Normal vision is called 20-20 vision. These numbers are actually a ratio—a comparison of the distance you can see to the distance a normal-sighted person can see. For example, a person with 20-30 vision can see from a distance of 20 feet what a person with 20-20 vision can see from a distance of 30 feet. Based on this knowledge, explain what the following numbers mean regarding vision.
a. 20-100
b. 20-40

Answers

Answer 1

A person with 20-40 vision can see up to 30 feet and a person with 20-100 vision can see up to 200 feet (No-one can see that far unless they are not human or unless they are a spirit.)

Find the volume of a right circular cone that has a height of 17 m and a base with a circumference of 6.3 m.

Answers

Answer:

The volume of the right circular cone is approximately 17.9 m³

Step-by-step explanation:

The given parameters of the cone are;

Height = 17 m

Circumference of the base, C = 6.3 m

The circumference, C, of a circle is given by the formula, C = 2×π×r

Therefore, we have;

C = 6.3 m = 2×π×r

r = 6.3/(2 × π) ≈ 1.002676

The volume, V, of a cone is given by the following formula;

[tex]V = \dfrac{1}{3} \times \pi \times r^2 \times h[/tex]

Where;

r = The radius of the base ≈ 1.002676

h = The height of the cone = 17 m

[tex]V = \dfrac{1}{3} \times \pi \times 1.002676^2 \times 17[/tex]

V = 1/3 × π × (1.002676 m)² × 17 m ≈ 17.89776 m³ which by rounding up to one decimal place is 17.9 m³

The volume of the right circular cone, V ≈ 17.9 m³.

Karen purchased a prepaid phone card for $15. Long-distance calls cost 19 cents a minute using this card. Karen used her card only once to make a long-distance call. If the remaining credit on her card is $12.91, how many minutes did her call last?

Answers

Answer:

I am pretty sure the answer is 11 minutes and the cost was $2.09

Step-by-step explanation:

Ihope this helps you:)

Step-by-step explanation:

Ok so we start with $15 now the remaining amount is $12.91, so let's substract

15.00 - 12.91 = 2.09

Alright now I must work with this number, since every minute used on the call is 19 cents, i must divide 2.09 to see how many 19 cents fit into this number

2.09 / 0.19 = 11

So she lasted talking or in this call 11 minutes....

2 5/6 years is how many months

Answers

2 5/6 years Is 34 months

Final Answer: 34 months

Steps/Reasons/Explanation:

Hey there! Each year is 12 months. We can see that 2 years is already given. 2 years × 12 months = 24 months.

For [tex]\frac{5}{6}[/tex] we will multiply it by two to find the remaining amount of months. [tex]\frac{5}{6}[/tex] × [tex]2[/tex] = [tex]\frac{10}{12}[/tex]. This means that there is an extra 10 months of a year remaining.

Now we have to add them up. 24 months + 10 months = 34 months.

To find:

The range of the given function.

Solution:

We know that, range is the set of output values.

From the given table it is clear that, hours of training is the input variable and pay per month is the output value.

So, range of the given function is the set of pay per month.

Range = {1100, 1200, 1300, 1400, 1500, 1600, 1700}

Therefore, the correct option is A.

Step-by-step explanation:

Please find the complete question in the attached file.

The total payment  = y

The number of copies to be sold = x

[tex]\to y = 70x + 2200[/tex]

In part (a):

Change of pay = discrepancies between (x+1) sale and (x) sale of copies for every copy sold

[tex]=[70(x+1) + 2200] - [70x + 2200] \\\\= 70x + 70 + 2200 - 70x - 2200\\\\= 70\\\\[/tex]
