I found a similar problem. This is its table:
Volunteering
Student Time(hours)
Amy 4 5/6
Beth 6 1/2
Victor 5 3/4
Cal 5 2/3

Match each pair of students with the difference between how much time they spent volunteering.

Amy and Victor : 11/12 HOURS
Amy: 4 5/6 → 29/6 ; Victor: 5 3/4 → 23/4
29/6 - 23/4 = 29/6(2/2) - 23/4(3/3) = 58/12 - 69/12 = -11/12

Cal and Beth : 5/6 HOURS
Cal : 5 2/3 → 17/3 ; Beth: 6 1/2 → 13/2
17/3 - 13/2 = 17/3(2/2) - 13/2(3/3) = 34/6 - 39/6 = -5/6

Beth and Victor : 3/4 HOURS
Beth: 6 1/2 → 13/2 ; Victor: 5 3/4 → 23/4
13/2 - 23/4 = 13/2(2/2) - 23/4(1/1) = 26/4 - 23/4 = 3/4

28/80 and then you simplify it by dividing the numerator and denominator by 4 and you get 7/20.

B. 7/20 is the correct answer

Mike is pouring a two foot cement sidewalk around the perimeter of his swimming pool. His swimming pool measures 6 feet by 14 fe

frosja888 [35]

9 inches * 1 foot / 12 inches
= 3/4 feet deep

Area of the sidewalk:
= the sides of the pool * the width of the sidewalk + the corners of the sidewalk (width * width)
= 2 sides * 6 (feet / side) * 2 feet + 2 sides * 14 (feet / side) * 2 feet + 4 corners * (2 feet * 2 feet / corner)
= 12 feet * 2 feet + 28 feet * 2 feet + 4 * 2 feet * 2 feet
= 24 feet^2 + 56 feet^2 + 16 feet^2
= 96 feet^2

Volume:
= 96 feet^2 * 3/4 feet
= (96 * 3 / 4) feet^3
= (19 * 3) feet^3
= 57 feet^3

Answer:

3.58

Step-by-step explanation:

Given :

y = 2x + 4 -------- eq1

y = 2x - 4 -------- eq2

sanity check : both equations have same slope, so we can conclude that they are both parallel to one another.

Step 1: consider equation 1, pick any random x-value and find they corresponding y-value. we pick x = -2

This gives us y = 2(-2) + 4 = 0

Hence we get a point (x,y) = (-2,0)

Step 2: express equation 2 in general form (i.e Ax + By + C = 0)

y = 2x-4 -------rearrange---> 2x - y -4 = 0

Comparing with the general form, we get A = 2, B = -1, C = -4

Recall that the distance between 2 parallel lines is given by the attached formula (see attached picture).

substituting the values for A, B, C and (x, y) from the previous step:

d = | (2)(-2) + (-1)(0) + (-4) | / √(2² + (-1)²)

d = | -4 + 0 - 4 | / √(4 + 1)

d = | -8 | / √5

d = 8 / √5

d = 3.5777

d = 3.58 (rounded 2 dec. pl)
