One serving of kettle corn has 180 calories and a mass of 30 grams. How many calorie are in 5 grams of the kettle corn?



a. 6

b. 10

c. 30

d. 36

Answers

The answer is 30 I believe

Answer:

30 calories.

Step-by-step explanation:

First we need to know how many is one gram so do 180/30 to get 6. Then, since we are looking for the amount in 5 grams, multiply 6 by 5 to get 30.

Therefore, there are 30 calories in 5 grams.

Add: a² + b² + c² – 3abc and a² – b² + c² + abc


2. Add: xy² + 4x²y – 7x²y - 3xy² + 3 and x²y + xy²


3. Add: 5x² + 7y - 6z² ; 4y + 3x² ; 9x² + 2z² - 9y and 2y - 2x².


4. From the sum of 3x - 2y + 4z and 3y – 2z, subtract x - y - z.


5. Subtract a – 2b – c from the sum of 3a – b + c and a + b – 3c.


6. The sum of two expressions is 3x2 + 2xy – y2. If one of them is 2x2 + 3y2, find the other.
7. From the sum of 4b2 + 5bc, -2b2 – 2bc – 2z2 and 2bc + 4c2, subtract the sum of 5b2 – c2 and -3b2 + 2bc + c2.
8. What should be subtracted from 3x + 5y + 9 to get - 2x + 3y + 15?

9. Subtract 2m – 5q + 7 from 4p + 2q and add your result to m2 – 3m3 + m - 1.

10. Subtract 2a2b – 3b2 from 3a2 – 5ab2 + 2b2 and subtract your result from the sum of the two expressions 3ab2 + 5b2 – 2a2b and a2b + 5a2 – 3ab2

7. Sum of 4b2+5bc ; -2b^2-2bc-2c^2 ; 2bc+4c^2 is (2b^2+2c2)
Sum of 5b^2-c^2 and -3b^2+2bc +c^2 is (2b^2-2bc)

1) Explain how angles are measured.

Answers

angles are measured in degrees (°), using a protractor. an angle is usually formed by the two rays or arms at a common vertex.

Help pleaseee.The answer has to be 50,40, or 90

Answers

Answer:

40

Step-by-step explanation:

We know that angle FGE is equal to 50 and angle GEC is equal to 90 degrees because of the square. Therefore, we add them together. 50+90=140. We know that a triangle is equal to 180 degrees so we have to subtract 140 from 180. 180-140 is equal to 40. Therefore, angle FCE is equal to 40.

If this has helped you please mark as brainliest

Answer:

<FCE = 40

Step-by-step explanation:

The sum of angles in a triangle is (180) degrees. This holds true for the given triangle. Therefore, one can form an equation,

<FGE + <FCE + <GEC = 180

Substitute,

50 + <FCE + 90 = 180

(Note that a box around an angle indicates that the angle measure is (90) degrees)

Simplify,

140 + m<FCE = 180

Inverse operations,

140 + <FCE = 180

<FCE = 40

which model shows 9 (3+6) = (9 x 3) + (9 x 6)?

NO LINKS OR FILES THANK YOU!!

Answers

Answer:

Look at the image.

Step-by-step explanation:

The required model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B. Option B is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

What is an array?

The array is a collection of things and shapes in a specific pattern.

Here,

Given that, to determine the model that represents 9 (3+6) = (9 x 3) + (9 x 6)

So 9 (3+6) = (9 x 3) + (9 x 6) represents the arrangement of squares in array form,

If in a pattern there are 9 rows there must be 3 and 6 columns or vice versa.,

So from the above definition, a model that represents 9 (3+6) = (9 x 3) + (9 x 6) is given in the model shown in B.

Answers

Answer:

2 dollars

Step-by-step explanation:

Answer:

$1.72

Step-by-step explanation:

First, subtract the cupcake from the total

44.03-2.75=41.28

Find out the total number of cookies

8+16=24

Then divide the total cookie price by the total number of cookies

41.28÷24=1.72

Each cookie costs $1.72
