A jar holds no more than 500 buttons. If 5 people bring 330 buttons each, how many jars are necessary to hold all of the buttons?

Answer:

The slope of this line is 3.

Step-by-step explanation:

Solve 12x - 4y = 3 for y to obtain the equation in slope-intercept form:

Add 4y to both sides, obtaining 12x = 3 + 4y

Subtract 3 from both sides:  12x - 3 = 4y

Finally, divide all terms by 4:  y = 3x - 3/4

The slope of this line is 3.

Answer:  The slope of the graph is 3.

Step-by-step explanation:

The equation of a line in slope intercept for is given by :-

[tex]y=mx+c[/tex], where m is the slope of the line.

The given equation of  the line graphed by Helaine = [tex]12x - 4y = 3[/tex]

Now, rewrite the above equation in slope-intercept form by adding 4y  and  subtracting 3 from both sides , we get

[tex]4y=12x-3[/tex]

Divide 4 on both sides , we get

[tex]y=3x-\dfrac{3}{4}[/tex] which is the slope-intercept form.

[tex]\Rightarrow\text{Slope}=3[/tex]

Hence, the slope of Helaine's line =3

Answer:

283cm³

Step-by-step explanation:

The linear scale factor= Height of larger/Height of smaller cylinder.

=8cm/4cm=2

VOLUME scale factor = linear scale factor³

=2³=8

Therefore we divide the volume of the larger cylinder by  the volume scale factor.

volume of small cylinder=2264cm³÷8

=283cm³

Answer: first option.

Step-by-step explanation:

 You know that the height of the smaller cylinder is 4 cm and the height of the  larger cylinder is 8 cm, then you can find the volume ratio. This  is:

[tex]Volume\ ratio=(\frac{4\ cm}{8\ cm})^3\\\\Volume\ ratio=\frac{1}{8}[/tex]

Knowing that the volume of the larger cylinder is 2,264 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{8}(2264\ cm^3)\\\\V_{smaller}=283\ cm^3[/tex]

For a given trapezium ABCD, measure of angle [tex]D = 52\°[/tex].

" An angle is defined as when two rays meet at a common point known as vertex."

According to the question,

Given trapezium ABCD,

Measure of angle [tex]BAD= 128\°[/tex]

Measure of angle [tex]ABC= 126\°[/tex]

Measure of angle [tex]BCD= 54\°[/tex]

Sum of all the interior angles in a trapezium is equal to [tex]360\°[/tex].

Therefore,

[tex]\angle ABC + \angle BCD +\angle CDA + \angle DAB = 360\°\\\\\implies 126\°+54\°+ \angle CDA + 128\°=360\°\\\\\implies \angle CDA = 360\° - 308\°\\\\\implies \angle CDA = 52\°[/tex]

Hence, Option (A) is the correct answer.

Final answer:

To solve the equation 4x = 8x - 1, isolate the variable x by subtracting 4x from both sides, then add 1 to both sides, and finally divide both sides by 4. The solution is x = 1/4.

Explanation:

To solve the equation 4x = 8x - 1, we need to isolate the variable x. We can do this by subtracting 4x from both sides of the equation:

4x - 4x = 8x - 4x - 1

0 = 4x - 1

Next, we can add 1 to both sides of the equation:

1 = 4x - 1 + 1

1 = 4x

Finally, we can divide both sides of the equation by 4 to solve for x:

1/4 = 4x/4

x = 1/4

The solution to the equation 4x = 8x - 1 is x = 1/4. We solve the equation by isolating x through standard algebraic steps. Checking our solution, we substitute it back into the original equation and confirm it is correct by verifying the equality.

The equation given by the student is 4x = 8x − 1. To find the value of x, we need to solve the equation. We start by subtracting 4x from both sides of the equation to get 0 = 4x − 1. We then add 1 to both sides which gives us 1 = 4x. Finally, we divide both sides by 4 to isolate x, which results in x = 1/4. This is the solution to the equation.

As a check, substituting x = 1/4 back into the original equation yields 4(1/4) = 8(1/4) − 1, simplifying to 1 = 2 − 1, which is a true statement and confirms our solution is correct.

Using the same technique, we can also solve different algebraic equations or systems of equations by manipulating the equations algebraically before substituting numerical values. This is illustrated in the given set of equations where variables are systematically eliminated until we end up with a single variable.

Therefore the by solving the equation 4x = 8x - 1 we get x = 1/4

= 1.

c.  Function  B : Rate of change =

(0.5 - (-1)) / (3-2)

= 1.5.

d.  Function B increases faster between x = 2 and x = 3.

Answer:

A). (2, -1)

B). Average rate of change of function A = 1

C). Average rate of change of function B = 1.5

D). Graph of function B increases faster than function A.

Step-by-step explanation:

A). vertex of the function A will be (2, -1)

and vertex of the function B will be same as function A, (2, -1)

B). Average rate of change in function A between x = 2 and x = 3 will be

[tex]\frac{f(3)-f(2)}{x-x'}[/tex]

Equation of the function A will be f(x) = (x - 2)²-(-1)

f(x) = (x - 2)² + 1

f(3) = (3 -2)² + 1

     = 1² + 1 = 2

f(2) = 0 + 1 = 1

Therefore, rate of change = [tex]\frac{2-1}{3-2}[/tex]=1

C). Average rate of change of function B will be

=[tex]\frac{f(3)-f(2)}{x-x'}[/tex]

=[tex]\frac{0.5+1}{3-2}[/tex] [ from the given table]

= 1.5

D).Since rate of change of graph B is greater than graph A therefore, function B will increase faster than function A.

The center is at the origin so (h,k) = (0,0) and  the radius is 6 so r=6

x^2 + y^2 = 6^2

or x^2 +y^2 = 36

Answer:

A. [tex]x^2+y^2=36[/tex]

Step-by-step explanation:

An equation of a circle form is: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Step-by-step explanation:

y = 2/27 x² − 4/3 x

a) The leading coefficient (the coefficient of the x² term) is positive, so that means the parabola points up.  So the vertex is at the bottom of the parabola, making it a minimum.

b) For a parabola y = ax² + bx + c, the x coordinate of the vertex can be found at x = -b / (2a).  Here, a = 2/27 and b = -4/3.

x = -(-4/3) / (2 × 2/27)

x = (4/3) / (4/27)

x = (4/3) × (27/4)

x = 9

c) To find the y coordinate of the vertex, we simply evaluate the function at x=9:

y = 2/27 x² − 4/3 x

y = 2/27 (9)² − 4/3 (9)

y = 6 − 12

y = -6

d) The ordered pair is (9, -6).  This means that at the lowest point of the dish, the dish is 6 inches deep.  Also, since the dish is symmetrical, and the lowest point is 9 inches from the end, then the total width is double that, or 18 inches.

The vertex of the function is a minimum point. The x and y-coordinates of the vertex are 27 and -54 respectively, representing the deepest point in the dish where signals are concentrated.

a) The vertex of a parabolic function y = ax^2 + bx + c is a maximum point if 'a' is negative and a minimum point if 'a' is positive. In this case, we have a = 2/27, which is positive, so the vertex of the function is a minimum point.

b) The x-coordinate of the vertex can be found using the formula -b/2a. For the quadratic function y = 2/27x^2 - 4/3x, b = -4/3, and a = 2/27. So the x-coordinate of the vertex is -(-4/3)/(2*2/27) = 27.

c) The y-coordinate of the vertex can be obtained by substituting the x-coordinate of the vertex into the equation. Therefore, y = 2/27*(27)^2 - 4/3*27 = -54

d) So the vertex, as an ordered pair (x, y), is (27, -54). The vertex represents the shallowest point in the parabola, which in the case of a satellite dish, equates to the deepest point of the dish, where signals are most concentrated or focused.

Answer:

Plain still in air = 240

Air current = 28

Step-by-step explanation:

To find the speed of the jet in still air and the speed of the wind, we can set up a system of equations using the given information. Solving these equations, we find that the speed of the jet in still air is 88 mph and the speed of the wind is 180 mph.

To find the speed of the jet in still air and the speed of the wind, we can set up a system of equations using the given information. Let's say the speed of the jet in still air is x mph and the speed of the wind is y mph. When the jet is flying with a tailwind, the speed of the jet relative to the ground is x + y mph. We can write the equation as 1,072 = (x + y) * 4. Similarly, when the jet is flying into a headwind, the speed of the jet relative to the ground is x - y mph. We can write the equation as 848 = (x - y) * 4. Now, we can solve these two equations to find the values of x and y.

Multiplying the first equation by 4, we get 4,288 = 4x + 4y. Subtracting the second equation from this, we get 1,440 = 8y. Dividing both sides by 8, we find that y = 180. Substituting this value back into the first equation, we get 1,072 = 4x + 4 * 180. Simplifying, we get 1,072 = 4x + 720. Subtracting 720 from both sides, we find that 4x = 352. Dividing both sides by 4, we find that x = 88.

Therefore, the speed of the jet in still air is 88 mph and the speed of the wind is 180 mph.
