The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacter

Drupady [299]

Answer:

f(x) = 50000*2^x
3 days

Step-by-step explanation:

Given:

Initial amount of bacteria = 50000
Growth rate = 2 times a day

Required equation:

f(x) = 50000*2^x

Solve for x:

400000 = 50000*2^x
2^x = 400000/50000
2^x = 8
2^x = 2^3
x = 3

After 3 days bacteria numbers will reach 400000

What is one tenth of two hundred

matrenka [14]

First you have to convert 1/10 into a decimal:
1/10= 0.1
Multiply 0.1 by 200:
0.1x200=20
So, 20 is 1/10 of 200.

Find the surface area. PLEASE HELP!!!!!

jonny [76]

Since it is a cube, all sides lengths are the same.

Surface area = 2lw+2lw+2hw
if you substitute all the sides for 13 you get
2(169) three times
so you multiply and get 338 three times so you do 338x3 which is 1014 cm

its messy to explain so i attached a photo

The supplement of an angle is three times the measure of the angle.

stira [4]

Answer: The angle equals 45 ∘ and the supplement is 135 ∘

Explanation:

Since the supplement is three times the angle, we can say s = 3 a

Since we know the supplement is

180 − a , we can plug that in.

180 - a = 3a

180 = 4 a (add a to both sides)

45 = a (divide both sides by 4)

Since we know the angle now, all we have to do is multiply it times 3 to find the supplement.

45 × 3 = 135
