We know that the area of each tile is 3 1/2in^2
All we need to do is divide.
210 / 3.5 = 60
So, she will need 60 tiles to cover the entire bathroom floor.
Best of Luck!
X is the easy one to solve here. A triangle must have 180 degrees. Add 90 to 38 and subtract that value from 180. This results in x = 52 Degrees. Y is a little bit more difficult. Because The two lines are parallel, Angle CDB is equal to the angle just above y-12. That angle is equal to x, in other words. This angle and y-12 must equal 180 when they are added together, as this is the value for degrees of a line. So, 180= (y-12) + 52. Just solve this algebraically, and is should result in y = 140 degrees.
Tldr: y = 140, x= 52

A
Slope intercept form is y=mx+b. Plug in the m to make the equation y=6x+b. Then plug in the b to make the equation y=6x+4.2.
Answer:
The probe's final position is -143m
Step-by-step explanation:
Note that the words 'lowered' and 'below' mean subtract; while the word 'raised' means add. Thus, interpreting the statement to mathematical expression is done below.
![- 90m + 50m - 138m + 35m](https://tex.z-dn.net/?f=%20-%2090m%20%2B%2050m%20-%20138m%20%2B%2035m)
![= - 143m](https://tex.z-dn.net/?f=%20%3D%20%20-%20143m)
Therefore, the probe's final position is -143m. Hence, the sensor is 143m below the sea level.
