(p -> q) <=> ( (~p) v q )

~p -> ~q <=> p v (~q) //not equivalent
~q -> ~p <=> (~(~q) v ~p) <=> ((~p) v q) //equivalent
q -> p <=> q v (~p) //not equivalent
p -> ~q <=> p v q //not equivalent

answer: ~q -> ~p logically equivalent to p -> q

Hello,
p=>q is equivalent to ~q → ~p

p-------q-------p=>q--~q ----- ~p----~q → ~p
0-------0-------1-------1 ------- 1------- 1
0-------1-------1-------0------- 1------- 1
1-------0-------0-------1------- 0-------0
1-------1-------1-------0------- 0-------1

Column 3= column 6 ==>equivalent

Bella has a credit score of 720. based on the graph, which description most likely explains her score? she pays her bills on tim

Rus_ich [418]

Answer: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score are 720 which is considered a good payment point.

Explanation: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score is 720 which is considered a good payment point.

Explanation: Credit score is known as CIBIL. By this credit, score banks gauge the creditworthiness of a person. The data listed in our credit report CIBIL generate our credit score.

A person's credit history is submitted to CIBIL by banks and other financial institutions on a particular basis.

For example, if a person has a credit score of 600 then that person cannot be considered a good creditor. In this case, the bank doesn't lend him .

Can someone help me with 1-142 all the way to 1-144??

mezya [45]

CL.1.142):

A):

x5 ==> 4 boxes = 3ft <==== x5

20 boxes = ? ft

20 boxes is 15 ft. high

B): x3 ===> 4 boxes = 3ft. <==== x3

? boxes = 9ft.

12 boxes will fit in one stack.

c): CL.143

Perimeter = 15 + 29 + 9 + 11 + 6 + 18 =====> 88m

A1 = b * h

(18)(15)

270m^2

A2 = b * h

(11)(9)

Total Area ======> 270 + 99 ======> 369m^2

CL.1-144

1/4 + 1/4 + 1/5 = 5/20 + 5/20 + 4/20 ====> 14/20

1/4 * 5/5 =====> 5/20

1/5 * 4/4 =====> 4/20

14/20 + ?/20 = 20/20

? = 6 Missing Section

6/20 ======> 3/10

CL-1.145

A): 40/100 = 4/10 ====> 2/5

0.4 ========> 40%

B): 1/6 ======> .00000

0.16 (Repeating 6) ======> 16.6%

C): 37.5/100 = 375/1000 =======> 3/8

0.375 =========> 37.5%

CL-1.146

ADD: 1/6 + 1/2 show all steps:

1/6 + 1/2

1/6 + 3/6

1 + 3 / 6

4/6 =======> 2/3 =======> Decimal: =======> 0.666667

Hope that helps!!!! : )

Below are the rates of travel of 4 shipping trucks. Which truck drove the fastest rate? Truck A: 300 miles in 4 hours Truck B: 2

Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

$v_A=\dfrac{300}{4}\\\\v_A=75\ mph$

Speed of Truck B,

$v_B=\dfrac{240}{3}\\\\v_B=80\ mph$

Speed of Truck C,

$v_C=\dfrac{325}{5}\\\\v_C=65\ mph$

Speed of Truck D,

$v_D=\dfrac{170}{2}\\\\v_D=85\ mph$

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.

Parallelogram efgh has been reflected across the x axis and then rotated 180 degrees around the origin. which of the following t

Brilliant_brown [7]

You are correct, it would be a reflection across the y-axis. I am great at visualizing but for those who are not (Not saying you) all they have to do is cut out a parallelogram and mimic the movements.

Simplify <br> cosx ( tanx+cotx)

Soloha48 [4]

The first step to solving this is to use tan(t) = $\frac{sin(t)}{cos(t)}$ to transform this expression.
cos(x) × $( \frac{sin(x)}{cos(x)} + cot(x) )$
Using cot(t) = $\frac{cos(x)}{sin(x)}$ ,, transform the expression again.
cos(x) × $( \frac{sin(x)}{cos(x)} + \frac{cos(x)}{sin(x)} )$
Next you need to write all numerators above the least common denominator (cos(x)sin(x)).
cos(x) × $\frac{sin(x)^{2} + cos(x)^{2} }{cos(x)sin(x)}$
Using sin(t)² + cos(t)² = 1,, simplify the expression.
cos(x) × $\frac{1}{cos(x)sin(x)}$
Reduce the expression with cos(x).
$\frac{1}{sin(x)}$
Lastly,, use $\frac{1}{sin(t)}$ = csc(t) to transform the expression and find your final answer.
csc(x)
This means that the final answer to this expression is csc(x).
Let me know if you have any further questions.
:)
