Part 1: How's the weather?

Investigate the weather forecast in your city.

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.

Note: The columns for Day One's subtraction and difference cannot be filled in. As this is the first data point, there is no previous temperature to subtract.

Write a mathematical expression using the information from your table to answer the following questions:


What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.





What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.

Answers

The average change in high temperatures over the next 7 days is 2.3. On the other hand, the average low temperature is 2.8.

How to calculate the average?

To calculate the average of several values, we must perform a two-step mathematical operation:

We must add all the values.We must divide the previous result by the number of values we have.

Below is the example with the values in the table.

High temperature:

1 + 3 + 2 + 2 + 5 + 1 = 1414/6 = 2.3

Low temperature:

3 + 1 + 3 + 4 + 4 + 2 = 1717/6 = 2.8

Alicia had $94 to spend on seven books. After purchasing 7 books that cost the same price, she had $10 left.

Answers

94 - 10 = 84

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.

Step-by-step explanation:

To simplify the expression, open the brackets to obtain your result.

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

A person places $60100 in an investment account earning an annual rate of 5.3%, compounded continuously. Using the formula V = P e r t V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 19 years.

Answers

Answer:

$164516

Step-by-step explanation:

Solution P = 60100 + = 19 r = 5.3/100

V= Pe

V= 60100 e 5.3x19/100

V= $164516

Answer:

164,516.33

Step-by-step explanation:

r = 5.3% = 0.053

p = 60100

t = 19

V = Pe^(rt)

Plug It In:

V = 60100e^0.053(19)

V = 60100e^1.007

V = 164516.3309 ≈ 164516.33

What is the equation of the line that passes through the point (7,-3) and has an undefined slope?

Answers

Answer:

X = 7

Step-by-step explanation:

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.

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.

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.
