What is cannonballs?

A cannon constitutes a large-caliber gun that belongs to the artillery category. It typically fires a projectile propelled by an explosive chemical. Prior to the development of smokeless powder in the late 19th century, gunpowder (sometimes known as "black powder") served as the main propellant.

Depending on their intended purpose on the battlefield, different types of gun combine and balance these characteristics to differing degrees. Cannons differ in gauge, effective range, mobility, rate of fire, angle of fire, and firepower. A large artillery weapon is a cannon.

By utilizing the formula of a square pyramid,

n(n+1)(2n+1)/6

12(12+1)(2(12)+1)/6

12(13)(25)/6

2*13*25

=650

Therefore, 650 is the number of cannonballs.

Mr. Dolezal says the first step is to evaluate 12. Explain Mr. Dolezal’s mistake. Then, evaluate the expression.

Answers

he didn’t follow PEMDAS which is the an acronym for the order of operations. according to pemdas the first step is parenthesis (which is the p in pemdas) there fore the first step is to add the 1 and the 2
then since there are no exponents you multiply so you multiple 5(3) which is 15
then you can add all the number left to right
so 15+2+3= 20
so the answer is 20
hope this helped

A car travels 70 miles in 80 minutes. Which is its average speed per minute?a. 11 miles
b. 8.75 miles
c. 1.14 miles
d. 0.875 miles User: gopd

Answers

Answer:

The average speed per minute of the car is :

d. 0.875(mi)/(min)

Step-by-step explanation:

The average speed tells you the speed of an object over time, it can be expressed as:

A_(s)=(Distance)/(Time)

As the car travels 70 miles in 80 minutes, we can replace values in the equation:

Distance = 70 miles

Time = 80 minutes

A_(s)=(Distance)/(Time)

A_(s)=(70miles)/(80minutes)

A_(s)=0.875(mi)/(min)
70/80 = miles per minute.
70/80 = 0.857 miles per minute

Answer: d. 0.875 miles
