Answer: Hello there!

initially, the carpet was 8ft wide and 12ft long.

The rescaled carpet has 2ft wide.

The scale factor then is: 8ft*k = 2ft

k = 2ft/8ft = 1/4

now that we know the scale factor, we can find the length of the long side in the rescaled carpet:

x = 12ft*(1/4) = 3ft

Then, the rescaled carpet is 2ft wide and 3ft long.

The area of the square is equal to the product between the wide length and the length of the long side; so:

A = 2ft*3ft = 6ft^2

Answer:

\text{Area of reduced carpet}=6\text{ ft}^2

Step-by-step explanation:

We have been given that a piece of carpet is 8 feet wide and 12 feet long. The carpet needs to be reduced by a scale factor so that the reduced carpet is 2 feet wide.

First of all, let us find the scale factor by which the width of carpet has been reduced.

\text{Original width of carpet}\times \text{Scale factor}=2\text{ ft}

\text{8 ft}\times \text{Scale factor}=2\text{ ft}

Dividing both sides by 8 ft we will get,

\frac{\text{8 ft}\times \text{Scale factor}}{\text{8 ft}}=\frac{2\text{ ft}}{\text{8 ft}}

\text{Scale factor}=\frac{1}{4}

Let us find the length of carpet after reduced by a scale factor of \frac{1}{4}.

\text{Length of the carpet after reducing a factor of }\frac{1}{4}=12\text{ ft}\times \frac{1}{4}

\text{Length of the carpet after reducing a factor of }\frac{1}{4}=3\text{ ft}

Now we will multiply the reduced length and width of carpet to find the area of reduced carpet.

\text{Area of reduced carpet}=2\text{ ft}\times 3\text{ ft}

\text{Area of reduced carpet}=6\text{ ft}^2

Therefore, the area of reduced carpet is 6 square feet.

What other information do you need in order to prove the triangles congruent using the SAS Congruence Postulate?
Mazyrski [523]

Answer:

<CBA = <CDA

Step-by-step explanation:

Using <CBA = <CDA and Base angle theorem, you can say that AB = AD.

Now you have <CBA = <CDA, AB = AD, and CB = CD. These prove SAS.

a used truck for $4,500 he made an agreement with the dealer to put $1,500 and make payments of 350 for the next 10 months that
Aneli [31]
Ist amount paid = $1500
Making $350 for 10 months = 10*350 = $3500
Total amount paid  = 1500 + 3500 = 5000
So an amount of $5000 was paid to cover the cost of $4500 within the ten month period.
I = PRT
Interest, I = 5000 - 4500 = 500Time, t = 10 months = 10/12 = (5/6) year.Principal P = 4500
R = I /(PT)  R = 500 / (4500*5/6)
R = (500*6) / (4500*5)
R = 0.1333..
R ≈ 13.33 %  per annum.

A certain book had an original rating of 27 out of 30 points on a survey chart. Each month, the rating fell by 3 points. Express
Natali [406]

Answer:

D.) f(m)=27−3m

Step-by-step explanation:

Given that:

Original rating = 27

Total possible rating points = 30

Drop in rating point per month = 3

m = number of months since release :

Hence,

F(m) = original rating - drop in rating per month * number of months since release

F(m) = 27 - 3(m)

F(m) = 27 - 3m
