The area of any triangle is A = (1/2) (base) (height).
If the right triangle is not sitting
on its hypotenuse, then one leg
is the base, and the other leg is
the height: A = (1/2) (base leg) (height leg) .
If the triangle is isosceles, then
the legs are equal: A = (1/2) (either leg)²
You said the area is 18 in²: 18 in² = (1/2) (leg²)
Multiply each side by 2 : 36 in² = leg²
Square root each side: 6 in = leg
The answer is 640.
32 goes into 5, 6 times.
6x5=30
32-30=2. Then you bring everything down.
And have 200, 200 goes into 5, 40times.
So, you have 640
Answer:
$2.77 per quart.
Step-by-step explanation:
There are four quarts in a gallon.
4 * 3 = 12
There are 12 quarts in 3 gallons.
The price per quart should be $2.77.
Hope this helps.
Answer:
Step-by-step explanation:
a = 6
c = 6
b = 13
ac = 6 * 6 = 36
4 and 9 multiply to 36 and 4 and 9 add to 13
Let h represent the height of the triangle.
... b = 10 + 3h . . . . . . the base is 10 inches more than 3 times the height
... A = (1/2)bh . . . . . . formula for the area of a triangle in terms of base and height
... 16 = (1/2)(10 +3h)h . . . . substitute the known values
... 3h² + 10h - 32 = 0 . . . . rearrange to standard form
... (h -2)(3h +16) = 0
... h = 2 or -16/3 . . . . . . . . the negative solution is extraneous
... b = 10 + 3·2 = 16 . . . . . use the relation between b and h
The base and height of the triangle are 2 inches and 16 inches, respectively.
