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

Step-by-step explanation:
Answer:
1st place on perimeter is 40
last on perimeter is 100
2nd place on # of bricks is 150
Step-by-step explanation:

A rectangle has a length of 6 inches and a width of 8 inches. A square with a side length of 3 was cut out of it. What is the area of the remaining paper
Answers
Answer: 39 inch²
Step-by-step explanation:
The rectangle's area was:
= Length * Width
= 6 * 8
= 48 inches²
The square's area is:
= Length * width
= 3 * 3
= 9 inches²
The square was cut out of the rectangle which means the area of the square should be deducted from the rectangle to find out the remaining area.
= 48 - 9
= 39 inch²
What is the Value of X in the triange
Answers
Answer:
x = 65
Step-by-step explanation:
The sum of the angles of a triangle add to 180
25+ 2x+25 = 180
Combine like terms
50+2x = 180
Subtract 50 from each side
2x = 180-50
2x =130
Divide by 2
2x/2 =130/2
x =65
Solve by factoring X^2-100=0

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
5 x 7 .= 35
315/35 = 9

Answer:
4. 1.3 cm³
5. 621.2 mm³
6. 116.5 m³
Step-by-step explanation:
The height to the peak of the pyramid is one side of the right triangle that has its hypotenuse equal to the slant height, and one leg equal to half the base side length. The Pythagorean theorem is used to find the height from the slant height (s) and the base length (b):
h = √(s² -(b/2)²)
The volume is found from the formula ...
V = (1/3)b²h
where b is the base length and h is the height found using the previous formula.

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
