Answer:
n = 40
Step-by-step explanation:
A fraction can be equivlent to another fraction, right? so 1/3 = ?/600 - 3*200 = 600 and 1*200 = 200 so 5n/600 should be equal to 200/600 and since 5n = 200 we divide by 5 on both sides and get n = 40
<h3><u>Radius as function of volume is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The volume of cone is given as</u></em>:
Where,
r is the radius
h is the height
From given,
height = 20 inches
From formula,
Rearrange , so that r is alone in left side of equation
Substitute h = 20
Thus, radius as function of volume is:
Answer:
Step-by-step explanation:
We can use the relationship between a radius and a diameter to find which circle has a greater area without calculating it.
We know that the diameter is twice the size of the radius.
- The diameter is the distance across the circle at the center
- The radius is the distance from the center of a circle to the edge
Using this, we can find the radius of a circle that has a diameter of 6.
Since the diameter is twice the radius, the radius will be half the diameter.
Since the diameter is 6, the radius is 3.
Circle areas can be calculated with the following formula, where r is the radius:
Using this, we know that a higher value of r will get us a greater area. Therefore, we know that the greater value (3 or 4) will get us the greater area.
Since 4 is greater than 3, we know that the circle with the radius of 4 (Ava’s) will have a greater area.
Hope this helped!
Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
