Answer:

  y = 4x

Step-by-step explanation:

You want an equation that represents the proportional relationship between ounces of chocolate (x) and ounces of almonds (y) when we know (x, y) = (2, 8).

A proportional relation can be written using the equation ...

  y = kx

where k is a constant.

The value of k can be found if a pair of values is known for x and y.

  k = y/x . . . divide by x

  k = 8/2 = 4 . . . . use (x, y) = (2, 8) from the table.

The equation for the relationship is ...

  y = 4x

The proportional relationship that accounts between the amount of dark chocolate and the amount of almonds is y = 4x.

What is ratio and proportion?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. An equation known as proportion shows that the two ratios presented are equal to one another. A ratio is the comparative or condensed form of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.

Given, for 2 ounces of dark chocolate(x), 8 ounces of almonds(y) are put in.
Taking the ratio as y to x, we have:
y/x = 8/2 ⇒ y/x = 4 ⇒ y = 4x
Thus, the proportional relationship that accounts between the amount of dark chocolate and the amount of almonds in each package of Sweet and Salty trail mix is y = 4x.

Answer:

Step-by-step explanation:

[tex]=-\frac{12}{15} + -\frac{5}{15} + \frac{12}{15} + \frac{35}{15} \\=\frac{30}{15} \\= 2[/tex]

Answer:

39/15

Step-by-step explanation:

-4/5+-1/3+1 2/5+7/3

Convert all to fractions having the least common denominator.  The mixed denominators of 3 and 5 could be converted to denominators of 15, thereby allowing them to be numerically combined.

-4/5+-1/3+1 2/5+7/3

(-4/5)(3/3) = -12/15

(-1/3)(5/5) = -5/15

(+1 2/5) = (5/5 + 2/5) = (7/5)(3/3) = 21/15

(7/3)(5/5) = 35/15

Since we have a common denominator (15) we can now sum the individual fractions by adding their numerators:

-12 -5 + 21 + 35 = 39

Now add back the denominator

The result is 39/15

The factorized expression is (4/x³)(1/x² + 4).

Step-by-step explanation:

the amount of vertical change in your position when you drive 200 feet is 16 feet

you are driving on a road that has a 8% uphill grade.

this means that the slope of the road is 8/100.

approximate the amount of vertical change in your position when you drive 200 feet

Therefore our proportion is: (where x is the "vertical" rise)

Slope is defined as rise so

The exponent of a number shows how many times the number is multiplied by itself.

For example, 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power." In general, [tex]x^n[/tex] means that x is multiplied by itself for n times.

Given:

[tex]a^{-3} / b ^{-2[/tex]

Round to 1 significant figure

What is Rounding?

To estimate a certain number in a context, rounding is a process. Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up. The term "rounding decimals" describes the accurate rounding of decimal figures.

How to round a figure

It rounds to the most important figure in the number. To round to a significant figure: look at the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.

To understand this term lets take and example:

24982 correct to 1 significant figure

If we round up, then the answer is

30,000

but if we were to round down, the answer would be

20,000;

If we want to determine which one is correct, we have to look at the second digit of the original number, which is

4

Since the second digit is less than 5

we can round down, so the answer would have to be

20,000

Hence, 24982 round to 1 significant figure is 20,000

Answer:20 in * (12 in - 2X in) * (X in) = 360 in3

This can be simplified by dividing both sides by 20 in:

20 in * (12 in - 2X in) * (X in) = (360 in3/ 20 in)

After dividing both sides by 20 in:

(12 in - 2X in) * X in = 18 in2

Distribute X in. across (12 in -2X in):

12X in2 - 2X2 in2 = 18 in2

1.Subtract 18 in2 from both sides:

12X in2 - 2X2 in2 - 18 in2 = 0

2. Rearrange the equation:

-2X2 in2 + 12X in2 - 18 in2 = 0

Answer:

Step-by-step explanation:

In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y and an x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system. To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis. When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable.  For example In algebra, 2-dimensional coordinate graphs have a horizontal axis, or x-axis, and a vertical axis, or y-axis. The places where lines representing a range of values cross these axes are called intercepts. The y-intercept is the place where the line crosses the y-axis and the x-intercept where the line crosses the x-axis. For simple problems, it is easy to find the x-intercept by looking at a graph. You can find the exact point of the intercept by solving algebraically using the equation of the line.

The function formula of the mass of the bottle to the function of the volume of the oil is M = 590 - 0.95V

The glass bottle filled with oil weighs 590 grams.  

After Sophia uses 200 millilitres of oil, the bottle of oil weighs 400grams.

Therefore, the weight M of the bottle of oil in grams is a function of V, the volume, in millimetres of oil Sophia has used.

Therefore, the formula of the function can be represented as follows

density = mass / volume

200 mm reduces the weight of the bottle by 590 - 400 = 190 grams.

V mm will reduce  it to ?

cross multiply

190 × V / 200 = 19 / 20 V = 0.95V

Any number in the form of p/q where q not equal to zero is called as rational Number.

An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational, but π is irrational. The root values will also be irrational.

The number -3 is a rational number. We can write -3 in the form of p/q, i.e  -3/1 where p is -3 and q is 1.

All rational numbers are obtained by dividing one integer by another.

Since it is possible to obtain -3 by dividing the integer

i.e -3 by 1, as in -3/1,

So -3 is a rational number.

Hence -3 is not a irrational number because -3 we can written as a simple fraction.
