What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of constant of variation

When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion      —-- 1

Given relation is y - 6x = 0

y = 6x

On comparing it with equation 1, we get,

k = 6

Solving for the least common multiple (LCM), the least numbers of packs you should buy in order to have the same numbers of hot dogs and buns is 4 packs of hotdogs and 5 packs of buns.

A common multiple is defined as a whole number, that is a shared multiple of each set of numbers. The least common multiple (LCM) of two integers is the smallest positive integer that is divisible by both numbers.

If hot dogs come in packs of 10, while buns come in packs of eight, solving for their LCM,

10 : 10, 20, 30, 40, 50, . . .

8 : 8, 16, 24, 32, 40, 48, . . .

LCM = 40

Considering 40 hotdogs and 40 buns, dividing each by 10 and 8, the number of packs of each will be:

According to the question, the given data are as follows:

Zoe’s distance = ZZ(miles); Stadium time = tt (hours); Mackenzie’s distance = MM(miles)

Distance between Zoe and stadium = 249 miles

Distance between Mackenzie and stadium = 237 miles

Zoe speed = 58 miles per hour

Mackenzie speed = 55 miles per hour

Time = 2 hours

Using standard distance formula:

Distance = (speed)(time)

As per relative speed, distance gets added and speed gets subtracted when objects are away or parallel from each other.

ZZ = 249 -58tt

MM = 237 -55tt

When both are at the same distance, the time will be t = 4 hours

249 -58tt = 237 -55tt

The probability will:

a) Increase.

b) decrease.

c) increase.

We know that as larger is the size (or the diameter at least) of the hole, the easier will be to lading the skee ball on that hole.

So "If the size of the 40-point hole is enlarged, the probability... "

If you increase the size, then it will be easier to land the ball, thus we can conclude that the probability will increase.

" If the 40-point hole is made smaller, the probability..."

Opposite as the case above, this time will be harder to land the ball, thus the probability will decrease.

"If the 40-point hole stays the same size, but the scoring zone is made smaller, the probability..."

If the ball is thrown in a random way, such that the probability of landing in any region of the scoring zone is the same, then the probability of landing on the 40-point hole is equal to the quotient between the area of the hole and the total area of the scoring zone.

Thus, is you decrease the area of the scoring zone, then the probability increases.

Answer:

Point (0, 0) satisfies the inequalities

Step-by-step explanation:

Sometimes graphing is the best way to determine where the region is that satisfies both inequalities. Then you can choose a point accordingly

The graph of both inequalities is attached. The heavily shaded region in blue represents the region that satisfies both inequalities

If you look at the graph, you can see that (0, 0) falls in the heavily shaded region and therefore it satisfies both constraints

Indeed at (0, 0)

7(0) + 2(0) = 0 which is > -4 since 0 is greater than all negative numbers

Also
-5(0) + 6(0) = 0 which is indeed ≤ 6

So one point is (0, 0)

The line q passes through (2, 0) and (-7, -4)

If line Q does not intersect the line LM, then these lines are parallel, thus, have the same slope.

The slope of line LM is given by:

s = (3 + 4)/(2 + 4) = 7/6

Now we know that the line Q contains point N (2, 0) ( i will assume is this because in the image the points don't have the correspondent names).

Then the line also passes through another point (a, b) such that:

s = (0 - b)/(2 - a) = 7/6

Then:

Energy and mass are related by the formula, E = mc², where m is the mass of the object and c is the speed of light. The equation that finds m, given e and c, is:   m = E/c²

The equation, E = mc² was coined from Albert Einstein's theory of relativity, which shows the relationship between mass and energy. It shows that energy and mass can be interchanged into each other. The equation tells us that if we multiply the mass of a body (m) with the square of the speed of light (c²), we will get the total amount of energy (E) contained in that body, which can potentially be converted to other forms of energy.

However, if are given the energy contained in a body and the speed of light, then told to find the mass of the body, we will divide the equation by the coefficient of m. The coefficient of m in the equation is c², thus:

                          E = mc²

                          E/c² = mc²/c²

   c² divided by c² is 1, therefore, the new equation is:

                               m = E/c²

 Thus, the equation that finds m, given e and c is m = E/c².

The equation of the line in point-slope form, which passes through the pair of points located at (3/2 , -1/2) and (-2/3 , 1/3), is y + 1/2 = -5/13(x - 3/2).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (3/2 , -1/2) and (-2/3 , 1/3).

m = (y2 - y1)/(x2 - x1)

m = (1/3 - -1/2)/(-2/3 - 3/2)

m = (5/6)/(-13/6)

m = -5/13

Using the point slope form, plug in the values of the slope and one point to set up the equation.

(y - y1) = m(x - x1)

where m = -5/13 and (x1 , y1) = (3/2 , -1/2)

(y - -1/2) = -5/13(x - 3/2)

y + 1/2 = -5/13(x - 3/2)
