Answer:
0.01485...
Step-by-step explanation:
<u>Given:</u>
- A seal has 1,500 nerves per whisker
- This is 101,010 times as much as a rat has per whisker
<u>We will:</u>
- Divide the number 1,500 by 101,010
1,500 ÷ 101,010 = 0.0148500149
0.0148500149 ⇒ 0.01485 when rounded
Your answer: 0.0148500149, 0.01485 when rounded

Answer:
2:15 pm
Step-by-step explanation:
The time that Theo finishes is the sum of the start time and the duration of the cleaning. The duration is the sum of the cleaning times for each of the rooms and the break time.
__
<h3>sum of minutes</h3>
It is convenient to convert all of the times to minutes, then convert the total back to hours and minutes.
kitchen +lounge +bedroom +bathroom +breaks
= (60 +50) +(55) +(1/2×60) +(35) +(85)
= 110 +55 +30 +35 +85
= 315 . . . . minutes
<h3>minutes and hours</h3>
There are 60 minutes in an hour, so the sum is ...
(315/60) hours = 5 15/60 hours = 5:15 . . . . written as hours : minutes
Then the time Theo finishes is ...
9:00 +5:15 = 14:15 = 2:15 pm
Theo will finish cleaning at 2:15 pm.

<em>Additional comment</em>
On a 24-hour clock, hours after noon are numbered 13, 14, 15, ... to 23 at 11 pm. The 12-hour representation of the pm hours can be found by subtracting 12 from the hour number.
Answer:
A)58cm
B)
C)125.55square cm
Step-by-step explanation:
AB is a line is symmetry
Total length of left half part=12cm+9cm+3cm+5cm
Total length of left half part=29 cm
Length of left half part=Length of right half part
Therefore, length of right half part=29 cm
A) Perimeter of the shape=29cm+29cm=58cm
B)
Pythagoras theorem
Hypotenuse=12 cm
Base=5+3=8cm
In triangle ADC
Now, using Pythagoras theorem
C)
Area of shape=Area of triangle+ area of rectangle
Area of shape=
Where l=9cm
breadth=3+3=6cm
h=
base=2(5)+3(2)=16cm
Area of shape=
Area of shape=125.55 square cm
Answer:
? = 3
Step-by-step explanation:
given a line parallel to a side of the triangle and intersecting the other 2 sides, then it divides those sides proportionally , that is
= 
( cross- multiply )
4? = 12 ( divide both sides by 4 )
? = 3
