Teresa stated that the heights of the students in her class were not a function of their ages. Which reasoning could justify Teresa’s statement?A.Two students are the same age but have different heights.
B.Two students have the same height but different ages.
C.No two students are the same age or height.

Answers

Answer 1

Answer:

Option: A is the correct answer.

A. Two students are the same age but have different heights.

Step-by-step explanation:

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.

Hence, option: A is the correct answer.

Which expression is equivalent to 7 2/3⋅7 1/4?

Answers

Answer:

$7^{(11)/(12)}$

Step-by-step explanation:

Rule:

$a^m * a^n = a^(m + n)$

This problem:

$7^(2)/(3) * 7^(1)/(4) =$

$= 7^{(2)/(3) + (1)/(4)}$

$= 7^{(8)/(12) + (3)/(12)}$

$= 7^{(11)/(12)}$

A carpenter is building a fence around a swimming pool. One side of the pool is next to the house and does not need fencing. The carpenter has 120 feet of fencing and plans to use it all. Solve the equation w + 76 + w = 120 to find the unknown dimension of the enclosed rectangular area.a. 12 ft

c. 20 ft

b. 22 ft

d. 18 ft

Answers

The answer is B. 22ft
The equation goes w + 76 + w = 120 so I'm guessing you're solving for w since that's the only remaining side you haven't discovered so first of all collect like terms:
2w + 76 = 120
Secondly minus 76 from the equation to leave 2w on its own
2w - 76 = 120
BUT whatever you do to one side of the equation you have to do it to the side
2w - 76 = 120 - 76
Which will get you to
2w = 44
To get w on it's own you divide the equation by 2 and like before you must do the same to the other side of the equation to balance it out.
w = 44/2
Therefore w= 22ft

Ben wants to leave a 20 percent tip for the waiter at a restaurant. If his meal is $28.53, how much will his total bill be, including the tip? Responses $2.84 $2.84 $5.71 $5.71 $28.53 $28.53 $34.24

Answers

Answer:

$34.24

Step-by-step explanation:

To find the total amount including the tip, you can multiply his total by 1.2. This will add 20% to his total amount, which accounts for the tip:

$28.53*1.2 = 34.236 = $34.24

10 POINTS. 1/7 written as a decimal is 0.142857 (this sequence repeats). What digit occurs in the 2012th spot after the decimal? Please explain.

Answers

1/7 = 0.142857142857142857142857142857142857142857142857142857 and so on

the pattern repeats

the first digit is 1
second digit is 4
third digit is 2
fourth digit is 8
fifth digit is 5
sixth digit is 7

and then the seventh digit is 1, and it repeats

so the six digits repeat again and again...

2012/6 = 335 2/6

It has a remainder of 2, which means that the 12th digit will be 4. because that is the second digit. After going 335 times the 6 digit patterns it will stop at the second digit which is 4.

Your answer is 4.

I hope you understood, it was kind of hard to explain :P
