Answer:
368 sq. units.
Step-by-step explanation:
We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.
Now, the four isosceles right triangles have one leg equal to 4 units.
Therefore, the area of four triangles = 
sq. units.
Now, we have the area of the given square is (20 × 20) = 400 sq. units.
Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
60 subs
Because it’s 15 per 45 and 45 times 4 is 180 which means that in 3 hours or 180 minutes they sold 15 times 4 amount of subs and 15 times four is 60. Hope this helps. Sorry if the explanation isn’t that good
Answer:
12/15 and 24/30 are equivalent fractions
49 would be in the next space after 42 because this sequence is counting by 7s
Answer:
25/√1658
Step-by-step explanation:
To do that division, you just need to do that simple division. However, let me tell you that the way to do that division, is rationalizating the dividend. This is because in a division, they cannot be any kind of square root. So the mechanical procedure to this is the following:
Start dividing:
25 / √1658
Now, rationalize:
25 / √1658 * √1658 / √1658
This step is to eliminate the square root from the dividend. Then:
25 * √1658 / 1658
Now when you do the math, you should get an accurate result.
