her purchase, before sales tax. Sales tax is 6%. How much did Emily pay for the clothes after the
coupon and sales tax?

Answers

Answer 1

Answer: $57.77

Step-by-step explanation:

3 x 12.50 = 37.5 + 20 = 57.5

57.5- 3 = 54.5

54.5 x .06 = 3.27

A dog pen is 18
feet wide. Its length
is twice the width.
What is the total
perimeter of the
pen?

Answers

Answer:

108 ft

Step-by-step explanation:

18x2=36

36+36+18+18=108

Perimeter is the total added amount that surrounds the shape.

Final answer:

The length of the dog pen is twice the width, hence 36 feet. Using the formula for perimeter of a rectangle, the total perimeter of the pen is 108 feet.

Explanation:

To calculate the perimeter of a rectangle, we use the formula 2(length + width). Given the width of the dog pen is 18 feet, and the length is twice the width, we first calculate the length: 2 * 18 feet = 36 feet. With that, we can now calculate the perimeter: 2(18 feet + 36 feet) = 2 * 54 feet = 108 feet. Therefore, the total perimeter of the dog pen is 108 feet.

9) In one year, Angie's height went from 58 to 60 inches. What was the percentage increase in Angie's height? (Round to the nearest percentage)

Answers

The percentage increase in Angie's height is 3 %

Solution:

Given that, In one year, Angie's height went from 58 to 60 inches

To find: percentage increase

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

[tex]\text { percent increase }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100[/tex]

Here in this problem,

Initial value = 58 inches

Final value = 60 inches

Substituting the values we get,

[tex]percent\ Increase = \frac{60-58}{58} \times 100\\\\percent\ Increase = \frac{2}{58} \times 100\\\\percent\ Increase = 0.0344 \times 100\\\\percent\ Increase = 3.45 \approx 3[/tex]

Thus percentage increase in Angie's height is 3 %

On a coordinate plane, a straight line with a negative slope, labeled f of x, crosses the y-axis at (0, 4), and the x-axis at (4, 0). Which is true regarding the graphed function f(x)?

Answers

Final answer:

The graph of function f(x) that crosses the y-axis at (0, 4) and the x-axis at (4, 0) is a straight line with a negative slope, making option a correct.

Explanation:

Considering the information given, the graph of the function f(x) intersects the y-axis at (0, 4) and the x-axis at (4, 0). By determining the slope of the line, which is the change in y divided by the change in x (rac{ ext{rise}}{ ext{run}}), we can conclude that the slope is negative because the line goes down as it goes right.

The slope is  rac{0 - 4}{4 - 0} = -1.

Therefore, option a, stating it is a straight line with a negative slope, correctly describes the graph of function f(x).

Make sure you know the Order of Operations, or PEMDAS.

PEMDAS:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

When simplifying, you need to do it in this order. However, with multiplication and division, you do it whichever comes first. If it's 24 times 3 divided by 4, you do multiplication first because it came first in the problem. Then you divide by 4.

The same thing with addition and subtraction. For example, 2 + 4 + 8 - 11, you need to add 2+4+8 first because addition came first before subtraction.

If you don't understand feel free to reply with questions about it.

ALSO: If numbers are written together like (-2)(3), this means they are being multiplied.

Okay so let's solve this equation now.

Looking at PEMDAS, the first step would be to multiply or divide. Seeing that division comes first, do 24 divided by -2.

24 ÷ -2 = -12 (Remember that positive divided by a negative or the other way around will always result in a negative. Same with multiplying)

Now we have: -12(3)+7

Next step is multiplication so -12*3=-36

Now we have -36 + 7.

Adding a negative is the same as subtracting a positive so you can re-write this as 7- 36. Well, 36 - 7 is 29, so 7 - 36 = -29.

So, the answer is -29


The velocity v of an object rolled down an inclined plane is given by the formula v=
53d, where d is the distance the object has rolled, Solve the formula for d.

Answers

Final answer:

To find the distance an object has rolled down an inclined plane from the velocity equation v = √(53d), square both sides of the equation and then divide by 53 to solve for d.

Explanation:

The velocity v of an object rolled down an inclined plane is given by the formula v = √(53d), where d is the distance the object has rolled. To solve this equation for d, we can square both sides of the equation to remove the square root. The steps are as follows:

Square both sides of the equation: v² = (53d)².

Divide both sides by 53 to isolate d: d = v² / 53.

Now, d represents the distance the object has rolled down the inclined plane as a function of its velocity v.

Step-by-step explanation:

125÷5 = 25

5 goes into 125 exactly 25 times. This result is obtained by dividing 125 by 5. The answer is 25.

To determine how many times the number 5 goes into 125, we need to perform division:

Set up the division problem: 125 divided by 5.Divide 125 by 5.
125 ÷ 5 = 25Therefore, 5 goes into 125 exactly 25 times.

This means if you divide 125 by 5, the result is 25, showing that 5 fits into 125 exactly 25 times.

Step-by-step explanation:

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 245 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?

Answers

Answer:

140 ounces of water and 105 ounces of 35% salt solution.

Explanation:

Let [tex]x[/tex] be the ounces of water that need to be added and [tex]y[/tex] be the ounces of 35% solution that need to to be added.

We know that the total of ounces of water and of 35% solution must be 245 ounces:

[tex]x+y=245[/tex]

35% of  [tex]x[/tex] is the salt, and since no salt is added with addition of [tex]y[/tex]  liters of water, this must be equal to the amount of salt in the final 15% solution:

[tex]0.35x=0.15*245[/tex]

we solve for  [tex]x[/tex] and get:

[tex]x=105[/tex]

We put this value into [tex]x+y=245[/tex] and solve for [tex]y[/tex] to get:

[tex]y=140[/tex]

Thus we have 140 ounces of water and 105 ounces of 35% solution.

Final answer:

To obtain a 245-ounce mixture at 15% salt concentration, the scientist needs to mix 140 ounces of water with 105 ounces of 35% salt solution by solving a system of equations that involves the total mass of the solution and the mass of the salt in the mixture.

Explanation:

The student is asking for help with a mixing solution problem in algebra where they need to combine water with a 35% salt solution to create a final mixture that has a 15% salt concentration. To solve this problem, two key equations must be set up based on the mixture's total mass and the mass of the salt within the mixture. The student wants 245 ounces of the final mixture.

Let's denote X as the number of ounces of water (0% salt) and Y as the number of ounces of the 35% salt solution. The first equation is based on the total mass of the final solution: X + Y = 245. The second equation is based on the mass of the salt in the solution: 0*X + 0.35*Y = 0.15*245.

Now, we solve the system of equations. The second equation simplifies to 0.35Y = 36.75. Dividing both sides by 0.35 gives Y = 105 ounces. Substituting Y into the first equation gives X = 140 ounces. Therefore, the scientist needs to mix 140 ounces of water with 105 ounces of the 35% salt solution to achieve the desired concentration.

A truck enters a highway driving 60 miles per hour a car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway how long will it take the car to pass the truck

Answers

The time taken by car to pass the truck is 1.125 hours

Solution:

A truck enters a highway driving 60 miles per hour a car

The car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway

Let us first convert 9 minutes to hours

[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]

[tex]9 \text{ minute } = \frac{9}{60} = \frac{3}{20} \text{ hours }[/tex]

Let the truck covers 'x' m distance in time 't' hour the car will take [t -(3/20)] hour to cover the same distance 'x'

We know that,

[tex]Distance = Speed \times Time[/tex]

For truck : [tex]x = 60t[/tex] ----------- eqn 1

For car: [tex]x = 68 \times (t - \frac{3}{20})[/tex] ------------ eqn 2

From equations (i) and (ii)

[tex]60t = 68 \times(t-\frac{3}{20})\\\\60t = 68t-10.2\\\\68t - 60t = 10.2\\\\8t = 10.2\\\\t = 1.275[/tex]

Thus the time taken by car to pass the truck is:[tex]t - \frac{3}{20} = 1.275 - \frac{3}{20} = 1.275 - 0.15 = 1.125[/tex]

Thus the time taken by car to pass the truck is 1.125 hours

Admittedly this is a lot of things to keep track of and it's easy to get lost. Hopefully the process is fairly straight forward even if it requires a lot of drawings.

The chart showing the values of n and the final winners is shown below in the attached image.

Each pattern block is color coded to separate the start and stop of each sequence. Note the pattern of {1,3} then {1,3,5} then {1,3,5,7} then {1,3,5,7,9} and so on. The next pattern block would likely be {1,3,5,7,9,11}. This table will help you determine what seat you will want to sit in if you know how many players there are at the start. Of course you won't know ahead of time how many players there are, but when it comes to you picking your seat you can quickly look at the table (either on the paper or just something you memorize) and you can select the ideal seat based on what n is.

Step-by-step explanation:

First of all, we will find the solution of the given equation

So,

Given equation is:

[tex]3m = 36-6m[/tex]

Adding 6m on both sides

[tex]3m+6m = 36-6m+6m\\9m = 36[/tex]

Dividing both sides by 9

[tex]\frac{9m}{9} = \frac{36}{9}\\m = 4[/tex]

In order to check, if the solution is the solution of given options, we will put the solution in the equation, if both sides of equations are equal then the solution belongs to the equation.

So,

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

Putting m=4

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

For [tex]-2(-4m-6.4) = 44.8[/tex]

Putting m=4

[tex]-2[-4(4)-6.4]=44.8\\-2(-16-6.4) = 44.8\\-2(-22.4) = 44.8\\44.8 = 44.8[/tex]

For [tex]8m-5-2m +1 = 20[/tex]

Putting m=4

[tex]8m-5-2m +1 = 20\\6m-4 = 20\\6(4) -4 = 20\\24-4 = 20\\20 = 20[/tex]

for [tex]7m+6 = 9m-2[/tex]

Putting m = 4

[tex]7(4) +6 = 9(4) - 2\\28+6 =36-2\\34=34[/tex]
