I'm guessing it is 18. 18 decreased by nine equals nine so to me it makes sense.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,160 ft Determine the​ flag's width and
Illusion [34]

The length of flag is 760 feet and width of flag is 320 feet

<em><u>Solution:</u></em>

A seed company planted a floral mosaic of a national flag

Since, the flag is generally of shape rectangle, we can use the formula of rectangle

Let "a" be the length of rectangle

Let "b" be the width of rectangle

The length is 440 ft greater than the width

Length = 440 + width

a = 440 + b ----- eqn 1

The perimeter of the flag is 2,160 ft

<em><u>The perimeter of rectangle is given as:</u></em>

Perimeter = 2(length + width)

Substituting the given values, we get

2160 = 2(440 + b + b)

2160 = 880 + 4b

4b = 2160 - 880

4b = 1280

b = 320

<em><u>Substitute b = 320 in eqn 1</u></em>

a = 440 + 320

a = 760

Thus the length of flag is 760 feet and width of flag is 320 feet

Which of the following is true of histograms? (Check all that apply.)
Leviafan [203]

1:

A - actually not true, a probability plot would be better

B - not true, since exact values are plotted a box-and-whisker would be better

C - true (that's what a histogram does)

D - True (You can get the measures of central tendency quickly)

2:

A - true

B - False - those are easily found

C - False - They are arranged on the x-axis

D - True - see above

5x + 10 = 20
Andrei [34K]

To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.

Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.

On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.

Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.
