Sami purchased 5 comic books priced as shown.

$4.50 $3.75 $3.95 $2.19 $3.24
If sales tax is 9%, what is the total price Sami paid? Round to the nearest cent, if necessary.

Answers

Answer:

$19.23

Step-by-step explanation:

First, add the prices of all 5 comics together. That should equal $17.63. The tax is 9% so that would be 1.5867 or $1.60. In total, Sami paid $19.23.

19.21

adding all the totals together gives you 17.63 . the sales tax is 1.5867 . add that to the 17.63 and you’ll get 19.21

Which expression best defines a rational number?

B. has a decimal form that cannot be rounded
C. has a decimal form that is terminating or repeating
D. has a decimal form that is nonterminating and nonrepeating

Answers

A for sure because it can be

Rational numbers are terminating or repeating numbers. Therefore, option C is the correct answer.

We need to check from the options which expression best defines a rational number.

What are rational numbers?

Rational numbers: Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Rational numbers can be easily identified with the help of the following characteristics.

All integers, whole numbers, natural numbers, and fractions with integers are rational numbers.If the decimal form of the number is terminating or recurring as in the case of 5.6 or 2.141414, we know that they are rational numbers.In case, the decimals seem to be never-ending or non-recurring, then these are called irrational numbers.

So, from the definition, we understood that rational numbers are terminating or repeating numbers.

Therefore, option C is the correct answer.

If you are making 2/4 of the recipe, you multiply 2/3 by 2/4.

If you are making 2/4 of the recipe, you need 1/3 cups of sugar.

9514 1404 393

Answer:

4/12 cups

Step-by-step explanation:

The amount needed is the product of the recipe amount and the amount of a recipe that is being made.

(2/3 cup/recipe)(2/4 recipe) = (2·2)/(3·4) cups = 4/12 cups

The fraction can be reduced to 1/3 cup, but we're told not to reduce it.

Ashley has a total of $35 to spend at the carnival this year. She wants to purchase a turkey leg for $12, also. If each ride costs $0.50, how many rides can Ashley get on? IDENTIFY THE CONSTANT.

Answers

Answer:

46 rides; the constant is the $12 turkey leg

Step-by-step explanation:

To solve this, you can write an equation:

c = .5r + 12

where c is cost and r is rides (the constant is 12 because it doesn't change)

You already know that the cost is 35, so you just need to plug it in and solve:

c = .5r + 12; c = 35

35 = .5r + 12

23 = .5r

r = 46

So, on $35 and an expense of $12, Ashley can ride 46 rides.

Answer:

Ashley can go on 46 rides

Step-by-step explanation:

12+0.50x=35

-12 -12

0.50x=23

0.50x/0.50= 23/0.50

x=46

What is the measure of x?

Answers

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9

Answer:

The only one I can see right now is (C)

Step-by-step explanation:

Because a positive divided by a negative is negative, so 80/-10 is -8.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.

The expressions that are equivalent to –8 is only option C i. e 80 ÷ (–10)

What is Expression?

Expression is a combination of operators, variables and numbers

Two expressions are said to be equivalent when we solve both we get the same answer.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers

For option C, –8 is equivalent to 80/-10 because a positive divided by a negative is negative, so 80/-10 is -8.

For option D, –8 is not equivalent to -80/-10 because a positive divided by a positive is positive, so -80/-10 is 8.

So option C is equivalent to -8.
