Answer:
153.94
Step-by-step explanation:
c=2r*r
The radius is half of the diameter.
To find the radius you will divide 49 inches by 2.
You should get a total of 24.5
Now that you have your radius you are going to use the circumference formula to solve.
C= 2r*r
C=2(24.5)*(24.5)
type that into the calculator (without the parenthesis) and boom your done!
You answer should be 153.938
then you round to get a total of 153.94

Answer:
b²+3.5a+8.4b
Step-by-step explanation:
Given the expression
3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2
Expand
3b^2 + 2a+10.8b -2.4b + 1.5a - 2b^2
Collect the like terms
= 3b²-2b²+2a+1.5a+10.8b-2.4b
= b²+3.5a+8.4b
Hence the equivalent expression is b²+3.5a+8.4b
Answer:
Step-by-step explanation:
5x+10-7=-32
5x+3=-32
5x+3-3=-32-3
5x=-35
X=-35/5
X=-7
Check:
5(-7+2)-7=32
5(-5)-7=32
-25-7=-32
-32=-32
This is correct

Answer: the top of the ladder is at 24 feet from the ground
Step-by-step explanation:
Use the Pythagorean theorem to solve for the unknown, since we notice that the ladder is the hypotenuse of a right angle triangle formed by the horizontal distance from the wall to the base of the ladder, and the height of the top of the ladder against the wall. We need to find one of the triangle's sides given its hypotenuse and the other side, so we use the formula:
