The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions

Answers

Answer:

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

75% of 48 show all the work

Answers

Answer:

36

Step-by-step explanation:

75%=0.75

0.75*48=3/4*48=144/4=36

Answer:

75% of 48 is 36.

Step-by-step explanation:

So, what I did here was to first find out what 25% of 48 is, because 75% is 25% multiplied by 3.

50% of 48 = 24

Since 25% is half of 50% all we have to do is divide by 2.

24 ÷ 2 = 12.

Now, we multiply by 3.

12 * 3 = 36

So, the answer is 36.

Hope this helps! :)

convert 10009 out of 17%​

Answers

Answer:

Step-by-step explanation:

To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53

IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17

{10x-4y=-6

WORK MUST BE SHOWN

Answers

Answer:

x = -1

y = -1

Step-by-step explanation:

10x - 4y =  -6  ---------------------(I)

-3x + 4y =  -1 ---------------------(II)

Add equation (I) & (II) and y will be eliminated.

10x  - 4y = - 6

-3x  + 4y = -1       {Add}

7x           = - 7

         x = -7/7

x = -1

Plugin x =-1 in equation (I)

10*(-1) - 4y = -6

-10 - 4y = -6 {Add 10 to both sides}

     -4y = -6 + 10

     -4y = 4  {Divide both sides by (-4)}

         y = 4/(-4)

y = -1

use the pythagorean theorem to write an equation for the distance Jane's trainer bikes.​

Answers

Complete question is;

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet jane at the end of her run. Use the pythagorean theorem to write an equation for the distance janes trainer bikes

Answer:

x = √(12² + 16²)

Step-by-step explanation:

We are told that;

She bikes from health club to South = 16 miles

From South to West = 12 miles

Her trainer bikes from the health club to meet her at the end which is west.

I have attached a diagram showing this movement in form of a triangle.

From the diagram I attached, I have depicted the distance the trainer bikes as x.

Using pythagoras theorem;

x² = 12² + 16²

x = √(12² + 16²)
