Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
<em>(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5</em>
<em>This would get of / 5 so you don't need to divide by 5</em>
362 + x = 460
Subtract 362 from each side
x = 98
The grapefruit should be <u>sliced</u> 1 inch from its center in order that both circular sections have the same radius as the two halves of a perfectly sliced orange with a 4-inch diameter
Since the grapefruit has a diameter of 6 inches and we require its cut cross-section to have a diameter of 4 inches as that of a perfectly sliced orange with a 4-inch diameter.
For the circular section to have a diameter of 4 inches, we cut it with a radius of 4/2 = 2 inches from the top.
<h3>Distance from center at which grapefruit is sliced</h3>
Now, since the radius of the grapefruit is 6/2 = 3 inches, and radius of the circular cross-section is 2 inches, the distance from the center of the grapefruit the circular section should be sliced, d = radius of grapefruit - radius of section = 3 inches - 2 inches = 1 inch.
So, the grapefruit should be <u>sliced</u> 1 inch from its center in order that both circular sections have the same radius as the two halves of a perfectly sliced orange with a 4-inch diameter
