If carpet costs $12 per square yard. How much will it cost to carpet a room that is 180 square feet?

Answers

Answer 1
Answer: 12$ per 3×3 if its square yard

so 180 ÷ 9 = 20

20×12$=240$
Answer 2
Answer:

Answer:

12$ per 3×3

180 ÷ 9 = 20

20×$12=$240

Answer:

The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft

Step-by-step explanation:

Given;

two side of the triangle, 6 ft and 6 ft

let the third side of the triangle = x

Apply the rules of length of a triangle to determine the third side of the triangle.

Based on this rule:  (6 - 6)  < x < (6 + 6)

                                    0 < x < 12 ft

Therefore, the length of the third side will be greater than 0 but less than 12 ft

The possible length of the third side = 1 ft, 2 ft, 3 ft, 4 ft, 5 ft, 6 ft, 7 ft, 8 ft, 9 ft, 10 ft or 11 ft

Help!!! Geometric series.

Answers

Not just any geometric series, but an infinite one. The rare taming of infinity.

Since the ratio r=2/5 is strictly between -1 and 1 the infinite geometric series converges. The first term is also a=2/5 so the sum is

S = (a)/(1-r) = (2/5)/(1 - 2/5) = \frac 2 3

Answer: 2/3

That formula isn't too hard to derive. We have

S = a + ar + ar^2 + ar^3 + ...

rS = ar +  ar^2 + ar^3 + ...

S-rS = a

S = (a)/(1-r)

Thuy drives 270 miles in 6 hours. How many miles does Thuy drive in 13 hours? 455 miles 585 miles 624 miles 715 miles

Answers

One way you can solve this is with proportions/ratios with multiplication
(270miles)/(6hours) = (X miles)/(13hours)

Cross Multiply
(270 miles)(13 hours)=(X miles)(6 hours)
3510=6X
(3510)/(6) = (6X)/(6)
585 miles=X

The answer is 585 miles
he drives 270 miles in 6 hours and 6x2= 12 so we are going to divide 270 in 6.
270%6= 45.
Now we multiply: 270x2=540
and we add 45 that equals an hour of driving.
540+45= 585
Now we got 13 hours of driving
Thuy drives 585 miles in 13 hours.
