Is triangle a parallelogram

Step-by-step explanation:

Step 1:  Answer the question

This algebraic expression is not a polynomial therefore, none of these options match except D.  The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression.  The expression needs to be expressed as a 7x^2 + 2x + 1.  Therefore, the answer is D.

Answer:  D, none

Answer:

x=33

Step-by-step explanation:

because DC and AB are the same, x must be 33.

Answer:

first you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.

Next, you multiply each separate part — 20 x 7 and 3 x 7.

Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.

Answer:

Mass of each can = 680 grams

Step-by-step explanation:

Mass of a canvas shopping bag  = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms

                                                      = 0.6 Kilograms

Let the mass of each can = w Kilograms

Then the mass of 5 cans = 5w Kilograms

Total mass of the bag when these cans were kept in the bag = 4 Kilograms

(5w + 0.6) = 4

5w + 0.6 - 0.6 = 4 - 0.6

5w = 3.4

w = [tex]\frac{3.4}{5}[/tex]

   = 0.68 Kilograms

   = [tex]0.68\times 1000[/tex]

   = 680 grams

Therefore, mass of each can = 680 grams

Answer:

d

Step-by-step explanation:

Negative 4 (Negative two-fifths + 3 x) is StartFraction 8 over 5 EndFraction minus 12 x, option D is correct.

Two or more expressions with an Equal sign is called as Equation.

The given equation is Negative 4 (Negative two-fifths + 3 x).

-4(-2/5+3x)

We solve the equation by using distributive property.

Now apply distributive property

-4(-2/5)-4(3x)

8/5-12x

StartFraction 8 over 5 EndFraction minus 12 x

Hence, Negative 4 (Negative two-fifths + 3 x) is StartFraction 8 over 5 EndFraction minus 12 x, option D is correct.

Answer: Normal distribution or Gaussian distribution.

Step-by-step explanation:

Normal distribution, this means that we will see something that remaind us to a Gaussian Bell (a curved shape that goes to zero in the extremes and has a maximum in the middle)

If we have some biased points in one side, suppose left, we will have a skewed distribution, that has some important differences with the normal distribution at the time of describe it mathematically.

Answer:

Step-by-step explanation:

To change from a decimal to a fraction  count the number of decimals and add that many zeros after the 1 in the denominator, then simplify

To change a decimal to a percent, move the decimal to places to the right and add a percent sign

To change a fraction to a decimal divide the numerator by the denominator

To change a percent to a decimal move the decimal 2 places to the left and remove the percent sign( if there are fractions, change to a decimal)

113/1000 =                            .113                                    = 11.3 %

Answer:

They claim that 90% of the times, the orders arrive in time.

Then, out of N orders, (90%/100%)*N of them will arrive in time.

Here we have that N = 20

then the number that arrives in time is:

(90%/100%)*20 = 18

Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:

(X/100%)*20 = 16

X = (16/20)*100% = 80%

so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.

Answer:

The second one; x²+7x+12

Step-by-step explanation:

So, since the beginning lengths of the square is x and x, the area of the square is x².

But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).

Finally, you would multiply them together to get the equation you would use to find the new area.

For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.

Here's the work:

Answer:

12

Step-by-step explanation:

5(x+3) = 3(2x-1)

5x+15 = 6x-3

15-3 = 6x-5x

12 = x

x = 12

The number should be 12.

Given that,

Based on the above information, the following equation should be made:

5(x+3) = 3(2x-1)

5x+15 = 6x-3

15-3 = 6x-5x

12 = x

x = 12

Therefore we can conclude that the number is 12.

The required inequality that contains -25 in its solution is y +20 > -30.
Option D is correct.

Number of inequality is given y + 11 > -9 , y - 17≤  -46, 30 ≤ y + 5, y + 20 > -30, the inequality that contains -25 to its solution of set to be determine.

Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

1)  y + 11 > -9
    y >-20
It does not contain -25. in its solution set.

2)  y - 17≤  -46
     y  ≤ -29

It does not contain -25. in its solution set.

3) 30 ≤ y + 5
   25 ≤ y
It does not contain -25. in its solution set.

4) y + 20 > -30
    y  > -50
It does contain -25 in its solution.

Answer:

You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%

Step-by-step explanation:

We use certain functions in writing computer programs.

For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.

For example if she defines that when the player has played for 2hours return an integer 1 for instance.

This value returned will now send a pulse to the CPU to increase its power to 15%.

If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%

RM = 500 yd,

So, by the Pythagoras theorem,

By substituting the values,
