Answer:

x = -9

Step-by-step explanation:

The value 13-8x apparently is the measure of the arc in degrees. That is the same as the measure of the central angle, shown as 85°. Then we have ...

85 = 13 -8x

72 = -8x . . . . . . subtract 13

x = -9 . . . . . . . . divide by -8

The value of x is -9.

a town park has 2 biking trails. Marsh Trail is 5 and three over ten miles long. Woodland trail is 2 and 4 over 5 miles long. Ho

Marsh Trail is longer than Woodland trail by 2.5 miles

Step-by-step explanation:

A town park has 2 biking trails

1. Marsh Trail is 5 and three over ten miles long

2. Woodland trail is 2 and 4 over 5 miles long

We need to find that Marsh Trail is how much longer than

Woodland trail

To do that we will subtract the length of the Woodland trail from the

length of the Marsh Trail

∵ The length of Marsh Trail is 5 and three over ten miles

- 5 and three over ten = $5\frac{3}{10}$

∵ $\frac{3}{10}$ = 0.3

∴ $5\frac{3}{10}$ = 5.3 miles

∵ The length of Woodland trail is 2 and 4 over 5 miles

- 2 and 4 over 5 = $2\frac{4}{5}$

∵ $\frac{4}{5}=\frac{4*2}{5*2}=\frac{8}{10}$ = 0.8

∴ $2\frac{4}{5}$ = 2.8

∴ The difference = 5.3 - 2.8

∴ The difference = 2.5 miles

Marsh Trail is longer than Woodland trail by 2.5 miles

You can split the figure into a top and bottom box.
Top box has the measurements of 3 by 18 by 20. When you multiply those together you get the volume of that box- 1080.
Bottom box has the measurements of 15 by 8 by 8. Multiplied together for the volume is 960.
Adding the top and bottom box together (1080+960) you get a total of 2040 yards cubed.

Answer:

$\frac{6}{25}$

Step-by-step explanation:

$P(A) = \frac{number \: of \: times \: A \: occurs}{total \: number \: of \: spins}$

$P(A) = \frac{12}{12 + 16 + 13 + 9} = \frac{12}{50} = \frac{6}{25}$
