21 students because if 6 represents 30% u add 6 two more time which equals 18 and 90% then u add 3 more because it is half of 6. when u add 3 more u will get 21 and 100%
Here is the set using D = rt.
Jet 1:
rate = 377 mph
time = x
Distance = 9128 miles
Jet 2:
rate = 275 mph
time = x
Distance = 9128 miles
Equation:
377x + 275x = 9128
You finish.
The simpliest form is 71/10, the fraction
Step-by-step explanation:
Since this isn't a really small (1/1000000000) or really big (like the radius of the earth) number you don't need the standard notation, so the fraction 71/10 is the simpliest because there is only a decimal, so it can be a fraction of ten.
Answer:
The answer is A
Step-by-step explanation:
The reason A is correct is because all of the other transformations change the size of the triangle, and A is the only answer that only reflects the image over the y axis without changing it, thus making it similar to the preimage
