B.28.1
Answer:
4th option
Step-by-step explanation:
She purchased a DVD for $28.
$50 - $28 = $22
1. 22 < 22
2. 22 > 22
3. 22 < 78
4. 22 > 78
I would say it would be the 4th option because she can only spend less than 78.
I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.
Answer:
60
Step-by-step explanation:
let's say the angle is x
tan x=2√21/2√7=1.73205...
tan inverse of it = 60
When you raise a exponent to an exponent, multiply exponents.
When you multiply powers with the same base add exponents.

Answer:
The area of this hub cap is about 470.46 square centimeters.
Step-by-step explanation:
Circumference (C) = 2π radius
Replacing with the values given:
76.87 = 2 (3.14) r
Solving for r (radius)
76.87/ (2x 3.14) =r
r = 12.24 cm
To find the Area:
Area of a circle = π r^2
A = 3.14 (12.24)^2
A = 470.46 cm2
If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.
