To see your eyes reflected in the mirror, the mirror needs to be tilted at an angle of 33.02°.

Given,

You look down at a little vertical mirror hanging on the wall as you are standing 1.55 meters in front of it. You may see your shoes reflected in this mirror. How far should the mirror be slanted for you to see your eyes mirrored if your eyes are 1.95 meters above your feet? (The mirror is still in the same place, but its angle to the vertical has changed.)

Now, by assuming we have,

The height at which the eyes are above the feet y = 1.95

The distance between the person and wall x = 1.55

From a triangle,

tan∅ = (y/2) / x

tan∅ = (1.95/2) / 1.55

∅ = 33.02°

Hence, the mirror should be tilted for you to see your eyes reflected in the mirror by an angle of 33.02°.

The density of golf ball is 0.000113 gm/mm³

What is volume ?

Volume is a three dimensional space occupy by the body of particular shape such as here :

volume (V) of sphere with radius r : 4πr³/3

it is given that :

golf ball has a diameter d of = 42.67 millimeters

r = d/2 = 21.33 mm

golf ball has a mass m of = 45.93 grams

First, let us find the volume of the golf ball can be determined using the formula:

V = 4πr³/3

Substituting r = 21.33mm, we get;

V = 4π(21.33)³/3

V = 40650 mm³

Now, to find the number of grams per cubic millimeter of the material used to make the golf ball we find the density of golf ball :

ρ = m/V

ρ = 45.93/40650

ρ = 0.000113 gm/mm³

Therefore, the density of golf ball is 0.000113 gm/mm³

3 tickets to attend an Off-Broadway show cost $81,

4 tickets cost $108; and

5 tickets cost $135.

Let the price of a ticket=k

Therefore:

Solving any of the equation above gives: x=27

We therefore have:

\(\left|\begin{array}{c|c|c|c|c|c}$Tickets&1&2&3&4&5\\$Total Cost(\$)&27&54&81&108&135\end{array}\right|\)

Let y be the total cost of x tickets

An equation for the relationship is therefore:

y=27x (where x is the number of tickets and y is the total costs (in $)).

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:

5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8

Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

answer: 16 plates

I apologize if this is an incorrect answer,however, I believe that the fraction was added to throw you off. so if you divide the number of bowls you get 2 and then you multiply 8 by 2

If you spend all your money just on plates. Then the number of plates that you can buy will be 20.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Wendy spends 3/5 of her money on 3 bowls and 8 plates. With the rest of your money, you can buy another 6 bowls.

Let 'x' be the cost of each bowl, 'y' be the cost of each plate, and 'T' be the total amount of money. Then the equations are given as,

3x + 8y = (3/5) T          ...1

6x = (2/5) T

x = (1/15) T                 ...2

From equations 1 and 2, then the cost of each plate is calculated as,

3(1/15)T + 8y = (3/5)T

8y = 2/5

y = (1/20)T

If you spend all your money just on plates. Then the number of plates that you can buy will be given as,

Probability is a branch of mathematics that deals with the study of random events or phenomena. It is used to measure the likelihood or chance of an event occurring. Probability is represented as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, if a fair coin is flipped, the probability of getting heads is 1/2, since there is one favorable outcome (heads) out of two possible outcomes (heads or tails).

There are two main types of probability: theoretical probability and empirical probability.

Theoretical probability is based on mathematical calculations and assumes that all outcomes are equally likely. For example, the theoretical probability of rolling a six on a fair die is 1/6, since there is one favorable outcome out of six possible outcomes.

Empirical probability is based on observations and experiments and reflects the actual frequency of an event occurring. For example, the empirical probability of rolling a six on a particular die after many rolls may be different from the theoretical probability due to factors such as bias or chance.

Probability is used in many real-life situations, such as in games of chance, insurance, stock market analysis, and weather forecasting. It is also used in various fields of science, such as physics, biology, and chemistry, to model and analyze the behavior of complex systems.

Let's start by using algebra to represent the information given in the problem.

Let G be the number of green pins in the bag, and Y be the number of yellow pins in the bag. We know that:

G + Y is the total number of pins in the bag.

G/(G + Y) = 3/7, since 3/7 of the pins are green.

(G - 1)/[(G - 1) + Y] = 2/5, since after Yaqub gives a green pin to his sister, there are (G - 1) green pins remaining out of (G - 1 + Y) total remaining pins.

To solve for G and Y, we can use algebra to manipulate the equations:

G/(G + Y) = 3/7 can be simplified to 7G = 3(G + Y), which gives us 4G = 3Y.

(G - 1)/[(G - 1) + Y] = 2/5 can be simplified to 5(G - 1) = 2(G - 1 + Y), which gives us 3G - 2Y = 3.

We now have two equations with two variables, so we can solve for G and Y using substitution or elimination. For simplicity, we will use substitution.

From 4G = 3Y, we can solve for Y in terms of G:

Y = (4/3)G

Substituting this into 3G - 2Y = 3, we get:

3G - 2(4/3)G = 3

Simplifying, we get:

G = 9

Therefore, there are 9 green pins in the bag. Using the equation Y = (4/3)G, we get:

Y = (4/3)(9) = 12

So there are 12 yellow pins in the bag. After giving one green pin to his sister, Yaqub has 8 green pins and 12 yellow pins remaining in his bag. To check that 2/5 of the remaining pins are green, we can calculate:

8/(8+12) = 4/10 = 2/5

Therefore, the answer is that there are 8 green pins and 12 yellow pins remaining in the bag after Yaqub gives a green pin to his sister.

According to the EPA Clean Water Act regulations, all of the water that day is safe to drink.

To safeguard the standard of drinking water in the United States, the Safe Drinking Water Act (SDWA) was created. This legislation applies to all waters that are now or conceivably intended for consumption, whether they originate from above-ground or subsurface sources.

The Act mandates that all owners or operators of public water systems adhere to these fundamental (health-related) criteria and gives EPA the authority to set minimum standards to safeguard tap water.

The 1996 modifications to the SDWA mandate that while setting these criteria, EPA takes into account a thorough risk and cost evaluation as well as the finest peer-reviewed science.

The attainment of secondary standards is also encouraged by state governments, which may be authorized to implement these EPA regulations.

Answer:

\(V=45396.2\ cm^3\)

Step-by-step explanation:

Given that,

The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.

The tank is filled to 80% capacity with water.

We need to find the water needed for this tank.

The volume of cuboid is given by :

\(V=lbh\)

As it is filled to 80% capacity, so,

\(V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3\)

So, \(45396.2\ cm^3\) of water is needed for this tank.

the probability that both motors from the particular supplier are assigned to the first line is approximately 0.0833 or 8.33%.

To find the probability that both motors from the particular supplier are assigned to the first line, we can consider the total number of possible outcomes and the number of favorable outcomes.

Total Number of Outcomes:

The total number of ways to divide the nine distinct motors equally among the three production lines can be calculated using combinatorics. Since each line receives three motors, we can use the combination formula to determine the total number of outcomes:

Total Number of Outcomes = C(9, 3) * C(6, 3) * C(3, 3)

Number of Favorable Outcomes:

To have both motors from the particular supplier assigned to the first line, we need to select those two motors from the two motors supplied by the particular supplier and one more motor from the remaining seven motors. This can be calculated using the combination formula:

Number of Favorable Outcomes = C(2, 2) * C(7, 1) * C(6, 3) * C(3, 3)

Now, we can calculate the probability by dividing the number of favorable outcomes by the total number of outcomes:

Probability = Number of Favorable Outcomes / Total Number of Outcomes

Substituting the values into the formula:

Probability = (C(2, 2) * C(7, 1) * C(6, 3) * C(3, 3)) / (C(9, 3) * C(6, 3) * C(3, 3))

Simplifying the expression:

Probability = (1 * 7 * 20 * 1) / (84 * 20 * 1)

Probability = 7 / 84

Probability ≈ 0.0833

Therefore, the probability that both motors from the particular supplier are assigned to the first line is approximately 0.0833 or 8.33%.

The statement "Length of 'center' must equal the number of columns of 'x'" is generally false. The length of the 'center' variable does not necessarily need to equal the number of columns of 'x'.

The requirement for the length of 'center' depends on the specific context or purpose of its usage in relation to 'x'. In some cases, 'center' may represent a vector or an array containing the central values or positions of a dataset or matrix. In such cases, the length of 'center' would typically match the dimensionality of the dataset or matrix, which would correspond to the number of rows or columns in 'x'. However, there can be situations where 'center' represents something else entirely, such as a single value or a different set of values unrelated to the dimensions of 'x'.
