Answer:

4

Step-by-step explanation:

First, you have to right out the equation, which is

3n + 18 = 30

To solve the equation, subtract 18 from both sides,

3n = 12

Then, divide both sides by 3

n = 4

Hope this helps!!

Volume of a cone formula: V = πr²*h/3

V = volume

r = radius

h = height

Solve with the given values.

V = π(7)²*19/3

V = π(49)*19/3

V = 153.86*19/3

V = 974.94...

Round to the nearest one.

974.94... → 975.0

Therefore, the answer is 975.0yd³

Best of Luck!

Three pounds of lawn seed covers 1800 square feet how many 4 pound bags are needed to cover 8400 square feet.
VikaD [51]
You need to find the unit rate of 3 : 1800 first by dividing 1800 and 3

1800 ÷ 3 = 600

So this means for every 1 pound bag it covers 600 square feet. You now need to multiply 600 and 4 to see how many square feet 4 pounds cover.

600 × 4 = 2400

So each 4 pounds covers 2400 sq ft. Now you have to divide 8400 and 2400 to find how many bags of 4 pounds you need

8400 ÷ 2400= 3.5

You need 3.5 bags of 4 pounds.
Technically you would need 4 bags because you’d have to round it up.

Hope this helps you!! :)

The experimental probability that Pedro will hit a hole in one at the golf course is 2/5. If Pedro goes golfing 40 times in a ye
Sati [7]
I'm pretty sure you would need to multiply 2/5 by 40.

So, if you multiply 2/5 by 40, you need to turn 40 into a fraction with 1 being the denominator.

2/5 x 40/1 = 80/5

Since the product is an improper fraction, you would simplify it to a whole number.

80/5 = 16. 

He can expect to hit it 16 times to get a hole in one.

I hope I am right and have a great day.
