Answer:

$8421.60

Step-by-step explanation:

First, we need to convert the dimensions of the deck from yards to square yards, since the cost is given per square yard.

The area of the deck is the product of its length and width:

8 yards * 12 yards = 96 square yards

So, the cost to build the deck is:

$87.85/square yard * 96 square yards = $8421.60

Therefore, it cost $8421.60 to build the deck.

The value of x for the right triangles is derived to be x = 1 or x = -2/3 using the trigonometric ratio of tangent for the angles a and b

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

tan a = (x + 2)/x and tan b = 4/(3x - 1) {opposite/adjacent}

(x + 2)/x = 4/(3x - 1)

(3x - 1)(x + 2) = 4x {cross multiplication}

by expansion we have a quadratic equation;

3x² - x - 2 = 0

we can rewrite the equation and factorise as follows;

3x² + 2x - 3x - 2 =0

x(3x + 2) - 1(3x + 2) = 0

(x - 1)(3x + 2) = 0

x = 1 or x = -2/3

Therefore, the value of x for the right triangles is derived to be x = 1 or x = -2/3 using the trigonometric ratio of tangent for the angles a and b.

No graphs were shown to choose from but it would look like a line that has a positive slope, goes throuh y-axis at -2 and slope of 1/2

The slope of the linear equation:

y = -4x + 2/5

is -4.

A general linear equation is written as:

y = ax + b

Where a (the coefficient that multiplies the variable) is called the slope, and b is the y-intercept.

Here the linear equation is:

y = -4x + 2/5

We can see that the coefficient that multiplies the variable is -4, so that is the slope of the line.

(a) There are 81 different sequences of sandwiches are possible

(b) The total number of different (unordered) collections of sandwiches is 3.

First, we need to determine the number of ways the four tuna fish sandwiches can be ordered. Since all four sandwiches are the same, there is only one way to order them. Similarly, there is only one way to order the two chicken sandwiches and the two roast beef sandwiches. For the two people who can choose any sandwich, there are three options for each person, giving a total of 3 x 3 = 9 possible sandwich combinations.

Therefore, the total number of different sequences of sandwiches is:

1 (tuna fish) x 1 (chicken) x 1 (roast beef) x 9 (any sandwich) x 9 (any sandwich) = 81

For part (b), we need to determine the number of different (unordered) collections of sandwiches. We can use combinations to solve this problem. We need to select 10 sandwiches from the total of 10 sandwiches available. Since there are four tuna fish sandwiches, we need to select four of them.

Similarly, we need to select two chicken sandwiches and two roast beef sandwiches. Finally, we need to select two more sandwiches from the remaining three (since two people can choose any sandwich). The number of ways to select these sandwiches is:

The equation for the function is d = (1/10)t + 10.

We have,

Let's call the depth of the water in inches "d" and the time in minutes "t".

We know that the pool starts with a depth of 10 inches, and Ellie is adding water at a rate of 3 inches every 30 minutes.

This means that for every 30 minutes, the depth of the water increases by 3 inches.

To write an equation for this function, we can use the slope-intercept form of a linear equation, where "m" is the slope and "b" is the y-intercept:

d = mt + b

In this case, the slope is the rate of increase in depth per minute, which is 3/30 = 1/10 inches per minute.

The y-intercept is the initial depth of the pool, which is 10 inches.

So the equation for the function is:

d = (1/10)t + 10

This equation tells us that after "x" minutes, the depth of the water in the pool will be:

d = (1/10)x + 10 inches.

Thus,

The equation for the function is d = (1/10)t + 10.

Answer:

(3 houses/acre)(100 acres)(.5) =

150 houses

The remaining land is 50 acres (100-50), and the builder plans to build three houses per acre. So, the number of houses that can be built on this property is (50 x 3) = 150 acres.

First, let's determine how much of the 100-acre plot is left for building houses after setting aside land for the school, playground, roads, drainage ditches, sidewalks, and the strip shopping area with parking and buffer.

1. School and playground: 20% of 100 acres = 0.20 * 100 = 20 acres
2. Roads, drainage ditches, and sidewalks: 15% of 100 acres = 0.15 * 100 = 15 acres
3. Strip shopping area with parking and buffer: 15% of 100 acres = 0.15 * 100 = 15 acres

Now, add up these reserved areas: 20 acres + 15 acres + 15 acres = 50 acres

The builder has set aside 20 acres for the school and playground, 15 acres for roads, drainage ditches, and sidewalks, and another 15 acres for the strip shopping area with parking and buffer. Therefore, the total area that has been allocated is 50 acres (20+15+15).

Subtract the total reserved area from the total plot area to find the area available for building houses: 100 acres - 50 acres = 50 acres

Since the builder plans to build three houses per acre, we can multiply the available area by the number of houses per acre: 50 acres * 3 houses/acre = 150 houses

The builder can build 150 homes on this property.

The volume of one marble is 27 cubic centimeters.

First, let's calculate the initial volume of water in the container. We know that the container is 8 cm long, 9 cm wide, and filled with water to a depth of 6 cm. Therefore, the initial volume of water in the container can be calculated as follows:

Volume of water = length x width x height

= 8 cm x 9 cm x 6 cm

= 432 cm³

Next, we need to find the final volume of water in the container after the 12 marbles were added. We are given that the depth of the water increased from 6 cm to 7.5 cm. Therefore, the final height of the water can be calculated as follows:

Final height of water = 7.5 cm - 6 cm

= 1.5 cm

Now, we can find the final volume of water in the container as follows:

Volume of water = length x width x height

= 8 cm x 9 cm x 1.5 cm

= 108 cm³

The difference between the initial volume of water and the final volume of water is equal to the volume of 12 marbles that were added to the container. Therefore, we can calculate the volume of one marble as follows:

Volume of one marble = (Final volume of water - Initial volume of water) / Number of marbles

= (108 cm³ - 432 cm³) / 12

= 324 cm³ / 12

Answer:

-8 (or) 5 and 5 (or) -8

Step-by-step explanation:

Let one of the numbers = x

Let other number = y

As the sum of two numbers = -3

x + y = -3

x = -3-y

As the the result of multiplication = -40

xy = -40

(-3-y)*y = -40

-3y-y² = -40

-y²-3y+40 = 0

-(y²+3y-40) = 0

-(y+8)(y-5) = 0

(-y-8)(y-5) = 0

-y-8 = 0 (or) y-5 = 0

-y = 8 (or) y = 5

y = -8 (or) y = 5

when y = -8

x = -3-y

x = -3-(-8)

x = -3+8

x = 5

when y = 5

x = -3-y

x = -3-5

x = -8

Sample mean (X) = 6.2 minutes

Sample standard deviation (s) = 1.7 minutes

Sample size (n) = 13

Confidence level = 95%

Since the sample size is less than 30, we will use the t-distribution for calculating the confidence interval.

First, we need to find the t-value for a 95% confidence level with 12 degrees of freedom (n-1).

From the t-distribution table, we find the t-value to be 2.179.

Calculate the margin of error (E) using the formula:

E = t×value × (s/√n)

E = 2.179 × (1.7/√13)

E = 1.027

The confidence interval by adding and subtracting the margin of error from the sample mean:

CI = (X - E, X + E)

CI = (6.2 - 1.182, 6.2 + 1.182)

CI = (5.172, 7.227)
