Hey You!

The formula for area is length × width. So, let's try all of them:

9 × 8 = 72

9 × 9 = 81

9 × 10 = 90

9 × 11 = 99

Judging by all the possible lengths above, the only two answers that would provide an area either equal to 90 of greater than 90 are:

X=10 and X=10

Oh, I could help
You know the formula of area of rectangle
Aire= widthxlength
we have 9x8=72
9x9=81
10x9=90
and 11x9=99
So we have to choose the length 10 or 11

(Will give 1,000 points!) Look at the two 3s in this number:

The only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>

<em />

This question bothers on place values.

<em />

Given the decimal value 89.033, the place value of the blue 3 on the left is the hundredth place (1/100) while the place value of the orange 3 is in the thousandth place(1/1000).

We need to<u> check which of the statement is correct. </u>

For the first option, the blue 3 on the left is 300 times the value of the orange 3 on the right;

  • 1/100 = 300(1/1000)
  • 1/100 = 3/10

Since 0.01≠0.3, hence the first option is wrong

For the second option, the blue 3 on the left is 100 times the value of the orange 3 on the right;

  • 1/100 = 100(1/1000)
  • 1/100 = 1/10

0.01≠0.1, hence the second option is wrong.

The blue 3 on the left is equivalent to the orange 3 on the right is also wrong since they are positioned in a different place

The orange 3 on the right is 1/10 of the value of the blue 3 on the left, is expressed as;

  • 1/1000 = 1/10(1/100)
  • 0.001 = 0.001

Hence the only true statement is <em>"the orange 3 on the right is 1/10 of the value of the blue 3 on the left"</em>

(x+4), (x+12), (x-1) and (x+5) are in proportion. Find the value of x.
mixas84 [53]

Answer:

Find the value of x, if 8,x, x, 50 are in proportion.

If a,b,c and d are in proportion then we have a/b = c/d

Now we need to find the value of x given if 8, x, x, 50 are in proportion.

So we have 8/x = x/50

      Or x x x = 8 x 50

     Or x^2 = 400

     Or x = ±√400

      Or x = ± 20

Therefore the value of x will be + 20 or - 20
