Answer:
x = 8.64
Step-by-step explanation:
12% of 72 = (12/100) * 72/x
= 0.12 * 72
x = 8.64
8.64 is 12% of 72. Determining any kind of percentage will not be a challenge for anybody if the above procedure is followed step by step.

Write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5
Write 1/1,024 as an expression using a negative exponent other than -1
Answer:
[tex]\frac{1}{2^{10}}=2^{-10}[/tex]
Step-by-step explanation:
[tex]\frac{1}{1024}[/tex]
To get the expression with negative exponent , we need to convert the number 1024 in exponential form
[tex]1024= 2^5 \cdot 2^5= 2^{10}[/tex]
Replace the denominator by 2^10
[tex]\frac{1}{2^{10}}[/tex]
Now we apply exponential property
[tex]\frac{1}{a^m} =a^{-m}[/tex]
[tex]\frac{1}{2^{10}}=2^{-10}[/tex]
negative exponent other than -1 is [tex]\frac{1}{2^{10}}=2^{-10}[/tex]

A boa constrictor is 18 inches long at birth and grows 8 inches per year. Write an equation that represents the length Y (in feet) of a boa constrictor that is X years old.
This is writing equations in slope intercept form and I tried y=8x+18 but it didn't work.
Final answer:
The length Y (in feet) of a boa constrictor that is X years old is given by the equation Y = 0.6667X + 1.5. This equation takes into account the initial length of 1.5 feet at birth and an annual growth of 0.6667 feet.
Explanation:
To write an equation representing the length Y (in feet) of a boa constrictor that is X years old, we need to start with its initial length at birth and account for its growth over the years. The boa constrictor is 18 inches long at birth and grows 8 inches per year. However, we want Y to be in feet, so we must convert these measurements from inches to feet (since 1 foot = 12 inches).
To convert the initial length from inches to feet, we divide 18 inches by 12, which gives us 1.5 feet. The annual growth should also be converted from inches to feet by dividing 8 inches by 12, resulting in approximately 0.6667 feet.
So, using slope-intercept form (Y = mx + b), our equation is:
Y = 0.6667X + 1.5
This equation states that the boa constrictor starts with a length of 1.5 feet at birth (Y-intercept) and grows about 0.6667 feet for every year that passes (the slope).
balance the equation out by filling in the blank for the missing number

Antoine and 3 friends divide some pennies evenly among themselves. Each friend separates his pennies into 3 equal stacks with 5 pennies in each stack. write a multiplication sentence that shows
Answer:
4 × ( 3 × 5 ) = 60
Step-by-step explanation:
Answer:
4 × (3 × 5) = 60
Step-by-step explanation:
Total number of persons including Antony = 4
Number of stacks separated by each friend = 3
Number of pennies in each stack = 5
Number of pennies in all 3 stacks of one friend = 3 × 5
Number of pennies in all 3 stacks of 4 persons = 4 × (3 × 5) = 60
Hence, the multiplication sentence is 4 × (3 × 5) = 60.
Which variable expression represents the word phrase? the sum of 12 and the quotient of 9 and a number
Answer:
The required expression is [tex]12+\frac{9}{y}[/tex].
Step-by-step explanation:
Consider the provided phrase.
The sum of 12 and the quotient of 9 and a number
Let the number is y and the quotient of 9 and a number can be written as:
[tex]\frac{9}{y}[/tex]
Thus, the sum of 12 and the quotient of 9 and a number can be written as:
[tex]12+\frac{9}{y}[/tex]
Hence, the required expression is [tex]12+\frac{9}{y}[/tex].

If you can buy 1⁄3 of a pound of turkey for 4 dollars, how much can you purchase for 10 dollars? Write your answer as a fraction of a pound.
Answer:
[tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 3 meter per second or 4 miles per hour.
As per the statement:
If you can buy 1⁄3 of a pound of turkey for 4 dollars
by definition of unit rate we have;
[tex]\text{Unit rate per dollars} = \frac{\frac{1}{3} }{4} = \frac{1}{12}[/tex] pound of turkey.
We have to find how much can you purchase for 10 dollars.
[tex]\text{Weight of turkey for 10 dollars} = \text{Unit rate per dollars} \times 10[/tex]
⇒[tex]\text{Weight of turkey for 10 dollars}=\frac{1}{12} \times 10 = \frac{5}{6}[/tex] pound
Therefore, [tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars

A expression like ( 3+5) × (4-1) is a combination of numbers and at least one operation. Fill in the blank
An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation.
Explanation:An expression like (3+5) × (4-1) is a combination of numbers and at least one operation. In this expression, the numbers 3, 5, 4, and 1 are combined using the addition and subtraction operations. The addition operation is represented by the symbol '+', and the subtraction operation is represented by the symbol '-'. The expression can be simplified by performing the operations in the parentheses first, then applying the multiplication operation:
(3+5) × (4-1) = 8 × 3 = 24
