Answer:
where is the graph?
Step-by-step explanation:
Answer:
x = 5, y = 20
Step-by-step explanation:
Since AB and CD are parallel, then
∠ AOC and ∠ OCD are Alternate angles and congruent, thus
12x + 8 = 68 ( subtract 8 from both sides )
12x = 60 ( divide both sides by 12 )
x = 5
-------------------------------
∠ OCD and 5y + 12 are adjacent angles and supplementary, thus
5y + 12 + 68 = 180 , that is
5y + 80 = 180 ( subtract 80 from both sides )
5y = 100 ( divide both sides by 5 )
y = 20
3/4 - per skirt >> 0.75
5 5/14 - unused >> 5.36 (approximately)
5.36/0.75= 7.14666...

Answer: 720 is greater than 648
Step-by-step explanation:
The required posterboard for an art project = 4 1/2 square feet
1 square foot = 144 square inches
4 1/5 × 144 square inches
= 648 square inches.
The available posterboard is with a length of 30 inches and a width of 2 feet.
One foot = 12 inches
The area of the available posterboard 30 × 2 × 12 = 780 inches
Since the available area is greater than the required area, the posterboard will therefore be enough for the project.
Let x be the length of Daniel's wire. With the representation, Sarah's wire is 4x/5 and that of Chris is 3 time 4x/5. The equation that best represent the situation given above is,
x + 4x/5 + 3(4x/5) = 6
The value of x in ft is 1.42. Therefore, Sarah's wire which is 4x/5 is approximately 1.14 ft long.
