21/4 is equivalent to...
4 x 5 = 20
so, 21/4 = 5 1/4
5 1/4 = 5.25
5 1/4 = 5 2/8 = 42/8
42/8 = 84/16
Answer:
if the corner is (4x-17)², I believe X would equal 9.644, or if it can be rounded to the tenths place, 9.6, if rounded to the ones place, it'd be 10. I could be wrong, however. I'm not too familiar with this, just wanted to help
Answer:
how high will the ceiling be at the center? ≈43.3 ft above the center
Step-by-step explanation:
standard form of equation for an ellipse with horizontal major axis and center at the origin:
x^2/a^2+y^2/b^2=1, a>b
for given problem:
a=50
a^2=2500
c=25
c^2=625
c^2=a^2-b^2
b^2=a^2-c^2=2500-625=1875
b=√1875≈43.3 ft
≈43.3 ft above the center
That looks like the natural numbers 1 through 10, so ten of them. An odd number less than nine is 1,3,5,7, four of them. If they're equally likely, our probability is
Assuming that the wage of $12.50 an hour applies to Greg and Darius as a team instead of individually, 9 hours of work would have gotten them:
$12.50/hour × 9 hours = $112.50
If they split the wage in half among themselves, then Greg would have
$112.50 ÷ 2 = $56.25
such that if he spent $15 of it (assuming that's the only money he has), he would now have:
$56.25 - $15 = $41.25
∴ Greg now has $41.25.
