Answer:

The decimal disappears

Step-by-step explanation:

0.46 * 50

You can multiply 46 by 50 to get 2300

Then you divide by 100 by moving the decimal point to the left two places because to get from 0.46 to 46, you multiplied by 100, so you use inverse operation.

Need help ASAP !!!!!!!

First we distribute $\frac{1}{5}$ into $n$ and $-\frac{1}{7}$ .

$\frac{1}{5} * n = \frac{1}{5} n$
$\frac{1}{5} * -\frac{1}{7} = - \frac{1}{35}$

That makes the left side of the equation

$\frac{1}{5} n - \frac{1}{35} = \frac{1}{6} n$

Now we subtract $\frac{1}{5}n$ from $\frac{1}{6} n$ , which makes $\frac{1}{30}$

Now the equation is

$-\frac{1}{35} = -\frac{1}{30n}$

Our goal is to isolate $n$ , so we both sides by 30

$30* -\frac{1}{35} = - \frac{1}{30}n * 30$

That will make the equation

$- \frac{30}{35} = -n$

We multiply -1 on both sides of the equation:

$\frac{30}{35} = n$

Finally we simplify $\frac{30}{35}$ , which makes $\frac{6}{7}$

So the answer is $n = \frac{6}{7}$

Check all the statements that are true: A. If a relation is symmetric, it cannot be anti-symmetric. B. The equality relation on

kogti [31]

Answer:

See explaination

Step-by-step explanation:

B. The equality relation on the real numbers is an equivalence relation.

This statement is true

C. If RR is a reflexive relation on a set S, then any two RR- related elements of S must also be R2R2 related.

This statement is true

F. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric

This statement is true

H. If RR is an equivalence relation, then R2

This statement is true

What are the new vertices of triangle ABC if the triangle is translated three units to the right and then three units downward?

DerKrebs [107]

Answer:

A=(0,-1), B=(5,0) and C=(-2,-6)

Step-by-step explanation:

If the translation is 3 units to the right then to every x coordinate we add three and to the y coordinate we subtract 3.

A. 2 cm<br>B. 2√2 cm<br>C. 4 cm<br>D. 4√2 cm

algol [13]

Answer:

.D. 4√2 cm

Step-by-step explanation:

With reference angle 45°

base (b) = 4 cm

hypotenuse (h) = AC

Now

Cos 45° = b /h

1/√2 = 4 / AC

AC = 4√2 cm
