Help!!!Geometry chapter three

Can i please get help with this question?

Aleonysh [2.5K]

1,5 . n = 13,65

We know:

$1,5=\frac{15}{10}$

and

$13,65=\frac{1365}{100}$

So,

$\frac{15}{10}.n=\frac{1365}{100}$

Pass $\frac{15}{10}$ as division.

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

Btw, we also know:

$\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}$

So,

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

$n = \frac{1365.10}{100.15}$

$n = \frac{13650}{1500}$

$n = \frac{91}{10}$

$n = 9,1$

Let D = {-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36} Determine which of the following statements are true and which are false. a)

morpeh [17]

Answer:

$\forall x\in D$ if x is odd then x> 0 is true statement.

$\forall x\in D$ if x is even then x≤0 is false statement.

$\forall x\in D$ If the ones digit of x is 2, then the tens digit is 3 or 4 is true statement.

$\forall x\in D$ if the ones digit of x is 6, then the tens digit is 1 or 2 is false statement.

Step-by-step explanation:

Consider the provided information.

D = {-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36}

Part (A) $\forall x\in D$ if x is odd then x> 0

Here only even numbers are less than 0 that means the statement is true.

$\forall x\in D$ if x is odd then x> 0 is true statement.

Part (B) $\forall x\in D$ if x is less than 0 then x is even.

Here only even numbers are less than 0 that means the statement is true.

$\forall x\in D$ if x is odd then x> 0 is true statement.

Part (C) $\forall x\in D$ if x is even then x≤0

Here we can see that 16, 26, 32, 36 are even number and also greater than 0. Thus the statement is false.

$\forall x\in D$ if x is even then x≤0 is false statement.

Part (D) $\forall x\in D$ If the ones digit of x is 2, then the tens digit is 3 or 4.

There is only one number whose ones digit is 2. i.e. 32 also the tens digit of the number 32 is 3. Which makes the above statement true.

$\forall x\in D$ If the ones digit of x is 2, then the tens digit is 3 or 4 is true statement.

Part (E) $\forall x\in D$ if the ones digit of x is 6, then the tens digit is 1 or 2.

Numbers having ones digit 6 are: 16, 26 and 36

Here, the tens digits are 1, 2 and 3 which is contradict to our statement. Hence the provided statement is false.

$\forall x\in D$ if the ones digit of x is 6, then the tens digit is 1 or 2 is false statement.

Which function is represented by the graph

krek1111 [17]

Answer: y = -2|x| + 1

Step-by-step explanation: it is an absolute value function, y = |x|, moved up one. then we see that it has been flipped. it has also been vertically stretched by a factor of 2.

10 free points if you know answer to the question. always loooking to make peoples days better!

ira [324]

What you need to know in order to answer this:

   In math, the symbol " ! " is used to indicate "factorial".
   "Factorial" means the product of the integers from 1
   up to the number.

Examples:

2 ! = "two factorial" = 1 * 2 = 2

4 ! = "four factorial" = 1 * 2 * 3 * 4 = 24

For this question:

10 ! = "ten factorial" = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10

   = 3,628,800 .

If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.

And by the way, the points aren't 'free'. I had to
give you some information in order to earn them.

Calculate the equivalent decimals for the following fractions.

Lapatulllka [165]

Answer:

a. 0.25

b. 0.4

c. 0.66 repeating

d. 0.75

Step-by-step explanation:

a. 1/4 is equal to one quarter which is 0.25

b. 2/5 is equal to 4/10 which equals 0.40 or 0.4

c. 2/3 is 0.6666666 and goes on forever so we would call that a repeating decimal

d. 3/4 is equal to three quarters which would be 0.75

i hope this helps :)
