What approximate focal length of the objective lens will give a total magnification of 200×? assume a length l = 160 mm.

1 answer:

3 0

Considering the data in the question, the focal length of the objective lens that will give a total magnification of 200x is <u>0.8cm focal length.</u>

The whole question is:

You are using a microscope with a 10x eyepiece. What focal length of the objective lens will give a total magnification of 200x? Assume a length L = 160mm.

<h3>How was the answer derived?</h3>

Given that total magnification is 200

And the Assume length is 160

Since we used a microscope with a 10x eyepiece, the magnification would be divided by 10.

=> 200 ÷ 10 = 20.

Also, the focal length is measured in centimeters or meters; we would change the millimeters of focal length to centimeters. Therefore, we have 160 ÷ 10 = 16

The formula for the focal length of the objective lens = assumed length ÷ total magnification.

=> 16 ÷ 20 = 0.8cm.

Hence, in this case, it is concluded that the correct answer is "0.8cm."

A company ordered $400 worth of muffins. Bran muffins cost $2 each and blueberry muffins cost $4 each. If the company ordered tw

astra-53 [7]

Answer:

40 Bran Muffins

80 Blueberry Muffins

Explanation:

Let the number of Bran muffins ordered = x

The number of Blueberry muffins ordered = 2x <em>(it is given that the number of blueberry muffins is twice the number of bran muffins)</em>

<em />

The cost of Bran muffins ordered = Number of Bran muffins * cost of 1 muffin

Cost of Bran muffins ordered = x * 2

Cost of Bran Muffins ordered = $ 2x

The cost of Blueberry muffins ordered = Number of Blueberry muffins * Cost of 1 blueberry muffin

Cost of Blueberry muffins ordered = 2x * 4

Cost of Blueberry muffins ordered = $ 8x

Since the sum of costs of Blueberry and Bran muffins is $400

Cost of Bran muffins + Cost of Blueberry muffins ordered = 400

2x + 8x = 400

10x = 400

x = 40

Hence, the number of Bran muffins ordered is 40

we are told that the number of Blueberry muffins is twice the number of Bran muffins

So,

Blueberry muffins = Bran muffins * 2

Blueberry Muffins = 40 * 2

Blueberry muffins = 80

So, the number of Blueberry muffins is 80
