Answer: 66 yards of fence

Step-by-step explanation:

This is a circular enclosure so the length of the fence must be the circumference of the circular enclosure.

The fence was built 10.5 yards from the centre which would mean that 10.5 yards is the radius of the circle.

The circumference will therefore be:

= 2 * Pie * radius

= 2 * 22/7 * 10.5

= 66 yards of fence

The marching band sold gift wrap priced at $4.00 per roll for solid colors and $6.00 per roll for print patterns. If they sold 4
Alex Ar [27]

Answer:

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Step-by-step explanation:

Let

x ---> the number of gift wrap rolls for solid colors sold

y ---> the number of gift wrap rolls for sprint patterns sold

we know that

x+y=480 ---->x=480-y ----> equation A

4x+6y=2,340 ----> equation B

Solve the system by substitution

substitute equation A in equation B

4(480-y)+6y=2,340

solve for y

1,920-4y+6y=2,340

-4y+6y=2,340-1,920

2y=420

y=210

<em>Find the value of x</em>

x=480-y ----> x=480-210=270

therefore

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Question 12<br> Simplify.<br> 54.8-6.9-12<br> 5-2.83.9-4.
trapecia [35]

Answer:

366.

-1493.

Step-by-step explanation:

54.8-6.9-12

You perform the multiplications first:

= 432 - 54 - 12

= 378 - 12

= 366.

5-2.83.9-4

=  5 - 166* 9 - 4

= 5 - 1494 - 4

= -1489 - 4

= -1493
