Without calculating, you can immediately see the absolute value sign, which implies that the final result (x) should be positive, not negative.
1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
x+3-1.26923+4.12821 so if I am wrong it took me a while to work this out
Answer:
J < -7
Explantion:
Rewrite so J is on the left side
-20j > 140
Divide each term by -20 and simplify
j < -7
Answer: A
Step-by-step explanation:
Angles opposite shorter sides of a triangle are smaller, and angles opposite longer sides in a triangle are larger.
