Answer: the intersection of plane A and plane S will be: line CW
the intersection of lines N and K is: point V
point X is the intersection of: line M and plane A
Step-by-step explanation:
A and E both solve at point (3,6)
Answer:
A. 754 cm²
Step-by-step explanation:
Amount of cardboard needed = surface area of the cone
Curved surface area of the cone = πrl
Where,
π = 3.14
r = ½(20) = 10 cm
l = 24 cm
Plug in the values into the formula
Curved surface area = 3.14 × 10 × 24 = 753.6 ≈ 754 cm²
Calculate the zero function using the location of the x-intercept.
Plot the point of the linear functions.
The new crew works at the rate 1/12 apt/hr.
The old crew works at the rate 1/6 apt/hr.
Let x = hours required to paint the apartment when the two crews work together.
That is,
(1/12 + 1/6 apt/hr)*(x hr) = (1 apt)
(3/12)x = 1
(1/4)x = 1
x = 4 hours
Answer: 4 hours
