Which fractions are equivalent to 40%?

Answer:

w=9 feet

l=11 feet

Step-by-step explanation:

Let the length of the rectangle be l and width be w

Condition 1:

l=2+w --------(I)

Condition 2:

2l+2w=40--------(2)

Putting eq (1) in (2)

2(2+w)+2w=40

4+2w+2w=40

4+4w=40

4w=40-4

4w=36

Dividing both sides by 4

w=9

Now

Putting w=9 in eq (1)

l=2+9

l=11

Answer:

95%

Step-by-step explanation:

We have that:

The number of potato chips in a bad is normally distributed with a mean of 75 and a standard deviation of 5.

We want to use the empirical rule to solve this:

We know that:

65=75-2(5)

That means

[tex]65 = 75 - 2 \sigma[/tex]

Also, 85=75+2(5)

[tex]85 = 75 + 2 \sigma[/tex]

According to the the empirical rule approximately 95% of the distribution is within 2 standard deviation of the mean

Answer:

1/10

Step-by-step explanation:

1/6 / 1 2/3

Convert 1 2/3 to 5/3.

1/6 / 5/3

1/6 x 3/5

3/30 or 1/10

The result of the division of 1/6 by 1 2/3 can be found by first converting 1 2/3 to an improper fraction, then taking the reciprocal of this fraction and multiplying it by 1/6. This gives the result as 1/10.

To solve this fraction division problem, we first need to convert the mixed number 1 2/3 to an improper fraction. A mixed number like 1 2/3 means one plus 2/3, and it can be converted to an improper fraction by multiplying the whole number by the denominator and adding the numerator. For 1 2/3, this means: (1*3 + 2)/3 = 5/3.

Now, we have the problem 1/6 / 5/3. In fraction division, we can replace the division with multiplication by the reciprocal of the second fraction. The reciprocal of a fraction is created by switching the numerator and the denominator. So, the reciprocal of 5/3 is 3/5.

Our equation 1/6 / 5/3 then becomes 1/6 * 3/5 = 3/30 = 1/10 when simplified. Hence, the result of 1/6 divided by 1 2/3 in its simplest form is 1/10.

No. In fact, you divide it into two.

So let's say the diameter is 10 cm.

To get the radius, you halve it or divide by two.

10 ÷ 2 = 5 cm

The radius of a circle with a 10 cm diameter is 5 cm.

Answer: No

Step-by-step explanation: You have to divide it by two to to have the radius.

1. A line joining the two sides of a circle is called diameter.

2. This line actually divide the circle into halves.

3. The radius of a circle is the length of the circle from the centre position.

5. The radius is half the dimension of diameter.

6. Now we can prove that radius(r) is equal to diameter/2

r=d/2.

Simplified expression is 6y² - 24y - 51. Value for y=-2 is 21 and value for y=3 is  -69.

Step-by-step explanation:

⇒ 6y² - 21y - 3y + 12 - 63

⇒ 6y² - 24y - 51

⇒ 6y² - 24y - 51 = 6(-2)² - 24(-2) - 51 = 24 + 48 - 51 = 21

⇒ ⇒ 6y² - 24y - 51 = 6(3)² - 24(3) - 51 = 54 - 72 - 51 = -69

Answer:

b= -8

Step-by-step explanation:

we have: 3y +12 = 6x <=> y + 4 = 2x <=> y= 2x - 4

=> 2y=4x + b

<=> 4x - 8= 4x +b

<=> b = -8

The vertical axis of the given ellipse x^2/4 + y^2/16 = 1 is 8 units long, and each semimajor axis for an ellipse with a major axis of 16 cm would be 8 cm. An ellipse with an eccentricity of 0.8 would be considered elongated.

The ellipse given by the equation x^2/4 + y^2/16 = 1 has a vertical major axis. This can be deduced because the larger denominator is under the y^2 term, meaning the ellipse stretches further in the y-direction. In this case, the length of the major axis is 2 times the square root of 16, which is 2 times 4, equaling 8. Therefore, the major axis is 8 units long, and since each semimajor axis is half of the major axis, the semimajor axis would be 4 units long. Consequently, for the given options, the vertical axis of the ellipse is 8.

Considering a different ellipse with a major axis of 16 cm, the semimajor axis would be half of this length, resulting in 8 cm. If such an ellipse has an eccentricity of 0.8, it is more elongated than circular. Typically, ellipses with lower eccentricities (closer to 0) appear more circular, while those with higher eccentricities (closer to 1) appear more elongated.

To determine the house's value over time, a function can be created using the initial value and an annual growth rate. Specific details about the growth rate are needed for an accurate function, but a generic formula with a constant rate can still be provided.

Creating a Function for House Value Over Time

To write a function that determines the value of a house in thousands of dollars based on the number of years since purchase, we would need additional information about how the house's value appreciates or depreciates over time. This could involve a fixed annual appreciation rate, market trends, renovations, or depreciation.

Without specific data, a generic function can still be proposed, assuming a constant annual percentage increase. Let's call the annual growth rate 'r' (in decimal form) and the original value of the house 'V'. The function would then be:

f(t) = V × (1 + r)^t

For example, if Kyle bought the house at a value of $100,000 (or 100 in thousands of dollars) and the annual growth rate is 3% (or 0.03), the function defining the future value of the house would be:

f(t) = 100 × (1 + 0.03)^t

Using this formula, we can calculate the future value of Kyle's house after any number of years 't'.

B: The domain represents a 11-month period of flower production.

Step-by-step explanation:

The domain of a Function

It's the set of all the values a function can take in its independent variable. The independent variable (usually x) is represented as the horizontal axis of a graph, where we can know the interval of values considered for values of the function.

In the provided graph, we can see the horizontal axis is labeled 'Months' and its values range from 1 to 11. The vertical axis is labeled "Number of flowers produced" which will be the Range of the function.

From the options presented, we can discard the C and D because they are related to the number of flowers produced, which is not the domain of the function. The option A talks about the months of production but the months range up to 180. Option B is the correct choice.

B: The domain represents a 11-month period of flower production.

Step-by-step explanation:

Equation of the given line is :

[tex] 2x +12y= - 1\\

\therefore 12y = - 2x - 1\\

\therefore y = \frac {- 2}{12}x - \frac {1}{12}\\

\therefore y = - \frac {1}{6}x - \frac {1}{12}\\[/tex]

Equating above equation with [tex] y= m_1x + c

Final answer:

To solve the equation -2/9m + 12 = -8 for m, subtract 12 from both sides, then multiply by -9/2. The solution is m = 90.

Explanation:

To solve the equation -2/9m + 12 = -8 for m, start by isolating the term involving m. Subtract 12 from both sides of the equation to get:

-2/9m = -8 - 12

-2/9m = -20

Next, multiply both sides by -9/2 to solve for m:

m = (-20) * (-9/2)

m = 180/2

m = 90

Therefore, the solution to the equation is m = 90.

The distance along the path of the ship be within the range of the torpedoes is 4 kilometers.

Explanation:

The submarine lies 3 km from the target ship.

Let B denotes the target ship and C denotes the submarine.

Let AC denotes the the target ship would be within the range of the torpedoes.

The image attached below illustrates that the distance between submarine and the target ship and the range of the torpedoes.

Let BC denotes the distance between the target ship and the submarine. Let AC denotes the range of the torpedoes.

To determine the length of AB, let us use Pythagorean theorem,

[tex]AC^{2} =AB^{2} +BC^{2}[/tex]

Substituting the values of BC = 3 and AC = 5, we have,

[tex]5^{2} =AB^{2} +3^{2}[/tex]

Squaring the terms, we get,

[tex]25 =AB^{2} +9[/tex]

Subtracting both sides by 9, we have,

[tex]16 =AB^{2}[/tex]

Taking square root on both sides,

[tex]AB = 4[/tex]

Thus, the distance along the path of the ship be within the range of the torpedoes is 4 kilometers.

Using zero as a counterexample, it disproves the conjecture '-x is negative', because when x=0, -x (which becomes -0) equals 0, not negative.

A counterexample is an example that disproves a statement or proposition. In this case, we are given the conjecture '-x is negative'. If x is an integer, it can be positive, negative, or zero. To counter this statement, we can use zero as a counterexample. When x=0, -x (which becomes -0) is not negative but equals to 0. This proves that the original conjecture is not always correct, as it can have exceptions.
