Answer:
All pencils down, turn in your tests, put them in a stack on my desk" ordered the professor to the class of 200 students.
Almost every student put their pencil down except for one student who was adding to their last answer. When the other students had handed in their tests the late student walked up to the professor's desk.
"You failed" exclaimed the teacher. "You didn't put down your pencil in time and you have failed this test."
Suddenly the late student became indignant. "Do you know who I am?! DO YOU KNOW WHO I AM?!"
"Frankly, I do not nor do I care" the professor countered.
So the late student stuck his test into the middle of the stack of papers and walked out of the room.

Answer:
Length of the Rectangle = 10 inches
and Width = 25 inches
Step-by-step explanation:
Let the width of the rectangle = k inches
So, the Length of the rectangle = (3k - 5) inches
Perimeter = 70 inches
Now, Perimeter of the Rectangle = 2(Length + Width)
= 2 (k + (3k-5))
⇒ 2 (k + (3k-5)) = 70
or, 2(k + 3k -5) = 70 ⇒ 2(4k - 5) = 70
⇒ 8k - 10 = 70
or, 8k = 70+ 10 = 80
or, k = 80/8 = 10
So, the Length = 10 inches
Hence, Width = 3k - 5 = 3(10) - 5 = 30 - 5 = 25 inches
So, Length of the Rectangle = 10 inches
and Width = 25 inches
Answer:
∠1 = 58°
∠2 = 122°
∠3 = 122°
Step-by-step explanation:
∠1 = 58°
∠2 = ∠3
∠2 = (360 - 58 - 58)/2 = 122°
∠3 = 122°
Answer:
= 2(1 - 2h)
Step-by-step explanation:
Given that:
=3(2−0.9h)+(−1.3h−4)
Simplifying:
=(6 - 2.7h) + (-1.3h - 4)
Removing brackets
=6 - 2.7h -1.3h - 4
Adding like terms (h terms and constants)
= 2 - 4h
We can take 2 common as:
= 2(1 - 2h) Required sum
