Three friends recorded, in different units, the lengths of the hopscotch paths they made.
ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>
  • Make sure all distances use the same units.
  • If necessary convert the distances.
  • Compare the distances.

Based on this, let's make sure all distances are in feet.

  • Cassey: 94 feet

  • Jasmin: 1100 in or 91.66 feet
  • Each inch is equivalent to 0.0833
  • 1100 x 0.0833 = 91.66

  • Dustin: 32 yards or 96 feet
  • 1 yard = 3 feet
  • 32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.

Find the length of the missing side. triangle with an 8 inch side and 12 inch side with a right angle 8.9 in. 104 in. 4 in 14.4
Mamont248 [21]

Given:

In a triangle, length of one side is 8 inches and length of another side is 12 inches, and an angle is a right angle.

To find:

The length of the missing side.

Solution:

In a right angle triangle,

Hypotenuse^2=Perpendicular^2+Base^2

Suppose the measures of sides adjacent to the right angle are 8 inches and 12 inches.  

Substituting Perpendicular = 8 inches and Base = 12 inches, we get

Hypotenuse^2=8^2+12^2

Hypotenuse^2=64+144

Hypotenuse^2=208

Taking square root on both sides, we get

Hypotenuse=\sqrt{208}

Hypotenuse=14.422205

Hypotenuse\approx 14.4

The length of the missing side is 14.4 inches. Therefore, the correct option is D.

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need
PSYCHO15rus [73]

Answer: 14gallons

Step-by-step explanation:

12gallons/144miles = 1gallon/12miles

Therefore 6gallons = 12*6 = 72miles.

In order to cover 240miles, she will need 240/12 = 20gallons.

20-6 = 14gallons

She will need 14gallons of gas more.
