A triangle has an area of 360 square feet. The height is 36 feet. What is the length of the base (in feet)?

garik1379 [7]

Step-by-step explanation:

Length of base = 20cm

We will take the base as "b"

Area of a triangle = 1/2 x base x height

So the total area = 360 square feet

360 square feet = 1/2 x b x 36

360 = 36b /2

360 = 18b

b = 360/18

b = 20

So, Length of base = 20 cm

Let's check:

1/2 x 20 x 36 = 360

Which is the correct area!

Hope this helps!

How would I do the steps to solve this?

Answer:

The maximum revenue is 16000 dollars (at p = 40)

Step-by-step explanation:

One way to find the maximum value is derivatives. The first derivative is used to find where the slope of function will be zero.

Given function is:

$R(p) = -10p^2+800p$

Taking derivative wrt p

$\frac{d}{dp} (R(p) = \frac{d}{dp} (-10p^2+800p)\\R'(p) = -10 \frac{d}{dp} (p^2) +800 \ frac{d}{dp}(p)\\R'(p) = -10 (2p) +800(1)\\R'(p) = -20p+800\\$

Now putting R'(p) = 0

$-20p+800 = 0\\-20p = -800\\\frac{-20p}{-20} = \frac{-800}{-20}\\p = 40$

As p is is positive and the second derivative is -20, the function will have maximum value at p = 40

Putting p=40 in function

$R(40) = -10(40)^2 +800(40)\\= -10(1600) + 32000\\=-16000+32000\\=16000$

The maximum revenue is 16000 dollars (at p = 40)

At a certain time in the afternoon a light pole casts a shadow that us 11 ft 9 in long. At the same time, a woman of height 4 ft

il63 [147K]

We have similar triangles so

$\dfrac{4'6"}{18"} = \dfrac{x}{11'9"}$

$x= \dfrac{ (12(11)+9 )(12(4)+6) }{18 } = 423 \textrm{ inches}$

Answer: 35' 3"
