Answer: Meaghan is right.
Step-by-step explanation:
For a number like:
123.45
the tens place would be the "2" (second number at the left of the decimal point)
The ones place would be the "3" (first number at the left of the decimal point)
Let's suppose that Lily is correct.
Then the quotient of:
43.61/7
Will be a number with two digits in the left of the decimal point.
The smallest number that meets this condition, is the number 10.
Then let's see:
7*10 = 70
then:
70/7 = 10
and:
43.61 < 70
(70 is larger than 43.61)
then:
43.61/7 < 70/7 = 10
Then:
(43.61/7) < 10
This means that our quotient is smaller than 10, then the first digit of the quotient can not be on the tens place.
Then Meaghan is the correct one.
We also could perform the quotient to find:
43.61/7 = 6.23
So yes, Meaghan is correct.
Radiation from the sun heats the Earth's surface by means of rays that are trapped in the atmosphere and allow the Earth to have constant heat.
<h3>How is the Earth's surface heated?</h3>
The surface of the Earth heats up due to the sun's rays that hit it and when they enter the atmosphere they are reflected on the surface being trapped between the atmosphere and the surface.
Another important aspect to keep in mind is that the rays strike at different angles throughout the Earth, for example:
- In the equatorial zone they affect directly, so this zone tends to be more quality than others in which the rotation and translation of the Earth cause the rays to enter in less or more quantity throughout the year.

Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Side links are : 3m, 4m, 5m
The perimeter of a triangle = (a + b + c)
Perimeter 1= (3 + 4 + 5) = 12m
If the side links are multiplied by 4 :
3*4 = 12 m
4*4 = 16m
5*4 = 20m
Perimeter2 = (12 + 16 + 20) = 48 m
Comparing the perimeters:
Perimeter 1 = perimeter 2
12 = 48
Hence, perimeter also increases by 4 folds
Answer:
if angle 2 is 117 degrees, angle 3 is supplemental and would be 63 degrees.
180-117=63
