Answer: The correct answer will be $1,220 in the account after four years.

Step-by-step explanation: For this problem we will use the "Simple Interest" equation to find the amount of interest you will earn after 4 years.

First, convert 5.5% to a decimal, 0.055.

I, interest = 1000 x 0.055 x 4

I = $220

Now add the interest to the total amount of money originally in the account.

1000 + 220 = $1,220

Final answer:

The amount in the account after four years, with continuous compound interest at a rate of 5.5%, is approximately $1246. Therefore, after four years, the amount in the account will be closest to option (b) $1,246.

Explanation:

To calculate the amount in the account after four years, we can use the formula for continuous compound interest: A = P  [tex]e^{(rt)}[/tex], where A is the final amount, P is the initial principal, e is the mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time in years.

In this case, P = $1000, r = 5.5% = 0.055, and t = 4. Plugging these values into the formula, we have:

A = $1000 × [tex]e^{(0.055 \times 4)}[/tex]

A = $1000 × [tex]e^{0.22[/tex]

A ≈ $1000 × 1.246

Therefore, the amount in the account after four years is approximately $1246.

Answer:

The maximum number of quarters that he could have is 13

Step-by-step explanation:

Let x represent the number of quarters he could have. If he has 10 dimes and has at least 20 coins, then

→ x + 10 >= 20

→ x >= 10    (1)

His coins worth at most $4.25. Also, it is known that 1 dollar is equal to 100 cents, 1 dime is equal to 10 cents and 1 quarter is equal to 25 cents.

→ (x * 25) + (10 * 10)  <= (4.25 * 100)

→ 25x  + 100 <= 425

→ 25x <= 325

→ x <= 13  (2)

If we combine the equation 1 and 2:

10 <= x <= 13

The maximum value of x is 13

Given:

Given that the radius of the cone is 2 inches.

The height of the cone is 4 inches.

We need to determine the volume of the cone.

Volume of the cone:

The volume of the cone can be determined using the formula,

[tex]V=\frac{1}{3} \pi r^2 h[/tex]

where r is the radius of the cone and h is the height of the cone.

Substituting r = 2 and h = 4 in the above formula, we get;

[tex]V=\frac{1}{3} (3.14) (2)^2 (4)[/tex]

[tex]V=\frac{1}{3} (3.14) (4) (4)[/tex]

[tex]V=\frac{1}{3}(50.24)[/tex]

[tex]V=16.75[/tex]

Thus, the volume of the cone is 16.75 cubic inches.

Answer:

2.71828

Step-by-step explanation:

In this question, we are asked to give the approximate value of the irrational number e.

We should understand that just like Pi, which is the ratio of the circumference of a circle to the diameter, we have the number called e. It is also a consistent like Pi and has an approximate value of 2.71828.

What does it mean when it is called irrational? it is an irrational number because it doesn’t have an exact fraction which is the ratio of two numbers and thus it has a non-ending list of numbers after the decimal point.

Final answer:

The irrational number e, also known as Euler's number, is approximately 2.71828 when rounded to five decimal places. It is crucial in mathematics, particularly calculus.

Explanation:

The question asks for the approximate value of the irrational number e rounded to five decimal places. The number e is a fundamental constant in mathematics, often referred to as Euler's number, which is approximately equal to 2.71828 when rounded to five decimal places.

This number plays a crucial role in various branches of mathematics, especially in calculus, relating to the rate of growth or decay in natural phenomena.

Answer:

x=2.25

Step-by-step explanation:

Let's break this down:

Saying "y=", is just like saying "0=", so we can say that;

0=4x-9

We need to isolate the variable, and to do that we should add 9 to both sides and cancel it out.

9=4x

Now we need to eliminate the coefficient by dividing both sides by four

[tex]9/4=4x/4[/tex]

Which cancels out four, giving us

2.25=x

Given:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

Area of the triangle:

The area of the triangle can be determined using the formula,

[tex]A=\frac{1}{2} a b \ sin \ c[/tex]

Substituting a = 10, b = 13 and ∠C = 105°, we get;

[tex]A=\frac{1}{2}(10)(13) \ sin \ 105[/tex]

Simplifying, we get;

[tex]A=\frac{1}{2}(10)(13)(0.966)[/tex]

[tex]A=\frac{1}{2}(125.58)[/tex]

[tex]A=62.79 \ cm^2[/tex]

Rounding off to 1 decimal place, we have;

[tex]A=62.8 \ cm^2[/tex]

Thus, the area of the triangle is 62.8 cm²

The area of the triangle is 65 square centimeters when rounded to one decimal place.

To find the area of a triangle, you can use the formula:

[tex]Area = (\frac{1}{2} ) \times base \times height[/tex]

In this case, you have a base of 13 cm and a height of 10 cm. Plug these values into the formula:

[tex]Area =(\frac{1}{2} ) \times 13 cm \times 10 cm[/tex]

[tex]Area = (\frac{1}{2}) \times 130 cm^2[/tex]

Now, calculate the area:

[tex]Area = 65 cm^2[/tex]

So, the area of the triangle is 65 square centimeters when rounded to one decimal place.

Answer:

They'll build 66 cars in those conditions.

Step-by-step explanation:

In this case we can use a compounded rule of three to solve the problem. We need to set it up as shown bellow:

160 workers -> 32 cars -> 2 hours

220 workers -> x cars -> 3 hours

If the number of workers rise, then we expect the number of cars to rise aswel, so they're directly proportional. If the number of hours worked increase we can expect the number of cars to increase aswell, so they're directly proportional. We can now set the fractions:

(160*2)/(220*3) = 32/x

320/660 = 32/x

x = (32*660/320) = 66 cars

They'll build 66 cars in those conditions.

Final answer:

To find the number of cars that 220 workers can produce in 3 hours, we can use the joint variation equation and the given information. By solving for the constant of variation, we can substitute the new values to find the answer.

Explanation:

To solve this problem, we can set up a joint variation equation:

cars = k * workers * time

Given that 160 workers can produce 32 cars in 2 hours, we can substitute these values into the equation:

32 = k * 160 * 2

Solving for k, we find that k = 0.1.

Now, we can use this value of k to find the number of cars that 220 workers can produce in 3 hours:

cars = 0.1 * 220 * 3

cars = 66

Therefore, 220 workers can produce 66 cars in 3 hours.

Final answer:

Susie was 20 meters behind Andy when he reached the finish line in the 100-meter race.

Explanation:

To determine how many meters Susie was behind Andy at the moment Andy reached the finish line during the 100-meter race, let's consider the information given:

Andy finished the race.

Blaise was 10 meters behind Andy at that moment.

Susie was 10 meters behind Blaise when Blaise finished the race.

When Blaise reached the finish line, Andy would have already finished since Blaise was behind by 10 meters. However, at the moment Andy finished, Susie was also behind Blaise, who was 10 meters from finishing. Hence, Susie was 10 meters (the distance Blaise was behind Andy) + 10 meters (the distance Susie was behind Blaise at her finish) = 20 meters behind Andy when he finished the race.

In conclusion, Susie was 20 meters behind Andy when Andy reached the finish line.
