Step-by-step explanation:
$52.45
49.95×.05
then add that result to 49.95= answer
Answer:
C≈62.83
Step-by-step explanation:
Use the formula C=πd
Plug in 20 for d and simplify
You then get 62.8318530718 in a calculator
So, you round it to 62.83
Answers:
5. x = 1
6. y = 11.5
Step-by-step explanation:
For question 5, you can use power of a point which describes the relationship of two secants intersecting inside a circle. You get the formula:
AC * CD = BC * CE
You can substitute the values you are given to get:
2 * 4 = x * 8
This gives you x = 1
For question 6, you can use another formula in power of a point that describes two secants intersecting in the exterior of a circle. You get the formula:
GH * GJ = GI * GK
Using segment addition postulate, you get:
GJ = GH + HJ = 5 + 16 = 21
GK = GI + IK = 6 + y --> y + 6
Now, substitute into the equation from power of a point:
5 * 21 = 6 * (y + 6)
105 = 6 * (y + 6)
17.5 = y + 6
y = 11.5
Answer:
x < -7
Step-by-step explanation:
-4x > 28
-x > 7
x < -7
Yes here is an example:_
x/4 + 5/6 = 2
The LCD of 4 and 6 is 12 but we can also multiply through by 24 to clear the fractions:-
x/4 * 24 + 5/6 * 24 = 2 + 24
6x + 20 = 40
This will give us the same result if we multiplied through by 12.
