Tom has a total of $220 and he spent $35 on a baseball ticket. What percent of his money did he have left

The least number of seats she is setting up 40 seats are needed.

The least number is zero (0). Zero (0) is the smallest natural number and is the additive identity of the set of whole numbers. It is the only number that is neither positive nor negative and is, therefore, regarded as neither odd nor even. Zero (0) is essential in mathematics and is used to represent the absence of a quantity. It is also used to represent the additive identity of real numbers and complex numbers.

Given: Mandy can place 8 seats at each table or 10 seats at each table with no left over.

We have to find the least number of seats needed.

Find the prime factors of 8:

⇒ 8 = 2 x 2 x 2 = 8 = 2³

Find the prime factors of 10:

⇒ 10 = 2 x 5

Find the LCM of 8 and 10:

⇒ 8 = 2³

10 = 2 x 5

LCM = 2³ x 5

LCM = 40

Hence, a minimum of 40 seats are needed.

Answer:

Step-by-step explanation:

You want the complete solution (side lengths and angles) for a right triangle with leg lengths a=13 ft and b=16 ft.

Since the two leg lengths are given, it is convenient to use the inverse tangent relation to find one of the acute angles.

  Tan = Opposite/Adjacent

  tan(A) = a/b

  A = arctan(13/16) ≈ 39°

  B = 90° -A = 51°

The hypotenuse can be found using the Pythagorean theorem, or it can be found using trigonometry. We have just computed angle A, so we can use that value to find the hypotenuse of the triangle.

  Cos = Adjacent/Hypotenuse

  Hypotenuse = Adjacent/Cos

  c = b/cos(A) = 16/cos(39.093859°) ≈ 21 . . . . feet

Then the solution is ...

Additional comment

Note the calculator is set to DEG mode so the angles are reported in degrees.

The hypotenuse is found using the original full-precision value of the angle, not the rounded value required to answer the problem statement.

Answer: A. To find the probability that a randomly selected male passenger can fit through the doorway without bending, we need to find the probability that his height is less than or equal to 72 inches. Since the heights of men are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches, we can use the standard normal distribution to find this probability.

The standard normal distribution has a mean of 0 and a standard deviation of 1. We can convert the height of a male passenger from the given distribution to the standard normal distribution by using the formula:

$z = \frac{x - \mu}{\sigma}$

where $x$ is the height of the male passenger, $\mu$ is the mean height of 69 inches, and $\sigma$ is the standard deviation of 2.8 inches. Substituting these values into the formula gives us:

$z = \frac{72 - 69}{2.8} = \frac{3}{2.8} = 1.0714$

Since the standard normal distribution is symmetric, the probability that a male passenger's height is less than or equal to 72 inches is the same as the probability that his height is greater than or equal to 72 inches. We can find this probability by looking up the value of $z = 1.0714$ in a standard normal table, which gives us a probability of 0.8413. Therefore, the probability that a male passenger can fit through the doorway without bending is 0.8413.

B. To find the probability that the mean height of the 175 men is less than 72 inches, we need to find the probability that the sample mean is less than 72 inches. Since the heights of men are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches, the sample mean will also be normally distributed with a mean of 69 inches and a standard deviation of $\frac{2.8}{\sqrt{175}} = 0.32$. We can use the standard normal distribution to find the probability that the sample mean is less than 72 inches.

The standard normal distribution has a mean of 0 and a standard deviation of 1. We can convert the sample mean from the given distribution to the standard normal distribution by using the formula:

$z = \frac{x - \mu}{\sigma}$

where $x$ is the sample mean, $\mu$ is the mean of 69 inches, and $\sigma$ is the standard deviation of 0.32. Substituting these values into the formula gives us:

$z = \frac{72 - 69}{0.32} = \frac{3}{0.32} = 9.375$

Since the standard normal distribution is symmetric, the probability that the sample mean is less than 72 inches is the same as the probability that the sample mean is greater than 72 inches. We can find this probability by looking up the value of $z = 9.375$ in a standard normal table, which gives us a probability of 0.0000. Therefore, the probability that the mean height of the 175 men is less than 72 inches is 0.0000.

C. When considering the comfort and safety of passengers, the result from part (a) is more relevant than the result from part (b). This is because part (a) tells us the probability that a randomly selected male passenger can fit through the doorway without bending, which is directly relevant to the comfort and safety of the passengers. In contrast, part (b) tells us the probability that the mean height of the 175 men is less than 72 inches, which is not directly relevant to the comfort

D. Women are ignored in this case because the problem only asks about the heights of men. The problem states that the heights of men are normally distributed with a mean of 69 inches and a standard deviation of 2.8 inches, and does not provide any information about the heights of women. Therefore, we cannot use the given information to find the probability that a female passenger can fit through the doorway without bending.

Amy buys 12 envelopes for 26p each, so the total cost is 12 x 26 = 312p. She pays with a £5 note, which is equal to 5 x 100 = 500p. Therefore, she gets 500 - 312 = 188p in change. This is equal to £1.88.

Mathematics deals with the relationship between two numbers or quantities using the notions of ratio and proportion. Two numbers are compared in a ratio, which is often represented as a fraction. For example, the ratio of pounds to oranges in a basket could be 3:2, implying that there are three apples for every two oranges. Contrarily, proportion is the connection between two ratios. It is an equation, in other words, when two ratios are equal. The ratio of apples to oranges in a basket may be 3:2, whereas the ratio of apples to all the other fruits in the basket might be 9:11. In this case, the two ratios are proportionate since 3/2 = 9/11.

19.89% is the percentage decrease of the depth of the lake from January to August.

A quantity or ratio can be expressed as a percentage of 100 by using the word "percentage." Comparing two or more numbers and illustrating how significantly one number differs from the other in proportion to the whole is a popular usage for this technique. If a baseball originally costs $12 and is discounted by 20%, for instance, its new price would be $12 x 20/100 = $2.40 less than the original price. In other words, after the reduction, the ball will cost $12 - $2.40 = $9.60. A percentage may often be determined by dividing a quantity by its entirety and multiplying the result by 100. For instance, if a baseball bat costs $100 and is reduced by 30%, its new cost would be $100 x 30/100, which equates to $30 less.

How to solve?

The depth of the lake decreased by 943 - 754.4 = 188.6 feet from January to August.

The percentage decrease is (188.6 / 943) x 100 = 19.89%

The exponential function best represents the growth of the investment.

What is exponential function?

An exponential function can be used to depict the investment's growth. The formula for an exponential function is y = a * b^x, where an is the starting point (in this case, 45,000), b is the growth factor (in this case,

1 + 0.018 = 1.018), and x is the number of time periods (in this case, the number of months).

For example, if we let x represent the number of months, the function would be:

y = 45,000 * 1.018^x

This function represents the growth of the investment as a function of the number of months. As the number of months increases, the value of the investment will grow exponentially according to the formula.

Hence, the exponential function best represents the growth of the investment.

Answer: I think its 3.5

Step-by-step explanation:

The equation of the tangent line to the curve when y = -1 is y = -4x - 1.

To find the equations of all tangent lines to the curve when y = -1, we can use the definition of a tangent line, which is a line that touches a curve at a single point and has the same slope as the curve at that point.

To find the slope of the curve at a given point, we can use the slope formula:

slope = (y₂ - y₁) / (x₂ - x₁)

In this case, we can set y₁ = -1 and y₂ = -1 + h, where h is a small positive number, and find the corresponding value of x₂ by substituting these values into the equation x - x²y - 2y² = 0. This will give us the slope of the curve at the point (x, -1).

Substituting these values into the equation, we get:

x - x²(-1) - 2(-1 + h)² = 0

Expanding the second term and rearranging, we get:

x - x² + 2(1 - 2h + h²) = 0

This simplifies to:

x - x² + 2 - 4h + 2h² = 0

This can be rewritten as:

x - x² + 2h² - 4h + 2 = 0

To find the slope of the curve at the point (x, -1), we can take the derivative of this equation with respect to x and evaluate it at x = x and h = 0:

slope = (2h² - 4h)'|h=0

= 0 - 4

= -4

Now that we have the slope of the curve at the point (x, -1), we can use the point-slope form of a linear equation to find the equation of the tangent line:

y - (-1) = -4(x - x)

y + 1 = -4x

y = -4x - 1

Therefore, when y = -1, the equation of the tangent line to the curve is y = -4x - 1.
