The volume of larger solid represented by b is 3125.

The scale factor of two solids will be equal to the following formula -

volume of solid a/volume of solid b = solid a³/solid b³

Keep the values in formula to find the volume of solid b

200/ volume of solid b = 2³/5³

Rewriting the equation according to volume of solid b

Volume of solid b = 5³ × 200/2³

Performing multiplication with cube of 5

Volume of solid b = 125 × 200/8

Volume of solid b = 25000/8

Performing division on Right Hand Side of the equation

Volume of solid b = 3125

as you can see, yes, really easy.

what was the problem ? do you need any further explanation ?

The given exponential function represents decay since the base (0.13) is less than 1. And the percentage decrease of 91.68%.

The percentage rate of the decrease can be determined by taking the base and subtracting it from 1 and then multiplying the result by 100. Mathematically, this can be expressed as (1 - 0.13)*100 = 87%. To illustrate this mathematically, let's assume that the initial value of y is 100. We can then calculate the value of y after one time period (t) as follows: y = 64(0.13)t.

Plugging in t = 1, we get y = 64(0.13) = 8.32. This means that the value of y has decreased by (100 - 8.32) = 91.68, or a decrease of 91.68%. Dividing this by the initial value of 100 gives us a percentage decrease of 91.68%/100 = 0.9168 or 91.68%.

Answer:

Step-by-step explanation:

d

With the value tanθ = 4/3 on the interval (π, 3π/2), using trigonometric identities sin 2θ = 24/25 , cos 2θ = -7/25 , tan 2θ = -8/7.

First, we'll find sin 2θ:

sin 2θ = 2sinθcosθ

We can use the identity tanθ = sinθ/cosθ to find sinθ and cosθ:

sinθ = 4/5 and cosθ = 3/5

So,

sin 2θ = 2(4/5)(3/5) = 24/25

Next, we'll find cos 2θ:

cos 2θ = cos^2θ - sin^2θ = 1 - 2sin^2θ

Using the values of sinθ and cosθ that we found earlier:

cos 2θ = 1 - 2(4/5)^2 = 1 - 32/25 = -7/25

Finally, we'll find tan 2θ:

tan 2θ = (2tanθ)/(1 - tan^2θ)

Using the value of tanθ that we were given:

tan 2θ = (2(4/3))/(1 - (4/3)^2) = (8/3)/(-7/9) = -8/7

So, the values of sin 2θ, cos 2θ, and tan 2θ are:

sin 2θ = 24/25

cos 2θ = -7/25

tan 2θ = -8/7

The original price of the pair of jeans is equals to the $120.

We Jodi wants to buy a pair of jeans.

The purchase price of pair of jeans = $90

Discount on price of jeans = 75%

Let the original price of pair of jeans be equal to "$x". Percent is an important concept of mathematics. It is a number or ratio of fraction of hundred. It is denoted by symbol %. The formula is

% = ( part /whole )×100

Here, it is said that the price of pair of jeans, $90, is only 75% of the original price. So, we can write it as the following way 75% of x = 90

=> (75/100) of x = 90

=> (75/100) × x = 90

=> x = 90× 100/75

=> x = 9000/75

=> x = 120

42 feet is the length of the guy wire.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that a pole 10 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground.

After placing the pole, Liam measures the distance from the pole to the stake and from the pole to the tower.

We have to find the length of the guy wire

Let the required distance is x and the height of the tower is t.  

Use similar triangle ratios to find the value of t:  

t / 10 = (9 + 3) / 3

t / 10 = 4

t = 40 feet

Use Pythagorean to find the value of x:  

x² = 40² + (9 + 3)²

x² = 1600 + 144

x² = 1744

x = √1744

x = 42 feet

Hence, 42 feet is the length of the guy wire.

The side lengths x and y are √( 50² - y²) and √50² - x² respectively.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

In a right angle triangle, the length of one side can be determined using the Pythagorean theorem:

x² + y² = hypotenuse²

In the given triangle the length of hypotenuse is 50 cm

x² = 50² - y²

The experimental probability of getting an odd number on the next toss is 51.3%.

Probability is a measure of the likelihood of an event occurring. In the case of the six-sided number cube, the theoretical probability of getting an odd number on any one roll is 3 out of 6, or 1/2, or 50%. However, this is a theoretical value and may not match the actual results obtained from a set of experiments.

The experimental probability of an event is calculated by observing the actual results of a series of trials and comparing it to the number of possible outcomes. In this case, the number cube was tossed 150 times and the results were recorded in the table. The frequency of the odd numbers (1, 3, and 5) was found to be 77.

The experimental probability of getting an odd number on the next toss can be calculated by dividing the frequency of the odd numbers by the total number of tosses, which is 150. 77/150 = 0.513 or 51.3%.

Therefore, the experimental probability of getting an odd number on the next toss of the six-sided number cube is 51.3%.

The answers for the asked probabilities are a) 1/6, b) 5/36, c) 1/36 and d) A and B events are not independent.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, Antonia rolls a pair of fair six-sided dice. A is the event that the first die lands on 5 and B is the event that the sum of the two dice is 6.

Probability = possible outcomes / favorable outcomes

Suppose that Antonia rolls a pair of fair six-sided dice.

All possible outcomes are:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

(36 outcomes in total)

a) A = the first die lands on 5

Favorable outcomes:

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6 outcomes)

Therefore, the probability that the first die lands on 5 = P(A) = 6/36 = 1/6

b) B = the sum of the two dice is 6

Favorable outcomes:

(1, 5), (2, 4), (3, 3), (4, 2), (5, 1) = (5 outcomes)

Therefore, the probability that the sum of the two dice is P(B) = 6 = 5/36

c) A∩B = the first die lands on 5 and the two dice add up to 6

Favorable outcomes:

(5, 1) = 1 outcome

Therefore, the probability that the first die lands on 5 and the two dice add up to6 = P(A∩B) = 1/36

d) Two events are independent when;

P(A∩B) = P(A) · P(B)

Since,

1/36 ≠ 5/36 · 1/36

Therefore, A and B events are not independent.

Hence, the answers for the asked probabilities are a) 1/6, b) 5/36, c) 1/36 and d) A and B events are not independent.

It is important to use a device like a random number table in a simulation because Option A Chance plays a part in the process being simulated.

In simulations, a random number table is used to incorporate the element of chance into the process being modeled. The reason this is important is that many real-world processes involve uncertainty and randomness, and to accurately simulate these processes, it is necessary to include these elements.

For example, in simulating the stock market, stock prices can be modeled as random variables, because they are influenced by a variety of unpredictable factors such as changes in interest rates, company earnings, geopolitical events, and investor sentiment. To simulate this process, a random number table can be used to generate random numbers that represent these unpredictable factors.

By using a random number table, the simulation can model the uncertainty and randomness inherent in the real-world process, which makes the simulation more accurate and realistic. This is why it is important to use a device like a random number table in a simulation when chance plays a part in the process being simulated.

Answer:

a. To find the annual net income, subtract the annual expenses from the annual rental income.

The annual rental income = $750 * 12 months = $9,000

So, the annual net income = $9,000 - $6,890 = $2,110

b. To find the annual yield, divide the annual net income by the investment cost (the down payment) and multiply by 100 to get the answer as a percentage.

The annual yield = ($2,110 / $28,500) * 100 = 7.41%

c. To find the monthly rent required to get a yield of 90%, divide the investment cost by the desired yield and divide by 12 to get the monthly rent.

The investment cost = $28,500

The desired yield = 0.90

Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.
