What is the Cost of $700 tablet computer that is on sale at 15% off of the local sales tax rate is 4%?

Answer:

Step-by-step explanation:

First, let's look at the pie-shaped segment defined by the 123° angle and the 18.6 m radius.

The area of the entire circle is given by A = πr² = 3.14159(18.6 m)², or A = 1086.865 m².

The area of the "pie slice" is (123/360) of that, or 371.346 m².

Next, we must find the area of the triangle and subtract this area from this 371.346 m²:

Use the Law of Cosines to find the area of this triangle.  The Law of Cosines in appropriate form is

c² = a² + b² -2ab*cos C.

In this case C is 123° and a and b are both 18.6 m in length.  Thus,

c² = (18.6 m)² + (18.6 m)² - 2(18.6 m)(18.6 m)*cos 123°

Thus,

c² = 691.92 m² - 691.92*cos 123°, or

    = (691.92 m²)(1 - cos 123°)

     =  (691.92 m²)(1 - [-0.5446] ) = (691.92 m²)(1.5446) = 1068.767

Taking the square root of this result, we get c = +32.6920 m.

Subdivide the triangle shown to form a new triangle with hypotenuse 18.6 m, adjacent side 32.6920 m  / 2, or  16.3460 and opposite side h.

Then 18.6² = h² + 16.3460², which leads to h²2 = 18.6² - 16.346², or 78.768.

Then h = √78.768 = 8.875 (m).

We now use this info to find the area of the illustrated triangle, using the formula A = (1/2)(base)(height).  That comes out to:

A = (1/2)(16.3460 m)(8.875 m) = 72.535 m²

Finally, we subtract twice that from the area of the 'pie' to get the area of the yellow (shaded) area:

pie area - area of triangle shown in the diagram =

371.346 m² - 145.071 m² = 226.3 m² (to the nearest tenth)

Step-by-step explanation:

Answer:

x=5   x=-3

Step-by-step explanation:

x - 15/x = 2

Multiply each term by x to get rid of the fraction

x(x - 15/x) = 2*x

x^2 -15 = 2x

Subtract 2x from each side

x^2 -2x -15 = 2x-2x

x^2 -2x-15 = 0

Step-by-step explanation:

120 words : 100 seconds = 258 words : x seconds

x = 258*100/120 = 258*5/6 = 43*5/1 = 215 seconds

Answer: 120+120+ 18= 258

You know that it takes 100 seconds for 120 words

120=100 120=100 now we have to find now how many seconds does it take to make 18 words

This question relates to the economic principle of a budget constraint. Jane can afford to purchase up to 5 pizzas with her budget, calculated via: Number of Pizzas = Total Budget / Unit Cost per Pizza.

The subject of this question is related to an economic principle of budget constraint in mathematics. Here, Jane's budget constraint is her total budget of $45, and the unit cost per pizza is $8. The budget works as a restriction that states how many pizzas Jane can afford to buy. The number of pizzas she can buy can be calculated as her total budget divided by the unit cost per pizza.

Therefore, the question is asking you to determine how many pizzas Jane can afford to buy with her budget of $45. Using the formula Number of pizzas = Total budget / Unit cost per pizza, we get: Number of pizzas = $45 / $8 = 5.625.

Since Jane can't buy a fraction of a pizza, she can purchase up to 5 pizzas with her available budget.

Answer:

Table 2

Step-by-step explanation:

The given frequency distribution table is

X  :   1           2           3            4           5

f   :   11          1            2           4           2

The sum of frequencies is

[tex]\sum f=11+1+2+4+2=20[/tex]

The formula for probability is

[tex]P_i=\frac{f_i}{\sum f}[/tex]

where, [tex]f_i[/tex] is frequency and [tex]\sum f[/tex] in the sum of frequencies.

For X=1,

[tex]P_1=\frac{11}{20}=0.55[/tex]

For X=2,

[tex]P_2=\frac{1}{20}=0.05[/tex]

For X=3,

[tex]P_3=\frac{2}{20}=0.1[/tex]

For X=4,

[tex]P_4=\frac{4}{20}=0.2[/tex]

For X=5,

[tex]P_5=\frac{2}{20}=0.1[/tex]

The probability distribution table corresponds with the given frequency distribution table is

X  :   1           2           3            4           5

P   :   0.55    0.05    0.1          0.2       0.1

Therefore, the correct option is 2.

The only probability distribution table that corresponds with the frequency distribution table is; Second table

From the given frequency distribution table, let's find the sum of the given frequencies. Thus;

Σf = 11 + 1 + 2 + 4 + 2

Σf = 20

Now,the probability for each value of x will be;

P_x = f_x/Σf

Where f_x represents the frequency of the given value of x.

Thus;

P_1 = 11/20

P_1 = 0.55

P_2 = 1/20

P_2 = 0.05

P_3 = 2/20

P_3 = 0.1

P_4 = 4/20

P_4 = 0.2

P_5 = 2/20

P_5 = 0.1

Looking at the tables in the options, in conclusion the only tables that have their P value corresponding with those we got for each value of x is Option B which is the second table.

Answer:

Step-by-step explanation:

first solve the volume of the rectangular prism

V = l x w x h

where l is the length

w is the width

h is the height

V = 7 x 4 x 2.5

v = 70 cu cm

then solve the volume of the box

v = e^3

v = 0.5^3

v = 0.125

number of cubes = 70 / 0.125

number of cubes = 560 cubes

Answer:

The number of cubes are needed to fill the rectangular prism = 448 cubes

Step-by-step explanation:

It is given that,

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2 cm. The prism is filled with cubes that have edge lengths of 1/2 cm

To find the volume of rectangular prism

Volume of rectangular prism = Length x Width X Height

Length = 7 cm, Width = 4 cm and height = 2cm

Volume = 7 x 4 x 2 = 56 cm³

To find the volume of small cubes

Volume of cube = a³

a = 1/2 cm = 0.5³ = 0.125

To find the number of cubes needed to fill prism

Number of cubes = Volume of prism/  volume of cube

 = 56/0.125 = 448 cubes

Therefore the correct answer is 448 cubes

Number 7 is A and Number 8 is D.

Answer:

The correct answers are

A) 2+10h

D) 40

Answer: Right (Last option)

Step-by-step explanation:

As you can see in the figure, the parallel lines AD and GJ are intersected  by two lines.

The line EL intersects the parallel lines and there are two angles that are formed by this intersections which are located on the exterior of AD and GJ, but  on opposite sides of EL, (these angles are called "Alternate exterior angles" and they are congruent), which are:

 ∠LHJ and ∠EBA

You can observe that the angle ∠EBA is indicated with a square. This means that the measure of that angle is 90° (Right angle).

Therefore, if ∠EBA=90°, then ∠LHJ =90°

Answer:

The correct answer is last option Right

Step-by-step explanation:

From the figure we can see that,

AD ║ GJ and LE is the traversal.

And also given <ABE = 90°

Fro figure we get <ABE and <GHB are corresponding angles. Corresponding angles are equal.

Therefore <GHB = 90°

To find the <LHJ

From figure we can see that <LHJ and <GHB are vertically opposite angles.

Vertically opposite angles are  equal.

Therefore <LHJ = <GHB = 90°

I may be the second one because the first one says 19 percent of the people who polled that are teachers prefer burgers. And the second one says 19 percent of the teachers polled prefer burgers, so I think it is the second answer.

Answer:

Step-by-step explanation:

First question:  19% of those who prefered burgers were teachers.  This is true.  We focus on the "Burgers" column and ignore the rest of the table.  

Second question:  19% of the teachers polled prefered burgers.  This is false.  If we look at the "teachers" line, we see that 6 teachers prefered pizza and 4 prefered burgers.  The percentage of teachers prefering burgers was 4 / (4+6), or 4/10, or 40%.

Third question (impossible to read):  19% of the people polled prefer ..... .

False.  That 19% does not pertain to the entire group of people polled.

Answer:

To calculate exponential growth, use the formula y(t) = a__ekt, where a is the value at the start, k is the rate of growth or decay, t is time and y(t) is the population's value at time t.

Mark as brainliest please..

To calculate the time for exponential growth, use the formula n = ln(M) / ln(b) for a specific multiple (M) and growth rate (b), or the Rule of 70 for estimating doubling time.

Understanding Exponential Growth

The formula to calculate the time for exponential growth depends on the growth rate and the factor by which a quantity increases. If the growth rate is constant and represented as a percentage or fraction, the growth is exponential. For example, if a bacterial population doubles every hour, starting with 1000 bacteria, it will grow to 2000 after one hour, 4000 after two hours, and so on.

Calculating Time for Exponential Growth

One formula to find the time (n) to reach a certain multiple (M) of the original amount at a specific growth rate (b) is:

n = ln(M) / ln(b)

For instance, to calculate the time to increase by a factor of 1000 with an annual growth rate of 7% (b = 1.07):

n = ln(1000) / ln(1.07) ≈ 102 years

This equation shows that it would take approximately 102 years for the quantity to grow by a factor of 1000.

The Rule of 70

t = 70 / growth rate

t = 70 / 2.9 ≈ 24 years

The time it takes for exponential growth can vary significantly based on the growth rate and the factor of increase desired.
