The pair of polygons is similar. Find the value of x

Answers

Answer:

The value of x is 3

Step-by-step explanation:

If they area similar, then the ratio of the sides are equal

Mathematically;

x+ 1/3x + 1 = 8/20

20(x + 1) = 8(3x + 1)

20x + 20 = 24x + 8

24x-20x = 20-8

4x = 12

x = 12/4

x = 3

1.All states have ways in which they are able to collect revenue. Some states collect a significant amount of revenue through sales tax, while others take in large
portions of revenue through other kinds of taxes, such as property taxes and state income taxes.


2. You will pay the same tax rate from state to state and for the same classes/types of goods.


3. 5 states do not levy a statewide sales tax: New Hampshire, Oregon, Montana, Alaska, and Delaware.


4. States, such as Pennsylvania, can impose a sales tax on goods and that tax rate can increase if local governments within the state also levarge a sales tax to
collect revenue.

Answers

Answers:

True. All states have a different approach to collecting revenue, which is money they spend on government programs. Most states have income taxes, but a state like Florida doesn't have income taxes. Instead they rely on sales taxes and property taxes. The general rule is that if one tax is missing, then chances are the other tax rates are higher to make up the lack of funds (that the missing taxes would provide).False. States vary in sales tax rates. For instance, Alabama's sales tax is 4% while Arkansas is 6.5%True. You can do an online search of "states without sales tax" to find sources to help confirm this. Keep in mind that while the state overall does not impose sales tax, this does not mean the city and/or county governments won't impose sales tax. Unfortunately it's hard to escape taxes and sales tax is just one of those inevitable things.True. As mentioned in problem 3, local governments (city and/or county) tend to impose taxes of their own on top of state sales taxes. Sales taxes fund state programs while local taxes fund local programs. Though some local government programs will use state or federal dollars.

Problem 1

Domain:   [-3, 5)

Range:    (-4, 3]

The domain is the set of allowed x inputs, while the range is the set of allowed y outputs. For problems like this, we just list the smallest and largest values possible. In this question, the left most point happens when x = -3 and the right most point is when x = 5, but we don't include this value due to the open hole. So that's why we have a curved parenthesis as part of the domain here. The range is a similar story, but we look at the y values instead.

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

Problem 2

Domain:   [-2, 4)

Range:    [-2, 5)

We aren't including any of the endpoints due to the open holes. Be sure not to mix this notation up with ordered pair notation.

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

Problem 3

Domain:  [1, 4]

Range:   [-4, -1]

We include each endpoint because of the filled in circles, so that's why we use square brackets here.

Chef bought 3 3/4 kilograms of apples 7 1/4 kilograms of pears and 10 1/8 kilograms of oranges. How many kilograms of fruit is a chef choose the best estimate


Answers

Answer: 21 1/8 kilogram

Step-by-step explanation:

From the question, we are informed that Chef bought 3 3/4 kilograms of apples 7 1/4 kilograms of pears and 10 1/8 kilograms of oranges. The total kilogram of fruits bought would be:

= 3 3/4 + 7 1/4 + 10 1/8

Note that the Lowest Common Multiple is 8.

= 3 6/8 + 7 2/8 + 10 1/8

= 20 9/8

= 21 1/8 kilogram

Answers

Answer:

12 candy bars.

Step-by-step explanation:

Answer:

72 more candy bars

Step-by-step explanation:

Divide 20.88 by 1.74 to see how many times 1.74 can go into 20.88. You get 12. If 6 candy bars in total cost 1.74, you multiply 12 by 6 because you have 12 groups of 1.74. 12 times 6 is 72. So Bobby can buy 72 more candy bars.

By what factor does the output value increase as each input value increases by 1​

Answers

Given:

The table of values of an exponential function.

To find:

The factor by which the output value increase as each input value increases by 1​.

Solution:

The general exponential growth function is

[tex]f(x)=ab^x[/tex]          ...(i)

where, a is initial value and b is growth factor.

From the given table it is clear that the function passes through (0,3). So, put x=0 and f(x)=3 in (i).

[tex]3=ab^0[/tex]

[tex]3=a(1)[/tex]

[tex]3=a[/tex]

From the given table it is clear that the function passes through (2,12). So, put a=3, x=2 and f(x)=12 in (i).

[tex]12=3b^2[/tex]

Divide both sides by 3.

[tex]4=b^2[/tex]

Taking square root on both sides, we get

[tex]\pm \sqrt{4}=b[/tex]

[tex]\pm 2=b[/tex]

Growth factor cannot be negative. So, b=2.

Therefore, the output value increase by factor 2 as each input value increases by 1​.

The plan for a city park shows that the park is a quadrilateral with straight paths along the diagonals. For what values of the variables is the park a parallelogram? In this case, what are the lengths of the paths?

Answers

Answer:

x = 10, y = 15RT = 210 m, US = 396 m

Step-by-step explanation:

Diagonals of parallelogram bisect each other;

UV = VS and RV = VT

Substitute values:

11y + 33 = 14y - 12 ⇒ 14y - 11y = 33+12 ⇒ 3y = 45 ⇒ y = 15

US = 2(11*15+33) = 396 m

3x + 5y = 6x + 3y ⇒ 6x - 3x = 5y - 3y ⇒ 3x = 2y ⇒ 3x = 30 ⇒ x = 10

RT = 2(3*10 + 5*15) = 210 m

These marbles are placed in a bag and two of them are randomly drawn what is the probability of drawing two yellow marbles if the first one is not placed back into the bag before the second draw

Answers

Answer:

It is 1/45

Step-by-step explanation:

The probability of drawing two yellow marbles=4/45.

It is given that Total number of marbles=10 ,number of yellow marble is 2, number of pink marble is 3 and number of blue marble is 5.

To find the probability of drawing two yellow marbles if the first one is not placed back into the bag before the second draw.

What is probability?

The extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases possible.

The probability of drawing first yellow marble=2/10=1/5

When first yellow marble is not placed back into the bag before the second draw.

Then, number of remaining  yellow marble=1

Total number of marbles=9

The probability of drawing second yellow marble =4/9

Now, the probability of drawing two yellow marbles =1/5*4/9=4/45

Hence, the probability of drawing two yellow marbles=4/45

(b) How many times would all the three events happen together again between midnight and one
o'clock?

Answers

Answer:

It will occur zero times between midnight and one o'clock.

Step-by-step explanation:

Least Common Multiple (LCM)

Three events keep James from sleeping: his clock ticking every 20 seconds, a tap dripping every 15 seconds, and his dog snoring every 27 seconds.

All three events happened together at midnight. They will happen together again the first time the numbers 20, 15, and 27 have a common multiple. This is the LCM.

List the prime factors of each number:

20: 2,2,5

15: 3,5

27: 3,3,3

Now multiply all the factors the maximum number of times they appear:

LCM=2*2*3*3*3*5=540

(a) All the events will happen together again after 540 minutes.

(b) Since 540 minutes = 9 hours, this event won't happen again until 9 am. Thus, it will occur zero times between midnight and one o'clock.
