166+88+99+100=453
one hundred=100 that is why i put the 100
Add all together and you get 453.
Answer:
Area of shaded region = 351.68 cm²
Step-by-step explanation:
Area of a circle = πr²
where r = radius = 3.14
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94cm²
Area of smaller circle = 3.14 * 3²
= 3.14 × 3 × 3
= 28.26cm²
Area of shaded region = Area of bigger circle - Area of smaller circle
= (379.94 - 28.26) cm²
= 351.68 cm²
Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.
3)

The definition of supplementary angles is that two angles are supplementary if their measures sum to
180
∘
.
4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.
5)

Subtracting

from each side of 4. gives us the above result.
6) Definition of right angle
Step-by-step explanation:
Jake puts 6 stamps in his book every day.
30/6= 5
Jake put stamps in the book for 5 days.
So, Dan puts 5 stamps in the book every day.
5*5= 25
Dan has 25 stamps when Jake has 30.
I hope this helps!
