Is the number 3 squared rational?

Answers

Answer 1
Yes The square of any rational number is rational.
Answer 2
No it isn’t


there is always an odd exponent. So it could not have been made by squaring a rational number.This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number. In other words, the square root of 2 is irrational.

6(3p – 2) = 24

Answers

Answer:

p= 2

Step-by-step explanation:

So first you want to distribute the 6 to 3p-2 which basically means multiply

6(3p – 2) = 24

6 times 3p is 18 and 6 time -2 is -12

* remember a negative and a positive equal a negative*

18p-12=24

you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36

18p = 36

since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2

so p = 2

if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it  was like 18 + p you can subtract because 18 and p arent together

If 50 percent of Q is 20 percent of P, then P is what percent of Q​

Answers

Answer:

P is 250% of Q

Step-by-step explanation:

50/100 Q  =   20/100P            Multiply both sides by 100

50Q = 20 P                              Divide by 20

50/20 Q = P

2.5 Q = P

So P is 2.5 times the size of Q.

2.5 as a percent is 250 %

What is the net decimal equivalent if 40%, 30% and 15% discounts were applied

Answers

Answer:

Well you can’t really stack these percentages discounts.

Assuming it’s in the same order as the problem then

We can find the decimal equivalent by just dividing.

So think of it like this way.

Your getting 40 percent off, the original price.
The original price of course is a 100 percent since its the one and only price.

When your taking 0.4 percent off then its taking off 0.4 from the 1.00

So you have 0.6.

Your now paying 60 percent of the price.

Now the 30 percent.
Same thing except this times its 0.6.

Now 30 percent of 60 is 18 percent and then subtract that by 0.6 which is 0.42

Now for the final 15 percent
Same thing except this time its 0.15

15 percent of 0.42 is 6.3 percent, subtract that by 0.42 is 0.357

After the discounts were applied you’d only have to pay 0.357 or 35.7%

In order to find the total amount of discounts just subtract the amount we have to pay by the original which was 100 %. 100 - 35.7 = 64.3

Final net percentage is equivalent 64.3%

What is the x-intercept of the line 3x – 7y = 42?
PLEASE HELP

Answers

Answer:   x-intercept = 42/3 = 14

Step-by-step explanation:  y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000

 y-intercept = 42/-7 = 6/-1  = -6.00000

When y = 0 the value of x is 14/1 Our line therefore "cuts" the x axis at x=14.00000

 x-intercept = 42/3  =  14

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.143. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.143 - (-6.000) = 0.857 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.857/2.000 =  0.429

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  3x-7y-42  = 0 and calculate its properties

x-intercept = 42/3 = 14
