Answer:
Amaya is wrong.
Step-by-step explanation:
The perimeter of the square is 20 inches, which means each side of the square needs to add up to 20 inches. If the side length of that side Amaya pointed out is 4 inches, then the total perimeter would only be 18 inches, in another case, if they were talking about the area of the square/rectangle (now), it would be 20 inches. So, Amaya is wrong.
Answer:
Option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Step-by-step explanation:
Given that c=the number of cars in a parking lot.
The phrase given is "the sum of the number of cars and 9"
To find the algebraic expression which represents the given phrase :
The algebraic expression to the given phrase is c+9
That is option C) c+9 is correct
The sum of the number of cars and 9=c+9 is correct algebraic expression representation for given phrase
Answer:
The radius of a hexagon is called the apothem, which in this case is 15.
We need to know the side length which is found by the equation:
side length = apothem * 2 * (tan (180 / #sides))
side length = apothem * 2 * (tan (180 / 6))
side length = 15 * 2 * (tan (30 degrees))
side length = 30 * .57735
side length = 17.3205
We need the perimeter of the hexagon which equals the side length times six.
perimeter = 6 * 17.3205 = 103.923

Step-by-step explanation:
The x- intercept is the value of x where the line crosses the x- axis.
The x- intercept is (0.3, 0)
The y- intercept is the value of y where the line crosses the y- axis
The y- intercept is (0, 0.4)
Answer:
68
Step-by-step explanation:
1) Plug In (when you plug in you replace the defined variable with the number given. usually you have to find the numbers to plug in but since they're already given to you you just plug them in.) 4(3) + 8(7)=T T= total cost
2) Multiply 4*3=12 8*7=56
3) Add 12+56=68
4) <u>T=68</u>
