a rectangular window has diagonal window panes, as shown in the picture below. what is the length of each diagonal?
vova2212 [387]

Answer:

D. 4 ft.

Step-by-step explanation:

Diagonals are the lines that extend from one corner of the square/rectangle to the opposing/reflectory side. So an example of a diagonal would be from the upper left hand corner of this shape to the lower right hand corner. This would be a diagonal. Since We know that both diagonals intersect at the center, each diagonal halves itself. So, since we know that 1/2 of a diagonal = 2 feet, then if we add the second half of the diagonal, or 2 more feet, we get the length of a diagonal.

2 ft. + 2 ft. = 4 ft.

And since the lengths of diagonals in squares and rectangles are congruent, we can see that if one diagonal is equal to 4 ft., then the length of the other diagonal will also be 4 ft.

An oblique cylinder with a base of radius 2 units is shown. The top
Anuta_ua [19.1K]

The volume of the cylinder is the amount of space on it

The volume of the oblique cylinder is 174.19 cubic units

<h3>How to determine the volume of the cylinder?</h3>

The given parameters are:

AB = 16 units

Radius (r) = 2 units

\theta = 30^o

Start  by calculating the height (h) using:

h = 16 * \cos(30^o)

This gives

h = 13.86

The volume of the cylinder is then calculated as:

V = \pi r^2 h

This gives

V = 3.142 * 2^2 * 13.86

V = 174.19248

Approximate

V = 174.19

Hence, the volume of the oblique cylinder is 174.19 cubic units

If a=3, b=-5 fond the value of (2a+3b) (4a sq- 6ab+9b square)​
snow_lady [41]

Step-by-step explanation:

(2a+3b)(4a²-6ab+9b²

(2a+3b){(2a)²-2a×3b+(3b)²}

Because (a³+b³)=(a+b)(a²-ab+b²)

Therefore,

(2a+3b){(2a)²-2a×3b+(3b)²}

=(2a)³+(3b)³

By substituting the values , we get

  • (2a)³+(3b)³
  • (2×3)³+(3×(-5))³
  • 6³+(-15)³
  • 216+(-3375)
  • 216-3375
  • -3159

In a game the player wins if he rolls a 6 on a number cube. If the number cube is rolled 18 times, then what is a reasonable pre
monitta

Answer:

15/18

Step-by-step explanation:

A single di has 6 sides, meaning the probability of rolling a 6 is 1/6. So if you roll a di 18 times you would probably get 6 three times. Meaning the number of unsuccesful rolls would be (18/18 - 3/18). Hope this helps.
