Answer:

Factored Equation:

A = 4,000,000(1 + r)

If r = 0.14%, the number of bacteria after one hour is calculated by:

4,000,000(1 + 0.14/60)

= 4,000,000(1.002333)

= 4,009,332

After one hour, the petri dish will have produced 4,009,332 bacteria at a growth rate of 0.14%.

Side note: I don't even know if this is right. I just went with what I have.

Answer:

a) Factorized form:

A = 4,000,000 (1+r)

b) Given that r = 0.14%

Putting in the above formula

A = 4,000,000( $\frac{10,000+14}{10,000}$ )

A = 400(10,014)

A = 4,005,600

Please help me with this problem

Answer:

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Step-by-step explanation:

Equations

We are given some conditions applying to the internal angles on a triangle ABC.

The measure of angle A is 13 less than the measure of angle C.

The measure of angle B is 11 less than 4 times the measure of angle C

Let x = measure of angle C

The first conditions states:

$m\angle A = x-13$

The second conditions states:

$m\angle B = 4x-11$

The sum of all angles must be 180°, thus:

$x - 13 + 4x - 11 + x = 180$

Simplifying:

6x -24 = 180

Adding 24:

6x = 204

Dividing by 6:

x = 204/6

x = 34

$m\angle C = x = 34^\circ$

$m\angle B = 4x-11 = 4*34-11 = 125^\circ$

$m\angle A = x - 13 = 34 - 13 = 21^\circ$

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Esma has a box that is 20 cm wide 10 cm high, and 10 cm deep she wants to fill the box with packages that are 5 cm wide 2 cm hig

anastassius [24]

Answer:

Esma can fit 3 packages in the box because 20+10+10=30 and 5+2+2=9 so if you add up 9 three times you get 27 and that is the closest number you can get before going over.
