1. It is doubled

I can't help with paragraph explanation as it is something that you should write

2. The change in the area is that is 16 times more

No explanation as it is something that you should write

3. The change in area is that it is 9 times less

I can't help with paragraph explanation as it is something that you should write

Step-by-step explanation:

20 + 16 = 36

40 + 32 = 72

72/36 = 2

Hence it is doubled

(5 x 6) / 2 = 15

(20 x 24) / 2 = 240

240/15 = 16

It is 16 times more

15 x 21 = 315

Sloths climb through the canopy while hanging upside down. If it takes a sloth 10 minutes to climb 7.5 feet, what's its climbing speed in miles per hour?

Answers

Answer:

0.00852 miles per hour

Step-by-step explanation:

Given that:

Distance = 7.5 feets

Time taken = 10 minutes

Speed = distance / time taken

Speed = 7. 5 feets / 10 minutes = 0.75 feets / minutes

Converting to miles per hour :

0.75 feets / minute :

1 mile = 5280 feets

1 minute = 1/60 = 0.0166666 hour

0.75 feets / minute = (0.75/5280)mile / 0.0166666

= 0.0001420 / 0.0166666 mile per hour

= 0.0085200 miles per hour

= 0.00852 miles per hour

Answers

Answer:

31 units

Step-by-step explanation:

Given

[tex]AD = 3x + 7[/tex]

[tex]BC = 5x - 9[/tex]

Required

Find

If AD parallel to BC, then:

[tex]AD = BC[/tex]

This gives:

[tex]3x + 7 = 5x - 9[/tex]

Collect like terms

[tex]3x- 5x = -7-9[/tex]

[tex]-2x = -16[/tex]

Solve for x

[tex]x = 8[/tex]

A broken pottery shard found at an archaeological dig has a curved edge. Find the diameter of the
original plate. (Use the fact that the diameter PR is the perpendicular bisector of chord AB.) If necessary,
enter your answer as a simplified proper fraction or mixed number.

Answers

Answer: 18 1/2 inches

Step-by-step explanation:

Applying the segments of chords theorem, the diameter of the original plate is: PR = 18 ⅛ inches.

What is the Segments of Chords Theorem?

Based on the segments of chords theorem, the following equation is true:

(AQ)(QB) = (PQ)(QR)

Plug in the values

(9)(9) = (8)(QR)

QR = 81/8

QR = 10 ⅛ inches.

Diameter PR = QR + PQ

Diameter PR = 10 ⅛ + 8

Diameter PR = 18 ⅛
