Alicia had $94 to spend on seven books. After purchasing 7 books that cost the same price, she had $10 left.
Answers
84/7 = 12
So each book was $12. She purchased seven books so that $84.
$94 - $84 = $10 left
Answer:
Alicia spent $12 on each book.
Step-by-step explanation:
What we know:
- In the beginning, Alicia had $94
- She bought 7 books, that each cost the same price
- After buying the 7 books, she had $10 left over.
What we need to find:
- The cost of an individual book
Steps:
1. To find how much money she spent in total, we must subtract the leftover amount of money ($10) from the amount of money Alicia started with ($94).
94 - 10 = 84
2. Now, we have to figure out how much money Alicia spent on each book. We know that she spent a total of $84. We need to divide that amount by 7 to find the amount that Alicia spent on one book.
84 ÷ 7 = 12
Check your work:
1. Multiply the cost of one book by the number of books Alicia bought.
12 x 7 = 84
2. Find the sum of the amount Alicia spent and the amount of money Alicia had left over. 84 + 10 = 94
The total amount of money Alicia started with was $94, so we can conclude that Alicia did indeed spend $12 on each book.

On a certain hot summer's day, 622 people used the public swimming pool. The
daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $1115.00.
How many children and how many adults swam at the public pool that day?
Answers
Answer:
There were 257 children and 365 adults at the public pool.
Step-by-step explanation:
Let the number of children and adult be x and y respectively,
x+y = 622
1.5x+2y = 1115
Now,
x+y = 622
or, x = 622 - y
Now,
1.5x + 2y= 1115
or, 1.5(622-y) + 2y = 1115
or, 933 - 1.5y + 2y = 1115
or, 933 + 0.5y = 1115
or, 0.5y = 1115-933
or, 0.5y = 182
so, y = 182/0.5
so, y = 365
Now,
x+y = 622
or, x + 365 = 622
so, x = 257

An american man wants to break the guinness Record or largest pizza. He manages to bake with a radius of 66 feet. he offers to feed his town. if he cuts a slice with a central angle of 37* , how much area would this slice cover?
Answers
Answer:
4418.6 square feet
Step-by-step explanation:
The area of a sector of a circle is given by the formula ...
A = 1/2r²θ . . . . where r is the radius, and θ is the central angle in radians
__
The area of the proposed pizza slice is the area of a sector with a radius of 66 ft and a central angle of 37°. That area will be ...
A = 1/2(66 ft)²(37°×π/180°) ≈ 4418.6 ft²
The pizza slice would cover 4,418.6 square feet.
_____
Additional comment
There are 2π radians in the 360° of a circle. That means ...
1 radian = 180°/π ≈ 57.296°
1° = π/180 radians
As we have done above, the number of radians can be found by multiplying the degree measure by π/180°. The units of degrees will cancel, leaving a "pure number" with no units. That is, "radians" is a non-unit: a number of radians is a pure number.

Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.

What does it mean if a number divides another number?.
Answers
Answer:
We say one integer divides another if it does so evenly, that is with a remainder of zero (we sometimes say, "with no remainder," but that is not technically correct). More formally, mathematicians write: If a and b are integers (with a not zero), we say a divides b if there is an integer c such that b = ac.
A number divides another number of the quotient between the second and the first gives an integer number
When a number "divides" another number?
We say that a number n divides another number m if, when we take the quotient between m and n, the outcome is an integer number.
So we should have that:
m/n = integer number.
This also means that a number only can divide another number if this second number is a multiple of the first one, so if we say that (for example).
m/n = 3
Then:
m = 3*n
So m is a multiple of n, which also means that n divides m.

Any line with a undefined slope is a vertical line, which goes up and down.
Since this is a vertical line, and our x-value is 7, this means that the vertical line has the x-coordinate 7 at all times, making the equation x = 7.
