Hello,
Answer B
=-3s^6t²+6st^9-6t^7
Answer:
12.56
Step-by-step explanation:
area of a circle is A=πr^2
radius is 2
a= 3.14 (2)^2
=3.14 x 4
=12.56
Answer:
x=y
Step-by-step explanation:
-let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:
-Hence, for each one tennis ball, there is a tennis racket.
#This is a direct linear relationship and is modeled as graphed in the attachment:
a=9.2
b=1 5/8
c=4
d=24
e=2.3
f=8.5
g= 2.6
First, turn these mixed numbers into improper fractions,
and
. Next divide, which you do by flipping the second fraction and multiplying.
. If necessary, you could also turn this into a decimal, roughly 9.647, or back into a mixed fraction,
.
