Answer:
x ≈ 34.88 square cm
Step-by-step explanation:
Solve by proportional formula:
Area of a sector/area of circle* = sector central arc measure/360
*area of a circle = πr²
x/(53.29π) = 75/360
x/53.29π = 0.2083
x = 11.1020833π
x = 34.8782233
x ≈ 34.88 square cm
If I'm interpreting this right, it's -36 since a half times ten is 5... so it comes down to 5-41 which equals -36.
Answer:
y = 6/7
Step-by-step explanation:
The equation given is:
-3 = 7(y - 9/7)
To solve this, we will expand the bracket and afterwards, collect like terms:
-3 = (7*y) - (9/7 * 7)
-3 = 7y - 9
Collecting numeric terms to the left hand side:
-3 + 9 = 7y
=> 6 = 7y
=> y = 6/7
That is the solution.
