A student bought a juice pouch for $2.50 and three bags of chips the total cost was $5.05 right and solve an equation to determine the cost of a bag of chips, c

Answers

Answer 1

The total amount of the purchase was ...

... $2.50 + 3c = $5.05

This equation can be solved by subtracting 2.50 and dividing by 3. Both these operations are done to both sides of the equation in accordance with the rules of equality.

... 3c = $2.55

... c = $0.85

The cost of a bag of chips was $0.85.

Answer 2
Final answer:

The cost of a bag of chips can be found by subtracting the juice price from the total cost and then dividing by the number of chip bags. This gives us an answer of $0.85 per bag.

Explanation:

To solve this problem, we need to subtract the cost of the juice from the total cost, then divide that answer by the total number of chip bags bought to find the cost of one bag. First, we subtract the juice price ($2.50) from the total spent ($5.05), which gives us $2.55. This is the total cost of the chips. Then, we divide that $2.55 by the number of chip bags bought (which is three) to find the cost of one bag. This can be represented by the equation: c = (total cost - juice price) / number of chip bags, or c = ($5.05 - $2.50) / 3. Calculating this, we find that c equals $0.85, so a bag of chips costs $0.85.

Therefore the side length is 12in.

Therefore the answer 12 in.

The total height of the stair is equivalent to 36 inches.

What is Pythagoras theorem?

Pythagoras theorem states that the square of the hypotenuse is equivalent to the square of the base and perpendicular.

We can write the formula for Pythagoras theorem as -

(hypotenuse)² = (base)² + (perpendicular)²

We can write the height of the stairs as -

h = 3 x √(15² - 9²)

h = 3 x √(225 - 81)

h = 3 x √144

h = 3 x 12

h = 36 inches

Therefore, the total height of the stair is equivalent to 36 inches.

How many Mondays would there be in 171 school days?

Answers

There are 5 days to a school week: Monday, Tuesday, Wednesday, Thursday and Friday.

Divide number of school days by 5 to find the number of weeks:

171 / 5 = 34.2 weeks.

The weeks start with Monday, so there would be 35 Mondays. ( 34 full weeks and the partial week would begin with a Monday)

Divide 171 by 7 (as there are 7 days in each week), obtaining 24.4.  There's one Monday in every 7 days, so in 168 days there'd be exactly 24 Mondays, and in 171 days there'd still be exactly 24 Mondays, with 3 days left over.

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. y= 1/3 x− 2/3

Given the graph of a line y=−x.Write an equation of a line which is perpendicular and goes through the point (8,2).

Answers

Answer:

1. (0, -2/3), (2, 0)

2. y = x-6

Step-by-step explanation:

1. Since the equation is in slope-intercept form, you know the y-intercept is -2/3. The x-coordinate there is 0, so the ordered pair is (0, -2/3).

Substituting y=0 into the equation gives the value of the x-intercept.

... 0 = 1/3x -2/3

... 0 = x - 2 . . . . . multiply by 3

... 2 = x . . . . . . . . add 2

The x-intercept is (2, 0).

2. The given line has slope -1, so the perpendicular line has a slope that is the negative reciprocal of that: -1/-1 = 1. Then the point-slope equation of the line can be written ...

... y = 1(x -8) +2

... y = x - 6 . . . . simplify

(1)

to find the intercepts

• let x = 0, in the equation for y-intercept

• let y = 0, in the equation for x-intercept

x = 0 : y = - [tex]\frac{2}{3}[/tex] → (0, - [tex]\frac{2}{3}[/tex]) ← y-intercept

y = 0 : [tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{3}[/tex] = 0 ( multiply by 3 )

x - 2 = 0 → x = 2 → (2, 0 ) ← x- intercept

(2)

the equation of a line in slope-intercept form is

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

y = - x is in this form with slope m = - 1

the slope of a perpendicular line = - [tex]\frac{1}{m}[/tex] = 1

the partial equation of the perpendicular line is

y = x + c

to find c substitute (8, 2 ) into the partial equation

2 = 8 + c → c = 2 - 8 = - 6

y = x - 6 ← equation of perpendicular line

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival. She only spent her money on ride tickets and admission into the festival. The price of admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation to calculate the cost for anyone who only pays for festival admission and rides
(c) Explain your answer to Part B.

Answers

Part (a)

The variable y is the dependent variable and the variable x is the independent variable.

Part (b)

The cost of one ticket is $0.75. Therefore, the cost of 18 tickets will be:

[tex]0.75\times 18=13.5[/tex] dollars

Now, we know that Kendall spent her money only on ride tickets and fair admission and that she spent a total of $33.50.

Therefore, the price of the fair admission is: $33.50-$13.50=$20

If we use y to represent the total cost and x to represent the number of ride tickets, the linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission can be  written as:

[tex]y=0.75x+20[/tex]......Equation 1

Part (c)

The above equation is logical because, in general, the total cost of the rides will depend upon the number of ride tickets bought and that will be 0.75x. Now, even if one does not take any rides, that is when x=0, they still will have to pay for the fair admission, and thus their total cost, y=$20.

Likewise, any "additional" cost will depend upon the number of ride tickets bought as already suggested. Thus, the total cost will be the sum of the total ride ticket cost and the fixed fair admission cost. Thus, the above Equation 1 is the correct representative linear equation of the question given.

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 22.5 - 16.5 = 6




Final answer:

The interquartile range (IQR) for the given data set is calculated by first arranging the data in ascending order, finding the first and third quartiles (Q1 and Q3), and subtracting Q1 from Q3. The correct IQR for this data set, following this methodology, is 6, not the mistakenly provided 7.

Explanation:

The question asks about calculating the interquartile range (IQR) of a given data set. The IQR is important because it measures the middle 50% spread of data, pinpointing where the bulk of values lie, and helps in identifying potential outliers. To compute the IQR, we first need to organize the data in ascending order, then find the first quartile (Q1) and the third quartile (Q3), and finally subtract Q1 from Q3 (IQR = Q3 - Q1).

For the provided data set: 17, 16, 21, 15, 25, 22, 18, 23, 17:

Arrange data in ascending order: 15, 16, 17, 17, 18, 21, 22, 23, 25.

Find the median (Q2), which is 18 in this case as it's the middle value.

Q1 is the median of the first half (excluding the middle value if odd number of data), so Q1 = 16.5.

Q3 is the median of the second half, hence Q3 = 22.5.

Therefore, IQR = Q3 - Q1 = 22.5 - 16.5 = 6.

Contrary to the mistaken calculation of IQR as 9 - 2 = 7 provided in the reference, the computed IQR for this data set, following the correct methodology, is 6.

Mrs.Palmer bought one pair of goggles, one bathing suit, and one beach towel for each of her three daughters.Suppose she had $18 left after buying the swimming items.Write an equation to determine the amount Mrs.Palmer originally had to spend on each daughter.

Answers

To find the amount Mrs. Palmer originally had to spend on each daughter, we set up the equation as (x - 18) / 3 = y, where x is the total money she initially had and y indicates the amount spent on each daughter.

Let's denote the total amount Mrs. Palmer originally had as x.

We know she spent this on buying swimming items for her three daughters and had $18 left afterwards.

This infers that the total money she spent is (x - 18) dollars.

Since each daughter received a pair of goggles, a bathing suit, and a beach towel, this means she used this money to buy three sets of swimming items.

Therefore, the amount of money she spent on each daughter is equal to (x - 18)/3.

The equation to find out what x (the amount Mrs. Palmer originally had) is therefore:

(x - 18) / 3 = y

where y represents the amount she spends on each daughter.

Find the measures of the angles of a triangle whose angles have a measure of x, 1/2x, and 1/6x. Also, what kind of triangle is it?

Answers

the sum of the angles in a triangle = 180°, thus

x + [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{6}[/tex] x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle


Final answer:

The measures of the angles of the triangle are approximately 108 degrees, 54 degrees, and 18 degrees. This type of triangle is a scalene triangle, as all of its angles are different.

Explanation:

To find the measures of the angles of a triangle whose angles are x, 1/2x, and 1/6x, we will use the fact that the sum of the angles in a triangle is always 180 degrees. The equation representing this is:

x + 1/2x + 1/6x = 180

Combine like terms:

1.6667x = 180

Then solve for x:

x ≈ 108 degrees

Now plug x into the original angle measures to get:

Angle 1 = 108 degrees

Angle 2 = 1/2x = 54 degrees

Angle 3 = 1/6x = 18 degrees

Lastly, in terms of the type of triangle, this is a scalene triangle because all of its angles are different.

1 km = 1,000 m in Chicago is represented by 10 cm on the map.

The statement C expresses the same scale.

 

D. 100 cm in Chicago is represented by 1 m on the map?

100 cm = 1 m

Rule of three:

1 cm    represents 100 m

x         represents  1 m

x=(1 cm).(1 m) / (100 m)

x=0.01 cm

100 cm = 1 m in Chicago is represented by 0.01 cm on the map.

The statement D doesn't express the same scale.

Compute the following volume and surface area. A rectangular pyramid has a base measuring 4 in. on each side and an altitude of 6 in. What is its volume? cubic inches

Answers

692 square centimeters

32 inches³

the volume V of a pyramid = [tex]\frac{1}{3}[/tex] × area of base × height

area of base = 4² = 16 and h = 6

V = [tex]\frac{1}{3}[/tex] × 16 × 6 = 32


Mr. Spencer has 7 1/5 L of juice. Do you wanna support equal amounts of juice into three punch bowls. How many liters of juice should he poured to each bowl

Answers

Into each bowl, he will pour

... (1/3)×(7 1/5) = (1/3)×(6 6/5) = 2 2/5 . . . liters of juice

_____

Here, we have elected to rewrite 7 1/5 as 6 6/5 so each part of the number (whole number, fraction) will be divisible by 3.

You may have been taught to convert 7 1/5 to an improper fraction before doing the multiplication. That method looks like ...

... (1/3)×(36/5) = 12/5 = 2 2/5 . . . . same result

an angle measures 2 degrees more than 3 times it’s complement. find the measure of its complement.

Answers

If the angle is 90 degrees, then the complement would be 27, because 90 / 3 = 30, and 30 - 3 = 27. Basically, you divide the angle by 3 and subtract 3 to find the complement if this is the case.

Answer:

22⁰

Step-by-step explanation:

Angle = x

Complement = 90 - x

Given:

x = 3 (90 - x) + 2

x = 270 - 3x + 2

4x = 272

x = 68

Complement = 90 - 68 = 22⁰

N-6.47=4.32 what is the unknown number for N?

Answers

N = 10.79

isolate N by adding 6.47 to both sides of the equation

N = 4.32 + 6.47 = 10.79


The unknown number N in the equation N - 6.47 = 4.32 is found to be 10.79 when we add 6.47 to both sides of the equation.

To solve for the unknown number N in the equation N - 6.47 = 4.32, we must isolate the variable N on one side of the equation. We do this by adding 6.47 to both sides of the equation:

N - 6.47 + 6.47 = 4.32 + 6.47

This simplifies to:

N = 10.79

The unknown number N is therefore 10.79. When providing the final answer, we must make sure that it is reported with the correct number of significant figures, which in this case are three significant figures.

An amusement park offers a yearly membership of $275 that allows for free parking and admission to the park. Members can also use the water park for an additional $5 per day. Nonmembers pay $6 for parking, $15 for admission, and $9 for the waterpark.

Write and solve an equation to find the number of visits it would take for the total cost to be the same for a member and a non-member if they both use the waterpark at each visit.

Answers

$275.00+$5.00=$280.00

$6.00+$15.00+$9.00=$30.00

So, 280÷30=9.3<- the 3 being a repeating decimal can be rounded to the hundredths which would be 9.33 but rounded to the nearest whole number would be 9

The yearly membership cost plus the cost per visit was set equal to the non-member cost per visit, and solving the equation gave us the result.

We need to find the number of visits it would take for the total cost of a member and a non-member to be the same if they both use the waterpark at each visit. Let's denote the number of visits as x.

The yearly membership cost is $275, and each visit to the waterpark costs an additional $5 for a member. So, for x visits, the total cost for a member is:

Member cost = $275 + $5x

Non-members pay $6 for parking, $15 for admission to the park, and $9 for the waterpark per visit. Therefore, the total cost for a non-member is:

Non-member cost = ($6 + $15 + $9)x = $30x

Setting both costs equal to find the number of visits where the costs are the same:

$275 + $5x = $30x

Now we solve for x:

$275 = $30x - $5x

$275 = $25x

x = $275/$25

x = 11

Therefore, it would take 11 visits for the total cost to be the same for a member and a non-member if they both use the waterpark at each visit.
