Answer:

[tex]2\pi \approx 6.28\ meters[/tex]

Step-by-step explanation:

Mei's horse is 3 meters from the center of the carousel. After one rotation, Mei travelled

[tex]l_M=2\pi r=2\pi \cdot 3=6\pi\ meters[/tex]

Anju's horse is 2 meters from the center. After one rotation, Mei travelled

[tex]l_A=2\pi r=2\pi \cdot 2=4\pi\ meters[/tex]

The difference in their travelled distances is

[tex]l_M-l_A=6\pi -4\pi =2\pi \approx 6.28\ meters[/tex]

Mei travels 6.28 meters more than Anju in one rotation.

In one rotation, Mei's horse travels a distance of

2 * 3.14 * 3 = 18.84 meters.

In one rotation,

Anju's horse travels a distance of 2 * 3.14 * 2 = 12.56 meters.

Therefore, Mei travels 18.84 - 12.56 = 6.28 meters more than Anju in one rotation.

The solutions to the quadratic equation 3x^2 - 7x - 1 = 0, using the quadratic formula, are x = [7 + sqrt(61)]/6 and x = [7 - sqrt(61)]/6.

This question pertains to the solving of a quadratic equation using the quadratic formula. The quadratic formula is given by x = [-b ± sqrt(b^2 - 4ac)]/2a. In equation 3x^2 - 7x - 1 = 0, comparing it with the standard form of quadratic equation ax^2 + bx + c = 0, we can assign: a = 3, b = -7, and c = -1. Substituting these values into the formula, we get: x = [7 ± sqrt((-7)^2 - 4*3*(-1))]/2*3 = [7 ± sqrt(49 + 12)]/6 = [7 ± sqrt(61)]/6. So, the solutions to the equation are x = [7 + sqrt(61)]/6 and x = [7 - sqrt(61)]/6.

Answer:

Step-by-step explanation: 282 divided by 94 = 3

4x3=12

Answer:

12 defective widgets

Step-by-step explanation:

Here we calculate the "experimental probability:" 4 defective widgets out of 94 widgets comes out to a probability of being defective of 4/94, which of course could be reduced.

But we can go ahead and calculate the expected number of defective widgets by mult. that 282 widgets by the probability 4/94:

282        4

------- * ------- = 12

   1         94

In this sample of 282 widgets, we could expect that 12 will be defective.

Answer:

x = 13.

So the 3 angles are a =  44, b = 47 and c = 89 degrees.

Step-by-step explanation:

If these are the angles  are the 3 angles of a triangle they sum to 180 degrees, so:

3x + 5 + 5x - 18 + 7x - 2 = 180

15x - 15 = 180

15x = 195

x = 195/15

x = 13.

To find the values of angles a, b, and c given by the expressions 3x + 5, 5x - 18, and 7x - 2, we set up and solve equations involving these expressions. Once we find the value of x, we substitute it back into the expressions to find the angles.

The question asks about angles given by the expressions a= 3x + 5, b= 5x - 18, and c= 7x - 2. In order to find the values of x and the corresponding values of angles a, b, and c, we need to set up and solve equations involving these expressions.

We can equate these expressions to given angles or to each other, and solve for x. Once we find the value of x, we can substitute it back into the expressions to find the angles.

For example, to find angle a, we substitute the value of x into the expression 3x + 5. Similarly, we substitute the value of x into the expressions 5x - 18 and 7x - 2 to find angles b and c, respectively.

Answer: l = 7.2

Step-by-step explanation:

90/12.5 = 7.2

7.2 * 12.5 = 90

Answer:

length of the rectangle is 7.2 centimeters.

Step-by-step explanation:

Area of the rectangle has been given as 90 square centimeters.

Height of the rectangle = 12.5 centimeters

Now we have to calculate the length of the rectangle.

Since, Area of the rectangle = Length × height

90 = 12.5 × length

Length = [tex]\frac{90}{12.5}[/tex]

           = 7.2 centimeters

Therefore, length of the rectangle is 7.2 centimeters.

Answer:

x = - 2, x = 4

Step-by-step explanation:

Given

f(x) = (x - 4)(x + 2)

To find the x- intercepts let f(x) = 0, that is

(x - 4)(x + 2) = 0 ← in standard form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4 → (4, 0 )

x + 2 = 0 ⇒ x = - 2 → (- 2, 0 )

Answer:

Step-by-step explanation:

40%=0.4

0.4*25=10

To calculate 40 percent of 25, you use the equation 0.40 x 25. This equation multiplies the decimal form of 40 percent by the total, which in this case is 25, resulting in the value of the part that represents 40 percent.

To find 40 percent of 25, you can use the equation that incorporates the base value (25) and the percentage you want to find (40%). In this case, the equation you're looking for is 0.40 x 25, which will give you the answer for what is 40 percent of 25.

Percentages can be calculated by using the formula: 'part over total, times one hundred, equals percent'. For example, if you have 25 students and want to find out what 40% of that number is, you would calculate 40/100, which is 0.40, and multiply by 25. The equation 0.40 x 25 is thus used to solve for the desired percentage.

Givens

So, [tex]x[/tex] represents the number of sandwiches and [tex]y[/tex] represents the number of wraps, so the profit on each food is

[tex]2x[/tex] and [tex]3y[/tex], so the sum of them must be equal to $1470, as follows

[tex]2x+3y=1470[/tex]

Which is a linear equation, that means if we graph, it would be a line.

To graph this, we just need to find two points.

Step-by-step explanation:

The offered overtime hourly rate is 1.5 times the given hourly rate.

The amount Colin Katz earns per hour = $10.75

The number of additional hours Colin Katz is asked to work = 2 hours

Rate at which the additional hours will be paid = Hourly rate and half = 1.5 hourly rate

The amount he will earn for the additional hours.

The hourly rate for the additional hours = 1.5 × $10.75 = $16.125

Amount Colin Katz earns working 2 additional hours = 2 × $16.125 = $32.25

Answer:

3√5 or ≈6.7082

Step-by-step explanation:

1) √45

2) Factor out the perfect square: √3²×5

3) The root of a product is equal to the product of the roots of each factor: √3²√5

4) Reduce the index of the radical and exponent with 2: 3√5

5) Solution: 3√5 or ≈ 6.7082

after removing the perfect square factor from inside the square root of 45, we are left with 3√5.

To remove all perfect squares from inside the square root of √45, we need to factorize 45 and separate the perfect square factors.

The prime factorization of 45 is 3 × 3 × 5. Since 3 is repeated twice, it represents a perfect square factor.

We can rewrite the square root of 45 as the square root of (3 × 3 × 5). Using the property of square roots (√ab = √a × √b), we can simplify it as √(3 × 3) × √5.

The square root of 3 × 3 equals 3, so the expression simplifies to 3√5.

Therefore, after removing the perfect square factor from inside the square root of 45, we are left with 3√5.

Step-by-step explanation:

Because they just added the same equality. And when you move the -7 over the equal sign it makes it positive so it would be p^2 + 5 + 7 = 8p and that makes it p^2 + 12 = 8p

The property used by the kate to write the function p^2 + 5 = 8p - 7 as p^2 + 12 = 8p is the addition property of equality.

Given to us

When solving p^2 + 5 = 8p - 7.

Kate wrote p^2 + 12 = 8p.

As we can see Kate has simply added the number one, therefore, she had used the addition property of equality.

[tex]p^2 + 5 = 8p - 7\\\\p^2+5+7=8p\\\\p^2 + 12=8p[/tex]
