The total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

W=1/n

A construction company is building a wall. The company can build 30 cm of the wall per minute. In 40 minutes the total cm of wall build by company is,

n=40/30

n=1200 cm

n=12 m

After 40 minutes, three fourth of the wall is completed, which is equal to the 12 meters. Thus, the total meter of the wall is,

(3/4)x=12

x=(12x4)/3

x=16 m

Thus, the total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.

Answer:

M = 4.33885225095

Step-by-step explanation:

Area of the square ABFE = 10² = 100

M = 100 - (2P + Q)

Let’s calculate 2P + Q :

The area 2P + Q = area ΔABC + area of sector ACE + area of sector BCF

Note :

ΔABC is an equilateral triangle

m∠CBF = m∠CAE = 30°

area ΔABC  = (CG × AB)÷2 = (8.660254037844×10)÷2 = 43.30127018922

CG = √(10^2 - 5^2)=8.660254037844  (Pythagorean theorem)

area of sector BCF = area ΔACE = 100π ÷ 12 = (8.333333333333)π

then

Area 2P + Q = area  ΔABC + area sector ACE + area sector BCF

                      = 43.30127018922+(100÷12)π+(100÷12)π

                      = 43.30127018922+ (8.333333333333)π + (8.333333333333)π

                      = 95.66114774905

Conclusion:

M = 100 - (2P + Q) = 100-95.66114774905 = 4.33885225095

If manny paid $114.03 for the items purchased , then he paid the correct amount .

The first step is to determine the total cost of all the items purchased.

Total cost = $32.65 + (3 x $14.89) + $39.99 = $117.02.

Now, determine the cost after the promotional sale: (100 - 10%) x $117.02 = $105.32

The last step is to determine the total cost after tax: (1.08) x 105.32 = $114.03

Step-by-step explanation: right triangles need two equal angles and one different.

The expression that represents the volume, in cubic units, of the shaded region of the composite figure is: A. One-half(14)(10)(8) – π(2.52)(8).

Given:

Base side length=14 and 10 units

Height=8 units

Diameter=5 units

Hence:

Expression= 1-( half 14)(10)(8) - π(2.52)(8)

Expression=1-(7) (10)(8) - π(2.52)(8)

Expression=1- (560)- 63.33

Expression=-559-63.33

Expression=-622.33

Therefore the expression that represents the volume, in cubic units, of the shaded region of the composite figure is: A. One-half(14)(10)(8) – π(2.52)(8).

The equation cos (α - β) × cos (α + β) ≠ cos² α - cos² β. Then the given equation is incorrect.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

The equation is given below.

cos (α - β) × cos (α + β) = cos² α - cos² β

Then show whether the equation is correct or incorrect.

Taking the left-hand side, then we have

[tex]\cos(\alpha-\beta)*\cos(\alpha +\beta) = (\cos \alpha \cos\beta + \sin \alpha \sin \beta ) (\cos \alpha \cos\beta - \sin\alpha \sin\beta )\\\\\cos(\alpha-\beta)*\cos(\alpha +\beta) = \cos ^2 \alpha \cos ^2\beta - \sin ^2 \alpha \sin ^2\beta[/tex]

The left-hand side does not equal to the right-hand side.

Express as fraction

x/153 = 4/3

Multiply both sides by 153

x = 204

The statement given by Mai to principal is wrong because of it using the word "exactly" in her statement.

We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.

Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.

Thus, the sample should be taken out such that it includes data of the population as much  as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).

So, in this case, Mai did sampling(sample of 30 students was selected) instead of working on entire population (all students of her school).

In her sample, she found that 27 out of 30 students think its a good idea to start and end the school day an hour later than usual.

So, from sample, 90% of those 30 students think  it’s a good idea to start and end the school day an hour later than usual.

And yes, we can use this data to approximate or predict about the percentage of students who think  it’s a good idea to start and end the school day an hour later than usual.

But we cannot surely say that it will be exactly 90%.

The only statement we can give about the population is:

Almost (or such unsure wordings) 90% of all of the students in the school think it’s a good idea to start and end the school day an hour later than usual!

Thus, the statement given by Mai to principal is wrong because of it using the word "exactly" in her statement.
