Answer:

100

Step-by-step explanation:

In a 45-45-90 triangle, the hypotenuse is always larger than either of the legs by a factor of $\sqrt{2}$ . x is therefore:

$100\sqrt{2}\div \sqrt{2}=100$

Answer:

Step-by-step explanation:

h(t) = 841 - 16t

[Is this written correctly? The time is usually t^2, not t. I'll solve with the written equation, but check the equation]

The height at ground level is 0, so we want the value of t when h(t) = 0:

0 = 841 - 16t

-16t = -841

t = 53 seconds

One can also graph this formula and find the time to hit the ground at the point the line intersects the x axis (x = 0).

====

If the equation should have read h(t) = 841 - 16t^2, solve it as above, setting h(t) = 0.

t = (29/4) seconds

This can also be graphed.

a silo is shaped like a cylinderwith a cone on top. the radii of the bases of the cylinder and cone are both equal to 8 feet. th

Ymorist [56]

Answer:

5430.85 square feet

Step-by-step explanation:

Height of the cylindrical part of the cilo = 25 feet

radius of the base cylindrical part of cilo = 8 feet

Now volume of cylindrical part of cilo = $\pi r^{2} h$

Volume of cylindrical part of cilo = $\pi(8^{2})25$ = $1600\pi square feet$

Now,

Height of the conical part of cilo = 6 feet

Radius of the conical part of cilo = 8 feet

Volume of the conical part of cilo = $\frac{1}{3}\pi (8^{2})6$ = $128\pi square feet$

Volume of the entire cilo = $1600\pi + 128\pi = 1728\pi$

since $\pi =\frac{22}{7} therefore,$

volume of entire cilo = $\frac{22}{7} (1728)$ = 5430.85
