Answer: 90%

Step-by-step explanation:

Step 1: You would get the greater value (50) and the lower value (26). You would subtract those numbers.

Step 2: You would get 24 when you subtract those numbers. Divide that number by 26.

Step 3: This is optional. You can simply those numbers to make it easier to divide.

Step 4: Divide

Step 5: You would get 0.9230769

Step 6: Move the decimal point 2 times to the right. So you would get 92%

The volume of a cone is 36 min 3. What is the volume of a cylinder with the same base and height as the cone?

Rina8888 [55]

Answer: LAST OPTION

Step-by-step explanation:

The formula for calculate the volume of a cone is:

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

Where r is the radius and h is the height.

The formula for calculate the volume of a cylinder is:

$V_{cy}=r^2h\pi$

Where r is the radius and h is the height.

As you can see, the difference between the the formulas is that <em>r²hπ</em> of the cone is divided by 3. Therefore, if you know the volume of the cone and you know that cylinder has the same base and height as the cone, you have to multiply the volume of the cone by 3.

Therefore, the result is:

$_{cy}=36in^3*3=108in^3$

Deon plots points to show the time it takes him to swim laps on two days. Is there a proportional relationship between the numbe

Sever21 [200]

Answer:

There's no proportional relationship between number of laps and minutes.

Step-by-step explanation:

The graph given above is a straight line graph, however, it does not cut across the point of origin (0, 0). As a result of this, it would be difficult to get a constant of proportionality, as you'd likely get different constant of proportionality between different points on the line. Thus, the ratio of y and x for each set of points may vary.

So therefore, the relationship between the x and y cannot be proportional.

We can conclude that the graph does not represent a proportional relationship between number of laps and minutes.
