Answer:

The remaining number of miles to trail will be 3\frac{3}{4} miles.

Step-by-step explanation:

A group of scouts cleared tree branches from 2\frac{5}{6} i.e. \frac{17}{6} miles of trail the first day. On the second day, they cleared 3\frac{1}{4} i.e. \frac{13}{4} miles of trail.

Therefore, in two days they have cleared (\frac{17}{6} + \frac{13}{4}) = \frac{17 \times 2 + 13 \times 3}{12}  = 5 miles.

If the length of the trail is 8\frac{3}{4} i.e. \frac{35}{4} miles, then the remaining number of miles to trail will be \frac{35}{4} - 5 = \frac{15}{4} = 3\frac{3}{4} miles. (Answer)

Deon drove 16 miles which is one fourth of the way home what’s the total length of the drive
svetlana [45]
64 miles

If 16 is 1/4 of the total distance, then x (the total distance) will be 4/4. To get 1/4 to equal 4/4, you multiply it by 4. Therefore you can multiply 16 by 4 to get 64 as the answer.

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster. Which graph represents the se
Gre4nikov [31]

Given:

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.

To find:

The graph that represents the set of heights that satisfy this requirement.

Solution:

Let x be the height required for the ride.

Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.

x\geq 54

So, 54 and all values above 54 are in the solution set.

Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.

Therefore, the correct option is C.
