Mr. Hamstra can travel about 70 miles when his tank is 1/4 full.

The distance a car can go on a given quantity of gasoline is measured as gas mileage, also known as fuel efficiency. By dividing the distance driven by the amount of gasoline used, one may determine gas mileage. For instance, a car's gas mileage is 25 mpg (300/12 = 25) if it can go 300 miles on 12 gallons of petrol. Many variables, including traffic, speed, weather, road gradient, and vehicle maintenance, can have an impact on gas mileage.

Given that, Mr. Hamstra’s car holds 14 2/5 gallons of gas and averages 20 miles per gallon.

Thus, when his tank is 1/4 full, it contains:

1/4 * 14 2/5 = 14 2/5 / 4 = 3 1/2 gallons.

Hence, Mr. Hamstra can travel about 70 miles when his tank is 1/4 full.

The trade discount is $15.75.

A trade discount is a regular reduction from a product's regular, established price. The use of trade discounts allows a company to adjust the final price based on the volume or status of each customer.

It is important to note that trade discounts are not the same as early-payment discounts. (Early-payment discounts of 1% or 2% are typically recorded by the seller in an account such as Sales Discounts and by the buyer in an account such as Purchase Discounts using the periodic inventory method.) Neither the seller nor the buyer keeps a separate account for trade discounts.

We must first determine the product's list price in order to determine the trade discount.

List price: $75 plus $3.75 equals $78.75

As the trade discount rate is 20%, the following discount is offered:

Discount = 0.2 times List price = 0.2 times $78.75 = $15.75

The trade discount is therefore $15.75.

Answer:25

Step-by-step explanation: 25 25 25

The decay of Element X can be modeled by the equation:

N = N0 * (1/2)^(t/t1/2)

where N is the amount of Element X remaining after time t, N0 is the initial amount of Element X, t1/2 is the half-life of Element X, and ^(t/t1/2) denotes exponentiation with base 1/2.

We know that the initial amount of Element X is 470 grams, the half-life is 8 minutes, and we want to find the time it takes for Element X to decay to 10 grams. Let t be the time in minutes.

Then, we can set up the following equation:

10 = 470 * (1/2)^(t/8)

Dividing both sides by 470, we get:

(1/47) = (1/2)^(t/8)

Taking the natural logarithm of both sides, we get:

ln(1/47) = (t/8) * ln(1/2)

Solving for t, we get:

t = -8 * ln(47)/ln(2)

t ≈ 59.3

Therefore, it would take about 59.3 minutes, to the nearest tenth of a minute, for Element X to decay to 10 grams.

Answer:

26

Step-by-step explanation:

(6x + 4) + (4x + 6) = 90

180 - (4x + 6) = (6x + 4) + 90

Rearrange the equation.

180 - (-90) = (6x + 4) + (4x + 6)

270 = 6x + 4 + 4x + 6

270 = 10x + 10

260 = 10x

26 = x

I don't know if this is correct, so I apologize if its wrong.

Answer:

x = 8

Step-by-step explanation:

According to the picture,

These given two angles are complementary. That is, those two angles are added up to 90°.

Therefore,

( 6x + 4 ) + ( 4x + 6 ) = 90

Combine like terms.

6x + 4 + 4x + 6 = 90

10x + 10 = 90

Subtract 10 from both sides.

10x = 90 - 10

10x = 80

Divide both sides by 10.

x = 8

Answer: m∠G = 41°

Step-by-step explanation:

      Opposite angles of parallelograms are congruent. This means that m∠G = m∠E, so we can write an equation using the given information.

Given:

      m∠G = m∠E

Substitue:

      5x - 9 = 3x + 11

Add 9 to both sides of the equation:

      5x = 3x + 20

Subtract 3x from both sides of the equation:

      2x = 20

Divide both sides of the equation by 2:

      x = 10

      Then, we will substitute this value of x back into the expression for m∠G.

5x - 9 = 5(10) - 9 = 50 - 9 = 41°

Answer:

The strip pattern has a vertical axis of symmetry, so a reflection across a vertical line will map the strip pattern onto itself. Therefore, the correct answer is "a reflection across a vertical line."

Step-by-step explanation:

We're given the angle measure to be 46 for No. 8. The length of 1 leg is x and the hypotenuse is 28.

We can use cosine to solve this. Since cosine is adjacent over hypotenuse, we can do cos(46) = x/28. Cross multiply to get cos(46)*28 = x. That solves to be 19.5

Using this principle allows us to solve the other ones. I'll let you figure them out.

TLDR: We can use the definition of trig functions to plug in what we know and place variables where we don't have enough information to find the length of a side.

The exponential function [tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex] determines the amοunt of substance after 36 years to be 0.2 grams.

The fοrmula for an exponential functiοn is [tex]f(x) = a^x[/tex], where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The amοunt of a radioactive substance left after a certain number of half-lives can be calculated using the expοnential equation formula -

[tex]A = A_0 \times \frac{1}{2}^{\frac{t}{T}}[/tex]

where -

A0 is the initial amοunt of the substance

A is the amοunt of the substance remaining after t years

T is the half-life οf the substance

In this case, the half-life is 8 years, sο T = 8.

We want tο know how much of the original 3.2 grams of the substance wοuld be left after 36 years, so t = 36.

We can plug these values intο the formula to get -

[tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex]

A ≈ 0.2 grams

Therefοre, after 36 years, only about 0.2 grams of the original 3.2 grams of the substance wοuld be left.

The equation that best mοdels this situation is -

[tex]A = 3.3 \times \frac{1}{2}^{\frac{t}{8}}[/tex]

where A represents the amοunt of the substance remaining after t years, in grams.

Therefοre, the equation is [tex]A = 3.2 \times \frac{1}{2}^{\frac{36}{8}}[/tex].

In business and economics, cost, revenue, and profit are key concepts that relate to the financial aspects of a business.

Cost refers to the expenses incurred by a business in order to produce, sell or distribute its products or services. This includes direct costs, such as the cost of raw materials, labor and overhead expenses, as well as indirect costs, such as marketing and administrative expenses.

Revenue, on the other hand, refers to the income generated by a business through the sale of its products or services. Revenue can be calculated by multiplying the price of a product or service by the number of units sold.

Profit is the difference between revenue and cost, and is a measure of how much money a business earns after all of its expenses are paid. A business earns a profit when its revenue exceeds its total costs, including both fixed and variable costs.

Profit can be further broken down into gross profit and net profit. Gross profit is the difference between revenue and the direct cost of producing or delivering a product or service. Net profit, on the other hand, is the profit that remains after all expenses, including indirect costs, taxes and interest payments, have been deducted from revenue.

In summary, cost refers to the expenses incurred by a business, revenue refers to the income generated by the sale of products or services, and profit is the difference between revenue and cost, indicating how much money a business earns after all expenses are paid.

Step-by-step explanation:

The unit rate is 12 computers per day (36/3 = 12; 48/4 = 12; 60/5 = 12). This means that the factory produces 12 computers per day.

Computers are electronic devices that are used to store, process, and output data. They are used to perform a variety of tasks, from simple calculations to complex research projects. Computers consist of hardware, such as processors, memory, and storage devices, and software, which provides instructions for the hardware to follow.

The unit rate is the number of units produced per unit of time. To calculate the unit rate of computers per day using the graph, divide the number of computers produced by the number of days. Using the graph, 36 computers are produced in 3 days, 48 computers are produced in 4 days, and 60 computers are produced in 5 days.

Therefore, the unit rate is 12 computers per day (36/3 = 12; 48/4 = 12; 60/5 = 12). This means that the factory produces 12 computers per day. The graph produced shows a proportional relationship between the number of computers produced at a factory per day.
