Answer:

40

Step-by-step explanation:

The formula for the perimeter of a rectangle is  P = 2l + 2w.  Since the length is 8 times the width, l = 8w.  You can plug this into the equation.

<em>P = 2(8w) + 2w</em>

<em>P = 16w + 2w</em>

P = 18w

Now, plug in the given value for perimeter, and solve for w.

<em>90 = 18w</em>

<em>(90)/18 = (18w)/18</em>

5 = w

Since the width is equal to 5, you can now solve for l.

<em>l = 8w</em>

<em>l = 8(5)</em>

l = 40

The length of the diagonal is equal to 40.

17_2_3_8=3 insert + - × or ÷ symbols to make each statement true​
erastova [34]

Answer:

17-2*3-8=3

Step-by-step explanation:

We have given:

17_2_3_8=3 insert + - × or ÷ symbols to make each statement true​?

<u>Solution:</u>

We will insert multiplication sign between 2 and 3 and then subtract all the terms

<u>17-2*3-8=3</u>

We will solve it according to the DMAS rule:

DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction. Without DMAS rule all mathematical equations will come up with different answers.

Lets solve the expression and check whether the L.H.S = R.H.S

17-2*3-8=3

17-6-8=3

11-8=3

3 =3

<em>Be sure to multiply first and then subtract</em>

⇒You can also insert addition sign in place of multiplication. It will give the same answer

What is the lcm of 4 and 5
timama [110]

Answer:

20

Step-by-step explanation:

4 * 1 = 4        5 * 1 = 5

4 * 2 = 8        5 * 2 = 10

4* 3 = 12        5 * 3 = 15

4 * 4 = 16       5 * 4 = 20

4 * 5 = 20


they both go into 20 equally. there is no number lower than 20 that they both go into

#12 with explanation please

Answer:

  • 30.01 units

Step-by-step explanation:

<u>Given vertices WXYZ:</u>

  • W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)

Perimeter is the sum of the side length.

<u>Use distance formula to find each side:</u>

  • WX = \sqrt{(2+4)^2+(4-5)^2} =\sqrt{37} ≈ 6.08
  • XY = \sqrt{(3-2)^2+(-4-4)^2} =\sqrt{65} ≈ 8.06
  • YZ = \sqrt{(-1-3)^2+(-6+4)^2} =\sqrt{20} ≈ 4.47
  • WZ = \sqrt{(-1+4)^2+(-6-5)^2} =\sqrt{130}\sqrt{(-1+4)^2+(-6-5)^2}=\sqrt{130} ≈ 11.40

<u>Find perimeter:</u>

  • P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
