Step-by-step explanation:

h=v/(π*r square)

divide the volume of a cylinder by the amount of the radius squared multiplied by π(pi)

340÷(π×3square)

giving you 12.025

(original in calculator=12.02504014)

The students in Roberto's school are painting a mural that will be 15 feet by 8 feet. First they make a scale drawing of the mur

bixtya [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point A:

The two-point C and y is given, where C is the scale drawing lengths and y is the actual mural lengths so, the formed equation is:

$\to \frac{c}{y}=\frac{2}{5}$

In point C :

Using the value of the scale:

let 1 feet: 20 feet

therefore the equation is:

$\to \frac{c}{y}=\frac{1}{20}$

The size of c will be the length of:

$\to c= \frac{y}{20}\\\\\to c= \frac{8}{20}\\\\\to c= 0.4\\$

The diagram c scale width will be:

$\to c= \frac{y}{20}\\\\\to c= \frac{15}{20}\\\\\to c= 0.75\\$

Solve 2x2 − 8x = −7.

leva [86]

$\sf 2x^2 - 8x = - 7 \\ \\ Subtract \ -7 \ from \ both \ sides \ of \ the \ equation. \\ \\ 2x^2 - 8x - (-7 ) = - 7 - (-7) \\ \\ 2x^2 - 8x + 7 = 0 \\ \\ Use \ quadratic \ formula \ a = 2, b = -8, c = 7 \\ \\ x = \dfrac{- b \pm \sqrt{b^2- 4ac} }{2a} \\ \\ \\ x = \dfrac{-(-8) \pm \sqrt{(-8)^2 - 4 (2) (7) } }{2(2)} \\ \\ x = \dfrac{8 \pm \sqrt{8} }{4} \\ \\ x = 2 + \frac{1}{2}\sqrt{2} \ or \ x = 2 + \frac{-1}{2} \sqrt{2}$
