Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

tanx = [tex]\frac{1}{cotx}[/tex]

Consider the left side

[tex]\frac{cotA-1}{cotA+1}[/tex] ← divide terms on numerator/denominator by cotA

= [tex]\frac{\frac{cotA}{cotA}-\frac{1}{cotA} }{\frac{cotA}{cotA}+\frac{1}{cotA} }[/tex]

= [tex]\frac{1-tanA}{1+tanA}[/tex]

= right side , thus proven

Answer:

Profit = price charged  -  cost of goods

$10  =  Price - 30.00

$40 = Price of one box

So, they have to charge $40 per box. Since there are 50 bars in each box, the price per bar has to be:

$40.00/50 bars = $0.80 per bar

You can check this....

0.80  x  50 bars  = $40.00 <<< this is the total income from the sale of one box.

since each box costs $30.00, they've made $10.00 on each box.

Answer:

(0,5) and (10,0)

Step-by-step explanation:

The equation of the straight line is given by 2x + 4y = 20 .......... (1)

Now, point (0,5) satisfies the equation (1) as putting x = 0, we will get y = 5.

Now, point (0,10) does not satisfy the equation (1) as putiing x = 0, we get y = 5 ≠ 10

Again, point (1,2) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 2

Now, point (1,4) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 4

Again, point (5,0) does not satisfy the equation (1) as putiing y = 0, we get x = 10 ≠ 5

Finally, point (10,0) satisfies the equation (1) as putiing y = 0, we get x = 10 .

Therefore, only points (0,5) and (10,0) are on the graph of the line 2x + 4y = 20 (Answer)

Step-by-step explanation:

If angle x is a right angle, meaning 90 degrees, and the right angle is dissected into two angles with one of them being 50 degrees that leaves 40 degrees left to complete the 90 degree right angle

The answer you are looking for is .

To find this answer, you first make 75% into a decimal. To do so, simply divide 75 by 100 to get 0.75. Finally, you multiply 0.75 to 25. This will give you 1875 which you add a decimal point between the 8 and the 7, because .75 has 2 digits behind the decimal (as should the answer. Thus getting 18.75 as an answer. Here's an image to show the multiplication of 0.75 and 25.

................b = 17...............

Answer:

b) 272/p

Step-by-step explanation:

1/4(px-16)=64

1. multiply 4 on both side to cancel out 1/4

(px-16)=256

2. move -16 to the otherside (making it postive)

px=16+256

px=272

3. divide by p on both sides

x=272/p

Answer:

£39

Step-by-step explanation:

Given data

The sharing formula is

5:3

Let June get £x

Buck gets £26 more than june

Buck = x+26

Applying the part to part ratio method

5/3= x+26/x

cross multiply

3(x+26)= 5x

3x+78= 5x

78= 5x-3x

78= 2x

x= 78/2

x= £39

Hence June get £39

Answer:

a = 11

b = 14

c = 28

Step-by-step explanation:

a+b+c = 53

b-3 = a

c = 2b

substitute for a and c

(b-3)+b+(2b) = 53

reduce

4b-3 = 53

add 3 to each side

4b = 56

divide both sides by 4

b = 14

a = 14-2 = 11

c = 2(14) = 28

Answer:

a) Area of sector TRV = [tex] 42.4\: units^2 [/tex]

b) [tex] 0.8\: units[/tex]

Step-by-step explanation:

a)

In [tex] \odot R[/tex], TW is diameter.

Therefore,

[tex] m\widehat {TVW} = 180\degree [/tex]

[tex] \because m\widehat {TV} +m\widehat {VW} =m\widehat {TVW} [/tex]

[tex] \therefore m\widehat {TV} +120\degree =180\degree [/tex]

[tex] \therefore m\widehat {TV} =180\degree - 120\degree [/tex]

[tex] \therefore m\widehat {TV} = 60\degree [/tex]

[tex] \because m\angle TRV=m\widehat{TV} [/tex]

(Measure of central angle is equal to the measure of its corresponding arc)

[tex] \therefore m\angle TRV\:(\theta) =60\degree [/tex]

Radius (r) = RW = 9 units

Area of sector TRV

[tex] =\frac{\theta}{360\degree}\times \pi r^2 [/tex]

[tex] =\frac{60\degree}{360\degree} \times 3.14\times 9^2 [/tex]

[tex] =\frac{1}{6} \times 3.14\times 81 [/tex]

[tex] =\frac{1}{6} \times 254.34 [/tex]

[tex] =42.39\: units^2 [/tex]

Area of sector TRV[tex] =42.4\:units^2 [/tex]

b)

Length of [tex] \widehat{VW} [/tex]

[tex] =\frac{120\degree }{360\degree} \times 2\pi r [/tex]

[tex] =\frac{2}{3} \times 3.14\times 9 [/tex]

[tex] =2 \times 3.14\times 3 [/tex]

Length of [tex] \widehat{VW} [/tex] [tex] = 18.84\: units [/tex]

[tex] \overline{TW} =2*RW =2*9 = 18\: units[/tex]

[tex] \widehat{VW}- \overline{TW}= 18.84-18=0.84\: units[/tex]

[tex] \widehat{VW}- \overline{TW}= 0.8\: units[/tex]

Answer:Theres no table please edit and put a table.

Answer:

30 + 3n

Step-by-step explanation:

33 , 36 , 39 .......

This is an arithmetic series

First term = 33

Common difference (d) = Second term -  first term

                                        = 36 - 33 = 3

Nth term = a + (n -1)* d

              =  33 + ( n-1) * 3

              = 33 + n*3 - 1*3

              = 33 + 3n - 3

              = 33 - 3 + 3n

               = 30 + 3n

Out of 200 customers, the probability of a customer not ordering either donuts or cinnamon rolls is 0.2 or 20%.

Use the concept of probability defined as:

For the occurrence of an event, it is a ratio of the number of favorable outcomes to the number of total outcomes.

Given that,

Time frame: 6 am to 10 am

Total number of customers: 200

Number of customers who ordered donuts: 140

Number of customers who ordered cinnamon rolls: 100

Number of customers who ordered both donuts and cinnamon rolls: 80

To find the probability of a customer ordering neither donuts nor cinnamon rolls:

Subtract the probability of a customer ordering either donuts or cinnamon rolls or both from 1.

Now calculate:

Probability of ordering donuts:

140 out of 200 customers ordered donuts,

The probability of ordering donuts is,

140/200 = 0.7.

Probability of ordering cinnamon rolls:

100 out of 200 customers ordered cinnamon rolls,

The probability of ordering cinnamon rolls is,

100/200 = 0.5.

Probability of ordering both donuts and cinnamon rolls:

80 out of 200 customers ordered both,

The probability of ordering both is,

80/200 = 0.4.

Now, to find the probability of a customer ordering neither donuts nor cinnamon rolls,

Subtract the probability of ordering either or both from 1:

P(no donuts & no cinnamon rolls) = [tex]1 - P( \text{donuts}) - P(\text{cinnamon rolls}) + P(\text{donuts & cinnamon rolls})[/tex]

[tex]\text{P(no donuts & no cinnamon rolls)}= 1 - 0.7 - 0.5 + 0.4[/tex]

[tex]\text{P(no donuts & no cinnamon rolls)} = 0.2[/tex]

Hence,

The probability of a customer not ordering either donuts or cinnamon rolls is 0.2 or 20%.
