The formula for area of a triangle is: 1/2 x base x height.

You are given the height of 4 and the area of 4.

Replace those in the formula and solve for x ( base)

4 = 1/2 x base x 4

Divide both sides by 4:

1 = 1/2 x base

Multiply both sides by 2:

2 = base

x = 2

Answer:

2=X

Step-by-step explanation:

The area of a triangle is ..

A=1/2 (b×h)

b=base

h=height

Therefore you must plug in what you know and work backwards

4=1/2 (x×4)

×2=×2

___ _________

8=(x×4)

÷4= ÷4

____ _____

2=x

Solve formula for B v= 1/3Bh
MaRussiya [10]

v = 1/3Bh

Divide both sides by h.

v/h = 1/3B

Multiply both sides by 3.

3v/h = B

\boxed {B = \frac{3v}{h} }

A cylindrical tank has a radius of 15 ft. and a height of 45 ft. How many cubic feet of water can the tank hold?
vladimir1956 [14]
The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:

1) plug in the values
- pi(15^2) x 45

2) solve for the base area of one of the circles
- pi(15^2)=225pi

3) multiply the base area by the height
- 225pi x 45 = 10,125pi

4) final answer: the tank can hold 10,125pi cubic feet of water

NEED HELP RIGHT AWAY!!!! identify some of the key features of the graph. That is, determine if the function is monotonically inc
Anna11 [10]

Answer: the function is monotonically increasing since the output values are continually getting larger. This also tells us that the end behavior of the function is infinity.

The x-intercept is (0,0), the y-intercept is (0,0), and the endpoint too is (0,0).

The domain of the graph is all values greater than or equal to 0, and the range is all positive output values.
