The percent decrease in the mass of Finley's pumpkin after carving is approximately 40.55%.

To calculate the percent decrease in the mass of Finley's pumpkin after carving, use the following formula:

Percent Decrease = ((Original Mass - New Mass) / Original Mass) 100%

First, let's find the decrease in mass.

Decrease in Mass = Original Mass - New Mass = 6.56 kg - 3.9 kg = 2.66 kg

Then, calculate the percent decrease:

Percent Decrease = (2.66 kg / 6.56 kg) 100% = 40.55%

The percent decrease in the mass of the pumpkin after carving is approximately 40.55%.

The answer is $11200.

Answer:

C. Both x is a function of y and y is a function of x

Step-by-step explanation:

A function is a relationship which assigns to each input (from the domain) value, a unique output (from the range).

y is a function of x means x is from domain, y is from range

x is a function of y means y is from domain, x is from range

1. Given [tex]y=16-x[/tex]

y is a function of x because for each x there is exactly one y corresponding to this x.

2. Rewrite [tex]y=16-x[/tex] expressing x in terms of y:

[tex]y-16=-x\\ \\-x=y-16\\ \\x=16-y[/tex]

x is a function of y because for each y there is exactly one x corresponding to this x.

Final answer:

In the equation y = 16 - x, both x and y are functions of each other since each variable can be expressed as having a unique output for each input of the other. The correct answer is c. both x is a function of y and y is a function of x.

Explanation:

To determine which statement is true regarding the equation y = 16 - x, we need to understand the concept of a function. A function, in mathematical terms, is a relationship between two sets that assigns to each element of the first set exactly one element of the second set. In simpler terms, for a variable to be a function of another variable, each input should give us exactly one output. This leads us to the vertical line test, which is a visual way to determine if a curve is a graph of a function of x.

Looking at the given equation, y is expressed in terms of x, implying that for each value of x, there is exactly one value of y. This satisfies the definition of a function, so y is a function of x. Conversely, if we solve the equation for x, we get x = 16 - y, which similarly means that for each value of y, there is exactly one value of x, so x is also a function of y.

Given these points, the correct answer is c. both x is a function of y and y is a function of x. This is because each variable can be expressed as having a unique output for each input of the other variable, therefore both variables are functions of each other.

Step-by-step explanation:

The events describe is about picking a card, and placing it back into the deck. This means that the total number of event won't change in each trial.

We know that there are 4 queens of 52 cards. So, the probability of picking a card and be a queen is

[tex]P=\frac{4}{52}=\frac{1}{13}[/tex]

However, in this case, we have to apply the experimental probability definition, because we have several attempts. This experimental probability is defined as the ratio between the time the event occurs (4) and the total number of trials (7). That is

[tex]P_{exp}=\frac{4}{7}=0.57 \ (or \ 57\%)[/tex]

Therefore, the right answer is C.

Ms. Brown has been reading for 18 weeks so far.

To find out how many weeks Ms. Brown has been reading so far, we can set up a proportion based on the rate at which she reads books.

Ms. Brown reads 2 books every 3 weeks, so we can write this as the ratio:

[tex]\[ \frac{2 \text{ books}}{3 \text{ weeks}} \][/tex]

Now, we can set up a proportion to find out how many weeks she has been reading to reach a total of 12 books.

Let ( x) represent the number of weeks she has been reading so far. So, we set up the proportion:

[tex]\[ \frac{2 \text{ books}}{3 \text{ weeks}} = \frac{12 \text{ books}}{x \text{ weeks}} \][/tex]

Now, we can solve for ( x ) by cross-multiplying:

[tex]\[ 2 \times x = 3 \times 12 \][/tex]

[tex]\[ 2x = 36 \][/tex]

Divide both sides by 2 to solve for ( x ):

[tex]\[ x = \frac{36}{2} \][/tex]

[tex]\[ x = 18 \][/tex]

So, Ms. Brown has been reading for 18 weeks so far.

complete question given below:

Ms. Brown is reading 2 books every 3 weeks. She has read 12 books so tar. How many weeks has she been reading so far?

This question is incomplete, here is the complete question:

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

The equation that represents the relationship between the number of euros and the value in dollars is y = 1.125 x

Step-by-step explanation:

On a resent day;

We need to write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars

∵ The form of the equation is y = kx, where x is the number of

   euros and y is the value in dollars

∵  8 euros were worth $9

∴ (8 , 9) is an ordered pair belong to the equation

∵ 24 euros were worth $27

∴ (24 , 27) is another ordered pair belong to the equation

To find k substitute x and y in the equation by the coordinates of one of these two points

∵ x = 8 and y = 9

∵ y = kx

∴ 9 = 8k

- Divide both sides by 8

∴ 1.125 = k

- Substitute the value of k in the equation

∴ y = 1.125 x

To check the equation substitute x by the x coordinate of the 2nd point if it gives the same value of the y-coordinate of the point then the equation is true

∵ x = 24

∵ y = 1.125 x

∴ y = 1.125(24)

∴ y = 27 the same value of the y-coordinate of the point

∴ The equation is true

The equation that represents the relationship between the number of euros and the value in dollars is y = 1.125 x

Answer:

[tex]y\leq -\frac{1}{3}x+1[/tex]

Step-by-step explanation:

Given:

From the graph, the x and y intercepts are at the points (3, 0) and (0, 1) respectively.

Now, for a line with two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex], the slope is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here, [tex](x_1,y_1)=(3,0)\ and\ (x_2,y_2)=(0,1)[/tex]. Therefore,

[tex]m=\frac{1-0}{0-3}=-\frac{1}{3}[/tex]

Now, y-intercept is [tex]b=1[/tex]

Therefore, the standard form of a line is of the form: [tex]y=mx+b[/tex]. So, the equation of the line on the graph is:

[tex]y=-\frac{1}{3}x+1[/tex]

Now, from the graph, the region is below the line including all the points on the line. Therefore, the inequality used is less than or equal to. This gives,

[tex]y\leq -\frac{1}{3}x+1[/tex]

Answer:

m∠NQP=74°

Step-by-step explanation:

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

In this problem

In the triangle NPQ

m∠N+m∠P+m∠Q=180°

we have

m∠N=(2x)°

m∠P=(34)°

m∠Q=(2x+2)°

substitute the values

[tex](2x)\°+(34)\°+(2x+2)\°=180\°[/tex]

solve for x

[tex](4x+36)\°=180\°[/tex]

[tex]4x=180-36[/tex]

[tex]4x=144[/tex]

[tex]x=36[/tex]

Find the measure of angle NQP

we know that

m∠NQP=m∠Q=(2x+2)°

substitute the value of x

m∠NQP=(2(36)+2)=74°

The system of equations is solved using the elimination method. By multiplying the equations to align the coefficients and adding them to eliminate y, x is found to be 3.3333. Plugging x back into one of the original equations then gives y as -2.0000.

To solve the system of equations:

we can use the method of substitution or elimination. Let's use elimination in this case:

First, we multiply the first equation by 4 and the second equation by 3 so that the coefficients of y have the same magnitude but opposite signs:

Next, we add the two equations together to eliminate y:

8x + 12y + 9x - 12y = 8/3 + 54

17x = 54 + 8/3

17x = 54 + 2.6667

17x = 56.6667

Now we divide both sides by 17 to solve for x:

x = 56.6667 / 17

x = 3.3333

With x found, we can now substitute it back into one of the original equations to find y. We'll use the first equation for this example:

2x + 3y = 2/3

Substitute x:

2(3.3333) + 3y = 2/3

6.6666 + 3y = 2/3

3y = 2/3 - 6.6666

3y = -6.0000

Now divide both sides by 3 to solve for y:

y = -6.0000 / 3

y = -2.0000

The solution to the system is x = 3.3333 and y = -2.0000.

Answer:

Damien will receive a change of [tex]\$4.69[/tex]

Step-by-step explanation:

Given:

Pair of jeans = $33

Sales tax = 7%

Money paid as Sales tax = 7% of sale done on pair of jeans  = [tex]\frac{7}{100}\times \$33 = \$2.31[/tex]

Total amount paid = 40

We need to find the amount he will receive back

Amount receive back can be calculated by Total amount paid minus Amount for pair of jeans minus money paid as Sales Tax

Change amount received = Total amount paid - Amount for pair of jeans - money paid as Sales Tax = [tex]\$40 - \$33-\$2.31 = \$ 4.69[/tex]

Hence Damien will receive a change of [tex]\$4.69[/tex]

If jay has been working for his current company for 15 years, then his age is 40 years.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, jay spent 3/8ths of his life working for a company and he has been working for his current company for 15 years.

Assuming Jay's age to be x years.

∴ (3/8) of x is 15 years.

(3/8)x = 15.

x = 15×(8/3).

x = 40.

So, Jay's age is 40 years.

Good evening ,

Step-by-step explanation:

we know that, x-1 = (-1)×(1-x) and 1-x=(-1)×(x-1)

then each of 1-x and x-1 is a multiple of the other one,

if x>1 then x-1>0 and 1-x<0 then x-1>1-x

therefore in this case the least common multiple of x-1 and 1-x is x-1.

if x<1 then x-1<0 and 1-x>0 Then 1-x>x-1

Answer:

k = 4

Step-by-step explanation:

Given that a varies directly as b then the equation relating them is

a = kb ← k is the constant of variation

To find k use the condition a = 8 when b = 2

k = [tex]\frac{a}{b}[/tex] = [tex]\frac{8}{2}[/tex] = 4

Answer:

K = 4

Step-by-step explanation:

Given that varies a directly as b then the equation relating them is

Simply implies that a is directly proportional to b, that is increase in a will cause increase in, and decrease in a will cause decrease in b, and vice versa, where k remains constant.

a α b

a = kb, where k is constant

To find k use the condition a = 8 when b = 2, we make k the subject of the formular

K = a/b

K = 8/2

K = 4
