Answer:

Mr.Matthews

Step-by-step explanation:

Mr.Matthews: Started at -12

-12 - 8 + 7 - 13 = -20 + 7 - 13 = -13 - 13 = -26

Mr. Peters: Started at -25

-25 + 8 - 6 = -17 - 6 = -23

In this case, -26 is greater than -23.

Mr.Matthews rested at a greater depth.

Hope this helps :)

2. When a < b, how is the graph of x > a and x < b
similar to the graph of x > a? How is it different?

Answers

Answer:

• If the equations of a and b are polynomials,it'll be a curve between a and b [ b<x<a]

• If the equations of a and b are linear,it'll be a line between a and b

Answer:

The correct answer should be B!

Step-by-step explanation:

"A rational number is a number that can be express as the ratio of two integers. ... Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational."

"A integer is any number that is not either a decimal or a fraction (however, both 2.000 and 2/2 are integers because they can be simplified into non-decimal and non-fractional numbers), this includes negative numbers. A whole number is any positive number(0 through infinity) (including non-integers)"

"Common Examples of Irrational Numbers

Pi, which begins with 3.14, is one of the most common irrational numbers. ...

e, also known as Euler's number, is another common irrational number. ...

The Square Root of 2, written as √2, is also an irrational number."

Thus leading me to the conclusion that B is the correct answer!

Sandra calculated the height of a cylinder that has a volume of 576 pi cubic centimeters and a radius of 8 centimeters. Her work is shown below. V = B h Step 1: 576 pi = pi 8 squared h Step 2: 576 pi = 64 pi h Step 3: StartFraction 576 pi Over 64 pi EndFraction = StartFraction 64 pi Over 64 pi EndFraction h Step 4: h = 9 pi cm What error did Sandra make when calculating the height of the cylinder? In step 1, she substituted into the volume formula incorrectly. In step 2, she calculated 8 squared incorrectly. It should be 16 rather than 64. In step 4, the pi should have canceled, making the correct answer 9 cm. Sandra calculated the height of the cylinder correctly.
