Answer:
Height of the cliff = 13.66 m
Step-by-step explanation:
Let the height of the cliff is 'x' m and distance between the base of the cliff and the boat is 'y' m.
From right triangle AOC,
tan 30° = 
y = 
------(1)
From right angle triangle BOC,
tan 45° = 
x = y - 10
y = x + 10 -------(2)
From equations (1) and (2),
x = 13.66 m
Therefore, height of the cliff is 13.66 m.
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
Answer: Mrs. Alberts spent $1,050 on the floor.
Step-by-step explanation: First lets find the area to get the total amount of square feet by multiply length by width.
12.5 x 7 = 87.5 square ft.
We know that it costs $12 per square foot, and we have 87.5 square feet.
So, multiply 12 by 87.5 to find the cost that Mrs, Alberts will spend on the floor.
12 x 87.5 = 1050, or $1,050 for the total area of the floor.
Answer:
Step-by-step explanation:
Volume of 100 pages of the book =20 inches cube.
Step-by-step explanation:
Given : A 300-page book is 10 inches long, 8 inches wide, and 3/4 inches tall.
To find : The volume of 100 pages of the book.
Solution :
Formula to find the volume of book is
Where Length L=10 inches
Breadth B= 8 inches
Height H= inches.
Volume of the book with 300 pages is
Volume of 300 pages of the book = 60 inches cube.
Volume of 1 page of the book = inches cube
Volume of 100 page of the book = inches cube
Volume of 100 pages of the book =20 inches cube.
