Area of circle = <span>πr^2
r = 7/2 = 3.5
r^2 = 12.25
Area = 12.25</span><span>π in^2</span>
I'll help with 1.)
9m:3m = 6m:x
cross multiply
9x=3*6
9x=18
divide both sides 9
x = 2
the missing side is 2m
The missing angle is 30°
Question 2.)
find the ratios to solve for missing side
24:6 = b:4
cross multiply
24*4 = 6b
96 = 6b
divide both sides by 6
16 = b
The missing angle is 32°
Question 3.)
Find missing side d
make a ratio
5:d = 3:9
cross multiply
5*9 = 3d
45 = 3d
divide both sides by 3
15 = d
the missing angle is 90°
Question 4.)
Find missing side s
write as proportion or ratio
36:6 = s:2
cross multiply
36*2 = 6s
72 = 6s
divide both sides by 6
s = 12
The missing angle t is 71°
Hope this helps :)
Answer:
you just need to replace the number into x
Step-by-step explanation:
for example:
f(-4) 1+3x
=1+3(-4)
= -11
Hello
the answer is d
have a nice day
The answer would be (C).
To be fully simplified, the numerator and denominator must have a GCF of 1.
Answer (C) says 3/57. However, using the divisibility rule of 3 (add the digits together, and if the sum is a multiple of 3, then the number is as well), we see that 57 is divisible by 3, meaning this fraction is not simplified. The simplified version would be 1/19.
