Answer:

50 tiles

Step-by-step explanation:

The area of a square is the square of the side. The area of each tile is

a = (20 cm)^2 = 20 cm * 20 cm = 400 cm^2

Now we convert 2 square meters into square centimeters.

2 m^2 * (100 cm)/m * (100 cm)/m = 20,000 cm^2

2 m^2 = 20,000 cm^2

Now we divide the total area by the area of one tile.

(20,000 cm^2)/(400 cm^2) = 50

Answer: 10 to the negative second power

Step-by-step explanation: To write 0.01 as a power of 10, first notice that 0.01 is a decimal which means that the exponent on our power of 10 will be negative.

To determine the value of the exponent, count the number of places we would need to move the decimal point in order to get 1.0.

In this problem, we would need to move the decimal point 2 places to get 1.0 which means that the exponent on our power of 10 will b -2.

Therefore, 0.01 can be written as 10 to the negative 2nd power.

get it down to a unit rate firstt by dividing the 129.5 by 7 dvds

$18.50

18.5x2=37

the 2 dvds were 37 dollars

Step-by-step explanation:

The basic operation that is used in finding the cost of n number of products is multiplication, if we know the cost of 1 article then we can find the cost of n numbers of articles by multiplying it with the cost of one article. Therefore, the cost price of 2 DVD's is $37.

Amee buys 7 DVDS for $129.50.

Thus,

The cost price of 7 DVDs is $129.50

We need to find the cost price of 2 DVDs.

First let us find the cost price of 1 DVD.

Therefore,

[tex]7 \;\rm{DVD's}= \$129.50\\1 \; \rm{DVD}=\frac{129.50}{7}\\1 \; \rm{DVD}=\$18.5[/tex]

To find the largest of two numbers when given their product and sum, we can use the quadratic formula.  Let's denote the numbers as 'a' and 'b'. We know that 'a * b = 24' and 'a + b = 10'. We can rewrite the second equation as 'b = 10 - a' and substitute it into the first equation.  Solving the quadratic equation, we find that the larger of the two numbers is 6.

Answer:

a) 20 ways

b) 10 ways

Step-by-step explanation:

When the order of selection/choice matters, we use Permutations to find the number of ways and if the order of selection/choice does not matter, we use Combinations to find the number of ways.

Part a)

We have to chose 2 objects from a group of 5 objects and order of choice matters. This is a problem of permutations, so we have to find 5P2

General formula of permutations of n objects taken r at time is:

[tex]nPr=\frac{n!}{(n-r)!}[/tex]

Using the value of n=5 and r=2, we get:

[tex]5P2=\frac{5!}{(5-2)!} =20[/tex]

Therefore, we can choose 2 objects from a group of 5 given objects if the order of choice matters.

Part b)

Order of choice does not matter in this case, so we will use combinations to find the number of ways of choosing 2 objects from a group of 5 objects which is represented by 5C2.

The general formula of combinations of n objects taken r at a time is:

[tex]nCr=\frac{n!}{r!(n-r)!}[/tex]

Using the value of n=5 and r=2, we get:

[tex]5C2=\frac{5!}{2!(5-2)!} =10[/tex]

Therefore, we can choose 2 objects from a group of 5 given objects if the order of choice does not matters.

Answer:

C. asymptotes

Step-by-step explanation:

In the figure attached, a sign chart is shown. To fill it out you need to find the function's zeros and asymptotes. The zeros are those x values that makes the function equal to zero, in the example, those are the x values that make the denominator equal to zero (x = -1 and x = 5). In a rational function, the asymptotes are those x values that make the numerator equal to zero (x = -9 in the example)

Function in the example:

[tex]\frac{(-2x-2)(2x-10)}{-9x-81} [/tex]

Final answer:

To complete a sign chart accurately, one needs to use test numbers surrounding each of the function's zeros and asymptotes, determining the sign of the function in those intervals. This helps in understanding the behavior of the function and solving inequalities.

Explanation:

To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and C. asymptotes which fills the blank correctly. When you're dealing with functions, especially rational functions, the sign of the function can change around its zeros and asymptotes. Zeros are the points where the function crosses the x-axis, and the function's value is zero. Asymptotes, on the other hand, are lines that the function approaches but never touches; the function's value heads towards positive or negative infinity as it gets close to an asymptote.

When creating a sign chart, you select test numbers from intervals between these critical points -- zeros and asymptotes -- to determine if the function is positive or negative in those intervals. This process helps to understand the behavior of the function across its domain and is essential in solving inequalities.

Here's an example:

Identify the zeros and asymptotes of the function.

Place these values in increasing order on a number line to define test intervals.

Choose a test number from each interval and substitute it into the function to check the sign.

Fill in the sign chart with the corresponding signs for each interval.

Answer:

The central angle ADC = 81°

Step-by-step explanation:

From the figure we can see a circle with circumference = 200 cm and arc ABC length = 45 cm

To find the central angle ADC

Circumference = 200 cm

Length of arc ABC = 45

we have

arc length = circumference * (central angle /360)

central angle = (arc length * 360)/circumference

   = (45 * 360)/200

   = 81 cm

Therefore the central angle ADC = 81°

Answer:the distance to work is 1 mile and you can walk at 4 miles per hour, then you can walk 1 mile in ¼ hr = 15 minutes

Step-by-step explanation:

Dylan,

If the distance to work is 1 mile and you can walk at 4 miles per hour, then you can walk 1 mile in ¼ hr = 15 minutes.

To set up the "equation" think about it this way:  (1 mile/ t) = (4 mile/ 1 hr)

so 1/t = 4/1 hr  

now multiply both sides by t to get 1 = t·(4/1 hr), next divide both sides by (4/1 hr)

t = 1/(4/ 1 hr) = 1 hr/4 = ¼ hr = 15 min.

The answer is 15 minutes because if he can walk 4 miles for only an hour and we know that an hour is 60 minutes

4. 60m

1. 15m

So what I have done there is just divide it by 4 to get one mile and divide 60 by 4 to get the 15 minutes

"The correct operation to perform is the subtraction of the two given polynomial terms:

[tex]\[ \frac{4}{7}x^2 - \frac{3}{2}x^3 \][/tex]

To subtract these terms, we simply combine them, keeping in mind that subtraction requires us to change the sign of the term being subtracted and then add the terms together. Since the terms are already in descending powers of \( x \), we do not need to rearrange them. The subtraction then yields:

[tex]\[ -\frac{3}{2}x^3 + \frac{4}{7}x^2 \][/tex]

Answer:

Step-by-step explanation:

The catch is to put this into the quadratic and solve for a b and c in three equations.

x = 1

a(1)^2 + b(1) + c= 0            

a + b + c + 0                (1)

x = - 1

a(-1)^2 + b(-1) + c = 2

a - b + c = 2                 (2)

x = 2

a(2)^2 + b(2) + c = 8

4a + 2b + c = 8            (3)

===================

Add 1 and 2 together

a + b + c = 0

a - b + c = 2

2a + 2c = 2           Divide by 2

a + c = 1                       (4)  

=====================

Multiply (2) by 2

2a - 2b + 2c = 4          (5)

======================

Add (5) + (3)

2a - 2b + 2c = 4

4a + 2b + c = 8

6a + 3c = 12               (6)

=====================

Multiply (4) by 3

3a + 3c = 3                 (7)

===================

Subtract (7) from (6)

6a + 3c = 12

3a + 3c =  3

Answer:  $183.71

Step-by-step explanation:

Original amount is $5,175.00

1st year: Increase of 9%

→  $5175(1 + 0.09)

=   $5175(1.09)

=  $5640.75

                                       2nd year: Decrease of 5%  

                                       → $5640.75(1 - 0.05)

                                       =  $5640.75(0.95)

                                       = $5358.71

                                                                              Gain: 2nd year - Original  

                                                                               → $5358.71 - $5175.00

                                                                               = $183.71

Answer:

Step-by-step explanation:

We know that $5,175.00 was invested in a stock plan.

It increased by 9% in the first year:

[tex] 9% \times 5175.00 = 465.75 [/tex]

So value reached to (5175 + 465.75 = ) $5640.75

Then it second year, it lost 5% of its value:

[tex] 95% \times 5640.75 = $5358.7 [/tex]
