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) <u><em>Factorized form:</em></u>

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

b) Given that r = 0.14%

<em>Putting in the above formula</em>

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

A = 400(10,014)

A = 4,005,600

Mai wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with length 6 m and width 2 m. She decides on a sca

BigorU [14]

Answer:

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = $\frac{1}{40}$ units of scale

6 m of kitchen = $\frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm$

Length of scale = <em>15 cm</em>

40 units of kitchen = 1 unit of scale

1 unit of kitchen = $\frac{1}{40}$ units of scale

2 m of kitchen = $\frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm$

Width of scale = <em>5 cm</em>

<em></em>

Please refer to the attached image as well for representation of given scale.

Tim and Luke start a lawn-mowing business and buy a lawnmower for $325. They plan to charge $25 to mow one lawn. Which inequalit

bonufazy [111]

lawnmower = 325 USD

lawn mowing = 25 / lawn

total profit >= 1000 USD

x = number of lawns

25x - 325 = 1000

25x = 1000 + 325

x = 1325 / 25

x >= 53 lawns

25(53) >= 325 + 1000

The answer is D.

Model = $\dfrac{1}{100}$ of the actual size

$=\dfrac{1}{100}\times 305$

$=3.05$

Therefore, the height of the model of statue is 3.05 feet.
