17^2 - 12^2
289 - 144 = 145
Sqrt of 145 = 12.04159…
The answer rounded to two decimal places is 12.04 cm.
Answer:
a.) 61 square feet
b.) $152.50
Step-by-step explanation:
first you find the area for the rectangle
LxW=A
10x4=40
then you find the area for the triangle
(bxh)1/2=a
(6x7)1/2=21
-we get 7 from adding the height that we know (3ft) and using logic, a rectangle has equal parallel lines so the dotted line has to equal 4ft. so 3ft+4ft=7ft
then you add both areas together
40 square feet+21 square feet= 61 square feet
<em>Now</em><em> </em><em>for</em><em> </em><em>B</em><em>.</em><em>)</em>
as we know, the area of the room floor is 61sq feet. so by multiplying 2.5 and 61 you get the cost as $152.50
Answer:
-4.4 divided by 2 equals -2.2
The longer sides are slanting and the shorter sides arent
Answer:
Long = 5√3
Step-by-step explanation:
Hypotenuse = 10
Short = 5
Long = ?
Apply Pythagorean theorem to find Long:
Long² = hyp² - short²
Long² = 10² - 5²
Long² = 100 - 25
Long² = 75
Long = √75
Long = √(25*3)
Long = 5√3
