Fandango has movie tickets on sale for 1\2 price. You buy 2 $12 tickets and you must pay 6% sales tax. What is your total cost after discount and taxes?
Answer:
$12.72 or $25.44
Step-by-step explanation:
if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question dosent specify that.

It costs $13 to rent a canoe and $5.50 to use the canoe for an hour. You have $29.50. Write an equation that represents the number $h$ of hours you can rent the canoe.
Answer:
Step-by-step explanation:
The base number is 13 dollars since you must pay it before adding hourly expenses.
Every hour, you have to pay 5.50.
So, the total cost would equal:
29.50 - (13 + 5.5h) < 29.50
Think: you have 29.50. you must pay 13 dollars before using it. it costs 5.50 for each hour. your money must be less than your total.
Hope this helped :)

FORMULA?
a store is having a sale on almonds and jellybeans for 2 pounds of almonds and 3 pounds of jellybeans the total cost is $15 for 6 pounds of almonds and 5 pounds of jellybeans total total cost is $35 find the cost of each pound of almonds and each pound of jellybeans
Answer:
$5.50 + $10.50 = $16
Step-by-step explanation:
6a + 5b = $34
2a + 3b = $16
...Solving by elimination
6a + 5b = 34
-3(2a + 3b = 16)
-4b = -14
b = 14/4 0r $3.50, cost of each pound of jelly beans.
a,cost of each pound of almonds = $2.75 %2816-+3%283.50%29%29%2F2+=+2.75
...checking Using:
2a + 3b = $16
$5.50 + $10.50 = $16
Solve for x if 6(X + 3) = 36 *
Answer:
6( X + 3 ) = 36
6X + 18 = 36
6X = 36 - 18
X = 18 ÷ 6
X = 3
Thus, the value of X is 3.
Hope it helps,
Thank You.
Answer:
Step-by-step explanation:
6x +18=36
6x+18-18=36-18
6x=18
6x divide by 6 =18 divide 6
x=3

Answer/Step-by-step explanation:
To simplify the given expressions that involves negative exponent, recall the law of exponents that deals with simplifying negative exponent.
Thus: [tex] a^{-x} = \frac{1}{a^x} [/tex]
Ally this rule in solving the given problem as follows:
Red blood cell = [tex] 125,000^{-1} = \frac{1}{125,000^1} = \frac{1}{125,000} = 0.000008 = 8*10^{-6} [/tex]
White blood cells = [tex] 3(500)^{-2} = 3(\frac{1}{500^2}) = 3(\frac{1}{250,000}) = 3*0.000004 = 0.000012 = 1.2*10^{-5} [/tex]
Platelet = [tex] 3(1000)^{-2} = 3(\frac{1}{1,000^2}) = 3(\frac{1}{1,000,000}) = 3*0.000001 = 0.000003 = 3*10^{-6} [/tex]
Bethany wants to estimate the value of (4.296 times 10 Superscript 11) (1.8614 times 10 Superscript negative 14). Which statement about the estimate is true?
Answer:
D. The number will be less than 1 because when adding the exponents,
11 + (-14) = -3, and a number in scientific notation with a negative exponent is less than 1.
Step-by-step explanation:
The question lacks appropriate option. Find the options below;
A. The value will be greater than 1 because 4.296 x 10^11 is a very large number and multiplication always increases the size of a number.
B. The value will be greater than 1 because 4 x 2 = 8 and 8 is larger than 1.
C. The value will be less than 1 because (4.296 x 10^11) x (1.8614 x 10^-14) will be a negative number. All negative numbers are less than one.
D. The number will be less than 1 because when adding the exponents,
11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.
Given the expression [tex](4.296*10^{11})(1.8614*10^{-14})[/tex], to expand the expression we will apply some of the law of indices below. If a, b and m are integers
[tex]a^m*a^n = a^{a+m}[/tex]
[tex]= (4.296*10^{11})(1.8614*10^{-14})\\\\= (4.296*1.8614)(10^{11}*10^{-14}) \\\\= 7.9965744 * 10^{11}*10^{-14}\\sum \ up \ the\ power\ of\ the \ exponents\\\\= 7.9965744 *10^{11-14}\\\\= 7.9965744 *10^{-3}\\[/tex]
= 0.0079965744
Based on the result, it can be seen that the resulting value is less than 1 due to the negative power of its exponent (i.e -3). Any scientific notation having a negative exponent always returns a value that is less than 1.
Answer:
The number will be less than 1 because when adding the exponents, 11 + (negative 14) = negative 3, and a number in scientific notation with a negative exponent is less than 1.

Juan added a set of parentheses and a set of brackets in the expression: 15: 3 x 5 + 4 x 8. Juan's expression has a value of 40. What is one way Juan could have written the grouping symbols?
Answer:
[tex][15: (3 \times 5) + 4] \times 8[/tex]
Step-by-step explanation:
First of all, let us have a look at the rule for solving brackets/parentheses/algebraic operations.
The rule states that the expression must be solved in the following order:
B - Brackets (Innermost parentheses first, then the enclosing brackets are solved)
O - Of (for example 10% of 20)
D - Divide operation
M - Multiplication operation
A - Addition operation
S - Subtraction operation
So, we need to add a set of parentheses i.e. () and a set of brackets i.e. [] in the expression:
[tex]15: 3 \times 5 + 4 \times 8[/tex] such that the result is 40.
Consider the expression: [tex][15: (3 \times 5) + 4] \times 8[/tex]
Let us try to solve the expression using the above rule:
[tex][15: (3 \times 5) + 4] \times 8[/tex]
First of all, the innermost () will be solved:
[tex](3\times 5) = 15[/tex]
Now, the expression becomes:
[tex][15: 15 + 4] \times 8[/tex]
Now, 15:15 will be solved as 1
[tex][1+ 4] \times 8[/tex]
Now, the outer [] will be solved:
[tex]5\times 8 = 40[/tex]
Hence, the correct answer is:
[tex][15: (3 \times 5) + 4] \times 8[/tex]

Find the prime factors of 60 by dividing by prime numbers.
Let's start with the smallest prime number 2
60/2 = 30
Divide that result over 2
30/2 = 15
We can't divide this by 2 because 15/2 = 7.5 isn't a whole number
Let's move onto 3
15/3 = 5
The result is a prime number, so we stop.
The values we divided as denominators were: {2, 2, 3}
We add the result 5 to the set to completely list all of the prime factors of 60
The prime factorization would be
60 = 2*2*3*5which is the same as saying
60 = 2^2*3*5Please hell will give branilest to the firstanswer s
Answer:
[tex]x=13[/tex]
Step-by-step explanation:
The perimeter of a rectangle is given by the formula:
[tex]P=2l+2w[/tex]
Where l is the length and w is the width.
We know that the perimeter is 80. Looking at the rectangle, we can also see that the length is 2x+3 while the width is x-2. Thus, make the substitutions:
[tex]P=2l+2w\\80=2(2x+3)+2(x-2)[/tex]
Distribute:
[tex]80=4x+6+2x-4[/tex]
Combine like terms and add:
[tex]80=6x+2[/tex]
Subtract 2 from both sides:
[tex]78=6x[/tex]
Divide both side by 6:
[tex]x=13[/tex]
Thus, the value of x is 13.

The addition property of equality and then the division property of equality is the sequence which describes the inverse operations used
for steps 2 and 3 to solve the linear equation
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given Linear equation is -1/2 (6x + 10) = 13
Minus one by two times of six x plus ten equal to thirteen
Step 1: –3x – 5 = 13
By addition property we add +5 on both the sides
Step 2: –3x = 18
By division property we divide both sides by -3
Step 3: x = –6
Hence, the addition property of equality and then the division property of equality is the sequence which describes the inverse operations used
for steps 2 and 3 to solve the linear equation
