Answer:

Yes

Explanation

You may not trust a 11 year with a phone, but many parents give 11 year old's their own phone. I feel like you should trust them, and they would be responsible enough. I am a 11 year old myself and got my first phone when I was 10. If you don't fully trust them with that privilege buy them a phone that cant have games and can only call and text emergency numbers and your phone number.

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

Viefleur [7K]

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

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."

5. how long is the deck of the bridge? show how you calculated r. (3 points: 2 points for work, 1 point for the solution)

Svetlanka [38]

Based on the construction, the length of the bridge deck is given by r = √(x² + y²) units.

A deck is also referred to as the roadway and it can be defined as the functional area which is designed and developed to allow automobile vehicles and pedestrians to cross highways, valleys, and water bodies.

In order to determine the length of the bridge deck, we would apply Pythagorean's theorem as follows:

r² = x² + y²

Where:

r is the length of the bridge deck.

a is the adjacent side (horizontal distance).

b is the opposite side (rise of the bridge).

Making r the subject of formula, we have:

r = √(x² + y²)

4 t-shirts and a hat costs £31. 00 2 t-shirts and a hat costs £17. 0. How much does a t-shirt cost? how much does a hat cost?.

Elis [28]

Answer:

T-Shirt Cost = £7

Hat Cost = £3

Explanation:

Important Information:

4 t-shirts and a hat costs £31.00

2 t-shirts and a hat costs £17.00.

Here we assume t-shirt be x and hat be y.

Explanation/Solution:

Based on the above information, the calculation is as follows:

4x + y = 31

2x + y = 17

Now subtract equation 2 from 1

2x = 14

x = 7

So y is

4(7) + y = 31

28 + y = 31

y = 3

Therefore we can conclude that The t-shirt cost £7 and Hat cost £3.

3 (x + y) = y If (x,y) is a solution to the equation above and y ≠ 0, what is the ratio of x/y

Fofino [41]

Answer:

x/ y = -2/ 3

Explanation:

we have:

3(x + y) = y

distributing 3 within the parenthesis:

=> 3x + 3y = y

taking y to the other side, changing its sign in the process

=> 3x = y - 3y

=> 3x = y(1 - 3)

=> 3x = -2y

you can represent any integer as a fraction by putting a "1" in the denominator

$\implies \mathsf{ \frac{3x}{1} = - \frac{2y}{1} }$

taking y to the denominator on the LHS and 3 to the denominator on the RHS

$\implies \mathsf{ \frac{x}{y} = - \frac{2}{3} }$

that makes the ratio, x/y = -2/ 3
