Consider the two similar cones. What is the height of the smaller cone?

USPshnik [31]

Answer:

Step-by-step explanation:

Since the cones are similar then the ratio of corresponding sides are equal, that is

$\frac{12}{18}$ = $\frac{h}{45}$ ( h is the height of the smaller cone )

Cross- multiply

18h = 540 ( divide both sides by 18 )

h = 30 cm → B

The chosen topic is not meant for use with this type of problem. Try the examples below.

$cot (3x),x=\frac{2\pi }{3}$

$cot ( \frac{x}{2}, x=\frac{\pi }{2}$

$cos (x), x = \frac{x}{2}$

What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals nega

RUDIKE [14]

we have

the equation of the line is $y=-2x$

the points are

$A(3,-6)\\B(0,0) \\C(-3,6)$

Method 1

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem we have a direct variation

The constant of proportionality k is equal to the slope of the line

$k=-2$

$m=-2$

therefore

the answer is

the slope of the line is equal to

$m=-2$

Method 2

we know that

the formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(3,-6)\\B(0,0)$

substitute in the formula

$m=\frac{0+6}{0-3}$

$m=\frac{6}{-3}$

$m=-2$

therefore

the answer is

the slope of the line is equal to

$m=-2$

cupoosta [38]

Answer:

If you were to make a 360 degree circle and minus the 50 thats already there you get 310 the right angle on angle 5 is 90 degrees because its a right angle so then the 310-90=220 the obtuse angle on angle 2 is 180 so 220-180=40 lastly you share those forty between angles 3 and 4 and the solution is your answer.

Hi. 45 minutes out of 60 min is 3/4 of an hour. multiply 3/4 by 14 and you have 10 1/2 hours. 28 hrs - 10 1/2 is 17 1/2 hours. multiply by 60 and you have:

1050 min.
