louis wants to carpet the rectangular floor of his basement. The basement has an area of 864 square feet. The width of the basement is 2/3 its length. What is the length of Louis' s basement?

Answers

Answer 1
Answer: x-\ length\n\n(2)/(3)x-\ width\n\nArea=\ length*width\n\n864=x*(2)/(3)x\n\n864=(2)/(3)x^2\ \ \ | divide\ by\ (2)/(3)\n\n864*(3)/(2)=x^2\n\n432*3=x^2\n\n1296=x^2\ \ \ | \sqrt{}\n\nx=36ft\n\nLength\ is \ equal\ to\ 36ft.
Answer 2
Answer:

By definition, the area of a rectangle is given by:

Where,

w: width of the rectangle

l: length of the rectangle

Substituting values in the given equation we have:

From here, we clear the value of l.

We have then:

Answer:

the length of Louis' s basement is:

l = 36 feet

I. The range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.

II. The distribution of data is approximately symmetrical in both sets of data.

III. The mode of the number of miles Amanda skated in July is equal to the mode of the number of miles skated in August.




Answer explanation:


i only need number 4 the others ive done already PLS HURRY IM IN A RUSH ILL GIVE BRAINLYIST

Answers

Answer:

The statements i) and iii) are best supported by the dot plot.

i) The range of the number of miles Amanda skated in

   August is less than the range of the number of miles she

skated in July.

iii) The mode of the number of miles Amanda skated in July

   is equal to the mode of the number of miles skated in

   August.

Step-by-step explanation:

i) The range of the number of miles Amanda skated in August is 1 to 3

  The range of the number of miles Amanda skated in July is 1 to 4

The range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.

This is a true statement and this is the correct answer

ii)The distribution of data for the month of July is almost symmetrical but the

   data in August is not.

The range of the number of miles Amanda skated in August is less than the range of the number of miles she skated in July.

This statement is not true.

iii)The mode of the number of miles Amanda skated in July is 1.

   The mode of the number of miles Amanda skated in August is 1.

The mode of the number of miles Amanda skated in July is equal to the mode of the number of miles skated in August.

This is also a true statement.

Solve for J
J/2 + 7 = 12

Answers

Answer:

J=10

Step-by-step explanation:

J/2 + 7 = 12

Subtract 7 from each side

J/2 + 7-7 = 12-7

J/2 = 5

Multiply each side by 2

J/2 *2 = 5*2

J =10

How do you minus fractions

Answers

Hello,


in order to minus fractions, you may decrease the numerator or increase the denominator or both.
Hi there! Let's say I had to subtract 6/10 from 5/10. We would subtract 6 from 5 which is 1 and we leave the denominator the same which is 10. Therefore, we have a fraction of 1/10.

Can someone explain how to do these problem and the formula

Answers

For the first one, you would have to subtract 5 from 8 which would give you x=3!! that is your answer. For the second one, you would have to subtract 3 from -6 which would give you -a=-9, but were not done here yet, we are going to multiply this by -1 because you can't have a negative variable which will give you a=9. And last but not least, on the third one, you would have to subtract 21 from 30 which will give you c=9. There is no specific formula to do these problems other than to get rid of the "third wheel number".

17-2c for c = 7 what is the answer

Answers

Simply substitute the 7 in for c in the equation then solve...

17 - 2c =
17 - 2 (7) =
17 - 14 = 3

17-2c for c=7

Replace c by its number

17-2(7)

17-14

= 3

Yes a trapezoid is a polygon but false because a polygamy is a shape that has 3 or more sides so it could be from a triangle onwards
