187=190
186=190 because 18.7 and 18.6 are 187 and 186 so 8 is the tenth place. So they both equal 190
Step-by-step explanation:
C= pi×d
d=.5 meters
so plug in the numbers
3.14 × .5= 1.75
circumference= 1.75 meters
Answer:
An equation is 
Step-by-step explanation:
Let
be the measure of the unknown acute angle.
According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.
One of the acute angles of a right triangle is equal to 52°.
Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.

So, an equation is 
Answer:no
Step-by-step explanation:put the two numbers in the same denominator
The least common denominator of 8 and 12 is 24. So to get 8 to 24 you multiply it by 3. So 3(3/8) is 9/24.
To get 12 to 24 you multiply it by 2. So 2(7/12) is 14/24. 9/24 is less than 14/24.
Answer:
(b^2 + 8b - 9) - (11b^2 + 4b -7)
b^2 + 8b - 9 - 11b^2 - 4b + 7
- 10b^2 + 12b -16
Step-by-step explanation:
