Answer:
<h3>Both are correct</h3>
Step-by-step explanation:
All the sides of an equilateral triangle are equal. Hence;
Perimeter of an equilateral triangle = 3S
S is one of the side length
Given;
S = 4n-2
Perimeter of the triangle = 3(4n-2)
This can also be expressed as P = S + S + S
P = (4n-2) + (4n-2) + (4n-2)
This shows that both methods are correct
Answer:
10
Step-by-step explanation:
The sum of exterior angles for any polygon is 360.
so first add up all the given exterior angle:
30+35 = 65.
next, find all the exterior angles that you can find:
Exterior angle = 180-interior angle
so:
180-90 = 90
180-135 = 45
180-120 = 60
180-90=90
These are all that we can find.
now add these to 65:
90+45+60+90+65 = 350
To find x, subtract 350 from 360, which is the sum of exterior angles.
360-350 = 10
Hope this helps
Good Luck
Hi there! So Andy's total lunch bill was $20 and the drink was 15% of the bill. Percents are parts of 100 and 100 - 15 is 85. That means 85% of the total bill was Andy's food cost. Let's multiply 20 by 85% ti get the cost of his food. 20 * 85% (0.85) is 17. Andy's food costed $17. Here are the answers broken down to be easier to read.
Percent of Andy's bill with food: 85%
Cost of food: $17

Answer:
10.55%
Step-by-step explanation:
Given:
Initial weight of the new born baby = 3,874 grams
final weight of the baby = 3,465 grams
Now,
the current percentage of the weight loss will be calculated as:
Weight loss percentage = 
%
on substituting the respective values, we get
Weight loss percentage = 
%
or
Weight loss percentage = 10.55%
