Answer:

14 units

Step-by-step explanation:

Notice that the x-coordinates of the two given points are the same:  -3.  Thus, the distance from one of these points to the other is a vertical one only, as x does not change.

The vertical distance is 9 - (-5), or 14 units.

URGENT Match each ratio of the volumes of two solids to the pair of solids it represents.
Anarel [89]
1. cylinder to cone:
  (πr^2h)/((1/3)πr^2h) = 3:1

2. sphere to cylinder:
  ((4/3)πr^3)/(πr^2h) = 4r:3h

3. cone to sphere:
  ((1/3)πr^2h)/((4/3)πr^3) = h:4r

4. hemisphere to cylinder:
  half the ratio of sphere to cylinder = 2r:3h

1.3 lesson help please
Airida [17]

Answer:

1. 125

2. 25

3. 40

4. 39

First question:

(15-10)^2 + (15-5)^2

parentheses first to get 5^2 + (15-5)^2

exponents next to get 25 + (15-5)^2

parentheses again 25 + 10^2

exponents again 25 + 100 = 125

Second question:

simplify the exponents (3 *3) + (4 * 4) + (2 * 2) to get 9 + 16 + 4 = 29

Third question:

simplify in the parentheses 6 1/7 - 1/7 = 6

divide 60 by 6 to get 10

multiply 10 by 4 to get 40!

Fourth question:

simplify the fractions to get 1/3 + 8/3 = 3

multiply the 3 by 13 to get 39

The triangles that are similar would be ΔGCB and ΔPEB  due to Angle, Angle, Angle similarity theorem.

<h3>How to identify similar triangles?</h3>

From the image attached, we see that we are given the Parallelogram GRPC. Thus;

A.  The triangles that are similar would be ΔGCB and ΔPEB  due to Angle, Angle, Angle similarity theorem.

B. The proof of the fact that ΔGCB and ΔPEB are similar pairs of triangles is as follow;

∠CGB ≅ ∠PEB  (Alternate Interior Angles)

∠BPE ≅ ∠BCG  (Alternate Interior Angles)

∠GBC ≅ ∠EBP  (Vertical Angles)

C.  To find the distance from B to E and from P to E, we will first find PE and then BE by proportion;

225/325 = PE/375  

PE = 260 ft

BE/425 = 225/325  

BE = 294 ft

Add or Subtract to Simplify:<br> (4x - 2x3) + (5x3 - 4x + 5)
sukhopar [10]

Answer:

<h2>3x³ + 5</h2>

Step-by-step explanation:

( 4x - 2x³ ) + ( 5x³ - 4x + 5)

<u>Remove the parenthesis</u>

That's

4x - 2x³ + 5x³ - 4x + 5

<u>Group like terms</u>

We have

5x³ - 2x³ + 4x - 4x + 5

We have the final answer as

<h3>3x³ + 5</h3>

Hope this helps you
