The formula for area of a triangle is A = bh/2, where b is the base length and h is the height of the triangle. For this triangle, the base is twice as big as the height; the base and height are represented as follows.
Height: h
Base: 2h
The area of the triangle is 64. Plug all values and expressions accordingly into the formula for area and solve algebraically for h.
A = bh/2
64 = 2h(h)/2
64 = 2h²/2
64 = h²
8 = h
b = 2h
b = 2(8)
b = 16
Answer:
The height of the triangle is 8 units and the base is 16 units.
Answer:
$18,112.45 (nearest cent)
Step-by-step explanation:
Let y = value of the boat
Let x = the number of years
If the boat depreciates in value by 15% each year, then each year that goes by, it is worth 85% of the previous year's value (since 100 - 15 = 85)
85% = 85/100 = 0.85
Therefore, the equation is: 
So, when x = 10:
Answer:
$647.50
Step-by-step explanation:
111 x 2/3 = 74
111 x 1/3 = 37
$4.50 x 37 = $166.50
$6.50 x 74 = $481
$481 + $166.50 =
$647.50

Answer:
Step-by-step explanation:
The easiest way to do this is to assume you don't get a 1 or 2. You make your first draw from 8.
8 * 7 * 6 * 5 = 1680
The total number of ways of drawing 4 marbles is
10*9 * 8 * 7 = 5040
P(`(1 or 2) ) = 1680 / 5040 = 0.33333
The probability of getting a 1 or 2 in 4 throws = 1 - 0.3333 = 0.66667
Answer:
0
Step-by-step explanation:
the probability that this person doesn't use any facility = 0/130
= 0
