Answer:
n = 6.5
Step-by-step explanation:
0.7n - 1.5 + 7.3n = 14.5
0.7n+7.3n=8n
8n-1.5=14.5
+1.5 = +1.5
---------------------
8n/8(divide) = 16/8
n=8
Attached is the solution.
The following log properties are used:
I believe 4^2/4^-2 would be equivalent to that expression
Answer:
- 63 ft²
- h = 2A/b; h = 7 ft
Step-by-step explanation:
1. Put the values where the variables are in the formula, then do the arithmetic.
... A = (1/2)bh = (1/2)(18 ft)(7 ft) = 63 ft²
2. Divide by the coefficient of h. Substitute the given values and do the arithmetic.
... A = (1/2)bh
The coefficient of h is b/2, so we divide by that—or multiply by its inverse, 2/b.
... 2A/b = h
Substituting the given numbers, you have ...
... 2(28 ft²)/(8 ft) = h = 7 ft
The height of the triangle is 7 ft.
