Answer:
5+(-5)=0
-2+2=0
Step-by-step explanation:
First one answer is C.
log3(1/81) = -4
-------------
log(45) / log(2) = 5.4919
answer
A. 5.4919
--------------------
next step
x - 1 = 3x+9
2x - 10
x = -5
answer
D. x - 1 = 3x+9
For this problem you would be solving for the area of 3/4 of a circle with the radius being 24ft. So area of a circle is a= PI R squared so plug in 3.14(24)squared order of operations says to square first so 24 squared is 576. Then PI or 3.14 times 576 equals 1808.64
Now because it is only 3/4 of a circle you wil multiply the answer by 3/4 which is 1,356.48 ft. So the Cow has 1,356.48 Ft of grazing area.
Answer:
a 82°
c 75°
d 150°
f 80°
Step-by-step explanation:
...add all of the given angles, and then subtract the total from 360.
All circles measure 360°.

Answer:
92.5
Step-by-step explanation:
The total of Megan's scores is ...
94 +81 +87 +93 = 355
so her current average is 355/4 = 88.75
The score (s) Megan needs for a 90 average is ...
(2/3)(88.75) +(1/3)s = 90
2(88.75) +s = 270 . . . . . . . . multiply by 3
s = 270 -177.5 = 92.5
Megan needs a score of 92.5 on her final to have an overall average of 90.
