Step-by-step explanation:
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.
Answer: 137
Step-by-step explanation: 11^2−5+(4)(7)/4(3)
121−5+(4)(7)/4(3)
116+(4)(7)/4(3)
116+(28/4)(3)
116+(7)(3)
116+21
137
Answer:
-2
Step-by-step explanation:
Let x be the unknown value
Log₆ ( 1/36) = x
( 1/36) = 36⁻¹ = (6²)⁻¹ = 6⁻²
Log₆ ( 1/36) = Log₆
6⁻² = -2 Log₆
6
Log₆
6 = 1
-2 Log₆
6 = -2(1) = -2
Answer:
Step-by-step explanation:
We have two congruent right triangles and three rectangles.
First, calculate the length of the hypotenuse using the Pythagorean theorem:
We have
Substitute:
The formula of an area of a right triangle:
Substitute:
The formula of an area of a rectangle:
w - width
l - length
Rectangle 1:
w = 15, l = 22
Rectangle 2:
w = 17, l = 22
Rectangle 3:
w = 8, l = 22
The Surface Area of the triangular prism:
Substitute:
