You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!

66+81+60+72+79+83+60+92+68 = 661

661 ÷ 9 = 73.44

Mark incorrectly solved the inequality -4(5/2+3/2x) &gt; 8. His work is shown. Which step shows an error based on the inequality
aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

-4(\frac{5}{2}+\frac{3}{2}x)>8

Now solving this expression step by step.

First -4 distributed over parentheses.

(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8

Now solving bracket term, we get:

-10-6x>8

Now taking like terms together, we get:

-6x>8+10

-6x>18

-x>3

Now multiplying this expression by (-1), we get:

x>-3

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8

Find the circumference of the circle with the given area A. Use 3.14 for TI
djverab [1.8K]
Area = r^2 * 3.14
87.9/3.14 = around 28
Square root of 28 = 5.3
The radius is 5.3
Circumference: diameter * 3.14
5.3 + 5.3 = 10.6
10.6 * 3.14 = 33.3
The circumference is 33.3

Teri bought 360 rubber band 2 make a bracelet
Varvara68 [4.7K]

Teri used 130 red bands on the 1st bracelet

Step-by-step explanation:

Teri bought 360 rubber band to make a bracelet

  • 15% of the bands were white and the rest were red
  • After using 140 bands to make her 1st bracelet , 20% of the remaining bands were white

We need to find how many red bands did Teri use on the 1st bracelet

∵ Teri bought 360 rubber bands

∵ 15% of the bands were white

- Find the number of white bands by multiplying 155 by 360

∴ The number of the white bands = 15% × 360

∵ 155 = 15 ÷ 100 = 0.15

∴ The number of the white bands = 0.15 × 360 = 54

∵ She used 140 bands to make the first bracelet

∴ The remaining band = 360 - 140 = 220

∵ 20% of the remaining bands were white

- Find the number remaining white bands by multiplying 20% by 220

∴ The number of remaining white bands = 20% × 220

∵ 20% = 20 ÷ 100 = 0.2

∴ The number of remaining white bands = 0.2 × 220 = 44

- Subtract 44 from 54 to find the number of white bands used

  in the 1st bracelet

∴ The number of white bands in the 1st bracelet = 54 - 44 = 10

∵ The number of bands in the 1st bracelet is 140

∵ 10 of them were white

∴ The number of red bands in the 1st bracelet = 140 - 10 = 130

Teri used 130 red bands on the 1st bracelet

The area of a rectangular piece of land is 2/3 square mile.<br><br> One dimension is 1 1⁄2 miles.
ycow [4]

Answer:

4/9 miles

Step-by-step explanation:

                 \sf Area = \dfrac{2}{3} \ square \ miles\\

               \sf length = 1\dfrac{1}{2}=\dfrac{3}{2} \ miles

\sf Width \ of \ rectangle = \dfrac{Area}{length}

                             \sf = \dfrac{2}{3} \div \ \dfrac{3}{2}\\\\    =\dfrac{2}{3}*\dfrac{2}{3}\\\\   =\dfrac{4}{9} \ miles\\

Use KCF method for faction division.

K- Keep the first fraction.

C - Change the division to multiplication.

F - Flip the second fraction.
