Answer:
13.04 cm^2
Step-by-step explanation:
Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm
The Area of a circle is A = πr^2 = πd^2/4
Larger Circle divide the diameter by 2 = 6.25 cm
Smaller Circle dive the diameter by 2 = 1.75 cm
Using above formula A = 122.71846303085 cm^2 &
Finally we deduct the smaller Area from the larger Area
A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2
122.71846303085 cm^2 - 9.6211275016187 cm^2 =
113.0973355292 cm^2 thus 13.04 is your answer since I used the
π = 3.1415926535898
A = area
π = pi = 3.1415926535898
Answer:
x-0.33x = 0.67x
Step-by-step explanation:
Given : A new soup recipe contains 33% less sodium per serving than the old soup recipe.
The old soup recipe contained x milligrams of sodium per serving.
To Find: Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe
Solution :
Since we are given that old recipe contains x milligrams of sodium per serving
And new recipe contains 33% less sodium per serving than the old soup recipe.
So, 33%of x = 0.33x
Since new recipe contains 33% less sodium than old recipe:
⇒x-0.33x
or
⇒(1-0.33)x
⇒0.67x
Thus expressions which could represent the amount of sodium per serving, in milligrams, in the new soup recipe :
x-0.33x or 0.67x
We know that the opposite is the additive inverse.
For example, 8+(−8)=0 where 0 is the identity for addition.
Given that we have to compute the sum of 5x+20 and the opposite.
Given
5x+20
opposite of 5x+20 = -(5x+20)
so
The sum of 5x+20 and the opposite:
5x+20 + -(5x+20)
Distribute the Negative Sign
Combine Like Terms
Therefore, the sum of 5x+20 and the opposite is: 0
Thus, the equivalent expression is:
