Find the volume and round to the nearest tenth as needed
monitta

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}

The volume of the smaller cone is V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi.

So, the volume is \frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}

A roofer props a ladder against a wall so that the top of the ladder reaches a 30-foot roof that needs repair. If the angle of e

Set this up like a right triangle with the height of the triangle as 30, the angle across from that side, the reference angle, as 55, and the base is your unknown, x.  This means that we have the angle, the side across from it, and the side adjacent to it.  That sounds like the tangent ratio to me!  Tangent of the angle is the side opposite over the side adjacent: tan(55)= \frac{30}{x}.  Solving for x: x= \frac{30}{tan(55)}.  Do that on your calculator in degree mode to get that the distance between the base of the ladder and the wall is 21 feet

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number
Radda [10]

Answer:

A. Y-68=-5(x-14)

Step-by-step explanation:

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation

We find the equation using the point slope equation of a line. This is given as:

y - y1 = m(x-x1)

The slope intercept form will be

y = -5x + b

since the amount decreases by $5 per day...

Our slope is -5 so m=-5

We have a point (x1,y1) = (14, 68)

Hence, we have:

y-68 = -5(x-14)

Option A is correct
