Answer:

17.60

Step-by-step explanation:

Look at the room carefully, the length of the room is 11 feet

And the height = 10 feet

The area of the 4 walls of the room = 4( 11×10) = 440 sq ft

Area covered by each roll = 25 sq ft

= 440/25 = 17.60 rolls

Therefore we require 17.60 rolls to cover a rectangular room on all four sides.

Alisiya [41]

Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Step-by-step explanation:

Since we have given that

Number of yards of red fabric purchased by Jane = 50

Number of yards of gold fabric purchased by Jane = 110

We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.

For this we will find H.C.F. of 50 and 110.

Factors of 50 = 1, 2, 5, 10, 25, 50.

Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.

So, Highest common factor of 50 and 110 is 10.

So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

Number of yards of red fabric is given by

\frac{50}{10}=5

Number of yards of gold fabric is given by

\frac{110}{10}=11

Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Natali [406]
Hey!!

here is your answer >>>

As we know, The formula for the length of a trinagle is

(1/2)(base)(height) !.

Height is 6/5 and area is 2/5, then what is the base, we will just have to substitute these values!.

which is ,

2/5 = (1/2)(base)(6/5)

2/5 = (base)(3/5)

base = (2/5)/(3/5)

base = (2/5)(5/3)

base = 2/3 ft!.

Hope my answer helps!

Best Method using system of equations<br><br><br> x=4y+8<br> 2x-8y=-3
Mkey [24]
In this case, since one equation is in the form of x=, substitution would be best for this problem.  Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.
