First convert to feet
3in=3/12=1/4ft
5.5in=5.5/12ft
1:30
multiply scale by 30
1/4ft times 30=30/4=15/2=7.5ft
5.5/12ft times 30=165/12=13.75ft
multiply them
7.5ft times 13.75ft=103.125 ft^2
closest is option D
The cost of 85 shirts is 400+7.5*85=1037.5
The average per shirt is 1037.5/85=12.206
Answer:The sitting fee is 15 dollars
Step-by-step explanation:If you were to use the formula y=mx+b then the starting equation would be y=12x+b. It already gave you the cost for the amount of photos respectively so 51=12(3)+b. 12 times 3 equals 36 and 51 minus 36 equals 15. The same way would be used for 87 dollars and 123 dollars while using the amount of photos respectively. 87=12(6)+b. 12 times 6 equals 72. 72 plus 15 equals 87. 123=12(9)+b. 12 times 9 equals 108. 108 plus 15 equals 123. Therefore the sitting fee is 15. (51=12(3)+15, 87=12(6)+15, 123=12(9)+15)
Answer:
Solution: (2, 2)
Step-by-step explanation:
The first equation describes a line with a y-intercept of 3 and a (downward) slope of -1/2. That is, it has a "rise" of -1 for a "run" of 2.
__
The second equation describes a line with a y-intercept of -2 and an (upward) slope of 2. That is, it has a "rise" of 2 for a "run" of 1.
These two lines meet at the point (2, 2), which is the solution to the set of equation. Those are the values of x and y that satisfy both equations.
Answer:
13.08
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 * 5^2
A =3.14 *25
A =78.5
The angle of the purple sector is 60 degrees
A full circle is 360 degrees
The fraction of the circle that is purple is 60/360 = 1/6
Multiply the area of the circle by 1/6
1/6* 78.5 =13.0833333
Rounding to the nearest hundredth
13.08
