Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 24
and AD = 12, what is the length of AC?
A
12
D
24
Answer: x=48
Step-by-step explanation:
The length AC of the right-angle triangle will be 48 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.
AC / AB = AB / AD
AC / 24 = 24 / 12
AC = 48 units
The length AC of the right-angle triangle will be 48 units.

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?
Use 3.14 for π, and do not round your answer.
Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a typical ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm

Solve for x. 20x + 5 =5x+65
Answer:
x = 4
Step-by-step explanation:
subtract 5 from all sides
20x+5-5=5x+65-5
simplify
20x=5x+60
subtract 5x from both sides
20x-5x=5x+60-5x
simplify again
15x=60
Divide both sides by 15
15x/5 = 60/15
lastly simplify to get your answer of
x = 4

What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?
Answer:
y = -2x - 5
Step-by-step explanation:
x1 = -3 , y1 = 1 ; m = -2
point slope form : y - y1 = m(x -x1)
y - 1 = -2(x - [-3])
y - 1 = -2(x + 3)
y - 1 = -2x + 3*(-2)
y - 1 = -2x - 6
y = -2x - 6 + 1
y = -2x - 5
