Step-by-step explanation:

for the each year, the interest is increased by 2%,

so after 1 year, earned interest is 2% of $400

=2/100 × 400=$8

so the earned balance is $(400+8)=$408

so after 2 year, earned interest is 2% of $408

=2/100 × 408=$8.16

so the earned balance is $(408+8.16)=$416.16

after 3 year, earned interest is 2% of $416.16

=2/100 × 416.16=$8.32

so the earned balance is $(416.16+8.32)=$424.48

after 4 year, earned interest is 2% of $424.48

=2/100 × 424.48=$8.48

so the earned balance is $(424.48+8.48)=$480.48

after 5 year, earned interest is 2% of $480.48

=2/100 × 480.48=$9.6

so the earned balance is $(480.48+9.6)=$490.08

after 6 year, earned interest is 2% of $490.08

=2/100 × 490.08=$9.8

so the earned balance is $(490.08+9.8)=$499.88

therefore the interest earned after 6 years is

$(8+8.16+8.32+8.48+9.6+9.8)=$52.36

and the balance after 6 years is $499.88

------------------------

3+2+4 (sum of all marbles red+Blue+Yellow)          

simplfy

3 /3    

----   =1/3

9 /3            

To find out the theoretical probability of drawing a red marble, divide the total number of red marbles (3) by the total number of marbles (9). Therefore, the theoretical probability is 1/3.

The subject of your question falls under the branch of Mathematics and it's about a concept known as theoretical probability. In this case, the total number of marbles in the bag is 3 red + 2 blue + 4 yellow = 9 marbles. The probability of drawing a red marble from the bag is calculated by dividing the number of red marbles by the total number of marbles. Therefore, the theoretical probability of pulling a red marble is 3/9 which simplifies to 1/3, meaning there is a one in three chance of drawing a red marble.

5 feet 6 inches is equal to ((5*12)+6) inches, which is equal to 66 inches since 5*12=60 and 60+6=66

2 feet 9 inches is equal to ((2*12)+9) inches, which is equal to 33 inches since 2*12=24 and 24+9=33

Since 66 and 33 are the length and width (there isn't any specific order as to which measurement is the length or width) and the question is asking for square inches,(which is the area) so what needs to be done next is 66*33, which equals 2178, the square inches of plastic needed is 2718 square inches.

I couldn't keep the answer in the format of _ft _in because they are asking for the area in inches, and I don't think it would be smart to convert inches to decimal values of feet for reasons I won't talk about.

So yeah, your answer is 2178 square inches of plastic.

given,

Final answer:

The polynomial y^3 - y^2 + y + 3 divided by y + 1 results in a quotient of y^2 - y + 2, with a remainder of 1. The complete division statement is (y^3 - y^2 + y + 3) / (y + 1) = y^2 - y + 2 + 1/(y + 1).

Explanation:

To divide the polynomial y^3 - y^2 + y + 3 by y + 1, we use polynomial long division. First, divide y^3 by y to get y^2, subtract the result from the polynomial, and bring down the next term. Repeating this process gives us the following steps:

Divide y^3 by y to get y^2. Multiply y + 1 by y^2 and subtract from the original polynomial.

Bring down the next term, which is y, and divide -1 by y to get -1. Multiply y + 1 by -1 and subtract from the result of the first step.

Bring down the last term, which is 3, and divide 2 by y to get 2. Multiply y + 1 by 2 and subtract to get the remainder.

The final quotient of this division is y^2 - y + 2, and the remainder is 1.

The result of the division is y^2 - y + 2 with a remainder of 1. To express this as a complete division statement, we write:

(y^3 - y^2 + y + 3) ÷ (y + 1) = y^2 - y + 2 + 1/(y + 1)

The given quadratic equation 2x² + 8x - 1 = 0 can be rearranged as (x + 2)² = 4.5 through the method of completing the square. Taking the square root of both sides gives two solutions for x: x = -2 + √4.5 and x = -2 - √4.5, when rounded to two decimal places.

To solve the equation 2x² + 8x - 1 = 0 by "completing the square", we first divide everything by the coefficient of x², in this case 2, to make the equation look like x² + 4x - 0.5 = 0. The coefficient of x now becomes 4.

We then take half of this coefficient, square it and add it to both sides of the equation. Half of 4 is 2, and squaring it gives us 4. So the equation now reads as x² + 4x + 4 = 4 + 0.5 which simplifies to x² + 4x + 4 = 4.5.

This equation can be further simplified by realizing that (x + 2)² = x² + 4x + 4, thus we have (x + 2)² = 4.5. Taking the square root of both sides finally gives us x = -2 ± √4.5, giving us two solutions for x to two decimal places, that are x = -2 + √4.5, and x = -2 - √4.5.

[tex]3s=6300[/tex]

Number of steps in one mile for Gustave =2100

Step-by-step explanation:

Given : Gustave measured his pace and determined that for him, s steps make up one mile.

1 mile = s steps  (1)

One day Gustave walked 6300 steps, which was 3 miles.

i.e. 3 miles = 6300 steps (2)

Using (2), the number f steps in 3 steps will be :_

3 miles = 3s steps                (3)

From (2) and (3), we have

[tex]3s=6300[/tex]

Dividing both sides by 3 , we get

[tex]s=\dfrac{6300}{3}=2100[/tex]

Hence, the number of steps in one mile for Gustave =2100

Gustave takes 189 steps to walk one mile. We derived this by dividing the total steps, 63,000, by the distance in miles, 333. The equation used was 63000 = s * 333.

To determine how many steps are in one mile for Gustave, we start with the information provided:

Step 1: Write the Equation

We can write the equation as:

63000 = s * 333

Step 2: Solve for s

To find out how many steps make up one mile, we solve for s by dividing both sides of the equation by 333:

s = 63000 / 333

Step 3: Calculate the Value

When we divide 63,000 by 333, we get:

s = 189

This means that Gustave takes 189 steps to walk one mile.

Example Calculation

Since 63,000 steps equal 333 miles, and dividing both 63,000 steps by 333 miles gives us the number of steps per mile:

189 steps per mile.

In conclusion, Gustave takes 189 steps to walk one mile. This equation and process help us determine the number of steps per mile based on the given total steps and distance covered.

Answer:

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Explanation:

We are given that:

Erin planted t tomato plants

Leo planted 5 fewer tomato plants than Erin, this means that:

Leo planted = t - 5 tomato plants

Fillip planted 10 fewer tomato plants than Erin, this means that:

Fillip planted = t - 10 tomato plants

Now, we want to find the total number of tomato plants

This means that we will add the number of plants planted by Erin, Leo and Fillip

Therefore:

Total number of plants = t + t - 5 + t - 10

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Hope this helps :)

Final answer:

The expression that represents the total number of tomato plants Erin, Leo, and Filipe planted is 3t - 15, where t is the number of plants Erin planted.

Explanation:

If Erin planted t tomato plants, then we can express the number of tomato plants Leo and Filipe planted using algebraic expressions that are based on this initial quantity. Leo planted 5 fewer tomato plants than Erin, so we can describe the number of plants Leo planted as t - 5. Similarly, Filipe planted 10 fewer tomato plants than Erin, and his number can be represented by t - 10.

To find the total number of tomato plants all three of them planted together, you would add these expressions:

Total number of plants = Erin's plants + Leo's plants + Filipe's plants

Total = t + (t - 5) + (t - 10)

Simplify the expression by combining like terms:

Total = t + t - 5 + t - 10

Total = 3t - 15

So the expression that represents the total number of tomato plants Erin, Leo, and Filipe planted in all is 3t - 15.

Area = base * height

Area = 15 * 8 = 120 square centimeters

What if you rotate a plane figure around a straight line called the axis? Well, in doing so, you will get what in mathematics is called a solid of revolution, which is a solid figure. In this case, we have a triangle with a side matching the axis and this side. The solid that result when rotating that triangle is a cone. The side that matches the axis is the height of the cone while the side perpendicular to the axis is the radius of the base of the cone. The rotation is performed by the hypotenuse of the triangle (a straight line) through the origin and by an angle of 360 degrees.

Answer:

1.69 ft (approx.)

Step-by-step explanation:

Formula for Volume of cylinder: pi x radius squared x height

Plug in 108 for volume, 3.14 for pi and 12 for height:

108 = 3.14 x r squared x 12

Multiply 3.14 and 12

108 = 37.68 x r squared

Divide both sides by 37.68

2.87 = r squared

"Unsquare" both sides (square root)

1.69 ft. = radius (approximate answer, rounded to nearest hundredth)

Answer:

1.69 ft

Step-by-step explanation:

V = πr²h formula  of a cylinder.

Volume = 108 ft

Height = 12 ft

Radius = r

V = πr²h

108 ft = 22/7 × r² × 12 ft

π = 22/7 or 3.14

108 ft = 264/7r²

108 ft  = 37.71r²

divide both sides by 37.71

108 ft/37.71 =r²

2.86 ft = r²

square root both side

√2.86 ft = √r²

the square cancels the square root

1.69 ft.

                                 To check

V = πr²h

108 = 22/7 × (1.69)² 12

108 = 22/7 × 2.8561 × 12

108 = 107.61≈108

108 ft = 108 ft.

D. Events E and B are independent.

Step-by-step explanation:

It can be determined that Events E and B are independent. The correct answer is: D.

To determine independence between events, we can use the formula:

[tex]\[ P(A \cap B) = P(A) \times P(B) \][/tex]

Let's check for events D and A:

[tex]\[ P(D \cap A) = 0.2 \][/tex]

[tex]\[ P(D) \times P(A) = 0.5 \times 0.2 = 0.1 \][/tex]

Since [tex]\(0.2 \neq 0.1\),[/tex] events D and A are not independent.

Checking for events D and B:

[tex]\[ P(D \cap B) = 0.3 \][/tex]

[tex]\[ P(D) \times P(B) = 0.5 \times 0.3 = 0.15 \][/tex]

Since [tex]\(0.3 = 0.15\)[/tex], events D and B are independent.

Similarly, events A and B:

[tex]\[ P(A \cap B) = 0.15 \][/tex]

[tex]\[ P(A) \times P(B) = 0.2 \times 0.5 = 0.1 \][/tex]

Since [tex]\(0.15 \neq 0.1\)[/tex],events A and B are not independent.

For events E and B:

[tex]\[ P(E \cap B) = 0.15 \][/tex]

[tex]\[ P(E) \times P(B) = 0.3 \times 0.5 = 0.15 \][/tex]

Since [tex]\(0.15 = 0.15\)[/tex], events E and B are independent.

Therefore, the correct answer is: D. Events E and B are independent.

Answer:

Final answer:

The exact value of sin 30 degrees is 0.5, and this is derived from the special 30-60-90 triangle.

Explanation:

The value of sin 30 degrees is 0.5.

This can be determined using the unit circle or by using the trigonometric function of 30 degrees.

When we evaluate sin 30 degrees, we can look at the special right triangle with angles 30-60-90 where the ratio of the opposite to the hypotenuse in a 30-degree angle is 1/2. In this triangle, the side opposite to the 30-degree angle is half the length of the hypotenuse. Therefore, sin 30 degrees is equal to 1/2 or 0.5.
