Answer: The output is 51.5

$51.50 is the cost for Gale and three friends.

Step-by-step explanation:

If the input is 3, substitute 3 for f in the function.

Multiply 12(3)=36

Add 36 to the c.

15.5 + 36 = 51.50

The total cost for Gale and three friends is $51.50

Answer:

Alexis - $8.70

Dominic - $6.31

Charlie - $5.20

Step-by-step explanation:

Answer: The answer is 668.00

Step-by-step explanation: Part one (8 x 2.00)= 16.00 x 41.00 = 656.00 ⇒ ( 8 people, 2.00 per shoes, 41.00 total 656.00)

Part two 1.50 x 8 = 12.00 ( 8 people and 8 sodas for 1,50)

Part three 656.00 + 12.00 = 668.00 ( total price because of the shoes, the two games, the soda and the number of people that had to pay.)

HOPEFULLY THIS HELPS!!!

The expression for the total amount is;

⇒ $16.00 + $32,800 + $12.00 = $32,828

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

They each rent a pair of bowling shoes for $2.00.

They each play two games for a total of 4100.

They each buy a soda for $1.50.

Now,

Cost of shoes for eight friends = 8 x 2.00 = $16.00

And, Cost for playing two games = 8 x 4100 = $32,800

And, Cost of soda for eight friend = 8 x 1.50 = $12

Thus, Total cost = $16.00 + $32,800 + $12.00

                        = $32,828

So, The expression for the total amount is;

⇒ $16.00 + $32,800 + $12.00 = $32,828

Step-by-step explanation:

She mixed up the commutative and associative properties

Line 3 should be commutative and line 4 should be associative.

Line 3 is commutative because she swapped -3.4 and 8.2

Line 4 is associative because of the parenthesis groupings.

Answer:

50000000000

Step-by-step explanation:

For (5×10^– 2): 10 to the negative second power equals -100. 5 x -100 = -500.

For (1×10^– 8): 10 to the negative eighth power equals -100000000. Multiplied by one is obviously the same exact number. So -500 x -100000000 = 5000000000. Remember that negative numbers multiplied by negative numbers will always equal positive numbers. And positive numbers multiplied by negative numbers will always equal negative numbers.

Answer:

The smallest ordinal infinity is that of the positive integers, and any set which has the cardinality of the integers is countably infinite. If a set is too large to be put in one-to-one correspondence with the positive integers, it is called uncountable.

Answer:

Step-by-step explanation:

9x+5y=35

Step 1: Add -5y to both sides.

9x+5y+−5y=35+−5y

9x=−5y+35

Step 2: Divide both sides by 9.

9x9=−5y+359

x=−59y+359

Answer:

x=−59y+359

Let's solve for x.

2x+5y=0

Step 1: Add -5y to both sides.

2x+5y+−5y=0+−5y

2x=−5y

Step 2: Divide both sides by 2.

x=−52y

Answer:

she made 7 batches.

Step-by-step explanation:

1 batch = 2 cups red & 7 cups white

14 cups of red paint = 7 batches

so it would be 7 batches of pink paint.

7 batches of pink paint is needed. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. The following is the structure of an expression: Expression: (Number/Variable, Math Operator, Math Operator)

An accurate arrangement of mathematical symbols that expresses a coherent notion is a mathematical sentence, which is the mathematical equivalent of an English phrase. Verbs appear in sentences.

In the mathematics curriculum and in mathematics in general, algebraic expressions are crucial. Students must be proficient in computations and the manipulation of algebraic expressions in order to advance and perform well in mathematics. They must also be able to read and write expressions.

Given ,

1 batch of pink paint needed 2 cups of red paint and 7 cups if white paint

14 cups of  of red paint

batches of pink paint needed = 14/2

= 7 batches

Therefore 7 batches  of pink paint needed.

Answer: c = [tex]\frac{24}{5}[/tex]

Step-by-step explanation:

Hey there!

Step 1: Cancel 33 on both sides.

24 - 2c = 2c + c

Step 2: Simplify 2c + c to 3c.

24 - 2c = 3c

Step 3: Add 2c to both sides.

24 = 3c + 2c

Step 4: Simplify 3c + 2c to 5c.

24 = 5c

Step 5: Divide both sides by 5

[tex]\frac{24}{5}[/tex] = c

Step 6: Switch Sides.

 In our case,  A   =     2

Can  √ 49 be simplified ?

Yes!   The prime factorization of  49   is

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 49   =  √ 7•7   =
