To find the area of a parallelogram in the coordinate plane, we need to determine the base and the height of the parallelogram.

Using the given coordinates, we can find the length of one side of the parallelogram as the distance between points A and B.

The length of AB = sqrt((6 - 7)^2 + (5 - 5)^2) = sqrt((-1)^2 + 0^2) = sqrt(1) = 1

The height of the parallelogram can be found as the distance between point D and the line passing through points A and B. We can use the formula for the distance between a point and a line to find the perpendicular distance.

The equation of the line passing through A and B can be found using the point-slope form:

y - 5 = (5 - 5)/(7 - 6) * (x - 7)

y - 5 = 0 * (x - 7)

y - 5 = 0

y = 5

The perpendicular distance from point D(-9, -2) to the line y = 5 is the difference in their y-coordinates:

Perpendicular distance = |-2 - 5| = 7

Now, we have the base length AB = 1 and the height = 7.

The area of the parallelogram is given by the formula: Area = base * height.

Area = 1 * 7 = 7 square units.

Check the picture below.

[tex]\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h~~=height\\ a,b=\stackrel{parallel~sides}{bases~\hfill }\\[-0.5em] \hrulefill\\ a=1\\ b=13\\ h=7 \end{cases}\implies A=\cfrac{7(1+13)}{2}\implies A=49[/tex]

The required angle is 24.5°.

Given is a right triangle with perpendicular side 16 and the base = 35 we need to find an acute angle in it,

To find the acute angle in a right triangle given the lengths of the perpendicular side and the base, you can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the perpendicular side to the length of the base side.

In this case, the perpendicular side is 16 and the base is 35.

Let's denote the acute angle as θ.

Using the tangent function, we can set up the equation:

tan(θ) = perpendicular side / base

tan(θ) = 16 / 35

To find the value of θ, we can take the inverse tangent of both sides:

θ = tan⁻¹(16 / 35)

θ = 24.5°

Hence the required angle is 24.5°.

Answer:

(a) - [tex]y=-2x+18[/tex]

(b) - [tex]y=\frac{1}{2} x-\frac{9}{2}[/tex]

Step-by-step explanation:

Given the equation of a line, which we'll call line 1, find the following.

(a) - The equation of a line, which we'll call line 2, that is parallel to line 1 and travels through the point (9,0)

(b) - The equation of a line, which we'll call line 3, that is perpendicular to line 1 and travels through the point (9,0)

Given:

[tex]3y+6x=-6[/tex]

(1) - Write the equation of line 1 in slope-intercept form

[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Slope-Intercept Form:}}\\y=mx+b\\\bullet \ m \ \text{is the slope of the line}\\\bullet \ b \ \text{is the y-intercept of the line}\end{array}\right}[/tex]

[tex]3y+6x=-6\\\\\Longrightarrow 3y=-6-6x\\\\\Longrightarrow y=-\frac{6}{3} -\frac{6}{3}x \\\\\therefore \boxed{y=-2x-2}[/tex]

Thus, we can conclude the slope of line 1 is -2.

(2) - Answering part (a)

To find a line that is parallel to line 1, the slopes must be the same, -2. Use the point-slope form for a line to find the equation for line 2.

[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Point-Slope Form:}}\\y-y_1=m(x-x_1)\\\bullet \ m \ \text{is the slope of the line}\\\bullet \ (x_1,y_1) \ \text{is a point the line passes through}\end{array}\right}[/tex]

[tex]y-y_1=m(x-x_1); \ \text{Recall that} \ m=-2 \ \text{and} \ (x_1,y_1)=(9,0)\\\\\Longrightarrow y-0=-2(x-9)\\\\\therefore \boxed{\boxed{ y=-2x+18}}[/tex]

Thus, the equation for line 2 is found.

(2) - Answering part (b)

To find a line that is perpendicular to line 1, the slope of line 3 must be the opposite-reciprocal of line 1's. Once again, use the point-slope form of a line to find the equation of line 3.

[tex]y-y_1=m(x-x_1); \ \text{Recall that} \ m=\frac{1}{2} \ \text{and} \ (x_1,y_1)=(9,0)\\\\\Longrightarrow y-0=\frac{1}{2}(x-9)\\\\\therefore \boxed{\boxed{ y=\frac{1}{2} x-\frac{9}{2} }}[/tex]

Thus, the equation of line 3 is found.

Using the proportion principle , Orange Juice has a greater percentage of water than Apple juice

To determine which juice has a greater percent of water, we need to calculate the percentage of water in each juice.

Percentage of water = (Water content / Total content) * 100

Water content = 32 ounces

Total content = 80 ounces

Percentage of water in apple juice = (32 / 80) * 100 = 40%

Water content = 48 ounces

Total content = 64 ounces

Percentage of water in orange juice = (48 / 64) * 100 = 75%

Comparing the percentages, we can conclude that orange juice has a greater percentage of water (75%) than the apple juice (40%).

To determine which box can hold all the cubes, we need to calculate the volume of each box and compare it to the volume occupied by the cubes.

The volume of a rectangular box is calculated by multiplying its length, width, and height.

Box A:

Volume = 4" x 6" x 8" = 192 cubic inches

Box B:

Volume = 6" x 3" x 12" = 216 cubic inches

Box C:

Volume = 6" x 6" x 4" = 144 cubic inches

Since the cubes have a side length of 1 inch, the volume occupied by 200 cubes would be:

Volume of cubes = 200 cubic inches

Comparing the volumes, we find that:

- Box A has a volume of 192 cubic inches, which is less than the volume of the cubes.

- Box B has a volume of 216 cubic inches, which is greater than the volume of the cubes.

- Box C has a volume of 144 cubic inches, which is less than the volume of the cubes.

Therefore, the box that would be able to hold all 200 cubes is Box B: 6" x 3" x 12".

Therefore, the expression becomes:

7/1 - 2/6

Now, we need to find a common denominator for the fractions, which is 6:

7/1 - 2/6 = (76)/(16) - 2/6

= 42/6 - 2/6

= (42 - 2)/6

= 40/6

Finally, we can simplify the fraction:

40/6 = 20/3

So, the difference between 5 2/6 and -2 4/6 is 20/3.

Step-by-step explanation:

First, let's subtract the whole numbers: 5 - (-2) = 5 + 2 = 7.

Next, let's subtract the fractions: 2/6 - 4/6 = (2 - 4)/6 = -2/6.

Combining the whole number and fraction results, we have:

7 - 2/6

Now, to simplify this result further, we can express 7 as a fraction with a common denominator of 6:

The monthly payment on the 15-year fixed rate mortgage is $515.27.

The bank requires a 10% down payment on the condo price of $80,000.

Down Payment = 10% of $80,000

Down Payment = 0.1 * $80,000

Down Payment = $8,000

Therefore, the required down payment is $8,000.

Amount of the Mortgage:

To find the amount of the mortgage, we subtract the down payment from the condo price.

Amount of Mortgage = Condo Price - Down Payment

Amount of Mortgage = $80,000 - $8,000

Amount of Mortgage = $72,000

Therefore, the amount of the mortgage is $72,000.

Now, Monthly Payment = (Loan Amount x Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate) ^ (-Number of Months))

Monthly Interest Rate = Annual Interest Rate / 12

= 3.5% / 12 = 0.035 / 12

= 0.002917

and, Number of Months = 15 years x 12 months = 180 months

So, Monthly Payment = ($72,000 x 0.002917) / (1 - (1 + 0.002917) ^ (-180))

Monthly Payment ≈ $515.27

The volume of a cube is given by V = s³, where s is the side length.

Therefore, the volume of each package is (1/4)³ = 1/64 cubic feet.

The volume of the part of the truck being filled:

The dimensions of the rectangular prism-shaped part of the truck are:

Length = 8 feet

Width = 6(1/4) feet = 6.25 feet

The volume of a rectangular prism is given by V = length × width × height.

Therefore, the volume of the part of the truck being filled is:

8 × 6.25 × 7.5

= 375 cubic feet.

To calculate the greater number of packages that can fit in the truck, we divide the volume of the part of the truck by the volume of each package:

Step-by-step explanation:

You want the area of the composite figure that is an 8-inch square with a semicircle removed.

The missing semicircle has a diameter of 8 in, so a radius of 4 in. The area of that half-circle is ...

  A = 1/2πr² = (π/2)(4 in)² = 8π in² ≈ 25.1 in²

The area of the square without the semicircle removed is ...

  A = s² = (8 in)² = 64 in²

After removing the semicircle from the square, the remaining area is ...

  A = square area - semicircle area

  A = 64 in² -25.1 in² = 38.9 in²

To solve this problem, we need to find the circumference of the circular playground and then multiply it by the number of rounds the runner completes.

The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * radius

Given that the radius of the playground is 77m, we can substitute this value into the formula to find the circumference:

Circumference = 2 * π * 77

Now, we need to calculate the distance covered by the runner in 5 complete rounds. Since one round is equal to the circumference, the distance covered in 5 rounds would be:

Distance = 5 * Circumference

Substituting the value of the circumference, we have:

Distance = 5 * (2 * π * 77)

To simplify, we can use an approximation of π as 3.14:

Distance ≈ 5 * (2 * 3.14 * 77)

Calculating further:

Distance ≈ 5 * (6.28 * 77)

Distance ≈ 5 * 483.56

Distance ≈ 2417.8

Therefore, the distance covered by the runner in 5 complete rounds around the circular playground is approximately 2417.8 meters, which can be rounded to 2420 meters (as given in the answer).

The value of x is approximately 34.02.

Given that in a rectangle with length 31 and width is 14 and the diagonal length is x.

To find the value of x using the Pythagorean Theorem, we can consider the rectangle as a right triangle, where the length and width of the rectangle form the two sides of the triangle, and the diagonal length (x) is the hypotenuse.

According to the Pythagorean Theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Applying the given data gives,

[tex]x^2 = length^2 + width^2[/tex]

Substituting the given values into the equation:

diagonal length [tex]x^2 = 31^2 + 14^2[/tex]

diagonal length [tex]x^2[/tex] = 961 + 196

diagonal length [tex]x^2[/tex] = 1157

To find x, we take the square root of both sides:

Answer:

32 inches Aprox

Step-by-step explanation:

To find the size of a rectangular television screen given its height and width, we can use the Pythagorean theorem. The diagonal measurement (size) is the hypotenuse of a right triangle formed by the height and width.

Given:

Height of the television screen (h) = 20 inches

Width of the television screen (w) = 25 inches

Using the Pythagorean theorem:

diagonal² = height² + width²

diagonal² = 20² + 25²

diagonal² = 400 + 625

diagonal² = 1025

Taking the square root of both sides:

diagonal ≈ √1025

diagonal ≈ 32.02

Rounding to the nearest inch, the size of the television screen is approximately 32 inches.

Therefore, the size of the rectangular television screen, rounded to the nearest inch, is 32 inches.
