Answer: 21,984.44581% of change

Step-by-step explanation:

First you want to use the formula for cylinders which is V = pi r^2 h

V = 3.14 (15)^2 (120)

V = 3.14 (225) (120)

V = (706.5) (120)

V = 84,780 ft.

This volume (84,780) would be the volume of a whole tank, but since both the tanks are only half a cylinder, the volume of each holding tank would be half this number. Therefore, 84,780/2= 42390 ft which is the volume of each individual holding tank, but since we have 2 holding tanks we would multiply 42390 by 2 which is 84,780 ft (the volume of both the holding tanks together).

If all linear dimensions are 6 times smaller then that means we take 6 to the third power which is 216.

The mock up would be 3 times smaller.

To the nearest millimeter, a cell phone is 74 mm long and 42 mm wide. What is the ratio of the width to the length?

sergij07 [2.7K]

Answer:

You will want to compare the width to the length, or 42 mm/ 74mm ...the units cancel, which is what you want for a ratio...and you usually want to simplify your ratio

Hope that helps

If AC is parallel to DE, find X

UNO [17]

Answer: x = 50

Concept:

Here, we need to know the idea of alternative interior angles and the angle sum theorem.

Alternative interior angles are angles that are formed inside the two parallel lines, and the values are equal.

The angle sum theorem implies that the sum of interior angles of a triangle is 180°

If you are still confused, please refer to the attachment below or let me know.

Step-by-step explanation:

Given information:

AC ║ DE

∠ABC = 85°

∠A = 135°

Find the value of ∠BAC

∠A + ∠BAC = 180° (Supplementary angle)

(135°) + ∠BAC = 180°

∠BAC = 45°

Find the value of ∠BCA

∠ABC + ∠BAC + ∠BCA = 180° (Angle sum theorem)

(85°) + (45°) + ∠BCA = 180°

∠BCA = 50°

Find the value of x (∠EBC)

∠EBC ≅ ∠BCA (Alternative interior angles)

Since, ∠BCA = 50°

Therefore, ∠EBC = 50°

$\Large\boxed{x=50}$

Hope this helps!! :)

This figure is made up of a rectangle and parallelogram.

Oduvanchick [21]

Given the coordinates of two points, P1 and P2, the distance formula between these two points is deduced.
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
To find the area of the figure we must first find the area of the rectangle and add the area of the parallelogram.
rectangle area
A = (L) * (w)
L = root ((- 6-2) ^ 2 + (- 1-1) ^ 2) = 8.25
w = root ((- 6 - (- 5)) ^ 2 + (- 1 - (- 5)) ^ 2) = 4.12
A = (8.25) * (4.12) = 33.99
Parallelogram area
A = (b) * (h)
b = root ((3-3) ^ 2 + (3 - (- 3)) ^ 2) = 6
h = root ((3-2) ^ 2 + (3-3) ^ 2) = 1
A = (6) * (1) = 6
The total area is then
Atotal = 33.99 + 6 = 39.99 units ^ 2
Answer
the area of this figure is 39.99 units ^ 2
