·x + 1

3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;

The slope of the graph is (1 - 2)/(4 - 0) = -1/4

The equation of the line that has only one solution with the system in point and slope form is given as follows;

y - 2 = -1/4×(x - 0)

y - 2 = -1/4·x

The equation of the line that has only one solution in standard form is therefore;

y = -1/4·x + 2

The second equation for the system so it has infinitely many solutions is [tex]y=-\dfrac{3}{4}x+1[/tex] and the second equation whose graph goes through (0,2) so the system has one solution at (4,1) is [tex]\rm y = -\dfrac{1}{4}x+2[/tex] and this can be determined by using the point-slope form of the line.

Given :

The graph of the line that passes through the points (4,1) and (0,4).

The equation of the line that passes through the points (4,1) and (0,4) is given by:

[tex]\dfrac{y-1}{x-4}=\dfrac{4-1}{0-4}[/tex]

Cross multiply in the above equation.

-4(y - 1) = 3(x - 4)

-4y + 4 = 3x - 12

3x + 4y = 16

[tex]\rm y = 4-\dfrac{3x}{4}[/tex]   --- (1)

a) The second equation for the system so it has infinitely many solutions is given by:

Multiply equation (1) by 2 in order to determine the second equation.

[tex]\rm 2\times \left(y = 4-\dfrac{3x}{4}\right)[/tex]

[tex]\rm 2y = 8 - \dfrac{3x}{2}[/tex]

b) The second equation that passes through (0,1) and has a slope of -3/4 is given by:

[tex](y-1)=-\dfrac{3}{4}(x)[/tex]

[tex]y=-\dfrac{3}{4}x+1[/tex]

c) The second equation whose graph goes through (0,2) so the system has one solution at (4,1) is given by:

[tex]\dfrac{y - 2}{x-0}=\dfrac{1-2}{4-0}[/tex]

Cross multiply in the above equation.

4(y - 2) = -1(x)

4y - 8 = -x

[tex]\rm y = -\dfrac{1}{4}x+2[/tex]

Answer:

Step-by-step explanation:

Answer:

4289 kilometers squared

Step-by-step explanation:

This is an example of compounding. We start with the basic 4800 kilometers of land. We then find seven percent of the 4800 kilometers and subtract that same seven percent. If we are trying to find the area after twelve years, we must repeat this process twelve times. This does not mean that we find seven percent of 4800 then repeat subtracting the same amount. We need to fix the seven percent so that we can get seven percent of the amount we currently have.

With this in mind, we need to write a equation:

[tex]cv = cv/107[/tex]*

*Note that we are trying to find 93% of the current value (cv). We need to divide by 107%, not 7% (would be an illogical divisor). Then, when we divide by 107%, we have the 7% that we need to subtract by. There, we find the needed 93%

Now we can solve.

4800/107 = 45**(1)

4800 - 45 = 4755

4755***/107 = 44**(2)

***As mentioned earlier, we do not continue to subtract 45. We need to adjust to a new current value (cv).

4755 - 44 = 4711

4711/107 = 44**(3)

4711 - 44 = 4667

4667/107 = 44**(4)

4667 - 44 = 4623

4623/107 = 43**(5)

4623 - 43 = 4580

4580/107 = 43**(6)

4580 - 43 = 4537

4537/107 = 42**(7)

4537 - 42 = 4495

4495/107 = 42**(8)

4495 - 42 = 4453

4453/107 = 42**(9)

4453 - 42 = 4411

4411/107 = 41**(10)

4411 - 41 = 4370

4370/107 = 41**(11)

4370 - 41 = 4329

4329/107 = 40**(12)****

****Meaning that this is the last year

4329 - 40 = 4289

Your answer is 4289 kilometers squared.

Hope this helped.

Answer:

Step-by-step explanation:

Since this triangle is a 90 degree angle, all you'd have to do is subtract 55 from 90 and you've got you answer.

Answer:

4.66 or 14/3

Step-by-step explanation:

Area of a triangle is (base × height)/2. They have given you the height and the area already, so:

14 = ( b × 6 ) / 2

28 = b × 6

4.66 = b

The base of the triangle is B = 4.667 feet or 14/3 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the area of the triangle be represented as A

Now , the value of A is A = 14 feet²

Let the height of the triangle be H = 6 feet

Let the base of the triangle be B

And , area of the triangle = ( 1/2 ) x Length x Base

Substituting the values in the equation , we get

14 = ( 1/2 ) x 6 x B

On simplifying the equation , we get

14 = 3B

Divide by 3 on both sides of the equation , we get

B = 14/3 feet

Therefore , the base of the triangle is B = 4.667 feet

Hence , the base of triangle is 4.667 feet
