Answer:

(For page 1) volume=Length x width x height

so area is Length x width, therefore you would just take 2,025 and divide by 9 to get 225 sq. ft for the area. (For page 2) the volume of the aquarium is V= Lx wx H

it is already given that V=11.25 cubic feet, so 11.25=LxWxH

H height and it is the aquarium's depth

H=11.25 / L xW= 11.25/2.5x1.5= 3 feet

Answer:

17.6

Step-by-step explanation:

I like to approach surface area problems by solving the invdividual 2d shapes on the figure.

First we will solve the triangle(s)

1/2xbh=a

1/2x2=a

1=a

As there is another triangle reflected behind it we so far have 2 units.

Now we solve the 3 rectangles in the figure

3x2.2 = 6.6 (first slanted rectangle)
3x1= 3 (bottom rectangle)

2x3=6 (side rectangle)

Now we add up all our units

2 + 6 + 3 + 6.6

17.6 = SA

Answer:

x = 30°

The angles:

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

We can replace 30° for all the angles.

The measures are:

2x = 60

3x = 90

x = 30

All triangles have 3 angles that add up to 180 degrees. We can use the information to create an equation.

Finding x

First, add all of the angles together and set them equal to 180

Next, combine like terms

Finally, divide both sides by 6

Solve For Missing Angles

Now that we have x, we can solve from each of the missing angles. Do this by plugging in 30 for the x-values.

2x

3x

x

We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.

Answer:

Plane B is closer.

Step-by-step explanation:

Plane B is closer.

The distance for Plane A is 7.9 km.

The distance for Plane B is 7.4 km.

Step-by-step explanation:

To find the distance to the tower, altitude must be converted to kilometers. Each 1000 ft is 0.3048 km, so the heights of the planes are ...

-- Plane A: (20 thousand ft)*(0.3048 km/thousand ft) = 6.096 km

-- Plane B: (8 thousand ft)*(0.3048 km/thousand ft) = 2.4384 km

The Pythagorean theorem can be used to find the distance from each plane to the tower:

-- distance = √((ground distance)² + (height)²)

-- Plane A distance = √(5² +6.096²) ≈ √62.16 ≈ 7.9 . . . km

-- Plane B distance = √(7² +2.4384²) ≈ √54.95 ≈ 7.4 . . . km

The distance for Plane B is shorter, so Plane B is closer to the tower.

Answer:

5(x-3)(x-3)

Step-by-step explanation:

First we can divide everything by 5:

[tex]\frac{5x^{2} -30x+45}{5} = x^{2} -6x+9[/tex]

Now we find 2 numbers that multiply to give +9 and add to give -6:

This would be -3 and -3. Now we substitute these numbers inside of -6 by splitting -6x into -3x and -3x:

[tex]x^{2} -3x-3x+9[/tex]

Now we factor the first 2 terms:

[tex]x(x-3)[/tex]

Now we factor the last 2 terms:

[tex]-3(x-3)[/tex]

Now we only copy one bracket and the things outside the bracket we put them into 1:

(x-3)(x-3)

Now we multiply everything by 5 :

5(x-3)(x-3)

Answer:

5(x-3)( x-3)

Step-by-step explanation:

First we notice that all the factors are divisible by 5 because the ending of the coefficients is 0 or 5

5 (x² -6x+9)

5 ( x -3) ² , because x² -6x+9 = 9x-3)²

5 (x-3)( x-3)

Answer:

D. the absolute deviation is 3

Step-by-step explanation:

Given:

MAD:

[tex]\displaystyle \large{\dfrac{1}{n}\sum_{i=1}^{n}|x_i-m| = \dfrac{|x_1-m|+|x_2-m|+|x_3-m|+...+|x_n-m|}{n}}[/tex]

Therefore:

[tex]\displaystyle \large{MAD=\dfrac{|7-12|+|10-12|+|10-12|+|14-12|+|14-12|+|17-12|}{6}}\\\displaystyle \large{MAD=\dfrac{5+2+2+2+2+5}{6}}\\\displaystyle \large{MAD=\dfrac{18}{6}}\\\displaystyle \large{MAD = 3}[/tex]

Therefore, absolute deviation is 3

Step-by-step explanation:

2x° + 2x° + 76° = 180° ( being supplementary angle )

4x° = 180° - 76°

4x° = 104°

x = 104/4

x = 26°

Answer:

1. 30.5

2. 23

Step-by-step explanation:

1. Find the middle of 30 and 31.

2. 21, 22, 23, 24, 25...now cross of a number from each side at a time until you get to the middle.

You put the numbers from smallest to biggest and cross off one number at a time from each side until you get to the middle.

If at the end you have two numbers left, you find the middle for these two numbers.

Answer:

1) 30.5

2) 23

3) 50

4) 2

5) 100

Step-by-step explanation:

First of all, order your data from lowest to highest value. Next, if you have an even number of observations (like in question n. 1 and n. 3) you have to add the middle two observations and divide the result by two. If you have an uneven number of observations, your median is simply going to be the number in the middle. Here, I'll show you:

- Question 1 has 2 observations, meaning you have to compute 30+31 = 61. Now you divide 61 by 2:

61/2 = 30.5 and that's your median.

- In question 2 you firstly have to order the data from lowest to highest number. Since it's an uneven number, your median is going to be 23.

- Question 3 has 4 observations, meaning you have to firstly order in ascending order and find the middle 2 numbers, which are 30 and 70. You add them: 30 + 70 = 100.

100/2 = 50 and that's your median.

- In question 4, after you order in ascending order you can clearly see that your median is 2.

- In question 5, after you order in ascending order you can clearly see that your median is 100.

Answer:

120 degree, corresponding angles

Step-by-step explanation:

Angle l is 120 degree. You could measure using a protractor.

The relation between angle H and angle L is that they are corresponding angles.

Reason: a and b are parallel line.

Answer:

1928

Step-by-step explanation:

1927.83505155 rounded to the nearest whole number is 1928. A whole number is a number with no decimal places, so we'll have to look at the number directly to 7's right (the first decimal) in order to find out whether we'll be rounding up or down. This number is 8, which is closer to 10 than it is to 0, so we'll be rounding up.

1927 + 1 = 1928, and this is our final answer. Hopefully this was helpful! Let me know if you have any further questions on the subject.

Complete the square:

F(x) = -3x² - 6x - 5

F(x) = -3 (x² + 2x) - 5

F(x) = -3 (x² + 2x + 1 - 1) - 5

F(x) = -3 ((x + 1)² - 1) - 5

F(x) = -3 (x + 1)² + 3 - 5

F(x) = -3 (x + 1)² - 2

The y-intercept has x-coordinate equal to 0, so it corresponds to the value of F(0) :

F(0) = -3 (0 + 1)² - 2 = -3 - 2 = -5

The axis of symmetry is the vertical line running through the vertex of this parabola, so we'll come back to this.

The vertex of the parabola is (-1, -2). This represents the maximum value of F(x), which follows from

(x + 1)² ≥ 0   ⇒   -3 (x + 1)² ≤ 0   ⇒   -3 (x + 1)² - 2 ≤ -2

This is to say, every point on the parabola has a y-coordinate no greater than -2.

As mentioned earlier, the axis of symmetry is the vertical line through the vertex, and its equation is determined by the x-coordinate of the vertex. Hence the AoS is the line x = -1.
