If the number is y then the inequality is
twice the difference of y and 7=2(y-7)
at most- 20=less than or equal to
2(y-7)≤-20

Adult tickets to a play cost $22. Tickets for children cost $15. Tickets for a group of 11 people cost a total of $228. Write an

yaroslaw [1]

Adults = 9
Children = 2

Let x be the number of adults.
11-x is the number of children.

22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.

11 - x = 11 - 9 = 2 number of children.

To check:

22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228

The largest possible circle is cut out of a square whose side length is 6 feet. What will be the approximate area, in square fee

lesya692 [45]

Answer:

$8\ ft^{2}$

Step-by-step explanation:

we know that

The diameter of the largest possible circle is equal to the length side of the square

The approximate area of the remaining board is equal to the area of the square minus the area of the circle

so

$A=b^{2}-\pi r^{2}$

we have

$b=6\ ft$ ------> length side of the square

$r=6/2=3\ ft$ -----> the radius is half the diameter

$\pi =3.14$

substitute the values

$A=6^{2}-(3.14)(3)^{2}$

$A=7.74\ ft^{2}$

Round to the nearest whole number

$A=7.74=8\ ft^{2}$
