Answer: 1,403

Step-by-step explanation: None

Answer:

1403

Step-by-step explanation:

First you find out how many minutes is each episodes at that is 23

Then you multiple 23 by 61 and you get 1403

Step-by-step explanation:

First find 1/4 of 72 runners. To do this divide by 4.

So

72/4=18

Now take 72 and subtract 18 to get 54

Next find 1/3 of 54 runners

54/3=18

Because it is 2/3 you need to multiply 18 by 2

So

18 x 2 = 36

So

54-36=18 runners that finished the race

If needed in fraction form

18/72

Now simplify

9/16 of the runners finished

The original price of the PlayStation 5 is $500 and there is a 30% discount, calculated as $500 x 30/100 = $150. The sale price is $500 - $150 = $350.

The calculation of the sale price of the PlayStation 5 involves finding the amount of the discount first. The original price of the PlayStation 5 is $500. The discount is 30%, which means that 30% of the original price will be taken off. To find the amount of the discount, we multiply the original price by the discount rate (30% or 0.30).

$500 x 0.30 = $150

Next, we subtract the discount from the original price to get the sale price:

$500 - $150 = $350

So, the sale price of the PlayStation 5 is $350.

The sale price of the PlayStation 5 is an important aspect for customers who are looking for a good deal. By knowing the original price and the discount, one can easily find the sale price. This type of calculation is common in retail and commerce, and is used to determine the savings that a customer can make on a particular item during a sale. Understanding these concepts is crucial for consumers to make informed decisions about their purchases, and for businesses to effectively promote their products and attract customers.

The probability that a man will test positive on two successive tests if he has the disease 81%.

In mathematical terms, probability can be represented as the ratio of the number of favorable outcomes to the number of possible outcomes. The formula for probability is as follows:

P(E) = n(E) / n(S)

Where:

P(E) is the probability of event E occurring

n(E) is the number of favorable outcomes for event E

n(S) is the number of possible outcomes in the sample space S

Let's assume the probability of a man testing positive for a disease if he has it is represented by the symbol "P".

If the tests are independent, meaning that the outcome of one test does not affect the outcome of the other, then the probability of a man testing positive on two successive tests can be calculated as the product of the probabilities of each individual test.

Therefore, the probability of a man testing positive on two successive tests if he has the disease is P * P, or P².

If the probability of a man testing positive for a disease if he has it is 90%, represented by P = 0.9, then the probability of him testing positive on two successive tests is 0.9 * 0.9 = 0.81, or 81%.

The equation of the line parallel to 8x+5y=1 passing through the point (1,−3)

is y = (-8/5)x - (7/5).

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line is y = m(1)x + c

Now,

The equation of the line parallel to 8x+5y=1 passes through the point (1, -3).

This means,

8x + 5y = 1

5y = - 8x + 1

y = (-8/5)x + 1/5

This is in the form of y = m(2)x + c

m(2) = (-8/5)

Now,

Since the line is parallel.

m(1) = m(2) = (-8/5)

So,

y = (-8/5)x + c

Now,

(1, -3) = (x, y)

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

c = -3 + 8/5

c = (-15 + 8) / 5

c = -7/5

So,

y = (-8/5)x - (7/5)

The pressure in the tyre when the volume is 140 cubic inches will be 30 pounds.

Boyle's law states that at a constant temperature, the pressure is inversely proportional to the volume. It means that the product of the pressure and the volume will remain constant for the given system.

Given that when air is pumped into an automobile tire, the pressure is inversely proportional to the volume. If the pressure is 35 pounds when the volume is 120 cubic inches.

The pressure will be calculated as:-

P₁V₁ = P₂V₂

( 35 x 120 ) = 140 x P₂

P₂ = ( 35 x 120 ) / 140

P₂ = 30 pounds

Therefore, when the volume is 140 cubic inches, the tire's pressure will be 30 pounds.

The length of the similar polygon is as follows:

TU = 24 Units

Two polygons are similar if their corresponding angles are congruent and their corresponding sides are in proportion.

Therefore, the corresponding angles of the polygons are congruent and the sides are in ratio of each other.

Hence, let's find the side GK and TU as follows:

QRSTU ~ IJKGH

Therefore,

24 / GK = 16  /20

cross multiply

16GK = 480

GK = 480 / 16

GK = 30 Units

By thoroughly reacting a 2.2g zinc nail with an excess of hydrochloric acid, 0.0075 L of hydrogen gas is created.

The force per unit area on an item in the fluid or on the surface of a closed container is measured as fluid pressure. Gravity, acceleration, or forces outside a closed container can all create this pressure. Because a fluid has no fixed structure, its pressure is applied in all directions.

Here,

The reaction between zinc and hydrochloric acid produces hydrogen gas according to the following equation:

Zn + 2HCl -> ZnCl2 + H2

From the equation, we can see that 1 mole of zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of hydrogen gas. The volume of a gas is proportional to the number of moles at constant temperature and pressure, so if we can determine the number of moles of zinc that were reacted, we can calculate the volume of hydrogen produced.

The moles of zinc can be calculated using the molar mass of zinc:

moles = mass / molar mass

moles = 2.2 g / 65.38 g/mol = 0.0337 mol

Since 1 mole of zinc reacts with 2 moles of hydrochloric acid, the number of moles of hydrogen produced is 0.0337 mol * 1 mol H2/1 mol Zn = 0.0337 mol H2.

Finally, the volume of hydrogen produced at standard temperature and pressure (STP) is calculated using the Ideal Gas Law:

PV = nRT

V = nRT / P

V = (0.0337 mol) * (0.08206 L atm / K mol) * (273.15 K) / (1 atm)

V = 0.0075 L
