11 grams of fat. What percent of the mayonnaise,
to the nearest tenth of a percent, is fat?

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slopw and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (5, - 1)

m = [tex]\frac{-1-2}{5-3}[/tex] = - [tex]\frac{3}{2}[/tex], thus

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 2), then

2 = - [tex]\frac{9}{2}[/tex] + c ⇒ c = 2 + [tex]\frac{9}{2}[/tex] = [tex]\frac{13}{2}[/tex]

y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{13}{2}[/tex] ← equation of line

Answer:

The equation of the line passing through the given points is

[tex]y=-\frac{3}{2}x+\frac{13}{2}[/tex]

Step-by-step explanation:

GIven two points are (3,2) and (5,-1)

To find the equation of the line passing through these two points

Let [tex](x_{1},y_{1})[/tex] and  [tex](x_{2},y_{2})[/tex] be the two points (3,2) and (5,-1) respectively

Using the two points formula for finding slope:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m=\frac{-1-2}{5-3}[/tex]

[tex]m=\frac{-3}{2}[/tex]

Therefore [tex]m=-\frac{3}{2}[/tex]

By using  formula:

[tex]y=mx+c[/tex]

Here Let (x,y) be (3,2)

[tex]y=mx+c[/tex]

[tex]2=-{\frac{3}{2}}\times 3+c[/tex]

[tex]2=\frac{-9}{2}+c[/tex]

[tex]c=\frac{9}{2}+2[/tex]

[tex]c=\frac{9+4}{2}[/tex]

[tex]c=\frac{13}{2}[/tex]

Therefore substitute values of m and c in

[tex]y=mx+c[/tex]

[tex]y=-\frac{3}{2}x+\frac{13}{2}[/tex]

Therefore the equation of the line passing through the given points is

[tex]y=-\frac{3}{2}x+\frac{13}{2}[/tex]

To find the total number of cookies burnt in the day, which is the whole, we would use the formula 'whole = part / percentage', or 'whole = 439 / 0.25', which gives us 1756 cookies.

The subject of this question is Mathematics, specifically it's a problem on percent. The problem states that 439 cookies represented 25% of all the cookies the employee burnt that day. The question asks us to find the total number of cookies burnt by using this information.

When trying to find the whole from a percent, you can use the formula: whole = part / percentage. In this case, 'part' refers to the 439 cookies, and 'percentage' is 25% expressed as a decimal (0.25).

Using the formula, we find that the total (whole) number of cookies burnt is: whole = 439 / 0.25 = 1756 cookies. So, the new employee burnt 1756 cookies in the course of the day.

Answer:

2 sheets of plywood will be needed.

Step-by-step explanation:

See the attached diagram.

Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square.  {Since each unit on the coordinate plane represents four feet}

Now, the two triangular plywood has area half of a unit square area.

So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.

Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.

Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need [tex]\frac{64}{32} = 2[/tex] such sheets of plywood. (Answer)

The missing figure is attached below.

Answer:

The first image from left.

Step-by-step explanation:

Given:

Rotation of the quadrilateral PQRS by 90 degree counterclockwise around the origin.

We know that, for a 90 degree counterclockwise rotation, the transformation rule for the coordinates is given as:

[tex](x,y)\to (-y,x)[/tex]

So, the 'x' and 'y' interchange their values after rotation and the 'y' value sign is reversed.

Now, let us check each option.

Option 1:

Coordinates of the original quadrilateral are:

P(5, 2.5), Q(1, 4), R(2, 2.5), and S(1, 1)

Now, after rotation by 90 degree counterclockwise, the coordinates of the transformed figure will be:

[tex](x,y)\to (-y,x)[/tex]. So,

P(5, 2.5) → P'(-2.5, 5)

Q(1, 4) → Q'(-4, 1)

R(2, 2.5) → R'(-2.5, 2)

S(1, 1) → S'(-1, 1)

Now, if we check the coordinates of P', Q', R' and S' on the first option, we see that they are same as calculated above. So, the correct option is option 1.

Option 2:

Coordinates of P are (5, 2.5) and coordinates of P' are (2.5, -5) which doesn't match with the transformation rule. So, this option is incorrect.

Option 3:

Coordinates of P are (5, 2.5) and coordinates of P' are (-5, 2.5) which doesn't match with the transformation rule. So, this option is incorrect.

Part 1) The system of equations is

[tex]C=8n+12[/tex] ----> equation 1

[tex]C=10n[/tex] ----> equation 2

Part 2) The graph in the attached figure

Part 3) The number of gym visits must be greater than 6

Step-by-step explanation:

step 1

Find the system of equations that represent the situation

Let

C ----> the total cost in dollars

n ---> the number of gym visits

we know that

The linear equation in slope intercept form is equal to

[tex]C=m(n)+b[/tex]

where

m is the slope or unit rate of the linear equation

b is the C-intercept or initial value of the linear equation

First payment option ---> For Members

we have that

The slope or unit rate is equal to [tex]m=\$8\ per\ gym\ visit[/tex]

The C-intercept or initial value is [tex]b=\$12[/tex] --->one-time registration fee

substitute

[tex]C=8n+12[/tex]

Second payment option ---> For Non-Members

we have that

The slope or unit rate is equal to [tex]m=\$10\ per\ gym\ visit[/tex]

The C-intercept or initial value is [tex]b=\$0[/tex]

substitute

[tex]C=10n[/tex]

we have

[tex]C=8n+12[/tex] ----> equation 1

[tex]C=10n[/tex] ----> equation 2

Part 2) Upload a graph

using a graphing tool

The graph in the attached figure  

Part 3) After how many gym visits is the payment for the member option more beneficial than the payment for the nonmember option?

we know that

If the payment for the member option is more beneficial than the payment for the nonmember option, then the cost for the member option is less than the cost for the nonmember option

so

The inequality that represent this situation is

[tex]8n+12 < 10n[/tex]

solve for n

subtract 8n both sides

[tex]12 < 10n-8n[/tex]

[tex]12 < 2n[/tex]

Divide by 2 both sides

[tex]6 < n[/tex]

Rewrite

[tex]n > 6[/tex]

therefore

The number of gym visits must be greater than 6

The number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

It is given that Karli and her friend can paint 6/7 of a picture in 3/14 of an hour.

Let's assume they can paint x number of pictures in a full hour.

So , the fraction by dividing 6/7 by 3/14 can be written equal to x .

i.e.,

[tex]\frac{6/7}{3/14}[/tex] = x

We need to do the cross product here :

[tex]\frac{3}{14}[/tex] × x = [tex]\frac{6}{7}[/tex]

or

x = ([tex]\frac{6}{7}[/tex]) ÷ ([tex]\frac{3}{14}[/tex])

We know that when dividing two fractions we need to change the division sign to multiplication sign by inverse the fraction value right to the division sign i.e.,

x = ([tex]\frac{6}{7}[/tex]) × ([tex]\frac{14}{3}[/tex])

x = 84 / 21

x = 4

Therefore , the number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

Answer:

The maximum number of packages that can be made  with each package have same number of each item is = 6

Step-by-step explanation:

Given:

Mr. Harris has 48 pencils and 30 notebooks.

To find the number of packages he can make with each package have same number of each item.

Solution:

Number of pencils = 48

Number of notebooks = 30

In order to find the number of packages he can make with each package have same number of each item, we will find the greatest common factor of the given numbers.

To find the G.C.F., we will list down the prime factors of each.

[tex]48=2\times 2\times 2\times 2\times 3[/tex]

[tex]30=2\times 3\times 5[/tex]

We find that the G.C.F. = [tex]2\times 3[/tex] = 6

Thus, the maximum number of packages that can be made  with each package have same number of each item is = 6

Answer:

(a) The equation is [tex]7h-2=56[/tex].

(b) Trey gets approximately $8.29 for each hour of work.

Step-by-step explanation:

Given:

Number of hours Trey works = 7

Amount of money he put aside for mom = $2

Total Amount he keeps each day = $56

We need to find the amount he gets for each hour.

Let 'h'  represent the amount (in dollars) Trey gets paid each hour.

Solving for part (a).

We need to write the equation to find the amount he gets paid for each hour.

Now we can say that;

Total Amount he keeps each day is equal to Number of hours Trey works multiplied by the amount he gets paid for each hour minus Amount of money he put aside for mom.

framing in equation form we get;

[tex]7h-2=56[/tex]

Hence the equation is [tex]7h-2=56[/tex].

Solving for part (b).

we need to solve the above equation to find the amount he gets paid for each hour.

On solving the equation we get;

Adding both side by 2 we get

[tex]7h-2+2=56+2\\\\7h=58[/tex]

Now Dividing both side by 7 using Division Property we get;

[tex]\frac{7h}{7} = \frac{58}{7}\\\\h \approx \$8.29[/tex]

Hence Trey gets approximately $8.29 for each hour of work.

To find: Number of times Pat will bounce the ball in 150 seconds

From given information,

30 seconds = 25 times

Therefore number of times ball bounces in 1 second is:

[tex]\text{1 second } = \frac{25}{30} \text{ times }[/tex]

So to find for 150 seconds, multiply both the sides by 150

[tex]150 \text{ seconds } = \frac{25}{30} \times 150 = 125 \text{ times }[/tex]

Therefore Pat will bounce the ball 125 times in 150 seconds

On this case if we analyze both slopes, we see that function 2 has a greater rate of change because have a slope greater on absolute value than the slope for Function 1 (|-5|>|4|). No matter if the sign is positive or no we are analyzing the rate of change and for this case we need to use the absolute value to find the solution.

Step-by-step explanation:

Assuming the following two functions:

Function 1: y = 4x + 8

Function 2:  

x y

2 20

4 10

6 0

We can find the slope for the second function like this:

[tex]m =\frac{10-20}{4-2}=-5[/tex]

And in order to find the intercept we can use any point for example (2,20) and we got:

[tex]20 =-5(2) +b[/tex]

And then [tex] b=30[/tex]

So our function 2 is given by: [tex] y =-5x +30[/tex]

On this case if we analyze both slopes, we see that function 2 has a greater rate of change because have a slope greater on absolute value than the slope for Function 1 (|-5|>|4|). No matter if the sign is positive or no we are analyzing the rate of change and for this case we need to use the absolute value to find the solution.

You and your friend are selling magazine subscriptions. You sell 8 fewer magazine subscriptions than your friend. Together you sell 42 magazine subscriptions. Write a system of linear equations that represents this situation.

The system of linear equations that represents this situation is:

x + y = 42

x - y = 8

Step-by-step explanation:

To solve the problem assume that

∵ Your friend sells x magazine subscriptions

∵ You sell y magazine subscriptions

∵ Together you sell 42 magazine subscriptions

∴ x + y = 42 ⇒ (1)

∵ You sell 8 fewer magazine subscriptions than your friend

∵ Your friend sells x magazine subscriptions

∵ You sell y magazine subscriptions

- That means y = x - 8

∴ y = x - 8

- Add 8 for both sides

∴ 8 + y = x

- Subtract y from both sides

∴ 8 = x - y

- Switch the two sides

∴ x - y = 8 ⇒ (2)

The system of linear equations that represents this situation is:

x + y = 42

x - y = 8

Price of a hotdog = $0.86

An equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

For example, 2x – 5 = 13.

Here,

2x – 5 and 13 are expressions.

The sign that connects these two expressions is “=”.

Given,

2 burgers and 1 hotdog cost = $4.82

1 burger and 2 hotdogs cost = $ 3.70

The price is same

Let the price of burger be x and price of hotdog be y

then,

2x + y = 4.82   ---------(a)

x + 2y = 3.70  

Multiplying 2 in above equation

2x + 4y = 7. 40  -----------(b)

Subtracting equation (a) from equation (b)

2x + 4y - (2x+y) = 7.40 - 4.82

2x + 4y -2x -y = 2.58

3y = 2.58

y = 2.58/3

y = 0.86

Price of hotdog = $0.86

Hence, a hotdog costs $0.86.
