Answer: 0.83

Step-by-step explanation:

14.5/17.5 = 0.828571429

We stop at the 2nd decimal placement after 0.82 but because the following number 8 > 0 we round up the hundredths place which gives us 0.83

Alexander made $742 last week in commission. He made $40068 in commission in 2011.

Sold = $5300

Commission percent = 14%

Commission = 14% of 5300

                     = (14/100)*5300

                     = 14*53

                     = 742

No. of weeks in 2011 = 54

Commission = 54 * 742

                     = 40068

Hence, he makes $742 in weeks and $40068 in year 2011.

There are 2730 ways in which 15 race cars can finish in first, second, and third place.

Let's examine this logically now. Any one of the 15 runners can cross the finish line in first place. You can still have any one of the 14 race cars who are still running finish in second place. Any one of the 13 race cars who haven't crossed the finish line yet can take third place.

As a result, multiplying all the possibilities will give us the number of ways ;

Number of ways =15*14*13

                            =2730

So, the total number of ways in which the race cars finish in first, second, and third place is 2730.

The sequence of transformations is described as follows:

B. Reflection over the y-axis, translation 6 units right and 4 units up, dilation with center (0,0) and scale factor 2.

The two polygons have vertical symmetry, hence the reflection was over the y-axis.

Two equivalent vertices are given as follows:

R(4,-4) and V(2,-4).

After the reflection over the y-axis, the coordinates would be of:

R'(-2,-4).

The polygon increases after the transformation, hence the dilation has a scale factor greater than 1, which is of 2, as VZ = 8, RU = 4.

With a dilation with scale factor of 2, the coordinates of R'' would be given as follows:

R''(-4,-8).

The coordinates of V are:

(2,-4).

Hence the translation is:

Hence option B is correct.

Answer:

Hotdogs: $12

Buns: $6

Altogether (Hotdogs plus Buns): $18

Step-by-step explanation:

She wants 48 hot dogs, and each package contains 8 hotdogs.

48/8 = 6

She'd have to buy 6 packages

6 packages x $2 each = $12

She'd be spending $12 on the hotdogs

She'd also have to get an equivalent amount of buns

Each bag has 12 buns. She needs 48 buns.

48 buns /12 per bag = 4 bags

She would need to buy 4 bags of buns

$1.50 per bag x 4 bags = $6

She'd be spending $6 on buns

Adding the amount she spends on both the buns and hotdogs, she spends $18

Answer:

2³⁰ > 30²

Step-by-step explanation:

Now the values of,

→ 2³⁰ = 1073741824

→ 30² = 900

Then the expression will be,

→ 2³⁰ ? 30²

→ 1073741824 > 900

→ 2³⁰ > 30²

Hence, answer is 2³⁰ > 30².

The decimal division of 18.92 by 11 gives us; 1.72

When dividing decimals  we first of all have to convert the divisor to a whole number by moving the decimal point to the right. Thereafter, we now carry the dividend's decimal point up to the exact same number of places to the right and then divide the resultant numbers in the normal way like in regular long division.

We want to divide 18.92 by 11. Thus, let us apply that rule described above to get;

18.92/11 = 1892/1100

= 1 + (1892 - 1100)/1100

= 1 + (792/1100)

= 1 + 0.72

= 1.72

A new company wants to offer a line queuing service where customers book someone to wait in line on their behalf through a smart phone app.

The possibility that no one wants to pay someone else to wait in line can be represented by the concept of probability.

The probability of an event occurring is defined by probability.

The outcome of an event may be known to us or unknown to us. When this happens we say that there is a chance that the event will happen or not.

We can identify probability by simply dividing the favorable number of possibilities by the entire number of possible outcomes.

Hence, probability is a numerical representation of the chance that a specific event will take place.

The measure of angle 3 = 180 - 120

= 60 degrees

Because the sum of angles on a straight line will be 180 degrees

The measure of angle 6 = 120 degrees

The measure of angle 3 = The measure of angle 7  = 60 degrees

Because the corresponding angle will be equal

The measure of angle 1 = 180-120

= 60 degrees

The measure of angle 2 = 180 - 60

= 120 degrees

Because the sum of angles on a straight line will be 180 degrees

The measure of angle 2 = The measure of angle 5 = 120 degrees

Answer:

  x = 42

Step-by-step explanation:

You want to know the value of x that makes alternate interior angles 105° and (3x-21)° congruent.

When alternate interior angles are congruent, the lines forming them are parallel. Congruent angles have the same measure, so we want ...

  3x -21 = 105

  3x = 126 . . . . . . add 21

  x = 42 . . . . . . . divide by 3

The value of x is 42 when the lines are parallel.

Answer:

0.75

Step-by-step explanation:

because 9/12 is 0.75

Let's establish what this rate indicates through an equation:

inches burned

       hour

Now, plug in the information you have:

inches burned      =          9

       hour                          12

9/12 = 0.75

0.75 inches of the candle is burned per hour

A system of equations to describe this situation is:

c(n) = 25n + 30

c(n) = 15n + 50

The total cost is equal to $80.

The solution to this system of equations is 2.

In order to write a system of equations to describe this situation, we would assign variables to the number of portrait sheets and cost of a photography session respectively, and then translate the word problem into algebraic equation as follows:

The cost for Murray Photography is given by:

c(n) = 25n + 30

The cost for Lasting Memories Company is given by:

c(n) = 15n + 50

Next, we would solve the system of equations as follows:

25n + 30 = 15n + 50

25n - 15n = 50 - 30

10n = 20

n = 20/10

n = 2.

Now, we can calculate the total cost:

c(n) = 25n + 30

c(2) = 25(2) + 30

c(2) = $80.

The quantity of a substance, like salt, that is present in a specific volume of tissue or liquid, like blood, according to science. When there is less water present, the substance becomes more concentrated. You can determine how much solute has been dissolved in the solvent by looking at the concentration of the solution.

Here,

26x + 20(45-x) = 45(24) 

26x -20x = 45(24) -(20(45)
