Answer:

47.1cm

Step-by-step explanation:

multiply 15 cm by 3.14

Given parameters:

 Radius of the pizza  = 15cm

  [tex]\pi[/tex]   = 3.14

Unknown:

Approximate circumference of the pizza = ?

Solution:

 The pizza is circular and we take the circumference of a circle to find that of the pizza;

  Circumference of a circle  = 2  [tex]\pi[/tex] r

Input the parameters and solve;

           Circumference of a circle  = 2 x 3.14 x 15  = 94.2cm

The circumference of the pizza is  94.2cm

Answer:

A isn't parallel but B is

Step-by-step explanation:

I believe A isn't parallel because it's supposed to have the same number but they're one off from each other

B is parallel because when you add the numbers they equal 180 and since they're opposite they'd have to equal 180 in order to be parallel

I hope this made sense :) if it didn't I can try to explain it again

Answer:

5:  a) No  b)Yes

Step-by-step explanation:

5a. You can know by the alternate interior angle converse thm.

The theorem says that if two interior alternate angle are the same then the lines are parallel.

5b.  You can know by the consecutive interior angles thm and the DLD thm.

First use the DLD thm to find the interior angles then use the connsectutive interior angles thm.

3. 6

4. 6

5. 90

6. 90

Step-by-step explanation:

x is greater than or equal to 0, and h is greater than or equal to 0, because since it is ascending, it is constantly getting more time, and getting higher up. The slope is 6, so the change of the feet for the hot air balloon is 6 feet per second, and the h- intercept is 90, so the first time you noticed it, is was at 90 feet, so put your points at (0,90) and at (30, 180)

The factored form of the binomial expansion of 256x4 − 1,536x3y + 3,456x2y2 − 3,456xy3 + 1,296y4 is (4x-6y)^4

Answer:

B

Step-by-step explanation:

Measure of an angle = x

Measure of another angle = x - 143.4

Each angle is the supplement of the other angle .

Which means :-

[tex]x + x - 143.4= 180[/tex]

[tex]2x - 143.4 = 180[/tex]

[tex]2x = 180 + 143.4[/tex]

[tex]2x = 323.4[/tex]

[tex]x = \frac{323.4}{2} [/tex]

[tex]\color{hotpink}x = 161.7[/tex]

Measure of the first angle :-

[tex]\color{hotpink} = 161.7°[/tex]

Measure of the second angle :-

[tex] = x - 143.4[/tex]

[tex] = 16.7 - 143.4[/tex]

[tex]\color{hotpink} = 18.3°[/tex]

As the sum of the measure of each angle adds up to 180° (161.7+18.3=180) , we can conclude that we have found out the correct value of each of the angles .

Therefore , the measure of the first angle is = 161.7° and the measure of it's supplementary angle is = 18.3° .

The correct answer for the given subtraction is:

3.5 - 2.46 = 1.04

Here we want to find the subtraction between two numbers in decimal form:

3.5 - 2.46 = 1.16

Now, this is clearly wrong, as 0.46 is smaller than 0.5, so the decimals after the decimal point are incorrect, now let's solve it again.

First, we can rewrite these two numbers as:

3.5 = 3 + 0.5

2.46 = 2 + 0.46

Then the subtraction can be rewritten as:

3.5  - 2.46

(3 + 0.5) - (2 + 0.46)

Now we group like terms:

(3 - 2) + (0.5 - 0.46)

1 + (0.50 - 0.46)

1 + (0.04)

Now we group that, so we get:

1 + (0.04) = 1.04

This is the correct answer to the given subtraction.

Answer and explanation:

First more than half of the population of the United States do not smoke so the data for smokers in the United States cannot be normally distributed.

Cigs variable does not have a normal distribution in the United States because it is skewed while a Gaussian/normally distributed data is symmetric about it's mean meaning that more values close to the mean occur more frequently. A normally distributed data has more data in the center and is bell shaped while a non normal distribution like the smokers data for US has data skewed to the left or right

Answer:

y = -4/3X - 2

Step-by-step explanation:

Answer:

4x +3y =-6

3y\3y=6-4x/3

y=2-4x

(0,6) & (3,0)

m = (y2-y1)/(x2-x1)

m = (0-6)/(3-0)

m = -6/3

m = -2

Substitute the values in y = mx + c

0 = -2(6) + c

c = 12

Thus, the equation is y = -2x + 12

Answer:

y=2x-6

Step-by-step explanation:

You can plug this into the slope formula, x-intercept of 3 would be (3,0)

and y intercept of -6 would be (0,-6).  

Find the slope using the slope formula. The slope is 2

We are given a y-intercept of -6

therefore, the answer is y=2x-6

Answer:

Jasmine is correct

Step-by-step explanation:

The reason why Jasmine is correct is because, for all whole numbers, there must be a common factor of 1.

So since 1 is a factor of all whole numbers, it means that all numbers have a factor in common which is 1

We can thus conclude that all whole numbers( integers) must have at least one common factor which is 1

Answer:

Solve  :    -x+26 = 0 

 Subtract  26  from both sides of the equation : 

                      -x = -26 

Multiply both sides of the equation by (-1) :  x = 26 

[tex] \frac{2}{5} = \frac{x}{65} [/tex]

[tex]2 \times 65 = 5 \times x[/tex]

[tex]130 = 5x[/tex]

[tex]x = \frac{130}{5} [/tex]

[tex] \color{hotpink}x = 26[/tex]

Therefore , the correct option is :-
