Cone=cup:
V=124<span>cm^3.
h=12cm
V=Bh
P=r</span>^2π+rsπ:
B=r^2π
B=V/h=124/12=10,3cm^2
r^2=B/π
r=√(B/π)=1,81 cm
S=√(r^2+h^2)=√(12^2+1.81^2)=√(144+3,28)=12,13 cm
P=r^2π+rSπ=3,28*3,14+1,81*12,13*3,14=10,29+68,93=79,22 cm^2

Simple interest will be derived by multiplying the principal, the interest rate, and the term.
Interest = Principal x Rate x Term
Interest = 105
Principal = 700
Rate = 0.05
Term = ?
Based on the Simple Interest formula,
term = Interest / principal x rate
term = 105 / (700 x 0.05)
term = 105 / 35
term = 3
Answer:
60+2x≥300
Step-by-step explanation:
So we know that she makes a base of $60 a week and gets $2 extra for every item she sells. First, we set up an equation for how many items she would have to sell to make exactly $300 in a week. 60+2x=300. Now, all we do is replace the equal sign with a ≥ sign because it says at least which means more than or equal to.
Answer:
3
Step-by-step explanation:
Find n first.
n+10= 40
Subtract 10.
n= 30
Plug in n.
30-25= 5
The answer is 5.
I hope this helps!
