You probably haven't learnt this but the general equations for circle with centre at the origin is x^2+y^2=R^2 where R is the radius of the circle so R^2=(1737+185)^2.I am lazy to press my calculator so type it in yourself.
Answer:
d=−bc+a/0.5bc
Step-by-step explanation:
Let's solve for d.
a=0.5bcd+bc
Step 1: Flip the equation.
0.5bcd+bc=a
Step 2: Add -bc to both sides.
0.5bcd+bc+−bc=a+−bc
0.5bcd=−bc+a
Step 3: Divide both sides by 0.5bc.
0.5bcd/0.5bc = −bc+a/0.5bc
d=−bc+a/0.5bc
Answer:
It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.
Step-by-step explanation:
4800 ÷ 20 = 240 sq ft per team member in 36 minutes
240 ÷ 36 = 6.67 sq ft per team member in 1 minute
6.67 × 9 = 60 sq ft per 9 team members in 1 minute
4200 ÷ 60 = 70 minutes (or 1 hour and 10 minutes)
Ends up=( K+5)1/2 -2
ends up=K/2+2.5-2=K(.5) + .5
