Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth. He also needs an extra 0.875 feet of fabric to make a matching potholder. The length of the table cloth is 4/3 of its width (w) in feet. The total amount of fabric needed (f), in feet, is represented by the equation below. f=2 (w+4/3 w) + 0.875 Quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder. What is the width of Quinn's tablecloth?

Wendy earns $2 for every table she serves plus 20% the total customer order. Define a variable and write an expression to represent the amount of money she earns for one table

Answers

The question asks you to write an algebraic expression to represent the amount of money she earns for one table:

$2(1) + 0.20(c) = m

Explanation:

She earns $2 per table and she's serving one table, so it would be $2(1)
and then she also earns 20% of the total customer order, so it would be
+ 0.20(c), c stands for the customer order

and m would represent the amount of money she earned

At a music store, the price of a set of speakers is $245, plus the sales tax of 6.5%. What is the total cost of the speakers, including the sales tax?

Answers

In order to find out what the additional value of the sales tax would be,which is 6.5%, you have to find 1% of $245. Which is $2.45. As you're looking for 6.5%, you have to multiply $2.45 by 6.5, which gives you $15.93 (rounded). In order to find the cost including the sales tax, you have to add $15.93 to the original price of $245, which gives you $260.93.Therefore, the price of the speakers, including a sales tax of 6.5% is $260.93Hope this helps :)
So,

The total cost = cost + sales tax

cost + sales tax = x or total cost

1. cost = $245

2. sales tax = 0.065(cost)

245 + 0.065(cost) = x

Simplify
245 + 15.925 = x

Round to the nearest hundredth
245 + 15.93 = x

Collect Like Terms

260.93 = x

The total cost of the speakers, including tax, is $260.93.

Elia rode her bicycle from her house to the beach at a constant speed of 18 kilometers per hour, and then rode from the beach to the park at a constant speed of 15 kilometers per hour. The total duration of the rides was 1 hour and the distance she rode in each direction are equal. Let b be the number of hours it took Elia to ride from her house to the beach, and put p the number of hours it took her to ride from the beach to the park.

Answers

Answer:

\displaystyle b=0.45\ h

\displaystyle p=0.55\ h

Step-by-step explanation:

Cinematics

When an object moves at a constant speed, it can be computed as

\displaystyle v=(x)/(t)

Where x is the distance traveled and t the time needed to complete it at the constant speed v

If we wanted to compute t from the equation above, then

\displaystyle t=(x)/(v)

Elia rode her bicycle from her house to the beach at 18 km/h and then from the beach to the park at 15 km/h, taking 1 hour in the whole travel, each distance being equal. If we call b as the number of hours it took Elia to ride from her house to the beach, and p the number of hours it took her to ride from the beach to the park, then we can compute

\displaystyle b=(x)/(18)

\displaystyle p=(x)/(15)

The question doesn't ask for something in particular, so I'm helping you by solving the complete problem. We know the total time is 1 hour, so

\displaystyle b+p=1

Replacing b and p

\displaystyle (x)/(18)+(x)/(15)=1

Multiplying by 90

\displaystyle (90x)/(18)+(90x)/(15)=90

Simplifying and solving for x

\displaystyle 5x+6x=90

\displaystyle 11x=90

\displaystyle x=(90)/(11)=8.18\ km

We finally compute b and p

\displaystyle b=(8.18)/(18)=0.45\ h

\displaystyle p=(8.18)/(15)=0.55\ h

What is the measure of the radius of S?

Answers


A diameter is a straight line that crosses a circle and the radius equals the half of this distance. So, in our case, the diameter would be YL which equals 12.2 adn the radius would be:

12.2 / 2 = 6.1


Though you could see it this way, there is still another way of finding the radius. The radius is a straght line that goes from the centre to any point of the circle, which is the same thing as saying that it is half of a diameter:

SG is a line going from the centre (S) to G, which is also equal to 6.1


Hope it helped,

If the question is asking the radius of 'the circle' S, then we need to pick a point on the circle and measure its distance from the center.

In this case, we already have G picked for us and S is the center. So, GS is our radius. It is also written that GS is equal to 6.1. This means the length of the radius of the circle S is 6.1.


Another way of finding it is; as you can see from the picture, YL is a line which goes through the point S or the center. We call those lines a 'diameter'. Diameters also equal to two times of the radius.

So, we know that our diameter is 12.2, when we divide that by 2 we got: (12.2)/(2) = 6.1 as our radius.
