Scientists can estimate the number of bacteria in a refrigerated food using the formula 0.26=

monitta

Time is C. 50 seconds

Step-by-step explanation:

The population of bacteria at time t here is given by

$0.2b=\frac{t^2}{20}$

where

b is the number of bacteria

t is the time in seconds

Here we want to find the approximate time at which the number of bacteria is

b = 625

Substituting into the equation and solving for t, we find:

$t^2=20\cdot 0.2 b\\t=\sqrt{4b}=\sqrt{4\cdot 625}=50 s$

Therefore, the solution is

C. 50 seconds

Zoey has 99 years .She plans to make 5 bangles .Each bangle is made using 30 beads how many more beads does zoey need?

drek231 [11]

Note: I am assuming you meant to say:

Zoey has 99 beads instead of 99 years.

Answer:

Zoey needs 51 more beads to make 5 bangles.

Step-by-step explanation:

Total number of beads Zoey currently has = 99 beads

Beads need to make one bangel = 30 beads

Beads need to make 5 bangles = 30 × 5 = 150 beads

Since she has already 99 beads.

So, all we need s to subtract 99 beads from 150 beads.

Therefore,

The number of beads Zoey needs = 150 - 99

= 51 beads

Thus, Zoey needs 51 more beads to make 5 bangles.
