find the length of arc JM

well, so we know the ratio of compost to soil is 2 : 10, or namely 2/10 which simplifies to 1/5 or namely the ratio of 1 : 5.

the mix will be 6 kgs total, so we'll simply divide the whole amount by (1 + 5), the sum of the ratios, and then distribute accordingly.

[tex]\bf 2:10\implies 1:5\qquad \qquad \cfrac{compost}{soil}\qquad \cfrac{1\cdot ~~\frac{6}{1+5}~~}{5\cdot \frac{6}{1+5}}\implies \cfrac{1\cdot 1}{5\cdot 1}\implies \cfrac{\stackrel{compost}{\boxed{1~kg}}}{5~kg}[/tex]

Answer:

Gabriel Is making a mixture of compost and soil to use for a special plant. He wants his Final mix to be two parts compost to 10 parts potting soil. he wants to end up with 6 kg of mix. How many kg of compost should Gabriel use?

Step-by-step explanation:

We have a total of 12 parts, where 2 are compost, and on the other hand 6 kg which is the total of the whole mixture, divided by 12; 6/12 = 0.5 would be each of the parts, we multiply it by 2; 0.5 x 2 = 1 kg would be the part of compost, and 0.5 x 10 = 5 kg would be the part of potting soil which added, gives us the total 6 kg.

Answer:

all values of b

Step-by-step explanation:

6b < 36 or 2b + 12 > 6.

First solve the one on the left

6b < 36

Divide by 6

6b/6 < 36/6

b  <6

Then solve the one on the right

2b + 12 > 6

Subtract 12 from each side

2b+12-12 >6-12

2b >-6

Divide by 2

2b/2 >-6/2

b >-3

b<6 or b >-3

Rewriting

b>-3  or b<6

b > -3 is an open circle at -3 with a line going to the right

b < 6 is an open circle at 6 with a line going to the left

The or means we add the lines together

We have a line going from negative infinity to infinity

Answer:

All real numbers  b ∈ [tex](-\infty, \infty)[/tex]

Step-by-step explanation:

First we solve the following inequality

[tex]6b < 36[/tex]

Divide by 6 both sides of the inequality

[tex]b<\frac{36}{6}\\\\b<6[/tex]

The set of solutions is:

[tex](-\infty, 6)[/tex]

Now we solve the following inequality

[tex]2b + 12 > 6[/tex]

Subtract 12 on both sides of the inequality

[tex]2b + 12-12 > 6-12[/tex]

[tex]2b> -6[/tex]

Divide by 2 on both sides of the inequality

[tex]\frac{2}{2}b> -\frac{6}{2}[/tex]

[tex]b> -3[/tex]

The set of solutions is:

[tex](-3, \infty)[/tex]

Finally, the set of solutions for composite inequality is:

[tex](-\infty, 6)[/tex]  ∪ [tex](-3, \infty)[/tex]

This is: All real numbers [tex](-\infty, \infty)[/tex]

Answer:

So the x-intercept is (9,0) and the y-intercept is (0,-3).

So I'm going to graph both points and connect them with a straight-edge.

Step-by-step explanation:

I would graph this using it's x- and y-intercepts.

To find the x-intercept, set y=0.

-3x+9(0)=-27

-3x+0=-27

-3x=-27

Divide both sides by -3:

x=9

To find the y-intercept, set x=0:

-3(0)+9y=-27

 0  +9y=-27

       9y=-27

Divide both sides by 9:  

        y=-3

So the x-intercept is (9,0) and the y-intercept is (0,-3).

So I'm going to graph both points and connect them with a straight-edge.

Answer:

The prime factors of 621 are 3*3*3*23 ....

Step-by-step explanation:

Prime factorization is the process of finding that which prime numbers can be multiplied together to make the original number.

Find the prime factors of 621.

Start with the smallest prime number which is 2. If the number is divisible by 2 then solve further. If not then move to the next prime number.

621 is nor divisible by 2

We move towards the next prime number which is 3.

621 divided by 3 = 207

207 divided by 3 = 69

69  divided by 3 = 23

Now 23 is only divisible by 23 which is also a prime number.

Thus the prime factors of 621 are 3*3*3*23 ....

Answer:

y=x

Step-by-step explanation:

We want a line parallel to y =x+42

The slope of y =x+42 is 1

Parallel lines have the same slope

We have the slope m=1 and a point (2,2)

We can use point slope form to write a line

y-y1 = m(x-x1)

y-2 = 1(x-2) point slope form

Changing to slope intercept form

y-2 = x-2

Add 2 to each side

y-2+2 = x-2+2

y=x

The line parallel to y = x + 42 travels through (2,2) can be represented by the equation y = x. This conclusion is based on the principles of line equations in a two-dimensional space, with slopes determining the parallelism of lines.

The subject of the question pertains to the formula of a line in a two-dimensional space. Specifically, you're asked to find a line that passes through the point (2,2) and is parallel to the line described by the equation y = x + 42.

In a standard equation of a line, y = mx + b, 'm' represents the slope of the line and 'b' indicates the y-intercept. Two lines are parallel if they have the same slope. Bearing this in mind, as the line y = x + 42 has a slope of 1 (since 1 is the coefficient of 'x'), the required line would also possess a slope of 1.

Substituting the point coordinates (2,2) into the equation y = mx + b (replacing 'm' with 1), gives us 2 = 2 + b. Solving for 'b', we find that it equals zero. Hence, the equation of a line parallel to y = x + 42 passing through the point (2,2) is y = x.

Step-by-step explanation:

So your set of points I believe is:

(1,4)

(2,2.5)

(3,1)

(4,-0.5)

You are asked to find the average rate of change. This just means find the slope.

So you can make sure the slope is the same per pair of points.

So I like to find the slope by lining two points up vertically and subtracting vertically then put 2nd difference over 1st difference.

(2 , 2.5)

-( 1 ,  4)

----------------

 1,  -1.5

So the slope is -1.5/1 or just -1.5.

Check another pair:

 (3  , 1  )

- (2  ,2.5)

So the slope is -1.5/1 or just -1.5.

Check one more:

There are are 30 possible ways for the 6 students to be ranked 1st and 2nd

Step-by-step explanation:

There are 6 students, and any of them could receive first place. Therefore, there are 6 possibilities for first place.

A student cannot receive first and second place, so the student who won first place cannot also win second place. Therefore, there are only 5 students who could win second place.

We can multiply these two possibilities to find the number of possible rankings of 1st and 2nd

6*5=30

There are are 30 possible ways for the 6 students to be ranked 1st and 2nd....

Answer:

q = -2

Step-by-step explanation:

-2x²-8x = 10 (divide both sides by -2)

x² + 4x = -5 (Apply completing the square method)

x² + 4x + (4/2)²= -5 + (4/2)²

x² + 4x + 2²= -5 + 2²    (reduce left hand side using a²+2ab+b² =  (a+b)² )

(x+2)² = -5 +4

(x+2)² = -1

(x+2)² + 1 = 0   (multiply both sides by -2)

(-2)(x+2)² + 1 (-2) = 0

-2[x - (-2)]² + (-2) = 0  ---> compare this with -2(x-p)² + q = 0

We can see that p = 2 and q = -2

The value of 'q' in the rearranged form of the given quadratic equation -2(x-p)²+q = 0 is -6. This is obtained by completing the square and comparing the equations.

Given the quadratic equation -2x² -8x = 10, it's rearranged to the form -2(x-p)²+q = 0. The objective is to find the value of 'q'.

To achieve this, you first need to rewrite the given equation -2x² -8x - 10 = 0 in the form -2(x-h)²+k = 0. This is called completing the square. The 'h' value here is equal to -b/2a, where 'b' is the coefficient of 'x' and 'a' is the coefficient of x². In this equation, a is -2 and b is -8 so h=(-(-8)/(2×(-2))=8/4=2.

Substituting h into the equation, you have -2(x-2)²+k=0. Now expand and simplify to get -2x²+8x-4+k=0. Comparing this with the original equation -2x² -8x -10 = 0, you can see that 'k' is equal to -10+4=-6, which is the 'q' value in the form -2(x-p)²+q = 0. So, the value of 'q' is -6.

Answer:

C

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.

I can confirm that the answer is right.

Parallelograms have equal opposite sides. Do the math:

x - y = z

40 - 20 = 20

Graph #1

Step-by-step explanation:

Compare your

y - 1 = (2/3)(x - 3) to

y - k = m(x - h).  We see that k = 1 and h = 3.

Thus, (1, 3) is a point on the graph.  This matches Graph #1.  

Note: Graph #1 and Graph #3 appear to be the same.  Why?

The graph of the equation is:

                          Graph 1

The equation is given by:

Step-by-step explanation:    

The segment ¯AB¯  is congruent to the segment ¯BC¯ .

The point is in between the circle.

Therefore, they are congruent.

True. The segment AB is congruent to the segment BC.

If the length of both the line segments are same, then we can say that both the line segments are congruent to each other.

Here, in the given diagram AC is a chord of the circle centering at O.

B is a point on the chord AC.

The radius of the circle which is perpendicular to AC & passes through B,forms right angle at point B.

Since, AC is a chord of the circle & a radius is perpendicular to AC, the the intersecting point of AC & the radius is midpoint of AC.

So, B is the midpoint of AC.

∴ Line segment AB = Line segment BC

Answer:

x = 2

y = 0

Step-by-step explanation:

We can solve using substitution, substitute y in the first equation with the second equation:

-(-6x + 12) + 3x = 6

Distribute the negative sign:

6x - 12 + 3x = 6

Combine like terms:

9x - 12 = 6

Isolate the variable and solve for x by adding 12 in both sides:

9x = 18

x = 2

Substitute 2 with x in any equation to find the value of y:

-y + 3(2) = 6

-y + 6 = 6

Subtract 6 in both sides to isolate the variable:

-y = 0

0/-1 = 0

y = 0

Our answer would be x = 2 and y = 0

Answer:

(2,0)

Step-by-step explanation:

I'm going to use substitution since one of the variables in one of the equation is already solved for.

-y+3x=6

y=-6x+12

I'm going to replace the first y with the second y which is (-6x+12).

This gives me:

-(-6x+12)+3x=6

Distribute:

6x-12+3x=6

Combine like terms:

9x-12=6

Add 12 on both sides:

9x=18

Divide both sides by 9:

x=2

If x=2 and y=-6x+12, then y=-6(2)+12=-12+12=0.

The solution (the intersection) is (2,0).

B. Linear function and a relation

Step-by-step explanation:

The graph is a straight line and by definition a linear function.

Each point on the line can be expressed as an ordered pair i.e  the coordinates (x,y), implying that there is a relation between x and y.

Answer:

B. Linear function and a relation

Step-by-step explanation:

The following terms are defined like so,

Linear: linear functions show up as straigh lines when plotted on a graph

Non-Linear: non-linear functions show up as curvy or wavvy lines when plotted on a graph

Relation: relation graphs have specific outputs for every input, meaning for every x location on the graph there is only one y point.

Based on the definitions above we can determine that the graph in the diagram is both Linear and a Relation, since it is both a straight diagonal line as well as only having one specific y coordinate for every x coordinate. So the answer would be B. Linear function and a relation.

Answer:

The price decreased by 16 1/3%, or approximately 16.3%

Step-by-step explanation:

Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.

percent change = (new price - old price)/(old price) * 100%

In this case, use:

new price = 50

old price = 60

percent change = (new price - old price)/(old price) * 100%

percent change = (50 - 60)/60 * 100%

percent change = -10/60 * 100%

percent change = -1/6 * 100%

percent change = -100/6% = -50/3% = -16 1/3%

The price decreased by 16 1/3%, or approximately 16.3%
