Answer: $210

Step-by-step explanation:

Answer:

The problem implies that we want to write the (average) amount of natural sweeteners consumed per person as a function of time. Let y represent the (average) amount of natural sweeteners consumed per person (in pounds), and let x represent the time measured in years since 1990. That is, x = 0 represents 1990. If y is a linear function of x, then we can use the slope-intercept form y = mx + b (where m is the slope and b is the y-intercept) to write the function.

 The slope can be interpreted as the rate of change of y with respect to x, which in this case means the change in consumption of natural sweeteners per year. The statement that consumption has decreased by 0.6 pounds per year tells us that the slope is m = -0.6  Also, the y-intercept is the same as the y-value of the function when x = 0. (In our case, that means time 0, that is, 1990.) Therefore the y-intercept is b = 133. Hope that helps! Let me know if you have any further questions.

Answer:

Explanation:

There is a theorem in geometry that says:

In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.

Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.

If they are equal and

arc AB = arc CB

arc AB = 24 feet

Then

arc CB = 24 feet

by substitution.

Answer:

25GB was used that month

Step-by-step explanation:

Here, we want to calculate the GB used for the month.

Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.

The extra charges is thus $75.99 - $59.99 = $20

Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5

So the total GB for that month is 20 + 5 = 25GB

Answer:

v=−1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−14−7(9v+3)=13v+41

−14+(−7)(9v)+(−7)(3)=13v+41(Distribute)

−14+−63v+−21=13v+41

(−63v)+(−14+−21)=13v+41(Combine Like Terms)

−63v+−35=13v+41

−63v−35=13v+41

Step 2: Subtract 13v from both sides.

−63v−35−13v=13v+41−13v

−76v−35=41

Step 3: Add 35 to both sides.

−76v−35+35=41+35

−76v=76

Step 4: Divide both sides by -76.

A fraction between that is 2311/3740

Step-by-step explanation:

This is because the denominator is simplified into one number and the fraction is taken from there.

55 = 5×11

LCM = 2×5×11×17 = 1870

⁵⁵⁾21/34 = ²⁾1155/1870 = 2310/3740

³⁴⁾34/55 = ²⁾1156/1870 = 2312/3740

2310/3740 < 2311/3740 < 2312/3740

Answer:

Y=-7

Step-by-step explanation:

The solution to the equation -3y = 21 is y = -7.

To solve the equation -3y = 21 using inverse operations, we want to isolate the variable y by performing the inverse operation.

Now, the inverse operation of multiplication by -3 is division by -3.

By dividing both sides of the equation by -3, we can isolate y.

Let's perform the inverse operation:

(-3y) / -3 = 21 / -3

y = -7

Therefore, the solution to the equation -3y = 21 is y = -7.

Answer:

1/3 ( 5y-2) = x

Step-by-step explanation:

5y = 3x+2

Subtract 2 from each side

5y -2 = 3x+2-2

5y-2 = 3x

Divide each side by 3

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

1/3 ( 5y-2) = x

Answer:

7

Step-by-step explanation:

Note the relation between x and y

The values of y are 2 less than the corresponding values of x, that is

x = - 3 → y = - 3 - 2 = - 5

x = 0 → y = 0 - 2 = - 2

x = 1 → y = 1 - 2 = - 1

x = 5 → y = 5 - 2 = 3

Thus

x = 9 → y = 9 - 2 = 7 ← missing value

Answer: x = 9.8181......

Answer:

y = -3  x = 7

Step-by-step explanation:

3x cancels.

7y = -21

y = -3

Substitute y in 2y - 3x = -27

2(-3) - 3x = -27

-6 - 3x = -27

-3x = -21

x = 7

We want to find equations for changes of units, which allow us to change the units of a given measure to an equivalent value.

a) [tex]C = H*\frac{2c} {9h}[/tex]

b) [tex]P = H*\frac{6p}{45h}[/tex]

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

We know two relations:

a) We want to find an equation to express the relationship between hands, h, and cubits, c.

Let's start with the relation:

9 hands = 2 cubits

we can rewrite:

[tex]1 = (2 c)/(9 h)[/tex]

Now suppose that we have a measure in hands, H.

If we multiply this measure by 1, we do not affect the measure, then we have:

[tex]H = H*1 = H*\frac{2c}{9h}[/tex]

Notice that we are dividing by hands, so we are cancelling the hands units, and we are multiplying by cubits, so we changed the units.

Then we can define C as the equivalent measure to H, such that C is in cubits.

[tex]C = H*\frac{2c}{9h}[/tex]

b) Similar to before.

Again, let's use H as a measure in hands.

With the relation:

[tex]C = H*\frac{2c}{9h}[/tex]

We change from hands to cubits.

Now with:

5 cubits = 3 paces.

We can write:

1 = 3p/5c

If we multiply our measure in cubits by the above fraction, we can change the units from cubits to paces, so we will have that P, the equivalent measure to H in paces is given by:

[tex]P = C*\frac{3p}{5c} = H*\frac{2c}{9h}*\frac{3p}{5c}= H*\frac{6p}{45h}\\\\P = H*\frac{6p}{45h}[/tex]
