Well, the square root of 2 is about 1.4
So,
$\sqrt{2}$ ≈ 1.4

$12 * 1.4 = 16.8$

arsen [322]

Answer:

See below

Step-by-step explanation:

(a) There is a number whose cube is equal to 2.

$\large \exists x \in \mathbb{R}\;|\;x^3=2$

(b) The square of every number is at least 0.

$\large \forall x\in \mathbb{R},\;x^2\geq 0$

(c) There is a number that is equal to its square.

$\large \exists x \in \mathbb{R}\;|\;x^2=x$

(d) Every number is less than or equal to its square.

$\large \forall x\in \mathbb{R},\;x\leq x^2$

(By the way, this last statement is not true when 0 < x < 1)

What are the answers

dlinn [17]

Answer:

See below

Step-by-step explanation:

The ratio of the secants is the same when set up as full length to external length.

Formula

MN/LN = QN/PN

Givens

LN = 22 + 14 = 36

MN = 14

PN = 32

QN = x

Solution

14/36 = x / (32) Multiply both sides by 32

14*32 / 36 = x Combine 14 and 32

448/36 = x Divide by 36 and switch

x = 12.4

Answers

PN (External) = 13 is the closest answer

Length LN = 36

2. The hundredths model is shaded to represent a division

solniwko [45]

Answer:

Option D

Step-by-step explanation:

If the whole grid is considered to be 1,

Each small grid will value = $\frac{1}{100}=0.01$

There are 72 shaded grids which represent the hundreds = 0.72

When these grids have been divided into 9 equal rows, number of grids in each row = 8

And the value of 8 grids in each row = 0.01 × 8 = 0.08

So the equation is,

0.72 ÷ 9 = 0.08

Therefore, equation represented by the model will be Option (D).
