To find the circumference of this circle, you need to use the formula C=2(3.14)r
which means circumference=2 times pi times the radius so, you would multiply 2.8(the radius of your circle) times 2. Then you would multiply that times 3.14(pi rounded to the nearest hundredth). And there u go. U have ur answer.
C=2(2.8)(3.14)
C= 5.6(3.14)
C=17.584
C=17.58 feet
F(x) = 2 x - 5
15 = 2 x - 5
2 x - 5 = 15
2 x = 15 + 5
2 x = 20
x = 20 / 2
x = 10
hope this helps!
Y=6x-27...........(1)
y=4x-17...........(2)
By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.
Answer:
A.) 132.3 mm Hg
B.) 49 years old
Step-by-step explanation:

P = blood pressure
y = age in years
A.) Solution
To find: P
Given: y = 48

P = 0.006 x 48 x 48 - 0.01 x 48 + 119
P = 0.006 x 2,304 - 0.48 + 119
P = 13.824 - 0.48 + 119
P = 132.344 ⇒ 132.3
B.) Solution
To find: y
Given: P = 132.92

Answer: 49 years old
Answer:
28.26 inches
Step-by-step explanation:
The circumference of a circle is
, where d = diameter. In this case, we use pi as 3.14 and the diameter as 9.
Therefore, the answer is 28.26.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
