Step-by-step explanation:

According to expanded form, if a number is ABCD then its expanded form will be as follows.

$ABCD = A \times 10^3 + B \times 10^2 + C \times 10^1 + D \times 10^0$

Similarly, the expanded form of 1 ten and 16 ones is as follows.

1 ten and 16 ones = 1 × 10 + 16 × 1

= 10 + 16

= 26

Therefore, the number is 26.

If I'm doing this right, I think you start with 10 and add 16. So you'd have 26. Hope that helped a bit.

The area of square LMNP is 50

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a fixed point which is known as the center of the circle.

A circle is defined if the center and the radius is known.

Analysis:

Perimeter of a circle = 2πr

Given perimeter = 10π

2πr = 10π

2r = 10

r = 10/2 = 5

r = MO

so the diagonal of the square is actually the diameter of the circle = 5+5 = 10

To find the side, x of the square the diagonal and the sides form a right-angled triangle, by Pythagoras, $10^{2}$ = $x^{2}$ + $x^{2}$

2 $x^{2}$ = 100

$x^{2}$ = 100/2 = 50

Also area of square is $x^{2}$ = 50

In conclusion, the area of square LMNP is 50

36/49 = 5/n find n. will mark for whoever answers

Crazy boy [7]

Answer:

n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

eliminate fractions by multiplying by the LCM of the denominators
divide by the coefficient of the variable.

Doing that, we have ...

(49n)(36/49) = (49n)(5/n)

36n = 49·5 = 245 . . . . . simplify

n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

49/36 = n/5

Now, all you need to do is multiply by 5.

n = 5(49/36) = 245/36

Or, you can do both of the original steps at the same time:

(49n/36)(36/49) = (49n/36)(5/n)

n = (49·5)/36 = 245/36

Your younger sibling runs up to you and excitedly exclaims, "I'm thinking of a number. If I add it to the number 2 ten times, th

erik [133]

Answer:

$x = 0$

Step-by-step explanation:

Given

Represent the number with x.

So:

$2 + x + x + x + x + x + x + x + x + x + x = 2$

$2 + 10x = 2$

We want to solve for x

Subtract both sides by 2

$2 - 2 + 10x = 2 - 2$

$10x = 0$

Solve for x

$x = \frac{0}{10}$

$x = 0$

No other number aside 0, satisfy the property.
