Answer:

238°

Step-by-step explanation:

In a cyclic quadrilateral, the pair of opposite angles add up to 180 degrees.

So, the angle "21x - 2" and the angle "38x + 5"  add up to 180.

So, we can write an equation and solve for x first:

[tex]21x-2+38x+5=180\\59x+3=180\\59x=180-3\\59x=177\\x=3[/tex]

x = 3

Now, Arc FGH is DOUBLE of Angle A. Angle A is "38x + 5". We know x, so angle A is:

Angle A = 38x + 5 = 38(3) + 5 = 119

Thus, Arc FGH = 2 * 119 = 238°

Answer:

[tex]\frac{61}{90}[/tex]

Step-by-step explanation:

We require to create 2 equations with the repeated value 7 after the decimal point

Let x = 0.6777777... ← multiply both sides by 10 and 100

10x = 6.777...... → (1)

100x = 67.777..... → (2)

Subtract (1) from (2) thus eliminating the repeating value

90x = 61 ( divide both sides by 60 )

x = [tex]\frac{61}{90}[/tex]

The decimal 0.67 with the repeating 7 can be written as the simplified fraction 2/3.

To rewrite the decimal 0.67 with the repeating 7 as a simplified fraction, we can use the concept of infinite geometric series.

Let x = 0.677777...

Multiply both sides of the equation by 10 to shift the decimal point:

10x = 6.777777...

Now, subtract the original equation from the shifted equation to eliminate the repeating 7s:

10x - x = 6.777777... - 0.677777...

Simplifying, we get:

9x = 6

Divide both sides of the equation by 9 to solve for x:

x = 6/9

The fraction 6/9 can be further simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

x = (6/3) / (9/3)

x = 2/3

Therefore, the decimal 0.67 with the repeating 7 can be written as the simplified fraction 2/3.

Answer:

  9 loaves

Step-by-step explanation:

Judy get 3/4 of the bread, so ...

  (3/4) · 12 loaves = 9 loaves

Final answer:

In order to find out how much bread Kendra gives Judy, we can set up a system of equations.

Explanation:

In order to find out how much bread Kendra gives Judy, we can set up a system of equations based on the information given. Let's say Kendra gives Lynn x loaves of bread. According to the problem, Kendra gives Judy 3 times the amount she gives Lynn, so Judy receives 3x loaves of bread. Together, they receive 12 loaves of bread, so x + 3x = 12. Simplifying the equation, we get 4x = 12. Dividing both sides by 4, we find x = 3. Therefore, Kendra gives Judy 3x = 3(3) = 9 loaves of bread.

Which of the following could be how Julia spends time at the gym?

A  Run for 10 mins and lifting weights for 12 mins.

B  Run for 15 minutes and lift weights for 25 mins.

C  Run for 20 mins and lift weights for 30 mins.

D  Run for 24 mins and lift weights for 48 mins.

E  Run for 30 mins and lift weights for 50 mins.

Answer:

B  Run for 15 minutes and lift weights for 25 mins.

E  Run for 30 mins and lift weights for 50 mins.

Step-by-step explanation:

Given:

Julia Spend s 3 minute for running and weight lifts for 5 mins.

We need to find which choices are correct match for the given data.

Hence we will check each.

A  Run for 10 mins and lifting weights for 12 mins.

Since given that she runs for 3 mins and in the above choice the given date is she is running for 10 mins it is neither 3 nor multiple of 3.

Hence this is Choice is Incorrect.

B  Run for 15 minutes and lift weights for 25 mins.

Now Given in choice is that she runs for 15 minutes and in given data she runs for 3 minutes hence 15 is multiple of 3 and is multiplied by 5 also given lift weights for 25 mins and in given data she lift weights for 5 mins since 25 is multiple of 5 and is multiplied by 5.

Hence the above Choice is Correct.

C  Run for 20 mins and lift weights for 30 mins.

Since given that she runs for 3 mins and in the above choice the given date is she is running for 20 mins it is neither 3 nor multiple of 3.

Hence this is Choice is Incorrect.

D  Run for 24 mins and lift weights for 48 mins.

Now Given in choice is that she runs for 24 minutes and in given data she runs for 3 minutes hence 24 is multiple of 3 and is multiplied by 8 also given lift weights for 48 mins and in given data she lift weights for 5 mins and 48 is not the multiple of 5.

Hence this is Choice is Incorrect.

E  Run for 30 mins and lift weights for 50 mins.

Now Given in choice is that she runs for 30 minutes and in given data she runs for 3 minutes hence 30 is multiple of 3 and is multiplied by 10 also given lift weights for 50 mins and in given data she lift weights for 5 mins since 50 is multiple of 5 and is multiplied by 10.

Hence the above Choice is Correct.

Answer:

no

Step-by-step explanation:

there are two coordinates with the same x value

George shovels at a rate of 8.33 square yards per hour. In 5 1/2 hours, he will shovel approximately 45.815 square yards of his driveway.

The student asked about how many square yards of driveway George would shovel in 5 1/2 hours after shoveling 12 2/4 square yards in 1 1/2 hours. To find this, we first need to calculate the rate at which George is shoveling.

George shovels 12 2/4 square yards in 1 1/2 hours. Simplifying these fractions, we have 12.5 square yards in 1.5 hours. The rate is therefore 12.5 ÷ 1.5 yards per hour = 8.33 square yards per hour.

Next, we multiply this rate by the total time George will be shoveling to find how much he would shovel in 5 1/2 hours:

8.33 yards/hour × 5.5 hours = 45.815 square yards

So, George will shovel approximately 45.815 square yards of his driveway in 5 1/2 hours.

Final answer:

To find out how many square yards of driveway George would shovel in 5 1/2 hours, we can set up a ratio using the given information and multiply the rate by the time.

Explanation:

To find out how many square yards of driveway George would shovel in 5 1/2 hours, we can set up a ratio using the given information. In 1 1/2 hours, he shovels 12 2/4 square yards of snow. We can write this as a fraction: 12 2/4 / 1 1/2. To simplify this fraction, we can convert the mixed numbers to improper fractions: 50/4 / 3/2.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: (50/4) × (2/3). Multiplying the numerators and denominators, we get (50 × 2) / (4 × 3) = 100/12.

So, in 1 1/2 hours, George shovels 100/12 square yards of snow. To find out how many square yards he would shovel in 5 1/2 hours, we can multiply this rate by 5 1/2: (100/12) × (5 1/2). Multiplying the numerators and denominators, we get (100 × 11) / (12 × 2) = 1100/24. Simplifying this fraction, we get 275/6.

Therefore, George would shovel approximately 275/6 square yards of driveway in 5 1/2 hours.

It takes 10.155 years until you have $3,000 ⇒ 3rd

Step-by-step explanation:

The formula for compound interest, including principal sum is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex] , where

∵ You decide to put $2,000 in a savings account

∴ P = 2000

∵ You want to save for $3,000

∴ A = 3000

∵ The account has an interest rate of 4% per year and is

   compounded monthly

∴ r = 4% = 4 ÷ 100 = 0.04

∴ n = 12 ⇒ compounded monthly

- Substitute all of these values in the formula above to find t

∵ [tex]3000=2000(1+\frac{0.04}{12})^{12t}[/tex]

- Divide both sides by 2000

∴ [tex]1.5=(1+\frac{1}{300})^{12t}[/tex]

∴ [tex]1.5=(1\frac{1}{300})^{12t}[/tex]

- Change the mixed number to an improper fraction

∴ [tex](1.5)=(\frac{301}{300})^{12t}[/tex]

- Insert ㏒ for both sides

∴ [tex]log(1.5)=log(\frac{301}{300})^{12t}[/tex]

- Remember [tex]log(a)^{n}=nlog(a)[/tex]

∴ [tex]log(1.5)=(12t)log(\frac{301}{300})[/tex]

- Divide both sides by [tex]log(\frac{301}{300})[/tex]

∴ 121.84 = 12 t

- Divide both sides by 12

∴ 10.155 = t

It takes 10.155 years until you have $3,000

Answer:

The required equation models the total profit, y, based on the number of hot dogs sold, x  is   y = 3 x - 30.

Step-by-step explanation:

Let x = total number of hot dogs sold

y = total profit from total sales of hot dogs

The given situation can be written as: y = m x +  C  ......[A]

Now, Profit for 40 hot dogs = $90 profit

So, here this can be written as:

90 = 40 m + C ......[1]

Profit for 80 hot dogs = $210 profit

So, here this can be written as:

210 = 80 m + C ......[2]

Now, solving both the equations, we get:

Subtracting  [1] and [2], we get

210  - 90  = 80 m + C  - (40 m + C)

or, 120 = 40 m

or, m = 120/40 = 3

or, m = 3

Solving for the value of C , we get: C = - 30

Putting the value of m back in the equation : y   = m x + C

y = 3 x -30

Hence, the required equation models the total profit, y, based on the number of hot dogs sold, x  is   y = 3 x - 30.

Answer:

The area at time t is given  by [tex]A(t) =\pi (4t^2+2t+0.25).[/tex]

Step-by-step explanation:

We know the radius [tex]r(t)[/tex] of the oil spill as a function of time, and we know the area [tex]A(r)[/tex] as a function of radius, and we want the area at time t. In other words we are looking for area as a function of time [tex]A(t)[/tex]

We find [tex]A(t)[/tex] by putting [tex]r(t)[/tex]  into [tex]A(r)[/tex] as a substitute to r:

[tex]A(t) = A(r(t))= \pi r(t)^2 =\pi (0.5 + 2t)^2={\pi (4t^2+2t+0.25).}[/tex]

[tex]\boxed{A(t) =\pi (4t^2+2t+0.25).}[/tex]

Which is our answer.

To find the composite function for the area of the oil spill over time, replace 'r' in A(r) = πr2 with the function r(t). The function becomes A(t) = π(0.5 + 2t)2.

In order to find the function that represents the area of the oil spill over time, we need to write a composite function. This means we plug the function r(t) into A(r). Since r(t) = 0.5 + 2t, you can replace every instance of 'r' in A(r) = πr2 with (0.5 + 2t) to get the area as a function of time 't'. So, the composite function becomes A(t) = π(0.5 + 2t)2. Now we have a composite function that represents the area of the oil spill, denoted by A(t), as a function of time. The function is: A(t) = π(0.5 + 2t)2.

The average annual income, I, in dollars, of a lawyer with an age of x years is modeled with with the following function:

I = - 425x² + 45500x - 650000 .......... (1)

If the average annual income of the lawyer at the age of x years is $250000, then from the equation (1) we can write

- 425x² + 45500x - 650000 = 250000
