Answer:

ST = 20

Step-by-step explanation:

RT is the sum of RS and ST

Replacing with length you get:

17 + x + 6 = 3x - 56

17 + 6 + 5 = 3x - x

28 = 2x

14 = x

ST = x + 6 = 14 + 6 = 20

Answer:

greater than or equal $46$ to and less than $96$

Step-by-step explanation:

GIVEN: On the first four exam your grades are $76,78,73$ and $77$ . You are hoping to earn a C in the course. This will occur if the average of your fifth exam grades is greater than or equal to $70$ and less than $80$ .

TO FIND: range of grades on the fifth exam will result in earning a C.

SOLUTION:

Total number of marks scored till first four exams $=76+78+73+77$

$=304$

let average marks scored after fifth exam be $S$ .

let marks scored in fifth exam be $x$

$S=\frac{76+78+73+77+x}{5}$

$S=\frac{304+x}{5}$

Now, to earn a C the average must be greater than or equal to $70$ and less than $80$

$70\leq S< 80$

$70\leq \frac{304+x}{5}$

when

$\frac{304+x}{5}\geq 70$

$304+x\geq 350$

$x\geq 46$

when

$\frac{304+x}{5}$

$304+x$

$x$

Hence grades in fifth exam must be greater than or equal $46$ to and less than $96$

Answer:

Third answer choice, $312\pi$ cubic millimeters

Step-by-step explanation:

The composite figure is attached.

The volume of the figure is the volume of the oblique cone PLUS the volume of half the sphere.

The formula for volume of oblique cone is:

$V=\frac{1}{3}\pi r^2 h$

The formula for volume of half sphere is:

$V=\frac{2\pi r^3}{3}$

First, volume of oblique cone:

$V=\frac{1}{3}\pi r^2 h\\V=\frac{1}{3}\pi (6)^2 (14)\\V=168\pi$

Second, volume of half sphere:

$V=\frac{2\pi r^3}{3}\\V=\frac{2\pi(6)^3}{3}\\V=144\pi$

Total Volume of this composite figure is:

$168\pi + 144\pi = 312\pi$
