Answer:
The area of one slice of pizza is 18 in²
Step-by-step explanation:
First we have to know that the 360 ° representing the circle expressed in radians are expressed as 2π
Now we must calculate the area of the circle
a = π * r²
a = π * (12in)²
a = 144π in²
Now that we have the area of the circumference we multiply it by (π/4) / (2π)
144π in² * (π/4) / (2π) =
144 in² * 1/8 =
18 in²
The area of one slice of pizza is 18 in²
You start with: (assuming x equals the cost to enter and y the cost of going on the rollercoasters.)
x+5y=35
x+11y=59. Multiply the top equation by -1, and subtract the equations, giving you -6y=-24, divide by -6 into both sides of the equation, to get y=4. Now replace y in one of the original equations (I recommend x+5y=35) and solve for x, giving you x=15
The cost for entering is 15 dollars, while each coaster is 4 dollars more. You could simplify this by changing y into x and making it slope-intercept form, to track your cost. y=4x+15, so it has a slope of 4, and a y-intercept of 15. This answer should give you a good grade on a test.
can be simplified to by adding the 7 and 10 to get
.
cannot be simplified any more by combining like terms.
By distributing the 2b into the parentheses, you can simplify the expression:
Here you can just add:
Thus, the only expression that cannot simplify any more using adding like terms is the second,
.
Answer:
50
Step-by-step explanation:
50 / 10 = 5
5 x 3 = 15
