Find the area of the triangle, then multiply by the depth.
Area = 1/2 x 10 x 12 = 60 square ft.
Volume = 60 x 20 = 1200 ft³
Answer:
23/3 cubic units
Step-by-step explanation:
The volume of a prism is the product of its base area and it height:
V = (23/4 units^2)(4/3 units) = (4·23)/(4·3) units^3 = 23/3 units^3
Answer:
I believe that you are correct in both of the answers
Answer:
10800
Step-by-step explanation:
The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday it was 3600. How many bacteria in the colony at 7 pm?
Step-by-step explanation:
B = B₀ Kⁿ
At 4 pm yesterday the number of bacteria is 400
B₀ = 400
n = number of hrs
at 6 pm yesterday it was 3600 => n = 6- 4 = 2 hrs
B₂ = 3600
=> 3600 = 400 * k²
=> k² = 9
=> k = 3
At 7 Pm Yesterday
n = 7-4 = 3
B₃ = 400 * 3³
=> B₃ = 27 * 400
=> B₃ = 10800
bacteria in the colony at 7 pm = 10800
or B₂ = 3600 & n = 7-6 = 1
Then B₃ = 3600 * 3¹ = 10800
And boom here
Answer:
k=-1/5
Step-by-step explanation:
1/2(10k-16)+11=-2
5k-8+11=2
5k+3=2
5k=-1
k=-1/5
