Answer:
The number of sides are 360
Step-by-step explanation:
We are given
exterior angle is 1 degree
Firstly, we will find interior angle
interior angle = 180 - exterior angle
we can plug value
interior angle = 180 - 1
interior angle = 179
now, we can use formula
now, we can plug angle
now, we can solve for n
So,
The number of sides are 360
This is a simple formula:(a-b)*(a+b)= a^2-b^2
And it goes like this for your example: (a-1)*(a+1)=a*a+a-a-1*1=a^2-1^2=a^2-1
To get from 3 to 4 it’s 4/3
so 5.2 x 4/3 = 6.9 (1 d.p.)
6.9 - 5.2 = 1.7
X= 1.7
sorry If this is wrong :/
Answer:
4xy
Step-by-step explanation:
20x^2 y = 4*5 x^2 y = 2*2*5*x*x*y
16*x*y^2 = 4*4*x*y^2 = 2*2*2*2*x*y*y
what is common in both
2*2*x*y
4xy
Answer:
Step-by-step explanation:
Let the number of the problems the team could solve before is x.
<u>Then we have:</u>
- x + 40% = 42
- 1.4x = 42
- x = 42/1.4
- x = 30
They were able to solve 30 problems before the new mathletes joined
