(2x+23)+(9x-5)=95
11x+18=95
x= 95-18/11
x=7
therefore substituting value of x in the given equations of angles:
angle ABD = 2(7)+23=37°
angle DBC = 9(7)-5= 58° Answer
to verify = 37°+58°= 95° ( which was given)
I believe the answer is the first option
1/2 first day
last day is 1 and 1/4
1/2=2/4
1 and 1/4=5/4
2/4+how many 1/4=5/4
answer is 3 of them
add 1 moe for the firs tday
3+1=4
4 days
Step-by-step explanation:
The formula for the area of a circle is π times the radius of the circle squared.
For 9, the diameter is 22. The radius is half the diameter, so it is 22/2=11.
The area of the circle is π*11^2=121π mm^2.
For 10, we already know the radius is 2.5.
The area of the circle is π*2.5^2=6.25π ft^2.
