Answer:

1. 4.7

2. 5,082

Step-by-step explanation:

1. To find the volume of a cone you use this formula V=\pi r^{2} \frac{h}{3}. The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve V=\pi (1.5)^{2} \frac{4}{3} which is equal to 3\pi. To find HALF, divide that answer by 2. 3\pi /2= 4.71239, round to the nearest tenth, making the answer 4.7!

2. To find the volume of a rectangular prism you use V=lwh. Input the numbers, V=(30)(12)(16) to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank V=(12)(6)(9) which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.

Given that ABCD is a parallelogram. Find the following
7nadin3 [17]

Answer:

m=8

m<A=83

m<D=97

Step-by-step explanation:

Angles that are opposite of each other in a parallelogram are equal. Knowing this, we can first conclude that angle A and angle C are equal. We can set up the following equation:

9m+11=8m+19

Subtract both sides by 11

9m+11-11=8m+19-11\\9m=8m+8

Subtract both sides by 8m

9m-8m=8m+8-8m\\m=8

To calculate angle A, plug the value of m into its expression.

In a parallelogram, angles that share a side are supplementary, meaning they add up to 180 degrees. Therefore, angle A and angle D are supplementary. Knowing this, we can set up the following equation:

180=83+D

Subtract both sides by 83

180-83=83+D-83\\97=D

I hope this helps!

If philani buys a scooter for 15,000 and wants to pay 15% down then he must pay 2,250. After this they will still need to pay 12,750 to pay of the scooter, but after the 10% annually (for two years) then they will owe 15,750 for the scooter rather than 12,750. Hope this helps!

Your parents decide they would like to install a rectangular swimming pool in the backyard. There is a 15-foot by 20-foot rectan
Lilit [14]

Answer:

  • perimeter: 46 ft
  • area: 126 ft²

Step-by-step explanation:

Since the 3 ft edge is on both sides of the pool, each dimension of the pool is 6 ft shorter than the corresponding dimension of the space. The pool will be 15 ft -6 ft = 9 ft in one direction and 20 ft -6 ft = 14 ft in the other direction.

The perimeter of the pool is the sum of its side lengths:

  P = 9 ft + 14 ft + 9 ft + 14 ft = 2(9 ft +14 ft) = 2(23 ft)

  P = 46 ft

__

The area of the pool is the product of its length and width:

  A = (14 ft)(9 ft) = 126 ft²

The perimeter and area are 46 ft and 126 ft², respectively.
