Answer:

to find the volume of a cylinder

V=π x r^2 x h

now since we want the whole figure were going to add up the two heights to get one height number 4ft + 5ft = 9ft

V= 3.14 x 3^2ft x 9ft

V= 3.14 x 9ft^2 x 9ft

V= 254.34

Answer:

9.2

Step-by-step explanation:

So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.

Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.

this leads to 9.2 as our answer

For your rock collection display, you want to have at most 25 samples.

mezya [45]

Answer:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The graph is attached.

Step-by-step explanation:

Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.

You know that you want to to have at most 25 samples, then:

$y\leq 25-x$

And you want to have at least 3 times as many sedimentary samples as

metamorphic samples, then:

$y\geq 3x$

Therefore, the system of inequalities that model the situation is:

$\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.$

The y-intercept of the line $y=25-x$ is:

$y=25-(0)\\\\y=25$

And the x-intercept is:

$0= 25-x\\\\x=25$

Knowing this, you can graph the line

The y-intercept of the line $y= 3x$ is:

$y=3(0)\\\\y=0$

And the x-intercept is:

$0= 3x\\\\x=0$

Knowing this, you can graph the line.

Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.

Suppose there is a 1.1 degrees Fahrenheit drop in temperature for every thousand feet that an airplane climbs into the sky. If t

sp2606 [1]

Answer:

47.6 Degree Fahrenheit

Step-by-step explanation:

Given:

The Airplane is on the ground level at a temperature 59.7 Fahrenheit. Every 1,000 feet there will be drop in temperature which is 1.1 degrees Fahrenheit.

Initial Temp = 59.7 Fahrenheit

Distance Covered = 11,000 Ft

Explanation:

This means the Ground level is zero feet as the Airplane stands there.

Later, it climbs into the sky with 11,000 altitude.

That is $11 * 1000$

For every 1,000 there is decrease in temperature of 1.1 degree Fahrenheit

Therefore, 11 times the temperature will decrease

That is $11 * 1.1$

12.1 Degree temperature will drop at 11,000 feet

Therefore

Temperature at 11,000 feet will be $59.7 - 12.1$

47.6 Degree Fahrenheit
