Answer is C but can't figure it out.
lapo4ka [179]

Answer:

C. 2,940 ft³

Step-by-step explanation:

The building is composed of a triangular prism and a rectangular prism

Therefore,

Volume of air in the building = volume of the triangular prism + volume of the rectangular prism

Volume of triangular prism = ½*bhl

b = 4 yards = 4*3 = 12 ft

h = 15 - 9½ = 5½ = 5.5 ft

l = 20 ft

Volume of triangular prism = ½*12*5.5*20 = 660 ft³

Volume of rectangular prism = W*H*L

W = 4 yds = 12 ft

H = 9½ = 9.5

L = 20 ft

Volume of rectangular prism = 12*9.5*20 = 2,280 ft³

✔️Volume of air in the building = 660 + 2,280 = 2,940 ft³

A bag contains 11 red chips and 12 blue chips. Two chips are selected randomly without replacement from the bag. What is the pro
Elena-2011 [213]

Answer:

11/23 or 0.478

Step-by-step explanation:

1. Find the probability of selecting 2 red chips:

11/23 * 10/22 = 5/23

2. Find the probability of selecting 2 blue chips:

12/23 * 11/22 = 6/23

3. Add the two probabilities:

5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

hope this helps! <3

Use Long Division to answer number 4. Please show all work!​
skelet666 [1.2K]

Answer:

2x² + 3x + 4 + (17x + 9) / (x² − 4)

Step-by-step explanation:

Start by setting up the division.  Make sure to write all the coefficients, even the zero ones.

x² + 0x − 4 | 2x⁴ + 3x³ − 4x² + 5x − 7

Start by dividing the first term of the dividend (2x⁴) by the first term of the divisor (x²).  That's 2x²; it'll be the first term in quotient.  Multiply the divisor by 2x²:

2x⁴ + 0x³ − 8x²

Subtract that from the first three terms of the dividend:

3x³ + 4x²

Drop down the next term from the dividend, and start the process all over again.

3x³ + 4x² + 5x

When you finish, the quotient will be 2x² + 3x + 4, and the remainder will be 17x + 9.
