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:
therefore the second bouquet will have more flowers , as it will have 25 daisies
Step-by-step explanation:
3 roses for every 5 carnations
5 daisies for every 4 carnations
we can solve this using cross multiplication
3 : 5
x : 20
5x = 60
x = 60/5
<em>x = 12</em>
meaning that for a bouquet that has 20 carnations there will be 12 roses
5 : 4
x : 20
4x = 100
<em>x = 25</em>
meaning that for a bouquet that has 20 carnations there will be 25 daisies.
<u>therefore the second bouquet will have more flowers , as it will have 25 daisies</u>
She is not correct.
The GCF for 2x^2 + 4xy + 8xy^4
is 2x
The first term does not have a 'y' in it so you cannot have a 'y' in the GCF.
The second and third terms both only have 1 'x', so you can only take out 1 'x', not 2.
The highest constant that all three terms have in common is a 2.
- 6+t=6+t
- y+11
- 12-4=8
- 7/t
- 25-19=6
- 2s+s
- 11-r
- 2s+6x
- x/17-(12+2)
- 3+(x-10)
- (7+2)/2
- x-13
Hope this helps and have a BLESSED DAY! I also put some charts with my answer to help you better understand it!
