It’s obviously -2 because you can’t do 2 positives (2) and (2) to get another positive your going to get a negative so the correct answer is -2
Thickness of the plate before polishing = 2.342
Thickness of the plate after polishing. = 2.087
How much was removed = 2.342- 2.087 = 0.255
Hence , the answer 0.255 which is option B
Answer:
All numbers x such that x > 26
Step-by-step explanation:
W - 10 ≤ 16
W ≤ 16 + 10
W ≤ 26
The numbers that are not part of the solution are all numbers x such that x > 26
Answer:
Below
Step-by-step explanation:
You can use sine law to solve this : sina / A = sinb / B
We will first find side x
We know that since this is a special triangle that side will = 28, but we can prove this mathematically :
sin(45) / 28 = sin(45) / x
= 28 sin(45) / sin(45)
x = 28
Now to find side r just use Pythagorean theorem a^2 + b^2 = c^2 :
c^2 = 28^2 + 28^2
= 1568
Square root this number
r = 39.597
The just round to however your teacher wants
If you didn't already know about special triangles, an isosceles right triangle like this one has a ratio which is the two legs will equal each other, while the hypotenuse is √2a . You could have also used this to solve.
Hope this helps! Best of luck.
