Your grandfather has enjoyed good vision for most of his 80 years. You observe him having trouble reading websites on his new iPad, squinting while he moves it towards and away from his face. You realize he might benefit from reading glasses. Since you were going out anyway, you offer to pick up a pair of glasses for him at the drug store. Consider that your grandfather is at his most comfortable reading posture when he is holding the iPad at a distance of 18 inches.
a. What dioptric power of reading glasses should you get for your grandfather? Note that reading glasses are normally available in increments of 0.25 Diopter.
b. It occurs to you that you could have just shown grandpa how to make the displayed content appear larger on the iPad by adjusting the display "zoom". What percentage zoom (100% is the default view, 200% would make text and images twice as large) would give your grandfather a similar viewing experience to wearing the reading glasses you were planning to purchase?
Answers
Answer:
Step-by-step explanation:
Given that:
The focal point = 18 inches
= (18 × 0.0254)m
= 0.4572 m
= 45.7 cm
For such a comfortable distance of 45.7 cm, the perfect lens power for grandfather can be determined.
Let's recall that, the accommodation amplitude usually decreases with age and eventually becomes 1 D after the age of 50.
Thus, +2.5D or a convex lens appears to be a perfect one.
b. We will agree that Diopter illustrates the optical power or most at times the capability of the lens.
So, 3D is equally 1.75X magnification which is likely to be double the zoom as it will be helpful to the grandfather.
Now, for a 2.5D, approximately 1.5X zooming once(200%) will be perfect and equal to viewing with the reading glasses.

a) Dati cinci exemple de numere intregi mai mici ca zero.
Answers
Answer:
Numerele întregi pozitive sunt toate numerele întregi mai mari decât zero: 1, 2, 3, 4, 5, .... Numere întregi negative sunt toate opusele acestor numere întregi: -1, -2, -3, -4, -5, .... Nu considerăm că zero este un număr pozitiv sau negativ. Pentru fiecare număr întreg pozitiv, există un număr întreg negativ, iar acești numere întregi se numesc opuse. De exemplu, -3 este opusul lui 3, -21 este opusul lui 21 și 8 este opusul lui -8. Dacă un număr întreg este mai mare decât zero, spunem că semnul său este pozitiv. Dacă un număr întreg este mai mic decât zero, spunem că semnul său este negativ.

A newborn turtle has a shell with a 1-inch diameter. The shell keeps a similar shape as the turtle grows. After a year, the shell is 3 inches in diameter. Note: you do not need to know the shape of the shell to complete this question.
1. How many times greater is the volume of the turtle's shell after a year than it was when it was born?
2. How many times greater is the surface area of the turtle's shell after a year than it was when it was born?
Answers
Answer:
I think the volume would be 9 times greater, and the surface area would be 3 times greater
Step-by-step explanation:
Answer:
the volume would be 9 times greater
the surface area would be 3 times greater
Step-by-step explanation:
Because if the shell grows from 1 inch diameter to 3 inch diameter, the surface area will increase 3x more. And the volume I assume is 3x greater because of the height is presumably 3 inches as well.

12a−8−5a+12
Answers
Step-by-step explanation:
Given
12a - 8 - 5a + 12
= 7a + 4
Hope it will help :)
Answer:
7a + 4
Step-by-step explanation:
First, let's rewrite this expression to combine like terms:
12a – 8 – 5a + 12 — I bolded the constants and underlined the expressions with variables
12a – 5a – 8 + 12 — it looks a little easier regrouped, doesn't it?
The last two terms are easy, right?
12 – 8 = 4 — simplify with subtraction
We'll focus on the first two terms now. Let's rewrite the terms with variables attached to make the subtraction easier:
a(12 – 5) = a(7) = 7a
We could also think of it this way: multiplication is just repeated addition.
12a = a + a + a + a + a + a + a + a + a + a + a + a (we just add a to itself 12 times)
5a = a + a + a + a + a (we just add a to itself 5 times)
Subtracting this expression would then look like this:
a + a + a + a + a + a + a + a + a + a + a + a – (a + a + a + a + a)
a + a + a + a + a + a + a + a + a + a + a + a – a – a – a – a – a
Five of the a values will cancel out, and to show this, we can rewrite the expression once more, like this:
a – a + a – a + a – a + a – a + a – a + a + a + a + a + a + a + a
The five a values cancel out and leave us with this:
a + a + a + a + a + a + a
How many a values are added together now? Seven of them, right? We add a to itself 7 times. We can then rewrite that expression as 7a.
Using the [12 – 8 = 4] expression from above, we add the 4 to the 7a to find our final answer: 7a + 4
I hope this helps increase your understanding of the concept! Have a great day!

Solve the equation. n/10+8=15
Answers
Answer:
n = 70
Step-by-step explanation:
n/10 + 8 = 15
n + 80 = 150
n = 150 - 80
n = 70
Answer:
n = 70
Step-by-step explanation:
1) Subtract 8 from both sides of the equation
n/10 + 8 - 8 = 15 - 8
2) Simplify
n/10 = 7
3) Multiply all terms by the same value to eliminate fraction denominators
10 · n/10 = 10 · 7
4) Simplify
n = 70
so your answer is n = 70. Hope that helps!
a rectangle has a length of 8m and a width of 4.5m. A parallelogram has a length of 6 m. The area of the parallelogram is twice the area of the rectangle. What is the height of the parallelogram
Answers
Answer:
12m
Step-by-step explanation:
work out the area of the rectangle then times it by 2 because the parallelogram is twice the area of the rectangle. 8 × 4.5m = 36m². 36 ×2 = 72cm². Now you do 72 ÷ 6 = 12 . the answer is 12m.
The height of the parallelogram is 12 meters.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
The area of a rectangle is given by the formula A = lw, where l is the length and w is the width.
The area of the rectangle is A1 = lw = (8 m)(4.5 m) = 36 m².
The area of a parallelogram is given by the formula A = bh, where b is the base and h is the height.
Since the area of the parallelogram is twice the area of the rectangle, we have:
2A1 = A2
2(36 m²) = 72 m²
So the area of the parallelogram is A2 = 72 m².
We are given that the length of the parallelogram is 6 m, so we can use the formula for the area to solve for the height:
A2 = bh
72 m² = (6 m)h
h = 12 m
Therefore,
The height of the parallelogram is 12 meters.
