Step-by-step explanation:
5,500 divided by 785 = 7.006, which can be rounded to 7.
Answer:
4 units
Step-by-step explanation:
Create an equation where w is the width of the rectangle
Use the area formula, A = lw.
Since the length is the sum of the width and 1, it can be represented by w + 1
Plug in this and the area into the formula, and solve for w
A = lw
20 = (w + 1)(w)
20 = w² + w
w² + w - 20
(w + 5)(w - 4)
Solve for w:
w + 5 = 0
w = -5
w - 4 = 0
w = 4
Since the width cannot be negative, the answer must be 4.
So, the width of the rectangle is 4 units.
Answer:
The tower is approximately 381 feet high.
Step-by-step explanation:
Refer to the sketch attached. The height of the tower can be found in two parts:
- The part above the window, and
- The part under the window.
Each part can be seen as a leg of a right triangle. The other leg is the distance between the building and the tower and is 300-feet long. The angle opposite to the leg is given.
- The length of the upper part is
feet. - The length of the lower part is
.
The height of the tower is the sum of the two parts:
feet.
Answer:Both of them are not simplified
