Hi, it is very simples.
Look :
2a - 9 = -85
Pass the term -9 to the left side of equation, but changing the sinal
2a = -85 + 9
Sum -85 +9 = -76
Then,
2a = -76
Nos, pass the 2 dividing -76
a = -76 ÷ 2
a = - 38
This is the answer to the yours question

Step-by-step explanation:
One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
I’m pretty sure you’re right. hope this helps:)
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The <span>spherical bubble gum ball is at the bottom
- The radius of the cone is 1.5 inches, and its height is 3 inches.
- The diameter of the bubble gum ball is 0.5 inches.
2. Therefore, you must apply the formula for calculate the volume of a sphere to find the volume of the bubble gum ball:
Vs=4</span>πr^3/3
r is the radius (r=0.5 inches/2=0.25 inches)
Vs=4π(0.25 inches)^3/3
Vs=0.065 inches^3
3. The volume of the cone is:
Vc=πr^2h/3
r is the radius of the cone (r=1.5 inches)
h is the height (h= 3 inches)
Vc=π(1.5 inches)^2(3 inches)/3
Vc=7.06 inches^3
W<span>hat is the closest approximation of the volume of the cone that can be filled with flavored ice?
Vt=Vc-Vs
Vt</span>≈7.00 inches^3
