Answer:

A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number. By definition, for any number x, x% = x100.

Cos90degrees cos30 degrees + sec-squared45degrees sin30degrees - cos270degrees sin180degrees
yawa3891 [41]

Step-by-step explanation:

\cos 90 \cos 30 + \sec^2 45 \sin 30 - \cos 270 \sin 180

But we know that

\cos 90 = \cos 270 = \sin 180 = 0

and

\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}

so this leaves us with just

\sec^2 45 \sin 30 = (\sqrt{2})^2  \left(\dfrac{\sqrt{3}}{2} \right)= \sqrt{3}

Calculate the slant height for the given cone.Round to the nearest tenth. Diameter =8cm
Karo-lina-s [1.5K]

Answer:

1) The slant height = 9.8 cm ⇒ (C)

2) The slant height = 11.4 cm ⇒ (D)

Step-by-step explanation:

1) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 8 cm

∴ Radius = 4 cm

∵ Height = 9 cm

∴ Slant height = √(4² + 9²) = √97 = 9.8 cm ⇒ (C)

2) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 18 cm

∴ Radius = 9 cm

∵ Height = 7 cm

∴ Slant height = √(9² + 7²) = √130 = 11.4 cm ⇒ (D)
