Mathematics
2 answers:
marishachu [46]3 years ago
5 0

Answer:

d 150.7 ft³

Step-by-step explanation:

volume of a cone = πr²h/3

π = 3.14

r = diameter/2 = 8/2 = 4ft

h = 9ft

therefore volume of the cone = (3.14 × 4² × 9)/3 = 150.7 ft³

Whats the percent difference of 154 and 440
Semmy [17]
This would be a percent increase, so the formula would be:

New amount - Original amount / Original amount

Replace the numbers:

440 - 154 / 440

Simplify.

286 / 440

The chance would be 0.65, or 65%.

From a window 20 feet above the ground, the angle of elevation to the top of a building across
Nikitich [7]

Answer: The answer is 381.85 feet.

Step-by-step explanation:  Given that a window is 20 feet above the ground. From there, the angle of elevation to the top of a building across  the street is 78°, and the angle of depression to the base of the same building is 15°. We are to calculate the height of the building across the street.

This situation is framed very nicely in the attached figure, where

BG = 20 feet, ∠AWB = 78°, ∠WAB = WBG = 15° and AH = height of the bulding across the street = ?

From the right-angled triangle WGB, we have

\dfrac{WG}{WB}=\tan 15^\circ\\\\\\\Rightarrow \dfrac{20}{b}=\tan 15^\circ\\\\\\\Rightarrow b=\dfrac{20}{\tan 15^\circ},

and from the right-angled triangle WAB, we have'

\dfrac{AB}{WB}=\tan 78^\circ\\\\\\\Rightarrow \dfrac{h}{b}=\tan 15^\circ\\\\\\\Rightarrow h=\tan 78^\circ\times\dfrac{20}{\tan 15^\circ}\\\\\\\Rightarrow h=361.85.

Therefore, AH = AB + BH = h + GB = 361.85+20 = 381.85 feet.

Thus, the height of the building across the street is 381.85 feet.

What is th result of converting 20 ounces into pounds?
Harrizon [31]
Hello!

The Correct Answer would be:

"1.25 Pounds"

Why? Well:

1 ounce (oz) is equal to 0.0625 pounds (lb).

1 oz = (1/16) lb = 0.0625 lb

The mass m in pounds (lb) is equal to the mass m in ounces (oz) divided by 16:

m(lb) = m(oz) / 16


So as Result, The Answer is 1.25 Pounds.


Hope this Helps! Have A Wonderful Day! :)
