divide total miles by time
725/8 = 90.625 miles per hour
Given:
The pairs of angles are:
36°,24°
18°,72°
96°,84°
To find:
Whether each pair of angle measurements are complementary, supplementary or neither.
Solution:
Two angles are complementary if there sum is 90 degrees.
Two angles are supplementary if there sum is 180 degrees.
For 36° and 24°,
So, this pair is neither complementary not supplementary.
For 18° and 72°,
So, this pair is complementary.
For 96° and 84°,
So, this pair is supplementary.
4. 64/16 = 4. It drops 16 feet per second and 64 feet in total. It takes 4 seconds for a dropped object to fall 64 feet.
5. This one is a bit tricky, but the height would be 3. The formula would be 3 * 9 * 9. The width and length would both be 9. The height would be 3. 9 * 9 * 3 = 243. The volume of the rectangular prism would be 243 cubic centimeters.
6. Okay. Let’s see. 233 - 64 = 169. 169 squares is 13. The longest edge of the deck is 21 feet, because 13 + 8 = 21. Taylor will need 21 feet of railing for the longest edge of her deck.
Answer:
Width = 25
Length = 25
Area = 625
Step-by-step explanation:
The perimeter of a rectangle is given by the sum of its four sides (2L+2W) while the area is given by the product of the its length by its width (LW). It is possible to write the area as a function of width as follows:
The value of W for which the derivate of the area function is zero is the width that yields the maximum area:
With the value of the width, the length (L) and the area (A) can be also be found:
Since the values satisfy the condition W≤L, the answer is:
Width = 25
Length = 25
Area = 625
