An acute angle is an angle that is less than 90*. so, assuming that they are talking about a normal sheet of paper and a normal window, both are out. 

Knives pointed end is right.
Scissors as wide as they can go will be an obtuse angle so no.
A sharpened tip of a pencil will be correct.

D and E. An acute angle is any angle that is less than 90(a right angle). A is an obtuse angle(more than 90). And B + C are right angles. Hope this helps you!

Ghella [55]

Answer:

  it is NOT possible

Step-by-step explanation:

A number is divisible by 6 if it is even and divisible by 3. It is divisible by 3 if the sum of digits is divisible by 3.

The sum of digits of 152 is 1+5+2 = 8, which is not divisible by 3, so 152 is not divisible by 6.

Someone Please Help Me. I don't understand how to do this.
Tamiku [17]
[1] The median to the base passes through the top point (0,b) and the bottom point (0,0) since it is going straight down. The slope formula is
\frac{y_2-y_1}{x_2-x_1}
So, the slope of the median is (b-0)/(0-0) = b/0. Technically, this is undefined, but let's leave it this way for now.

[2] The base passes through the left point (-a,0) and the right point (a,0). Its slope must be (0-0)/(a-(-a)) = 0.

[3] We now check if the slopes are negative reciprocals. Flipping b/0 over and putting a negative sign gives:
b/0 -> - 0/b = 0
So the slopes are negative reciprocals, which means the lines are perpendicular.

A 4-oz. filet of salmon contains 500 mg of potassium. The daily recommended amount of potassium is 3,500 mg. If you ate a 6-oz.
Lyrx [107]
The answer is 21% because a 6-oz fillet of salmon contains about 750 mg of potassium. 3500-750 equals 2750, meaning that whichever percent closest to that answer is correct. 3500 - 21% = 2760 which is the closest number to the correct percentage therefore A. Is the answer.
