no, since a rectangle requires 90-degree corners, and every angle inside an equilateral triangle is 60-degrees. The only multiple of 90 that you can make is 180-degrees (or any multiple of it).
Answer:
D. R0, 360°
Step-by-step explanation:
Since the transformation is from (x,y) to (x,y), the values stay the same...
It's just like a 360 degrees rotation then, since the end position is identical to the start position.
All other answers would affect at least one of the values to change sign like (-x,y), (x,-y) or (-x,-y)... but a 360 degrees rotation would not.
18 workers
Answer:
4 workers can assemble 12 computers in 9 hours.
Since the number of hours is directly proportional to the number of computers:
4⋅12=48 computers could be assembled by 4 workers in 4⋅9=36 hours.
Since the number of hours is inversely proportional to the number of workers:
48 computers could be assembled by 92⋅4=18 workers in 29⋅36=8 hours.
Write a number as prime factors means to write the number as a product of numbers, all of which are prime. We start by checking whether the number is divisible by prime numbers, starting from the smallest prime number,2.
let's divide 24 into its factors.
first, it's even, so it must divide by 2
24=2*12
12 is also even, so it must divide by 2:
24=2*12=2*2*6
6 is also even, so it must divide by 2:
24=2*12=2*2*6=2*2*2*3
3 is not even, but it's a prime number.
so the solution is
2*2*2*3
