What is the value of 23 divided by three when rounded to the teeth

Normal vision is called 20-20 vision. These numbers are actually a ratio—a comparison of the distance you can see to the distanc

kompoz [17]

Answer:

See below.

Step-by-step explanation:

a. A person with 20-100 vision can see from a distance of 20 feet what a person with 20-20 vision can see from 100 feet.

b. If you have 20-40 vision you can see from 20 feet what a person with 20-20 vision can see from 40 feet.

The table below shows the number of tadpoles in a pond after a certain number of months.

aliya0001 [1]

<h3>Answer: Choice D) 6 months to 10 months</h3>

===================================================

Explanation:

x = number of months
y = number of tadpoles

Highlight the rows that correspond to 6 months and 10 months.

This leads to the two points (6,330) and (10,460).

Apply the slope formula. This is because the slope is the average rate of change.

m = (y2-y1)/(x2-x1)

m = (460-330)/(10-6)

m = 130/4

m = 32.5

This is the average rate of change from month 6 to month 10.

Let A = 32.5 so we can compare it later.

---------------------------

Now let's focus on months 4 and 8

We get the two points (4, 300) and (8, 410)

Use the slope formula again

m = (y2-y1)/(x2-x1)

m = (410-300)/(8-4)

m = 110/4

m = 27.5

Let B = 27.5

--------------------------

For the third answer choice, we have the points (2,240) and (8,410)

Once again, use the slope formula.

m = (y2-y1)/(x2-x1)

m = (410-240)/(8-2)

m = 170/6

m = 28.33 approximately

Let C = 28.33

--------------------------

Lastly for choice D we have the points (4,300) and (10,460)

So,

m = (y2-y1)/(x2-x1)

m = (460-300)/(10-4)

m = 160/6

m = 26.67 approximately

Let D = 26.67

--------------------------

To recap everything, we found these four average rates of change for choices A through D

A = 32.5
B = 27.5
C = 28.33 (approximate)
D = 26.67 (approximate)

We see that A is the largest of that group. Therefore, the greatest average rate of change of that group is from month 6 to month 10. This is why choice A is the final answer.

Find the area of the composite figure 10 ft 4 ft 3 ft 6 ft square feet

mina [271]

Answer:

Exercise Problem Solution

1 Find the perimeter of a triangle the sides of which are 10 in, 14 in and 15 in. P = 10 in + 14 in + 15 in = 39 in

2 A rectangle has a length of 12 cm and a width of 4 cm. Find its perimeter. P = 12 cm + 12 cm + 4 cm + 4 cm = 32 cm

3 Find the perimeter of a regular hexagon with each side measuring 8 m. P = 6(8 m) = 48 m

4 The perimeter of a square is 20 ft. How long is one side? 20 ft ÷ 4 = 5 ft

5 The perimeter of a regular pentagon is 100 cm. How long is one side? 100 cm ÷ 5 = 20 cm

Monica [59]

Question 1:

–6 + x = –3

x = -3 + 6

x = 3

Hence, the answer is C.

Question 2:

–2a + 2a + 7 = 8

7 ≠ 8

Hence, the answer is C.

Question 3:

2(2y – 16) = 0

4y - 32 = 0

4y = 0 + 32

4y = 32

y = $\frac{32}{4}$

y = 8

Hence, the answer is C.

Question 4:

5p – 4p – 8 = –2 + 3

p - 8 = 1

p = 1 + 8

p = 8

Hence, the answer is A.

Question 5:

4n – 2n + 4 = –1 + 17

2n + 4 = 16

2n = 16 - 4

2n = 12

n = $\frac{12}{2}$

n = 6

Hence, the answer is A.

Question 6:

2(4z – 3 – 1) = 166 – 46

8z - 6 - 2 = 120

8z = 12 + 8

8z = 20

z = $\frac{20}{8} = \frac{10}{4} = \frac{5}{2}$

z = 2.5

Hence, I think the question is wrong; it is missing a variable.

Question 7:

–x = 3 – 4x + 6

-x + 4x = 3 + 6

3x = 9

x = $\frac{9}{3}$

x = 3

Hence, the answer is C.

Question 8:

4n + 6 = 4 + 2 + 4n

4n - 4n + 6 = 6

6 = 6

Hence, the answer is C.

Question 9:

6y + 4 = 8 + 2y + 2y

6y - 4y = 8 - 4

2y = 4

y = $\frac{4}{2}$

y = 2

Hence, the answer is B.

Question 10:

3(2x – 4) = 8 + 2x + 6

6x - 12 = 14 + 2x

6x - 2x = 14 + 12

4x = 26

x = $\frac{26}{4} = \frac{13}{2}$

x = 6.5

Hence, the answer is A.

Question 11:

z – z + 1 = z + 1

1 = z + 1

z = 1 - 1

z = 0

Hence, the answer is B.

Question 12:

3.6m – 2.7 = –1.8m

3.6m + 1.8m = 2.7

5.4m = 2.7

m = $\frac{2.7}{5.4} = \frac{1}{2}$

m = 0.5

Hence, the answer is B.
