A sector has an area of 50 ft sq, and a central angle of 45 degrees. Find the radius.
Answers
Answer:
Step-by-step explanation:
45° is 1/8 of a circle, so the area of the sector is 1/8 the area of the circle.
Area of circle = 8*50 = 400 sq ft
πr² = 400
r = √(400/π) = 20/√π ≈ 11.3 ft

Follow Order of Operations (PEMDAS):
Parentheses, Exponents, Multiplication/Division, Addition/Subtraction
a. 9 + 4² - (4-2) • 4
9 + 4² - (4-2) • 4 –––Start with (4-2) = 2 (parentheses)
9 + 4² - 2 • 4 ––– 4² (exponents)
9 + 16 - 2 • 4 ––– 2 • 4 (multiplication)
9 + 16 - 8 ––– 9 + 16 (addition)
25 - 8 ––– 25 - 8 (subtraction)
17
b. 15 - 4 + 2(7-3) • 5
15 - 4 + 2(7-3) • 5 ––– Start with 2(7-3)
~ Note: this can be done using distributive property (2•7 - 2•3) OR solving the parentheses first and then multiplying 2(4). Both get 8 and same end result.
15 - 4 + 8 • 5 ––– 8 • 5 (multiplication)
15 - 4 + 40 ––– 15 - 4 (subtraction) *Note: Subtraction and addition are interchangeable in the order because you do it left to right*

Answers
9514 1404 393
Answer:
(5, 8)
Step-by-step explanation:
The circumcenter of a right triangle is the midpoint of the hypotenuse.
O = (A +C)/2
O = ((2, 6) +(8, 10))/2 = (2+8, 6+10)/2
O = (5, 8)
The circumcenter is (5, 8).

Answers
Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
