I would believe A.
4x is a multiple is 2x and you can multiply the second equation by 2, then use elimination.
The ' c ' in 'gcf' and in 'lcm' stands for 'common'. 'Common' means 'same for all of them'. There's nothing common until you have at least two things. There's no such thing as the gcf or the lcm of only one number.
Answer:
A
Step-by-step explanation:
we can find using the trigonometric formulas
we can find y by using cosine.
cos = adj / hyp
cos 60 = y / 10
y = 10 cos 60
y = 5
now we can use the Pythagorean theorem since we have the base and hyp
a² + b² = c²
5² + b² = 10²
25 + b² = 100
b² = 75
b = 5√3
Answer:
(Approximation to the nearest thousandth)
Step-by-step explanation:
The area of a cylinder can be determined by the formula:
(We know that the radius, r, is 2m, and the height, h, is 5m, so we can substitute them into the formula to calculate the volume of this cylindrical tank)
(Simplify)
