The area of this hexagon is 374.4 in².

The area of the hexagon is calculated by applying the following formula.

total area of the regular hexagon = 6 x area of one face

Area of one face = ¹/₂bh

where;

Area of one face = ¹/₂ x ( 12 in ) x ( 10.4 in )

Area of one face = 62.4 in²

Total area of the hexagon = ( 6 ) x ( 62.4 in² ) = 374.4 in²

So, the probability of selecting a menu from a Japanese restaurant is 4/18, which can also be simplified as 2/9.

The probability of selecting a Japanese restaurant menu from Zach's collection of 18 menus is found by taking the number of Japanese restaurant menus (4) and dividing it by the total number of menus in the collection (18). This can be written mathematically as:

p(japanese) = 4/18

So the probability of selecting a menu from a Japanese restaurant is 4/18, which can also be simplified as 2/9.

In other words, if Zach selects a menu at random from his collection, there is a 2/9 chance that it will be from a Japanese restaurant.

The speed of the current is 1 mile per hour.

To calculate we can start by using the formula: distance = speed x time.

Let's call the speed of the current "c" and the speed of Sarah's rowing "r".

When Sarah rows down the river with the current, her speed is the sum of her rowing speed and the current speed: distance = (r + c) * time

When she rows back against the current, her speed is the difference between her rowing speed and the current speed: distance = (r - c) * time

We know that the distance is four miles in both cases, and the time is one hour and two hours respectively.

So we can set up the following two equations:

(r + c) * 1 = 4

(r - c) * 2 = 4

Solving the first equation:

r + c = 4

Solving the second equation:

r - c = 2

Adding the two equations:

r = 3

We know that Sarah is rowing at a constant speed, so we can substitute this value back into one of the original equations:

(3 + c) * 1 = 4

c = 1

So the speed of the current is 1 mile per hour.

The sum of numbers at B, C, D, E and F is 110.5

Since B, C, D, E, and F divide the segment AG into 6 equal pieces, each piece has a length of (59-13)/6 = 6.5.

Therefore, the numbers at B, C, D, E, and F are located at 13 + 6.5, 13 + 6.52, 13 + 6.53, 13 + 6.54, and 13 + 6.55 respectively.

The sum of the numbers at B, C, D, E and F is (13 + 6.5) + (13 + 6.52) + (13 + 6.53) + (13 + 6.54) + (13 + 6.55)

She reportedly invested $6600 at 3% and $3400 at 2.5%, according to the statement.

Investing is a smart way to put your money to work and could make you richer. If you make smart investing choices, your money may increase in value as outpace inflation. The major factors contributing to investment's increased growth potential are the possibility of compounding and the trade-off amongst risk and return.

Simple interest is calculated as follows: deposit amount multiplied by time and interest rate.

Let "a" represent the money placed in the account earning 3% interest.

Let's use the symbol to represent the amount deposited into the account earning 2.5% interest (10,000 - a)

a * 0.03 plus (10,000 - a) * 0.025 = 283

0.03a + 250 - 0,025a = 283

Collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33

a = $ 6600

Using the trigonometric ratios the correct option is option a) 4.98.

We have a known hypotenuse, but an unknown opposite side. Use the sine ratio to tie the two together to be able to solve for x.

Trigonometric ratios are a set of ratios that relate the angles of a right triangle to the lengths of its sides. The most commonly used trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively.

These ratios can be used to find missing side lengths or angle measures in a right triangle, and they have many applications in mathematics, physics, engineering, and other fields.

sin(angle) = opposite/hypotenuse

sin(50) = x/6.5

6.5*sin(50) = x

x = 6.5*sin(50)

The equation to determine how many bags Trisha brought is: T = 180 - (4 + 6)

We know that the total number of clementines is 180, Sal brought 4 bags and Joe brought 6. To determine how many bags Trisha brought, we need to determine the total number of bags that Sal and Joe brought together. We can do this by combining the two numbers together (4 + 6). This will give us a total of 10 bags. To determine how many bags Trisha brought, we need to subtract the total number of bags that Sal and Joe brought (10) from the total number of clementines (180). This gives us an answer of 170. This means that Trisha brought 170 clementines, or 7 bags. Therefore, the equation to determine how many bags Trisha brought is: T = 180 - (4 + 6).

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.

The probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13

In the given question, suppose that you draw a card from a standard deck of cards.

We have to find the probability that the card is a face card (i.e., a jack, queen, or king) or a heart.

As we know that in a deck of cards have total 52 cards.

In which 26 cards are in heart shape.

Every different type of card have 3 face cards and have total four different type of cards. That means there are total 12 face cards.

In 26 cards of heart have total 6 face cards.

So, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart

P = (Total face cards + total heart shape card - 6 face cards)/Total cards in a deck

P = (12 + 26 - 6)/52

P = (38 - 6)/52

P = 32/52

P = 8/13

Hence, the probability that the card is a face card (i.e., a jack, queen, or king) or a heart is 8/13.

The unit rate of the relationship between the amount of water pumped and time is the amount of water pumped in one minute for 14 hours.

To calculate unit price, you need to divide the first term (quantity) by the second term (unit). The resulting value is the unit price.

For example, if you want to calculate the unit price for a bag of 4 $3 apples, divide the total cost ($3) by the number of apples (4).

$3 / 4 apples = $0.75 / apple

In this example, the unit price is $0.75 per apple. So the price per apple is $0.75.

Given by the equation:

The unit rate of water pumped versus time is the amount of water pumped in one minute, so:

28/2=14

That means 14 gallons of water is being pumped every minute.

Now you can calculate the water pumped in 3/2 minutes like this

14*3/2=21

So in total, water pumped in 12 minutes plus 3/2 minutes gives water pumped in 15/2 minutes.
