Nia's backpack after 30% off represents 70% of the original backpack cost. Setting up a ratio of 70/100 = 14/X, we can solve for the original price, X. Patrick will pay $20 if he does not have a 30% off coupon.

This problem can be solved using a bit of Percentage Calculations. We know that after a 30% discount, Nia's backpack cost $14. This means that $14 represents 70% of the original backpack cost (100% - 30%). So to find out the 100%, or the full price, we need to determine what number 70% is 14 of. We can set up a ratio to find the original cost (X).

The steps are:

So, the backpack would cost Patrick $20 without a 30% off coupon.

Step-by-step explanation:

Hi! I am a little confused because in this question they would normally ask for the equation of the line but if you are wondering what the slope is, it says in the information that the slope is 2. I will solve for the line equation anyway though.

A line has this form: y=mx+b.

For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.

First, we can put in the point into the equation. The point given is (14,33) so the x value is 14 and they y value is 33.

y=mx+b

33=m(14)+b

We know the slope is 2 (from the given information) so we can substitute that in for m.

33=(2)(14)+b

Solving for b, the Y-intercept, we get b=5.

Perhaps your question was "what is the Y-intercept" and then this would be the answer.

Finally, the final equation for the line is:

y=2x+5

Hope this helps!

Step-by-step explanation:

A quick way to do this sort of question:

First add the last number and the first number:

1 + 960 = 961

Then divide the total amount of numbers by 2.

960 ÷2 = 480

Now multiply these two numbers together:

961 × 480 = 461280

The sum of the whole numbers from 1 to 960 can be found using the formula for the sum of an arithmetic series. By substituting the values into the formula, we find that the sum is 461280.

The sum of the whole numbers from 1 to 960 can be found using a simple formula for the sum of an arithmetic series. The formula is S = n/2 * (a + l), where 'n' is the number of terms, 'a' is the first term, and 'l' is the last term.

In this case, 'n' is 960 (there are 960 terms from 1 to 960), 'a' is 1 (the first term), and 'l' is 960 (the last term).

Plug these values into the formula to get: S = 960/2 * (1 + 960) = 480 * 961 = 461280. So, the sum of the whole numbers from 1 to 960 is 461280.

Answer:

210 people are there at the fair

Step-by-step explanation:

Let the total number of people at the fair = X

People under 16 years old        = 70% of X = 0.7 X

People remaining                       = Total number of people - Under 16 years

                                                    = X - 0.7X = 0.3X

The number of teachers             = 1/3 of People remaining = 1/3 of 0.3X

Since there are 21 teachers

                            1/3 of 0.3X       =  21

                              1/3 x 0.3X       =  21        

                                     0.1X         =   21  

Divide both sides by the coefficient of X            

                                    0.1X/0.1     =   21/0.1

                                               X     =  210

Answer:

Option D.

Jenn's answer is not correct. She got it substituting [tex]c=4[/tex] into the equation and solving for "x".

Step-by-step explanation:

Given the following equation:

[tex]\frac{1}{2}(2x + 4) = 3x-c[/tex]

Since you need that [tex]x=4[/tex], you hace to substitute that value into the equation:

[tex]\frac{1}{2}(2(4) + 4) = 3(4)-c[/tex]

Now you need to solve for "c":

[tex]\frac{1}{2}(8 + 4) = 12-c\\\\\frac{12}{2}= 12-c\\\\6=12-c\\\\c+6=12\\\\c=12-6\\\\c=6[/tex]

Therefore for a  a value of [tex]c=6[/tex], you get [tex]x=4[/tex]

Then, the you can identify that the correct answer is the one given in the Option D.

Jenn made a mistake, because she substituted [tex]c=4[/tex] into the equation and then solve for "x":

[tex]\frac{1}{2}(2x + 4) = 3x-(4)\\\\x+2=3x-4\\\\2+4=3x-x\\\\6=2x\\\\\frac{6}{2}=x\\\\x=3[/tex]

To determine the value of c when x equals 4 in the given equation, substitute x with 4 and solve for c. The resulting value of c is approximately 11.9167.

To find the value of c for which x = 4 in the equation 1 / (2x + 4) = 3x - c, we start by substituting x with 4:

1 / (2×4 + 4) = 3×4 - c
1 / (8 + 4) = 12 - c
1 / 12 = 12 - c

Now we solve for c:

1 / 12 = 12 - c
c = 12 - 1 / 12
c = 12 - 0.0833

Finally, we find the value of c:

c = 11.9167

Therefore, for x = 4, the value of c is approximately 11.9167.

y = 2x + 1 is the equation of a line that passes through (1,3) and (4,9)

Solution:

Given that we have to write the equation of a line that passes through (1,3) and (4,9)

Let us first find the slope of line

The slope of line is given as:

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

Here the given points are (1,3) and (4,9)

[tex](x_1, y_1) = (1, 3)\\\\(x_2, y_2) = (4, 9)[/tex]

Substituting the values in formula, we get,

[tex]m = \frac{9-3}{4-1}\\\\m = \frac{6}{3} = 2[/tex]

Thus slope of line is 2

The equation of line in slope intercept form is given as:

y = mx + c -------- eqn 1

Where, "m" is the slope and "c" is the y - intercept

To find the y intercept, substitute (x, y) = (1, 3) and m = 2 in eqn 1

3 = 2(1) + c

c = 1

Thus the equation of line is:

Substitute c = 1 and m = 2 in eqn 1

y = 2x + 1

Thus equation of line is found

The height of lighthouse is 52.2 yards

Solution:

Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the  ground and the top of the lighthouse is 41 degree

The diagram is attached below

Consider a right angled triangle ABC

AB is the height of the lighthouse

BC is the distance between the base of a lighthouse and Photographer

As per given, BC = 60 yards

Angle between the ground and the top of the lighthouse is 41 degree

Step-by-step explanation:

Both forms are equivalent, just different ways to write the same thing

==============================================

Explanation:

Use the slope formula first

The points we plug in are (x1,y1) = (-3,4) and (x2,y2) = (6,1)

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

m = (1-4)/(6-(-3))

m = (1-4)/(6+3)

m = (-3)/(9)

m = -1/3

The slope of the line is -1/3

Use one of the points, say the point (x,y) = (-3,4) and the slope we just found with y = mx+b. The goal is to solve for b

y = mx+b

4 = (-1/3)*(-3) + b

4 = 1 + b

4-1 = b

3 = b

b = 3

We have m = -1/3 as the slope and b = 3 as the y intercept

Therefore, the equation in slope intercept form is y = (-1/3)x + 3

In standard form, Ax+By = C, this is is equivalent to x+3y = 9 after we multiply both sides by 3, then add x to both sides.

Step-by-step explanation:

The currently rented double-occupancy apartments are 38 apartments.

Step-by-step explanation:

An apartment has rented x apartments with two occupants and 16 apartments with one occupant and the total occupants were 92, these can be written in the equation as

[tex]2x+16=92[/tex]

To find the number of double occupancy apartments that are rented, we need to solve the equation and find the value of x.

[tex]2x+16=92[/tex]

Subtracting 16 from both sides of the equation,

[tex]\begin{aligned}&2 x=92-16\\&2 x=76\end{aligned}[/tex]

Dividing both sides by 2, we get,

[tex]\begin{aligned}\frac{2 x}{2} &=\frac{76}{2} \\x &=38\end{aligned}[/tex]

Thus, there are 38 double-occupancy apartments are currently rented.

The correct answer is that there are 38 double-occupancy apartments currently rented.

To solve the problem, we start with the given equation that represents the total number of occupants in the apartment building:

[tex]\[ 2x + 16 = 92 \][/tex]

This equation takes into account that each double-occupancy apartment (x) houses two occupants, and there are also 16 single-occupancy apartments. We want to find the value of x, which represents the number of double-occupancy apartments.

First, we subtract 16 from both sides of the equation to isolate the term with x:

[tex]\[ 2x + 16 - 16 = 92 - 16 \][/tex]

[tex]\[ 2x = 76 \][/tex]

Next, we divide both sides of the equation by 2 to solve for x:

[tex]\[ \frac{2x}{2} = \frac{76}{2} \][/tex]

[tex]\[ x = 38 \][/tex]

Therefore, there are 38 double-occupancy apartments currently rented in the building. This matches the correct answer provided at the beginning.
