Answer:
48
Step-by-step explanation:
Remark
Use a^2 + b^2 = c^2 to solve for the height.
Givens
c = 10
b = 6
h = ?
Solution
b^2 + h^2 = c^2
6^2 + h^2 = 10^2
36 + h^2 = 100 Subtract 36
h^2 = 100 - 36
h^2 = 64 Take the square root of both sides
sqrt(h^2) = sqrt(64)
h = 8
The height = 8
Area = 1/2 * b * h
Area = 1/2 *12 * 8
Area = 48
Comment
You might wonder where the 12 came from. It wasn't given The base is the whole line across the bottom. 1/2 of it is six. The whole base = 12
<em><u>Question:</u></em>
The length of a room is 18 1
/2 feet. If using 1
/4 inch = 1 foot scale, what would be the length of a wall on a blueprint of a floor plan?
<em><u>Answer:</u></em>
The length of a wall on a blueprint of a floor plan is 
<em><u>Solution:</u></em>
Given that,
The scale given is:
To find: Length of a wall on a blueprint of a floor plan
Let "x" be the length of a wall on a blueprint of a floor plan
Then from given,
This forms a proportion and we can solve by cross multiplying
Thus length of a wall on a blueprint of a floor plan is
Answer:
5/12 = r
Step-by-step explanation:
-1/3 = r - 3/4
+3/4 +3/4
5/12 = r
Sig Figs, as they are also known, are important only in Science. But there are three ways you can determine how many sig figs there are. Non-Zero digits are sig figs. Any zeros between two sig figs are significant. (EX: 7008) And, lastly, A final zero(s) in a decimal are significant. (EX: 0.76540800) Last two zeros are significant.
Answer:
g(3) = -5
Step-by-step explanation:
g(x) = -x - 2
g(3) = -3 - 2
g(3) = -5
