500=4πr^2. first divide 500 from four which will equal 125, then divide 125 with π and it will equal 39.788 . finally √39.788. the answer will be r=6.3 or 6
For b on the first paper you will start with the distribution property and multiply both x and 2 by 3 because they are in the ()
now you have 3x+ 6=x-18
from here you can subtract x from both sides
2x+6=-18
next subtract 6 from both sides
2x=-24
divide both sides by 2...
x=-12
hope this helped
Decrease because you taking something off of something
Answer:
Maria is 66" tall, Juan is 51" tall
Step-by-step explanation:
There are 12 inches to a foot.
Luis is 62" tall
Maria is 1/3 of a foot taller than Luis, 1/3 of 12 is 4, (multiply 12 by 1/3)
So Maria is 4 inches taller than Luis, making her 66" tall
Juan is 1 1/4 feet shorter than Maria, that's one foot and 1/4 of a foot shorter, 1/4 of 12 is 3 (multiply 12 by 1/4)
So Juan is one foot (12 inches) plus 3 more inches shorter than Maria,
Juan is 15 inches shorter than Maria, making him 51" tall
