Answer:

x = π n + cot^(-1)(22/29) for n element Z

Step-by-step explanation:

Solve for x:

cos(x) = (22 sin(x))/29

Divide both sides by sin(x):

cot(x) = 22/29

Take the inverse cotangent of both sides:

Answer: x = π n + cot^(-1)(22/29) for n element Z

Answer:

This function is True

Step-by-step explanation:

Since there is one value of  y  for every value of  x .

Answer:

x = 114°

y = 27

Step-by-step explanation:

To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.

To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.

Answer:

x= 114,

y= 27

Step-by-step explanation:

x= 180 - 66 = 114

6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

Answer:

There are 36 total possible outcomes.

Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.

Rolling a sum of 9, there are 4 possibilities, which is a better chance.

Rolling a sum less than 5, there is 6 possibilities, which is a better chance.

Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.

Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.

Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

The answers would be:

Rolling a sum of 9,

Rolling a sum less than 5

Rolling greater than 5 but less than 7

Step-by-step explanation:

[tex]3x-1/9(27)=18\\3x-3=18\\3x=18+3\\3x=21\\3x/3=21/3\\x=7[/tex]

Answer:

x =7

Step-by-step explanation:

3x-1/9y=18

Add 1/9 y to each side

3x-1/9y + 1/9 y=18+ 1/9 y

3x = 18 + 1/9 y

Divide by 3

3x/3 = 18/3 + 1/9y *1/3

x = 6 + 1/27 y

Let y = 27

x= 6+ 1/27 * 27

x = 6+1

x = 7

Step-by-step explanation:

James' age = J

a) Annie is 3 years older than James so,

Annies age = 3 +J

b) Sum of their ages is 18 so,

Annies age + James' age = 18

= 3 + J + J = 18

2J = 18-3

J = 15/2 = 7.5

c) Annies age = 3 + J = 3 + 7.5

= 10.5 years

Answer:

This is really weird. None of them seem to be right.

For the first one, it says that -7.5 is greater than or equal to -6.4, which is not true. -7.5 is less than -6.4. The next one is the only one that makes a true comparison, but I don't agree with the "or equal to" part. -7/8 cannot be equal to 7/8. The next one is false, -4 is greater than -8. Finally, the last one is incorrect as well because -4.2 is less than -3.6.

However, if I had to choose one, I'd choose the second option. It's the closest to being correct.

Step-by-step explanation:

Step 1: Find # of gender toys

80(0.4) = 32 toys for boys

80 - 32 = 48 toys for girls

Step 2: Find % made

32(0.5) = 16 toys made (boys)

48(0.5) = 24 toys made (girls)

Step 3: Find the difference

24 - 16 = 8

Answer:

The answer is 166/21, or 7 19/21

Step-by-step explanation:

First, you would set up the equation, which is:

13 1/7 - 5 5/21

Next, you would turn them into an improper fraction, which is:

92/7 - 110/21

Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:

276/21 - 110/21

Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.

Answer:

7 19/21

Step-by-step explanation:

13 1/7 - 5 5/21

Get a common denominator

13 1/7*3/3 - 5 5/21

13 3/21 - 5 5/21

We need to borrow 1 from the 13 in the form of 21/21

12 +21/21 + 3/21   - 5 5/21

12 24/21 - 5 5/21

7 19/21

Answer:

x=-2

y=-10

Step-by-step explanation:

x+y=-12

x-y=8

x=y+8

(y+8)+y=-12

2y+8=-12

2y=-20

y=-10

x+10=8

x=-2

Answer:

[tex]x = - 2 \\ y = - 10[/tex]

Step-by-step explanation:

[tex]x + y = - 12 \\ x - y = 8[/tex]

[tex]x + y + (x - y) = - 12 + 8 \\ x + y + x - y = - 4 \\ 2x = - 4 \\ \frac{2x}{2} = \frac{ - 4}{2} \\ x = - 2[/tex]

[tex]x + y = - 12 \\ - 2 + y = - 12 \\ y = - 12 + 2 \\ y = - 10[/tex]

Answer:

D

Step-by-step explanation:

[tex]P(1+r\%)^t[/tex]

[tex]700 \times (1+0.8\%)^5[/tex]

[tex]700 \times (1+0.8/100)^5[/tex]

[tex]700 \times (1+0.008)^5[/tex]

[tex]700 \times (1.008)^5[/tex]

The value expresses the population five years later is (700)(1.008)^5.

We have given that in 1997 the population of a small town was 700.

The annual rate of increase is about 0.8%.

We have to find the population for 5 years

[tex]F=P(1+r)^t\\\\[/tex]

Here p=700

r=0.8/100=0.008

t=5

Use the above value in the formula so we get,

[tex]F=700(1+0.008)^5[/tex]

[tex]F=700(1.008)^5[/tex]

Therefore option D is correct.

Perimeter = 86.4 (m)

Step-by-step explanation:

A square (with side x) has an area of 466.56 (m^2)

=> x^2 = 466.56

=> x = sqrt(466.56) = 21.6

=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Answer:

The probability under the given conditions is found:

P(7) = 0.079

Step-by-step explanation:

Let x be the number of adults who believe in reincarnation.

Adults randomly selected = 8

percentage of adult believe in reincarnation = 40% = 0.4

x follows binomial distribution:

P(x) =  [tex]\left(\begin{array}{ccc}n\\x\end{array}\right) (p)^x(1-p)^{n-x}[/tex]

where

n= total people random people selected = 8,

x = selected for the part = 7,

p = probability given = 0.4

P(7) = [tex]\left(\begin{array}{ccc}8\\7\end{array}\right) (0.4)^7(1-0.4)^{8-7}[/tex]

P(7)= (8)(0.0164)(0.6)

P(7) = 0.07872

Rounding off to 3 decimal positions

P(7) = 0.079

Answer:

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325

Step-by-step explanation:

Given the following ;

Brand 232:

Cost per ounce = 36cent

Brand 880:

Cost per ounce = $2.04 = 204cent

Assume the following :

Number of ounces of 232 brand = x

Number of ounces of 888 brand = y

Total ounces to be made :

x + y = 393 - - - (1)

Total cost of iodine :

Brand 232 = 36x

Brand 888 = 204y

36x + 204y = 25572 - - - - (2)

From (1)

x = 393 - y - - - - (3)

Substitute (3) into (2)

36(393 - y) + 204y = 25572

14148 - 36y + 204y = 25572

-36y + 204y = 25572 - 14148

168y = 11424

y = 11424 / 168

y = 68

From ; x = 393 - y

y = 68

x = 393 - 68

x = 325

Number of ounces of iodine 888 brand = 68

Number of ounces of iodine 232 brand = 325

Answer:

The amount invested at 9% is $30,000

Step-by-step explanation:

Mardi received an inheritance of $40,000.

Let x be the amount invested at 9%.

So, Amount invested at 10% = 40000-x

Her total annual income from the investments was  $3700.

So, [tex]0.09x+0.1(40000-x)=3700[/tex]

[tex]0.09x+4000-0.1x=3700[/tex]

x=30000

Hence the amount invested at 9% is $30,000
