Find the sum of all 3 digit whole numbers that arw divisible by 13 ?

GuDViN [60]

We have an arithmetic sequence with

a0 = 1st 3-digit number divisible by 13 
a0 = 104 
d = 13 (why?) 
last term is largest divisible by 13 = 988 
how many terms? (988-104)/13 + 1 = 69 

S = 69/2(104+988) = 37674

For the law of cosines How am I supposed to know if I’m using SAS or SSS

seropon [69]

Answer:

SSS congruency is when you know that the two triangle you want to compare's sides have the same length. Since they have the same length, they are congruent. SAS congruency stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.

Formalize the following argument by using the given predicates and then rewriting the argument as a numbered sequence of stateme

sergiy2304 [10]

Answer:

The answer is " $\bold{((P_2 \wedge P_3)\longrightarrow P_1 \longrightarrow P_1 }$ ".

Step-by-step explanation:

Let assuming the following predicates:

$\to B(x,y)= \text{x barks at y} \\\\\to D (x)= \text{x is a dog} \\\\\to C (x)= \text{x is a cat} \\\\$

In the given table it calculates the numbered sequence, which is given in the statement and calculates the other details, please find the attached file.

Premise P1 means whether dogs are shouting at cats.

Premise P2 means Maximum is a dog.

Premise P3 means that a cat is Moonbeam.

Unless the assumptions P1, P2, and P3 all are valid, otherwise the conclusion that Maximum starts barking at Moonbeam also is correct.

By both the law of deduction of Modus Ponens, statement 4 is the interpretation of states 1, 2, and 3. That conclusion can thus be conveyed as follows:

so, the final answer is " $\bold{((P_2 \wedge P_3)\longrightarrow P_1 \longrightarrow P_1 }$ "
