Answer: y = 20x+75

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The cost (y) must be equal to the product of the cost per hour of installation (20) and the number of hours that it takes (x); plus the fixed cost of parts and installation (75).

Mathematically speaking:

y = 20x+75

The length of one leg of a right triangle is 24 ft, and the length of the hypotenuse is 40 ft.

Mila [183]

H^2=x^2+y^2

y^2=h^2-x^2

y^2=40^2-24^2

y^2=1024

y=√1024

y=32 ft

.10.A cone with a height of 15 yards has a volume of 457.17 yd3 . Find the diameter of the cone

Neko [114]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ V=457.17\\ h = 15 \end{cases}\implies 457.17=\cfrac{\pi r^2(15)}{3}\implies 457.17=5\pi r^2 \\\\\\ \cfrac{457.17}{5\pi }=r^2\implies \sqrt{\cfrac{457.17}{5\pi }}=r\implies 5.39 \approx r~\hfill \boxed{\stackrel{diameter = 2r}{2(5.39) = 10.78}}$
