Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
The precise name of quadrilateral ABCD is a square because there are 4 sides on a square and the quadrilateral is given has 4 points such as ABCD.
but don't take my word for it is not 100% sure
and I'm so sorry if I'm wrong
Answer:
Tallahassee's Range: 6
Key West's Range: 4
Step-by-step explanation:
To calculate range, you'd subtract the lowest value from the highest value
Tallahassee:
Highest Value: 90
Lowest Value: 84
Range: 90 - 84 = 6
Key West:
Highest Value: 87
Lowest Value: 83
Range: 87 - 83 = 4
Answer:
f(x) = 6
Step-by-step explanation:
The midline of sin(x) is zero, so the midline of f(x) is ...
midline f(x) = 0 +6 = 6 . . . . . . the value of the added constant
For number 1:
10.2 miles. 1/5 is the same as 0.2 so that's how it would be referred to. So the first 0.2 is $0.75 leaving us with 10 miles left. To calculate how many times we add the addition 0.2 mile charge we do 10/ 0.2 = 50. Multiply this 50 by the fare of $0.55 to get $27.50.
Add that $27.50 to the first $0.75 to get $28.25, option A.
For number 2:
Same process. 9.5 miles, first 0.2 miles is $0.75. Leaving us with 9.3 miles left. Rounding to the nearest fifth, I'm guessing that want it to be 9.2 miles. Divide 9.2 by 0.2 to get the amount of times the additional 0.2 mile charge is added, 46. Multiply 46 by the fare charge of $0.55 to get $25.30. Add the first $0.75 charge to get 26.05.
This answer is not up there so I'm going to use the actual 9.3 miles. 9.3/ 0.2 = 46.5. 46.5 * $0.55 = $25.575, call it 25.58. Add the first $0.75 to get $26.32.
Both of these aren't there but they both have $26 in them so I'd go with option B.
