Answer:
x = 8/√3
Step-by-step explanation:
We solve that above question using the trigonometric function of sin
Sin theta = Opposite/Hypotenuse
Theta = 60°
Opposite = 4
Hypotenuse = x
Hence,
Sin 60 = 4/x
Cross Multiply
sin 60 × x = 4
x= 4/sin 60
in rational form
sin 60 = √3/2
Hence, x = 4/ √3/2
= 4 ÷ √3/2
= 4 × 2/√3
= 8/√3
Yes she got her money back. To be exact she made a profit of $6.84!
2.58+2.58=5.16 This is how much she has to make to make a profit.
0.75*16=12
She made $12 in total :]
Answer:
34.0 degrees, 29.6 feet in Diameter.
This is a right triangle trigonometry question.
Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.
Use Inverse Tangent function to find the angle of repose
round to 34.0
then use the angle of repose to solve trigonometric function of the tangent for the radius of the other cone.
switch denominator and tangent
multiply by 2 to get diameter of second cone
14.82*2≈29.6
hopefully this helps!
divide gallons used by time
4 3/8 = 35/8
2 1/2 = 5/2
35/8 / 5/2 = 35/8 * 2/5 = 70/40 = 7/4 (simplest form) = 1 3/4 gallons per hour
This point is not a solution to those lines.
