For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?



Remember money is rounded to the nearest hundredth.

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

One side of the triangle is 4 cm, and the sum of the other two sides is equal to a
whole number of cm. What is the smallest possible perimeter of the triangle?
A. 9 cm
B. 10 cm
C. 11 cm
D. 15 cm
E. 17 cm

Answers

Answer:

A) 9 cm

Step-by-step explanation:

By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.

In order to minimize the perimeter, we will assume that 4 cm is the longest side.

Thus, the two remaining sides must be greater than 4.

Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.

Hence, the smallest perimeter possible 9 cm.

Our answer is A.

A 9cm is the answer of this problem

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.

Answer:

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.  

Hope this was helpful!  Have a nice day!  :)

Hello! Answer: 116.64

Step-by-step explanation:

What I did was multiplied 5.4 by 7.2 by 6 and we get a total of 233.28 then we just divide by 2 so...

233.28 ÷ 2 = 116.64 HOPE THAT HELPS!

Answer:

Step-by-step explanation:

To find the volume of a three dimensional shape, you can multiply all three dimensions(length, width, and height).

Volume = 5.4 * 7.2 * 6

Volume = 233.28

If you round to the nearest tenth place, your answer is 233.28 inches cubed . However, if you think about a triangle, the area is base times height divided by two. Similarly, you have to divide the volume by two to get your final answer. Thus, your final answer is (C) 116.64

please help quick!!!

Answers

Answer:

75

Step-by-step explanation:

Volume = 1/2*B*H

So 10 times 3 times 5 divided by 1/2. 10 times 3 is 30, multiplied by 5 is 150.

150 divided by 0.5 (1/2) is 75.

Answer:

x = 2, y = 5

Step-by-step explanation:

Given the 2 equations

y = - 2x + 9 → (1)

y = 4x - 3 → (2)

Substitute y = 4x - 3 into (1)

4x - 3 = - 2x + 9 ( add 2x to both sides )

6x - 3 = 9 ( add 3 to both sides )

6x = 12 ( divide both sides by 6 )x = 2

Substitute x = 2 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 4(2) - 3 = 8 - 3 = 5

Then x = 2, y = 5

The answer is x= 2, y = 5
