Answer:

SinB = Sin30 = 0.5

Step-by-step explanation:

Ok lets use sine rule

a/SinA = b/SinB = c/SinC

a/Sin60 = b/SinB = 12/Sin90

b/Sin30 = 12/Sin90

b = (12 × Sin30) ÷ Sin90

b = (12 × 0.5) ÷ 1

b = 6cm

SinB = Sin30 = 0.5

Answer:Therefore the two numbers are -20 and -40

Step-by-step explanation:

Let the two numbers be a and b,

It is given that their sum is 60, so a + b = -60,

It is also given that their difference is 20, so a - b = 20,

Since we don’t know yet which one out of a and b is greater, assume any one of them to be larger than the other (a in my case),

Add the above two equations, you get,

2a = -40 or a = -20,

Substitute this value of a in any of the formed equations,

a + b = -60,

-20 + b = -60 or b = -40,

Let the two numbers be a and b,

It is given that their sum is 60, so a + b = -60,

It is also given that their difference is 20, so a - b = 20,

Since we don’t know yet which one out of a and b is greater, assume any one of them to be larger than the other (a in my case),

Add the above two equations, you get,

2a = -40 or a = -20,

Substitute this value of a in any of the formed equations,

a + b = -60,

-20 + b = -60 or b = -40,

Therefore the two numbers are -20 and -40

The smaller number is 17, and the larger number is 43. The two equations formed from the given information are solved simultaneously to find these numbers.

To solve this problem, we need to set up two equations based on the given information. Let's denote the smaller number by s and the larger number by l.

The sum of the two numbers is 60: s + l = 60.

If twice the smaller number is subtracted from the large number, the result is 9: l - 2s = 9.

We can solve these equations simultaneously. First, rearrange the second equation to express l in terms of s: l = 2s + 9. Next, substitute this expression into the first equation:

s + (2s + 9) = 60

3s + 9 = 60

3s = 51

s = 17

Now we have found the smaller number is 17. To find the larger number, we substitute s back into the equation for l:

l = 2(17) + 9

l = 34 + 9

l = 43

So the two numbers are 17 and 43

It will take [tex]20\frac{5}{6}[/tex] minutes to fill a 50 gallon tub.

Step-by-step explanation:

Time taken to fill 3 gallons bucket = [tex]1\frac{1}{4}=\frac{5}{4}\ minutes[/tex]

We have to find time required to fill 50 gallons tub.

3 gallons = [tex]\frac{5}{4}\ minutes[/tex]

1 gallon = [tex]\frac{5}{4}*\frac{1}{3}\ minutes[/tex]

1 gallon = [tex]\frac{5}{12}\ minutes[/tex]

To find the time required for 50 gallons;

50 gallons = 50 * Time per gallon

50 gallons = [tex]50*\frac{5}{12}[/tex]

50 gallons = [tex]\frac{250}{12}[/tex] = [tex]\frac{125}{6}[/tex]

50 gallons = [tex]20\frac{5}{6}\ minutes[/tex]

It will take [tex]20\frac{5}{6}[/tex] minutes to fill a 50 gallon tub.

Final answer:

It takes approximately 20.83 minutes to fill a 50 gallon tub if it takes 1 1/4 minutes to fill a 3 gallon bucket, considering a constant rate of filling.

Explanation:

The question asks us to determine how long it will take to fill a 50 gallon tub if it takes 1 1/4 minutes to fill a 3 gallon bucket. To solve this, we can set up a proportion since the rates of gallons per minute will be the same for both the bucket and the tub.

First, let's convert the time from minutes to seconds to match the unit for seconds provided in the example. There are 60 seconds in a minute, so 1 1/4 minutes is equal to 75 seconds.

Now, we know it takes 75 seconds to fill 3 gallons. Let's calculate the number of seconds it takes to fill 1 gallon, and then we will use that rate to find out how many seconds it will take to fill 50 gallons.

We divide 75 seconds by 3 gallons, to get 25 seconds per gallon. Then we multiply this rate by 50 gallons to find the total time needed to fill the tub:

25 seconds/gallon × 50 gallons = 1250 seconds.

Finally, to convert seconds back to minutes, we divide 1250 seconds by 60:

1250 seconds ÷ 60 seconds/minute = 20 5/6 minutes or approximately 20.83 minutes.

So, it takes approximately 20.83 minutes to fill a 50 gallon tub at the given rate.

To evaluate the expression[tex]\(3x^3 - \frac{2}{y^6}x^2y^2 + xy\) for \(x = \frac{2}{3}\) and \(y = \frac{1}{2}\),[/tex]let's substitute these values into the expression:

[tex]\[3\left(\frac{2}{3}\right)^3 - \frac{2}{{\left(\frac{1}{2}\right)}^6}\left(\frac{2}{3}\right)^2\left(\frac{1}{2}\right)^2 + \frac{2}{3} \times \frac{1}{2}\][/tex]

Let's simplify this step by step.

1. [tex]\(3\left(\frac{2}{3}\right)^3 = 3 \times \frac{8}{27} = \frac{24}{27} = \frac{8}{9}\)[/tex]

2.  [tex]\(- \frac{2}{{\left(\frac{1}{2}\right)}^6}\left(\frac{2}{3}\right)^2\left(\frac{1}{2}\right)^2 = - 2 \times 2^6 \times \frac{1}{3^2} \times \frac{1}{2^2} = - 2 \times 64 \times \frac{1}{9} \times \frac{1}{4} = - \frac{128}{9}\)[/tex]

3   .[tex]\(\frac{2}{3} \times \frac{1}{2} = \frac{1}{3}\)[/tex]

Now, let's add these results together:

[tex]\[\frac{8}{9} - \frac{128}{9} + \frac{1}{3} = \frac{8 - 128 + 3}{9} = \frac{-117}{9} = -\frac{13}{3}\][/tex]

So, [tex]\(3x^3 - \frac{2}{y^6}x^2y^2 + xy\) evaluated at \(x = \frac{2}{3}\) and \(y = \frac{1}{2}\) is \(-\frac{13}{3}\).[/tex]

Answer:

1. x = 12

2. 3∛4 feet.

Step-by-step explanation:

1. We are given the equation of x as [tex]\sqrt{x - 3} + x = 9[/tex] and we have to find the extraneous solution of the equation.

Now, [tex]\sqrt{x - 3} + x = 9[/tex] ............. (1)

⇒ [tex]\sqrt{x - 3} = 9 - x[/tex]

Squaring both sides we get,

⇒ x - 3 = 81 - 18x + x²

⇒ x² - 19x + 84 = 0

⇒ x² - 12x - 7x + 84 = 0

⇒ (x - 12)(x - 7) = 0

⇒ x = 12 or 7.

Now, putting x = 12 in the equation (1) we get,

[tex]\sqrt{12 - 3} + 12 \neq 9[/tex]

Again, putting x = 7 in the equation (1) we get,

[tex]\sqrt{7 - 3} + 7 = 9[/tex]

Therefore, x = 12 is an extraneous solution of this equation. (Answer)

[tex]\( f(2) = \ln \left( \frac{14}{3} \right) \)[/tex]. You can calculate this value to get a numerical result.

To find the particular solution [tex]\( y = f(x) \)[/tex] to the given differential equation [tex]\( \frac{dy}{dx} = \frac{x^2 + 1}{e^y} \)[/tex] with the initial condition [tex]\( f(1) = 0 \)[/tex] and then evaluate [tex]\( f(2) \),[/tex] we can follow these steps:

1. Separate variables:

[tex]\[ e^y dy = (x^2 + 1) dx \][/tex]

2. Integrate both sides:

[tex]\[ \int e^y dy = \int (x^2 + 1) dx \][/tex]

[tex]\[ e^y = \frac{1}{3} x^3 + x + C \][/tex]

3. Apply the initial condition [tex]\( f(1) = 0 \):[/tex]

[tex]\[ e^0 = \frac{1}{3} (1)^3 + 1 + C \][/tex]

[tex]\[ 1 = \frac{1}{3} + 1 + C \][/tex]

[tex]\[ C = \frac{2}{3} \][/tex]

So, the particular solution is:

[tex]\[ e^y = \frac{1}{3} x^3 + x + \frac{2}{3} \][/tex]

4. Solve for  y :

[tex]\[ y = \ln \left( \frac{1}{3} x^3 + x + \frac{2}{3} \right) \][/tex]

Now, we need to find f(2), which means finding the value of y when  x = 2:

[tex]\[ y = \ln \left( \frac{1}{3} (2)^3 + 2 + \frac{2}{3} \right) \][/tex]

[tex]\[ y = \ln \left( \frac{8}{3} + 2 + \frac{2}{3} \right) \][/tex]

[tex]\[ y = \ln \left( \frac{14}{3} \right) \][/tex]

Final answer:

By setting up an equation based on the given information that Jim is 2 years older than 3 times Tommy's age and their combined ages are 18, we find that Tommy is 4 years old and Jim is 14 years old.

Explanation:

The question is about finding the ages of Jim and his younger brother Tommy given that Jim is 2 years older than 3 times Tommy's age and together their ages add up to 18. Let's denote Tommy's age as T years. Therefore, Jim's age would be 3T + 2 years. According to the problem, if we add both ages, the sum is 18. So, we can set up the following equation to find their ages:

T + (3T + 2) = 18

Simplifying this equation gives:

4T + 2 = 18

4T = 16

T = 4

Thus, Tommy is 4 years old. To find Jim's age, we substitute Tommy's age back into the equation for Jim's age:

Jim's age = 3(4) + 2 = 12 + 2 = 14

Therefore, Tommy is 4 years old, and Jim is 14 years old.

The function rule that relates y (circumference) to x (diameter) is y = π x [pi × x]

Since x represents the diameter of the circle and y represents the circumference.

For a circle with radius r, circumference of the circle (y)equals,

y = 2πr ................................(1)

Diameter of a circle is twice the radius of the circle.

Assuming x as the diameter

[tex]x = 2\times r = 2r[/tex] ...........................(2)

Substituting (2) in (1), we get

y = π(2r) = πx ..............................................(3)

A function rule is an equation that determines the relation between a dependent variable and an independent variable. The relation between diameter of a circle and its circumference can be given as

Circumference = Pi × Diameter of circle

y = π × x
