Answer: 261

Step-by-step explanation:

You use PEMDAS to solve this problem

you first do the Parenthesis (p)

33+6(2+36)

33+6 (38)

We then multiply first (M)

33 + 6(38) - we know that 8 times 6 is 48 ; 6 times 3 is 18 +4 because we brought down the 4 from 48 to 3. which will be equal to 228

33 + 228

Answer:

The dimensions of the sports field are 80 yards and 3 - 5x yards

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Width of the sports field = At least 60 yards

Area of the sports field = 240 - 400x square yards

We can conclude the shape of the sports field is rectangular.

2. Find the dimensions of the sports field.

A. We need to find the Greatest Common factor between 240 and 400, this way:

The factors of 240 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 .

The factors of 400 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 .

Then the greatest common factor is 80.

This GCF is also higher than 60, therefore it's one of the dimensions of the sports field.

Now, we calculate the other side of the sports, this way:

Second dimension of the sports field = (240 - 400x)/80

Second dimension of the sports field = 3 -5x

The dimensions of the sports field are 80 yards and 3 - 5x yards

Answer:

80(3-5x)

Step-by-step explanation:

240-400x

GCF: 80

Factored expression: 80(3-5x)

Answer: An equilateral triangle can NOT be a right triangle.

Answer:

46 housewives read all three magazines.

Step-by-step explanation:

Given:

        n(A) = 150

        n(B) = 200

        n(C) = 156

        n(A∩B) = 48

        n(B∩C) = 60

        n(A∩C) = 52

         n(A∪B∪C) = 300

so we know the relation as:

  n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)

∴ n(A∩B∩C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C)  - n(A∪B∪C)

                    = 150 + 200+ 156 - 48 - 60 - 52 - 300

                   = 46

Hence the number of housewives that had read all three magazine is 46.

Answer:

46 housewives read all three magazines.

The number of full time employees is 17 and the number of part time employee is 9

Step-by-step explanation:

Step 1 :

Let f represent the number of full time employee and p represent the number of part time employee

Total number of employees = 26

Hence we have f + p = 26

Step 2 :

Wages of full time employee  = $275

Wages of part time employee = $140

Total wages paid by Jeds = $ 5935

Hence we have 275 f + 140 p = 5935

Step 3:

Solving the equations obtained in step 1 and step 2 we have

f + p = 26, Multiplying by 275 = > 275 f + 275 p = 7150

275 f + 140 p = 5935

Subtracting equation 2 from 1 we have

135 p = 1215 => p = 9

Substituting this in f + p = 26 gives, f + 9 = 26

So f = 17

Step 4 :

Answer :

The number of full time employees is 17 and the number of part time employee is 9

Answer:

B.  No

Step-by-step explanation:

We can test this theory using Pythagorean's theorem:

a² + b² = c²

12² + 20² = 24²

144 + 400 = 576

544 ≠ 576

So you can conclude that this is not a right triangle.

Answer:

202.8

Step-by-step explanation:

The geometric mean of 2 numbers a and b is

[tex]\sqrt{ab}[/tex]

Here a = 30 and mean = 78, thus

[tex]\sqrt{30b}[/tex] = 78

To clear the radical square both sides

([tex]\sqrt{30b}[/tex] )² = 78², that is

30b = 6084 ( divide both sides by 30 )

b = [tex]\frac{6084}{30}[/tex] = 202.8

Solution:

Given that,

The costs for going to a dog beach are $7 for 1 dog, and $2 for each  additional dog

Let "x" be the number of dogs

where x is greater  than or equal 1

Cost y is $7 for the first dog and $2 for each of the other dogs

Therefore,

y = 7 + 2(x - 1)

x - 1 means the additional dogs

Therefore,

y = 7 + 2x - 2

y = 2x + 5

Thus the equation is found

Using distance formula we find that length is 13.

Answer:

around $6000 the real answer is $5253.5

Step-by-step explanation:

Answer:

y= 2/3x + 28/3

Step-by-step explanation:

First, write your equation as y=2/3x+b. Plug in your coordinate into the equation, it should look like this: 6=2/3(-5)+b. Multiply 2/3 by -5 to get -10/3. It should look like this: 6= -10/3+b. Add 10/3 to both sides to get your y-intercept of 28/3. Go back to your original equation and plug 28/3 into b. This is your final equation: y= 2/3x + 28/3. Hope this helped!

Answer:

330 degrees

Step-by-step explanation:

a full rotation is 360 degrees and if you subtract 30 from 360 its 330

Final answer:

To complete a full rotation, Greg's ceiling fan, which has already rotated 30 degrees, needs to rotate one more time, as there are 330 degrees left to reach 360 degrees, which is a full rotation.

Explanation:

Greg's ceiling fan rotates 30 degrees and stops. To determine how many more times the fan needs to rotate to complete a full rotation, first, we need to know that one full rotation is equal to 360 degrees. As the fan has already rotated 30 degrees, we subtract this from 360 degrees:

360 degrees - 30 degrees = 330 degrees.

Now, because one full rotation is 360 degrees, we divide the remaining degrees by 360 to find the number of additional rotations needed:

330 degrees / 360 degrees per rotation = 0.9167 rotations.

Since a fan cannot complete a fraction of a rotation in terms of action, Greg's ceiling fan would need to rotate one more time to make it a complete rotation.

To calculate the original price of a wagon on sale at 20% off, divide the sale price of $114 by 0.80, resulting in the original price of $142.50.

To find the original price of the wagon before the 20% sale, we have to determine what $114 represents after the discount has been applied. If $114 is 80% of the original price (100% - 20% = 80%), we need to find 100% by dividing $114 by 0.80:

Original Price = Sale Price / (1 - Discount Percentage)

Original Price = $114 / 0.80

Original Price = $142.50

So, the original price of the wagon before the sale was $142.50.

Differential equation is a way to represents the relation between the functions and their variables. The solution to the differential equation given in the question is,

[tex]y=\dfrac{3}{15x-1}[/tex]

Given-

The equation in the question is,

[tex]{dy\times {dx}=5y^2[/tex]

Differential equation is a way to represents the relation between the functions and their variables.

Rewrite the equation,

[tex]\dfrac{dy}{5y^2} =dx[/tex]

Integration both sides,

[tex]-\dfrac{1}{5y} =x+c[/tex]

Here, c is the integrating constant.

Now the given initial condition is,

[tex]y(0)=3[/tex]

Use this for the integrated function to find the value of the constant,

[tex]-\dfrac{1}{5\times 3} =c[/tex]

[tex]c=-\dfrac{1}{15}[/tex]

Put this value in equation we get,

[tex]-\dfrac{1}{5y} =x-\dfrac{1}{15}[/tex]

[tex]y=\dfrac{3}{15x-1}[/tex]

Hence the solution to the differential equation given in the question is,[tex]y=\dfrac{3}{15x-1}[/tex]

To solve the differential equation dy/dx = 5y^2 with the initial condition y(0) = 3, use separation of variables and integration. Substitute the initial condition to find the specific solution.

To solve the differential equation dy/dx = 5y^2 with the initial condition y(0) = 3, we can use separation of variables.

First, rewrite the equation as dy/y^2 = 5dx. Integrate both sides: ∫1/y^2 dy = ∫5 dx. This simplifies to -1/y = 5x + C.

Next, apply the initial condition y(0) = 3: -1/3 = 0 + C. Therefore, C = -1/3.

Substitute C back into the equation: -1/y = 5x -1/3. Solve for y: y = -1/(5x -1/3).
