The perimeter of a rectangle is 13 cm and its width is 2 ¾ cm. Find its length in cm.​

Answers

Answer 1

Answer:

length = 3 3/4

Step-by-step explanation:

13 = 2(2 3/4) + 2l

13 = 2(11/4) + 2l

13 = 22/4 + 2l

52/4 - 22/4 = 2l

30/4 = 2l

30/4 ÷ 2 = l

30/4 x 1/2 = l

30/8 = l

length = 15/4 or 3 3/4

Does anybody know how to find the distance between 2 things using the pythagorean theorem?​

Answers

Answer:

Yes

Step-by-step explanation:

The two objects are plotted at different points in graph and one gets the difference of points y coordinates (change in y) and change in x too.

Then one can look for distance as hypotenous and change in y as height and change in x as the base of our imaginery triangle.

Therefore, from Pythagoras Theoreom:

hyptenous² = height² + base²

Distance² = change in y² + change in x²

Distance = √change in y² + change in x²

Is (–3, –10) a solution to this system of inequalities? y ≥ 7x − 2 y < 4x + 7

Answers

Answer:

No, it is not a solution

Step-by-step explanation:

Given the inequality y ≥ 7x − 2 and y < 4x + 7, they can be combined and written as;

7x-2≤y<4x+7

Equate both values of y, the point of intersection occurs when;

7x-2 = 4x+ 7

7x - 4x = 7 + 2

3x = 9

x = 9/3

x = 3

Substitute x = 3 into y = 7x - 2

y = 7(3) - 2

y = 21 - 2

y = 19

Hence the possible solution will be at (3, 19). Hence the solution (-3, -10) is incorrect

there are two holes in the roof that are leaking water. the one in the bathroom drift 120 drops in an hour. the other one in the kitchen dripped 80 drops in 30 minutes. which one is leaking more water?​

Answers

Answer:

the more leaking place is the bathroom

Explanation:

1 hour=60 minutes

   the bathroom drift 120 drops in 60 minutes

so, the bathroom drift 1 drop in 120/60 minutes

                                                    =60 minutes

    the other one in the kitchen dripped 80 drops in 30 minutes.

so, the other one in the kitchen dripped 1 drop in 80/30 minutes

                                                                                   = 8/3 minutes

                                                                                 

so the more leaking place is the bathroom because 60 > 8/3

A wire is first bent into the shape of a rectangle with width 7in and length 9in then the wire is bent and reshaped into a square what is the length of a side of a square.

Answers

Answer:

Length of side of square = 8 inch

Step-by-step explanation:

Given:

Length of rectangular wire = 9 inch

Width of rectangular wire = 7 inch

Find:

Length of side of square

Computation:

We know that same wire is used from square

So,

Perimeter of rectangle = Perimeter of square

2[l + b] = 4 x side

2[9 + 7] = 4 x Length of side of square

2[16] = 4 x Length of side of square

32 = 4 x Length of side of square

Length of side of square = 32 / 4

Length of side of square = 8 inch

Answer:

7x-2=19

5x=15

5x+6=21

................

Step-by-step explanation:

Here x = 3

3x = 1 (False)

3* 3 ≠1

3x = 33 (False)

3 *3 ≠ 33

7x - 2 =19 (True)

7 *3 - 2 = 19

21 - 2 = 19

19 = 19

2x = 5 (False)

2 *3 ≠ 5

5x = 15 (True)

5 * 3 = 15

15 = 15

5x + 6 = 21 (True)

5 * 3 + 6 = 21

15 + 6 = 21

21 = 21

Eliminate the y in the following system of equations. What is the result when you add the two equations?
3x - 2y = 8
x + y = 6

Answers

Answer:

X=4

Step-by-step explanation:

3x-2y=8

x+y=6

multiply second equation by 2 so you can eliminate y

2(x+y)=2(6)

2x+2y=12

now add two equations together

first equation:                          3x-2y=8

modified second equation     2x+2y=12

added together eliminates y. 5x+0=20
