find the value of x in the below complementary angle 3x(5x+2)​

Answers

Answer:

The value of x is 11

Step-by-step explanation:

Two angles are complementary if the sum of their measures is 90°

Let us use this rule to solve our question

∵ The angle of measure (3x)° and the angle of measure (5x + 2)°

   are complementary angles

→ That means their sum equals 90°

3x + 5x + 2 = 90

→ Add the like terms in the left side

∵ (3x + 5x) + 2 = 90

∴ 8x + 2 = 90

→ Subtract 2 from both sides to move 2 from the left side to the right side

∵ 8x + 2 - 2 = 90 - 2

∴ 8x = 88

→ Divide both sides by 8 to find x

∵ 8x/8 = 88/8

x = 11

The value of x is 11

Can someone help me with the concept of this? We have a worksheet with like 45 questions and I have no clue how to do it. We have to say if it’s similar or not and then, how we know theyre similar, and a similarity statement

Answers

Answer:

So since QRS is ~ another triangle, and they are not exactly similar, I assume that the problem wants you to compare QRS with another angle. QRS is closely congruent to UVW (assuming that you are comparing triangles not angles).

Step-by-step explanation:

All triangles have an angle total of 180 degrees. If you add those two angles together, they have the same sum, and the third anglecan be found by subtracting the total from 180. For example, 95+36 = 131. 180-131=49, which is the third angle for triangle QRS. You can do the same for UVW.

It is important to compare them in order. For instance, Triangle QRS would not be congruent to WVU since they are not in the same order. To compare them in the correct order, compare the angles. Q is about equal to U. R is about equal to V. S is about equal to W since they both have missing angles. Therefore, you can state that triangle QRS is about equal to UVW.

Answer:

  make use of the ways similarity can be shown

Step-by-step explanation:

Similarity of triangles can be shown two (2) ways:

corresponding angles are congruentcorresponding sides are proportional

__

In a worksheet like this, you may see several kinds of problems. The keys will be ...

the parts that you claim are proportional or congruent must be correspondingthe sum of angles in a triangle is 180°.

__

When two angles are given, as here, at least one of them in one triangle must match one in the other triangle.

Here, neither of the measures 35 and 96 matches either of the measures 36 and 95. These triangles cannot be similar.

__

Further discussion on working these problems

If one of the numbers does match, then you need to find the third angle to see if it matches the remaining angle. If two numbers match, the triangles are similar by AA.

Even if you find all three angles match, you need to carefully check any similarity statement to make sure it lists the matching angles in the same order.

For example, suppose both sets of angles in these triangles were 94 and 37. ∆QRS lists these in the order 94° angle, 37° angle. Then the similarity statement would have to list the other triangle's vertices in the same order: ∆UVW. A typical problem might claim similarity to ∆VUW, just to see if you're paying attention to detail. That claim would be false.

__

For comparing side lengths, it can work well to compare them smallest-to-largest, or in some other order you find easy to remember.

It has been observed that a large percentage of professional hockey players have birthdays in the first part of the year. It has been suggested that this is due to the cut-off dates for participation in the youth leagues - those born in the earlier months are older than their peers and this advantage is amplified over the years via more opportunities to train and be coached. Of the 511 professional hockey players in a season, 159 of them were born in January, February, or March.

Requried:
a. Assume that 25% of birthdays from the general population occur in January, February, or March (these actually contain 24.7% of the days of the year). In random samples of 508 people, what is the mean number of those with a birthday in January, February, or March?
b. What is the standard deviation?
c. Now, 158 of the 508 professional hockey players were born in the first three months of the year. With respect to the mean and standard deviation found in parts (a) and (b) what is the z-score for 158?
d. If the men in the professional hockey league were randomly selected from the general population, would 158players out of 508 be an unusual number of men born in the first 3 months of the year?

e. Which of the following is an acceptable sentence to explain this situation?

1. If the men in the professional hockey league were selected randomly from the general population, this would be an unusual collection of birth dates.
2. There is good reason to believe that a significantly larger than expected proportion of professional hockey league players are born in the first three months of the year.
3.This could be a result of the random variation of birth dates within a sample. However, it would be pretty unlikely to happen by chance.
4. All of these are valid statements.

Answers

Answer:

a

[tex]\mu  =  127[/tex]

b

[tex]\sigma  =  9.76[/tex]  

c

[tex]z-score  =  3.18 [/tex]

d

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158  is  greater than  3( Note :the probability of  z-score = 3 is  97%)

e

The correct option is  option 3

Step-by-step explanation:

From the question we are told that

   The population proportion is  p =  0.25

   The sample size is  n =  508

   

Generally the mean is  mathematically represented as  

     [tex]\mu  =  np[/tex]

=>   [tex]\mu  =  508 * 0.25[/tex]

=>   [tex]\mu  =  127[/tex]

Generally the standard deviation is mathematically represented as

     [tex]\sigma  =  \sqrt{ np (1-p)}[/tex]

=>   [tex]\sigma  =  \sqrt{ 508 * 0.25 (1-0.25)}[/tex]    

=>    [tex]\sigma  =  9.76[/tex]  

Generally the z-score of  158 is mathematically represented as

    [tex]z-score  =  \frac{158 - 127}{9.76}[/tex]

=>  [tex]z-score  =  \frac{158 - 127}{9.76}[/tex]

=>  [tex]z-score  =  3.18 [/tex]

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158  is  greater than  3( Note :the probability of  z-score = 3 is  97%)

What this means is that the almost the whole  professional hockey league player are born in the first month which is unusual

Bags of flour at a local grocery store have a mean weight of 83 ounces with a standard deviation of 2 ounces. Which weight represents the 65th percentile?
A.82.2 ounces
B.82.5 ounces
C.83.5 ounces
D.83.8 ounces

Answers

Answer:

D.83.8 ounces

Step-by-step explanation:

The z score for 65th percentile = 0.385

Mean weight of 83 ounces with a standard deviation of 2 ounces

The formula for calculating a z-score is z = (x-μ)/σ

where x is the raw score

μ is the population mean

σ is the population standard deviation

x = ??

Hence:

0.385 = (x - 83)/2

Cross Multiply

0.385 × 2 = x - 83

0.77 = x - 83

x = 83 + 0.77

x = 83.77 ounces

Approximately = 83.8 ounces

Answer:

D.83.8 ounces

Step-by-step explanation:

The z score for 65th percentile = 0.385

Mean weight of 83 ounces with a standard deviation of 2 ounces

The formula for calculating a z-score is z = (x-μ)/σ

where x is the raw score

μ is the population mean

σ is the population standard deviation

x = ??

Hence:

0.385 = (x - 83)/2

Cross Multiply

0.385 × 2 = x - 83

0.77 = x - 83

x = 83 + 0.77

x = 83.77 ounces

Approximately = 83.8 ounces

an open tank has tge shape of circular cone. the tank is 8feet across the top and 6 feet high. watwr is pumped through the buttom of the tank. how much work is done to fill the tank from a depth of 4 feet to a depth of 6 feet? water weighs 62.4 pounds per cubic foot

Answers

Answer:

[tex]W=22652.98ft-lb[/tex]

Step-by-step explanation:

We are given that

Height of tank=6feet

Diameter of tank=8 feet

Radius of cone,r=d/2=8/2=4 feet

Let  a layer of thickness dy at distance yr from the bottom at origin

y=6 feet

Using similar triangle property

[tex]\frac{r}{y}=\frac{4}{6}=\frac{2}{3}[/tex]

[tex]r=\frac{2}{3}y[/tex]

Weight of water=62.4 pounds per cubic foot

Now,

Weight of layer=[tex]62.4\times \pi r^2 h=62.4(\frac{4}{9}\pi y^2 dy[/tex]

Now, work done to fill the tank from a depth of 4 feet  to a depth of  6 feet is given by

[tex]W=\int_{a}^{b}62.4\times \frac{4}{9}\pi y^2(y) dy=\int_{4}^{6}62.4\times \frac{4}{9}\pi y^3 dy[/tex]

[tex]W=\frac{62.4\times 4\pi}{9}[\frac{y^4}{4}]^{6}_{4}[/tex]

[tex]W=\frac{249.6\pi}{36}(6^4-4^4)[/tex]

[tex]W=22652.98ft-lb[/tex]

Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlted which raw materials wore produced

Answers

Answer: D . Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlled which raw materials wore produced

Step-by-step explanation:

In the colonial era of the United States, the British who were in charge then engaged in an Economic policy called Mercantilism. This was a system where they limited imports into Britain but encouraged exports from Britain so that they would maintain a favorable balance of trade.

A key part of this system was having colonies that goods could be exported to and that raw materials could be acquired from at a cheap rate.

Southern colonies like Georgia fulfilled this mandate more than the rest as they would ship raw materials to Britain and buy manufactured goods from them with Britain controlling which raw materials Georgians produced.
